A cultural analysis of human behavioral breakdowns: An approach to the ontology and epistemology of psychiatric phenomena

This paper explores the usefulness of a concept of human behavioral breakdowns for studying psychiatric phenomena from a cross-cultural standpoint. The kinds of conceptualizations that are available in the English literature about human behavioral breakdowns across societies are reviewed. The way these breakdowns have been handled in the Western European Tradition of medicine is given special emphasis. Attention is focused on schizophrenia as one of the modern disease concepts of psychiatry that is a variant of human behavioral breakdowns. The essay then looks at schizophrenia using contemporary ideas about cultural relativism as these apply to the study of psychiatric phenomena in relation to society. Perspectives about the variable as versus the invariant in schizophrenia are reviewed.     

Mapping oligogenic resistance to powdery mildew in mungbean with RFLPs

We have used restriction fragment length polymorphisms (RFLPs) to map genes in mungbean (Vigna radiata) that confer partial resistance to the powdery mildew fungus, Erysiphe polygoni. DNA genotypes for 145 RFLP loci spanning 1570 centimorgans of the mungbean genome were assayed in a population of 58 F₂ plants. This population was derived from a cross between a moderately powdery mildew resistant (VC3980A) and a susceptible (TC1966) mungbean parent. F₃ lines derived from the F₂ plants were assayed in the field for powdery mildew response and the results were compared to the RFLP genotype data, thereby identifying loci associated with powdery mildew response. A total of three genomic regions were found to have an effect on powdery mildew response, together explaining 58% of the total variation. At 65 days after planting, two genomic regions were significantly associated with powdery mildew resistance. For both loci, the allele from VC3890A was associated with increased resistance. At 85 days, a third genomic region was also associated with powdery mildew response. For this locus, the allele from the susceptible parent (TC1966) was the one associated with higher levels of powdery mildew resistance. These results indicate that putative partial resistance loci for powdery mildew in mungbean can be identified with DNA markers, even in a population of modest size analyzed at a single location in a single year.     

The importance of a relative shortage of food in animal ecology

Summary It is proposed that for many if not most animals — both herbivore and carnivore, vertebrate and invertebrate — the single most important factor limiting their abundance is a relative shortage of nitrogenous food for the very young. Any component of the environment of a plant, by varying the amount of adequately nutritious plant tissue available to herbivores, may consequently affect the abundance of food through all subsequent trophic levels; in this regard weather may be important more often than is immediately obvious.The hypothesis proposes that animals live in a variably inadequate environment wherein many are born but few survive, and leads to a concept of populations being limited from below rather than controlled from above. And it may lead to a reappraisal of the role of predation, competition and social and territorial behaviour as factors likely to influence the numbers of animals in the environment, the response of pests to manipulation of populations of their food plants by Man, and the likely effectiveness of agents of biological control.     

Variation of glucose 6-phosphate dehydrogenase in the HeLa and Detroit 98 cell lines and their clonal derivatives

Contrary to other reports, we have found that the A type G6PD found in two permanent cell lines—HeLa (Gey), with its single cell clonal derivative HeLa S3, and Detroit 98, with its four clonal derivative lines—is not a single variant but rather at least three different isozymes. One is heat stable with normal specific activity and normal A type electrophoretic migration, another is heat labile with normal specific activity and normal A type electrophoretic migration, and the third is heat labile with reduced specific activity and slightly slow A type electrophoretic migration. We also found that in a mosaic cell population with respect to G6PD phenotype, the predominant G6PD phenotype varied randomly over a 5-month period, that the G6PD phenotype might be mutable in permanent cell lines, and that spontaneous human cell lines might not be HeLa cell contaminants as has been suggested.Aided by the National Institutes of Health General Research Support Grant # 5 S01 FR05507.     

Aminosäuren des Blutes bei Huntingtonscher Chorea

Free and bounded amino acids in blood serum and plasma of 13 persons with Huntingtons chorea (4 , 9 ) are studied using ion exchange chromatography. The gen of this hereditary disease causes no qualitative changes and no excessive quantitative anomalies of amino acids in blood serum—detectable with this method.—The concentration of arginine in the serum of all male and of five female patients was higher than normal. The valine/lysine ratio shows tendencies towards a catabolic process. The matter requires further investigations.

