Abstract
The 5alphaH (A : B trans) and 5betaH (A : B cis) steroids are equipotent in inducing delta-aminolevulinic acid synthetase and porphyrin accumulation in chick embryo liver cells maintained in serum-free culture medium. Thus there is no specific steric requirement for porphyrin-inducing activity in steroids.
摘要
5αH（A:B反式）和5βH（A:B顺式）类固醇在无血清培养基中培养的鸡胚肝细胞中，诱导δ-氨基乙酰丙酸合成酶和卟啉积累方面具有同等效力。因此，类固醇中诱导卟啉的活性没有特定的空间要求。
