Expression of Caspase-3 and bcl-2 protein In E20 cerebral cortex, the expression of cleaved Caspase-3 in the encephalocoele group are higher than that in control group, and the expression of bcl-2 in the encephalocoele group are lower than that in control group. These findings were consistent with the results of the western blot analysis in E14 Brain.

四、Western-blot检测E14、E20胎鼠大脑皮质中caspase-3、bcl-2蛋白的表达 1、用Western-blot方法检测不同组E20胎鼠大脑皮质中caspase-3、bcl-2蛋白表达水平，结果表明对照组、给药无畸形组、脊柱裂组胎鼠大脑皮质中caspase-3、bcl-2蛋白表达水平无明显改变，而脑膨出组胎鼠大脑皮质中caspase-3蛋白活化片段表达水平明显增加，bcl-2蛋白表达水平明显减少。

Expression of nNOS mRNA, eNOS mRNA and iNOS mRNA in the E 20 cerebral cortex: There were no obvious changes of expression of nNOS mRNA in ETU-injected and control groups. Expression of eNOS mRNA increased significantly in cerebral cortex of the encephalocoele group, And there were no obvious changes of expression of eNOS mRNA in cerebral cortex of the control group and the other ETU-injection groups.

六、不同组E20胎鼠大脑皮质中nNOS mRNA、eNOS mRNA和iNOS mRNA的表达 1、实时定量PCR检测发现对照组、给药无畸形组、脊柱裂组和脑膨出组E20胎鼠大脑皮质中nNOS mRNA表达无明显改变； 2、给药无畸形组、脊柱裂组和对照组胎鼠大脑皮质中eNOSmRNA表达无明显改变，而脑膨出组胎鼠大脑皮质中eNOS mRNA表达明显增多； 3、在各组未检测到iNOSmRNA表达。

MFPR is a safe and effective minimally invasive technique and it is also an effective salvage measure to multifetation.

多胎妊娠减胎术是一种安全、行之有效的微创技术，是多胎妊娠有效的补救措施，现已成为治疗多胎妊娠的主要手段。

Ovary superior or semi-inferior, 1-loculed, with 2-9 parietal placentas, rarely incompletely 2-9-celled by placentas protruding deeply into locule; ovules 2 or more on each placenta, orthotropous, anatropous, or hemi-anatropous; styles isomerous with placentas, free or partly to completely united, rarely absent, stigmas small or large, capitate to flattened and branched.

The pathological lesion rate caused by local pneumonia for the progeny swinery of the first-born sows was 3/%, and that for the second -born breeding sows was 11%, being 30% of the pathological lesion rate in the first-born sows, so the health level of more than the second-born breeding sows was more stable.

头胎母猪后代的地方性肺炎痛变率为31%，二胎以上母猪后代的地方性肺炎病变率是11%，为头胎母猪后代发病率的1/3，稳定了二胎以上母猪的健康水平。

The invention relates to a truck tire, comprising a tire cord fabric layer extended between the beads and provided with a cord thread, and a bead reinforcing layer arranged on each bead part.

一种载重轮胎包括：在胎圈之间延伸的具有帘线的胎体帘布层；以及设置在每个胎圈部分的胎圈补强层。

胎为黑色，底脚露胎，胎足如铁，器口薄釉处微露胎而泛紫色，称为&紫口铁足&，它与釉面的纹片相映衬托，显得古色古香，端庄典雅。

Half-sib mating was used and one boar and five gilts were raised in a mating pen. Numbers of born alive per litter produced by G1 sows at 1.0, 1.5 and 2.0 years of age were 1.82+2.47 (N=36), 3.02+2.56 (N=30) and 5.02+2.26 (N=34) piglets, respectively.

再进行1公5母的半同胞并栏配种，第一代种母猪的分娩年龄为1.0、1.5和2.0岁时，其每胎活仔数分别为1.82±2.47(36胎)、3.02±2.56(30胎)和5.02±2.26头(34胎)。

During the experiment, we choose Toyota Corona 1600cc as a test car and measure its maximal acceleration value by means of palm vibration noise analyzer, on conditions of the same tire pressure, speed, load, and road section and measure fuel consumption in a fixed speed and mileage. In addition, by using tire pressure gauge and infrared thermometer, measure after-driving tire pressure and tire temperature to make a comparative analysis. Finally, we use 185/60 R-14 Goodyear tire to measure tire sinkage in an empty car and a loaded car and obtain tire compression ratio to explain the difference of riding comfort and economical consideration of fuel consumption between nitrogen-filled tires and compressed air tires.

在实验时，采用丰田Corona 1600cc轿车，在相同的胎压、车速、负载、路段等条件下，透过掌上型振动噪音分析仪，撷取车辆行驶之最大峰值加速度；并在稳定车速及固定里程下量测汽油之消耗量，再以胎压表和红外线温度计，量取行驶后之胎压和胎温值来作比较分析，最后，再使用185/60 R-14 Goodyear 轮胎，在车上量测空车及负载下轮胎的下沉量，并求得轮胎的压缩率变化值，来说明氮气轮胎与一般压缩空气轮胎，在乘坐舒适性及燃油经济性上的差异原因。
