Using antisera to synthetic luteinizing hormone-releasing factor (LRF) and antisera labeled with fluorescein isothiocyanate or peroxidase, it was possible in various physiological and experimental conditions to determine the topography of the LRF secretory cells in the guinea pig. The axons of these cells form a preoptico-infundibular LRF pathway, which(More)
Miniglucagon, the COOH-terminal (19-29) fragment processed from glucagon, is a potent and efficient inhibitor of insulin secretion from the MIN 6 beta-cell line. Using the rat isolated-perfused pancreas, we investigated the inhibitory effect of miniglucagon on insulin secretion and evaluated the existence of an inhibitory tone exerted by this peptide inside(More)
The effect of chronic renal failure on the lipid and apolipoprotein concentrations of plasma, very low density lipoproteins (VLDL), intermediate density lipoproteins (IDL), low density lipoproteins (LDL) and high density lipoproteins (HDL) was studied in an experimental uremic rat model. Control rats were sham-operated and were divided into adlibitum-fed(More)
