Study on the activity of PAL、POD and SOD in the corn after inoculated pathogen showed that there were big differences between resistance and susceptible materials. The changs were more stabilization in resistance materials than in susceptible materials. There is a wave crest of activities in resistance materials, but no activity wave crest in the susceptible.

通过对抗、感品种接种病原菌后，其苯丙氨酸解氨酶、过氧化物酶和超氧化物歧化酶活性变化的研究表明，抗、感材料之间的变化大不相同，抗病材料中的各种酶活性变化都比较稳定，并且有活性波峰；而感病材料中各种酶活性变化都比较大，并且没有活性波峰。

A similar initiator, Et_2Zn/-Sparteine, yielded polys with threo-diisotactic -rich structure in the main chain, indicative of strongly asymmetric inducation in this system. In this case, no polymeric complexes in-site formed because of the intensive coordination between sparteine and Zn ions.The binary initiating system composed of Et_2Zn and n-BuLi combined the advantages of both metal alkyls, which gave the polymers with higher molecular weights and moderate optical activity ~(25_D =-97.1°～+24.3°.

Et_2Zn／n-BuLi二元引发体系综合了两种金属烷基化物的优点，得到了分子量相对较高(M_n=1.4x10~3～4.9×10~3)且含有手性超分子结构的光学活性聚合物；聚合物中锌含量的微小变化可引起聚合物光学活性明显改变，超分子手性与聚合物侧基的绝对构型存在关联。

The results showed that the mammary tissue cultured in superfusion system could keep normal tissue activity and ultrastructure within 24-72 h in DMEM plus 10 % calf serum, while mammary tissue stationary culture could keep normal tissue activity and ultrastructure within

结果表明：以1 mL/h 的速度灌流培养的奶牛乳腺组织在DMEM+ 10 %小牛血清培养基中24~72 h 内保持良好的组织活性和超微结构，贴壁培养的奶牛乳腺组织在DMEM+ 10%小牛血清的培养基中48~108 h 内保持良好的组织活性和超微结构，两种培养方法各有优缺点。

The RhoA oncogene , have been revealed in recent years, are closely related to various malignant tumours. RhoA, belonging to Rho family, is one member of the ras superfamily, whose encoding production, namely RhoA protein, pertaining to micromolecular mass GTP conjugated protein family, in GTP conjunctive active form and GDP conjunctive unreactive form. It exist in the latter form in normal cells and the switch of the two forms enables them to educe functions, paralleling"molecular switch", the diminutive G protein in activated state being able to activate the wink dromo-iter to work functions, which is in the resemblance of process during which the Ras genic mutation induces its continous activations.

RhoA是近年来新发现的与多种恶性肿瘤密切相关的癌基因，RhoA属于Rho亚家族，是ras基因超家族的一员，其编码产物RhoA蛋白属于小分子量GTP结合蛋白族，分为GTP结合的活性型和GDP结合的非活性型两类，在正常细胞内以GDP结合的非活性型存在，两种活性形式之间的转换使他们能够发挥一种类似"分子开关"的作用，活性态的小G蛋白能激活下游的信号传导通路，行使其功能。

In addition, a metabolic inhibitor, actinomycin D has no effect on enzymatic activities of caspase-1/ICE-like and caspase-3/CPP-32/like proteases during Fas-mediated CD4〓T cell apoptosis. These results indicate that the appearance of caspase-1/ICE-like and caspase-3/CPP32-1ike proteases activities is a post-translational activation of these proteases. It is likely these caspases constituently express in a inactive form in the cytosol of CD4〓T lymphocytes. Once the rest SEB-responsive CD4〓T cells are restimulted, those inactive caspases such as caspase-1/ICE-like and caspase-3/CPP32-1ike proteases are sequentially cleaved to become active forms, and the apoptotic signal is transducted to downstream signaling molecules, Finally leads to CD4〓T cells apoptosis.

另外，通过代谢抑制剂放线菌素D对超抗原SEB诱导静息SEB应答〓细胞凋亡过程中Caspase成员酶活性变化的研究表明Caspase-1／ICE样，Caspase-3／CPP32样胱氨蛋白酶并非新合成的信号分子，很可能以无活性方式组成性表达于静息SEB应答〓细胞胞浆，在超抗原SEB再次刺激诱导〓细胞凋亡早期，先后顺序活化，借以传递凋亡信号到下游信号分子，诱导〓细胞凋亡。

Their catalytic activities in the condensation reaction of cyclohexanone with ethanediol were studied.The results showed that the catalytic activity of SO_4~(2-)/ZrO_2-Ce_2O_3 in the condensation reaction ...

实验表明：(1)SO42-/ZrO2-Ce2O3在缩合反应中的催化活性比SO42-/ZrO2和SO42-/ZrO2要强；(2)引入适当数量的Ce2O3使得固体超强酸的酸强度增大；(3)当固体超强酸SO42-/ZrO2-Ce2O3的制备条件为焙烧温度550℃、焙烧时间4h、Ce2O3质量与ZrO2质量比2%时，酸对缩合反应的催化活性最高。

Synchronous fluorescence showed that the addition of POM could enhance the fluorescence intensity of CV, which was explained in terms of the hindrance of the formation of the nonfluorescent twisted intramolecular charge transfer states of CV by the assembled POM-CV system, and the surfactant CTAB could enhance the luminescence by coordinated assembly.

具有同样Keggin结构的4种稀土杂多阴离子与结晶紫的作用总体一致，稀土元素不同体系的光活性会表现出一定的差异。实验证实，阳离子表面活性剂CTAB的存在会进一步增强体系的发光活性。三者协同作用，形成了更稳定的杂多阴离子－CV-CTAB三元超分子体系，而β-CD的存在对稀土杂多酸盐与结晶紫的超分子体系稳定不利。

The results show that compared with the uninoculated pear fruit, the PPO activity of the pear fruit inoculated by the pathogen markedly increase in 48 hours after the inoculating treatment, the PAL activity is on the rise during the 120 hours after inoculation, POD and CAT activities reach a peak at 72h after inoculation, and the SOD activity of the inoculated treatment is also obviously higher than that of the contrast, which suggests that those enzymes are closely-related to pear fruit against Botryosphaeria berengriana f.sp.

结果表明：鸭梨果实中多酚氧化酶活性在接种轮纹病菌48 h内显著高于对照，苯丙氨酸解胺酶活性在接种120 h内一直呈上升趋势，过氧化物酶和过氧化氢酶活性在接种后72 h出现活性高峰，超氧化物歧化酶活性在接种后120 h内也显著高于对照，说明这些酶对鸭梨果实抵抗轮纹病密切相关。
