Anti-oxidant and anti-inflamatuar effectiveness of caftaric acid on gastric ulcer induced by indomethacin in rats.

In this study, we evaluated the anti-oxidant and anti-inflammatory effect of caftaric acid against ulcer produced by indomethacin in gastric mucosa. Female Sprague Dawley albino rats were divided into five groups: control (saline group, n = 8), negative control (indomethacin group, n = 8), positive control (omeprazole group, n = 8), low dose therapy (caftaric acid, n = 8), and high dose therapy (caftaric acid, n = 8). At the end of the experiment, all rats were sacrificed and gastric mucosa samples were removed for macroscopic and biochemical analysis. In our study, we detected that oxidant parameter values and cytokine levels increased in the negative control group, but total antioxidant status reduced, whereas, cytokine and oxidant parameter levels were significantly reduced due to low and high doses of caftaric acid administration. But another important point to note is that high dose caftaric acid therapy performed gastroprotective effect as omeprazole. In the macroscopic evaluation, there were reductions in ulcer sizes with a low and high dose of caftaric acid administration in contrast to the negative control group. As a result of our study, caftaric acid showed anti-oxidant and anti-inflammatory effects in indomethacin-induced gastric ulcer in rats.
