Japonicus and analyzed the role of animal process of oocyte during ovulation and oocyte maturation. What's more, we studied the role of microtubules and microtubule organizing center upon GV migration. The oocyte of A. japonicus connects to the follicle via animal pole process. When placed in normal sea water, ovulation started spontaneously.

Study the bioactivity of the n-HA/PA66 composite and the effects it would be to body's metabolism of calcium and phosphorus ion in vivo.(3) Study the osteo-conductivity and the ability to repair bone defect of the porous n-HA/PA66 composite and the feasibility use it as the scaffold of bone tissue engineering. Objects and Methods as follows: 1.To evaluate the biocompatability of nano-hydroxyapatite crystals and polyamide composite (n-HA/PA66) with the L929 cells.To proceed the morphological observation and take pictures of L929 cells after 1d,2d,4d,and 7d of co-cultured with extract of n-HA/PA66 ,and direct contact with n-HA/PA66.To determine light absorbtion value of every hole under 500 nm with enzyme linked immunity instrument after 1 d,2 d,4 d,and 7 d of contact of n-HA/PA66 extract with L929 cells,and direct contact with n-HA/PA66.In the meanwhile calculate the relative multiplication rate of cells,and evaluate them by six degree tests for cytotoxicity. To investigate the acute and chronic toxic reaction on the whole body induced by the new nano-hydroapatite crystals and polyamide composite(n-HA/PA66)after implanting in vivo and its effects on partial constitution of animal organs after implanting in vivo,and evaluate the potential and degree of subcuticular stimulation reaction.
