Natrium, potassium, cholesterol and total free 11-hydroxycorticosteroids variations in thymectomized and thymic extract treated rats.

The authors investigated the effect of thymectomy and TP2 thymic polypeptide extract administration on total, esterified and free cholesterol in the plasma and the adrenals, as well as on plasma Na and K and plasma free total 11-hydroxycorticosteroids. The results showed that total, esterified and free cholesterol decrease in the adrenals by 23.20%, 28.

Effect of a melatonin-free extract from bovine pineal on plasma and urinary steroids and on serum prolactin in hirsute amenorrheic adolescents.

Basal and post-suppressive dexamethasone (dxm) levels of some urinary androgen metabolites, plasma testosterone (T), 17 hydroxyprogesterone (17 OHP) and of basal serum prolactin were determined in 34 hirsute amenorrheic adolescents aged 13-17 in whom a five day course of bovine pineal extract (4 ml a day i.m.) was instituted.

Studies of the reproduction function in hyper- and hypoadrenocorticism.

The investigation was carried out on 66 patients with hypo- or hyperfunctional syndromes of adrenocorticism, hospitalized and treated by our team. The patients were grouped into 5 lots according to their diseases. Lot one consisted of 34 female patients with Cushing's syndrome, lot two of 10 males with Cushing's syndrome, lot three of 10 males with Addison's disease and lot four, of 6 females with androgenic hypercorticism.

The role of the renin-angiotensin system in arterial hypertension in hypercorticism.

The authors have studied on 25 cases of hypercorticism, one of the mechanisms of producing arterial hypertension, the renin-angiotensin system. The study showed that in only 20% of the cases plasma renin activity was high whereas in the remaining 80% other mechanisms were responsible for the hypertension. In the cases in which the plasma activity of renin was high, by studying the changes in the value of electrolytes we were able to derive some understanding of the mechanism of action of the RA2A system.

[Severe arterial hypertension due to chronic constitutional hyperadrenalism. Splanchnic sympathectomy and left adrenal medulla sclerosis with 40 percent sodium salicylate (result after 3 years--genetic chemosurgery)].

The case is presented of a male patient hospitalized for severe arterial hypertension determined by chronic constitutional hyperadrenalism. Splanchnic-sympathectomy was performed, associated to medullar sclerosis of the left adrenal with 40% sodium salicylate (genetic chemical surgery). The results after 3 years were good, both clinically and paraclinically.
