Blotting of cPLA2, COX-1, and COX-2 The considerably improved expression of cPLA2 (0.82) within the rat stomachs 1 hour right after administration of ethanol (Fig. 3A) was lowered by PMK-S005 pretreatment to 0.27 (5 mg/kg, p=0.002) or 0.41 (ten mg/kg, p=0.014). Related to cPLA2, the improved COX-1 (Fig. 3B) and COX-2 expression (Fig. 3C) was also considerably suppressed by pretreatment with 5 mg/kg or 10 mg/kg of PMK-S005. Rebamipide pretreatment also significantly decreased the ethanol-induced cPLA2, COX-1, and COX-2 expressions. 5. Impact of PMK-S005 on PGE2 and LTB4 level in ethanolinduced gastric damage Considering that our Western blot results indicated that pretreatment with PMK-S005 suppressed the ethanol-induced cPLA2, COX-1 and COX-2 expression, we examined further downstream elements of inflammatory responses. The mucosal amount of PGE2 was not considerably changed following ethanol administration, and oraladministration of PMK-S005 didn’t impact the mucosal PGE2 level (Fig. 3D). In contrast to PGE2, the enhanced mucosal degree of LTB4 immediately after ethanol administration was decreased by pretreatment with PMK-S005 at a concentration of five and ten mg/kg (p0.L-Homocysteine Metabolic Enzyme/Protease 001) and rebamipide (Fig. 3E). six. Effect of PMK-S005 on gastric HO-1, NQO-1, GCLC, and GCLM expression In the next, we determined no matter if PMK-S005 could potentiate the antioxidative capacity of gastric mucosa. Rats fed with PMK-S005 (5 or ten mg/kg) for 14 days showed no histological adjust in gastric tissue (information not shown). The protein levels of HO-1, NQO-1, GCLC, and GCLM had been drastically enhanced in the rat stomachs in PMK-S005-treated rats compared together with the manage rats (Fig. four).DISCUSSIONA variety of plant-derived flavonoids and their derivates happen to be demonstrated to have the gastroprotective effects.19-21 Garlic (Allium sativum ) has long been made use of as a typical dietaryRebK1 am 0 ip id eKKKKK1 PMtrotroKKOOtroPMPMPMPMipOPMPMPMonononEtEtEtamPMKHHidHlllGut and Liver, Vol. ten, No. three, MayA1.0 0.B2.C2.COX-1/b-Actin0.6 0.4 0.2* * *1.5 1.0 0.5COX-2/b-Actin2.cPLA2/b-Actin1.five 1.0 0.* * ** **l Et O H PM K1 PM K5 PM K1 R eb am 0 ip id el Et O H PM K1 PM K5 PM K1 R eb am 0 ip id ecPLA2 b-ActinCOX-1 b-ActinCOX-2 b-ActinDE200 150 100 50 0PGE2 (pg/mg)LTB4 (pg/mg)*am 0 ip id eCebCRFig. three.
