Effect of losartan on arterial blood pressure and unit dischargings of habenular neurons in rat / 吉林大学学报(医学版)

ABSTRACT

Objective:To investigate whether the habenula takes part in the depressor effect of losartan.Methods:Arterial blood pressure,heart rate and the unit dischargings of habenular neurons in rat were recorded simultaneously.Results:Arterial blood pressure was apparently decreased by 10 mg/kg losartan intraperitoneally(ip),but heart rate did not change;63.64% (21/33) unit dischargings of habenular neurons was increased in the rate of discharges.Conclusion:The depressor effect of losartan (ip) may be involved in the excitation of habenular neurons by lsoartan(ip).
