图2 58例9个月到34岁男性的包皮组织中5%26alpha；-还原酶II型同功酶的活性

Methods The foreskins were acquried from 58 subjects, aged 9 months to 34 years. Testosterone and dihydrotestosterone levels in these target tissues were measured by radioimmunoassay after homogenization, and the activities of 5α-reductase isozyme I and II by the methods developed in our laboratory.

58例不同生长发育阶段男子的包皮组织(年龄从出生后9月至34岁范围)，在体外测定其T、DHT水平和5α-还原酶I型和II型同功酶的活性。

The results indicated that the paralysors and excitomotors of calcium channel changed the expression level of lipoprotein lipase, peroxisome proliferators-activated receptor gamma, fatty acid synthetase, and the lipid accumulation, markedly.

结果表明：钙通道阻滞剂和激动剂显著改变了脂蛋白脂酶，过氧化物增殖激活受体γ、脂肪酸合成酶的表达水平，且影响细胞内的脂质蓄积。

Methods: Dorsal root ganglions were derived from the chick embryo and dispersed into single neuron cell,The rhCNTF was added to neuron cells and incubated for 64 hours,The activity of acid phosphatase in neuron cells was determined and the biological activity of rhCNTF was analyzed quantificationally.

从鸡胚中分离出背根神经节并制成神经细胞，将重组人睫状神经营养因子加入到细胞中继续培养64h后，用酸性磷酸酶法检测活细胞内酸性磷酸酶的活性，从而定量测定重组人睫状神经营养因子的生物活性。

When reacted four times, half of the IGAD lost activity. The average conversion of glutamate by IGAD was above 90%.

Pulp reactions were obvious during 3 days after lased. Alkaline phosphatase examination: After fixed, decalcified and selected, all experimented teeth were stained with the Ca-Co method in order to examine the alkaline phosphatase activity in dental pulp cells.

碱性磷酸酶的检测：实验牙在丙酮中固定1 d，再置入复合酸中脱钙，冰冻切片后，进行钙-钴法染色以显示牙髓细胞中碱性磷酸酶活性，根据米德冷图象分析系统测定切片的灰度值，进行统计学分析。

Lysozymes from different sources have different properties, and then the combination of different lysozymes will increase their field of application due to their co-operation action.

由于不同来源的溶菌酶性质不同，混合使用具有协同作用，将大大拓宽溶菌酶的应用领域。

The genes of hammerhead ribozymes targeted against two and three sites on negative strand of potato spindle tuber viroid were designed, synthesized and cloned according to the action manner of hammerhead ribozyme.

根据锤头型核酶的作用模式，设计、合成并克隆了特异切割马铃薯纺锤形块茎类病毒负链RNA不同区域位点的双价和三价锤头型核酶基因。

Cu2+ increased the activity of sucrase with the increase of Cu2+concentration below the certain level, and then appeared inhibition effects with the concentration increase above the level.

重金属离子 Ag＼ Hgh、Cd卜对蔗糖酶活力的抑制作用随离子浓度增大而增加，smmol几 Ag可完全抑制蔗糖酶的活性。

Activation of telomerase is thought to be regulated by the expression of its subunits, specifically hTERT.

结论为端粒酶的激活可能与其亚单位特别是端粒酶活性催化亚单位的表达、调控有关。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
