| Abstract: | Paraquat action on glutathione reductase activity and intratissue distribution in the liver of intact rats and also in the animals antenatally treated with the given herbicide was studied by some biochemical and histochemical methods. It has been ascertained that paraquat injection into intact animals promotes the increase in the intracellular enzyme level, development of glutathione reductase staining of hepatocyte nuclei, diffuse distribution of the staining along the lobe. In rats antenatally treated with paraquat acute priming does not induce glutathione reductase. In these conditions a mosaic distribution of this enzyme is observed in the hepatic tissue. |
