Positive rate was relatively high, and the foreign gene could also maintain in testicular tissue for a long time, it could still be detected in the tissue in 7 months after being injected. However. Deferent results could be gained when the detection were made with different primers on different sites of the recombinant plasmid. This could be explained by transgene lost when the foreign gene recombinated and integrated in heterogenetic cell, or transgene degradated by cell nucleases.

然而，我们也看到，在后代检测中，利用不同的引物扩增重组质粒不同部位时，检测结果存在差异，转基因阳性率不同，这种差异说明当外源基因进入到异源细胞内，在重组整合时发生了外源基因丢失的现象，并由此导致外源基因的整合率下降，也可能是受细胞内核酸酶的作用，使得外源基因遭到降解。

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。

The results showed that(1)even though there were no significant gender differences increative thinking,neither in Chinese children nor in Germanchildren,and neither in supernormal children nor in normalchildren,the males were superior to the females in mentalfolding;( 2) there were significant gender differences inlearning motivation and technical problem comprehension andactivities in science.

The results showed that there were differences between adaption and regulation of different wheat varieties by prophyl dihydro jasmonate, so as to show diversity of gas exchange parameters, such as photosynthesis, water usage, etc. There was no evident difference between the reaction of two spring wheats (Jinchun1 and 1608) and the winter wheat (Xiaoyan 22) to PDJ. Different parameters of different wheat varieties had inequable reaction to different concentration of PDJ. Photosynthesis rate, water use efficiency and stomatal limiting value were enhanced when PDJ concentration reached a high degree. At the same time, leaf transpiration rate and stomatal conductance decreased. Therefore, wheat could maintain normal physiological activities while environmental conditions were changed.

结果发现，面对类似激素双氢茉莉酸丙酯调控下的不同品种小麦适应与调节存在差异，从而导致光合和水分利用等气体交换参数的表现也存在差异；两种春小麦（金春1号、l608）和一种冬小麦（小偃22）之间对PDJ的反应没有明显的冬春性间的差别；对不同品种、不同参数，PDJ起到作用的浓度不同，但无论如何PDJ都有相同的作用，当这种激素达到一定的浓度后，就会增强小麦的光合速率和水分利用率，增加气孔限制值，降低叶片的蒸腾速率和气孔导度，从而在外界条件变化时保持体内水分、延缓气孔关闭，维持体内正常的生理活动。
