Abstract

OBJECTIVE:

To observe the effect of electroacupuncture (EA) of different acupoints on blood pressure (BP), plasma angiotensin (Ang) II, aldosterone (ALD) and atrial natriuretic peptide (ANP) of SHR, so as to observe the relative specificity of effects of acupoints.

METHODS:

A total of 60 SHR were randomly divided into model, Quchi (LI 11), Zusanli (ST 36), Shenmen (HT 7), Jianyu (LI 15) and non-acupoint groups, with 10 cases in each. Other 10 Wistar rats were composed of normal group. EA (2 Hz, 2 mA) was applied to LI 11, ST 36, HT 7, LI 15 and non-acupoint for 30 min, followed by measuring BP with BP-6 system. Plasma Ang II, ALD and ANP contents were assayed by radioimmunoassay.

RESULTS:

Compared with control group and pre-treatment, both systolic pressure (SP) and diastolic pressure (DP) of Quchi (LI 11), Zusanli (ST 36) and Shenmen (HT 7) groups lowered significantly (P<0.05). No significant differences were found in the SP and DP of Jianyu (LI 15) and non-acupoint groups (P>0.05). After EA, the SP of Quchi (LI 11) and Shenmen (HT 7) groups were significantly lower than that of Jianyu (LI 15) and non-acupoint groups (P<0.05); and the DP of Quchi (LI 11), Zusanli (ST 36) and Shenmen (HT 7) groups were markedly lower than that of Jianyu (LI 15) and non-acupoint groups (P<0.05). Compared with normal group, the contents of plasma Ang II and ANP of model group decreased significantly, and plasma ALD level of model group increased remarkably (P<0.05). Compared with model group, plasma AngII levels in Quchi (LI 11), Zusanli (ST 36) and Shenmen (HT 7) groups and ALD in Zusanli (ST 36) and Shenmen (HT 7) groups lowered significantly (P<0.05), and plasma ANP content in Shenmen (HT 7) group increased obviously (P<0.05).

CONCLUSION:

EA of LI 11, HT 7 and ST 36 can effectively lowered both DP and SP in SHR, which may be closely related to its effects in regulating the contents of Ang II , ALD and ANP.
