The effect of cortisol on the haematocrit values and serum electrolytes of the adult and foetal rat. 1. The serum sodium, potassium and chloride levels of the non-pregnant rat, pregnant rat and foetus were estimated under normal circumstances and following the administration of 3 mg/kg cortisol to the non-pregnant and pregnant rat.2. Normally, the electrolytes and haematocrit value of the non-pregnant rat and the electrolytes of the foetus were higher than those occurring in the pregnant rat.3. After treatment with cortisol, the sodium, potassium and chloride content of the serum, and the haematocrit value of the non-pregnant rat dropped significantly. There was no change in these values in the pregnant animals, but the foetus showed a significant decrease in sodium, potassium and chloride levels after maternal treatment.


Questions for a theory of cognitive development.


The chemical and energetic properties of muscles poisoned with fluorodinitrobenzene. 1. The heat production and mechanical responses of frogs' sartorii have been recorded at 0 degrees C after immersion in normal Ringer solution, and also after poisoning with 1-fluoro-2, 4-dinitrobenzene (FDNB) and nitrogen. The muscles were later analysed chemically for changes in ATP, phosphocreatine (PC), inorganic phosphate (P(i)), lactate, total adenine nucleotide and total inosine nucleotide.2. Analysis of paired resting muscles established that the resting levels of these substances found in our experiments were similar to those reported elsewhere.3. Resting muscles that had been poisoned with FDNB and N(2) contained significantly more PC and less ATP than unpoisoned controls. Moreover, some of their adenine had been deaminated to inosine.4. In a normal muscle in oxygen, the PC that breaks down as a result of a 30 sec tetanus is restored with a roughly exponential time course whose half-time is about 10 min. Thus at least 40 min rest must be allowed between the different stages of an experiment.5. Isometric twitches of the poisoned muscle rapidly decline in size, but small twitches continue to be produced for a very long time. If stimulation is discontinued, substantial recovery takes place. The total tension development is equivalent to at least thirty normal twitches, and correspondingly, the total heat production is greater than could be accounted for even by complete break-down of the ATP in the muscle. In fact, the ATP break-down, though highly significant, is not nearly complete.6. In short series of isometric twitches there is significant break-down of ATP and, less consistently, of PC; also a significant increase in P(i) but no additional deamination of adenine. The rate of development of isometric tension is slightly decreased.7. The results described under (6) are definitely due to the presence of FDNB. In similar experiments with the muscles in N(2) but not otherwise poisoned the only significant change is a break-down of PC.8. In a long series of isotonic twitches the chemical effects are similar to those described under (5) and inosine formation is clearly demonstrable. The poisoned muscles show force-velocity curves of normal shape, the Fenn effect and the presence of shortening heat. Thus their contractions are normal or nearly so.9. The complexity of the chemical reactions that continue in the poisoned muscle makes it impossible to draw up an accurate energetic balance sheet.10. A new hypothesis is suggested to explain the energetic importance of inosine formation.


Effects of arterial hypoxia on the cutaneous circulation of the rabbit. 1. Changes in blood flow of the skin of the rabbit's ear and hind limb have been studied during arterial hypoxia by a calibrated heat conductivity method, together with changes in arterial pressure and aortic blood temperature.2. There is little change in the blood flow of the hind-limb skin during the early phase of arterial hypoxia, reflecting a balance between the local dilator effects of hypoxia and the increased constrictor activity mediated through the sympathetic nerves as a result of arterial chemoreceptor excitation. During more prolonged arterial hypoxia there is a small gradual dilatation of the vessels of the hind-limb skin as a result of some diminution in the initial intensity of vasoconstrictor activity.3. There is much more extensive vasodilatation in the ear than in the hind-limb skin during arterial hypoxia. Vasoconstrictor activity is slight in this region. Comparison of the ear responses to arterial and to primary tissue hypoxia suggests that in the former type of hypoxia stimulation of the arterial chemoreceptors inhibits thermoregulatory vasoconstriction to the ear, whilst in the latter type of hypoxia baroreceptor reflexes maintain or intensify it.

