A systemic examination on the small granule-containing (SGC) cells in rat superior cervical ganglia was conducted by conventional and cytochemical electron microscopy including chromaffin, argentaffin and uranaffin reactions. According to the fine structure of dense cored vesicles (DCVs) in the cytoplasm, three types of small granule-containing (SGC) cells were revealed--Type I: 90-160 nm vesicles with cores of moderate or low electron density; Type II: 130-330 nm vesicles, polymorphic with highly electron dense cores; Type III: elongated vesicles (170 nm x 60 nm) with cores of moderate to low electron density. The majority of SGC cells were the Type I cells (78%) and Type II and III cells made up 13% and 9% of SGC cell population, respectively. Cytochemical results demonstrated that only the Type II cells displayed a positive chromaffin reaction and all three types of SGC cells showed argentaffinity and uranaffinity. The present study is the first to demonstrate the argentaffin reaction at ultrastructural level in SGC cells of sympathetic ganglia. Based on the results of the present study we also concluded that (1) the DCVs of Type II SGC cells contained noradrenaline and (2) biogenic amines and nucleotides (ATPs) coexisted in the DCVs of all three types of SGC cells.
