Origin of immature sulfur-rich oil in Jianghan oil field

Chemical structure of immature sulfur-rich kerogen and composition of immature sulfur-rich crude oil in Jianghun oil field have been studied. In molecular level, crude oil differs from thermolysed and chemolysed products of kerogen but does resemble the bitumen in immature sulfur-rich source rock. Therefore, immature sulfur-rich oil may be derived from the expelling of bitumen rather than from thermal cracking of kerogen.     

Cloning, construction of prokaryotic expression vector and expression ofEscherichia coli cytosine deaminase gene

Cytosine deaminase gene ofEscherichia coli strain H-30 was cloned, and its initiation codon of ‘GTG’ was mutated to ‘ATG’ by PCR. Prokaryotic recombinant expression vector pBV220-CD was constructed. Clone with high enzyme activity were selected by detecting their specific activity of cytosine deaminase. 5-FC(5-FC, 5-fluorocytosine) could induce the lethal toxicity to cells containing active CD gene. DNA sequence analysis indicated that there were 16 altered bases and 5 of them resulted in the alteration of amino acids in predicted peptide by comparing DNA sequence of the clone H-30-CD-11 with high enzyme activity with CD gene reported in Gene Bank.     

吸收比-系数倍率法及其应用——水杨酸钠、安替比林和咖啡因的同时测定

用吸收比－系数倍率法同时测定撒痛风注射液中水杨酸钠、安替比林和咖啡因三组分的含量。它们的回收率分别为１００．７％～１０２．１％、９５．９３％～１０４．５％和９７．５７％～１０１．７％。     

良好生产管理规范与全面质量管理及其在生物制品生产管理中的应用

从质量及生物制品质量的概念出发,阐述了良好生产管理规范（ＧＭＰ）管理模式和全面质量管理（ＴＱＣ）模式的基本内容及其在生物制品行业中的应用,认为ＴＱＣ是当今工业企业的现代化管理手段和方法,而ＧＭＰ是针对药品生产行业制定的一整套保证产品质量的基本要求．要想不断提高企业管理素质,改进产品质量,在生物制品企业中进行ＧＭＰ管理的同时,必须实行ＴＱＣ管理,ＴＱＣ所涉及的内容要比ＧＭＰ更广泛、更全面,而ＧＭＰ的实施又为ＴＱＣ的进行打下了良好的基础．     

莲子叶蛋白体的类型,来源与发育

莲子叶于发育的１０￣２８ｄ,以不同速率在叶肉细胞中大量积累贮存蛋白,并以不同方式组装许多形态各异、结构不同的蛋白体。按其来源与发育的特点可分４种类型：①粗面球状蛋白体;②光面球状蛋白体;③杯状蛋白体;④淀粉蛋白体。发育顺序是①,②类先形成,③,④类后发生;②类的发育贯穿整个贮存蛋白的积累期,比较了莲与其他植物蛋白体的异同。