Purification and general properties of aspartate aminotransferase of ox heart. 1. A five-step procedure for preparing highly purified aspartate aminotransferase from ox heart is described. 2. The homogeneity of the pure enzyme was established by criteria such as ultracentrifugation and electrophoresis in starch gel and in polyacrylamide gel. 3. The pure enzyme has an isoelectric point of about pH5, and E(1%) (1cm.) 14.40 at 278mmu. 4. The molecular weight of the pure enzyme was determined as 96000 by sedimentation equilibrium. 5. The pH optimum for the pure enzyme was about 8. It was determined by a new assay technique. 6. A difference in the electrophoretic migration rate between the enzyme from ox heart and brain and the enzyme from pig heart and brain suggests a species specificity rather than an organ specificity. 7. A new effect of deionization on the visible-absorption spectrum of the enzyme was observed.


Amino acid composition and terminal residues of aspartate aminotransferase from ox heart. 1. The amino acid composition of highly purified aspartate aminotransferase from ox heart was determined. 2. Alanine is the only N-terminal residue. 3. Leucine was identified as the only C-terminal residue. 4. No disulphide bridges are present in the enzyme molecule. 5. The thiol groups are not equally accessible, the accessibility being comparatively easier in the apoenzyme molecule.


Stimulation by insulin of the formation of ribonucleic acid and protein by mammary tissues in vitro. 1. Insulin is one of the hormones that are essential for successful tissue culture of explants of the mammary glands of pregnant mice. We report here effects of insulin on RNA and protein formation by mammary tissue from pregnant mice and rats incubated in tissue-culture medium 199. 2. The incorporation of [(14)C]adenine over 3hr. into the RNA of explants of the mammary glands of pregnant mice was increased by an average of 68% when the medium contained 5mug. of insulin/ml. Under similar conditions the incorporation into the RNA of slices of the glands of pregnant rats was increased by an average of 61%. Incorporation into the RNA of slices from lactating rats was stimulated to a smaller extent. 3. Adipose tissue was separated from the glands of pregnant mice and the effect of insulin on the incorporation of adenine into its RNA was studied. In whole explants the incorporation of adenine, both with and without insulin, is almost entirely into the RNA of the mammary parenchyma and not of the adipose tissue. 4. Insulin also stimulated by 38% the incorporation of [(14)C]leucine over 3hr. into the proteins of slices of the glands of pregnant rats. It had no significant effect on slices from lactating rats. 5. Actinomycin D (10mug./ml.) decreased the incorporation of [(14)C]adenine into the RNA of slices of the glands of pregnant rats by an average of 97%. Though it also decreased the incorporation of [(14)C]leucine into the proteins by an average of 25%, the percentage stimulation by insulin of this incorporation remained unchanged.

Studies of the congenitally goitrous sheep. Composition and metabolism of goitrous thyroid tissue. 1. Normal and congenitally goitrous thyroid tissue was examined to identify the defective mechanism in the goitrous glands. 2. The uptake of [(131)I]iodide from the blood stream into the goitrous glands (average 74.9%) was significantly greater than normal (average 43.5%; P < 0.005), as was the rate of [(131)I]iodide release (goitrous t((1/2)) average 72.3hr., normal t((1/2)) average 198.7hr.; P0.025). 3. The l-[(131)I]-iodotyrosine-deiodinase activity was significantly (P0.02) greater than normal in goitrous-thyroid slices. 4. The 0.9%-sodium chloride-soluble proteins of [(131)I]-iodide-labelled thyroid glands were fractionated with ammonium sulphate: 68.7+/-4.0% of the total radioactivity appeared in the 35-45%-saturation precipitate from normal gland extracts, but less than 20% of the total radioactivity was in in this fraction from goitre extracts. 5. Ultracentrifugal analysis of 0.9%-sodium chloride-soluble proteins of goitrous glands showed no protein of S(20,w) 19-20s (thyroglobulin) even when the animals had previously received 0.1-2.0mg. of l-thyroxine/day intramuscularly for 40 days. The major proteins of goitrous glands had S(20,w) 3.2-7.6s. 6. The incorporation in incubated slices of [(14)C]proline and [(14)C]leucine into soluble proteins precipitated by 35-42%-saturated ammonium sulphate was markedly lower in goitrous tissue. 7. It was concluded that the goitrous tissue exhibited defective biosynthesis of thyroglobulin.


