[Various characteristics of catecholamine metabolism in thyrotoxicosis].

Catecholamine metabolism was studied and compared with thyrotoxicosis in 205 patients, depending on the age, illness severity and therapy type. Analysis of the data obtained allowed one to observe some peculiarities of catecholamine metabolism in thyroid hyperfunction: i. e.

[Adrenocorticotropic and somatotropic functions of the pituitary gland in juvenile thyrotoxicosis].

The adrenocorticotropic (ACT) activity of the hypophysis (according to the blood 11-HCS level) was studied in 27 female patients suffering from thyrotoxicosis, aged from 16 to 24 years (19 with moderately severe and 8 with severe form) and in 7 healthy girls. The ST activity of the hypophysis was ascertained in 11 patients by the blood STH content before and after the insulin hypoglycemia. The metopyron test was also carried out in 6 patients.

[Reactivity of the sympathetic-adrenal system in juvenile thyrotoxicosis].

In examination of patients with thyrotoxicosis, aged from 14 to 24 years, there was revealed a reduction of the activity of the mediatory link of the sympathico-adrenal ssystem without any connection with age, the severity and duration of the disease, and also with the efficacy of drug therapy. The functional test with insulin in patients with thyrotoxicosis permitted to detect definite reserve possibilities of the adrenergic regulation intensified with increased duration of the disease and with advance of the patient's age, but not with increased severity of the disease. The insulin test offered a possibility of assessing the sympathico-adrenal system reactivity in cases of different degree of the disease compensation.
