Abstract

High activity of cystathionase was present in rat liver but only low amounts of activity in rat brain during development. Triamcinolone had no effect on liver cystathionase activity in foetuses but increased the enzyme activity significantly in postnatal rats. l-Thyroxine decreased liver cystathionase activity significantly in newborn rats; administration of pyridoxal 5'-phosphate did not prevent this effect. l-Methionine significantly increased liver cystathionase activity in newborn rats.

摘要

在发育过程中,大鼠肝脏中胱硫醚酶活性较高,而大鼠大脑中的活性较低。曲安西龙对胎儿肝脏中的胱硫醚酶活性没有影响,但能显著提高出生后大鼠的该酶活性。左旋甲状腺素能显著降低新生大鼠肝脏中的胱硫醚酶活性;给予5'-磷酸吡哆醛并不能阻止这种作用。左旋甲硫氨酸能显著提高新生大鼠肝脏中的胱硫醚酶活性。
