目的:探讨黑木耳多糖对高功率微波辐射大鼠卵巢和子宫形态结构的影响。方法:Wistar大鼠30只,随机分为正常对照组、辐射模型组和治疗组,每组10只。辐射模型组和治疗组给予表面功率200 mW/cm2,10 min的微波辐射。正常对照组和辐射模型组蒸馏水1.5 ml灌胃,治疗组1%木耳多糖1.5 ml灌胃,连续10天。第11天取卵巢和子宫,制备组织学标本,光学显微镜观察。结果:治疗组与辐射模型组相比,卵巢皮质增厚,卵泡数量增多,各级卵泡形态结构基本正常,黄体形态规则;子宫内膜增厚,上皮细胞排列较紧密,固有层内子宫腺增多,腺腔扩大,组织细胞结构基本正常。结论:木耳多糖在高功率微波辐射时,对卵巢和子宫具有保护修复作用。
Objective: To investigate the effect of black fungus polysaccharide on morphology of ovary and uterus in rats exposed to high power microwave radiation. Methods: Thirty Wistar rats were randomly divided into normal control group, radiation model group and treatment group, with 10 rats in each group. Radiation model group and treatment group were given microwave power with a surface power of 200 mW / cm2 for 10 min. Normal control group and radiation model group 1.5 ml distilled water gavage, the treatment group 1% fungus polysaccharides 1.5 ml gavage for 10 consecutive days. Ovary and uterus were taken on the 11th day, histological specimens were prepared and observed under light microscope. Results: Compared with the model group, the ovarian cortex was thickened and the number of follicles was increased in the treatment group. The follicle morphology at all levels was basically normal and the morphology of the corpus luteum was regular. The thickness of the endometrium was thicker, the epithelial cells were arranged more closely, , Enlarged glandular cavity, the basic normal cell structure. Conclusion: Edible fungus polysaccharide can protect and repair the ovary and uterus under high power microwave radiation.
