title: Cyclic nucleotides levels in the liver of rats treated with CCl4.
abstract: Treatment of rats with two different doses of CCl4 (respectively 2.5 and 0.5 ml/kg body wt. intragastrically) is followed by a rapid increase in the cAMP content of the liver. With 0.5 ml of CCl4, the increase occurs as early as 30 min after poisoning, namely about 4-5 h before the onset of triglyceride accumulation in the liver. The maximum increase has been at 6 h after administration of the hepatotoxin. In both experimental conditions, normal values are recovered only after 36-48 h. cGMP level appears unmodified during the whole observation period. Therefore the ratio cGMP/CAMP decreases consistently. The ATP level decreases significantly between 2 and 12 h. The increase in liver triglycerides level after CCl4 can be also a consequence of an impairment of microtubule function, leading to a decreased release of lipoprotein micelles from hepatocytes into the blood stream.
