[The effect of chronic alcohol administration on specific features of the adenohypophysis in young animals in relation to the adult adenohypophysis].

We investigated chronic effects of ethyl alcohol on adenohypophysis in adult Wistar rats and adenohypophysis in development including the postnatal period up to 30 days. Morphological findings in gonadotropic, prolactin and follicular cells were compared. After three months of constant alcohol consumption in the form of a 15% liquid solution, vacuolization of gonadotropic cells which acquire the shape of a seal ring, as well as nodular hyperplasia of chromophobe cells combined with sparse somatotropic cells, occur in the adenohypophysis of adult male rats.

[Fatty material in the adrenal cortex 2 months after cessation of contamination].

The presence of lipid substances in the rat adrenal cortex was analysed two months after ending a one-month exposure to detergents. An increased quantity of neutral lipids was found throughout the adrenal cortex. An augmented triglyceride content was manifested to a higher degree in adrenocorticocytes.

[Fatty material in adrenal cortex cells 1 month after contamination with detergent].

The presence of fatty substances: neutral lipids, triglycerides, and phospholipids was detected in the adrenal cortex 30 days after the termination of detergent influence on white laboratory rats. We found that neutral lipids were of increased quantity in the glomerular, fascicular and reticular zone. Triglycerides were present in a greater extent in the entire cortex of animals which were subjected to the influence of detergents.

[Morphodynamic response of the pineal gland to an initial stress attack--the effect of morphine].

The possible participation of a stimulated ACTH secretion in the promotion of the pineal gland reactive response under conditions of injection stress was studied. Morphine was used as a pharmacological mimicry of the stress-induced ACTH outflow in the post-injection period of 10-45 min. In animals subjected to injection stress (administration of the physiological solution), in the 10-th min.

Morphodynamic reactive response of the pineal gland of rats chronically exposed to stable strong magnetic field.

Mature male Wistar rats were affected by a strong magnetic field of 0.70 T for 20 min per day for 2 weeks. A short distance between the electromagnet pole expansions allowed interposition of one restrained animal only.
