To compare Transcutaneous Nerve Stimulation Analgesia (TNSA) with Electroacupuncture Analgesia (AA), we observed their effect and mechanism parallelly. The results are as follows: 1. Both TNSA and AA can produce significant current-dependent analgesia. The latency of AA is shorter than that of TNSA. 2. Under the present condition (lower-frequency, lower-intensity) naloxone can antagonize partly AA but not TNSA. 3. TNSA effect could be blocked partly by deep or intradermal injection of procaine into points. However, AA effect could be almost blocked completely by deep injection and not by intradermal injection of procaine.
为比较经皮神经刺激镇痛（TNSA）和电针镇痛（AA），我们并行观察了它们的效果和机制。结果如下：1. TNSA和AA均可产生明显的电流依赖性镇痛作用。AA的潜伏期比TNSA短。2. 在当前条件下（低频、低强度），纳洛酮可部分拮抗AA，但不能拮抗TNSA。3. 将普鲁卡因深部或皮内注射到穴位，可部分阻断TNSA的效果。然而，将普鲁卡因深部注射可几乎完全阻断AA的效果，而皮内注射则不能。
