Electrical activity of cerebral cortex in the cat during closure of simple form of a temporary connection. The closure of a simple form of temporary connection of the summation reflex type was studied by combining light flashes with subthreshold electrical stimulation of the cortical site of representation of the right forelimb in the cat. Summation, i.e., forepaw flexion, occurred both when two subthreshold stimuli were applied simultaneously and when there was a short (tens of milliseconds) interval between the stimuli. The sequence of stimulus presentation (current + light or light + current) was immaterial. During summation there occurred changes in the configuration of the direct cortical response recorded at a distance of 2-3 mm from the stimulation site. Neurophysiological analysis of the electrical correlates of establishment of the simple form of temporary connection (study of neuronal activity, the effect of some pharmacological agents, testing by paired stimuli) suggests that the mechanism of closure under study is dependent on induction relations manifested by the enhancement of phasic changes in excitatory 2nd inhibitory processes. When the current + light combination was used, two phases of neural activity were characteristic: inhibition and a subsequent rebound. With the light + current combination, these phases were preceded by a phase of primary excitation.

Electrophoresis of isolated secretory granules from guinea-pig submaxillary gland. 1 The nature of the surface charge on secretory granules from the submaxillary gland of the guinea-pig has been studied by electrophoresis of the isolated granules. The granules suspended in buffered sucrose solutions move to the anode.2 Divalent ions reduce the anodal movements of the granules. Calcium and magnesium neutralize the net surface charge of the granules. This result supports the hypothesis that the electrostatic surface charge which can be reduced by calcium ions may be a major factor in controlling the fusion of secretory granules to the cell membrane, before release by exocytosis.3 The mechanisms which couple membrane events with enzyme or hormone release from secretory glands are considered.

Endogenous phospholipids of swine liver: effect of fat deprivation on molecular species of phosphatidylcholine and phosphatidylethanolamine. Three 1-yr-old swine and two 2.5-wk-old swine were fed a fat-free diet for 1 month and 5 months, respectively. The hepatic phosphatidylcholine and phosphatidylethanolamine were fractionated by silver ion thin-layer chromatography. A distinctive feature of the chromatographic procedure was the development of the chromatograms at low temperatures: -10 degrees C for phosphatidylcholine and 4 degrees C for phosphatidylethanolamine. The chromatographic fractions were hydrolyzed with phospholipase A(2), and the fatty acids were characterized. Significant concentrations of odd-chain saturated and unsaturated fatty acids were found in the swine deprived of fat for 5 months. The major molecular species of phosphatidylcholine in both groups contained monoenoic fatty acids: 16:0/18:1(n - 9), 18:0/18:1(n - 9), and 18:1(n - 9)/18:1(n - 9). Their concentrations changed only slightly with the diet. The molecular species of phosphatidylethanolamine were more sensitive to dietary changes. In the swine deprived of fat for 1 month, about 50% of the molecular species of phosphatidylethanolamine contained tetraenoic fatty acids: 16:0/20:4(n - 6), 18:0/20:4(n - 6), and 18:1(n - 9)/20:4(n - 6). The phosphatidylethanolamine of animals deprived of fat for 5 months contained only 3% molecular species with tetraenoic acids, 18:0/20:4(n - 6), but 36% molecular species with trienoic acids: 18:0/20:3(n - 9), 18:1(n - 9)/20:3(n - 9), 18:0/19:3(n - 8), 16:0/20:3(n - 9), and 17:0/20:3(n - 9). Doubly unsaturated species, such as 18:1(n - 9)/18:1(n - 9), 18:1(n - 9)/20:3(n - 9), and 18:1(n - 9)/20:4(n - 6), were found in both groups of swine, although their total concentrations were higher in the group deprived of fat for a longer period.

Evaluation of four blood culture systems using parallel culture methods. Commercially prepared Vacutainer thioglycolate broth with SPS (TBSPS), the B-D Vacutainer culture tube with SPS (VCT), the Pfizer E-Vac hypertonic brucella broth with SPS (BBSPS), and our own Trypticase-soy hypertonic broth with SPS (TSBH) were studied by parallel culture methods for their ability to allow the survival of a wide spectrum of organisms, their ability to allow recovery of organisms, and the time required to obtain a recovery from clinical blood cultures. Organisms considered to be clinically significant were recovered from 176 blood cultures. The TSBH system produced all 176 recoveries, the BBSPS system allowed for 170 recoveries, the TBSPS recovered 131, and the VCT accounted for 106 recoveries. The time required to recover any given organism from both the BBSPS and the TSBH systems did not exceed 48 h, whereas 86 of the 131 recoveries from the TBSPS system required more than 72 h and 74 of the 106 VCT recoveries also required more than 72 h. A wide spectrum of organisms were recovered from both the BBSPS and the TSBH systems. The TBSPS system failed to allow the recovery of many streptococci and Pseudomonas spp. and the VCT system failed to recover many organisms.


