Symposium on allergic lung disease. I. The clinical picture of asthma. Life-threatening asthma may be judged to be present in patients who, in the presence of a low FEV(1) are too dyspneic to speak, have altered consciousness or unequivocal cyanosis. Other physical signs which indicate airway obstruction of grave severity are pulsus paradoxus, gross thoracic overinflation and electrocardiographic evidence of pulmonary hypertension. A rise in the arterial CO(2) tension, the presence of pneumothorax or pneumomediastinum, and an FEV(1) less than 1 litre and vital capacity less than 0.5 litre, failing to increase immediately after inhalation of a bronchodilator, are also features which demand urgent and intensive therapy.Corticosteroids in large doses should be administered whenever a life-threatening situation is recognized. Systemic steroids should be stopped only when the danger phase, as indicated by the criteria given above, has been reversed. At all stages of therapy regular inhalations of a sympathomimetic bronchodilator should be maintained. Oral steroid therapy should be continued until maximum ventilatory function has been attained; only then should dose reduction be attempted.

Effect of bovine parathyroid hormone 1-34 fragment on renal production and excretion of adenosine 3', 5' monophosphate in man. Biologically active bovine parathyroid hormone (b PTH) 1-34 fragment infused over one hour in normal subjects produced an immediate and sharp increase in the excreted fractions of filtered bicarbonate, sodium and potassium, followed by the return to pre-infusion levels as soon as the administration of b PTH was stopped. There was a gradual but steady increase in the excreted fraction of filtered phosphate but a decrease in the excreted fraction of filtered calcium and magnesium. The excreted fractions of these ions were still abnormal 150 minutes after the completion of PTH infusion. The urinary excretion of 3'5'-cyclic AMP increased immediately about one hundred-fold but returned rapidly to pre-infusion levels. Urinary clearance of cyclic AMP approximated glomerular filtration rate in control periods and was twenty to thirty times greater during b PTH infusion. In subjects overloaded with bicarbonate, b PTH brought about a decrease in bicarbonate T(m) and the same effects on the urinary excretion of other electrolytes. 3'5'-cyclic AMP excretion was clearly higher in control periods and reached higher levels during b PTH infusion when compared to subjects without an alkaline load. 3'5'-cyclic AMP excretion and fractional clearance were also clearly higher in subjects not given b PTH when control periods were compared to periods with bicarbonate infusion or after acetazolamide administration. During distal blockade obtained by simultaneous administration of chlorothiazide and ethacrynic acid, there was a delay in the rise of 3'5'-cyclic AMP excretion after b PTH administration. It can be concluded from these studies that the pattern of excretion of 3'5'-cyclic AMP is similar to that of bicarbonate, sodium and potassium. The increase of 3'5'-cyclic AMP excretion when urinary pH is above 7 suggests a diffusion trapping mechanism for the secretion into the lumen of this nucleotide. Distal diuretics used in distal blockade did not inhibit 3'5'-cyclic AMP production but delayed its secretion into urine.

Skeletal muscle lipids. II. Changes in phospholipid composition in man from fetal to middle age. Phospholipid compositions were determined in samples of gastrocnemius muscles of individuals from fetal stage to the age of 55 yr. The lipids were separated by thin-layer chromatography. In order to enable characterization of the individual phospholipids, a lipid extract was prepared from pooled samples of gastrocnemius muscles from adult males and separated by ion-exchange chromatography on TEAE-cellulose. The individual phosphoglycerides were purified by thin-layer chromatography and then characterized according to their content of fatty acids, aldehydes, phosphorus, and the identity of the bases. The relative amounts of the major phospholipids, choline and ethanolamine phosphoglycerides, changed little with age, and in adult males they constituted 47% and 24%, respectively. Cardiolipin increased from 3% in the fetal stage to 9% by the end of the first year of life. Sphingomyelin and serine phosphoglyceride decreased with increasing age, while inositol phosphoglyceride increased. In adult males, cardiolipin constituted 10% of total lipid phosphorus, inositol phosphoglyceride constituted 9%, serine phosphoglyceride 3%, and sphingomyelin 7%.


