Norepinephrine-like effects of neuropeptide Y on LH release in the rat.


Neuropeptide Y, a recently isolated neuropeptide exhibited norepinephrine-like effects on LH release after intracerebroventricular administration at doses from 0.5 to 10 micrograms. While it promptly suppressed LH release in ovariectomized rats, there was a dose-related stimulation of LH secretion in ovarian steroid primed-ovariectomized rats. In view of… (More)
