本文目的是研究ＤＲＧ神经元膜谷氨酸受体亚型的分布及其共存情况。实验在ＤＲＧ分离细胞上应用膜片带技术记录ＮＭＤＡ－，ＫＡ－和ＱＡ／ＡＭＰＡ－激活电流。在受检的３７个细胞中７０．３％的细胞对ＮＭＤＡ敏感；１８．９％的细胞对ＫＡ敏感；５６．８％的细胞对ＱＡ敏感。其分布的情况是：单独存在一种受体的细胞为１５个；二种受体共存的细胞为１３个；三种受体共存的细胞为４个．另外有４个细胞三种受体均无。
The purpose of this paper is to investigate the distribution and coexistence of membrane glutamate receptor subtypes in DRG neurons. Experiments Diaphragm techniques were used to record NMDA-, KA-, and QA / AMPA-activated currents on DRG-isolated cells. 70.3% of the 37 cells tested were sensitive to NMDA; 18.9% of the cells were sensitive to KA; and 56.8% of the cells were sensitive to QA. The distribution is: there are 15 cells with one receptor alone; 13 cells with two receptors coexisting; and 4 cells with three receptors coexisting. There are four other cells in three receptors were not.
