[Effect of carbon tetrachloride on RNA metabolism in rat liver]

The effect of chronic CCl4 treatment on both the liver RNA content and 3H-uridine incorporation was studied. Comparison of morphologic and biochemical parameters allowed to define two successive stages of toxic process resulting in septal fibrosis. The most significant changes in the rat liver rapid RNA turnover were observed during the first 3 months of the toxic agent action. The metabolic disturbances were also manifest in both decreased RNA content and changes of nuclear-cytoplasmic interrelationships in the damage liver tissue.
