Results Lorcainide at concentration of 0.62mg/L,1.25mg/L and 2.50mg/L had a tendency of decreasing the incidence of arrhythmia during ischemia (P＞0.05),and at 1.25mg/L and 2.50mg/L significantly decreased incidence of arrhythmia during early reperfusion (P＜0.05).Its antiarrhythmic effect was accompanied with elevation of subendocardial threshold,significant abbreviation of action potential duratin in subendocardium and subepicardium,and complete or partly delay of transmural conduction time of pulses.

结果 劳卡胺分别在0.62mg/L、1.25mg/L及2.50mg/L剂量时使缺血性心律失常发生率轻度降低(P＞0.05)，后2种剂量使再灌注早期心律失常发生率明显降低(P＜0.05)；降低心律失常发生率同时可提高心内膜下心室肌兴奋阈，延长心内、外膜下心室肌细胞动作电位时程，延迟或部分延迟冲动跨壁传导时间。

In this thesis, the concentration of graphite powder in the liquid nickel sulfamate and current density are chosen as parameters for composite electrodeposition of nickel and graphite powder.

To test the hypothesis, neontal rat cadiomyocytes Treat with heat shock(HS,42℃,2h) to induce the expression of HSP70,then teated with 0.5mmol/L H2O2. We first found H2O2 can reduced cadiomyocytes apoptosis and HSP70 only over-expression in the HS group, other two group only express HSP70 a little in the test of expression of HSP70.Then we tested the concentration of Ca2+, the [Ca2+ ] of CON was 192.224+6.654, the [Ca2+ ] of H2O2 group was 290.6918+8.922and the [Ca2+]of HS group was 214.2633+4.484.To further determine how HSP70 repaired the Ca2+ homestasis, we measured calcium transient of each group.

实验中应用MTT和流式细胞技术检测细胞的凋亡，发现损伤组的存活率明显低于其他2组，热休克组(Heat shock group，HS group)细胞存活率略低于正常组细胞；免疫组化结果表明只有在HS组才检测到阳性反应，即是HSP70的表达，其他2组均为弱阳性结果；应用离子成像技术对细胞内钙离子浓度进行测定，发现损伤组290.6918+8.922明显高于正常组192.224+6.654和HS组214.2633+4.484，HS组细胞内的钙离子浓度略高于正常组；为了进一步探讨HSP70对于ROS引起的心肌凋亡过程中钙离子的调控机制，又对各组的心肌细胞进行了钙瞬变的测定。

Methods The cells of LLC-PK1,Hela,Caki-1,T24 and fibroblast were incubated on 96-w ell plate with addition of diffe-rent concentration of cystic fluid of ACDK and t hat of simple renal cyst. After 24 hours for reaction, MTT method was used to de termine and compare the proliferative activity of 5 cell lines.

将LLC-PK1， Hela， T24， Caki-1和成纤维细胞接种于96孔培养板中，经过24h培养，加入不同浓度的ACDK和单纯肾囊肿的囊内液作用24h，用MTT法测定培养细胞的增殖活性，比较两者之间对细胞增殖的抑制作用。

Effects of roast temperature, roast time, the amounts of sodium carbonate on decomposition of bastnaesite concentrate and effects of leaching temperature, leaching time, concentration of hydrochloric acid, the amounts of hydrochloric acid on leaching ratio of trivalent rare earth and tetravalent cerium was studied systematically.

系统地研究了焙烧温度、焙烧时间和碳酸钠的加入量对氟碳铈矿精矿焙烧分解的影响及浸出时间、浸出温度、盐酸浓度和盐酸用量对三价稀土和铈的浸出率的影响。

The type and concentration of thiophenic sulfur in gasoline and diesel fuel were determined separately by gas chromatography with a sulfur chemiluminescence detector.With activated carbon and 30％aqueous solution of H2O2 as catalyst and oxidant respectively, the experimental studies of oxidative desulfurization of gasoline and diesel were carried out.

采用气相色谱-硫化学发光检测器分析了汽油和柴油中噻吩类硫化物的分布及浓度；以活性炭作为催化剂，以30％过氧化氢溶液为氧化剂，在甲酸存在条件下考察了汽油和柴油中噻吩类硫化物催化氧化脱除的选择性，讨论了硫化物中硫原子电子密度对硫化物氧化选择性的影响。

Changes in IL-2/IL-2R system in 25 patients with thyrotoxic Graves disease and 20 eu-thyroids were investigated and compared with those of 15 normal controls. The thyrotoxic patients showed a high concentration of serum sIL-2R and a large amount of circulating IL-2R-α- cells but a decreased production of IL-2 by PBMC. However, these abnormalities had a tendency to become normal with improvement of the disease.

Graves病的发生是环境、遗传和免疫等多种因素综合作用的结果＊淋巴细胞的免疫调节异常是其中的一个重要原因，而白细胞介素-2（IL-2）及其受体在维持正常T细胞功能和兔疫调节方面发挥关键作用。

First, it contended that before the townish land using system was reformed, the conventional townish land using system hampered the concentration of rural and small town enterprises into town. However, after the system was reformed, because of the faultiness or disadvantage of the rural constructive land using system, the land price of enterprises location varied obviously which made an important influence on the location of rural and small town enterprises.

首先，从理论上提出在城镇土地使用制度改革前，传统的城镇土地使用制度阻碍了乡镇企业向城镇聚集；而认为在城镇土地使用制度改革后，农村集体建设土地使用制度的不完善或弊端所导致的，乡镇企业在农村选址的低土地成本与在城镇选址所带来的高土地成本二者之间的反差，对于现阶段乡镇企业是否在城镇布局有着重要的影响作用。
