## Abstract Chloroquine is a synthetic quinoline being used as an antimalaria and antirheumatoid agent. Several cases of hepatotoxicity have been reported with the use of chloroquine. However, the mechanism(s) of its hepatotoxic effect is unknown. The purpose of this study was to investigate the cy

✦ Synopsis
Sanguinarine, chelerythrine and fagaronine were examined for hepatotoxic effect. Administration of sanguinarine and chelerythrine (10mglkglday; i.p.) produced marked parenchymal injury not found in the livers of fagaronine treated rats. In chronic administration of sanguinarine (0.2 mgFgl56 days; i.p.) degeneration and necrosis were not observed in the liver. The effect of the alkaloids was tested by enzyme leakage (LDH and ASAT) and changes in glutathione levels in isolated rat hepatocytes. Sanguinarine produced the greatest toxicity followed by lesser toxicity in the case of chelerythrine while no toxicity was displayed with fagaronine. These effects correlate with pK,. values for pseudobase formation. Finally, no increased lipid peroxidation or mitochondria1 membrane damage were found.

The protein kinase C (PKC) family of isoenzymes plays a key role in the regulation of hepatocellular secretion. The hydrophobic and cholestatic bile acid, taurolithocholic acid (TLCA), acts as a potent Ca++ agonist in isolated hepatocytes. However, its effect on PKC isoforms has not been elucidated.
taken up primarily through a sodium-dependent transport system (1-3). Organic anions such as indocyanine green, along with unconjugated bile salts, appear to be taken up by a separate sodium-independent transporter (2, 4, 5). The two carriers have been tentatively identified as a 48-kD protein for s
The effect of vasopressin (VP) on canalicular function and hepatocellular morphology, with particular regard to actin cytoskeletal organization and the concomitant plasma membrane bleb formation, was studied in isolated rat hepatocyte couplets. VP induced the concentration-dependent formation of mul
