[Influence of Cinnamomum migao H.W.Li oil on hemodynamic action in anesthetized cats].

Cinnamomum migao oil (CV-3) 0.2ml.kg-1 was intraduodenum given to anesthetized open-chest cats. Ninety minutes after treatment with the oil, the SAP and DAP were slowly reduced to 15.2% and 14.2%, respectively. At the sametime, the HR was slowed down and CO decreased. The left ventricular pressure (LVP), the left ventricular end diastolic pressure (LVEDP), dp/dtmax and Vmax were remarkably reduced respectively. The LVP-(dp/dtmax)P-1 loop was narrowed. Isosorbide dinitrate showed similar effects to CV-3.
