Suppression of food intake by porcine gastrin (possible role as satiety factor).
In this study 150 male and female albino rats were divided into 5 groups (30 per group) for control (physiological saline) 4, 6, 8 and 10 micrograms.kg-1 b.wt. intraperitoneal injection of crude porcine gastrin, after 12 h fast. All the animals were given normal rat chow and drinking water following the injection of crude gastrin. It was found that the crude gastrin administered significantly decreased food intake by 21.7, 25.4, 29.8 and 32.0% at gastrin doses of 4, 6, 8 and 10 mg.kg-1 b.wt. respectively (P less than 0.01, t-test). Suppression of food intake was significantly correlated with dose of gastrin r = -0.984 (P less than 0.01). It is concluded that crude gastrin suppresses food intake in rats and many act as a satiety factor in these animals.
