Thirty female albino Wistar rats were divided into 6 groups of 5 animals each (n=5); Group 1: normal control, Group 2: ulcer rats received normal saline, Group 3: ulcer rats treated with P. halepensis, Group 4: ulcer rats were treated with zinc, Group 5: ulcer rats were treated with P. halepensis + zinc and Group 6 ulcer rats were treated with Ranitidine for 15 days. Stomach ulcer was induced by a single oral administration of indomethacin (30 mg/kg). Various biochimical, physiologic and histologic parameters were estimated. Obtained results show that the ulcer index, pH and total acidity level were significantly reduced (p<0.05) and Pepsin activity was significantly increased (p< 0.05) in ulcer induced rats pre-treated with extract of P. halepensis, zinc and ranitidine when compared with indomethacin treated rats. The MDA level was significantly decreased and GSH level was increased (p< 0.05) in rats treated with plant extract and zinc. Histopathology of gastric mucosa confirmed the gastro-protection by plant and zinc treatment. The study reveals anti-ulcer and antioxidant properties were observed in bark aqueous extract of P. halepensis groups with a benefic effect of zinc to reduce oxidative stress and gastric ulcer induced in the rat.","PeriodicalId":7171,"journal":{"name":"Acta Scientifica Naturalis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43402195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The different aerial parts of three methanolic extracts, exhibited antioxidant activity in the DPPH free radical (IC50, 0.032, 0.087 and 0.044 mg/ml) respectively. The reducing ability of the extracts showed a dose-dependent trend increasing with increase in the concentrations of the extracts.The antioxidant activity of samples at the concentration of 2 mg/ml was reflected in their ability to inhibit the bleaching of β-carotene. Treated groups with extracts of studied three plants showed decrease in plasma levels of AST, ALT, ALP, and an increase in plasma catalase levels activities, while hepatic MDA decreased and catalase increased as compared to carbon tetrachloride treated groups. In consistency with in vivo and in vitro results, extracts of all three plants ameliorated the carbon tetrachloride extensive damage to liver tissue of treated animals, but, Santolina africana extract was the most efficient.","PeriodicalId":7171,"journal":{"name":"Acta Scientifica Naturalis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46974282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
