The opisthonephric kidney of juvenile fifteen spined stickleback (Spinachia spinachia (L.)) has been studied by light and electron microscopical investigation. The renal portal system and microcirculation has been demonstrated by casts of coloured plastic Microfil. Glomeruli are well vascularized as revealed by perfusion fixation. They contribute to the formation of urine in collaboration with a proximal tubule segment I that shows resorptive capacity. Epithelial cells of the proximal tubule segment II, which make up the bulk of the nephronic tubular mass are supposed to constitute very active secretory elements. The possible role of mucus secretion in the collecting duct-urinary duct system is discussed. Juxtaglomerulcar cells have been seen in various stages of secretion.
对十五棘刺鱼（Spinachia spinachia (L.)）幼鱼的后位肾进行了光镜和电镜研究。通过彩色塑料微丝铸型展示了肾门静脉系统和微循环。灌注固定显示肾小球血管丰富。它们与具有重吸收能力的近端小管节段I协同作用，参与尿液的形成。构成肾小管大部分的近端小管节段II的上皮细胞被认为是非常活跃的分泌元件。讨论了黏液分泌在集合管 - 输尿管系统中的可能作用。观察到球旁细胞处于不同的分泌阶段。