Proteins of the succus entericus from the jejunum of the sheep. 1. Suitable methods for studying the proteins passing into the small intestine are discussed. 2. The proteins passing into temporarily isolated jejunal loops between double re-entrant fistulae in four sheep were studied. 3. Loops about 60-70cm. long secreted protein at a rate of 1-5g./24hr. The effect of slight stimulation of secretion by air pressure on the output of protein in 24hr. was not regular. The total protein in the fluid part of the succus entericus is about 2(1/2) times the serum albumin content of the fluid. 4. The additional protein contained in the cellular debris amounts to about 60% of the protein in the fluid part of the succus entericus. 5. Comparison of the proteins in succus entericus with those in serum by immunoelectrophoretic and other electrophoretic methods showed eight components in the fluid part of the succus entericus that appeared to be the same as those in serum and two components that appeared not to be present in serum. 6. Thin-layer gel chromatography in Sephadex G-200 and sedimentation analysis showed that the succus entericus contained two proteins not present in serum, one with sedimentation coefficient (uncorrected) 10s and one sedimenting slower than albumin: they move with the macroglobulin and slower than albumin respectively on gel chromatography. 7. These proteins could be secreted by the glandular epithelium of the small intestine or liberated from desquamated epithelial cells.


Amino acid incorporation by cell fractions from the oviduct of the laying hen and the synthesis of egg-white proteins. 1. Homogenates of the magnum of the hen oviduct have been fractionated by differential centrifuging. 2. Centrifuging at 600g for 10min. gave a pellet containing most of the particulate material of the cell, but on washing this fraction some particles were removed from it. The washed 600g pellet contained most of the DNA of the homogenate. 3. Centrifuging the 600g supernatants at 10000g for 10min. gave particulate fractions (I particles) richer in RNA than other fractions which were active in incorporating amino acids into protein in isolation. When minced tissue was incubated with radioactive amino acids before homogenizing these particles were the most radioactive of the cell fractions. 4. The pellet obtained by centrifuging the 10000g supernatant at 105000g for 60min. was very small; its RNA/protein ratio was raised compared with that of the homogenate. It only incorporated amino acids in isolation to a small extent or not at all. 5. The 105000g supernatant contained a large proportion of the protein of the homogenate. 6. The I particles could be subfractionated by layering over denser sucrose to give a pellet with lower RNA content and incorporating activity, and also suspended material richer in both these properties. 7. Treatment of the I particles with deoxycholate gave rise to particles sedimenting at 105000g for 60min. containing most of the RNA of the original particles, but only about 34% of the protein, and with a high activity in incorporating amino acids. 8. The I particles, or particles derived from them by deoxycholate treatment, required GTP and phosphoenolpyruvate for the incorporation of free amino acids. The omission of ATP reduced the incorporation to varying extents. Chicken-liver cell sap stimulated the activity. 9. Radioactive amino acids linked to transfer RNA were transferred to protein by I particles. GTP and phosphoenolpyruvate were required for this transfer. The phosphoenolpyruvate requirement could not be replaced by increasing the GTP concentration. ATP partially inhibited the transfer. 10. After incorporation by the cell-free system, the hot-trichloroacetic acid extract, but not the lipid extract, was radioactive. Ribonuclease and puromycin inhibited at low concentrations. Lecithinase-C was much less inhibitory. Transfer of amino acid, from a radioactive lipid-amino acid complex prepared from hen oviduct, was not detected. 11. After short periods of incubation of minced tissue with [(14)C]lysine some of the radioactive protein of the isolated I particles behaved as ovalbumin. The distribution of radioactivity in the protein resembled that in ovalbumin in soluble extracts of the tissue obtained after longer periods of incubation.

Inhibition of cholinesterases by fluoride in vitro. 1. Series of colorimetric dynamic assays allowed the study of the inhibition of cholinesterases by F(-) ions in vitro, by using, as sources of enzyme, whole human blood, human serum, homogenized rat brain and two preparations of red blood cells (human and bovine) whose enzymic purity was ascertained. 2. The first evidence of inhibition of human serum pseudocholinesterase by fluoride was noticed at 15-25mum-fluoride. Ten times as much fluoride was needed to start inhibition of acetylcholinesterase of the red blood cells. 3. The action of fluoride on the enzymic reaction was immediate. The reversibility of the inhibition was shown by dialysis and dilution. 4. Kinetic measurements showed that the inhibition under study was not dependent on the substrate concentration and was of the uncompetitive type, similar to that observed in the presence of a heavy metal (cadmium). 5. The activity of serum cholinesterase did not change in the absence of Mg(2+) and Ca(2+) ions. Fluoride was shown to inhibit the enzyme in the absence of these ions as well as of phosphate. 6. Fluoride could inhibit cholinesterases in the presence of three different substrates and had no action on the non-enzymic hydrolysis. 7. It is thought that the halide is bound reversibly to the enzyme molecule, with the probable exclusion of the active site, but no firm conclusion could be reached on this point.


