代谢
... ICR品系雄性小鼠暴露于大约5%的正戊烷一小时,同时维持环境空气中的氧气含量在大约20%。然后收集它们的血液和肝脏组织,并通过GC和GC-MS进行分析。由此获得的代谢物是2-戊醇、3-戊醇和2-戊酮。...在存在NADPH生成系统的肝微粒体中,使饱和正戊烷或异戊烷水溶液的底物在37摄氏度下反应一小时。结果,产生了与暴露实验中获得的相同代谢物。因此,建议正戊烷...主要通过肝微粒体代谢。ICR品系的雄性小鼠连续四天喂食80 mg/kg b.w.的苯巴比妥,并暴露于正戊烷...一小时。这导致在正戊烷吸入...实验中2-戊醇和2-戊酮的量增加。...吸入实验。...
... Male mice of ICR strain were exposed to about 5% n-pentane for one hour while the oxygen in the environmental air was maintained at about 20%. Then their blood and liver tissue were collected and analyzed by means of GC and GC-MS. The metabolites thus obtained were 2-pentanol, 3-pentanol and 2-pentanone. ... In the presence of the NADPH-generating system liver microsomes were made to react to the substrate of saturated n-pentane or isopentane aqueous solution at 37 degrees C for one hour. As a result, the same metabolites were produced as obtained in the exposure experiment. It was therefore suggested that n-pentane ... /was/ metabolized chiefly by liver microsomes. Male mice of ICR strain were fed with 80 mg/kg b.w. of phenobarbital for consecutive four days and exposed to n-pentane ... for one hour. This resulted in an increase in the amount of 2-pentanol and 2-pentanone in the n-pentane inhalation .... inhalation experiment. ...
