摘要：

In this study we have investigated the relative influence of capsaicin-sensitive afferents and sialoadenectomy on gastric acid secretion. Sialoadenectomized (SALX) rats showed a decrease in gastric acid secretion and an increase in gastric calcitonin gene-related peptide-like immunoreactivity (CGRP-li) as compared to sham-operated animals. Capsaicin pretreatment (50+100 mg kg-1 in two days) markedly decreased gastric CGRP-li in both sham and SALX-operated rats and increased acid concentration and output only in SALX animals. In this latter case the concomitant absence of two potent endogenous antisecretory agents (CGRP and epidermal growth factor; EGF) may contribute to the observed hypersecretion. Gastric content of vasoactive intestinal polypeptide (VIP)-li was unaffected in SALX and capsaicin-treated rats. Capsaicin-sensitive afferents and EGF contained in the salivary glands may interact in the regulation of the gastric acid secretion.