Skeletal muscle lipids. 3. Changes in fatty acid composition of individual phosphoglycerides in man from fetal to middle age. The fatty acids in cardiolipin, choline phosphoglyceride, ethanolamine phosphoglyceride, inositol phosphoglyceride, and serine phosphoglyceride in the human gastrocnemius muscle were studied for changes between early fetal age to middle age. In cardiolipin, choline phosphoglyceride, and ethanolamine phosphoglyceride, the relative total amount of the linoleic acid series increased considerably during the prenatal period and reached maximum values during the first year of life. In inositol phosphoglyceride and serine phosphoglyceride, only slight changes in the sum of fatty acids of the linoleic acid series were found. An increase in the concentration of fatty acids of the linolenic acid series was found in ethanolamine phosphoglyceride and serine phosphoglyceride, while only minor amounts of these fatty acids were present in choline phosphoglyceride and inositol phosphoglyceride and not at all in cardiolipin. During the period studied, the amount of plasmalogen in ethanolamine phosphoglyceride decreased slightly during the first year of life and then remained at 40%. The amount of plasmalogen increased in choline phosphoglyceride from 8% at the middle of the gestational period to 15% 1 yr after birth. The individual phospholipids were found to have characteristic fatty acid patterns.


Synthesis and turnover of cerebroside sulfate of myelin in adult and developing rat brain. The turnover of cerebroside sulfate (sulfatide) was followed in both microsomal and myelin fractions of developing and adult rat brains after an intracerebral injection of Na(2)(35)SO(4). In the adult rats, the specific radioactivity of sulfatide of the microsomal fraction reached a maximum 12 hr after the injection, and after 3 days it was reduced to less than 30% of the maximum. In contrast, the specific radioactivity of the myelin sulfatide did not reach a peak until 3 days after the injection and remained essentially at the same level for as long as 6 months. In the case of 17-day-old rats, the specific radioactivity of myelin sulfatide reached a maximum level around 12 hr after the injection and then appeared to decline. The decline was most marked 2-6 days after the injection, suggesting an apparently rapid turnover of myelin sulfatide. When a correction was made for deposition of newly formed sulfatide, the results indicated that the turnover of myelin in the developing animals was also relatively slow. In vitro experiments with purified myelin and 3'-phosphoadenosine-5'-[(35)S]phosphosulfate showed that myelin does not catalyze the galactocerebroside sulfotransferase reaction. This enzyme was found mainly in the microsomal fraction. In vivo studies suggested that a transfer of sulfatide molecules from the endoplasmic reticulum to myelin might occur. In order to obtain direct evidence for such a transfer, rat brain slices after pulse labeling with Na(2)(35)SO(4) were washed free of the isotope and reincubated with nonlabeled Na(2)SO(4). The specific radioactivity of the microsomal sulfatide declined, with a concomitant rise in the specific radioactivity of the myelin sulfatide. These observations are therefore consistent with the postulate that myelin sulfatide is probably synthesized in the endoplasmic reticulum.


Measurement of sulfated and nonsulfated bile acids in human serum and urine. Amberlite XAD-2 was used to extract bile acids from urine or diluted serum of patients with hepatobiliary diseases. Columns containing Sephadex LH-20 were then used to separate the sulfated and nonsulfated bile acids. Thin-layer chromatography of the sulfated bile acid fraction obtained from urine revealed several spots with R(F) values different from those of the taurine or glycine conjugates. According to thin-layer chromatographic mobilities, gas-liquid chromatographic analyses, infrared spectra, and elementary analysis of the sulfated material, one of these sulfated bile acids was identified as glycochenodeoxycholic acid monosulfate, and the others were presumed to be taurochenodeoxycholic acid sulfate and glycocholic acid sulfate. A large amount of bile acid sulfate was found in urine of patients with hepatobiliary diseases. They accounted for 35.5-93.3% of total urinary bile acids and consisted of both di- and trihydroxycholanoic acids, with chenodeoxycholic acid as the major acid. Sulfated bile acids were also found in serum, and accounted for 1.8-21.2% of the total bile acids. Only dihydroxycholanoic acids (mainly chenodeoxycholic) were identified.


Isolation and identification of cerebrosides from the marine sponge Chondrilla nucula. A cerebroside mixture has been isolated from the marine sponge Chondrilla nucula. Acid-catalyzed methanolysis of this cerebroside mixture afforded methyl glucosides, three long-chain bases, and a mixture of alpha-hydroxy fatty acid methyl esters. The bases were identified as saturated C(17), C(18), and C(19) trihydroxy bases (1,3,4-trihydroxy-2-aminoalkanes) by gas-liquid chromatographic-mass spectrometric analysis of their corresponding trimethylsilyl derivatives. The methyl ester fraction consisted of a mixture of homologous C(16) to C(26) saturated straight-chain alpha-hydroxy esters plus a trace of saturated C(25) iso alpha-hydroxy ester.