Evaluation of four slide test kits for the detection of human chorionic gonadotropin in urine. Three "indirect-type" slide tests utilizing the principle of hemagglutination inhibition and one new "direct-type" slide test employing direct agglutination were evaluated for their sensitivity in detecting human chorionic gonadotropin (HCG) in urine. The results of positive tests in a group of woman in very early pregnancy were correlated with the "days after last menses". In this series the direct slide test was the most accurate. A control must be used with each direct test to indicate interfering substances and when such are present a different test must be used. All tests were found to be of the relative sensitivity stated by the manufacturer.

Evaluation of the Gravigard intrauterine copper contraceptive device. The plastic intrauterine device is now being used as a carrier to hold the contraceptive agent (copper in this case) in the uterus.  The action of copper as a contraceptive agent is thought to be due to an alteration in intrauterine environment thus preventing implantation and causing rapid loss or destruction of the fertilized ova.  Studies show that such local use of copper appears to be safe over long-term use, and no changes in cervical cytology or endometrial histology and no evidence of tumor production due to copper have been seen.  Presented here is a study of 127 women using a Gravigard (Copper 7) IUD.  The patients ranged from 18 to 42 years old, and 33 (26%) were nulliparous.  Insertion was easy in 111 (87%), there were minor problems in 10 (8%), and difficulties in 6 (4.7%).  The majority of patients had no immediate postinsertion pain or problems, but 11 (9%) did complain of uterine cramps or symptoms of faintness or nausea.  3 patients were lost to follow-up, and the remaining 124 women were followed over a total of 1089 woman-months.  7 patients (5.5%) expelled the Gravigard, 3 (2.4%) became pregnant, and 10 (7.9%) had their IUDs removed for medical reasons.

Evidence for the presence of RNA in the purified virions of vaccinia virus. Vaccinia virus, strain WR, was propagated in HeLa cells, L mouse fibroblats, or primary chicken embryo fibroblasts in the presence of [5- (3)H]uridine. Carefully purified virions were found to contain significant amounts of labeled trichloroacetic acid-precipitable material which was rendered acid soluble when digested with pancreatic RNase or hydrolyzed in alkali. Controlled degradation of virions with Nonidet P-40 and 2-mercaptoethanol demonstrated that 65 to 80% of the [5- (3)H]uridine-labeled molecules resided in the viral core. When the total nucleic acids were extracted from viral cores prepared from virions propagated in HeLa cells, 30 to 50% of the total incorporated [5- (3)H]uridine was found in RNA; in L mouse fibroblasts, 40 to 50%; in primary chicken embryo fibroblasts, 50 to 60%. The RNA molecules do not appear to be covalently linked to the viral DNA genome but sediment in sodium dodecyl sulfate-sucrose gradients as 8 to 10S species relative to ribosomal RNA.

Experience with simplified scheme of treatment of hyperlipidaemia. A series of 57 hyperlipidaemic patients have been investigated clinically and by measurement of cholesterol and triglyceride levels and inspection of stored serum. Two had secondary (alcoholic) hyperlipidaemia. Those with primary disorders were allocated to three groups believed to require different optimal therapy. At one year 51 of these 55 patients had lipid levels within a predetermined normal range and two others showed improvement. Despite the large number of primary hyperlipidaemic states our results suggest that in most patients successful treatment can be given according to simple classification into three therapeutic categories.

Extracellular polysaccharides of Actinomyces viscosus. Polysaccharide(s) have been isolated from supernatants of broth cultures of Actinomyces viscosus, strain T6. The organism produces significant quantities (2 mg/mg of cell [dry weight], 108 mg/liter) of this polysaccharide in the absence of sucrose. Chemical analysis indicated that N-acetylglucosamine (62%) was the major component; galactose (7%), glucose (4%), uronic acid (3%), and smaller amounts of glycerol, rhamnose, arabinose, and xylose were also present. The polysaccharide(s) is only slightly soluble in aqueous solutions. Although further purification of the polysaccharides will be necessary before definitive chemical and structural studies, the formation of extracellular polysaccharides is significant because it offers a possible explanation for plaque formation by these organisms.

Factor analysis of international cancer mortality data and per capita food consumption. It has long been recognized that international death rates for many cancer sites tend to be associated and are higher in the more "westernized" countries. The specific sites, with respect to cancer deaths among men, were identified in the present study through factor analysis of death rates by cancer site in 41 countries. Rates from the following cancer sites were found to be associated with a westernization factor: intestine, rectum, lung, skin, leukaemia and prostate.

