Protective Effect of Methanolic Extract of Tamarindus Indica Leaves in Ethanol-Induced Esophageal Ulcer in Adult Wistar Rats
Abstract:Tamarind (Tamarindus indica L.) possess anti-ulceration, wound healing, anti-inflammatory and antipyretic properties. This makes it useful in the treatment of various clinical challenges including gastrointestinal tract diseases. The aim of this study was to determine the protective effect of methanolic extract of Tamarindus indica leaves on esophageal ulcers in adult Wistar rats. Twelve rats (12) with average body weights of 130 ± 20 grams (g) were divided into four groups (A, B, C and D) (n=4). Group A (control) received 0.5 ml/kg body weight (bw) of distilled water, Group B received 0.5 ml/kg bw of 80% ethanol, Group C (Low dose) received 200 mg/kg of methanolic extract of Tamarindus indica leaves + 0.5ml/kg of 80% Ethanol and Group D (High dose) received 300 mg/kg of methanolic extract of Tamarindus indica leaves + 0.5ml/kg of 80% Ethanol. All administrations were done via gastric intubation for 6 days. At the end of the experimental period sections of the esophagus were collected for histological studies. The group administered 0.5ml/kg of 80% ethanol when compared with the control group, showed ulceration along the surface margin of mucosal layers and damage to submucosal glands. The group administered high and low doses of methanolic extract of Tamarindus indica leaves + 0.5ml/kg of 80% ethanol when compared with the control group, revealed an intact histoarchitecture. METL was protective in the ethanol induced esophageal ulceration.
