| abstractText | Studies were carried out in order to find a sensitive in vitro model with which to investigate cocaine-mediated hepatotoxicity. Precision-cut liver slices were prepared from: human, domestic pig, New Zealand white rabbit, Sprague-Dawley (S/D) rat, and two mouse strains (DBA/2Ha and ICR). The rationale for the choice of these species was that information on in vivo effects of cocaine was available in the literature. Slices were cultured for up to 6 h in the presence of 0-5 mM cocaine. Indices of toxicity consisted of K+ retention and Ca2+ uptake. Minimal effects and no clear dose-response relationships were observed. In addition to the studies with non-pretreated animals, liver slices were prepared from DBA/2Ha and ICR mice, both induced by housing on pine shavings, and phenobarbital pretreated Sprague-Dawley rats. The induced ICR mouse and rat were approximately 3 times more sensitive to cocaine-mediated hepatotoxicity. The following order of sensitivity to cocaine-mediated hepatotoxicity was established: induced rat = induced ICR mouse much greater than induced DBA/2Ha mouse = rabbit = uninduced ICR mouse = uninduced DBA/2Ha mouse = uninduced rat greater than pig = human. |