Family planning method change and dropouts in the Philippines. Pregnancy prevention techniques are classified into 2 general categories as the coitus-connected and coitus-independent.  The former include rhythm, withdrawal, condom, and foam while the latter include such methods as oral contraception, IUDs, and male and female sterilization.  The use of contraception hinges on motivation and the acceptability of the method.  This article is a report on 1 particular study where data was collected in 1971-1972 through 1321 interviews resulting from a series of audits of family planning clinics with the purpose of determining the accuracy of information reported in  clinic records and ascertaining the number of acceptors who had discontinued use of a family planning method or moved from the area served by the clinic.  The findings revealed that: 1) Coitus-independent methods are more effective in the prevention of pregnancy that coitus-dependent ones, 2) Women who change from a coitus-dependent method are more likely to change to a coitus-independent  method, while the changes from the latter method are usually to a method in the same general category, 3) In this population the IUD provides the maximum protection from conception with the minimum likelihood of program dropout.

Fatty acids present in the lipopolysaccharide of Rhizobium trifolii. Approximately 70% of the fatty acids recovered after acid or alkaline hydrolysis of the lipopolysaccharide of Rhizobium trifolii were hydroxy fatty acids identified as hydroxymyristic and hydroxypalmitic acids. Palmitic acid was the only saturated fatty acid found in the lipopolysaccharide of R. trifolii. Octadecenoic and a small amount of hexadecenoic acids were also identified. The results of BF(3) methanolysis and hydroxylaminolysis suggest that hydroxypalmitic acid is N-acyl bound.

Flux of free fatty acids among host tissues, ascites fluid, and Ehrlich ascites carcinoma cells. The role of plasma free fatty acids (FFA) in the transport of fatty acids from host tissues to Ehrlich ascites carcinoma in mice was studied. [9,10-(3)H] Palmitate complexed to mouse serum (albumin) was injected either intraperitoneally or intravenously into unanesthetized tumor-bearing mice. The incorporation of radioactivity into tumor extracellular fluid FFA, tumor cell FFA, neutral lipid, phospholipid, water-soluble material in cells and fluid, plasma FFA, host carcass total lipid fatty acids, and water-soluble (i.e., nonlipid) material was measured. In addition, the quantity of fatty acid in each of the above lipid fractions was determined. The data were analyzed by multicompartmental analysis (SAAM) using a digital computer, and fractional rate constants of FA movement within and out of the host-tumor system were calculated. These rate constants and pool size measurements were used to estimate the corresponding fluxes. Although FFA in the tumor's extracellular fluid were replaced rapidly, almost none of the newly formed fluid FFA was derived from plasma FFA. Moreover, the transfer of FFA from the tumor extracellular fluid FFA to plasma FFA was virtually negligible. We suggest that the net amount of FFA required to replace the fluid FFA utilized for tumor energy and growth may be derived from direct transfer of FFA from host tissues to the ascitic fluid and that plasma FFA is not an intermediate in this transport process. The transport of FFA from the host to tumor cell lipids through the tumor extracellular fluid was about 26-fold greater than that required to account for net lipid accumulation during growth.

Freeze-fracture of microtubules and bridges in motile axostyles. A freeze-fracture study of the motile axostyles of the flagellate protozoa Saccinobaculus and Pyrsonympha has been undertaken in order to obtain a view of the relationships of microtubules and their cross bridges not dependent on conventional preparative procedures. Reactivation studies using isolated axostyles prepared for freeze-fracture and then thawed demonstrate that we are observing the structure of a potentially functional axostyle. Cross fractures through the axostyle demonstrate more extensive interrow bridging than expected on the basis of observations of thin-sectioned material. Each microtubule has approximately sixfold bridge-binding sites with connections to as many as four interrow bridges. Measurements of microtubule diameter and spacing are significantly larger than those made from sectioned material and may indicate that conventional processing for electron microscopy results in the loss of structurally important water within the microtubule in addition to loss of intertubule material. Longitudinal fractures through the axostyle at various orientations demonstrate a minimum longitudinal periodicity of 160 A for both the spacing of the globular subunits within the microtubule wall and the spacing of the intrarow bridges. While intrarow bridges are strictly periodic and always oriented in parallel, interrow bridges are not strictly periodic and can be oriented at varying angles to the microtubule axis.

Functional differentiation of human jejunum and ileum: a comparison of the handling of glucose, peptides, and amino acids. The characteristics of glucose, glycine, L-alanine, and glycyl-L-alanine absorption from the jejunum and ileum have been compared in normal human subjects. A perfusion technique has been used, and correct positioning of the perfusion tube has been confirmed by measuring the differential jejunal and ileal handling of bicarbonate. Glucose and glycine were absorbed faster from the jejunum than from the ileum of all subjects studied, and L-alanine was absorbed faster from the jejunum than from the ileum in five out of six subjects studied. In contrast, the dipeptide glycyl-L-alanine was absorbed at comparable rates from the jejunum and ileum. Higher concentrations of free amino acids were detected in the luminal contents aspirated during the ileal dipeptide perfusions.These results emphasize the importance of oligopeptide transport in the absorption of protein digestion products, especially in the human ileum, and the practical implications of these findings are discussed.

