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.

Objective To observe the pathological changes and investigate the hepatocyte apoptosis relating with CYP2E1 in alcoholic liver diseaseof rat. Method the Model of Alcoholic liver Disease: Rats were randomly divided into model group(n=37)and control group(n=33). The dose of 40％ethanol was administerd at 8g/kg body weight by garage twice daily for 8 weeks in model group, and control group was received isovolume saline by gavage. End of 8th week, the activities of serum ALT and AST were detect by autobiochemistry instrument. The pathological changes of liver was observed under light microscope after HE staining, hepatocyte apoptosis was detected by the TUNEL method.

Based on these previous work, in this research, in order to explore the the molecular mechanism of enhanced tumor cell immunogenicity treated by elemene and mytomycin C compositely, we used murine Hca-F ascitic hepatic carcinoma ( high lymphatic metastasis substrain of H22) as an experimental model to compare the immunoprotective effects on Hca-F cells as well as the mechanism of the effects caused by HSP70-peptide complex purified from untreated tumor cells, EC-TCV and BCG; We studied the mechanism of increased tumor cell membrane HSP expression treated with elemene by the techniques of RT-PCR and immunoelectron microscopy; In order to deeply elucidate the antitumor effects and the molecular mechanism of elemene in increasing tumor cell immunogenicity we analyzed and compared the effects of elemene and heat shock on the gene expressions of tumor cell using gene expression profile chip.

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。

At histopathologic analysis, neuronal tumors are usually classified as pure neuronal cell tumors (gangliocytoma, Lhermitte-Duclos disease , central neurocytoma) and mixed neuronal-glial tumors (ganglioglioma, desmoplastic infantile ganglioglioma, dysembryoplastic neuroepithelial tumor, ganglioneuroma).
