title: [Study of the peptide hormones of the hypothalamo-postpituitary system of the dromedary, Camelus dromedarius, (Camelidae, Mammalia) of Tunisia].
abstract: Ocytocin and vasopressin are two nonapeptides of the hypo thalamo-Post-hypophysary system. They are isolated and purified from dromedary post-hyphophysis, freshly collected in the meat centers of the south of Tunisia. The use of three chromatographies steps were found to be essential in obtaining high Pure hormones. These steps cousist in a sephadex G25 gel filtration and two successive High performance liquid chromatographies: H.P.L.C. The analysis of the two hormones by thin layer chromatography and Radioimmunoassays, and the identification of the amino-acid composition demonstrate that camel vasopressin is a 8 arginin vasopressin but ocytocin is identic to the other hormones isolated from different animal species.
