The outward rectifier K+ current current was the dominant K+ current in the whole cell currents in Deiters' cells. In the presence of 200μ M linopirdine, the Ik current was not significantly effected. Our findings demonstrated that the KCNQ heteromeric or homomeric potassium channel may be the molecular basis for the peak outward K+ current and testified that the inward IKn current is mediated by KCNQ potassium channel.

在细胞外液中，加入100 μmol/L利诺吡啶后，OHCs中的四乙基二乙胺敏感的钾电流峰电流成分被抑制，稳态电流幅值减小，且电流的失活时间常数明显延长；在细胞外液中加入100 μmol/L和200 μmol/L利诺吡啶后，OHCs的内向性钾电流IKn被完全抑制；而细胞外液中利诺吡啶终浓度为200 μmol/L 时，Deiters细胞的外向整流性钾电流幅值无明显变化。

There were no nick infection, chorioamnionitis and other complications. Eight/sixteen fetal lambs were undergone intro-utero cardiac intervention. The values of body weight and Hct of lambs which were executed. pre-term and full-term delived were (1.77±0.14) kg vs.(2.15±0.23) kg vs.(2.41±0.19) kg and 29%-33% vs. 27%-35% vs. 37%-41%. In autopsy, hydropericardium was found in 4/8 with 1-2.5 mL and 1/8 with 5 mL. Besides 1/8 with interventricular septum centesis injury, there was no centesis damage to endocardium, valve, chordae tendineae, papillary muscles and aortic tunica intima.

The mixture of triethanolamine oleate and Tween80 or NP-10 can make the O/W emulsion particle smaller and more uniform than other surfactants, and increase thewettability and the stability of O/W emulsion. The type, hydrophile lipophile balance value,content and their mixture of surfactant have great influence on the emulsion droplet diameter.
