The effect of arginine vasopressin (AW) on the contents of cAMP and cGMP in the isolated right atria and ventricular muscle strips was observed at the concentration possessing negative inotropic effect on the cardiac muscle (0.8ng/ml).

• 本实验采用大鼠离体右心房、右心室肌条模型；研究了对离体心肌有负性变力作用浓度的加压素(0.；8ng/ml)对右心房、右心室肌条cAMP和cGMP含量的影响。
