与...相比

To expert ears, the music on compressed files sounds more crackly, thinner and tinnier than on CDs, and especially on vinyl.

在专家的耳朵里，压缩过的音乐听起来比较有杂音也比较不厚实，与CD相比已是如此，更何况与黑胶唱片相比。

To evaluate the efficacy of the recombinant fowlpox virus vaccine against the heterotype IBV, the chickens were challenged with the homotype IBV LX4 strain and the heterotype IBV LTJ95I strain after three weeks post vaccination. Antibodies against IBV were detected in vaccinated chickens one week post inoculation. The CD4+ T-lymphocytes in the peripheral blood increased rapidly in all groups challenged with IBV, except for the vaccinated group challenged by heterotype strain and the low level of CD4+ T-lymphocytes remained until end of the experiment. In all the groups, a high level of CD8+ T-lymphocytes only was observed in the vaccinated group after challenging with IBVhomotype strain. The morbidity and the mortality of this group were 21.43 % and 0 %, respectively, which showed significant difference with other groups. In addition, the lesions of chickens and virus shedding were less in the vaccinated group challenged by IBV homotype strain comparing with other groups, but there was no difference for the average body weight of chickens in all groups.

结果显示，重组疫苗接种1周后，免疫鸡产生抗IBV的抗体；而且外周血中CD4+和CD8+ T淋巴细胞的含量略高于非免疫对照组；攻毒后，异源强毒株攻毒的免疫组CD4+ T淋巴细胞呈下降趋势，并且该组低水平CD4+的状态一直持续到试验结束，而其他组CD4+ T淋巴细胞均迅速上升，峰值达到14.5 %；同源强毒株攻毒的免疫组CD8+ T淋巴细胞呈高水平的表达，而其他组攻毒后均无明显变化；保护率结果显示，同源强毒株攻毒免疫组的发病率和死亡率为21.43 %和0 %，与其他各组相比均有显著差异；另外同源强毒株攻毒的免疫组病理损伤与异源强毒株攻毒的试验组相比明显减轻，其排毒时间和排毒量也均有所减少；强毒攻毒后所有试验组体重无显著差异。

It was found by means of protein fluorescence detection that the number of MAP-2 masculine neurone in the hippocamp of AD rat in model group and zinc reinforce post-AD group decreased distinctly. There was not distinct difference in the MAP-2 expression and the number of MAP-2 masculine neurone between normal group and zinc reinforce pro-AD group.

Results: In acute experiment, there was no significant difference of body weight or organ indexes between the normal control and arsenic poisoning groups ; while the CH50 level, lymphocyte accruing rate, phagocytosis rate and macrophagocyte index in arsenic poisoning group were significantly lower (P.05 or P.01) than those in normal group. There was no significant difference of body weight or organ index between arsenic poisoning group and EXD (10 g) treated arsenic poisoning group, while CH50, lymphocyte accruing rate, phagocytosis rate, and mavrophocyte index were significantly higher in EXD (10 g) treated arsenic poisoning group than those in arsenic poisoning group (P.05 or P.01). In EXD (5 g) treated arsenic poisoning group, results of all the tested indexes were the same as those of arsenic poisoning group.

But in 24h experiment group, the decreases of the indexes are not statistically significant. Conclusion Early application of rhEPO could lessen the lesion of neuromotor function and secondary pathology change. The protection is partially due to the reduction of expression of Caspase-3 and neural cell apoptosis.
