针刺“曲池”、“臂臑”对“人中”、“承浆”穴区儿茶酚胺阳性神经的影响

Influence of Electroacupuncture on Subcutaneous Catecholaminergic Nerves in “Renzhong”, “Chengjiang” Acupoints

利用荧光组织化学方法,观察循经针刺手阳明大肠经上的“曲池”、“臂臑”两穴对交会经穴“人中”和非交会经穴“承浆”两穴区皮下儿茶酚胺阳性神经的密度、面积及荧光强度的变化。结果发现①针刺可使“人中”穴区儿茶酚胺阳性神经的荧光强度明显增高(P<0.05),同时儿茶酚胺阳性神经纤维的面积有增大的趋势,但无统计学意义(P>0.05),②针刺对“承浆”穴区儿茶酚胺阳性纤维的密度、面积及荧光强度均无明显影响。表明针刺可循经影响同经线上的其它穴区皮下自主神经的活动。

Using fluoro-histochemical method, we studied the influence of the electroacupuncture on 'Quchi' and 'Binao' acupoints of Large Intestine Meridian upon the changes of the density,the area and the fluorescent intensity of the subcutaneous catecholaminergic (CA) nerves in 'Renzhong', an convergent acu-point of the Large Intestine Meridian, and 'Chengjiang', an acupoint in another meridian. The results were as follows:(l) Electroacupuncture significantly strengthened the fluorescent intensity of subcutaneous CA nerves in 'Renzhong' acupoint (P<0. 05), while the area of the CA nerves had no changed (P >0. 05). (2) Electroacupuncture had no influence on the density,the area and the fluorescent intensity of the subcutaneous CA nerves in 'Chengjiang' acupoint. The results suggest that electroacupuncture along the meridian may in-fluence the activity of the sympathetic nerves of the acupoints in the same traditional Chinese meridian.
