|Title:||Stress-induced Desensitization Of The Cardiovascular Response To Noradrenaline In Unanesthetized Rats.|

|Abstract:||The present study was undertaken in order to analyse the effect of swimming stress on the blood pressure response to noradrenaline (NA) in unanesthetized rats. Swimming induced a desensitization of the blood pressure response to NA which was not blocked by previous animal treatment with prazosin (0.1 mg/kg). However, rats submitted to stress showed increased sensitivity to the prazosin blocking effect. The results suggest that swimming-induced desensitization of the cardiovascular response to NA is mediated by alpha rather than beta-1 adrenoceptors.|
