METHODS: Colitis was induced in male Sprague-Dawley rats via intrarectal instillation of TNBS. Then, the rats were treated with piperine (10, 20, and 40 mg/kg, p.o.) for 14 days.
RESULTS: TNBS induced significant (0.05) colonic damage, which was assessed by disease activity index, macroscopic score, and stool consistency.这些损害的侵蚀剂(20和40 mg/kg)的给药显着抑制(0.05)。用哌氨致(20和40 mg/kg)处理的治疗显着抑制(0.05)TNBS诱导的氧化硝化胁迫升高(超氧化物歧化酶,谷胱甘肽,丙硫代,丙二醛和氮氧化物和氮氧化物),5-羟基甲状腺素和氢氧化胺的含量为5-羟基丙氨酸和氢氧化胺的含量。此外,结肠诱导的一氮OXIDE合酶(INOS),肿瘤坏死因子-Alpha(TNF-α),介体(IL)-1β,IL-6,IL-6,干扰素 - γ和环氧酶-2(COX-2)Messenger RNA(mRNA)的稳定性(MRNA)表达在TNBS启动和piperiLlation and Piperine and Piperine(20和40mg/kg)的表达中(20和40 mg/k)表达。 TNB降低了紧密连接(TJ)蛋白(Claudin-1,occludin和Zonula occludens-1(ZO-1))的表达,并增加了促凋亡(caspase-1)蛋白的表达。这些表达式通过胡须治疗明显抑制(0.05)。 Histological and ultrastructural studies of transmission electron microscopy suggested that piperine significantly ameliorated (0.05) TNBS-induced colonic aberrations.
CONCLUSION: Piperine ameliorated the progression of TNBS-induced colitis by modulating the nuclear factor of kappa light polypeptide gene B细胞抑制剂-Alpha/核因子-kappa B信号通路中的增强子,从而抑制促炎细胞因子(TNF-α和ILS),COX-2,INOS,氧化硝基抗应激和促凋亡蛋白(caspase-1)的过度表达,这些蛋白(caspase-1)可能会改善TJ蛋白(claudin-1,coctin-1,coccludin和ZO-1)的表达
