“The root of ginseng (Panax ginseng Meyer) has been traditionally used for medicine and food. The primary physiologically-active substances of ginseng are ginsenosides, polyacetylenes, ginseng proteins, polysaccharides, and phenolic compounds. Ginsenosides in particular have been identified as the principal component of ginseng, displaying various biochemical and pharmacological properties. A number of researchers have studied the components of ginseng since the late 1960s, starting with the research of Shibata JQ1 research buy et al [1], whose research group identified the chemical structures of ginsenosides. Ginsenoside Re (C53H90O22) is the main ingredient of ginseng berries and roots. Notably, the amount of ginsenoside Re in the berries was four to six times more than that in the roots [2]. Research in the area has shown that ginsenoside Re exhibits multiple pharmacological activities via different mechanisms both in vivo and in vitro [3], [4], [5], [6], [7] and [8]. However, the pharmacological effects of ginsenoside Re on gastritis or gastric ulcer have not yet been studied. A gastric Compound C supplier ulcer is one of the most common diseases in the world, which

affects approximately 5–10% of people during their lives. The therapy used to treat gastric ulcers includes control of acid secretion as well as the inflammation reversal to the mucosa. Korea red ginseng can assist in the eradication of Helicobacter pylori and alleviate H. pylori-induced halitosis [9]. A recent pharmacological investigation reports the antihistamine why and anticytokine releasing effects of ginsenoside Re isolated from the berries of Panax ginseng [7]. For the common treatment of mild gastritis, antacids in liquid or tablet form are typically used. When antacids do not provide sufficient

relief, H2 blocking medications, such as cimetidine, ranitidine, nizatidine, and famotidine, which help reduce the amount of acid are often prescribed [10]. Famotidine, the most potent H2 receptor antagonist, was used as a positive control [11]. The present study examined the protective effect of ginsenoside Re on acute gastric mucosal lesion progression in rats treated with compound 48/80 (C48/80). C48/80 causes degranulation of mast cells in connective tissue with the release of histamine from the cells, and causes the development of acute gastric mucosal lesions with neutrophils infiltrating into the gastric mucosal tissue [12] and [13]. Injecting C48/80 is consequently suggested as a good model for elucidating the mechanisms of clinical acute gastric lesions [14]. Ginsenoside Re was prepared according to a previously reported method [7]. In brief, dried ginseng berries (5 kg) were ground to powder and extracted twice with 1 L of 95% ethyl alcohol for 2 h in a water bath (60°C). The extracts were concentrated by a vacuum evaporator (Eyela Co.
