title: [Change in the rat liver microsomal monooxygenase system upon induction with phenobarbital in acute pancreatitis].
abstract: While injecting phenobarbital (PB) into the rats, on the second day of an experimental pancreatitis, cytochrome P450 2B1 and 2C6 activities were found, on the forth day of disease, as being considerably higher in comparison with data obtained in sham-operated control animals. On the tenth day of the acute pancreatitis (in three days upon having the induction canceled), activity of the cytochrome P450 isozymes was lower than that of control animals. Thus, the rats with acute pancreatitis, are characterized by an increased indycibility of liver monooxygenases. In addition, a release from induction (decrease of these activities upon having the induction canceled) proceeds faster than that in control animals.
