| pubmed-article:9839714 | pubmed:abstractText | The effects of fasting, restraint stress, and intracerebroventricular (i.c.v.) injection of somatostatin on the growth hormone secretagogue, KP-102-induced stimulation of food intake were examined in rats. KP-102-induced stimulation of food intake was observed in freely-fed rats but not in 24-h starved rats. A 90 min period of restraint stress decreased food intake, and i.c.v. administration of KP-102 counteracted the suppressive effect of restraint on food intake. I.c.v. administration of somatostatin partially attenuated the KP-102-induced stimulation of food intake in freely-fed rats, while somatostatin itself did not change food intake. These results suggest that the stimulatory effect of KP-102 on feeding behavior is evident in freely-fed rats but not in starved rats, and that the effect of KP-102 is counteracted or attenuated by stress or somatostatin. | lld:pubmed |
