Small granule containing cells (SGC or SIF cells) in the lower mesenteric ganglion of the guinea-pig were studied in control and experimental animals. After reserpine administration a decrease of dense population of granular vesicles was found. After injection of nialamide and dopamine to the animals in SGC cells significantly increased the number and density of granular vesicles. No real efferent synapses were found on SGC cell processes, although sites with accumulated synaptic-like vesicles, mostly with a dense core, were often observed.
对豚鼠肠系膜下神经节中的含小颗粒细胞（SGC或SIF细胞）在对照动物和实验动物中进行了研究。给予利血平后，发现致密颗粒小泡的数量减少。给动物注射尼亚酰胺和多巴胺后，SGC细胞中颗粒小泡的数量和密度显著增加。在SGC细胞突起上未发现真正的传出突触，尽管经常观察到有类似突触小泡聚集的部位，大多数小泡有致密核心。
