Abstract
  1. The presence of insulin-like substances has been demonstrated by immunocytochemistry in the central nervous system of the snail Helix aspersa. 2. The immunopositivity has been observed especially in the large perikarya of the mesocerebral green cells [the cerebral green cells (CeGC) stained in green by the alcian blue:alcian yellow technique]. 3. The removal of either the mesocerebrum or the CeGC stops the growth of the snail and induces the increase of the glycogen content in the mantle edge. 4. Our results show the existence of insulin-like material in the neurosecretory cells. Previous data having demonstrated the presence of specific binding sites to insulin in the cephalic ganglia of Helix aspersa, one may suggest that insulin could play a neuromodulatory or a neurotransmittory role in the central nervous system and might control the growth.
摘要
  1. 通过免疫细胞化学方法已证实在蜗牛(Helix aspersa)的中枢神经系统中存在胰岛素样物质。2. 尤其在中脑绿色细胞的大型胞体中观察到免疫阳性反应[通过阿尔辛蓝:阿尔辛黄技术染成绿色的脑绿色细胞(CeGC)]。3. 切除中脑或CeGC会阻止蜗牛生长,并导致外套膜边缘糖原含量增加。4. 我们的结果表明神经分泌细胞中存在胰岛素样物质。先前的数据已证明在Helix aspersa的脑神经节中存在胰岛素的特异性结合位点,因此可以推测胰岛素可能在中枢神经系统中发挥神经调节或神经传递作用,并可能控制生长。
