The effect of gamma-aminobutyric acid (GABA) on basal and bombesin (BBS)-stimulated release of somatostatin (SLI) and gastrin from isolated perfused rat stomach was examined. In the control study, BBS at a dose of 10 nM significantly stimulated release of SLI and gastrin. Infusion of GABA (1-1000 nM) caused a depression of SLI release induced by BBS (10 nM) in a dose-dependent fashion. However, at doses used in this study GABA had no effect on either basal level of SLI and gastrin or BBS-elicited gastrin release. These results indicate that GABA can specifically modulate BBS-induced SLI release from rat stomach.
