Somatostatins, somatostatin-14, somatostatin-28, and desAA [D-Trp8]-somatostatin, with differential potencies, act in the brain to reverse chemical-induced hypothermia and to produce hyperthermia. Somatostatins are more potent and loger acting than prostaglandin E2 in producing hyperthermia. Hyperthermia, induced by somatostatins, is not prevented by previous treatment with the prostaglandin synthesis inhibitor indomethacin. Somtostatins given to obese ob/ob mice prevent development of lethal hypothermia and result in maintenance of euthermia. Continuous infusion of somatostatins results in desensitization to the hyperthermic effects of these peptides. Endogenous somatostatins may be involved in regulation of body temperature.

An intracisternal injection of somatostatin-28 produced hyperthermia in rats at cold, thermoneutral, warm ambient temperatures. The hyperthermic response to somatostatin-28 was not prevented by pretreatment of rats with the following agents: alpha-methylparatyrosine, phenoxybenzamine, propranolol, sulpiride, atropine, methysergide or naloxone. Somatostatin-28 prevented hypothermia induced by bombesin and gamma-MSH when it was administered simultaneously, but it left the hyperthermic response to TRH intact. The results indicate that somatostatin-28 produces hyperthermia by elevating a "set point" or regulated level of temperature. Under the conditions tested, the hyperthermic response to somatostatin-28 does not appear to be dependent on muscarinic cholinergic, serotonergic, alpha- or beta-adrenergic, dopaminergic or endogenous opiate system.
