Abstract

Intracerebroventricular administration of PGF and PGE2 suppressed food intake in several feeding models. PGF (20 μg) and PGE2 (20 μg to 1 μg) suppressed food intake following a 24 hour starvation. PGF (20 μg) and PGE2 (20 μg) suppressed food intake following central administration of the feeding induces norepinephrine and muscimol. These prostaglandins also suppressed stress induced eating using the tail pinch model at doses of 20 μg, 10 μg and 5 μg with eating returning to control levels at the 1 μg dose. D-Ala Methionine Enkephalin failed to alter the suppressive effects of PGF and PGE2 at a dose of 1 μg but successfully reversed the effect of PGF at a 10 μg dose while still having no effect on PGE2 suppression of feeding.
