目的 :探索中药黄芩对放射损伤所致组织态学变化的影响。方法 :照前 30min左右给健康家兔腹腔注射 2 g/kg黄芩水提取液 ,于受照射后 6个月用光学显微镜及透射电镜观察兔眼晶状体及胃粘膜的组织形态学变化。结果 :黄芩组兔眼晶状体及胃粘膜的组织形态学改变明显轻于受照射组。结论 :中药黄芩可减轻放射损伤所致组织形态学变化
Objective: To explore the effect of Radix Astragali on the histopathological changes caused by radiation injury. METHODS: Healthy rabbits were injected intraperitoneally with 2 g/kg Astragalus membranaceus extract for 30 min before irradiation. Six months after irradiation, the histomorphological changes of lens and gastric mucosa were observed by light microscope and transmission electron microscope. RESULTS: The histomorphological changes of the lens and gastric mucosa of rabbits in the Astragalus group were significantly lighter than those in the irradiated group. Conclusion : Astragalus membranaceus can reduce the histomorphological changes caused by radiation injury