Determination of hepatic cholesterol 7alpha-hydroxylase activity in man. Methods were developed to determine the activity of the microsomal enzyme cholesterol 7alpha-hydroxylase in human liver. The enzyme assay could be performed with as little as 20 mg of fresh liver tissue, thus making the procedure applicable to specimens obtained by percutaneous liver biopsy. Optimal assay conditions were determined and the identity and radioactive purity of the reaction product, cholest-5-ene-3beta,7alpha-diol (7alpha-hydroxycholesterol) were established. Specific enzyme activity was measured in a number of patients with disorders of lipid metabolism.


Monoglyceride modification of jejunal absorption of fatty acid in the rat. The effect of increasing the intracellular pool of monoolein upon the subsequent uptake and esterification of oleic acid was investigated using in vitro rat jejunal slice techniques. The mucosal pool of monoglyceride was expanded by preincubation of jejunal slices in a monoglyceride-containing bile salt medium at a temperature close to 1 degrees C, which inhibited esterification. Subsequent incubation in micellar [(14)C]oleic acid was performed either at 37 degrees C or in the cold. Monoglyceride preincubation increased [(14)C]oleic acid uptake by about 60% without increasing incorporation of fatty acid into triglyceride. This was not due to inhibition of esterifying capacity nor to changes in oleic acid binding to a mucosal fatty acid-binding protein. It is suggested that under these experimental conditions monoglyceride may modify intracellular pools of fatty acid. However, when monoglyceride and fatty acid were preincubated together, mucosal esterification rates during subsequent incubation at 37 degrees C more than doubled. Implications of these data for present theories of rate-limiting steps in lipid absorption are discussed.


A simple and inexpensive membrane "lung" for small organ perfusion. A disposable coil of thin-walled Silastic tubing, permeable to oxygen and carbon dioxide, functioned as a "lung" for perfusion of isolated rat liver. This "lung," which can be easily assembled from laboratory supplies, has a number of advantages over devices that utilize large air-liquid interfaces for gas exchange. Rates of hepatic lipoprotein triglyceride secretion, comparable to those obtained with more complex oxygenation systems, are achieved with this simple device.

Unwanted pregnancy and mental health.

Unwanted pregnancy and mental health. This article deals with a study carried out in Glasgow of 132 referrals for psychiatric opinion on termination of pregnancy with a follow-up 9 months later.  A questionnaire was completed by the consultant at the time of examination and a follow-up letter was sent to the patient's family doctor 9 months later.  Of the 132 women, 84 were given an abortion and 48 were refused.  Of the 84 recommended for abortion, 53 were married, 25 single, and 6 widowed or divorced.  19 were childless and 65 had 1 or more children.  25% were Roman Catholic.  Continuing psychiatric symptoms were noted in 8, but only in 4 did they seem to result from the abortion.  Severe social problems were recorded in 9 but they had existed in 7 before and probably would have worsened had the abortion not been carried out.  Only 14 went to their general practitioner for contraceptive advice.  Of the 48 patients refused an abortion, only 25 continued the pregnancy to term.  15 had abortions privately.  Definite psychiatric sequelae occurred in 3 cases, none needing psychiatric referral.  Social problems arose in 4 cases.  There was apparently no evidence of psychiatric complications following abortion, but in the group refused abortion, there were cases of depression and social distress.

Human population and the global environment. A stable ecosystem resists large, rapid changes in the sizes of its constituent populations which upset the orderly flow of energy and nutrients.  An early example of such alteration was the conversion to desert of the rich Tigris and Euphrates valleys through erosion and salt accumulation resulting from faulty irrigation practices that caused the downfall of the great Mesopotamian civilization.  Overgrazing and poor cultivation practices have contributed over the millennia to the expansion of the Sahara Desert.  Attempts to cultivate too intensively the fragile soil of tropical rainforest areas are suspected of being in part responsible for the collapse of the Mayan civilization.  The 19th century Irish potato famine because of heavy reliance of the Irish population on a single, highly productive crop led to 1.5 million deaths when the potato monoculture, a simple agricultural ecosystem, fell victim to a fungus.  Modern agriculture's desire to maximize yields per acre are worrisome ecologically (increases in the use of pesticides and inorganic fertilizers).  The liabilities include that as larger land areas are farmed the tracts available for reservoirs of species diversity and for natural ecosystems become smaller.  Pressure to expand agriculture to steep hillsides unsuitable for cultivation has led to serious erosion in Indonesia, and increasing slash-and-burn practices are destroying tropical forests in the Philippines.  The enormous expansion of wheat or rice monoculture has increased the probability of epidemic crop failure from insects or disease.  37% of the world's population is under 15 years of age which means that population will grow for 50-70 years more before leveling off.  Despite a declining growth rate population would still increase 30% or more during the transition to stability.  Zero global population growth is required for a prosperous and environmentally sustainable civilization.

