Reactive oxygen species, neutrophil infiltration and proinflammatory cytokines play an important role in the pathogenesis of gastric ulcers caused by aspirin. The present study demonstrates the healing effect of Cissus quadrangularis extract (CQE) through inhibitory action on generation of lipid peroxidation, proinflammatory cytokines and neutrophil infiltration. The concentration ofmalondialdehye (MDA), protein carbonyl content, conjugated dienes, mucosal (SH) sulphydryls, uric acid, tumor necrosis factor-alpha (TNF-alpha), and activities of myeloperoxidase (MPO), xanthine oxidase (XO) and antioxidative enzymes were determined in the gastric mucosa. Administration of CQE significantly attenuated the gastric lesions induced by aspirin and this was accompanied by the rise in uric acid, antioxidative enzymes, SH groups, and a significant decrease in lipid peroxidase, TNF-alpha, MPO and XO activities. These findings suggest that the significant gastroprotective activity could be mediated by the antioxidant activity as well as by the attenuation of oxidative mechanism and proinflammatory cytokines.

Cissus quadrangularis is an indigenous plant commonly mentioned in Ayurveda for treatment of gastric ulcers. The ulcer-protective effect of a methanolic extract of C. quadrangularis (CQE) was comparable to that of the reference drug sucralfate. Further, gastric juice and mucosal studies showed that CQE at a dose of 500 mg/kg given for 10 days significantly increased the mucosal defensive factors like mucin secretion, mucosal cell proliferation, glycoproteins, and life span of cells. The present investigation suggests that CQE not only strengthens mucosal resistance against ulcerogens but also promotes healing by inducing cellular proliferation. Thus, CQE has potential usefulness for treatment of peptic ulcer disease.
