摘要: 目的 观察葡萄籽原花青素(GSPE)对复发性结肠炎大鼠血清抗氧化能力及NO 含量的影响, 初步探讨葡萄籽原花青素治疗复发性结肠炎的作用机制。方法 直肠给予雄性Wi star 大鼠80 mg/kg 2, 4, 6-三硝基苯磺酸(TNBS)/50 %乙醇溶液复制结肠炎模型, 在第16 天时, 用30 mg/kg TNBS/50 %乙醇溶液诱导结肠炎复发的模型。大鼠第二次致炎24 h 后, 分别应用GSPE 低、中、高剂量(100 、200 、400 mg/kg)灌胃对其进行治疗, 并以柳氮磺吡啶(SASP, 500 mg/kg)作为阳性对照。连续给药7 d 后处死所有大鼠, 取结肠标本评价结肠湿重指数, 生化法检测血清中髓过氧化物酶(MPO)、超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)和一氧化氮合酶(iNOS)活力及丙二醛(MDA)、谷胱甘肽(GSH)和NO 含量。结果 与模型对照组比较,GSPE 各剂量组大鼠体重下降程度较轻(P<0 .05 或P <0 .01), 结肠湿重指数明显降低(P<0 .05 或P <0 .01);大鼠血清中MPO 和iNOS活力及MDA 和NO 含量均明显降低(P <0 .05或P <0 .01);大鼠血清中SOD 和GSH-Px 活力及GSH 含量明显升高(P <0 .05 或P <0 .01)。结论 GSPE 可能通过提高复发性结肠炎大鼠血清抗氧化能力, 抑制NO 生成, 来减轻复发性结肠炎炎症反应。

Abstract: AIM: To investigate the antio xidation of proanthocy anidins from grape seeds (GSPE)on 2, 4, 6-t rinitrobenzene sulfonic acid (TNBS)twice-induced recurrent ulcerative colitiss (UC)in rats and to probe into its underlying mechanism.METHODS: Recurrent colitis model was established in Wistar male rats by rectal administ ration of 80 mg/kg TNBS dissolved in 50 %ethanol, and then the rats were second instilled with 30 mg/kg TNBS into the colon on the 16th day after the first induction UC.Rats were intragastrically administered different doses of GSPE (100, 200, and 400 mg/kg)per day for 7 days after twice-induction of colitis by TNBS. Sulfasalazine (SASP, 500 mg/kg)was used as a positive control drug.Rats were killed after GSPE treatment 7 days.The colon sample was extracted, and the colon weight/length ratio (mg/cm)was assessed.The activities of, myeloperoxidase (MPO), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), inducible nitricoxide synthase (iNOS), and the contents of malony ldialdehy de (MDA)and glutathione (GSH)and NO in se rum were detected by biochemistry method.RESULTS: Compared with the model group, the rat body w eight was decreased, and the colonic weight/length ratio was reduced in GSPE dosage group(P <0.05 or P <0.01);the activities of MPO and iNOS and the contents of MDA,NO in serum were significantly decreased(P <0.05 or P <0.01);but the activit ies of MPO, iNOS and the contents of MDA, NO were decreased (P <0.05 or P <0.01);the activities of SOD, GSH-Px, the contents of GSH in serum were increased(P <0.05 or P <0.01).CONCLUSION: GSPE can alleviate the inflammatory reactions in colitisthrough inhibiting oxygen free reaction, exerting antioxidation effects and decreasing the production of NO.
