Abstract

An ameliorating effect of Ocimum sanctum on the toxic effect of meloxicam, a new non-steroidal anti-inflammatory drug was studied by evaluating haemato-biochemical parameters, oxidative stress, gross and histopathological changes in various organs of Wistar rats. A total of thirty-six male rats were divided in six experimental groups each comprising of six rats and numbered from G(1) to G(6). Meloxicam toxicity was induced by oral feeding of meloxicam at 1.2 mg/kg and 2.4 mg/kg body weight in G(2) and G(3) respectively for 28 days. Group G(4) and G(5) were fed with 1.2-mg/kg body weight and 2.4-mg/kg body weight of meloxicam along with 200 mg/kg body weight of aqueous extract of Ocimum sanctum. Group G(1) serve as control while group G(6) was kept as treatment control and fed only aqueous extract of Ocimum sanctum at 200 mg/kg body weight. Clinical finding showed mild diarrhea from 23(rd) day onwards in-group treated with 2.4-mg/kg body of meloxicam. Significant reduction of hemoglobin and packed cell volume (PCV) was observed in both the group treated with 1.2 mg/kg and 2.4-mg/kg body wt. of meloxicam. Ocimum sanctum could restore the hemoglobin and PCV value in-group treated with meloxicam at low dose level. Serum alkaline phosphatase, serum glutamic pyruvic transaminase, Serum glutamic oxaloacetic transaminase and total bilirubin were found elevated in meloxicam treated groups and indicated hepatotoxic activity of meloxicam. Ocimum sanctum could reduce hepatotoxic activity of meloxicam in group G4 receiving meloxicam at lower dose rate along with Ocimum sanctum failed to regulate creatinine level in meloxicam treated groups. In meloxicam toxicity elevated Lipid peroxidation values was noticed in liver and kidneys, while superoxide dismutase and glutathione did not revealed any change. Stomach and intestine revealed hemorrhagic gastroenteritis and ulcers. Perivascular necrosis with infiltration with inflammatory cells was evident in liver. Interstitial nephritis, myocardial necrosis and spongiform encephalopathy were important lesions. The Ocimum sanctum could only counteract the toxic effect of meloxicam in liver and gastrointestinal tract.
