**Protective Effect of Zanthoxylum nitidum Bark in Chemical and Stress Induced Gastric Mucosal Lesions in Male Albino Rats**

Zanthoxylum nitidum (Roxb.) DC (Rutaceae), called Tez-mui or Tejamool in Assamese, is a large prickly shrub occurring in North-Eastern India and its roots are used traditionally for several medicinal purposes. In the present study, the aqueous extract from the stem bark of Zanthoxylum nitidum (ZNA) was evaluated for its protective effects on gastric mucosal lesions in male Wistar albino rats against acetylsalicylic acid (ASA), ethanol and water immersion restraint stress induced gastric mucosal damage. In each model, ZNA was administered orally to rats at the doses of 100 and 200 mg kg^-1 body weight, prior to chemical or stress challenge, followed by determination of ulcer index. Ranitidine hydrochloride at the dose of 35 mg kg^-1, p.o. served as the reference drug. The test extract exhibited dose dependent and significant amelioration of gastric mucosal lesions in chemical (ASA and ethanol) as well as in stress-induced ulcers in male Wistar albino rats, thus confirming its antiulcer potential.
