摘要
目的:探讨竹荪多糖对砷中毒大鼠体内砷含量的影响。方法:将24只清洁级健康SD大鼠均分为对照组、模型组、竹荪干预组3组,每组雌雄各半;对照组以常规饲料饲养,竹荪干预组和模型组喂饲砷含量50 mg/kg的饲料,竹荪干预组每日以10 g/L的竹荪多糖按大鼠体质量20 m L/kg灌胃,观察各组大鼠喂养过程中的毛发光泽度等一般情况,记录喂养0、30、60及90 d时大鼠的体质量;喂养3月时,取各组大鼠血液及尿液、并处死大鼠取肝脏组织,采用原子荧光光谱法检测其中砷含量,同时称取各组大鼠肝脏重量并计算脏器系数。结果:对照组大鼠发育正常,精神良好,毛发有光泽,模型组大鼠生长中等,体态中等,毛发较暗淡且稀疏,竹荪干预组大鼠发育、精神及毛发光泽度介于两组之间;与对照组相比,饲喂相同的时间,模型组和竹荪干预组体质量均降低,在饲喂30 d、90 d时差异有统计学意义(P<0.05);开始饲喂后,竹荪干预组大鼠体质量与模型组相比升高,但仅30 d时差异有统计学意义(P<0.05);与对照组相比,模型组和竹荪干预组脏器重量和脏器系数、肝砷、血砷、尿砷均升高(P<0.05);与模型组相比,竹荪干预组与模型组相比,竹荪干预组肝砷降低而尿砷升高(P<0.05)。结论:竹荪多糖可以降低砷中毒大鼠肝脏、血液、尿液中的砷含量。
Objective：To investigate the effect of dictyophora polysaccharide on arsenic content in arsenic poisoning rats. Methods：A total of 24 healthy adult clean SD rats were randomly divided into control group,dictyophora polysaccharide intervention group and model group,half male and half fe-male in each group. The control received ordinary feed. Dictyophora polysaccharide intervention group and the model group received feed of 50 mg/kg arsenic content. Meanwhile,dictyophora polysaccha-ride intervention group received intragastric administration of dictyophora polysaccharide（ 10 g/L ）at 20 mL/kg every day. The rats′hair gloss and other general conditions in the feeding process were ob-served and the rats′body weight at 0,30,60 and 90 d after feeding were recorded. 3 months after feeding and treatment,the blood and urine of rats in each group were taken,and the rats were sacri-ficed to get the liver tissue. The content of arsenic was detected by atomic fluorescence spectrometry in rats′blood,urine and liver tissue,and the liver weight of rats in each group was calculated and the or-gan coefficient was calculated. Results：The rats in the control group developed normally,the spirit was good,and the hair was glossy while the rats in model group developed relatively medium,and the hair was dark and sparse. In dictyophora polysaccharide intervention group,the rats′development, spirit and hair gloss were between control group and model group. Compared with control group,at the same time of development,the body weight of rats in model group and dictyophora polysaccharide in-tervention group decreased,and the differences at 30 d,90 d after feeding were statistically significant （P〈0. 05）. After feeding,in dictyophora polysaccharide intervention group rats′body weight in-creased compared with that of model group,but there was significant difference at 30 d after feeding （P〈0. 05）. Compared with control group,in model group and dictyophora polysaccharide interven-tion group the liver weight,organ c
