本文研究了膳食中锌缺乏对大鼠红细胞膜骨架蛋白组成和结构的影响。实验用刚断奶的雄性Wistar大鼠(44～58 g),于22℃,光周期700～1900 h中单笼饲养,自由摄取重蒸去离子水(<0.01 mg Zn/L)和蛋清基础饲料(<1.0 mg Zn/kg),饲养3周。随机分为以下实验组(1)锌缺乏组(—Zn),自由进食锌含量<1.0 mg/kg的饲料,(2)补锌组(—ZnRF),实验前18 d自由进食锌含量<1.0 mg/kg的饲料,后3 d进食含锌100 mg/kg的基础饲料,(3)成对饲养组(+ZnPF),进食加锌100 mg/kg的基础饲料,(4)自由进食组(+ZnAL),自
This article studies the effects of dietary zinc deficiency on the composition and structure of rat erythrocyte membrane scaffold proteins. The experimental weanling male Wistar rats (44-58 g) were housed in a single cage at 22 ℃ for 700 ~ 1900 h in photoperiod and were fed freely with distilled water (<0.01 mg Zn / L) and basal diet of egg white (<1.0 mg Zn / kg) for 3 weeks. The rats were randomly divided into the following experimental groups: (1) zinc deficient group (-Zn), free diet of zinc content <1.0 mg / kg, (2) zinc supplementation group (3) Paired feeding group (+ ZnPF), fed basic diet supplemented with 100 mg / kg of zinc, (4) Free feeding group + ZnAL), since
