Abstract
Summary
Experiments on rats indicate that lithocholic acid-induced changes in the liver and choledochus, as well as the associated bile concrement formation, icterus, loss of body weight and mortality, are all inhibited or abolished by certain catatoxic steroids (PCN and CS-1) as well as by thyroxine and triiodothyronine. Prednisolone and triamcinolone have an opposite effect. Among the classic hepatic microsomal enzyme inducers, diphenylhydantoin is ineffective, and phenobarbital is much less potent than PCN or CS-1 in influencing the toxicity of lithocholic acid.
