The distribution of neutral and acid (sialylated and sulfated) glycoprotein in the urinary apparatus of a marine and a fresh water cottid teleost (Bull rout and Bullhead) has been studied. The renal morphology of the Bullhead Cottus gobio is similar to that of the marine Bullrout Myoxocephalus scorpius: The glomerular nephron consists of 2 tubular segments (PI and PII), leading to the collecting duct-archinephric duct system (CD/AD). Sialoglycoprotein is present in the secretion of the proximal tubule segment PII cells in breeding males of Cottus gobio, resembling the mucus production of nest building male sticklebacks Gasterosteidae. The acid mucus coat in the CD/AD system of Myoxocephalus is discussed in relation to the excretion of salts by the kidney.
对一种海洋杜父鱼和一种淡水杜父鱼（杜父鱼和大头鱼）泌尿器官中中性和酸性（唾液酸化和硫酸化）糖蛋白的分布进行了研究。大头鱼（Cottus gobio）的肾脏形态与海洋杜父鱼（Myoxocephalus scorpius）相似：肾小球肾单位由两个管状节段（PI和PII）组成，通向集合管 - 原肾管系统（CD/AD）。在雄性繁殖期的大头鱼近端小管节段PII细胞的分泌物中存在唾液酸糖蛋白，这类似于筑巢雄性刺鱼科（Gasterosteidae）产生的黏液。讨论了杜父鱼CD/AD系统中的酸性黏液层与肾脏盐分排泄的关系。
