title: [Indices of RNA metabolism in the brain stem of rats under superlethal exposure to ionizing radiation].
abstract: A study was made of the content of hnRNA, nuclear poly(A) RNA and biosynthesis of rlnRNA in truncus cerebri of rats divided into 3 groups by the forced swimming test 6-8 min and 60 min after a short-term exposure to sparsely ionizing radiation of 100 Gy. The observed changes in the nuclear RNA metabolism can subsequently lead to the impairment of the synthesis of proteins required for normal functioning of CNS, and to the development of CNS syndrome.