The “Bantu Clinic”: A Genealogy of the African Patient as Object and Effect of South African Clinical Medicine, 1930–1990

This paper is about power, medicine andthe identity of the African as a patient of westernmedicine. From a conventional perspective and asencoded in the current quest for wholeness thatcharacterises South African biomedical discourse, theAfrican patient – like any other patient – has alwaysexisted as an authentic and subjectified being, whosetrue attributes and experiences have been denied bythe mechanistic, reductionistic and ethnocentricpractices of clinical medicine. Against this liberalhumanist perspective on the body as ontologicallyindependent of power, this paper offers a Foucaultianreading of the African patient as – like any otherpatient – contingent upon the force relations immanentwithin and relayed through the clinical practices ofbiomedicine. A quintessential form of disciplinarymicro-power, these fabricate the most intimaterecesses of the human body as manageable objects ofmedical knowledge and social consciousness to makepossible the great control strategies of repression,segmentation and liberation that are the usual focusof conventional investigations into the place andfunction of medicine in society. Since the 1930s whenthe African body first emerged as a discrete object ofa secular clinical knowledge, these have repeatedlytransformed the attributes and identity of the Africanpatient, and the paper traces this archaeology ofSouth African clinical perception from then until the1990s to show how its quest for wholeness is not anend point of discovery or liberation, but merelyanother ephemeral crystallization of socio-medicalknowledge in a constantly changing force field ofdisciplinary power.     

Ecology and experimental biology

Summary 1. The definition of the word ecology is considered and the difficulties — both practical and theoretical — associated with a precise formulation outlined.2. Ecology as the study of systems consisting of components, or variables, each made up of a number of vectors is discussed.3. A comparison of the difficulties inherent in the definition with those — less apparent — in abiotic systems is made.4. The meaning of the word experimental is considered and its relation to a series of transformations on a biological system discussed.5. The meaning — in the restricted sense determined by the definitions given — of experimental ecology and the practical problems it poses are dealt with in some detail.6. The meaning of experimental biology and its relation to experimental ecology, as defined above, is discussed in relation to plant and animal systems.7. The future of ecology — experimental and otherwise is discussed.8. The increase in information will call for a greater integrative approach and the possible ways by which this can be achieved are outlined, particularly as they relate to the marine biological sciences.

Ökologie und experimentelle Biologie

Kurzfassung Der Begriff Ökologie wird erörtert und die praktischen sowie theoretischen Schwierigkeiten aufgezeigt, welche einer präzisen Definition im Wege stehen. Ökologie wird als ein Forschungsgebiet aufgefaßt, das sich mit dem Studium von Systemen beschäftigt, welche aus Komponenten oder Variablen bestehen, von denen jede wieder eine Anzahl von Vektoren enthält und Vergleiche mit abiotischen Systemen anstellt. Die Bedeutung des Wortes experimentell wird erörtert und dessen Beziehung zu einer Serie von Transformationen an einem biologischen System diskutiert. Eingehende Überlegungen werden dem auf Grund der gegebenen Definitionen eingeschränkten Begriffsinhalt experimentelle Ökologie und den praktischen Problemen gewidmet, welche dieses Forschungsgebiet uns aufgibt. Die Konotation des Terminus experimentelle Biologie wird behandelt und die Beziehung zwischen experimenteller Biologie und experimenteller Ökologie im Hinblick auf Pflanzen- und Tiersysteme diskutiert. Die Zukunft der Ökologie — experimentell und nichtexperimentell — bedarf besonderer Aufmerksamkeit. Das ständige Anwachsen der pro Zeiteinheit produzierten neuen Informationen macht eine stärkere Integration erforderlich; Vorschläge, wie dies erreicht werden könnte, werden vorgelegt, und zwar unter besonderer Berücksichtigung meeresbiologischer Aspekte.

