The chromaffin cells of the adrenal homologue of Salmo gairdneri R. have been studied by light and electron microscopy. The chromaffin tissue was localised in the head kidney adjacent to the wall of the proximal part of the cardinal veins and their main branches. Specific histochemical techniques failed to demonstrate different types of chromaffin cells. With the electron microscope two different types of chromaffin cells were observed. The first type, characterised by numerous dense cytoplasmic granules of average diameter 90 nm, was interpreted as a noradrenalin cell; the second type was characterised by the presence of moderately electron-dense granules of average diameter of 85 nm, and was interpreted as an adrenalin cell. The reaction for acetylcholinesterase activity was present on nerve terminals and sometimes in the vacuolar membrane systems of both chromaffin cells.
利用光学显微镜和电子显微镜对虹鳟肾上腺同源组织中的嗜铬细胞进行了研究。嗜铬组织位于头肾，毗邻主静脉近端及其主要分支的管壁。特定的组织化学技术未能显示出不同类型的嗜铬细胞。通过电子显微镜观察到两种不同类型的嗜铬细胞。第一种类型的特征是有许多平均直径为90纳米的致密细胞质颗粒，被解释为去甲肾上腺素细胞；第二种类型的特征是存在平均直径为85纳米的中度电子致密颗粒，被解释为肾上腺素细胞。乙酰胆碱酯酶活性反应存在于神经末梢，有时也存在于两种嗜铬细胞的液泡膜系统中。