Functional studies of the parotid and pancreas glands in amyotrophic lateral sclerosis. Functional studies of the pancreas and parotid glands are reported in 17 patients with amyotrophic lateral sclerosis (ALS). The exocrine function of the pancreas was studied by measuring amylase concentration after stimulation with the endogenous secretin-pancreozymine test (ESP). Under these conditions, the pancreatic amylase concentration in ALS patients was found to be markedly decreased by about 45% when compared with those of healthy control subjects. Different conclusions in the literature about a possible impairment of the exocrine pancreas in ALS patients induced us to study the function of the parotid gland, which has close structural, functional, and physiopathological relationship with the pancreas. Flow rate and bicarbonate concentration of parotid saliva were measured after indirect stimulation (intraoral citric acid) and direct stimulation (pilocarpine). After indirect stimulation, both parotid flow rate and bicarbonate concentration from ALS patients were found to be decreased by about 66% and 70% respectively, when compared with controls. On the other hand, direct stimulation with pilocarpine in ALS patients elicited normal responses in both flow rate and bicarbonate concentration of saliva. It is concluded that the pancreatic and parotid deficiencies observed in ALS patients do not indicate primary disease of these exocrine glands. This interpretation is further emphasized by the results obtained by a sweat test, plasma osmolarity, and sialographic studies. The possibility that the gland impairments observed might be due to modifications of the neuroendocrine mechanisms regulating their secretory activity is suggested.

Further observations on the cardiotoxicity of isoprenaline during hypoxia. 1 In dogs respired with 10% oxygen: 90% nitrogen, only five out of 16 dogs survived repeated intravenous doses of isoprenaline (either 0.5 or 1.0 mug/kg) and only one out of six dogs survived repeated isoprenaline inhalations from a pressurized aerosol.2 In dogs respired with 15% oxygen: 85% nitrogen, five out of six dogs survived repeated intravenous doses of isoprenaline (2.5 mug/kg).3 The fatal response in these animals consisted of a fall in heart rate, arterial and pulse pressures. Sinus rhythm persisted even after the arterial pressure had fallen, though occasionally a slow A-V nodal rhythm or irregular ventricular ectopic beats occurred. Ventricular fibrillation did not occur.4 Eight out of 10 dogs brought to the verge of a fatal response with 10% oxygen: 90% nitrogen and repeated doses of isoprenaline (2.5 mug/kg) were resuscitated by the administration of 100% oxygen and, when necessary, cardiac massage.5 A group of five dogs survived the combined effects of repeated doses of isoprenaline (2.5 mug/kg) and respiration with 10% oxygen: 90% nitrogen when the time interval between doses was 11 min, instead of the usual 5 minutes.6 Control of pH by infusion of sodium bicarbonate did not protect the dogs from the combined effects of hypoxia and repeated isoprenaline challenge.7 After a 60 min period of continuous isoprenaline infusion in dogs breathing room air, only one of 10 dogs survived artificial respiration with 10% oxygen: 90% nitrogen and repeated challenge with intravenous isoprenaline (1.0 mug/kg) at 5 min intervals. At the higher infusion levels of isoprenaline (0.1 and 1.0 mug kg(-1) min(-1)), two dogs out of four died after the hypoxic mixture was started but before any isoprenaline challenge was given.8 The possible relevance of these findings in dogs to the recently observed increase in mortality in young asthmatics is discussed.

Gastrocutaneous fistula following radiation therapy for seminoma of the testis. A case presentation of a gastrocutaneous fistula following orthovoltage radiotherapy for prophylactic lymph node sterilization for seminoma of the testis is recorded. Many factors determine the response of an organ to radiation and with certain circumstances irreversible damage ensues. The pathologic effects of radiation on the stomach in the reported patient illustrates two stages of injury, acute and chronic. The insidious course of chronic injury eventually destroyed gastric and abdominal wall tissue to create a gastrocutaneous fistula 45 months after radiotherapy. Radiation therapy is a critical therapeutic modality in the treatment of neoplastic diseases and should be carefully administered with close followup of patients for acute and latent radiation effects.

Genetic analysis of Salmonella minnesota R mutants with defects in the biosynthesis of the lipopolysaccharide core. A set of R (rough) mutants, in which the synthesis of the cell wall lipopolysaccharide is defective, were analyzed genetically. These same Salmonella minnesota mutants have been used extensively in biochemical studies. By combining the information from all these studies, we obtained a complete genetic description of many of these mutants. Most of them turned out to be double rfe rfa mutants in which the rfe mutation (close to ilv) accounts for inability to synthesize O-specific structures and the rfa mutation accounts for defects in the synthesis of the core and, thus, for the lipopolysaccharide chemotype. These mutants demonstrate that in S. minnesota of O group L, as well as in S. typhimurium of the O group B, the rfb gene cluster close to his determines the synthesis of the O-specific side chain of the lipopolysaccharide, and the rfa genes in a cluster close to pyrE determine the synthesis of the lipopolysaccharide core. Phosphorylation of the core is determined by a rfaP gene also in this cluster and so far identified only by these S. minnesota mutants. In addition, the rfe gene(s) close to ilv is required for O-side chain synthesis in S. minnesota but not in S. typhimurium.