     

Genetics of Ia-like alloantigens in chickens and linkage withB major histocompatibility complex

Two sets of backcross matings were performed to test for linkage between genes coding for the Ia-like antigens (Ia) and the B erythrocyte antigens (Ea-B) of the chicken. Evidence is presented which indicates that the la antigens are determined by a single codominant locus and that theEa-B and Ia loci are on the same chromosome. Failure to detect a single recombinant between theEa-B and Ia loci out of 208 progeny suggests close linkage of the two genes with a map distance of up to about 2 centimorgans. The Ia genes are thus included in theB major histocompatibility complex of the chicken.     

Conservation Implications of Behaviour and Growth of the Lake Sturgeon, Acipenser fulvescens, in Northern Ontario

We investigated the age, growth and population structure of lake sturgeon in the Groundhog and Mattagami rivers, northern Ontario, Canada. Age, estimated from counts of annuli in pectoral fin rays, ranged from 1 to 69 years (y) in the 327 fish examined. Growth, expressed as an increase in fork length and calculated from a von Bertalanffy growth equation, slowed from a peak of about 3.9cmyear^-1during the early juvenile period (<9y) and approached an asymptote beyond 90y (FL=141.549[–e^-0.043(t–4.901)]). A length–mass equation (log M=3.07 log FL–2.26) and conversion factors for fork and total length (FL=0.97 TL–1.154) from our study ranged from 14.5 to 142cm (fork length), 15.5 to 158cm (total length) and 20 to 19730g (live mass) for 1177 individuals. We found no evidence for spawning or recruitment to the population in our study area. Population age and length structure were strongly bimodal, and growth rate appears to have slowed over the past decade. We discuss the possible environmental correlations and conservation implications of this age (size) distribution.     

Über den Einfluß von Nahrung und Substratsalinität auf Verhalten,Fortpflanzung und Wasserhaushalt von Enchytraeus albidus Henle (Oligochaeta)

Zusammenfassung Enchytraeus albidus aus dem Anwurf mariner Algen an der Kieler Förde (Ostsee) erträgt als Nahrung die folgenden dort vorkommenden Pflanzen (Reihenfolge mit abnehmender Verträglichkeit): Fucus — Grünalgen —Seegras (Zostera) — Rotalgen (Delesseria). Diese Reihenfolge gilt für Nahrungsaufnahme, Fortpflanzungsrate und Überlebensdauer.Mit zunehmender Fäulnis des Nahrungssubstrates steigt die Zahl der Tiere, die aus ihm fliehen. Ihre Anzahl wird außerdem bestimmt durch den Salzgehalt des Substrates: Von 15–45 ist sie proportional der Substratsalinität. Bei 60 ist die Aktivität der Tiere bereits stark eingeschränkt.Bei Fucus-Nahrung ertragen auf Sand gehaltene Tiere eine Salinität von 60–70 länger als 4 Wochen, auf Filtrierpapier dagegen nur 50 für durchschnittlich 1 Woche. Die obere Fortpflanzungsgrenze liegt bei 40 Salzgehalt im Substrat. Bei 5 werden die meisten Kokons abgelegt. Die Sterblichkeit im Kokon ist bei 15 am geringsten. Auf den Substratsalinitäten 0–15 ist die Entwicklungsdauer im Kokon signifikant kürzer als auf Substraten von 30 und 40. Enchytraeus hat sich als Rückwanderer zum Meer mit einer sekundär erweiterten Poikilosmotie an den neuen Lebensraum angepaßt. Er kann eine Binnenkonzentration entsprechend etwa 72 längere Zeit ertragen. Auf niedrigen Salzgehalten besitzt er eine ausgeprägte Hypertonieregulation.

Summary Enchytraeus albidus was fed with Fucus, green algae, Zostera marina and Delesseria. Judging from absorption of food, rate of reproduction and duration of life, the animals preferred the plants in the sequence given above.As the putrefaction of a Fucus substrate advances, more and more enchytraeids leave it. A changing salinity of the substrate also influences the number of emigrating worms, increasing it from 15–45, but decreasing it towards 60. Fed with Fucus E. albidus tolerates a salinity of 60–70 on sand for more than 4 weeks, on filter paper only 50 for about one week.Reproduction is possible at salinities up to 40. Cocoon production is most frequent at 5. The mortality of young worms within the cocoons is lowest at 15. The incubation period is significantly shorter at salinities of 0–15 than at 30 and 40.As a terrestrial immigrant to the seashore Enchytraeus albidus secondarily enlarged its range of poikilosmosis, tolerating a concentration of 72 in its coelomic fluid for some time. At low salinities it maintains a remarkable degree of hyperosmosis.

