ABSTRACT
In order to explore new ways in restraining the ascending blood pressure, this paper reports a research on the effects of multi-mode audio frequency pulse modulating laser irradiation with electrical stimulation on the hemorrheology and blood pressure of the spontaneously hypertensive rats (SHR). Forty male SHR were randomly divided into four groups: Group A (control), Group B (treated with electrical stimulation on stomach 36 point (ST-36)), Group C (treated with low level pulse laser irradiation on Erjian acupuncture point), Group D (low level laser irradiation together with electrical stimulation on Erjian acupuncture point and ST-36). Laser irradiation lasted for 45 min/ day, while electrical stimulation lasted for 30 min/day. After 10 days' treatment, we compared the hemorrheology and blood pressure of the rats in the four groups. The results were that values of hemorrheology in group A and group C were obviously improved compared with those in the other two groups. Meanwhile, the blood pressures in the three treated groups (B, C, and D) were lower than in the control group after the treatment, and the value of the rats in group A was the lowest. In conclusion, the treatment the laser irradiation combined with electrodes stimulation on spontaneously hypertensive rats brought better results of hemorrheology and blood pressure in the tested rats.
