The copper in stick lac existed mainly in the corpses of the lac insect and that was the main pollution source causing copper pollution in laccaic acid ( lac dye). 紫胶原胶中的铜高度富集于紫胶虫尸体之中,它是引起紫胶红色素铜污染的主要污染源。
AIM: To measure the difference in glucose and lactate levels between brain extracellular fluid ( ECF) and plasma of rabbits and analyzed the effects of lactic acid on central nervous system. 目的:观察兔脑细胞外液与血液中葡萄糖(Glu)及乳酸(Lac)的差异,分析乳酸在中枢神经系统中的作用。
Investigating the property of hydrolysate of domestic lac resin, and based on the property differences between the salts of long chain aliphatic and terpene acids, aleuritic acid and shellolic acid were isolated. 研究了国产紫胶树脂水解物的性质,利用长链脂肪酸及环状萜烯酸某些盐类性质的差异,分离得到了紫胶桐酸和壳脑酸。
Study on bleaching mechanism of chain component in LAC resin-aleuritic acid 紫胶树脂链状组分紫胶桐酸漂白机理的研究
Microdialysis ( MD) was applied to monitor the levels of glucose ( Glu), lactic acid ( Lac), pyruvic acid ( Pyr) in the cerebral extracellular fluid ( ECF) in each group, and calculated the ratio of Lac and Pyr. 应用微透析仪监测各组大鼠脑组织间液中葡萄糖(Glu)、乳酸(Lac)及丙酮酸(Pyr)含量,并计算乳酸/丙酮酸比值;
