以牛蛙离体椎旁神经节为标本，单个方波电刺激节前纤维，细胞内记录Ｂ细胞的动作电位，在正常情况下节前单个刺激，在Ｂ细胞发生一个动作单位，刺激与反应的关系是１∶１。灌流皮质醇（０．０１μｍｏｌ／Ｌ～１μｍｏｌ／Ｌ）、皮质酮（１μｍｏｌ／Ｌ）、孕酮（０．１μｍｏｌ／Ｌ）、１７β－雌二醇（０．００１μｍｏｌ／Ｌ）、醛固酮（０．００１μｍｏｌ／Ｌ）及胆固醇（０．１μｍｏｌ／Ｌ），比较它们对神经节Ｂ细胞突触传递的快速作用。结果显示，皮质醇可使１７０个Ｂ细胞中的５２个发生突触传递阻断，另外有４个细胞出现增强效应；皮质酮可使４８个Ｂ细胞中的１７个发生阻断；孕酮可使３７个Ｂ细胞中的１５个发生阻断；１７β－雌二醇可使２１个Ｂ细胞中的８个发生阻断；醛固酮对Ｂ细胞的突触传递无明显影响；胆固醇可使２１个Ｂ细胞中６个产生增强效应。实验结果表明，皮质醇、皮质酮、孕酮及１７β－雌二醇对牛蛙交感神经节部分Ｂ细胞突触传递具有快速阻断作用，尤以孕酮的作用最显著。盐皮质激素（醛固酮）对Ｂ细胞突触传递无明显影响，而胆固醇对Ｂ细胞突触传递有增强效应。
Taking the isolated paravertebral ganglion of bullfrog as specimen, a single square wave was used to stimulate the preganglionic fibers. The action potentials of B cells were recorded intracellularly. Under normal circumstances, a single pre-nociceptive stimulus occurred in B cell, which stimulated and responded to The relationship is 1: 1. Corticosterone (0.01μmol / L ~ 1μmol / L), corticosterone (0.1μmol / L), 17β-estradiol (0.001μmol / L) and aldosterone 001μmol / L) and cholesterol (0.1μmol / L), and compared their rapid effects on the synaptic transmission of ganglion B cells. Results showed that Cortisol blocked the synaptic transmission of 52 out of 170 B cells and enhanced the effects of 4 other cells. Corticosterone blocked 17 of the 48 B cells. Progesterone Blocked 15 of 37 B cells; 17β-estradiol blocked 8 of 21 B cells; aldosterone had no significant effect on B cell synaptic transmission; cholesterol caused 21 B Six of the cells produce a booster effect. The experimental results show that cortisol, corticosterone, progesterone and 17β-estradiol have a rapid blocking effect on the synaptic transmission of some B cells in the sympathetic ganglion of bullfrog, especially progesterone. Mineralocorticoid (aldosterone) had no significant effect on synaptic transmission of B cells, while cholesterol increased the synaptic transmission of B cells.
