[Sensitivity of the pituitary-ovarian system of animals to the nonhormonal preparation RL-S].

A hypophysis-ovarian system of barren cows was shown to be highly sensitive to the effect of the preparation RL-S. The preparation possessing a simple chemical structure, proved to regulate the functional activity of endocrine glands. After treatment with the preparation RL-S concentration of estradiol was increased 1.

[Effect of RL-175 on testosterone and corticosterone levels in the plasma of male albino rats].

After feeding of male rats with the chemical preparation RL-175 a 1.5-fold increase in the testosterone content and more than 2-fold increase of corticosterone were found in blood as compared with control values. Considering that hypothalamus less than the front zone of hypophysis greater than and the endocrinal glands are the most important tissues in sexual and adaptational regulation, the drug RL-175 can be used for treatment of the diseases developing with age, i.

[Cerebral contusions in injuries with fractures of the bones of the skull in children].

The authors analyzed 205 cases of skull fractures in children. Linear, depressed and comminuted skull fractures as well as ruptures of the cranial commissures were revealed. Skull fractures in children were characterized by specific features depending on the age, type of fractures and the mechanism of injury and were always attended with contusions of the brain.

[Clinico-biochemical parallels in neurotoxicoses in children].

The authors present the results of examining the plasma lipids in 62 children with an infectious neurotoxic syndrome. The children were suffering from acute respiratory viral infections, lobular pneumonia, or intestinal infections. Hyperlipidemia and dysphospholipidemia were revealed: the former was due primarily to a rise of the content of non-saturated fatty acids and triglycerides, and the latter to a drop of the lecithin and cephaline levels.
