A comparative analysis of the obtained material for determining the duration and severity of trace cytochemical reactions developing in the retina and visual cortex of rats in response to course influence of marepolimiel injections (21 per day, 0.1 ml/kg), cysteine (10 days, 100 mg/kg) and ascorbic acid (10 days, i/m, 15 mg/kg) has conducted. The criterion for evaluating the metabolic means was as follows: optical density of RNA, NH2-groups and thiols. Intensity drug action is characterized by a certain sequence: ascorbic acid — cysteine — marepolimiel.