Recent developments in the analysis of toxic elements. One may conclude that it is impractical to confine oneself to any one analytical method since ever more sensitive instrumentation continues to be produced. However, in certain methods such as anodic stripping voltammetry and flameless atomic absorption it may be background contamination from reagent impurities and surroundings rather than instrument sensitivity which controls the limits of element detection. The problem of contamination from dust or glassware is greatly magnified when the sample size becomes ever smaller. Air entering laboratories near highways may contain trace quantities of lead, cadmium, barium, antimony, and other elements from engine exhaust. Even plastic materials contacting the sample may be suspect as a source of contamination since specific metals may be used as catalysts in the synthesis of the plastic and traces may be retained in it. Certain elements may even be deliberately added to plastics during manufacture for identification purposes. Nondestructive methods such as neutron activation and x-ray techniques thus offer great advantages not only in time but in the elimination of impurities introduced during sample ashing. Future improvements in attainable limits of detection may arise largely from progress in the ultrapurification of reagents and "clean-room" techniques. Finally, the competence of the analyst is also vitally important in the skillful operation of modern complex analytical instrumentation and in the experienced evaluation of data.

Lateral phase separation of lipids in plasma membranes: effect of temperature on the mobility of membrane antigens. Cooling populations of newly formed mouse human heterokaryons has effects on the intermixing of mouse and human surface antigens which indicate the occurrence of phase separations in membrane lipids. Antigen mixing, previously shown to be due to diffusion in the plane of the membrane, is retarded when cells are cooled from 37 degrees to 21 degrees C, but is then speeded by further cooling to 15 degrees C. This result is in accord with observations on phase separations of lipids in artificial and bacterial membranes.


Taurine concentrations in congestive heart failure. The concentration of taurine in the left ventricular muscle of hearts of patients who died of chronic congestive heart failure was twice that of patients who died of other causes and had no cardiac pathology. There was no corresponding difference in taurine concentrations in aortic tissue between the two groups. Stress-induced hypertension in rats also led to an increase in taurine concentration in the heart, whereas that in skeletal muscle and brain showed no significant alteration when compared to unstressed animals. Spontaneously hypertensive rats, of the Wistar-derived Okamato strain, showed a similar elevation in cardiac taurine compared to age-matched control Wistar rats.

Growth hormone responses to melatonin in man. Oral administration of 1 gram of melatonin caused rapid and significant elevations of serum human growth hormone in eight out of nine normal male subjects. The mean (+/- standard error of the mean) of the peak response by growth hormone was 22.9 +/- 4.6 microunits per milliliter. The increased secretion of growth hormone may be due to interaction of melatonin with hypothalamic serotoninergic receptors.


Pierce's disease of grapevines: evidence for a bacterial etiology. A Gram-positive, rod-shaped bacterium was isolated and grown in pure culture on artificial mediums from the leafhopper Draeculacephala minerva Ball which had fed on plants infected with Pierce's disease. The bacterial culture was injected into uncontaminated leafhoppers which were than allowed to feed on healthy grapevines. After exposure to these leafhoppers, typical symptoms of Pierce's disease developed; however, no symptoms developed on plants exposed to leafhoppers injected with sterile culture medium. The same organism was reisolated from the experimentally inoculated plants. Electron microscopic examination of these infected plants revealed bacterial cells localized in the xylem tissues. No such cells were seen in healthy or control plants.


Geckos: adaptive significance and energetics of tail autotomy. Coleonyx variegatus is adapted to readily sacrifice its tail to predators. This adaptation is associated with characteristic tail behavior and rapid tail regeneration. There is no facultative metabolic increase associated with tail regeneration, and energy normally allocated to body growth and maintenance is diverted to tail regeneration. This supports the contention that tail behavior, autotomy, and rapid regeneration evolved as mechanisms promoting survival in terms of predator escape.

