Description

The aim of this study is to find the most suitable Medaka strain for the evaluation of effects of cosmic rays irradiation on medaka spermatogenesis. Males of 4 Medaka inbred strains (Hd-rR, AA2, HNI. And KAGA) were exposed to high-energy carbon nuclei and it was revealed that males of Hd-rR were the most susceptible to the irradiation. To investigate the effects of high-energy carbon nuclei exposure on Medaka spermatogenesis, males of a transgenic strain (olvas-GFP), of which sperm express GFP and are fluorescent, were exposed to high-energy carbon nuclei. Within 4 weeks after the exposure, almost all of the sperm were fluorescent and the number of sperm decreased, suggesting that high-energy carbon nuclei killed spermatogonia and remaining spermatogonia continued to produce normal sperm after the exposure in Medaka testis.
