1.将东北星海星桡神经水提液局部涂抹于离体卵巢的一部分，持续适当时间，然后在卵巢壁上划小缝，仅在处理部分出现强烈的排卵现象.卵巢未处理部分的卵子通过卵泡层粘附在性腺壁上。用神经提取物处理的结扎卵巢碎片中的卵子失去了卵泡并经历了成熟。发现这些蛋是可以自由移动的。不使用神经提取液也能诱导人工产卵;无镁海水浸泡的卵巢碎片在一定时间后产卵，而无钙海水处理的卵巢碎片在适当时间后再添加钙后产卵.无钙海水处理的卵巢内发生卵泡破裂。使用收缩诱导剂治疗会导致…
1. When a water extract of radial nerves of the starfish, Asterias amurensis, was locally applied to one part of an isolated whole ovary for an appropriate period and then small slits were made on the ovarian wall, intense discharge of eggs occurred only in the treated portion.2. Eggs within the nontreated part of the ovary were observed to adhere to each other and to the gonadal wall by means of the follicle layer surrounding them.3. Eggs within ligated ovarian fragments which had been treated with nerve extract lost their follicles and underwent maturation. These eggs were found to be freely movable.4. Artificial spawning could be induced without using nerve extract; ovarian fragments immersed in Mg-free sea water released their eggs after a certain interval, while those treated with Ca-free sea water for an appropriate period spawn after subsequent addition of calcium.5. Breakdown of follicles occurred within an ovary treated with calcium-free sea water.6. Treatment with contraction-inducing agents suc...
