By using the glyoxylic acid to induce fluorescence histochemieal method, the catecholamines (CAs) in the adrenal medulla of rats were demonstrated。The CAs fluorescent intensity was measured with Leitz MPV-2 microflurophotometer. The results showed that the CAs fluorescent intensity in the adrenal medulla of rat with traumatic shock was much decreased than that of the normal control group. The CAs fluorescent intensity was in the adrenal medulla obviously increased after using electroacupuncture (EA) at "Renzhang" and "Chenjiang" points. Our results also indicated that the EA might play a certain role in regulating the level of plasma CAs during the traumatic shock process. Therefore, The depletion of CAs was reduced from the rat's adrenal medulla, this could be one of the benificial factors in using the EA antitraumatic shock.
