Objective To investigate the therapeutic effect of modified powder and vitamin B12 on the treatment of recurrent oral ulcer in rats and its effect on serum interleukin-6 (IL-6) and tumor necrosis factor alpha(TNF-α).Methods Forty-eight male Sprague-Dawley (SD) rats were randomly divided into normal group (equal distilled water),model group (equal distilled water),positive control group (levamisole 20 mg/kg gavage) and experimental group (containing dcsgd crude drugs 1 g/mL,1.278 mL/200 g+ B12 20 g/kg gavage),each group with 12 rats.Model group,positive control group and experimental group were treated with immunological method to establish the recurrent oral ulcer mode.Each group treated with the corresponding treatment methods for 20 days.Results The oral ulcer number,duration time in positive control group and the experimental group were significantly lower than that in model group rats(P＜0.05),ulcer interval time was significantly longer than the rats in the model group (P＜0.05);the serum IL-6,TNF-α detection level in positive control group and experimental group were significantly lower than in the model group(P＜0.05);serum IL-6,TNF-α detection level in model group were significantly higher than those in normal group(P＜0.05);the peripheral blood SOD,GSHPx levels in positive control group and experimental group rats were significantly higher than that in model group(P＜0.05),the level of MDA was significantly lower than that in model group (P＜0.05).Conclusion Modified powder and vitamin B12 have therapeutic effects on recurrent oral ulcer in rats.The mechanism may be related to reducing the inflammatory reaction and improving the antioxidant capacity of the tissue.%目的 探讨加味导赤散与维生素B12对大鼠复发性口腔溃疡的治疗效果及对血清白细胞介素6(IL-6)、肿瘤坏死因子-α(TNF-α)的影响.方法 选取SPF级雄性SD大鼠48只,采用随机数字表法分为正常组(等量蒸馏水)、模型组(等量蒸馏水)、阳性对照组(左旋咪唑20 mg/kg灌胃治疗)、实验组(使用含有加味导赤散生药材1 g/mL,1.278 mL/200 g+维生素B1220 μg/kg灌胃)各12只,模型组、阳性对照组、实验组采用免疫法建立复发性口腔溃疡模型,建模后按照对应治疗方法处理20 d.结果 阳性对照组、实验组大鼠的口腔溃疡数目、溃疡持续时间均显著低于模型组大鼠(P＜0.05),阳性对照组、实验组大鼠的溃疡间隔出现时间均显著长于模型组大鼠(P＜0.05);阳性对照组、实验组大鼠的血清IL-6、TNF-α检测水平均显著低于模型组大鼠(P＜0.05);模型组的血清IL-6、TNF-α检测水平显著高于正常组(P＜0.05);阳性对照组、实验组大鼠的外周血超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSHPx)水平均显著高于模型组大鼠(P＜0.05),丙二醛(MDA)水平显著低于模型组(P＜0.05).结论 加味导赤散与维生素B12对大鼠复发性口腔溃疡具有治疗作用,作用机制可能与减轻炎性反应、提高组织的抗氧化能力有关.
