The theoretical plasma concentration versus time was calculated for all patients on the basis of the pharmacokinetic models described by Sheiner et al. Predicted effect versus time was calculated by following the pharmacokinetic-pharmacodynamic link model. The Ke0 was estimated by fitting a sigmoid cure. Group B was given the drug in a bolus of 2 mg.kg-1 and the Ke0 was calculated according to the method reported by Minto et al.

Thegoodness of the SD truncation v. s. the number of nucleon pairs is studied, andfound that the larger the number of pairs, the better the SD subspace.

b能谱，波函数， B(E2)和B(M1)之间有紧密的关系；SD子空间近似的好坏与价核子数的关系为：价核子对数越多，SD子空间近似越好。

Producing PHAs,and then were orientationally inserted into a prokaryotic expression vector pBV220. By analyzing the bioactibity and function of their products, the biological function of phaA, phaB and phaC was confirmed. These have been done in our laboratory. To make better use of the three genes by plant bioreactor, two groups of different plant expression vectors that can be used to produce PHAs in different plants were constructed, and the transformation of PHA in Oxalis triangnlaris has been preliminarily reseached.The following is the main results:Three plant expression vectors pBI121-A,pBI121-B and ubquiting-C, which can be used to be transformed into Oxalis triangularis were respectively constructed by using the phaA, phaB and phaC.

菌株的亚克隆基因组片段中，分离出phaA、phaB和phaC三个基因片段，定向克隆至原核表达载体pBV220，通过对其生物活性与功能分析，确证了基因phaA、phaB和phaC的生物学功能；为了通过植物生物反应器对这三个基因进一步研究利用，本实验利用这三个基因构建了两组可用于不同植物生产PHA的真核表达载体，并对紫叶酢浆草进行PHA基因遗传转化的初步研究，获得主要结果如下：利用克隆的phaA、phaB、phaC三个基因分别构建了可用于转化紫叶酢浆草表达载体pBI121-A、pBI121-B、uBquiting-C；可用于玉米转化的种子特异性表达载体p7S-A、pBI121-S-B、uBquiting-C。

There was a strong correlation between rCBV and rCBF (spearman's rank correlation coefficient=0.772, p＜0.001). 2 None of the normal brain tissue exhibited NF-κB p65 protein.

Yellow-throated marten\'s relationship is between Stone marten and Fisher marten.Fisher marten is the first species who was divided from Martes.The second one were Yellow-throated marten and Stone marten.Based on the analysis of the fossil note,Martes came from Central Europe,Fisher marten,Yellow-throated marten and Stone marten belonged to a branch which evolved to temperate zone.Boreal forest martens was another branch which evolved to cold environment.It is suggested that Yellow-throated marten and Fisher martenwere ascertained genus separately.4、By contrasting and analyzing 11 complete mitochondrial control region gene sequences of Mustelidae,the extended termination associated sequence domain、the central domain and the conserved sequence block domain were identified.A extended termination associated sequence(ETAS1) and eight conserved sequence(CSB-F、E、D、C、B、1、2、3) was indicated,and sequence mode was presented.Different kind of short repeat sequences were found between CSB1 and CSB2.With wolf as the outgroup,the phylogenetic evolution relationship of Mustelidae was analyzed using the neighbor-joining method.

而基于鼬亚科动物线粒体DNA12种重链编码蛋白基因序列及石貂和渔貂线粒体ND2和cyt b全序列，以狼、狗獾和水獭为外类群，应用NJ、MP和ML法构分别构建貂属和貂熊的系统进化树，结果表明：紫貂与日本貂亲缘关系较美洲貂近，石貂与真貂亚属亲缘关系较近，黄喉貂介于石貂和渔貂之间；渔貂是最早从貂属分化出的种类，其次是黄喉貂和石貂；结合化石记录分析，貂属起源于中欧地区，渔貂、黄喉貂和石貂属于一个向温带进化的分支，而真貂亚属为另外一个向寒冷环境进化的分支，建议将黄喉貂和渔貂分别定为单独的属。4、比对并分析11种鼬科动物线粒体DNA控制区序列，识别出延长终止序列区、中央区和保守序列区3个区域，指出了一个终止相关序列ETAS1及8个保守序列(CSB-F、E、D、C、B、1、2和3)，并给出了序列通式，在CSB1和CSB2之间发现具有不同形式的短串联重复序列。
