[The effect of peptide-type epiphyseal hormones on the functional activity of the human thyroid in vitro. The action of epiphyseal peptides on the accumulation of cyclic nucleotides in the normal human thyroid and on its secretory activity].

Effects of pineal peptides on the accumulation of cyclic nucleotides of the human thyroid and its secretory activity were analysed on the basis of the data obtained after operation from patients with nodular euthyroid goiter) incubated with Epithalamine and Epiphisan, were studied. It was shown, that pineal peptides not only inhibited thyroid secretion function and cAMP accumulation, but also acted as modifiers of TSH stimulatory effects.

[The effect of peptide-type epiphyseal hormones on the functional activity of the human thyroid in vitro. The characteristics of the action of epiphyseal peptides on the accumulation of cyclic nucleotides in the thyrotoxic thyroid and on its secretory activity].

Reaction of the human TSH-sensitive and TSH-refractory thyroid, obtained from patients with hyperthyroidism, on pineal peptides was studied in vitro. It was shown, that pineal peptides (Epythalamine) are inhibitors of cAMP accumulation and hormone release only of normal and TSH-sensitive thyroid, but are ineffective in case of TSH-refractory thyroid. Thus, pineal peptides are modulators of specific TSH effect.

[Radioimmunologic research in the complex assessment of thyroid status in primary hypothyroidism].

Radioimmunoassay data on the determination of the plasma levels of free and bound forms of thyroid hormones and TSH in various types of primary hypothyrosis were analyzed. The variability of analyzed indices was revealed; changes in the thyroid status according to the results of hormonal investigations were more noticeable in idiopathic hypothyrosis, the least noticeable in patients with hypothyrosis operated on for diffuse toxic goiter. Changes detected in patients with severe-type hypothyrosis did not depend on the type of disease.

[Seasonal dynamics of adrenal mineralocorticoid function in rats].

Seasonal peculiarities of adrenal mineralocorticoid function and some aspects of its regulation have been studied in experiments on male Wistar rats. It has been found that changes in aldosteronemia and aldosteronurea were maximum in spring and minimum in summer--autumn period. The highest indices of aldosterone metabolic clearance from plasma were observed in winter with the following progressing decrease and a small increase in autumn. The diagram of melatonin content in the epiphysis of experimental rats was the same. Hypokinesia attenuated aldosteronurea during all the investigation periods, preserving the character of aldosterone secretion year curve. PRA level changed irrespective of aldosterone levels in plasma and urea. It has been concluded that a certain stability of mineralocorticoid adrenal function seasonal rhythms has different regulating effects.

[Interaction of prostaglandin E2 with receptors and their effect on adenylate cyclase activity in human thyroid tissue].

The investigations have been performed on thyroid tissue excised from patients suffering from euthyroid goiter and thyrotoxicosis. The study of thyroid thyrotoxic tissue has revealed the decrease in the number of free receptors to 3H-PGE2 caused by the enhanced production of receptor-endogenous PGE2 complexes whose level in thyrotoxic tissue was significantly higher than in euthyroid tissue. PGE2 and GppNHp had a pronounced stimulating effect on adenylate cyclaze activity both in euthyroid and thyrotoxic tissues, with enzyme sensitivity to stimulating effects considerably increased in the latter case.

[Seasonal characteristics of the effect of melatonin on thyroid function].

Changes in pituitary-thyroid axis sensitivity to bioactive component of pineal gland, melatonin, have been detected. In winter (short days) melatonin (100 micrograms/100 g of rat body weight) decreased T3 T4, TSH content and 131I uptake by thyroid tissue. However, it was noted that in summer (long photoperiod) the same injection caused suppression of T3 plasma level and 131I uptake ability of the thyroid gland, with T4 and TSH blood levels remaining significantly increased.
