NADPH oxidase inhibitor, diphenylene iodonium chloride (DPI, 10 μmol/L), abolished histamine-stimulated calcium oscillations both in normoxic and posthypoxic PAECs.(3) Xanthine oxidase inhibitor, oxypurinol (100 μmol/L), did not affect the calcium oscillation kequency in normoxic PAECs. However, it significantly decreased the elevation of calcium oscillation frequency in posthypoxic PAECs.

黄嘌呤氧化酶抑制剂，别嘌呤醇(oxypurinol，100 μmol/L)能显著降低组胺刺激的缺氧后肺动脉内皮细胞升高的钙振荡频率，但降低后的钙振荡频率仍高于常氧组，别嘌呤醇对组胺刺激的常氧组肺动脉内皮细胞钙振荡频率无显著影响。

Studies of the binding of metal to calmodulin and the subsequent binding of metal-calmodulin complexes to the target protein/peptide revealed that the La-content calmodulin complexes to its target exhibit similar affinity with the Ca-calmodulin complexes.However, there were substle differences in protein conformation as well as the kinetical properties between the two kinds of metal-calmodulin complexes, suggesting Ln could produce cellular effects via the Ca/calmodulin signaling systems.

稀土离子和钙调蛋白的结合以及后续和靶酶的结合，在热力学上与钙离子激活蛋白具有相同的亲合力，但在动力学性质上以及细微构象上明显不同，显示稀土离子可通过细胞钙相关信号系统产生特别的生物效应。

We study the express of heparinase,matrix metalloproteinase MMP-2,MMP-14 and cadherin in the gastric cancer tissue and perigastric normal mucosal tissue,and make a statistics analysis between heparinase, matrix metalloproteinase MMP-2,MMP-14,E-cadherin and gastric cancer biological behavior.We hope to knom the possibility that heparinase,matrix metalloproteinase MMP-2,MMP-14,E-cadherin are regared as clinical screen index of the gastric cancer recrudescence or metastasis.

本文就肝素酶、基质金属蛋白酶MMP-2、MMP-14、钙粘蛋白在胃癌组织及胃周正常粘膜的表达进行了研究，并就肝素酶、基质金属蛋白酶MMP-2、MMP-14、钙粘蛋白与胃癌的生物学行为进行了统计学分析，以期了解肝素酶、基质金属蛋白酶MMP-2、MMP-14、钙粘蛋白作为胃癌复发或转移的临床筛选指标的可能性。

Whole-cellpatch-clamp technology demonstrated that VDPG (1g/L) had notsignificant effects on the delayed-rectified K~+ current, TTX-sensitive Na~+ current and high-voltage-activated Ca~(2+) current of rat dorsalroot ganglion cells. The fast transiet K~+ current of cottonbollworm dorsal DUM cells, the fast transiet K~+ current, Na~+ current andhigh-voltage-activated Ca~(2+) current of Periplaneta Americana dorsalunpaired median cells were also not significantly affected byVDPG at the same concentration. However, VDPG had significant effecton the fast transiet K~+ current of Pieris rapae. The VES had not significanteffects on the high-voltage-activated and low-voltage-activated Ca~(2+)current of rat DRG cells.

膜片钳电生理实验显示1g／L毒囊粗毒对蜚蠊DUM神经元的快瞬时钾电流、钠电流、高电压激活的钙电流，对棉铃虫快瞬时钾电流和大鼠DRG细胞延迟整流钾电流、TTX-S型钠电流、高电压激活的钙电流均无明显作用，却对菜青虫快瞬时钾电流有明显作用；电刺激粗毒对大鼠DRG细胞低电压和高电压激活的钙通道无明显作用。

As a result of recent world-widediscussions on the possible harmfulness of sulphites, theJoint FAO/WHO Expert Committee on Food Additives has assessed the intake of sulphur dioxide andrelated compounds, suchas calcium, potassium andsodium hydrogen sulphite; calcium, potassium and sodiummetabisulphite; calcium, potassium and sodium sulphite;and sodium thiosulphate.

However, in recent yean, the landscape come to be dried up. Blacken, sanded, which have seriously affected the sight's admiring value. It is Very important to take the landscape measures and control human activity to research the rules and influencing factors of travertine. It will be good to society, economy.

但近年来黄龙钙华出现了干涸、变黑、沙化等现象，严重影响了景观的可观赏性：深入研究该区的钙华演变规律和影响因素，对于采取科学的保护措施，控制人为活动时钙华资源的不利影响将其有重要作用。

That if the process can produce much liquid phase during the sintering, and which can become into completely-crystal needle-shap or aborization or bar-shap calcium ferrite instead of glass in the cooling process; if the magnetite is interweaved by the caking into the melting corrosion structure, the granular structure or the eutectic structure instead of exiling in the massive isolation; if the mount of the poreis is little, and uniformitly distributing; if the grain is little; if the organizational structure is symmetrical, all of which can improve the quality of the sintering.

另外还归纳出有利于强度提高的工艺参数和操作制度。分析工业试验和水钢现行生产的矿物组成、结构表明，水钢烧结矿以他形晶磁铁矿为主，铁酸钙为主要的粘结相，多形成熔蚀结构、粒状结构和共晶结构，强度较高；而在台车边缘和表层，由于存在较严重边缘效应和点火温度较低，使该区域的烧结矿组织结构疏松，局部呈蜂窝状或薄壁大孔状，铁酸钙较少而硅酸二钙和玻璃质较多，形成骸晶状结构和磁铁矿连晶，强度较低，致使返矿升高。
