[Selected anthropometric findings in women with disorders of glucose tolerance with hypertension].

In a group of 26 women with an impaired glucose tolerance anthropometric measurements of basic somatometric characteristics were made with special attention to the subcutaneous fat distribution and compared the findings with the healthy Czech population. Changes in body build, BMI, subcutaneous body fat distribution were evaluated and the causality of the relationship between blood pressure and gluteofemoral and abdominal obesity was investigated. From the author's observations ensues that in the group of women with impaired glucose tolerance overweight was recorded, as compared with the normal population, disproportions in the circumferences of the trunk and extremities, an excessive percentage of body fat, well developed muscles. In abdominal obesity a significant increase of the blood pressure and BMI was found.

Effect of prednisolone on the rat bone calcium, phosphorus and magnesium concentration.

Adult male rats were given prednisolone (Urbason solubile = 6-methyl-prednisolone) in doses of 4 mg/100 g body weight for 10, 20 or 30 days and its effect on the calcium, phosphorus and magnesium content of their femurs was studied. At all the given intervals a statistically significant decrease in the magnesium content of the bone was found; the calcium content was significantly reduced only in the first phase of the experiment (at 10 days).

T-lymphocytes detected by esterase technique in malignant tumours of the thyroid.

The authors studied the percentage of T-lymphocytes detected by means of acid non specific esterase technique in patients with malignant thyroid tumours. The lymphocytes were investigated in the punctates from the tumour as well as in the venous blood. The results were compared with those in simple goitres and in healthy controls respectively. It has been found that the percentage of T-lymphocytes in the tumours limited to the thyroid was significantly higher in comparison with those of disseminated tumours. In the venous blood of cancers with metastases the ANAE positive lymphocytes were decreased, when compared with thyroid cancers without spread as well as with healthy controls. After the operation the T-lymphocytes decreased in the blood to the values found in healthy people. The authors suppose that ANAE positive lymphocytes (corresponding to the T-lymphocytes) which play an important part in the anti-tumour cell defence might be used as a convenient criterion by which this aspect of immune state could be judged. Further experience will prove whether the presence of metastases could thus be assayed.

Effect of nifedipine on the adrenocortical and somatotrophic secretory reserve and TSH and thyroid hormone plasma levels.

The authors investigated the effect of one week's administration of therapeutic doses of the calcium antagonist nifedipine on the hormone homeostasis of clinically healthy subjects. The insignificant tendency towards an increase of the adrenocorticotrophic and somatotrophic secretory reserve and the unaltered levels of thyrotrophin, triiodothyronine and thyroxine rule out possible adverse side-effects of the administered therapeutic doses of nifedipine on the hormone balance of the mentioned systems. The authors discuss also the physiological impact of the assessed findings.
