## 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

β¦ Synopsis
Isolated rat hepatocytes are used in many metabolic studies, but the viability of these cell preparations is often not adequately established. The present study shows that ATP content is a more reliable index of metabolic viability than trypan blue exclusion. At some of the low trypan blue exclusion levels quoted in the literature, a high percentage of cell preparations is likely to be nonviable by the criterion of ATP content. We suggest that ATP content measured on initial cell preparations and at the end of all incubation procedures is essential for establishing cell viability for metabolic studies on isolated hepatocytes.

A method for preparing suspensions of hepatocytes with long-term viability is described. Its originality lies in the use, after conventional preparation, of a Percoll density gradient centrifugation which allows a complete and rapid separation of cell debris and released proteases from the intact he
The isolated hepatocyte preparation has become an increasingly popular system for studying xenobiotic metabolism, and there is a need for methods of determining metabolic activity. Described here is a simple and sensitive radiometric assay for barbiturate iV-demethylase activity in the isolated hepa
