The available conventional remedies for the treatment of drug-induced liver diseases are highly inadequate and possess serious adverse effects; therefore, the development of new, effective drugs is considered necessary.

Pretreatment of rats with cobaltous chloride has been shown previously to reduce the content of cytochrome P-450 in the hepatic microsomal protein. This is accompanied by a corresponding decrease in substrate oxidation, e.g. ethyl morphine demethylation, in vitro. The present

Pretreatment of rats with phenobarbitone increased hepatic microsomal 7-methoxy-and 7-ethoxy-coumarin O-dealkylase activities. Pretreatment with beta-naphthoflavone increased only the 7-ethoxycoumarin O-dealkylase activity. The addition of metyrapone in vitro inhibited the O-dealkylations to different extents. Similar results were obtained with diphenyloxazole and

A simple HPLC-PAD-MS method was established to quantitatively analyse two spiroether isomers (cis-en-yn-dicycloether and trans-en-yn-dicycloether) and the main coumarin, herniarin, in chamomile herbs, simultaneously. By using this method, the contents of these three compounds in the flowers of two chamomile
