[The functional activity of thyroid of male rats with acute and mild streptozotocin diabetes].

The type 1 diabetes mellitus (DM1) and dysfunction of thyroid are the most common endocrine diseases, which are interrelated. However, the molecular mechanisms of thyroid dysfunction in DM1 and the role of adenylyl cyclase signaling system (ACSS) in this process remain poorly understood. Typically for studying etiology and pathogenesis of thyroid diseases in DM1 the models of acute DM1 induced by high doses of streptozotocin (STZ) are used.

[The influence of two-month treatment with bromocryptine on activity of the adenylyl cyclase signaling system in the myocardium and testes of rats with type 2 diabetes mellitus].

One of the common complications of type 2 diabetes mellitus (DM2) are cardiovascular diseases and dysfunctions of the reproductive system, indicating the urgency of developing new approaches to their correction. Last years for the treatment of DM2 began to use bromocryptine (BC), the agonist of type 2 dopamine receptors, which not only restores the energy metabolism, but also prevents the development of cardiovascular diseases. However, the mechanisms and targets of BC action are poorly understood.

Androgen deficiency in male rats with prolonged neonatal streptozotocin diabetes.

We studied the diurnal dynamics of testosterone concentration in male rats with 240-day neonatal streptozotocin-induced diabetes mellitus, which is similar to human type 2 diabetes mellitus. We also studied the effects of intranasal administration of luliberin on testosterone level and the regulation of activities of adenylate cyclase and stimulatory G-proteins in the testicles of diabetic and intact animals by human chorionic gonadotropin. In rats with neonatal diabetes, a decrease in the mean diurnal level of testosterone and its morning rise were observed.
