Abstract:
Objective To study the effects of Liang-Xue-Yu-Chang decoction on intestinal epithelium of rats with radiation enteritis.Methods Sixty male SD rats were divided into three groups randomly:normal rats as control,abdominal radiation control group given distilled water after 10 Gy radiation,and abdominal radiation plus drug group given Liang-Xue-Yu-Chang decoction after 10 Gy radiation.Drugs or distilled water were chronically administered to animals for 7 days.After that,5-bromodexyridine (BrdU) was injected into abdominal cavity,SP immunohistochemistry was used to evaluate intestinal epithelium proliferating cell nuclear antigen (PCNA) and the positive cells labeled with Ki67 and BrdU.Results The number of intestinal epithelium cells with PCNA expression,positive Ki67 and BrdU were 22.0 + 2.7,71.2 + 5.7,and 26.2 + 5.9 respectively in the drug treatment group,significantly higher than those in the abdominal radiation control group (11.2 + 1.9,61.6 ± 5.5,and 11.3 ± 2.2) (t =14.629,5.420,11.582,P ＜ 0.05),but lower than those in the normal control group (30.4±5.7,86.6 ±5.1,and 32.3 ±3.2)(t =14.291,9.004,4.731,P＜0.05).Conclusion Liang-Xue-Yu-Chang decoction could improve the proliferation of intestinal epithelium in the rats with radiation enteritis.
