Abstract
Objectives : In order to verify the cardiovascular hemodynamic function of Kammaegdaejo-tang, the experiment was performed in the rats. Methods : Twelve hearts removed from male Sparague-Dawley rats weighing between 250g and 300g were perfused by the Langendorff technique with modified 37 Krebs-Henseleit's buffer solution at a constant perfusion pressure. They were randomly assigned to one of two groups, supplied with either normal saline or Kammaegdaejotang administration. Heart rate, left ventricular pressure, +dp/dt maximum, -dp/dt maximum, and -dp/dt/ +dp/dt ratio were evaluated at baseline after the administration of either normal saline or Kammaegdaejotang. Results : Kammaegdaejotang made the heart rate increasing significantly (p<0.05). Kammaegdaejotang did not effectively work on left ventricular pressure of the isolated heart(p=0.11, no significance). The significant effects of Kammaegdaejotang were observed on +dp/dt max and -dp/dt max(p<0.05). Kammaegdaejotang did not effectively work on -dp/dt/ +dp/dt ratio(p=0.24, no significance).
