The lyophilized decoction of Salvadora persica L. roots possesses a significant protective effect on ulceration induced by ethanol, indomethacin and cold restraint stress in rats. In this work, we study the effect of chronic intragastric administration of S. persica decoction on experimental acetylsalicylic acid (ASA)-induced ulcer in rats. The ulcer index significantly decreased (U.I. 0.9 +/- 1.6; P < 0.05) after treatment with a lyophilized decoction of S. persica (500 mg/kg, os), once daily for seven days, with respect to controls (U.I. 11.4 +/- 2.3). The modification of gastric mucosa was observed by transmission electronic microscopy (TEM) confirming this result. In fact, in treated rats, the mucosa recovered to normal distribution. After S. persica treatment, some changes were detected in profiles of various cytoplasm organelles of parietal cells. Particularly, the intracellular canaliculi show an enlarged lumen with an increase in the number and length of microvilli. These morphological features of parietal cells after S. persica treatment suggest that the cells tend to recover a moderate secretory activity, even if the drug still discloses its inhibitory effect. Moreover, S. persica decoction possesses significant antiinflammatory activity.

Abstract

The lyophilized decoction of Salvadora persica L. roots possesses a significant protective effect on ulceration induced by ethanol, indomethacin and cold restraint stress in rats. In this work, we study the effect of chronic intragastric administration of S. persica decoction on experimental acetylsalicylic acid (ASA)-induced ulcer in rats. The ulcer index significantly decreased (U.I. 0.9 +/- 1.6; P < 0.05) after treatment with a lyophilized decoction of S. persica (500 mg/kg, os), once daily for seven days, with respect to controls (U.I. 11.4 +/- 2.3). The modification of gastric mucosa was observed by transmission electronic microscopy (TEM) confirming this result. In fact, in treated rats, the mucosa recovered to normal distribution. After S. persica treatment, some changes were detected in profiles of various cytoplasm organelles of parietal cells. Particularly, the intracellular canaliculi show an enlarged lumen with an increase in the number and length of microvilli. These morphological features of parietal cells after S. persica treatment suggest that the cells tend to recover a moderate secretory activity, even if the drug still discloses its inhibitory effect. Moreover, S. persica decoction possesses significant antiinflammatory activity.
