A New Method for Early Diagnostics of Pathological States under the Action of Physiologically Active Substances with Genotoxic Properties upon Organism

Abstract

The article is dedicated to the new method for early diagnostics of pathological conditions under the action of physiologically active substances with genotoxic properties. The method allows the evaluation of microsomal system of the liver under the action of xenobiotic alkylating type and the condition of microsomal oxidiation system in vivo. It is supposed to asses preliminary the norm of the reaction of organism (phenotype of bio-object) by the intensity of microsomal oxidiation during the study of the toxicological characteristics of physiologically active substances influencing the organism at low doses. The method includes the characteristics of hereditary intensity of epoxidiation (hydroxyliation) reactions of metabolism. Carbamazepine is used as a pharmacological probe. The article formulates the definition of the concept of norm, threshold for the harmful effect and prepatological state of organism.
