Effect of various steroids on microsomal aliphatic hydroxylation and N-dealkylation

In rats, pretreatment for three days with spironolactone, norbelethone and ethylestrenol diminished the depth of anesthesia induced by hexobarbital, increased its aliphatic hydroxylation by liver microsomes and enhanced its elimination from blood. Similar pretreatment also enhanced the N-dealkylatio...

Beschreibung
Zusammenfassung:	In rats, pretreatment for three days with spironolactone, norbelethone and ethylestrenol diminished the depth of anesthesia induced by hexobarbital, increased its aliphatic hydroxylation by liver microsomes and enhanced its elimination from blood. Similar pretreatment also enhanced the N-dealkylation of aminopyrine by liver microsomes, causing a parallel decrease in its blood concentration. Progesterone was inactive against hexobarbital but slightly increased the production of 4-aminoantipyrine by liver microsomes.
