【摘要】 本文用光镜和彩色图象分析系统 ,研究了雌性鲫鱼尾部神经分泌系统Dahlgren细胞及细胞化学的季节性变化特点 ,结果发现尾部最后 4～ 6节脊髓中Dahlgren细胞的蛋白质含量从春季到夏季逐渐减少直到全年中的最低水平 ,而从夏季到秋季蛋白质含量却逐渐增加直到全年中的最高水平 ,这之后又逐渐减少直到春季含量的水平。各季节间的蛋白质含量的差异均极显著 ,上述Dahlgren细胞蛋白质含量计量学的变化呈现出与卵巢同步发育的关系。从而为鱼类尾部神经分泌系统与鱼类繁殖生物学的相关性提供了新的计量学依据。更多还原

【Abstract】 The seasonal changes of cytochemistry in the Dahlgren cells of the caudal neurosecretory system in Carassius auratus are quantitatively studied under the microscope and the color image analysis system.The results are as follows:In the caudal spinal cord which is in the 4th～6th vertebrae counting backwards,the protein content in the Dahlgren cells decreases from spring to sunmer ,and until is lowest in whole year,while increases from summer to autumn,and until is highest in a whole year.Afterwards,the protein content decreases by the level of protein content during spring.The difference of protein content between two immediate seasons is very obvious.It provides the new quantitative basis for the relativity between the caudal neurosecretory system and the breeding biology of fish that the changes of quantitative analysis of the Dahlgren cells above reveal the synchro-development law between the Dahlgren cells and the ovary of fish.更多还原
