Abstract
A single injection of cortisone or thyroxine to 8-day-old suckling mice initiates a temporary decrease of lactase activity. On the contrary, 3 injections of cortisone or thyroxine provoke a significant increase of lactase activity. It appears that the mechanism which controls the postnatal development of lactase in suckling animals is more complex than expected.
摘要
对8日龄的哺乳小鼠单次注射可的松或甲状腺素会引发乳糖酶活性的暂时下降。相反，注射3次可的松或甲状腺素会使乳糖酶活性显著增加。看来，控制哺乳动物出生后乳糖酶发育的机制比预期的更为复杂。
