 note = {第26回宇宙利用シンポジウム(2010年1月25日-26日, 宇宙航空研究開発機構宇宙科学研究本部相模原キャンパス), The Twenty-sixth Space Utilization Symposium (January 25-26, 2010: ISAS/JAXA Sagamihara, Japan), We have been organizing a working group for studying the reproduction and continuity of life under the space environment. The aim of our project is to get deep insight into the effect of space environment, especially the effects of gravity for long period of time, on reproduction. We show four results here. The first one is the evaluation of the quality of egg and embryo by respiration activity of them individually by means of micro oxygen electrode. This new method was excellent for selecting high quality eggs of bovine and gave high ratio of fertility. The second experiment using medaka also gave us the information about the seasonal change of germ cell number. It was likely that number of spermatocyte was regulated by apoptosis. The third experiment, using mice, revealed that the hyper gravity, 3G, caused decrease in food intake, however, the mice were in repletion. Measurement of hormones such as leptin, insulin and ghrelin showed starvation condition. However, NPY measurement suggested low food appetite suggesting that 3G affected the regulatory mechanism involved in NPY neurons. The fourth experiment was about human reproduction in space. The position of baby in uterus was recorded when attitude of mother was changed. The data were compared with the simulation experiments. The results suggested that space environment might increase problems on birth. We move ahead to new approaches for study on reproduction in space., 共催: 日本学術会議, joint hosting: The Science Council of Japan, 資料番号: AA0064730079},
