A high incidence of lordotic curvatures has been detected in commercial cultures of Sparus aurata. We have studied juvenile and adult lordotic specimens to elucidate whether the subcommissural organ and its secretion, the Reissner's fiber, play any role in the development of this syndrome. Animals were X-radiographed and then the brain and spinal cord dissected out and processed for light microscopy. Adult lordotic fishes had a well developed swim-bladder whereas juvenile did not. The central canal of the spinal cord showed dramatic alterations, and an altered Reissner's fiber was always present. Our histochemical results suggested a hyperactivity of the subcommissural organ in lordotic fishes.
在金头鲷的商业养殖中已检测到脊柱前凸弯曲的高发生率。我们研究了幼年和成年脊柱前凸标本,以阐明连合下器官及其分泌物——赖氏纤维是否在该综合征的发展中起任何作用。对动物进行X射线摄影,然后取出脑和脊髓并进行处理以用于光学显微镜检查。成年脊柱前凸鱼有发育良好的鳔,而幼年鱼则没有。脊髓中央管显示出显著变化,并且总是存在改变的赖氏纤维。我们的组织化学结果表明脊柱前凸鱼的连合下器官功能亢进。
