The rate of inhib ition of treatment iv - vi was higher than treatment i - iii . it is suggested that the three biotransformation enzymes may be directly or indirectly affected by the tested chemicals 三哇磷处理对肝脏酷酶活性在供试浓度范围和时间内，均有抑制作用， 96h时的抑制率在54 . 4一62 ， 5 %之间。
Results showed the ration of oil inhibitory on alfalfa seed germination was correlated linear - exponent with soil diesel oil densities , and yellow leaf and drying up was appeared after sprouting in high density dealing group 结果表明，紫花苜蓿种子发芽抑制率与土壤柴油污染浓度明显指数线性相关，而且发芽之后高浓度处理组幼苗出现黄叶和干枯现象。
Results : both etoac and n - buoh extraction on tumefaction ; when there is equal quantity of tannins , the inhibition degree is etoac > n - buoh > tea polyphenols ; the best inhibition on tumefaction of etoac is 22 . 39 % 结果：乙酸乙酯层与正丁醇层均有抑制肿胀作用；鞣质含量相同时，抑制肿胀程度强弱分别为乙酸乙酯层茶多酚正丁醇层；乙酸乙酯层最大抑制率为22 . 39 % 。
The ic50 of the active agent purified by carbon column is 0 . 525 mg / ml , which is better than that of acarbose ( ic5o = 0 . 9mg / ml ) . the zymosis juice of w - 20 can greatly decrease hyperglycemia level of mice by alloxan in glucose tolerance test 该组分对ph稳定，在叫叶范围内，抑制率80 ：对热相对较稳定，在90以下仍有75的抑制率。过柱后的粗组分icso约为0
2 have the anti - cancer function : the performance is can keep normal cell cancer from turn , the leading cancer cell recover normally , such as propagate to have to the cancer cells , such as cancer of the liver , lung cancer , cervical cancer and the melanin lump . etc 2具有抗癌的作用：表现在能防止正常细胞癌化，引导癌细胞恢复正常，如对肝癌肺癌子宫颈癌黑色素瘤等癌细胞的增殖有明显的抑制作用，抑制率
Investigations were carried to assess the sublethal effects of the insecticides ( fipronil and triazophos ) and the heavy metals ( cd2 + and pb2 + ) on activities of brain acetylcholinesterase ( ache ) , hepatic glutathione - s - transferases ( gst ) and liver esterases in pseudorosbora parva 处理在24h时的抑制率为79 . 5 ，是三唑磷的近4倍、处理iv的1 . 6倍，但在48h后，处理i 、处理iv和三哩磷的抑制率基本接近。
The results showed that extract of m . arvensis had a stronger inhibitory effect to u . virens than e . helioswpia , at 10 % of concentration , the inhibition rate to the germination of chlamdospore and conidiospore of extract of m . arvensis are all 100 % , while that of e . helioswpia were 14 . 79 % and 7 . 23 % 结果表明，薄荷提取液对病菌的抑制效果较好，在10 %浓度下对厚垣孢子和分生孢子的抑制达100 % ，而泽漆提取液的抑制率分别为14 . 79 %和7 . 23 % 。
The method was more simple than other method with good purification effect and low cost . one of the five kinds of polysaccharides , could inhibit sw1990 cell growth effectively . ir spectrum showed that the polysaccharides ( in ) which were extracted with hot water was acidity polysaccharides 接着研究了干苔多糖与固定化藻蓝蛋白的协同抑癌作用，实验表明，活性多糖组分可协同光固定化藻蓝蛋白，使对sw1990细胞的抑制率由40提高到80 。
The results showed that within the range of the dosages of exposure , the activities of brain ache and liver esterases were found to be inhibited by treatment i - iii ( fipronil - triazophos and cd2 + ) , treatment iv - vi ( fipronil - - triazophos and pb2 + ) , and triazophos , and the inhibitions of the enzyme increased with the concentration of these compounds , showing a statistically significant dose - response relationship , which can , therefore , be used as a practical biomarker for combined exposure of organophosphorous ( op ) insecticides and metals 处理i一vi在24h时对ache的联合作用基本表现为增毒作用。处理i一m和处理iv一vi对肝脏gst活性的影响趋势基本相似， 48h时均达到诱导效应最强，随着时间推移，表现为抑制作用。在% h时，处理v和vi对肝脏gst活性的抑制率分别为46 . 6 % 、 53 . 7 % ，明显高于处理11和111 。
The principle the key influential factor of enzyme inhibition spectrophotometry for determination of organophosphate and carbamate pesticide residues in vegetable had been described , and had discussed the insufficient problems such as false positive results , negative enzyme inhibition rate which exists in this enzyme inhibition spectrophotometry and why organophosphate and carbamate pesticide residues in certain vegetables such as leek cannot be determined with this enzyme inhibition spectrophotometry 摘要对利用酶抑制分光光度法检测蔬菜上有机磷和氨基甲酸酯类农药残毒的原理、最主要影响因数和存在的问题进行了探讨，重点分析了酶抑制分光光度法出现假阳性、负抑制率以及该方法不适用于检测韭菜等蔬菜中的有机磷和氨基甲酸酯类农药残留的原因。
