In this experimental study, three sorts of grafts (venous flap, composite graft and axial flap) were created. According to the results of relative contents of LD1, and LD5 in these grafts, the conclusion was drawn: Oxyhemoglobin remaining in the grafts maintained normal carbohydrate metabolism within 24 hours postoperatively. 48 hours later, aerobic oxidation of carbohydrate abated but kept in a considerable level in venous flaps due to the existence of venous blood. 72 hours after the operation, aerobic oxidation of carbohydrate in venous flaps reached its lowest point. At this point, the venous flaps would necrose gradually unless a new nourishing source be obtained. From the 4th postoperative day, aerobic oxidation of carbohydrate of venous flaps began to increase. By the 7th day, aerobic oxidation of carbohydrate of venous flabs returned to normal.
在本实验研究中，制作了三种移植物（静脉皮瓣、复合移植物和轴型皮瓣）。根据这些移植物中LD1和LD5相对含量的结果，得出结论：移植物中残留的氧合血红蛋白在术后24小时内维持正常的碳水化合物代谢。48小时后，碳水化合物的有氧氧化减弱，但由于静脉血的存在，在静脉皮瓣中仍保持在相当水平。术后72小时，静脉皮瓣中碳水化合物的有氧氧化达到最低点。此时，除非获得新的营养来源，否则静脉皮瓣将逐渐坏死。从术后第4天起，静脉皮瓣中碳水化合物的有氧氧化开始增加。到第7天，静脉皮瓣中碳水化合物的有氧氧化恢复正常。
