[The nervous system and the genetic apparatus of cells]

Electric stimulation of paraventricular hypothalamic nucleus results in intensification of RNA synthesis in rat brain. Content of acid proteins and RNA in liver and brain chromatin of geese changes in the period of sexual activity controlled by hypothalamus. With long introduction of hydrocortisone content of non-histone proteins of chromatine and RNA as well as total content of RNA in rat liver cells increases. These and other facts confirm the supposition that the central nervous system has an influence on the function of organs and tissues by means of genetical apparatus of cells.
