[Interdependence between hormonal disorders, staging and degree of malignancy of prostatic gland cancer. 2].

The aim of this study was to estimate the relations between oestrogen, progesterone, prolactin (PRL) and gonadotrophin levels and the degree of advancement as well as that of malignancy of carcinoma of the prostate. Serum LH and FSH levels were determined under baseline conditions and after stimulation with LH-RH. In patients with metastases and in less differentiated forms of carcinoma the level of oestradiol (E2) was significantly higher. The testosterone/oestradiol ratio was notably lower in patients without metastases and in more differentiated forms. Serum progesterone was significantly higher in less differentiated forms of carcinoma. The concentration of LH in response to the administration of LH-RH was significantly higher in patients with metastases. Measurement of hormone levels at certain stages in the course of carcinoma of the prostate may be of practical value in the choice of appropriate hormone treatment.

The effect of metoclopramide, TRH and L-dopa on prolactin secretion in pituitary adenoma and in "functional" galactorrhoea syndrome.

The degree of autonomy in prolactin secreting pituitary adenomas and also prolactin secretory reserve in cases with suspected functional galactorrhea syndrome was evaluated with the use of metoclopramide, TRH and L-DOPA. It was found that in patients with pituitary adenoma the basal prolactin (PRL) level often exceeded 150 micrograms/l and the response to stimulation with TRH and/or metoclopramide was markedly diminished or even nonexistent, while the response to L-DOPA was usually retained. In patients with galactorrhoea and/or amenorrhoea, with normal skull X-ray the basal PRL level was either normal or moderately raised but the response to stimulation was various; mostly it was excessive, it was sometimes normal, but in some other cases it was markedly diminished as in patients with adenoma. In the author's opinion the so-called "functional disorder" of prolactin secretion is mainly hyperresponsiveness to stimulation, whereas the basal PRL level in those cases is usually normal or only intermittently raised. In the cases with a moderate hyperprolactinaemia, especially if it appears to be constant, and the response to stimulation is diminished or none at all, we suspect a pituitary microadenoma. Finally, there are rare cases of galactorrhoea with normal basal PRL and normal response to stimulation, in which the sensitivity of the mammary PRL receptor is probably increased. We suggest therefore that the above mentioned PRL stimulation tests may help in distinguishing between tumoural and functional hyperprolactinaemia.

Endocrinology of pregnancy. I. Denominations of concentrations of triiodothyronine, thyroxine, effective thyroxine, thyreotrophin and growth hormone in normal pregnancy, labour and in cord blood.

Concentrations and activities of the following agents were estimated: triiodothyronine (T3), thyroxine (T4), effective thyroxine (ETR), thyreotrophin (TSH), and growth hormone (HGH). Blood samples were collected in pregnancy, labour and from the umbilical cord of the newborns. It was demonstrated that in normal pregnancy the concentrations of T3, ETR, and TSH did not differ significantly from the values considered as normal in non-pregnant women. The concentration of T4 was distinctly higher in the course of pregnancy (139 to 157 nmol/l versus 110 nmol/l in non-pregnant subjects). The HGH concentration increased during pregnancy from 5.6 to 14.3 micrograms/l. The cord blood demonstrated comparable values of ETR and HGH and in half of the cases of TSH also with those observed in the mothers. In the other one half of the cases, TSH activity was fourtimes higher than the material value. The T3 and T4 were lower than values in the mothers. The results presented are the normal values for further planned investigations of endocrinology of pregnancy, especially for studies into course of pregnancy in women who work in noxious conditions.