The effect of vitamin A deficiency on the biosynthesis of steroid hormones in rats. 1. The synthesis, both in vivo and in vitro, of various steroid hormones in the adrenals, testes and ovaries of rats was compared at various stages of vitamin A deficiency with the corresponding pair-fed controls. 2. The enzymic conversion of the Delta(5)-3beta-hydroxy steroids into the corresponding Delta(4)-3-oxo steroids was significantly decreased in these tissues even at the mild-deficiency stage, further loss taking place on prolonging the deficiency. 3. In all three tissues the loss in the production of androstenedione from dehydroepiandrosterone could be reactivated in vitro by retinol or retinoic acid, but only at the mild stage of the deficiency. 4. Of the various lipoidal materials tried, retinal, retinol, retinoic acid, alpha-tocopherol acetate, menadione, calciferol, lecithin, palmitic acid and cholesterol, only retinol and retinoic acid restored the lost activity. 5. Intraperitoneal injection of retinal, retinol or retinoic acid into the deficient rats, 24hr. before they were killed, corrected the effect of the deficiency on this reaction. 6. Vitamin A deficiency markedly affected the synthesis of deoxycorticosterone and corticosterone from pregnenolone in the adrenals of rats, even at the mildly deficient stage, with further loss taking place at the acute stage; in vitro, retinol or retinoic acid could restore the loss at the mild-deficiency but not at the acute-deficiency stage. 7. The deficiency had no such effect on the synthesis of deoxycorticosterone from progesterone or of corticosterone from progesterone or deoxycorticosterone. 8. Compared with the pair-fed normals, the adrenals of deficient rats contained smaller amounts of deoxycorticosterone and corticosterone.


The use of fluorine-containing carboxylic acids for the large-scale isolation of highly polymerized deoxyribonucleic acids. 1. The precipitation of the proteins of calf-thymus nucleohistone and herringsperm nucleoprotamine with the salts of fluorine-containing carboxylic acids has been studied. Pentadecafluoro-octanoate gave a precipitate that could be sedimented almost completely by centrifuging at 2350g for 20min. omega-H-Hexadecafluorononanoate, omega-H-eicosafluoro-undecanoate and dodecyl sulphate gave precipitates that could only be partly sedimented under these conditions. 2. A method has been developed for the isolation of highly polymerized DNA on a large scale from calf thymus and herring sperm by the use of pentadecafluorooctanoate. This is more convenient and less tedious than existing methods.

Utilization of free fatty acids by starved and pregnant sheep. 1. The rate of entry into the plasma of stearic acid in fed and starved non-pregnant sheep and of palmitic acid in fed and starved pregnant sheep has been measured by a continuous-infusion isotope-dilution method. 2. In non-pregnant sheep the entry rate of stearic acid rose from 0.38mg./min./kg. when fed to 0.69mg./min./kg. after 72hr. starvation. In pregnant sheep, the entry rate of palmitic acid rose from 0.55mg./min./kg. when fed to 0.64mg./min./kg. on starvation. 3. The entry rates of palmitic acid and stearic acid are related to their respective plasma concentrations. 4. At a given plasma concentration the entry rate of palmitic acid in pregnant sheep was greater than that of stearic acid in non-pregnant sheep. 5. There was no detectable conversion of palmitate or stearate into other plasma long-chain fatty acids. There was negligible incorporation of fatty acids into other plasma lipids with the exception of the plasma triglycerides of fed pregnant sheep. 6. Up to 12% of expired carbon dioxide was derived from palmitic acid or stearic acid. The high rate of oxidation of plasma palmitic acid in fed pregnant sheep is noteworthy.

