摘要: Abstract Bilateral lesions in the locus coeruleus (LC) of rats induced a urinary disorder and hyperdipsia. Dilatation bladder, retention hematuria with bleeding originating from occurred immdiately after lesioning continued for 2–5 days. Water intake increased 4 days lesioning. This hyperdipsia persisted at least then gradually returned to control level. Food decreased first 5 days, Lesions ascending dorsal bundle (DB) LC also produced hyperdipsia, but not disorder. Destruction ventral (VB) noradrenaline (NA) neurons medulla oblongata did affect eating, drinking or urination. The LC- DB-lesioning caused significant reduction NA whole forebrain except hypothalamus, whereas VB-lesioning reduced hypothalamus. In LC-lesioned animals, no changes were observed serum osmolarity, Na + , K albumin glucose serum, excretion urine water-loading test.
