[The role of ear electroacupuncture on arterial pressure and respiration during asphyxia in rabbits].
This paper reports the study of the effect of ear electroacupuncture (EA) inserted in the "Er Jian" point on arterial pressure and integrated phrenic nerve discharge (IPND). The result showed that the arterial pressure was decreased and frequency of IPND was increased. The differences as follows: During spontaneous breathing, the blood pressure and IPND were -36.56 +/- 26.63 mmHg and, 2.42 +/- 1.42 spikes/10S (P less than 0.001); in excitatory period, -24.31 +/- 6.01 mmHg and, 2.16 +/- 1.12 spikes/10S (P less than 0.01) and in inhibitory period -18.26 +/- 7.04 mmHg (P less than 0.01) and, 2.07 +/- 1.07 spikes/10S (P less than 0.05). The lasting time was 26 min, 330S and 280S. We observed 20 cases with hypertension by ear electro-acupuncture. The systolic pressure and diastolic pressure of hypertension patients were decreased (P less than 0.001) and respiratory rate increased (P less than 0.05).