Effect of N,N' -bis(dichloroacetyl)-1,8-octamethylenediamine on the chemical composition of the rat seminiferous tubules. The effect of N,N'-bis(dichloroacetyl)-1,8-octamethylenediamine on the chemical composition of the rat seminiferous tubules was investigated.  Daily oral administration of 62.5 mg/kg for 21 days significantly reduced testis weight (p less than .01), protein nitrogen and enzyme activity of the tubules (p less than .01), increased tubal concentration of ribonucleic acid by 33%,  glycogen by 56%, lactic acid by 1406%, and ascorbic acid by 34% and reduced oxygen consumption rate by 32% and bicarbonate by 21%.  A total inhibition of hyaluronidase activity occurred.  It is concluded that this compound causes metabolic disturbance in the rat seminiferous tubules of an amplitude adequate to stop spermatogenesis.


The effect of calcium ions on the glycolytic activity of Ehrlich ascites-tumour cells. 1. Added Ca(2+) inhibited lactate formation from sugar phosphates by intact Ehrlich ascites-tumour cells. Lactate formation from glucose by these cells was unaffected by added Ca(2+). 2. The Ca(2+) inhibition of lactate formation by intact cells occurred in the extracellular medium. 3. Intact ascites-tumour cells did not take up Ca(2+)in vitro. 4. Glycolysis of sugar phosphates by cell extracts as well as pyruvate formation from 3-phosphoglycerate and phosphoenolpyruvate was inhibited by Ca(2+). 5. It was concluded that Ca(2+) inhibited the pyruvate-kinase (EC 2.7.1.40) reaction. Further, Ca(2+) inhibition of pyruvate kinase could be correlated with the overall inhibition of glycolysis. 6. Concentrations of Ca(2+) usually present in Krebs-Ringer buffers, inhibited glycolysis and pyruvate-kinase activity by approx. 50%. 7. The inhibition of glycolysis by added Ca(2+) could be partially reversed by K(+) and completely reversed by Mg(2+) or by stoicheiometric amounts of EDTA. 8. The hypothesis is advanced that the inability of tumour cells to take up Ca(2+) is a factor contributing towards their high rate of glycolysis.

Some observations on the fine structure of the lutein cells of x-irradiated rat ovary. The ovaries of 10- to 13-week-old rats were exteriorized and irradiated with sterilizing doses of X-rays. Following treatment, the animals entered a phase of constant vaginal cornification. Animals were killed 8 to 12 wk after the onset of this phase, and their ovaries were prepared for electron microscopy. Tissue was fixed in glutaraldehyde, postfixed in osmium tetroxide (Millonig's, phosphate-buffered), and embedded in Epon. Lutein cells from these ovaries were compared with those from sham-irradiated controls. The cytoplasm of lutein cells from experimental animals was characterized by an increase in the amount of agranular endoplasmic reticulum and by an increase in the number of mitochondria. These mitochondria are more variable in external form and often possess increased numbers of villiform cristae. Other features noted were a decrease in the amount of cytoplasmic lipid granules and an increase in cell size and surface irregularity. The significance of the morphological findings is discussed in relation to ovarian hormone production in animals sterilized by X-irradiation.

Incidence of mesophilic Clostridium spores in raw pork, beef, and chicken in processing plants in the United States and Canada. The anaerobic film pouch technique was used to quantitate and isolate clostridial spores in 2,358 samples of raw meat (1,078 of chicken, 624 of beef, 656 of pork). Of 19,727 putrefactive anaerobic (PA) sporeformers isolated, 1 was confirmed by mouse protection testing to be Clostridium botulinum type C. This isolate was obtained from a Western Canada chicken sample which contained 5.33 clostridia per gram. These data indicate a very low incidence of botulinal contamination in raw meats at the packing-plant level (0.042% of 2,358 samples) and an almost 20,000:1 ratio of nonbotulinal PA sporeformers to mesophilic C. botulinum spores. The mean level of PA contamination was 2.8 PA sporeformers per gram of meat; 77% of the samples contained three or less PA sporeformers per gram. Small but statistically significant differences in the incidence of clostridial spores were noted for season, geographical region, and type of meat.


