摘要: 探讨牦牛皮胶对环磷酰胺所致的贫血小鼠的血象红系参数和脾脏结构的影响。采用腹腔注射环磷酰胺建立小鼠贫血模型,造模4天后各给药组小鼠分别ig牦牛皮胶1、2、3、6 g/ (kg·d),阿胶补血颗粒14.05 g/ (kg·d),在给药后的第7、14、21天检测各组小鼠的外周血象,计算脾脏和胸腺系数,切片观察脾脏的形态结构。结果表明,与模型组相比,1 g/(kg·d)牦牛皮胶给药组给药7、14、21 d,血红蛋白显著升高(P<0.05);2 g/(kg·d)牦牛皮胶给药组给药7、14、21天,红细胞数、血红蛋白、红细胞比容、平均血红蛋白量及平均血红蛋白浓度显著升高(P<0.05);3 g/(kg·d)牦牛皮胶给药组给药14、21天,红细胞数及平均血红蛋白浓度显著升高(P<0.05);6 g/(kg·d)牦牛皮胶给药组给药7、14天,平均血红蛋白量显著升高(P<0.05);各给药组脾脏淋巴细胞增多,白髓与红髓的界限变清晰。综上,各浓度牦牛皮胶对贫血小鼠均有补血作用,其中2 g/(kg·d)的牦牛皮胶给药剂量,14天的给药时间的补血作用较为理想。

Abstract: To investigate the effects of yak skin gelatin on erythroid parameters and spleen structure of cyclophosphamide-induced anemia mice.Intraperitoneal injection cyclophosphamide for 4 days to establish the aplastic anemia mice model,then divided the anemia mice into 6 groups.Besides the model group,the other 5 groups were received yak skin gelatin,1 g/(kg·d),2 g/(kg·d),3 g/(kg·d) and 6 g/(kg·d)) and Lvjiaobuxue granules(14.05 g/(kg·d) respectively.After 7,14 and 21 days’ administration,singled out mice randomly and analyzed the erythroid parameters,organ indexes and morphology of the spleen.The results showed that,compared with the model group,HGB was significantly increased (P<0.05) in the 1 g/(kg·d) group on 7th,14th and 21th day.RBC,HGB,HCT,MCH and MCHC were significantly increased (P<0.05) in the 2 g/(kg·d) group on 7th,14th and 21th day.RBC and MCHC were significantly increased (P<0.05) in the 3 g/(kg·d) group,and MCH was significantly increased (P<0.05) in the 6 g/(kg·d) group on 7th and 14th day.Additionally,splenic lymphocytes increased and the line between white pulp and red pulp in the spleen became evident in each medicated group.These indicated that all concentrations of yak skin gelatin had a positive effect on hematopoietic function,and continuous received 14 d at the dose of 2 g/(kg·d) yak skin gelatin could greatly improve anemia.
