Continuous perifusion of quartered anterior pituitary glands from juvenile and adult chickens of both sexes with chicken gonadotrophin-releasing hormone-I (cGnRH-I) stimulated a spike-plateau profile of luteinizing hormone (LH) secretion. When perifu

Domestic hens were injected intraperitoneally with hypertonic or isotonic saline and killed 0.5, 1, 2, 6, 12 and 24 h later. Japanese quail, Ring doves and Zebra finches were treated in the same way and killed 2 h later. Using fos immunocytochemistry

GH administered centrally or peripherally inhibits basal or secretagogue-induced GH secretion in domestic fowl. Since the release of pituitary GH is neurally regulated by the hypothalamus, GH autoregulation may be mediated by changes in the content o

The concentration of plasma triiodothyronine (T3), thyroxine (T4), corticosterone, and glucose as well as body weight and food intake were measured in pairs of ring doves throughout a breeding cycle and during food deprivation. During courtship and i

Passive immunization of incubating ring doves with daily injections of sheep anti-chicken vasoactive intestinal polypeptide (cVIP) serum prevented the proliferation of crop sac tissue observed in control doves given nonimmune serum. Daily injections

1. Basal circulating growth hormone (GH) concentrations in sex-linked-dwarf (SLD) chickens were unaffected by the intracerebroventricular (icv) injection of 10, 50 or 100 micrograms somatostatin (SRIF). 2. The GH response to systemic thyrotropin-rele

Intracerebroventricular (i.c.v.) administration of GH-releasing factor (GRF) (at 1 or 10 μg) to anaesthetized immature (6- to 8-weeks-old) or adult (> 24-weeks-old) domestic fowl had no effect on basal GH concentrations in peripheral plasma, but sup

The i.c.v. administration of 0·1 or 10 μg ovine (o)GH to 12- to 16-week-old hypothyroid chickens of a sex-linked dwarf (SLD) strain suppressed the basal plasma GH concentrations, measured 24 h afterwards. The GH response of the oGH-injected SLDs to

Peripheral plasma concentrations of GH in adult chickens were increased, in a dose-related manner, between 5 and 30 min after the intracerebroventricular (i.c.v.) injection of 0·1 or 10 μg TRH. In contrast, i.v. administration of comparable doses o
