Abstract
- Ascorbic acid, diamide and N-ethylmaleimide inhibit Na+ + K+-ATPase activity in toad corneal epithelium. 2. Ascorbic acid, diamide and N-ethylmaleimide increase alpha-aminoisobutyric acid accumulation in this tissue. 3. The effects of these compounds on corneal amino acid and ion transport are not mediated through alterations in Na+ + K+-ATPase activity.
摘要
- 抗坏血酸、二酰胺和N-乙基马来酰亚胺抑制蟾蜍角膜上皮中的Na⁺+K⁺-ATP酶活性。2. 抗坏血酸、二酰胺和N-乙基马来酰亚胺增加该组织中α-氨基异丁酸的蓄积。3. 这些化合物对角膜氨基酸和离子转运的作用并非通过改变Na⁺+K⁺-ATP酶活性介导。