Glycoprotein synthesis and secretion by mucosal biopsies of rabbit colon and human rectum. Elucidation of mechanisms involved in the control of colonic production of mucus requires direct examination of glycoprotein synthesis and secretion by colonic mucosa. In the past, the limited viability of intestinal mucosa in vitro has hampered such investigations. When maintained in an organ culture system, mucosal biopsies of rabbit colon and human rectum remained viable for 24 h as documented by morphologic appearance and a steady rate of protein synthesis and secretion. These biopsies also incorporated (14)C-labeled glucosamine into tissue glycoproteins and secreted labeled glycoproteins at a steady rate for 24 h. Glucosamine was predominantly incorporated into macromolecules that were ultimately secreted, in contrast to leucine, which was predominantly incorporated into tissue macromolecules. When studied by autoradiography, cultured rabbit colonic biopsies synthesized and secreted glycoproteins in vitro at cellular sites and over a time-course similar to those previously described for the intestine of intact animals. Acetylcholine consistently stimulated secretion of labeled glycoproteins but did not alter glycoprotein synthesis. In contrast, cycloheximide inhibited glycoprotein synthesis but had no effect on the secretion of newly synthesized glycoproteins. Rectal biopsies from patients with active ulcerative colitis incorporated increased amounts of [(14)C]glucosamine into glycoproteins during organ culture and secreted labeled glycoproteins more rapidly into the incubation medium when compared to biopsies obtained from healthy volunteers These findings indicate that organ culture provides a useful means of directly examining the synthesis and secretion of glycoproteins by healthy and diseased colonic mucosa.

Glycoproteins of Sindbis virus: priliminary characterization of the oligosaccharides. The carbohydrate content of Sindbis virus was determined by gas chromatographic analysis. The two viral glycoproteins were found to be approximately 8% carbohydrate by weight. Mannose is the sugar present in the largest amount. Smaller amounts of glucosamine, galactose, sialic acid, and fucose were also detected. Each of the two viral glycoproteins appears to contain two structurally unrelated oligosaccharides. Two of the three Sindbis-specific glycoproteins found in infected chick cells were shown to contain short, unfinished oligosaccharides.

Glycosidases in normal and dimethylhydrazine-treated rats and mice with special reference to the colonic tumours. Activities of 12 glycosidases and of β-D-glucuronidase were measured in liver, kidney and in the gastrointestinal tract of rats and mice. The activities of different enzymes varied not only within one tissue but also among different tissues. In rats injected with 1,2-dimethylhydrazine, a many fold increase in N-acetyl-β-D-glucosaminidase, N-acetyl-β-D-galactosaminidase, β-D-galactosidase and α-L-fucosidase was found in colonic tumours and colonic mucosa. These enzymes were elevated significantly in the kidney of tumour bearing animals as well. Liver and other parts of the gastrointestinal tract showed an increase only in N-acetyl-hexosaminidase with the appearance of colonic tumours. In treated mice, 2 N-acetylhexosaminidases were elevated in colon, duodenum, liver and kidney. However, in liver and kidney, β-D-galactosidase was also significantly increased.

Growth rates of a pseudomonad on 2,4-dichlorophenoxyacetic acid and 2,4-dichlorophenol. The growth of a pseudomonad on 2,4-D (2,4-dichlorophenoxyacetic acid) and 2,4-DCP (2,4-dichlorophenol) was studied in batch and continuous culture. The optimum growth rate using 2,4-D was 0.14/h at 25 C in a pH range from 6.2 to 6.9. Highest specific growth rate using 2,4-DCP was 0.12/h at 25 C in a pH range from 7.1 to 7.8. Growth was strongly inhibited by 2,4-DCP above a concentration of 25 mg/liter whereas no appreciable inhibition was observed with 2,4-D at concentrations up to 2,000 mg per liter. Growth on 2,4-DCP was described by Monod kinetics at subinhibitory concentrations but the inhibition by 2,4-DCP exhibited an unusual linear response to substrate concentration, and did not fit a model based on noncompetitive inhibition. The lag phase of batch cultures was found to depend on both 2,4-DCP concentration and prior adaptation of the inoculum. A study such as this on the kinetics of growth on related substrates may be useful as a method of finding the rate-limiting step in a metabolic sequence.

