title: Effects of suprachiasmatic nuclei (SCN) lesions on the circadian variations in PRA and IRI level in the rat.
abstract: 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 and IRI, diminishing significantly PRA in comparison with intact rats.