Genetic mapping of Ir locus in man: linkage to second locus of HL-A. Fifty-seven members of a family that spanned three generations were studied for antigen E and ragweed skin sensitivity and HL-A antigens. There was significant association between the haplotype HL-A 2-12 and antigen E skin hypersensitivity (F = .22 to .26) in this family. The map order is first locus of HL-A, second locus of HL-A, and IrE. These determinants are considered to be part of the linkage group HL-1.


Unusual Yersinia enterocolitica isolates not associated with mesenteric lymphadenitis. Thirteen Yersinia enterocolitica were recovered from a variety of clinical sources. Of these, only one was associated with mesenteric lymphadenitis and belonged to serotype 8. The 12 remaining strains were isolated from nonmesenteric sources and belonged to serotype 17. All strains exhibited the main characteristics of Y. enterocolitica which differentiated them from other Enterobacteriaceae, i.e., motility at 22 C but not at 37 C, positive urease and ornithine decarboxylase activities, and negative phenylalanine deaminase. These 12 strains differed, however, from other Y. enterocolitica previously described in the United States in that they fermented rhamnose and raffinose at 22 C, and failed to grow on Salmonella-Shigella and Hektoen-Enteric agars.


Plate hemolysin test for the rapid screening of toxoplasma antibodies. A plate hemolysin test was developed to screen serum specimens for the presence of toxoplasma antibodies. When we tested 130 sera by both this test and the standard toxoplasma dye test, we found the plate hemolysin test to be a rapid, sensitive, and economical method for detecting toxoplasma antibodies. In all but one instance it paralleled the dye test. A comparison of the results of testing six sera by the hemolysin, hemagglutination, and dye-test techniques suggested that the hemolytic antibodies were more closely related to hemagglutinating antibodies than to dye-test antibodies. We could not store sheep erythrocytes sensitized with toxoplasma lysate for more than 3 days without altering the sensitivity of the test. Concanavalin A proved to be an effective coupling agent for binding toxoplasma antigens to red-cell membranes, a quality attributed to its affinity for specific polysaccharide-combining sites.


Production and some properties of a new type of acid carboxypeptidase of Penicillium molds. Among some 38 strains of the genus Penicillium we investigated seven wild-type strains (P. daleae IFO-6087, P. frequentans AHU-8328, P. funiculosum IAM-7013, P. janthinellum IFO-8070, IAM-7026, P. lividum IAM-7200, and P. oxalicum AHU-8336) that were found to be excellent strains for a new type of acid carboxypeptidase production in a surface koji culture at 25 C. The production of acid carboxypeptidase was determined in various culture conditions in a koji culture. The maximum yields of acid carboxypeptidase were obtained by P. janthinellum IFO-8070. Partial purification and isolation of the acid carboxypeptidase from strains of Penicillium were performed with gel filtration on Bio-Gel P-100. Characterization studies indicate that the acid carboxypeptidases from P. daleae IFO-6087, P. funiculosum IAM-7013, P. janthinellum IFO-8070, and P. oxalicum AHU-8336 have some properties similar to those of the enzyme of Aspergillus saitoi with regard to the hydrolysis of several peptides at acidic pH range but have other slightly different properties with regard to stability, pH optima, inhibitors, and molecular weights.

Ultrastructure of a thermotolerant basidiomycete possibly suitable for production of food protein. The imperfect cellulolytic fungus Sporotrichum pulverulentum, which is commonly found growing in wood-chip piles, was grown in submerged culture on wheat shorts and other cereal flours. These substrates were broken down in 1 to 4 days at 30 to 40 C, and the mycelial mass was easily harvested by filtration. Scanning electron micrographs of hyphae in mycelial pellets are presented, and thin sections of conidia and hyphae were studied in a transmission electron microscope. Dolipores in septa of hyphae were observed, and cell walls are shown to be lamellar, which is characteristic of the Basidiomycetes. Actively growing hyphae are full of cytoplasm with numerous mitochondria, whereas old mycelial pellets contain highly vacuolated and almost empty cells.

Likelihood analysis of recombinational disequilibrium in multiple-locus gametic frequencies. Likelihood methods are developed for the estimation and testing of multiple-locus gametic disequilibria, using log-linear models of parametric effects. The estimates of disquilibrium are related to Kimura's Z-measure, and may be extended to multiple alleles and multiple loci. Likelihood ratio test criteria are constructed, which are asymptotically distributed as chi(2). The analysis is partitioned into various components corresponding to two-locus, residual three-locus, and higher order disequilibria. A four-locus example from Hordeum vulgare L. is utilized to illustrate the analysis. Most of the multiple-locus disequilibrium is accounted for by two-locus effects, and closely linked loci show considerably more disequilibrium than unlinked loci. It is shown that all possible pairwise comparisons are not statistically independent.


