Electro-acupuncture (EA) treatment of horses to induce cutaneous analgesia also increased plasma concentrations of beta-endorphin (beta-EP) and cortisol. The magnitude of these increases did not relate consistently to the degree of EA-induced analgesia. Respiration and heart rates were also markedly increased during EA treatment. Intact female horses had higher packed cell volume and plasma beta-EP as well as lower plasma total protein than castrated male horses. Plasma cortisol, heart rate, and respiration rate did not differ significantly between sexes. None of the parameters measured before or during EA treatment provided an explanation for the differential cutaneous analgesia which depended on sex of subject and locus of stimulation as reported elsewhere.
对马进行电针治疗以诱导皮肤镇痛，也会增加血浆中β-内啡肽（β-EP）和皮质醇的浓度。这些增加的幅度与电针诱导的镇痛程度并无一致关联。在电针治疗期间，呼吸和心率也显著增加。未阉割的母马比阉割的公马具有更高的红细胞压积和血浆β-EP，以及更低的血浆总蛋白。血浆皮质醇、心率和呼吸频率在两性之间无显著差异。如其他地方所报道，电针治疗前或治疗期间所测量的参数均无法解释取决于受试动物性别和刺激部位的差异性皮肤镇痛现象。
