Involvement of α-adrenoceptors in norepinephrine-induced prostaglandin E2 release by rat pineal gland in vitro

Rat pineal glands incubated in vitro with 10 or 100 μM norepinephrine (NE) released 51% and 415% more prostaglandin E2 (PGE2) to the medium than in the absence of NE. Phentolamine (10 μM) prevented fully the effect of NE at both concentrations, whereas propranolol failed to affect it significantly....
