Abstract:CONTEXT: Rutin, a flavonoid commonly present in onions, apples and tea, has been suggested to have a variety of pharmacological activities, including immunomodulator, anti-inflammatory and抗氧化活动。
目标: 本研究是检查保护效果of rutin on gastric mucosal damage induced by gastric ischemia-reperfusion (I/R) in rats.
MATERIALS AND METHODS: Rutin (50, 100, 200 mg/kg) was administered intragastrically for five consecutive days before ischemia.在最后一次给药鲁丁蛋白的六十分钟后,在麻醉下,将腹腔动脉夹住30分钟,然后将夹子切除60分钟。再灌注后,将胃去除以进行生化和组织学检查。
结果: 与I/R组相比(116.7±21.5),在50,100和200 mg/kg的剂量上施用rutectin(116.7±21.5)胃I/R(分别为73.4±14.8、65.9±9.6和26.9±5.7)。 ED50值为138.7 mg/kg。此外,rutin的剂量为50、100和200 mg/kg,表现出对增加的脊髓过氧化物酶的抑制作用(24.6,41.3 aND降低53.1%)活性和丙二醛水平(27.4、40.3和50.7%)的胃粘膜。 Also, the elevation of inducible NO synthase (iNOS) activity as well as the decrease of constitutive NO synthase (cNOS) in the gastric mucosa were significantly prevented by rutin pretreatment.
CONCLUSION: These results suggested that rutin has a protective effect against gastric mucosal injury由胃I/R诱导,胃保护与NOS/NO途径及其抗氧化活性有关。
