Abstract: Cytochemical relationship between Golgi complex and dense-cored granules (DCGs) of small granule-containing (SGC) cells in rat superior cervical ganglia was examined in electron microscopy by zinc-iodide-osmium tetroxide (ZIO) method and by enzyme cytochemistry for thiamine pyrophosphatase (TPPase) and acid phosphatase (ACPase). After ZIO impregnation, al1 the saccules of Golgi apparatus and some of tubular rough endoplasmic reticulum (rER) were stained. DCGs in periphery of SGC cells were not stained, but varying degrees of dense deposits occurred in the DCGs in vicinity of Golgi trans-saccules. Both TPPase and ACPase activities were localized in one or two stacked layers of saccules on the trans side of the Golgi complex. No reaction products were demonstrated in the DCGs. From these results, we suggest that the DCGs of SGC cells in rat superior cervical ganglia are derived from the Golgi complex, and that lysosomal cleavage of protein contents in the DCGs may occur in the trans Golgi saccules.
