The peripheral administration of pyrogens has been shown previously to affect the activity of central noradrenergic neurons, but the effects have been variable and no consensus has emerged regarding their functional significance. Because norepinephrine (NE) microdialyzed into the preoptic area (PO)
The effects of the alpha-agonist clonidine and the beta-agonist clenbuterol on body temperature of rats kept at high ambient temperature (28 degrees C) were studied. Both drugs induced a dose-dependent significant increase in temperature. The clonidine-induced hyperthermia was blocked by various
Intrapreoptic (IPO) microinjections of various agents cause unavoidable brain tissue injury, often resulting in prostaglandin (PG)-mediated core temperature (Tc) rises. However, IPO microinjection of the alpha 2-adrenoreceptor agonist clonidine (Clo) generally evokes a Tc fall, seemingly avoiding