Role of methionine in cephalosporin synthesis. Methionine has an almost unique stimulatory effect on biosynthesis of cephalosporins (by Cephalosporium acremonium). No other sulfur-containing compound tested, except dl-methionine-dl-sulfoxide, replaced methionine. dl-Methionine stimulated the synthesis of cephalosporins when added after the growth phase. The utilization of inorganic sulfate was repressed by methionine. Experiments with l-methionine-S(35) showed that essentially all the sulfur in the cephalosporins was derived from methionine. Sulfur-labeled compounds found in the soluble pool from cells grown with methionine-S(35) were methionine, homocysteine, taurine, cystathionine, cysteic acid, glutathionine, and cysteine. dl-Serine-3-C(14) was incorporated into the antibiotics, and its utilization was stimulated by methionine. l-Cysteine had a sparing effect on the incorporation of methionine-S(35) and serine-C(14) into the antibiotics. The data are consistent with the hypothesis that a cystathionine-mediated pathway is operative in the transfer of sulfur between methionine and cysteine.

Bacterial pollution indicators in the intestinal tract of freshwater fish. A study was made of the occurrence, distribution, and persistence of coliforms, fecal coliforms, and fecal streptococci in the intestinal tract of freshwater fish. A total of 132 fish representing 14 different species were used in various phases of these experiments. Examination of the intestinal contents of 78 fish from moderately polluted sections of the Little Miami River indicated that fecal coliform densities were lowest in bluegills (less than 20 per gram) and highest in catfish (1,090,000 per gram). Levels of fecal streptococci for these two species were 220 and 240,000 per gram, respectively. The occurrence of fecal coliforms in fish caught in this stream reflected the warm-blooded-animal-pollution level of the water. All fish used in this phase of the study were caught during July, August, and September when the water temperatures were between 13 and 18 C. The fate of fecal coliforms and Streptococcus faecalis in the fish intestine indicated that these organisms can probably survive and multiply when fish and water temperatures are 20 C or higher, but only when the organisms are retained in the gut for periods beyond 24 hr. Based on the biochemical reactions for 3,877 coliform strains isolated from 132 freshwater fish of 14 different species, 91.4% of all strains were composed of five IMViC types. In a similar study of the biochemical reactions of 850 streptococci isolated from the intestinal tract of 55 freshwater fish, the predominant strains included S. faecalis and various closely associated biotypes. No consistently recurring pattern for either coliforms or streptococci could be developed to identify species of fish investigated. The composition of the intestinal flora is, however, related in varying degree to the level of contamination of water and food in the environment.

Fatty acids of glycerophosphatides in developing chick embryonic brain and liver. Fatty acid compositions of glycerophosphatides of developing chick embryonic brain and liver were compared. In brain, ethanolamine and serine glycerophosphatides contained 30-40% polyunsaturated fatty acids, lecithin almost none (except for arachidonic). In the liver, these acids were equally distributed in the phospholipid fractions. The principal polyunsaturated fatty acids of the ethanolamine and serine glycerophosphatides in brain, liver, and yolk were 22:6, 20:4, and 18:2, respectively. During embryonic development of brain from the 8th day of incubation to hatching, the fatty acid composition of individual glycerophosphatide fractions remained constant. Because of the relative increase of ethanolamine glycerophosphatides and decrease of lecithin, total glycerophosphatides showed a decrease in 16:0 and an increase in 18:0. Substantial amounts of palmitaldehyde and stearaldehyde were present on the 8th day of incubation in the brain ethanolamine glycerophosphatide fraction. During the 3rd week of incubation, the liver showed a two-fold increase in the relative amount of 18:2 in all glycerophosphatide fractions. A decrease of 16:0 in the lecithin fraction and consequently in total glycerophosphatides was also observed during this period. No significant changes in glycerophosphatide fatty acids were observed in the yolk throughout incubation.


An indirect method to assay for mitotic centers in sand dollar (Dendraster excentricus) eggs. It is possible consistently to induce sea urchin and sand dollar eggs to cleave directly from one cell into four cells. This is done by exposing the fertilized eggs to benzimidazole for 20 to 30 min beginning about early metaphase. The mitotic apparatus regresses, the cells do not cleave, and shortly after they are returned to normal sea water an early-prophase-appearing nucleus is present in each cell. Each cell then organizes a tetrapolar tetrahedral mitotic apparatus de novo, instead of transforming a bipolar mitotic apparatus into a tetrapolar figure, and cleaves one-to-four. In another type of experiment, it appears that sand dollar eggs exposed to mercaptoethanol during the first period of mitotic center duplication have only half as many centers by first cleavage metaphase as the normal controls. This is consistent with an earlier report by Mazia et al (1960). Using this same experimental technique, it was demonstrated that benzimidazole, on the contrary, does not interfere with mitotic center duplication in sand dollar eggs. A labeling experiment demonstrated that benzimidazole does not interfere markedly with the normal pattern of incorporation of C(14)-thymidine into the DNA of sea urchin eggs. The data reported here suggest that judicious treatment of sand dollar eggs (and probably sea urchin eggs, too) with benzimidazole can induce the eggs to cleave into as many cells as there were mitotic centers sometime earlier, for example at early metaphase of the first cleavage division. This provides a very useful tool for studies on the process of mitotic center duplication.


