NGF had obvious cytotoxicity on these cell lines ,which shows to be dose-dependent, especially for MGC-803 and BEL-7404 ,their IC_(50) value at the 24~ hours are 49.9mg/L and 55.46mg/L ; Main features of apoptosis under fluorescent microscope include reduction in volume,nuclear chromatin condensation, intensification under jacinth fluorescence; The early apoptosis rate of pristine cells which detected by FCM increases with NGF dose increasing.

2NGF对4种人肿瘤细胞均有细胞毒性作用，且呈剂量依赖关系，尤其是对MGC-803和BEL-7404的抑制作用更强，作用24h的IC50值分别为49.9mg/L和55.46mg/L，荧光显微镜下可观察到MGC-803凋亡细胞的主要特点为：细胞体积缩小，染色质固缩，橘红色荧光增强；流式细胞仪检测到MGC-803细胞的早期凋亡率随NGF浓度的增高而增加，各浓度组与对照组的早期细胞凋亡率比较有明显差异(P＜0.01)。

Continuous culture of immobilized Acidithiobacillus ferrooxidans can be used to remove H2S and SO2. In order to reduce the negative effect of jarosite which formed during the oxidation of Fe(superscript 2+) by immobilized cells, the changing of initial pH and the ingredient in 9K medium were tried.

该固定化细胞的连续培养技术可以用于处理H2S、SO2，为了减少固定化细胞培养过程中带来许多不利效应的黄铁矾沉淀[NH4Fe3(SO4)26]，采取了改变初始pH值和目前普遍采用的9K培养基中的(NH4)2SO4浓度，K2HPO4浓度三种方法。

In order to reduce the negative effect of jarosite which formed during the oxidation of Fe2+ by immobilized cells, the changing of initial pH and the ingredient in 9K medium were tried. The results showed: among the three methods, decreasing the concentration (NH4)2SO4 was more feasible than two others.

Ethanol production by fed-batch fermentation was investigated and the maximum ethanol concentration of 94.81 g/L, equivalent to 81.54% of its theoretical value, was reached with final Jerusalem artichoke flour of 300 g/L in a 5 L jar fermenter.

在此基础上，对菊芋粉补料发酵进行了试验，补料至菊芋粉终浓度为300 g/L，发酵终点乙醇浓度为94.81 g/L，理论转化率为81.54%。

The results implied that cell karyokinesis could be promoted at low concentration and be restrained at high concentration.

在一定低浓度条件下，蚕豆根尖细胞有丝分裂指数增高，高浓度下有丝分裂指数降低，意味着低浓度可促进细胞有丝分裂，高浓度则会抑制细胞有丝分裂。

At 400μg/mL, the micronucleus ratio was 36.0l‰ and karyokinesis index was only 1.90%. The multi-nucleolus ratio was significantly enhanced at the concentration 200~400μg/mL, and the ratio at 400μg/mL was 26.10‰.
