The effects of vitrified cryopreservation on glutathione(GSH)content and mitochondrial AT-Pase activity in oocytes were investigated in zebrafish(Danio rerio)cryopreservated in different vitrification solutions for 1d,2d,4dand 8dby a chromatometry method.The results showed that the maximal survival rate was observed in the oocytes cryopreservated in group V4in which the vitrification solution was consisted of 1.5mol/L methanol,6.0mol/L ethylene glycol and 0.25mol/L sucrose,with survival rate of(48.89±2.58)%...
