[Role of neuropeptides in the pathogenesis of pain syndrome in autonomic and sensory polyneuropathy of occupational etiology and their role in the therapeutic action of laser acupuncture].

Biochemical studies of opiate system in patients with occupational diseases showed the role of the central pain regulating system inducing the pain syndrome in autonomic and sensory polyneuropathy caused by occupational factors. Increased production of the pain-reducing endogenic neuropeptides such as endorphin and leucine enkephalin was found one of the He-Ne laser acting principles which restore the pain adaptation in human. A repeated course of laser therapy would normalize the content of both neuropeptides. Blood levels of neuropeptides may serve for evaluating the pain syndrome and estimating of laser therapy effects.
