abstract：BACKGROUND/AIMS:Isoniazid (ISO) has been reported to inhibit the hepatic aldehyde dehydrogenase (ALDH) and to cause a disulfiram (DIS)-like reaction, albeit there are no reports demonstrating increased blood acetaldehyde levels after co-administration of ISO with alcohol. The aim of our study was to clarify whether the...

abstract：:Previous investigations demonstrated that CYP2D16 was expressed at high levels in guinea pig adrenal microsomes. The studies presented here were done to determine whether adrenal metabolism of bufuralol (BUF), a model CYP2D substrate, was similar to that in the liver. Guinea pig adrenal microsomes converted BUF to 1'-...