Fine structure of the human ovum in the pronuclear stage. A penetrated ovum was recovered from the oviduct of a 33 year old surgical patient who had had sexual intercourse 26 hr before the operation. The ovum was in the pronuclear stage. The ooplasmic organelles were mainly represented by mitochondria, endoplasmic reticulum components, and Golgi elements. Small vesicles were found in the space between the two sheets of the pronuclear envelope. These vesicles appeared to be morphologically similar to the ER vesicles in the ooplasm and were considered to be involved in pronuclear development. Numerous annulate lamellae were seen in the ooplasm as well as in the pronuclei. Ooplasmic crystalloids were also observed. These were thought to represent cytoplasmic yolk. Remnants of the penetrating spermatozoon were found in close relation to one of the pronuclei. The fine structure of the first and second polar body is also described. The nuclear complement of the first polar body consisted of isolated chromosomes, whereas the second polar body contained a membrane-bounded nucleus. In consideration of the possibility that polar body fertilization may take place, these differences in nuclear organization could be of importance. Other recognizable differences between the two polar bodies were presence of dense cortical granules and microvilli in the first polar body, and absence of these structures in the second. These dissimilarities were considered to be related to the organization of the egg cytoplasm at the time of polar body separation.

Studies of spermiogenesis in a nematode, Nippostrongylus brasiliensis. The fine structure of the developing spermatids and the mature sperm of Nippostrongylus brasiliensis was investigated. Immature spermatids are found at one end of the tubelike testis, and the mature sperm at the other. The spermatid has a prominent nucleus, with the chromatin clumped at the margin. It also contains a pair of centrioles, located near the nucleus. The cytoplasm is filled with ribosomal clusters, but it lacks an organized Golgi area or endoplasmic reticulum. Besides the normal mitochondria, the spermatid has specialized mitochondrionlike inclusions with dense matrix, few broad cristae, and a crystalloid structure always facing the nucleus. As spermiogenesis proceeds, the nucleus elongates, comes to lie at one end, and later evaginates to form a separate head structure, leaving the mitochondria and other cytoplasmic organelles in a broad cytoplasmic region. The nuclear material becomes filamentous and spiral, and the centrioles come to lie at one end near the junction of the head and the cytoplasmic portion of the sperm. Microtubules are found in the cytoplasmic region extending from the tubelike nucleus. The specialized mitochondria are about eighteen in number, and are arranged in rows in staggered groups of three around the microtubules in the cytoplasmic region. The mature sperm is aflagellate and lacks an acrosome. No movement of the sperm was ever observed.

Influence of thyroxine and luteinizing hormone on some enzymes concerned with lopogenesis in adipose tissue, testis and adrenal gland. The activities of hexokinase, citrate-cleavage enzyme, ;malic enzyme' and NADP-linked isocitrate dehydrogenase have been measured in the adipose tissue, testes and adrenals of normal rats, hypophysectomized rats and hypophysectomized rats treated with either thyroxine or thyroxine plus luteinizing hormone. Hypophysectomy reduced the activity of all four enzymes in all three tissues. Thyroxine alone restored the activity of all four enzymes in adipose tissue towards normal but failed to do so in either testes or adrenals. Thyroxine and luteinizing hormone restored the citrate-cleavage enzyme activity of testes and increased the activity of hexokinase from the low value after hypophysectomy. Neither ;malic enzyme' nor isocitrate dehydrogenase was increased by thyroxine or thyroxine and luteinizing hormone in testes. The differential stimulation of enzyme activity by thyroxine in the different tissues suggests thyroxine as having a special significance in adipose-tissue lipogenesis.
