The key steps were the stereospecific conversion of both allylie carbamates 10 and 13 into 11 by Li_2Cu_3(CH_2)_5 and the stereoselective hydroxylation of unsaturated side chain by OsO_4-NMO.

合成的关键步骤是用Li_2Cu_3(CH_3)_5立体专一地转化烯丙醇苯胺基甲酸酯10和13成为11和用OsO_4-NMO在化合物16的不饱和侧链上立体选择性羟基化。

In an earlier investigation [14], chemostats were inoculated with surface water from the same location as in the present study and grown for 40 days on a rich medium containing a mixture of vitamins and 3 mg/l of the fungicide 2,6-dichloro-4-nitroaniline.

在一次更加早期的调查[ 14 ]， chemostats 被接种了与水面从地点和一样在本研究中和增长40 天在一个富有的媒介包含混合物维生素和3 毫克杀真菌剂2，6 dichloro 4 硝基苯胺(dichloran 的) l 。

Because substituted anilines have Lewis acid or Lewis base group, extractions with complexing agent was conducted.

由于取代苯胺都具有Lewis酸性或Lewis碱性官能团，采用相应的络合剂进行了络合萃取的研究。

The coverslip with differentiated cells were fixed at different timepoints and used for toludine blue or inmunohistochemical dying Meanwhile, different doses of antibody to Fibronectin were added to observe aggregating phenomenon.

用2，3传代细胞按一定比例种植于24孔板内，加入TGF-β1 1，5，10ng／mL，分别于不同时间点取材固定，用于甲苯胺兰组织学染色及抗纤维连接蛋白抗体免疫组化染色。

The rats were killed by cutting theirnecks and physical blood was taken for preparing serum, interleukin 2 (IL-2) was detected by radioimmunoassay ; the spleen was taken for measuring ConA-induced reaction of lympho- cyte proliferation and induced production of IL-2; and the activity of induced production of spleen's IL-2 was determined by the means of cell proliferation of mouse thymus; the skin and trachea were taten for slice with paraffin wax, dyeing with methybenzoamine blue so as to survey mast cells .

将大鼠断头留取躯干血制备血清，用RIA法检测白细胞介素2（IL-2）；取脾脏行ConA诱导的淋巴细胞增殖反应测定和IL-2诱生；并用小鼠胸腺细胞增殖法检测脾IL-2诱生活性；取皮肤和气管做石蜡切片、甲苯胺兰染色检测肥大细胞，结果显示：应激组较对照组脾淋巴细胞增殖降低，cpm分别为9466±3.17和24019±3879（P.001）；MC明显减少，分别为8.6±3.0/HP和25.4±3.7/HP（P.001），前组形态异常较其甚（MC多较小，呈多角或不规则状），且组织中可见分散的崩解颗粒。
