摘要: Based on previous studies we hypothesize that under stress conditions catecholamine-induced hyperglycemia contributes to enhance cortisol production in head kidney of rainbow trout. Therefore, treatment with propranolol (β-adrenoceptor blocker) should reduce the elicited by and, therefore, expected reduced glucosensing response and kidney. Propranolol was effective blocking most effects catecholamines liver energy metabolism resulting a lower glycemia stressed fish. The decreased fish treated observed along transcription genes involved synthetic pathway, which supports our hypothesis. However, changes putative parameters assessed were scarce general did not follow noted glucose levels plasma. Furthermore, circulating change parallel glycemia. As whole, present results suggest could participate regulation pathways but other factors are also likely involved. trout different depending time passed after onset; direct or indirect involvement catecholaminergic release deserves further investigation.