Halophilic nuclease from a moderately halophilic Micrococcus varians. The moderately halophilic bacterium Micrococcus varians, isolated from soy sauce mash, produced extracellular nuclease when cultivated aerobically in media containing 1 to 4 M NaCl or KCl. The enzyme, purified to an electrophoretically homogeneous state, had both ribonuclease and deoxyribonuclease activities. The nuclease had maximal activity in the presence of 2.9 M NaCl or 2.1 M KCl at 40 C. The enzymatic activity was lost by dialysis against low-salt buffer, whereas when the inactivated enzyme was dialyzed against 3.4 M NaCl buffer as much as 77% of the initial activity could be restored.

Healing of the canine aorta after endarterectomy: a scanning electron microscopy study. Endarterectomy sections of canine aorta were examined in various stages of healing by scanning electron microscopy. In all specimens the endarterectomy site was quickly covered by a thin fibrin-platelet coagulum with varying amounts of thrombus. Neoendothelization began before one week and was virtually completed by one month except on areas of heavy thrombus deposition. While this study does not prove the origin of the neoendothelial cell, it suggests that neoendothelial cells are derived from pre-existing endothelium and advance over the endarterectomy site from the junction zone of the normal aorta and to a lesser extent from the orifices of brancing vessels.

Heterogeneity in lipid composition of the outer membrane and cytoplasmic membrane and cytoplasmic membrane of Pseudomonas BAL-31. The outer membranes and cytoplasmic membranes of the marine bacterium Pseudomonas BAL-31 were separated by washing the cells three times in 0.5 M NaCl and twice in 0.5 M sucrose. Electron microscopy during the removal of membranes revealed that the outer membranes fragmented in a regular manner to give rise to fairly uniform vesicles measuring approximately 140 nm in diameter. Isolated outer membranes had a buoyant density in sucrose of 1.230 g per cm(3), whereas the cytoplasmic membranes had a density of 1.194 g per cm(3). The removal of the outer membrane during the application of this procedure was monitored by measuring the release of 2-keto-3-deoxyoctulosonic acid and phospholipid. The cells lost 85.5% of their 2-keto-3-deoxyoctulosonic acid and 47.3% of their phospholipid during this treatment. Complete recovery of outer membrane material could be achieved. The removal of 25.5% of the 2-keto-3-deoxyoctulosonic acid and 0.9% of the phospholipid rendered the cells sensitive to lysis with Triton X-100. The phospholipid composition of the outer membrane was calculated to be 78.9% phosphatidylethanolamine and 16.1% phosphatidylglycerol. The phospholipid composition of the cytoplasmic membrane proved to be 71.5% phosphatidylethanolamine and 23.5% phosphatidylglycerol. The fatty acid composition was also found to be quantitatively heterogeneous between the two membranes.

Hippocampal electrical activity and different types of conditioned reflexes in dogs. Changes in hippocampal activity and heart rate were studied in dogs during elaboration of defensive and alimentary conditioned reflexes and switching-over between different types of reinforcement. Conditional stimuli enhanced synchronization and increased frequency of theta wave trains in hippocampal electrical activity. Parallelly to emotional tension of the dogs a significant rise in amplitude of integrated theta rhythm appeared. An increase in the positive correlation between the changes in amplitude of integrated theta rhythm and in heart rate shows that the hippocampal theta rhythm may be used as a correlate of emotional tension. Changes in hippocampal electrical activity in the early stages of formation of conditioned connections and throughout the experiment with conditioned "switching-over" suggest that emotional tension arises under conditions of pragmatic uncertainty when the animal does not have sufficient information for the organization of adaptive reactions. Mom marked changes in heart rate and in amplitude of hippocampal theta rhythm during the elaboration of defensive CRs compared with those observed during the development of response eliminating nociceptive stimulation of partner, suggest that the magnitude of emotional tension depends on the conditioned excitation underlying the response being elaborated.

Histologic changes in the seminiferous tubules after vasectomy. 4 different studies on the effect of vasectomy on the testis in canines and humans are reported.  Testicular biopsies were performed at certain intervals and the results in both humans and dogs were nearly identical.  It was found that spermatogenesis 2 to 3 weeks after vasectomy remained unchanged with accumulation of spermatozoa in the tubules.  Between 3 and 6 weeks, progressive spermatogenic arrest with few spermatozoa and decreased spermatids were observed.  Between 100 and 300 days, occasional mature sperm were found in the tubules indicating a return of spermatogenesis.  Meiotic studies showed this to be an arrest in early prophase.  It is theorized that spermatogenesis may be sensitive to pressure changes in the tubular system.

