Abstract

The s.c. administration of cortisol to hamsters (50 mg/kg body wt/day for 4 days) produces a significant increase in maltase sucrase, alkaline phosphatase and leucineaminopeptidase activity in intestinal mucosa. Lactase activity is unaffected by cortisol. Gamma-glutamyltranspeptidase activity increases slightly in females but remains unchanged in males. Cortisol causes increase in proline and glycine absorption without changing the absorption of lysine.

摘要

给仓鼠皮下注射皮质醇(50毫克/千克体重/天,持续4天)会使肠黏膜中的麦芽糖酶、蔗糖酶、碱性磷酸酶和亮氨酸氨肽酶活性显著增加。乳糖酶活性不受皮质醇影响。γ-谷氨酰转肽酶活性在雌性中略有增加,但在雄性中保持不变。皮质醇会使脯氨酸和甘氨酸的吸收增加,而不改变赖氨酸的吸收。
