[Indicators of circulation, respiration and muscle strength in puberty].

Measure of vital capacity, grasping strength, stature, weight, and systolic and diastolic blood pressure as well as pulse frequency, both before and after exertion, were made on 165 twelve to fourteen year-old boys and girls from Hamburg schools-(Gymnasium). Age and sex showed significant mean differences on these measures, but not constantly so. Analysis of variance indicated some influence of age and sex, but these variables explained only a small part of total variance of physiological measures.

Relations between sex hormone level and characters of hair and skin in healthy young men.

Total testosterone and dihydrotestosterone in blood serum as well as free testosterone in saliva were determined by radioimmunoassay in 110 healthy young men. The results were compared with the development of terminal hair on the trunk and limbs, with the disposition to balding and with the disposition to acne. No significant correlations were found between terminal hair development and absolute androgen levels; however, some significant values were observed in the case of the metabolic rate of dihydrotestosterone/testosterone and the proportion of free to total testosterone.

Relations between anthropometric characteristics and androgen hormone levels in healthy young men.

Inter-individual correlations between androgen hormone levels and anthropometric features were computed using data from a sample of 110 healthy young men. Radioimmunoassays were used to determine the total testosterone and dihydrotestosterone in the serum and the free testosterone in the saliva. The 58 body measures encompassed the head, trunk and extremities in terms of their length, breadth and circumference.

Androgen levels and components of aggressive behavior in men.

Serum concentrations of testosterone (Tser), 5 alpha-dihydrotestosterone (DHT), and free testosterone (Tsal) in saliva were determined in 117 healthy young men between the ages of 20 and 30. A battery of standardized tests and projective techniques were administered simultaneously in order to measure various components of aggression, including sexual aggressiveness. All three androgens show reliable positive correlations with self-ratings of spontaneous aggression.

Sex hormones and cognitive functioning in men.

Blood and saliva samples were obtained from 117 healthy young men, following which radioimmunoassays were used to determine the serum concentrations of testosterone (Tser), 5 alpha-dihydrotestosterone (DHT), and the level of free testosterone (Tsal) in the saliva. The cognitive functioning was determined by five spatial and six verbal ipsative test scores, reflecting intra-individual variance in the performance of these tasks, independent of the person's general level of achievement. Within the normal physiological range of androgen levels--especially Tser and to a lesser extent DHT and Tsal--showed a significantly positive correlation with measures of spatial ability and field dependence-independence and a significantly negative correlation with measures of verbal production.

Relations between sex hormone levels and sexual behavior in men.

Using a sample of 33 healthy young men, 6 blood samples were obtained in the course of 2 weeks, and testosterone, dihydrotestosterone, and estradiol levels determined. The amount of free testosterone in the saliva was also ascertained for 23 of the subjects. All participants kept a daily record of their sexual activity during the investigational period.

Comparisons of the intra- and inter-individual variability in sex hormone levels of men.

Six blood samples were taken from each of 33 healthy young men during the course of 2 weeks. From these, the testosterone, dihydrotestosterone, and oestradiol levels were determined. In addition, free testosterone was measured using saliva samples obtained from 23 of the subjects.

Sex hormones and stress in the human male.

Six blood samples were obtained from each of a group of 33 healthy males between the ages of 19 and 31, following which radioimmunoassays were used to determine the serum concentrations of testosterone (Tser), 5 alpha-dihydrotestosterone (DHT), and estradiol (E2). In addition, the free testosterone (Tsal) was also measured using saliva samples provided by 23 of the subjects. A questionnaire of our own design was administered together with the Sixteen Personality Factor Questionnaire (16 PF-Test) at the time of the first blood sample in order to check the long-term stress loads of our subjects as well as their abilities to deal with stress.

[Relations between blood polymorphism and uterine carcinoma].

In a study of 63 female patients with cervical carcinoma and 37 with corpus carcinoma (all patients from Hamburg), polymorphisms of the blood were determined, which have not previously or only rarely been studied in such patients. Comparisons with a control group revealed no significant differences for the MNSs, P, Jk, SEP, PGM, GPT, EsD, Hp, Gc, and Gm systems. The patients with corpus carcinoma, however, exhibited a lesser frequency of Ccee and an increased frequency of homozygotes in the Fy system.

[Transferrin types in the Dama (Southwest Africa)].

The transferrin type of 238 Dama serums was determined and an estimate made of the gene frequencies. Using the SANGHVI method, the distribution of the transferrin types of the Dama was compared with 53 African populations south of the Sahara. The comparison demonstrates the great dissimilarity of the Dama to the Khoisanide tribes and confirms--at least in part--the results of polysymptomatic affinity comparisons of the Dama with other African populations.

[Investigations of constitution in patients with primary amotio retinae (author's transl)].

In 53 mostly old patients with Amotio retinae (37 femeles and 16 males) the type of constitution, meaning the placement in the variation grade from leptomorph to pyknomorph, was determined by biometrical methods (discrimination analysis). The calculated mean values of the group of patients were compared to the results of a leptomorph and a pyknomorph group as well as those of a control group. On a linear scale from lepto- to pyknomorph the patients could be placed between the controls and the pyknomorphs.

Blood and serum protein groups of the dama of South-West Africa.

The phenotype and gene frequencies of the following polymorphisms are given for the blood samples taken from 448 adults of the South-West African Dama Negro tribe: ABO (with sub-groups), MN, Rh, K, Hp, Gc, Gm(1,2,b), InV(1). The frequencies are discussed in comparison with other African samples and a multivariate comparison between series from south-western Africa is conducted. The Dama prove to be relatively independent.