Home accidents to children under 15 years: survey of 910 cases. Out of 910 accidents sustained by children under 15 seen at the casualty department of a local hospital 678 (74.5%) were to children under 5 years of age. Boys were more prone to accidents than girls, and in preschool children the highest incidence of accidents was among the 2-to 3-year-olds of both sexes. Social class had no significant bearing on the accident rate. The fact that the average size of families with children under 5 was higher among families living in council houses than among those living in private houses appeared to have some bearing on the higher incidence of accidents among children under 5 living in council houses. There appeared to be no peak month when accidents were more frequent and the incidence of accidents was not significantly high on any particular weekday. In 95% of the cases one or both parents were in charge of the child at the time of the accident.Cuts were the most common types of accident followed by falls and poisoning. Among other accidents crushed fingers were as frequent as burns. A total of 62 patients (6.8% of all cases) were admitted as inpatients. Of the actual causes of the cuts and falls playing, fighting, and misbehaving were the most common followed by falling from beds, chairs, etc. While there is a need for health education programmes to draw attention to the specific dangers evidenced there clearly will always be home accidents.

Human milk lipases. I. Serum-stimulated lipase. Lipase activity has previously been demonstrated in human milk. This study shows that there are two separate triglyceride lipases in human milk. One is mainly in the skim milk and is stimulated by bile salts; the other is mainly in the cream and is inhibited by bile salts but stimulated by serum. The serum-stimulated lipase was purified by affinity chromatography on heparin-substituted Sepharose 4B. This gave a 9500-fold purification over whole milk. Although polyacrylamide gel electrophoresis showed that the enzyme was not purified to homogeneity, it had the highest specific activity so far reported for a human serum-stimulated lipase. The purified enzyme was free from bile salt-stimulated lipase activity and had the characteristics of other serum-stimulated or so-called lipoprotein lipases. Thus, it was almost completely inhibited by 1 M NaCl. The purified enzyme was active against tributyrylglycerol also in the absence of exogenous serum factors.

Human puberty. Simultaneous augmented secretion of luteinizing hormone and testosterone during sleep. Plasma luteinizing hormone (LH) and testosterone (T) were measured by radioimmunoassay in nine pubertal boys and three sexually mature young men at 20-min intervals for 24 h. Plasma LH and T were also measured in one boy during a delayed sleep onset study. Polygraphic monitoring was carried out to identify precisely sleep onset. Wakefulness, and specific sleep stages. In all nine pubertal boys the plasma T concentration fluctuated and was significantly higher during normal nocturnal sleep as compared to daytime waking. This increased T secretion during sleep was temporally linked to the characteristic pubertal sleep augmentation of LH secretion. To define further the relationship of this increased T secretion to sleep, plasma LH and T were also measured in three of the pubertal boys after acute (1-day) reversal of the sleep-wake cycle. One of these boys was also studied after 3 days of sleep-wake cycle reversal. The results of these studies showed that plasma T was now augmented during the reversed daytime sleep period; the mean T concentrations during this period were significantly higher (P < 0.001) than during nocturnal waking in all four studies. Measurement of plasma LH and T in the three sexually mature young men showed episodic secretion of LH and T during both waking and sleep periods; there was no consistent significant augmentation of LH or T secretion during sleep. This study demonstrates that (a) in normal pubertal boys and sexually mature young men plasma T fluctuates episodically; (b) there is marked augmentation of T secretion during sleep in pubertal boys, which is dependent on increased LH secretion; (c) this pubertal LH-T secretory "program" is dependent on sleep, since it shifts with delayed sleep onset and reversal of the sleep-wake cycle; and (d) this demonstrable tropic effect of LH on T is evident only during puberty, since sexually mature young men fail to show any consistent relationship between LH and T secretion either awake or asleep.

Hydrocarbon metabolism by Brevibacterium erythrogenes: normal and branched alkanes. Branched- and straight-chain alkanes are metabolized by Brevibacterium erythrogenes by means of two distinct pathways. Normal alkanes (e.g., n-pentadecane) are degraded, after terminal oxidation, by the beta-oxidation system operational in fatty acid catabolism. Branched alkanes like pristane (2,6,10,14-tetramethylpentadecane) and 2-methylundecane are degraded as dicarboxylic acids, which also undergo beta-oxidation. Pristane-derived intermediates are observed to accumulate, with time, as a series of dicarboxylic acids. This dicarboxylic acid pathway is not observed in the presence of normal alkanes. Release of (14)CO(2) from [1-(14)C]pristane is delayed, or entirely inhibited, in the presence of n-hexadecane, whereas CO(2) release from n-hexadecane remains unaffected. These results suggest an inducible dicarboxylic acid pathway for degradation of branched-chain alkanes.

Incomplete and aberrant particles of actinophage MSP2 from lysates of Streptomyces venezuelae. Lysates of actinophage MSP2, propagated on Streptomyces venezuelae S13, contain at least 10(11) PFU/ml. During purification by centrifugation methods and by adsorption chromatography, a number of types of aberrant and incomplete phage particles were seen by electron microscopy. Infectious MSP2 had a buoyant density in CsCl of 1.52 g/cm(3) and an absorbance at 260 nm relative to that at 280 nm (A(260)/A(280)) of 1.53. Empty capsids banded at 1.276 g/cm(3) and partially filled capsids banded at 1.351 g/cm(3), and A(260)/A(280) ratios were 0.77 and 1.24, respectively. Two kinds of light capsids found in CsCl fractions of 1.278 g/cm(3) probably include the 1.276 component. Some capsids were joined by tail-like structures. Ghosts and polyheads also were present. Aberrant particles observed by electron microscopy included two-tailed actinophage, phage with abnormal tail positions, and large-headed phage.

