Abstract

Hepatic biotransformation was studied in microsomal (cytochrome P-450-dependent monooxygenase activities) and cytosolic (glutathione S-transferase activities) fractions from Japanese quail (Coturnix coturnix) and buzzard (Buteo buteo). Monooxygenase activities were not very different apart from a high 7-ethoxycoumarin de-ethylase activity in quail as compared to buzzard. Glutathione S-transferase activities were higher in quail than in buzzard. DP5 (a commercial mixture of PCBs containing 50% chlorine) produced a marked increase in monooxygenase activity from quail liver. In contrast, no induction was found in buzzard under the same conditions. Glutathione S-transferase activities were not modified in both species.

摘要

对鹌鹑(日本鹌鹑,Coturnix coturnix)和秃鹫(Buteo buteo)的微粒体(细胞色素P-450依赖性单加氧酶活性)和胞质溶胶(谷胱甘肽S-转移酶活性)部分的肝脏生物转化进行了研究。除了鹌鹑中7-乙氧基香豆素脱乙基酶活性高于秃鹫外,单加氧酶活性差异不大。鹌鹑中的谷胱甘肽S-转移酶活性高于秃鹫。DP5(一种含50%氯的多氯联苯商业混合物)使鹌鹑肝脏中的单加氧酶活性显著增加。相比之下,在相同条件下秃鹫未发现诱导现象。两种物种的谷胱甘肽S-转移酶活性均未改变。
