Protective Effect of Crocin on Gastric Mucosal Lesions Induced by Ischemia-Reperfusion Injury in Rats
نویسندگان
چکیده مقاله:
The present study aimed to evaluate the protective effect of crocin on gastric mucosal lesions caused by ischemia-reperfusion (I/R) injury in rats.Forty male rats were randomly divided into sham, control (I/R injury) and three crocin-pretreated groups. To induce I/R lesions, the celiac artery was clamped for 30 min and then the clamp was removed to allow reperfusion for 3 h. Pretreated-rats received crocin (7.5, 15 or 30 mg/kg, i.p.) 30 min prior to the induction of I/R injury. Samples of gastric mucosa were collected to measure the following variables: 1. mRNA expression of superoxide dismutase (SOD) and glutathione peroxidase (Gpx) by RT-PCR; 2.activity of superoxide dismutase and glutathione peroxidase and 3.tissue levels of malonyldehaldehyde (MDA).Pretreatment with crocin decreased the total area of gastric lesions. Messenger RNA expressions of SOD and Gpx in control I/R injury rats were significantly decreased as compared with sham-operated group (P

متن کاملProtective effect of quercetin on ischemia/reperfusion-induced gastric mucosal injury in rats.
This study was designed to determine the gastroprotective properties of quercetin in ischemia/reperfusion-induced gastric mucosal injury and the involvement of endogenous prostaglandins in this process. Oral pretreatment of rats with quercetin (100 mg x kg(-1)) 30 min before surgery significantly decreased the length of gastric mucosal lesions. However, lower doses of quercetin (25 and 50 mg x ...

Background:Troxerutin has antioxidant and anti-inflammatory properties and in this study, its antioxidant effect on the reduction of oxidative stress induced by ischemia-reperfusion sciatic nerve injury was investigated. Methods:In this study, 64 male rats were randomly divided into 8 groups as follows: 1- IR2: ischemia (3 hours) and reperfusion (2 days), 2- T...

Objective(s): This study investigated the protective effect of tanshinone IIA sodium sulfonate (TSS) on ischemia-reperfusion (I/R) induced cardiac injury, and the underlying mechanism of action. Materials and Methods:Male Sprague-Dawley rats were subjected to a 30-min coronary arterial occlusion followed by 24 hours' reperfusion. Half an hour before the left coronary artery ligation, rats were ...
