The effect of chronic sodium loading on the level of plasma atrial natriuretic peptide (ANP) and on plasma renin activity (PRA), as well as on the renal excretory function was studied. Fifty-six standardly bred Long Evans rats were divided into three

PRA and IRI were determined at 8 a.m., 4 p.m. and midnight (MN) in SCN lesioned and intact rats. In control animals, PRA was highest at 4 p.m., while IRI showed higher values at 8 a.m. and MN. SCN lesions abolished circadian variations in both PRA an