     

Characterization of Melittin Effects in Synaptosomes

The effects of melittin at increasing concentrations on: [³H]GABA release from mouse brain synaptosomes; on the radioactivity released from [³H]arachidonic acid labeled synaptosomal membranes; on synaptosomes ultrastructure and on the leakage of the cytoplasmic marker, lactate-dehydrogenase (LDH) was investigated. Melittin 0.3, 1, 3, 7, and 10 M progressively increases [³H]GABA release, but the efficacy of melittin is decreased when the amount of tissue exposed to a constant concentration of the toxin increases. The release of [³H]GABA induced by melittin below 3 M is Ca²⁺ dependent, but not that induced by the higher concentrations. The Ca²⁺ dependent fraction of the [³H]GABA released by 0.3 M melittin is selectively inhibited by 10 M quinacrine and 1 M nordihydroguaiaretic acid (NDGA) and facilitated by 3 M indomethacin, whereas the Ca²⁺ independent fraction of the [³H]GABA released by melittin is not. In the presence of Ca²⁺, melittin 0.3, 1 and 10 M progressively increases [³H]arachidonic acid release over control release, but the effectiveness of melittin is also decreased as the amount of tissue increases. No apparent changes in synaptosomes ultrastructure are observed in 0.3 M treated synaptosomes, but a noticeable disorganization is produced in 10 M melittin-treated synaptosomes, independently on the presence of external Ca²⁺. LDH activity only increases over control activity in the supernatant solutions of 10 M melittin treated synaptosomes, also in a Ca²⁺ independent manner. Our interpretation of these results is that the Ca²⁺-dependent, pharmacologic sensitive component of melittin-induced release of [³H]GABA, unmasked when 0.3 M melittin was used, involves the activation of a Ca²⁺-dependent type of membrane PLA₂. The Ca²⁺-independent release of [³H]GABA is in contrast, highly probable to be due to the membrane perturbation produced by complex melittin/lipid interactions.     

Replication of chromosomal DNA in cultured abnormal human cells

Summary The replication of chromosomal DNA in a series of abnormal human cell cultures has been studied by means of DNA-fiber autoradiography. In lymphocytes with trisomy 21, in fibroblasts of 45,X; 47,XXX; 49,XXXXY; and 49,XXXXX chromosomal constitution, and in fibroblasts from a patient with xeroderma pigmentosum (De Sanctis-Cacchione syndrome), the rate of DNA replication does not differ from that in normal cells, varying in a single fork from 0.2 to 1.0 m/min with a mean of about 0.6 m/min. In fibroblasts with trisomy 7 the rate of DNA replication is greater, varying from 0.3 to 1.2 m/min with a mean of about 0.8 m/min. The sizes of replication units in all cells examined are from 80 to 500 m with a mean of about 200–300 m.     

Effects of losartan on the collagen degradative enzymes in hypertrophic and congestive types of cardiomyopathic hamsters

The present study was undertaken to determine the effects of AT1 receptor blockade which occurred in response to losartan, on the extracellular matrix (ECM) degradation process in the Bio 14.6 (n = 12) and Bio 53.58 (n = 12) strains which are referred as models of hypertrophic and dilated cardiomyopathy, respectively. The administration of losartan (30 mg/kg/day) in hamsters from 10–20 weeks of age reduced the accumulation of the left ventricular collagen matrix in both of the Bio 14.6 and the Bio 53.58 strains. According to the RTPCR, the levels of mRNA for matrix metalloproteinase (MMP) and the tissue inhibitor of MMP (TIMP) were examined. MMP1, 2, 3, and 9 were more enhanced in both myopathic strains than in the control F1 strains. With losartan, the levels of MMP1, 2, 9, TIMP1 and 2 decreased in the both strains but those for MMP3 did not in Bio 14.6 strains. TIMP3 and 4 mRNA levels did not change in any of the experimental hamsters, whether treated or untreated with losartan. The Western blots also showed similar observations in the both strains as seen in mRNA expressions although MMP2 in the Bio 53.58 strains did not differ between treated and untreated with losartan. Although losartan has an inhibitory effect on collagen accumulation in the development of cardiomyopathy, MMPs (1, 2, 9) and TIMPs (1, 2) seem to be susceptible to responding to losartan in Bio cardiomyopathic hamsters.     

