Feedback effects of growth hormone on anterior pituitary function in chickens

摘要: Circulating GH concentrations were suppressed 24 h after intracerebroventricular (i.c.v.) injection of native or recombinant DNA-derived chicken (rcGH) (10 micrograms in 4 microliters vehicle) into the right lateral ventricles conscious 6-week-old cockerels. Plasma LH within 1 i.c.v. administration at doses 10 micrograms, and remained for birds injected with highest concentration GH. In contrast, plasma prolactin increased micrograms). The i.v. rcGH (at 100 micrograms/kg) did not mimic effects These results demonstrate central on pituitary function domestic fowl.
