Effect of prostaglandin F2 alpha on temperature and behaviour of centrally sympathectomized rats.
Prostaglandin F2 alpha (PG F2 alpha) in doses of 1 and 10 micrograms applied intraventricularly causes a rise in body temperature and exerts a sedative action on rat behaviour. Chemical sympathectomy of the central nervous system (CNS) induced by a twofold intraventricular administration of 250 micrograms of 6-hydroxydopamine reduces the influence of PG F2 alpha on the body temperature and behaviour. Reserpine administered to rats with chemical sympathectomy of the central nervous system reverses or prevents the PG F2 alpha action on body temperature of the animals. The results of the experiments seem to indicate that the central monoaminergic mechanisms play a role in the central action of PG F2 alpha on body temperature and behaviour.