The Third Therapeutic Revolution: Behavioral Medicine

Behavioral medicine—and one of its progenitors, biofeedback—are expanding as the Third Therapeutic Revolution, supplementing surgery and pharmacology in treating human illnesses. Parallel development of nonscience-based therapies is a part of the same revolution. Labeling their positive results as placebo effects hides a greater truth: faith and trust play an enormous role in therapy. The successes of both behavioral medicine and unorthodox complementary medicine are the result of thedebonafide effect(my Latin for from good faith). Readers are urged to adopt this better definition of the unexplicable and substantial good results of both the placebos in research and the ministration of unorthodox treatments.     

Frostbite and the significance of a temperature-sensation scale in field and laboratory conditions

The literature indicates that rapid thawing in water between 42 and 45C provides the best prognosis for frostbitten limbs.A temperature:sensation scale for the normal hand was derived and tested in laboratory and field conditions. The scale permitted the preparation of water suitable for frostbite treatment by the majority of subjects without access to a thermometer. The maximum observed inaccuracy was 1.2C outside the preferred range but was well withing the safe range for treatment.

Zusammenfassung Die beste Prognose zur Behandlung von Erfrierungen bietet nach den Erfahrungen in der Literatur das schnelle Auftauen von erfrorenen Gliedern bei Wassertemperaturen von 42–45C. Für die gesunde Hand wurde eine Temperatur-Wahrnehmungsskala aufgestellt und unter verschiedenen Bedingungen im Laboratorium und im Freien geprüft. Ohne Zugang zu einem Thermometer gestattete die Skala in der Mehrzahl der FÄlle die ErwÄrmung von Wasser auf Temperaturen, die für die Behandlung von Erfrierungen geeignet sind. Die grösste Ungenauigkeit zwischen SchÄtzwert und Thermometerwert war 1.2C ausserhalb des gewünschten aber noch innerhalb des für die Behandlung zulÄssigen Bereiches.

Résumé D'après les indications de plusieurs auteurs, le meilleur traitement de membres gelés consiste à les dégeler dans de l'eau à une temperature entre 42 et 45C. Une échelle température-sensation pour la main normale a été mise au point et vérifiée au laboratoire ainsi qu'en plain air.Cette méthode a permis la préparation d'eau en vue d'un traitement de gelures sans faire usage d'un thermomètre dans la plupart des cas. L'erreur maximum observée était de 1,2 C sans que les limites de l'intervalle propice à un traitement ne soient jamais dépassées.

     

Development and parasitism in the genus Hemileia (uredinales)

Seventeen species ofHemileia were studied with emphasis on these characters: extent of colonization, specialization of parasitic mycelium, haustorial development, pathologic histology, soral morphology and sporulation capacity. An attempt was made to trace the varying degree of development and parasitism in this rust genus comprising of just over 40 reported species. It was noted that theGopalkrishnan's Subepidermal type more advanced than his Superstomal — B type.Fourth part of my thesis submitted to the University of Poona, India, accepted in 1968 for Ph.D. Not published.     

Weather and the incidence of urinary stone colics in the Province of Florence

The present study analyses the case histories of urinary stone colics recorded at the hospital Val di Sieve (Florence) during the period 1962–1971 by comparing the weather conditions of the 353 days during which the cases occurred, with the weather conditions of a sample of normal reference days.From the analysis it seems to emerge that a hot and — at the same time — dry weather, as well as wide changes in air pressure, may favour in predisposed individuals the onset of urinary stone colics.
