The inward current in OHCs was totally inhibited after the superfusion of 100μmolIL and 200μmo1/L linopirdine respectively. The outward rectifier K(superscript +) current I(subscript K was the dominant K(superscript +) current in the whole cell currents in Deiters' cells. In the presence of 200μmol/L linopirdine, the current was not significantly affected.

在细胞外液中，加入100μmol/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100μmol/L利诺吡吮后，OHCs的内向性钾电流I被完全抑制；而细胞外液中利诺吡啶终浓度为200μmol/L时，Deiters 细胞的外向整流性钾电流幅值无明显变化。

After the application of 100μ M linopirdine to OHCs, the peak K+ current was reversibly blocked and the late K+ current was partly reduced. In addition, the decay time constant of the TEA-sensitive K+ current was prolonged in the presence of 100μ M linopirdine. The inward current in OHCs was totally inhibited after the superfusion of 100μ M and 200μ M linopirdine respectively.

结果发现，在正常细胞外液中，单离外毛细胞可记录到四乙基二乙胺敏感的外向性钾电流和静息膜电位附近激活的内向性钾电流（ the K+ current activated at negative potential， IKn）两种钾电流，而单离Deiters细胞中只记录到外向整流性钾电流。

The results are as follows:(1) Emodin enhances the electrical and contractive activities of the smooth muscle cells in guinea pig taenia coli....
