下降

The activities of both SOD and POD of leaves and root system were en hanced during the early stage of high temperature treatment, and then dropped as the time went on.

在高温处理过程中，根系和叶片SOD及POD酶活性的变化均表现为先升高而后下降的趋势，但叶片SOD和POD活性下降较早，其下降幅度亦大于根系，表明地上部受高温影响较大。

The study on the electrical property shows that its dielectric property decreases with the slowly increase of frequency in dry state; in hygrometric state (52.9%), the dielectric property grows obviously and declines swiftly with the increase of frequency; and it tends to be stable when the frequency is over 10^4Hz. The specific resistance decreases linearly with the increase of the frequency. The results indicate that the electric properties of the hot press moulded wheat gluten are subject to the compaction rate of the material structure.

对小麦麸质模压板的电性能研究表明，干态下其介电性能随电场频率增加而下降，但变化小；湿态下其介电性能明显提高，且随频率增加迅速下降，超过10^4Hz后区域变化趋于稳定；热压小麦麸质材料的电阻率随频率的增加呈直线下降；小麦麸质热压材料的电性能主要决定于材料结构的密实程度。

Eighty percent of the potassium taken up by cotton was from nonexchangeable potassium of the soil.Both the pot and the field experiment showed a same result that the content of soil nonexchangeable potassium will no longer decrease when it reached a certain level,while nonextractable potassium with 1 mol/L HNO3 will continue to decline.

棉花吸收的钾素中有80%来自于土壤非交换性钾，盆栽生物耗竭与连续种植10年棉花的田间土壤，具有相同的结果，土壤交换性钾在下降到一定程度后不再下降，而1mol/LHNO3不能提取的钾一直在下降。

The study on the photoinhibiton of Pistachio shows: the exposure of Pistacia vera seedlings to high irradiance induced lowering of apparent quantum yield , maximal fluorescence , minimal fluorescence , variable fluorescence , photochemical efficiency of PS Ⅱ, and photochemical quenching , but raising the Non-photochemical quenching , this indicates that high irradiance reduces the quantities of oxidized Q〓, which depresses the ability of electron transport from Q〓 to Q〓, and lowers the electron transport rate and the photosynthesis rate.

对&光抑制&研究表明，强光照射后，叶片表观量子效率、最大荧光、初始荧光、可变荧光、光化学效率、和光化学猝灭系数下降，而qN升高，说明强光处理降低了Q〓的氧化态数量，使Q〓→Q〓传递电子的能力下降，进而导致了电子传递速率和光合速率的下降。

Results:The following phenomena were observed:the Ph, PaO2 of the model rabbits descended sharply, the PaCO2 increased lightly, the HR slowed down obviously, but the BR increased, the SBP and DBP of the model rabbits descended markedly, and the PS content decreased dramatically. The pneumonic pathology changes showed pneumorrhagia, atelectasis, shrink of alveolus and pulmonary hyaline membrane. The above results indicated that it accorded with the standard of I-type of acute respiratory distress syndrome.

The reduction of the number of propagative floweret resulted in decrease of the differentiae floweret, but no decrease of the percentage of floweret deterioration.

而可孕小花数下降并非发育小花退化百分率下降所致，而是发育小花数下降造成。

The activity of Carboxymethylcellulase rose and peaked on September 8, and then decreased; the activity of Pectinmethylesterase decreased before September 18 ( early and middle stage of maturity), and then rose to the peak value on September 28, and then decreased dramatically; the activity of Polygalacturonasewas lower before September 18, while its change was same as activity of PE after September 18; cellulose and protopectin of granulated juicy sac were higher than those of non –granulated juicy sac respectively, but activity of Cx, activity of PE and activity of PG of granulated juicy sac were lower than of non-granulated juicy sac respectively.

纤维素酶活性在成熟期间随果实成熟上升，到9月8日出现活性高峰后下降；果胶甲酯酶活性在成熟阶段前中期(9月18日)PE活性呈下降趋势，在9月28日出现PE活性高峰后快速下降，汁胞PG前中期活性较低，9月18日后的变化趋势和PE活性的变化一致。粒化汁胞的纤维素，原果胶含量均高于未粒化汁胞；它的CX活性、PE活性，PG活性低于未粒化汁胞。

In the beginning, at the situation of high blood volume, if the blood glucose sufficient, the erythrocytic function of making ATP by glucose is normal, the free radical and the anti-free radical of the rat basicly keep balanced, erythrocytic deforming ability is not influenced greatly; while the erythrocytic function of making ATP degenerates in sport iron deficient erythrocyte formation and hemolysis, especially the former; and the vitalities of anti-free radical reduce greatly in blood, liver and Erythrocyte, the reducement of liver SOD vitality in the former and erythrocyte SOD vitality in the latter are more obvious, and the total blood SOD amounts reduce identically; The erythrocytic deforming ability reduces greatly too, but there is no obvious difference between the two groups, but the tendency of the inner-mechanism may be different needing to researching deeply later.

