The distribution of methionine-enkephalin-like structures in the cat thalamus after electroacupuncture was studied using an indirect immunoperoxidase technique. We have observed some alterations on the distribution of methionine-enkephalin-like fibres in the thalamus of the cat after electroacupuncture. Thus, in the nuclei habenularis lateralis and lateralis dorsalis, in the tractus mamillo-thalamicus and in the tractus habenulopeduncularis, we have found methionine-enkephalin-like fibres in the animals treated with electroacupuncture, however in such nuclei and tractus no immunoreactivity was observed in the control animals. On the contrary, after electroacupuncture we have not found methionine-enkephalin-like fibres in the thalamic nuclei centrum medianum, parascicularis and subparafascicularis, in which in the animals no pretreated with electroacupuncture, immunoreactive fibres were observed. In other thalamic nuclei such as habenularis medialis, paraventricularis anterior, centralis medialis, medialis dorsalis and in the stria medullaris no alteration on the distribution of immunoreactive fibres was observed in the animals treated with electroacupuncture in comparison with the distribution of such fibres found in the control animals. These observations suggest that the electroacupuncture might induce alterations on the distribution of methionine-enkephalin-like in certain nuclei of the thalamus of the cat.
采用间接免疫过氧化物酶技术研究了电针后猫丘脑内甲硫氨酸脑啡肽样结构的分布。我们观察到电针后猫丘脑内甲硫氨酸脑啡肽样纤维的分布发生了一些变化。因此，在外侧缰核、背外侧核、乳头丘脑束和缰核脚间束中，我们在接受电针治疗的动物中发现了甲硫氨酸脑啡肽样纤维，然而在对照动物的这些核团和束中未观察到免疫反应性。相反，电针后我们在丘脑中央中核、束旁核和束旁下核中未发现甲硫氨酸脑啡肽样纤维，而在未接受电针预处理的动物中观察到了免疫反应性纤维。在其他丘脑核团，如内侧缰核、室旁前核、中央内侧核、背内侧核和髓纹中，与对照动物中此类纤维的分布相比，接受电针治疗的动物中免疫反应性纤维的分布未观察到变化。这些观察结果表明，电针可能会引起猫丘脑某些核团中甲硫氨酸脑啡肽样物质分布的改变。
