- W4301606427 abstract "Background: Vernonia amygdalina del. (Arecaceae) leaf, popularly known as ‘Bitter leaf’ is widely used as a leafy vegetable in soups and in folkloric medicine against many ailments including stomach discomfort.
 Aim: The current study aimed to assess the gastroprotective effect of the crude aqueous extract of V. amygdalina leaves (AEVAL) on Hydrochloric acid (HCl)/Ethanol gastric ulcer models.
 Study Design: An animal experimental study which was conducted for 14 days.
 Place and Duration of Study: Department of Medical Laboratory Sciences, and Animal House, College of Medicine, University of Nigeria, Enugu Campus, between May 2013 and August 2014.
 Methodology: Preliminary acute toxicity testing was performed. Twenty (25) rats were divided into five groups (n=5). Groups I and II were normal and ulcer control groups respectively. Groups III, IV and V were pretreated with cimetidine (100 mg/kg), 250 mg/kg AEVAL and 500 mg/kg AEVAL respectively. Cimetidine and AEVAL were administered intraperitoneally and orally, respectively, once daily for 7days. After drug treatments on Day 7, gastric ulcers were induced using HCl/ethanol solution (1ml/rat) prior to sacrifice. Ulcer indices and percentage ulcer inhibition were determined. The stomach tissues were excised, histologically processed and evaluated for histopathological alteration under light microscopy.
 Results: Acute toxicity testing revealed that AEVAL at a dose of 5000 mg/kg body weight did not cause any mortality. Macroscopical evaluation of the gastric mucosa revealed severe lesions following induction with HCl/ethanol. However, profound protective effects were observed with cimetidine and AEVAL (250 and 500 mg/kg) pretreatments with ulcer inhibition of 79%, 58% and 76% respectively. Histopathological findings were consistent with the macroscopical features observed.
 Conclusion: Data from this study suggest that oral treatment with V. amygdalina leaves extract exhibited gastroprotective activities against the injurious effects of acidified ethanol on the gastric mucosa of albino rats." @default.
