| Popis: | 1. 1. Several pathways of drug metabolizing enzyme activity were measured in hepatic fractions of cattle, sheep, goats, chickens, turkeys, ducks, rabbits and rats. The pathways examined included the O -demethylation of p -nitrophenol, microsomal ester hydrolysis of procaine and glucuronidation of p -nitrophenol, and the cytosolic acetylation of sulfamethazine and sulfation of 2-naphthol. 2. 2. For most enzymatic pathways measured, goats were more similar to sheep (wether) than to cattle (steers). The exception was UDP-glucuronyltransferase activity, which was significantly higher for the goat than for any other species studied. 3. 3. Within the avian subset, the chicken and turkey were usually the most similar species. 4. 4. The activities of arylsulfotransferase isozymes III and IV were particularly low for the duck compared to the chicken and turkey. 5. 5. N -acetyltransferase activity was very high for rabbits and very low for sheep and goats. |
