The use of antisera raised against bovine growth hormone (GH) and ovine prolactin (PRL) enabled the detection of related immunoreactive (ir) sequences of proteins in ovine pineal tissue. The isolation of PRL-like ir-material was accomplished using a

There is growing evidence that the pineal gland has antineoplastic properties which, however, can only partially be attributed to its hormone melatonin. While the in vivo tumor-inhibiting activity of melatonin is established, observations on its in v

A chemical analysis was instigated to investigate the identity of the luteinizing hormone (LH)-like immunoactivity present in ovine pineal protein homogenates. Isolation of pineal LH-like material was accomplished using a 0.1 M ammonium sulphate (pH

A method is described for the determination of the neurohormone contents of ovine pineal tissue by radioimmunoassay (RIA) after successive fractionation on gel filtration in formic acid and reverse-phase liquid chromatography (HPLC). This method give

Former work has shown that crude extracts of ovine pineal glands probably exert a stimulating activity on the release of gonadotropins of anterior pituitaries in vitro. By aqueous extraction followed by ultrafiltration through anisotropic membranes h

Modifications of the release of neurosecretory products of the pars intercerebralis of larvae of Pieris brassicae are implied by ultrastructural observations after injection of 6- l -erythrobiopterin. A very marked accumulation of granules, especiall

Previously we were able to isolate by simple and mild methods from an aqueous sheep pineal extract an inhibiting principle action on the anterior hypophysis of male rats in vitro. This substance could be located by paper electrophoresis. In the prese

Aqueous extracts of sheep pineal bodies were separated on Sephadex G-25. A low molecular Sephadex G-25 fraction F4 was filtrated on Sephadex G-10. Several distinct peaks could be detected showing excitation and fluorescence maxima resembling those of
