The genetic inactivation of eggs is the first key stage of androgenesis in fish. In order to observe the effect of UV irradiation for the inactivation of female nucleus of zebrafish the eggs were irradiated by UV with solution-free, pure water, Ringer's solution and Cortland solution. The results showed that abnormal fry were obtained in all groups and haploids were validated. But irradiation with solution was confirmed it could not inactive fully female nucleus and the fertilization rate of the eggs irradiated with pure water was very low.

雌核灭活是雄核发育的第一个关键步骤，为研究紫外线对斑马鱼卵的雌核灭活效果，将斑马鱼的卵采用干法或置于纯水、Ringer氏溶液和Cortland鱼用生理盐水进行紫外线照射，结果表明，各种方法中均得到畸形鱼苗，并经染色体检查大多为单倍体；四种方法中在Cortland鱼用生理盐水中灭活效果最好，120 mJ/cm2紫外线可以使雌核完全灭活；干法处理不能达到雌核完全灭活的目的，在纯水中灭活后的卵子受精率较低。

RESULTS: Thirty-two cases were anencephalia, 31 hydrocephalus, 4 hydroancncephalus, 11 neningocele or encephalomeningocele, 25 spinal meningocele with myeloschisis, 12 Dandy-Walker deformity, 11 schizencephaly of forebrain and 22 choroid plexus cyst among the 148 fetuses.

The results were analyzed with the statistical software package spss10.0.results ①between two groups,there was no significant difference about the affection of age,sex and the destribution and location of aneurism on prognosis outcome(p＜0.05).however,the grading of hunt hess and fisher in group a(gos＞3) showed significantly lower than in group b(gos≤3),（p＜0.001）;② there was no significant difference in the frequency of heart rate, st elevation, st depression,t wave inversion,u wave inversion and ventricular arrhythmia(p＞0.05).the frequency of abnormal q wave, supraventricular arrhythmia and the ecg scores in group a showed significantly lower than in group b （p＜0.05,p＜0.001）;③the ecg scores was the most powerful multivariate risk stratified(ecg ≥5 vs ecg＜5; p=0.002,or=0.010,95%ci 0.001~0.173).conclusion the ecg score, a new and simple method of semi quantification, was a powerful risk predictor for patients with sah.

应用spss10.0 统计包分析结果。结果①在年龄、性别、动脉瘤生长部位影响动脉瘤性sah预后方面，两组病例无明显差异（p＞0.05）。而按sah后hunt hess分级和fisher分级，gos＞3病例的分级要明显低于gos≤3的病例的分级（p＜0.01）；②两组在心率、st段抬高、st段压低、t波倒置、u波倒置、室性心律失常出现的频率无明显差异（p＞0.05）；在异常q波和室上性心律失常出现频率及心电图评分方面，gos＞3的组别明显低于对照组（p＜0.05，p＜0.001）；③心电图评分是sah患者预后最显著影响的变量（p=0.002，or=0.010，95%的可信区间0.001~0.173）。结论心电图评分作为一种新型、简便的半定量方法，能有效的预测蛛网膜下腔出血病人的预后。关键词：心电图；预后；评分；蛛网膜下腔出血
