After bradykinin effected on C6 rats, the activity of HSF1 trimer and protein expression of HSP70 were gradually increased and then reached the peak at 5 min and 10 min (maximum levels were 2~3-fold greater than control group, P.01, compared with control group).

肿瘤组织内HSF1蛋白三聚体活性和HSP70蛋白的表达逐渐增加，且分别于处理后的5 min和30 min时达高峰（P.01，与对照组相比），最大值为对照组的2~3倍。

For obtaining the aneuploid in rice,the primary trisomic from triplo-1 to triplo-12 and the aneuploid derived from 1992~1995.From the offspringe of triplo-10, a primary trisomic of chromosome 10 of this variety,an isotetrasomic triplo-10-1 was obtained.

在水稻上，为了获得这类遗传材料，从中籼3037同源三倍体后代产生的非整倍体中，在筛选初级三体的同时，进行了等臂染色体变异材料的筛选。

Suspects of DS and 26 cases of fetal amniocytes come from pregnant woman with high risk of DS were undertook to analysis 10 STR loci simultaneously by PAGE and silver staining or automated fluorescent laser activated detector sequencer (ABI310). 6 suspects of DS were determined as DS by trisomic triallelic with a ratio of 1: 1: 1 and the other STR loci show nonnal diallelic pattern with a ratio of 1: 1 or homozygous with two alleles of the same size. The other one suspect determined as DS by 7 STR marker showing trisomic diallelic band or peak.

将10个STR位点的PCR产物用聚丙烯铣胺凝胶电泳和银染法或基因片段扫描法进行检测，结果从23例可疑患者中发现7例DS患者，其中6例均出现三条带图谱，1例虽未发现3条带图谱，但除纯合子外其余位点均表现为双倍剂量（2：1）的2条带图谱。26例胎儿羊水细胞STR基因型均表现为正常2条带图谱（1：1），表明为非DS胎儿。

Hexavalent chromium is the most toxic form, the toxicity of trivalent chromium than 100 times.

六价铬是毒性最大的形态，其毒性比三价铬高100倍。

Third, nearly seven times the service life of halogen lamps; As already mentioned, halogen light-emitting principle is caused by a tungsten filament heating, while the tungsten filament in the long term there will definitely be blown under high temperature damage, so they are the life of 200 ~ 300 hours or so.

第三，近7倍于卤素灯的使用寿命；前面已经讲到，卤素灯的发光原理是由钨丝发热所致，而钨丝在长久的高温下难保不烧断损坏，所以它们的使用寿命只有200~300个小时左右。

The software is also useful for genotype analysis of trios and to show regions of potential uniparental disomy.

该软件对三重基因型的分析及显示潜在的单亲二倍体的区域也是有用的。

The result shows that' this method can effectively optimize the data-visiting pattern of filter wave processing so as to raise the speed of two-dimensional and three-dimentional picture's filter wave processing.

结果表明，此方法能有效地优化滤波处理的数据访问模式，从而使二维和三维图像滤波处理速度提高3至7倍。

Of three different soil amendments, with 100 times of wood vinegar treatment with the way of sprinkling the root combination of spraying the leaf got the best effect in controlling early blight, measured as 33.33%.

三种物质中以木醋液100倍采用叶面处理+灌根处理，土壤微生物数量最多，对番茄早疫病的防治效果最好，达到33.33%。

Results showed that all the three sweet sorghum varieties contained plentiful sugar, which can provide enough carbon source for alcohol fermentation, however, total nitrogen and some mineral elements（Fe3＋）cannot meet the needs of alcohol fermentation. Activity of most microbes in stalk juice can be inhibited and the sugar can be maintained when the stalk juice was condensed to 4～5 times. Due to the reasons that the activity of acetous microbe or hydrolysis enzyme inside stalk juice can be maintained, ratio of reducing sugar to total sugar was increased with storage time at 55～60℃,0.15 MPa vacuum condensed condition, which can be beneficial for the purpose of alcohol fermentation.

结果表明，三个品种都含有丰富的糖分，可以为酵母菌发酵制取酒精提供良好的碳源，但总氮和某些矿物质元素（如：Fe3＋）不能满足酒精酵母的营养需要；甜高粱茎秆汁浓缩至4～5倍时，可以抑制汁液中大多数微生物的活动，使其中糖分不受损失；在试验设定的真空浓缩工艺条件下（55～60℃，0.15 MPa）甜高粱茎秆汁中产酸微生物或水解酶类仍保持活性，使得还原糖占总糖的比率随贮藏时间延长而升高，这有利于酒精发酵。