Selection for blood pressure levels in mice. Response to two-way selection for systolic blood pressure was immediate and continuous for about eight generations. In the twelfth generation, the High males differed from the Low males by 38 mmHG; the females differed by 39 mmHg. There was little overlap between the two lines and they were statistically significant from each other and from the Random control line. There appeared to be no more additive genetic variance in the eleventh and twelfth generations. Causes for the cessation of response are explored. This is probably due to a combination of natural selection acting to reduce litter sizes in the Low line, a higher incidence of sudden deaths in the High line, and loss of favorable alleles as both selection lines went through a population bottleneck in the ninth generation.-In the eleventh generation, the selected lines were used to produce F(1), F(2), and backcross generations. A genetic analysis yielded significant additive and dominance components in the inheritance of systolic blood pressure.


Multivariate analysis of genetic variation. Multiple factor analysis was used to interpret geographical variation of gene frequencies. Allelic frequencies at three loci (two esterase loci, Esr and Esh, and a malic dehydrogenase locus) from ants (Pogonomyrmex barbatus) collected throughout Texas and reported by Johnsonet al. (1969) were reexamined for patterns of correlation with five environmental measurements: mean January temperature, mean July temperature, mean annual precipitation, elevation, and annual growing season. These measurements and the associated gene frequencies at each sampling location were subjected to factor analysis. Variables highly correlated with the same factor were hypothesized to be causally related. Both orthogonal and oblique rotations of the factor solution provided four factors with essentially the same interpretation. Variation at the Esh locus was associated with a continuum from cold-wet to hot-dry. Variation at the Mdh locus and some of that at the Esr locus was related to the severity of winter months. Other allelic frequencies at the Esr locus had high correlations with a third factor which seemed to be independent of the environmental measurements. None of the allelic frequencies had high correlations with the fourth factor which was interpretable as an altitudinal gradient.


Nautural selection for within-generation variance in offspring number. In this paper it is shown that natural selection can act on the within-generation variance in offspring number. The fitness of a genotype will increase as its variance in offspring number decreases. The intensity of selection on the variance component is inversely proportional to population size, although the fixation probability of a gene which differs from its allele only in the variance in its offspring number is independent of population size. The concept of effective population size is shown to be of limited use when there is genetic variation in the variance in offspring number.


Isoallele frequencies in very large populations. The frequencies of electrophoretically distinguishable allelic forms of enzymes may be very different from the corresponding frequencies of structurally distinct forms, because many sequence variants may have identical electrophoretic charge. In large populations such frequencies will be determined largely by the number of amino acid sites that are free to vary. The number of distinguishable electrophoretic variants will remain fairly small. Beyond some limiting size, no further effect of population size on allele frequencies is expected, so isolated large populations will have closely similar allele frequencies if polymorphism is due largely to mutation and drift. The most common electrophoretic alleles are expected to be flanked by the next most common, with the rarer alleles increasingly distal. Neither strong selection nor mutation/drift interpretations of enzyme polymorphism are yet disproven, nor is any point between these extremes.


Simulation studies on electrophoretically detectable genetic variability in a finite population. Using a new model of isoalleles, extensive Monte Carlo experiments were performed to examine the pattern of allelic distribution in a finite population. In this model it was assumed that the set of allelic states is represented by discrete points on a one-dimensional lattice and that change of state by mutation occurs in such a way that an allele moves either one step in the positive direction or one step in the negative direction on the lattice. Such a model was considered to be appropriate for estimating theoretically the number of electrophoretically detectable alleles within a population. The evenness of allelic distribution was measured by the ratio of the effective to the actual number of alleles (n(e)/n(a)). The results of the Monte Carlo experiments have shown that this ratio is generally larger under the new model of isoalleles than under the conventional Kimura-Crow model of neutral isoalleles. In other words, the distribution of allelic frequencies within a population is expected to be more uniform in the new model. By comparing the Monte Carlo results with actual observations, it was concluded that the observed deviation from what is predicted under the new model with selective neutrality is not in the direction of conforming to the overdominance hypothesis but is, in fact, in the opposite direction.
