Research of pulse wave's change of rats after kidney resection / 中华中医药杂志

ABSTRACT

Objective:To study the change rule of rats'pulse waves after kidney resection.Methods:To collect the pulse waves of femoral artery in each side of rats in Drugged state.Then do one-side kidney resection operation,after fully recover from it,collect the pulse waves again.To average the pulse waves in the same cycle length and then do the LSQ regression by 6 harmonics which are correspond with the cycle lengths,analyze the phase and the amplitude of vibration of fundamental wave and harmonics by statistical method.Results:The amplitude of vibration of the 3rd harmonics of pulse waves of femoral artery in the same side with operation and the amplitude of vibration of the 1st to 5th harmonics of pulse waves of femoral artery in the other side with operation has reinforced, the phase of the 1st and 2nd harmonics also have changed regularly.Conclusion:There're some regular changes in the pulse waves of rats after one-side kidney resection operation,which shows that the pulse waves of artery on the body surface can reflect the splanchnic changes.This research can offer some scientific foundation to the pulse-diagnosis in TCM.
