Abstract

To examine the effects of basic fibroblast growth factor (bFGF) on gastric secretion, the present study was carried out using pylorus-ligated rats. Intracisternally injected bFGF inhibited the secretion of both gastric acid and pepsin, and this gastric antisecretory action of bFGF was a dose-related response. On the other hand, the intraperitoneal injection of bFGF did not change gastric secretion. These results strongly suggested for the first time that bFGF, a growth factor that promotes the proliferation of various cell types, might also be a chemical messenger that is involved in the central regulation of gastric secretion. This biological action of bFGF may be considered as a novel nonmitogenic activity of this growth factor.

    Recent reports showed that the β-glucan isolated from highland barley and fermented barley bran extracts can effectively prevent gastric mucosal damage induced by ethanol-administration in mice by decreasing the inflammatory response, alleviating the gastric oxidative stress injury in the vehicle rats and decreasing the level of malondialdehyde [35,36]. In this study, results revealed that the macromolecular β-glucan H6PC20 had protective effect on ethanol injured gastric mucosa with the mechanism of decreasing the inflammatory response and alleviating the oxidative injury, more importantly improving the secretion of defense and repair factors like EGF, bFGF and PGE2 in gastric mucosa, further activating the body defense and repair system [37–39]. HPB-3 was a kind of heteropolysaccharide with a molecular weight of 15 kDa containing α-(1/6)-linked galactopyranosyl backbone, partially with a side chain composed of α-l-fucopyranose at the O-2 position [16].

    Serum gastrin concentrations were measured by a radioimmunoassay kit (Gastrin RIA Kit II; Dainabot Co. Ltd, Tokyo, Japan). In 5 rats from each group, the gastric acid secretion during WRS was measured by a pylorus ligation method, as reported previously.44 Seven-week-old male Wistar rats were used for the experiments.
