Stimulating Effect of the Roots of Panax ginseng C. A. MEYER on the Incorporation of Labeled Precursors into Rat Liver RNA

Abstract

The in vivo administration of extract of the roots of Panax ginseng C. A. MEYER increased the incorporation rate of labeled precursors into liver nuclear RNA at 4 hr and into cytoplasmic polysomal RNA at 5.5-6.0 hr after a single dose intraperitoneal injection in a rat. The incorporation rate was directly dependent on the amount of a fraction obtained by partial purification. The increased specific radioactivity of the liver RNA is not due to the change in the pool size of endogenous acid-soluble nucleotides.