而长期递增的大负荷运动造成缺铁性红细胞生成或溶血发生时，红细胞利用葡萄糖制造ATP的功能下降，且前者下降更为明显；抗氧自由基活性均显著降低，HA组肝脏SOD活力和IDA组红细胞SOD活力降低更为明显，而二者血液总SOD降低一致；红细胞变形能力均显著下降，但内在机制的倾向性可能有所不同，建议进一步深入研究机理。

Egr-1 mRNA and Egr-1 protein hadn't been found in the normal vein. The expressions of Egr-1 mRNA and Egr-1 protein had biphasic changes. By reverse transcription-PCR and in situ hybridization, we found that the level of Egr-1 mRNA rose at 1 hour after graft, the expression of Egr-1 mRNA was (35±7)%. Decline at hour 6, 24 and day 3, the positive rates of Egr-1 mRNA were (8±2)%,(8±6)% and (8±4)% respectively. Reincrease at day 7, a peak at day 28, the positive rate of Egr-1 mRNA was (45±6)%(compared with other phase, P＜0.01). At day 42, the expression of Egr-1 mRNA declined again. Immunohistochemical staining and Western blot revealed Egr-1 protein had expressed at hour 2 early phase, the expression of Egr-1 protein was (30±5)%, and until to hour 6. The level of Egr-1 protein was decrease at hour 24 and day 3, the positive rates were (7±3)% and (7±8)% respectively.

结果 自体静脉移植后，Egr-1 mRNA和Egr-1蛋白的表达呈双相变化，即移植后1 h， Egr-1 mRNA表达迅速升高，阳性率为（35±7）%，6 h、24 h及3 d时下降到较低水平，阳性率分别为（8±2）%、（8±6）%和（8±4）％，7 d时又再升高，28 d时达高峰，阳性率为（45±6）%，此与其余各时点比较差异均有统计学意义（P＜0.01），42 d时，Egr-1 mRNA的表达再次下降；移植早期（2 h）即有Egr-1蛋白的表达，阳性率为（30±5）%，并持续至6 h，24 h～3 d表达下降到较低水平，阳性率分别为（7±3）%和（7±8）%，7 d时又再升高，至移植后28 d，Egr-1蛋白的表达阳性率达到高峰，为（40±9）%，此与其余各时点比较差异有统计学意义（P＜0.01）。

Transcriptional activity of ACL recombinants normalized by Renilla was significant difference with pGL3-Basic expect for construct -27 and -15 (P＜0.01). Construct -919 contains highest activity. 3 times reduction of transcriptional activity from-919 to -679bp indicated that negative regulation factors located probably in this region. The activity started on construct -73 suggested the basal promoter activity was located within the -73 to +77bp region; Transcriptional activity of IDHβrecombinants was not significantly different between the recombinant -58 and pGL3-Basic. The activity started on construct -82, decreasing with the length of the fragment up to -164 in despite of a bit of fluctuation, and kept increasing from construct -164 up to -279. Thus, the basal promoter activity was located within the -82 to +16bp region, whereas the upstream 197bp conferred maximal transcriptional activity.

采用5'端缺失策略，结合启动子预测结果，分别构建了8个ACL基因和19个IDH3β基因启动子区重组子，将其转染猪PK15细胞系，并利用荧光素酶双报告基因系统检测了它们的活性，结果表明：在所构建的猪ACL基因5侧翼序列的8个重组子中，除pGL-ACL27和pGL-ACL15外，其它重组子的荧光素酶活性与阴性对照均达到极显著水平(P＜0.01)，表明它们均具有启动子活性，pGL-ACL919活性最强，到pGL-ACL679活性下降了将近3倍，说明从-919bp到-679bp区域可能存在负的调控位点，从pGL-ACL621到pGL-ACL73活性有小幅度下降，到pGL-ACL27活性降到与阴性对照水平无显著差异，表明维持该启动子的基本活性区域位于-73bp到+77bp之间；IDH3β基因启动子活性开始于pGL-IB82，然后虽然有些波动，但是活性一直下降直到-164bp处，之后活性又开始升高，直到-279bp处活性达到最高，这些表明维持该启动子的基本活性区域位于-82bp到+16bp之间，从-82到-279之间的179bp区域具有最高的启动子活性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
