Homosexual men and women who served their country.

The present work examines the effectiveness of United States military policies in excluding homosexual men and women from the armed forces by comparing percentages of homosexuals who have served in the armed forces with matched samples of heterosexuals. Interview data on 1,456 respondents from 1969 and 1970 are reported. The data show that homosexual and heterosexual men seem equally likely to have served in the military, while lesbians were more likely than heterosexual women to have served. The data also indicate that the policies of excluding homosexuals from the services are ineffective. The explanation for this may be that many homosexuals may not be aware of their homosexuality at time of entry into the service, and, hence, cannot readily be identified either by themselves or others. It is also suggested that certain draft criteria have in fact increased the percentages of homosexuals serving in the military.

Sexual orientation as destiny.

The article argues that social constructionists are referring to labels applied to sexual orientation while essentialists are discussing sexual orientation itself. Although a review of the literature shows that various labels are applied to sexual orientation, these labels do not markedly affect its reality. Sexual orientation, defined as erotic attraction rather than sexual behavior, is established at an early age and largely immutable in adulthood.

Defeminization and adult psychological well-being among male homosexuals.

Whitam's hypothesis that a majority of gay men exhibit a cross-gender role preference during childhood but that most defeminize by adulthood was tested and supported by data on 1556 gay men. Gay and heterosexual males were found to differ strongly in cross-gender characteristics during childhood but considerably less so during adulthood. By categorizing gay respondents simultaneously by both childhood and adult cross-gendering, sizable differences were found in measures of psychological well-being. No or minimal differences were found between homosexual and heterosexual males on these measures. It was suggested that these two groups may differ not at all or minimally on purely psychological measures but that major differences may be found in cultural variables and particularly in gender culture.

Decision making and age differences among gay male couples.

There appear to have been three major historical forms for male homosexual relationships: the Latin American model patterned after gender-roles, the Greek model involving a mature adult male and an adolescent male, and the modern form between males of approximately equal ages. The patterning of attractions among men of various ages is explored in a sample of 1,556 Chicago area homosexual males. The dominant trend found was for attraction towards persons of similar ages. Age differences between partners in liaisons were found to be associated with differences in decision making.

Choroidal neurilemmoma--an unusual clinical misdiagnosis.

A case of choroidal neurilemmoma is reported. After a period of clinical observation which included serial fundus photography and fluorescein angiography, during which time active growth was seen, the tumour was thought to be a malignant melanoma, and enucleation was considered the treatment of choice. Subsequent histological study revealed a neurilemmoma. Important points relating to the clinical diagnosis of lesions presenting in this way are discussed.

Age and sexual culture among homosexually oriented males.

It is here argued that the thesis has been overgeneralized that the culture of homosexually oriented males is heavily youth oriented. It is suggested that any "youth orientedness" is due to their largely single "marital status" rather than to sexual orientation. Utilizing data from 243 males from the Detroit area, several qualifications to the thesis of youth orientedness are indicated. It was found that a majority of males aged 18-24 prefer a male partner who is older, a majority of those aged 25-34 years prefer a same-age person, and 50% of theose over 35 prefer a younger partner. These relationships were found to be especially strong among those segments of the sample who attend gay bars infrequently or who are of lower occupational levels. Also, higher occupational status was found to be associated with preference for the younger, independent of age. It is suggested that, because of the heterogeneity of the male homosexual community, the degree of emphasis of youth will be found to vary with social setting.

Lymphocytic tumours of indeterminate nature: a 5-year follow-up of 98 conjunctival and orbital lesions.

Ninety-eight adnexal lymphocytic tumours of indeterminate nature have been followed up for at least 5 years. Both non-disseminating and disseminating tumours have either very similar or identical histopathological features. It is not possible to make a definitive diagnosis when the lesions are first seen, and a conclusion can be reached only after a prolonged follow-up. The nature of the non-disseminating tumours is unknown.

[Electron microscopic study of kidney biopsy specimens from children].

Investigation of kidney-biopsy taken from 17 children was carried out. The techniques used were: light-microscopic investigation of paraffin sections and ultrathin sections, electron microscopic investigation of the latter and basal-membrane measurements. According to the author's opinion electron microscopic investigation of kidney-biopsy is reasonable only in selected cases, representing special clinical and therapeutic problems. In cases of nephrosis syndrome electron microscopy helps in differentiation of the "mimimal lesion" and the early phase of the focal sclerotizing glomerular lesion. Further it gives good results in observation of mono- and olygosystemic diseases of the kidney. In the author's material electron microscopy contributed to more differentiated morphological diagnosis in 2/3 rds of the cases investigated. The authors join to the opinion of other investigators stressing that light-microscopical investigation should be completed by the light-microscopy of uktrathin scretions even then, when there are no possibilities of electonmicroscopical study.

[Permeability of post-ischemic aortic wall in rats].

Examinations were carried out in order to reveal details of process of the permeability damage, its degrea and fate of the plasma-substances getting into the vessel all. Abdominal aorta has been cross-clapped for one hour by the aid of a double ligature. In a recirculatory period from 1 hour to 10 days material serving for labeling of the plasma has been determined in the vessel using histochemical and microchemical methods. Colloidal iron was administered to animals one hour before removing the aorta. The highest quantity of colloidal iron in the aortic wall could be revealed after 24--48 hours of recirculation. By the 10th day the vessel wall contained physiological iron quantity. Colloidal iron administered on the second day of recirculation--when damage to permeability is most marked--in the early phase could be seen in the whole aortic wall. By the 7th day it could be detected only in the outer part of media and in the adventitia. Endothelium inhibits the flow of plasma-substances into the vessel wall, when they got through it, only elastic lamina form a temporary mechanical obstacle for transfusion.

[Effect of transient hypoxia on the permeability of rat aorta. Electron microscopic study].

Infrarenal part of the abdominal aorta in rats was closed out from the circulation by the aid of a doubled ligature. Changes of the permeability at different intervals after recirculation were investigated using colloidal iron as a labelling substance. The latter in an hour after recirculation could already be detected in the interendothelial junction and in the subendothelial space. The lesion of the permeability was most striking on the second day, and on the tenth day no more lesion could be observed. Increase of the permeability of the endothelium was paralelly followed by an inhibition of the media, which leads to significant ultrastructural changes.

[The india ink phagocytosis by monocytes and granulocytes during acute and chronic consumption coagulopathy].

During generalized intravascular coagulation (GIC) the polimerisation products of fibrinogen are phagocytized by the reticulo-endothelial system of the liver and spleen. Thus an inhibition of the clearance of RES could be detected in a progressed stage of the shock and GIC; this can also be represented by a decrease of India ink storage. In the present work the authors investigate the behavior of monocytes and granulocytes in the peripheral blood in GIC. Approximately 80% of cells will usually phagocytize and concentrate India ink granules, if heparinized blood mixed with India ink is incubated for two hours at 37 degrees C. A decrease of the India ink phagocytosis was detected in 6 patients and in 10 dogs during the shock. This observation corresponds to the behavior of hepatolienal RES during this condition.
