采用乙醛酸诱发荧光组织化学方法显示大鼠肾上腺髓质儿茶酚胺(CAs),并以Leitz MPV—2型显微荧光光度计测量了CAs荧光强度。实验结果表明;创伤性休克大鼠肾上腺髓质CAs荧光强度较正常对照组明显减弱。电针“人中”“承浆”穴后,肾上腺髓质CAs荧光强度显著增强,表明电针可使CAs自肾上腺髓质释放耗竭减少。以上的形态学观察提示;这可能是电针有利于抗创伤性休克的作用之一。
Catecholamines (CAs) of rat adrenal medulla were visualized by using glyoxylate-induced fluorescence histochemistry. CAs fluorescence intensity was measured by Leitz MPV-2 micro-fluorimeter. Experimental results show that traumatic shock rats adrenal medulla CAs fluorescence intensity was significantly weaker than the normal control group. Electroacupuncture in “human” “Cheng pulp” point, the CAs fluorescence intensity of the adrenal medulla significantly increased, indicating that EA can reduce the release of CAs from the adrenal medulla. The above morphological observation suggests that this may be one of the effects of EA on traumatic shock.
