Última A 66-kDa protein of bovine hypophyseal Pars tuberalis induces luteinizing hormone release from rat Pars distalis Biocell Lafarque,Martha; Oliveros,Liliana. In this study, evidence for a factor secreted by bovine hypophyseal pars tuberalis that stimulates luteinizing hormone (LH) release from rat pars distalis cells is shown. The secretion products of bovine pars tuberalis cells into the culture medium were assayed on dispersed rat pars distalis cells in 30 min incubations and superfusion experiments. The culture medium from pars tuberalis total cell populations, added at a dose of 6 μg per tube, induced the greater LH release from pars distalis cells, without effect on follicle stimulating hormone (FSH) release. After pars tuberalis cells separation on a discontinuos Percoll gradient, only the culture medium of cells from 50 and 60% strength Percoll were able to release LH from rat pars distalis...

Nothura maculosa is a South American Tinamidae with a marked seasonal reproductive pattern. This work describes ovarían seasonal changes in this species related to gonadotrope (GTHs) population. Ovary and pituitary samples were collected monthly from adult birds during four annual periods. They were fixed in Bouin's solution and processed for light microscopy. The data of post-fixation gonadal weight were analysed using STATISTIX 4.0. Histological sections of the ovaries were stained with H/E, PAS and Goldner-Masson trichrome. Single and double immunostaining were applied on pituitary sections with anti-chicken-FSH and anti-chicken-LH antibodies. The samples were analysed in quarterly periods of the year, Pl: March-May (resting stage); P2: June-August...
