ABSTRACT

An aqueous suspension of clove, Eugenia caryophyllata (Spreng.) (Myrtaceae) was tested for its ability to inhibit basal gastric secretion and to protect gastric mucosa against the injuries caused by pyloric ligation, indomethacin and cytodestructive agents (80% ethanol, 0.2 M NaOH and 25% NaCl) in rats. The suspension in doses of 250 and 500 mg/kg body weight had a significant antiulcerogenic activity on the models used. Besides, ethanol-induced depleted non-protein sulfhydryl (NP-SH) and gastric wall mucus contents were replenished by pretreatment with clove suspension. No significant histopathological changes are noted. In acute, chronic and genotoxicity tests clove suspension showed a large margin of safety in the animals and did not induce any significant changes in the micronucleated polychromatic erythrocytes (PCE) and the ratio of PCE and normochromatic erythrocytes (NCE) at both doses used, as compared to control group, suggesting lack of any significant clastogenic and/or cytotoxic potentials.
