摘要 本试验利用周林频谱仪(WS-302)照射玻璃化冷冻前后小鼠桑椹胚,研究对其体外发育的影响,结果表明:胚胎在10%EG溶液中处理5min后移入EFS30中处理1min的二步法冷冻组,解冻后经照射5~20min后的胚胎发育率(95%~100%)与对照组(94%)比较无显著性差异(P>0.05)。当在EFS40中处理1min的一步法冷冻组的胚胎,照射后发育率由对照组的54%提高到97%差异极显著(P<0.01)。改用GFS40一步法冷冻的胚胎照射后的发育率也明显高于对照组(P<0.05)。另外,对冷冻前胚胎进行照射,其解冻后发育率(87%)也得到了显著提高(P<0.01)。 This experiment was to study the developmental ability of mouse morulae which were irradiated by Zhoulin Bio-Frequency Spectrum Generator (WS-302 ) before or after being frozen. Mouse morulae were pretreated in 10% EG for 5 min,then pipetted into EFS40for another 1 min treatrnent and plunged into LN2(two-step) for storage. After thawing the embryos were irradiated by WS-302 for 5~20 min. The rate of development was 95%~100% in vitro culture, which was not differ from the control (94 % ) group (P>0. 05). However,mouse morulae were frozen only in EFS40 for 1 min(one-step),the rate of development was 97 % after the thawed embryos were irradiated by WS-302 and the control was 54%, the difference was greatly significant (P<0. 01).When the morulae were vitrified in GFS40, the developmental rate was signicantly higher than the control (P<0.05) after the thawed embryos were irradiated by WS-302. The developmental rate was also significantly higher than the control when mouse morulae were irradiated by WS-302 before freezing(P<0.01 ).
