Abstract
- Effects of acute starvation on enzymes of carbohydrate metabolism were determined in rat submandibular and parotid glands. 2. Activities of glycolytic enzymes were high in submandibular gland, but those of pentose phosphate pathway and glycogen metabolism were high in parotid gland. 3. Enzyme activities were lowered by acute starvation. Refeeding the rats with solid diet restored the enzyme activities, but with liquid diet, only partial recoveries were found in submandibular gland.
摘要
- 在大鼠颌下腺和腮腺中测定了急性饥饿对碳水化合物代谢酶的影响。2. 颌下腺中糖酵解酶的活性较高，而腮腺中磷酸戊糖途径和糖原代谢的酶活性较高。3. 急性饥饿使酶活性降低。用固体饲料重新喂养大鼠可恢复酶活性，但用液体饲料时，颌下腺中仅发现部分恢复。
