Abstract

Activities of several enzymes of glycolysis, glycerolphosphate cycle, TCA-cycle, beta-oxidation and pentose phosphate cycle were determined in pyloric caeca and ovaries of Asterias rubens during the reproductive cycle. 2. In the ovaries activities of CS and LDH were significantly decreased during ovarian stages 3 and 4, and those of GDH and GAPDH during stage 3 and 4, respectively. 3. In the pyloric caeca activities of GAPDH and LDH were lower in stage 4 and that of GDH in stage 3, whereas those of G6PDH and HOAD were increased in stage 3. 4. Changes observed in enzyme activities are discussed in relation to the reproductive cycle and to the multiple function of the pyloric caeca.

摘要

在生殖周期中，测定了红海星幽门盲囊和卵巢中糖酵解、甘油磷酸循环、三羧酸循环、β-氧化和磷酸戊糖循环的几种酶的活性。2. 在卵巢中，柠檬酸合酶（CS）和乳酸脱氢酶（LDH）的活性在卵巢发育第3和第4阶段显著降低，而谷氨酸脱氢酶（GDH）和甘油醛-3-磷酸脱氢酶（GAPDH）的活性分别在第3和第4阶段降低。3. 在幽门盲囊中，甘油醛-3-磷酸脱氢酶（GAPDH）和乳酸脱氢酶（LDH）的活性在第4阶段较低，谷氨酸脱氢酶（GDH）的活性在第3阶段较低，而葡萄糖-6-磷酸脱氢酶（G6PDH）和3-羟基酰基辅酶A脱氢酶（HOAD）的活性在第3阶段增加。4. 结合生殖周期和幽门盲囊的多种功能，讨论了观察到的酶活性变化。