Indentification of an intestinal sodium and calcium-dependent phosphatase stimulated by parathyroid hormone. Previous reports suggest that the site of the energy-dependent intestinal calcium transport against an electropotential and concentration gradient is located along the basal-lateral membrane of the mucosal cell. Accordingly, basal-lateral membranes were prepared from rat intestinal homogenates in order to identify the enzyme mediating this step in the transport process. An alkaline phosphatase was delineated which utilized ATP as a substrate and was dependent on both Na(-) and Ca(++) with optimum enzyme activity at 200 mM and 0.04 mM, respectively. Furthermore, the activity of the enzyme was demonstrated to decrease with the advance in age of the animal and to decrease with removal of the parathyroid glands, consistent with a decreased rate of (45)Ca release from mucosal cells under the same experimental conditions. Calcium binding to basal-lateral membrane fragments was also sodium dependent and enhanced by the prior administration of parathyroid extract. The consistent correlation between the rate of calcium transport across the basal-lateral membrane of the mucosal cell and the activity of this Na, Ca-dependent phosphatase under a variety of experimental conditions suggest that this enzyme may mediate the parathyroid hormone-sensitive active transport of calcium across the intestine.

Influence of oral contraception on cytology and histology of the cervix uteri. Population screening for cervical carcinoma in Maribo amt 1967-1969. In this study women using oral contraceptives were compared with those using other contraceptive methods with regard to abnormal cytologic findings of the cervix uteri.  13,125 women were studied, of whom 1471 had used oral contraceptives for an average of 24 months.  In 446 women cytologic findings were abnormal; frequency did not differ significantly betweeen users and nonusers of oral contraception.  Epithelial dysplasia was found in 69 cases, carcinoma in situ in 236, invasive carcinoma in 45, trichomoniasis in 32, and simple epithelial hyperplasia in 44.  No significant difference was found in any group between users and nonusers of oral contraceptives.  Classifications as to age, marital status, number of pregnancies, or age at first pregnancy showed similar ratios between users and nonusers.  The only variation noted was that women of the middle socioeconomic class had abnormal findings in 4.9% of users compared to 2.8% of nonusers.  It was concluded that use of oral contraceptives for an average of 24 months produces no change in the frequency of any abnormal cytologic findings in the cervix uteri.

Influence of sodium and parathyroid hormone on calcium release from intestinal mucosal cells. The uptake and release of (45)Ca from the intestinal mucosal epithelium were investigated under a variety of conditions. The initial rate of uptake characterized a calcium pool with a half-time of saturation of less than 2 min. The entry of (45)Ca into this pool was inhibited by NaCN and ethacrynic acid and was stimulated by the removal of Cl(-) from the incubation. The initial rate of (45)Ca release was also inhibited by NaCN and removal of Na(+) from the incubation. Parathyroid hormone administration enhanced the release of (45)Ca from cells prepared from parathyroid-ectomized animals. These observations suggest that calcium transport across the brush border and basallateral membranes are identifiable components of the kinetics of (45)Ca uptake and release and that parathyroid hormone stimulates a sodium-dependent mechanism of calcium transport across the basal-lateral membranes.

Inhibition of cellular DNA synthesis in cells infected with infectious pancreatic necrosis virus. In asynchronous RTG-2 cell cultures infected with infectious pancreatic necrosis (IPN) virus, inhibition of cellular DNA synthesis, but not protein synthesis, was detected 5 to 6 h postinfection and was 80 to 90% complete by 7 to 8 h. Inhibition of DNA synthesis was largely abolished by UV irradiation of the virus. Sedimentation analyses of phenol-extracted DNA indicated that native cellular DNA was not degraded during infection. Sedimentation on alkaline sucrose gradients of DNA from cells pulsed with radioactive thymidine for varying periods indicated that elongation of nascent DNA chains proceeded normally in infected cells. These and previous results suggest that IPN virus infection results in a reduction of the number of chromosomal sites active in DNA synthesis but does not affect the rate of polymerization at active sites. Cells synchronized with excess thymidine and hydroxyurea and infected with virus at the time of release from the block demonstrated an inhibition of DNA synthesis 3 h postinfection. Cells infected 4 h prior to release continued to synthesize normal amounts of DNA for 1 to 2 h after release. These results indicated that DNA synthesis in early synthetic phase is relatively insensitive to inhibition by IPN virus.
