    Notizen: Abstract Oral administration of isotretinoin (13-cis-retinoic acid) (6 mg/kg per day), 0.05% hexachlorobenzene (HCB) or both drugs simultaneously for 10 days to female Wistar rats caused a statistically significant induction of aminopyrine-N-demethylase (ADM), 7-ethoxyresorufin-O-deethylase (7-ERO-D) and erythromycin-N-demethylase (EMDM) in the liver microsomes. Oral administration of isotretinoin alone or together with HCB induced a marked induction of 7-ERO-D and EMDM in the skin. Administration of isotretinoin alone for 60 days resulted in the induction of EMDM in the liver microsomes, and in combination with HCB caused a statistically significant induction of all hepatic isozymes. HCB alone caused a marked induction of only 7-ERO-D in the skin. These results clearly show that oral isotretinoin is capable of inducing hepatic and cutaneous microsomal P-450-dependent catalytic activities. It remains to be elucidated whether the induction of these enzymes is of importance for the therapeutic action of isotretinoin.

    Notizen: Abstract Adult female Wistar rats (n=48) divided into four groups of 12 were treated orally with 3 mg/kg per day thalidomide, a 0.05% hexachlorobenzene (HCB) — containing diet, with both drugs together and with the vehicles (controls) over periods of 10 and 60 days. The protein and P450 contents and the activities of amino-pyrine-N-demethylase (ADM) and 7-ethoxyresorufine-O-deethylase (7-ERO-D) were determined in the liver microsomes. The activity of 7-ERO-D was also determined in the skin microsomes and total porphyrins were measured in the urine of the animals. Thalidomide increased the hepatic P450 content, caused distinct changes in the activities of the hepatic and cutaneous microsomal isozymes, modified their induction by HCB and inhibited the porphyriogenic activity of HCB. These findings indicate an interaction between thalidomide and HCB with regard to their effects on the P450 isozymes and the metabolism of porphyrins.
