A more general mathematical analysis of the kinetics of polycondensation-depolycondensation reactions is given in the article. Three different types of reactions are considered, namely, (1) reactions between molecules AB and AB, (2) reactions between molecules AA and BB, (3) reactions between molecules AA and BC. One of the condensation products is assumed (without loss of generality) to be water.For reactions of the first type, [p_n], the number of molecules of the n-mer (AB)_n, obeys the following Flory distribution: [p_n]=N_0p~(n-1)(1-p)~2 where N_0 denotes the total number of AB segments (including the unreacted monomers). and p, as defined by is a measure of the degree of condensation. It is shown that p is the solution of the following differential equation: dp/dt=k/2N_0(1-p)~2-k_(-1)p[H_2O] where K and k_(-1) are velocity constants of condensation and hydrolysis respectively, and [H_2O] denotes the number of water molecules. Three special cases are discussed.For reactions of the second type, three different types of condensation products are possible besides water; they obey the following distributions: [p_(2n)]=2N′_0r~(n-1)p~(2n-1)(1-p)(1-rp) [p′_(2n-1)]=N′_0r~(n-1)p~(2n-2)(1-p)~2 [p″_(2n-1)]=N′_0r~(n-2)p~(2n-2)(1-rp)~2 where N′_0 and N″_0 denote the total number of segments AA and BB respectively, r denotes the ratio N′_0/N″_0, and p, as defined by is the solution of the following differential equation: dp/dt=kn′_0/r(1-p)(1-rp)-k_(-1)P[H_2O]For reactions of the third type, six different types of condensation products are possible besides water; they obey the following distributions: [P′_(2n)]=NP~(n-1)q~n(1-p/2-q/2)(1-p) [p″_(2n)]=Np~nq~(n-1)(1-p/2-q/2_(?))(1-q) [p_(2n-1)=Np~(n-1)q~(n-1)(1-p/2-q/2)~2 [p′_(2n-1)]=N/4p~(n-2)q~n(1-p)~2 [p″_(2n-1)]=N/4p~nq~(n-2)(1-p)~2 [p′″_(2n-n)]=∈(n)N/4p~(n-1)q~(n-1)(1-p)(1-q),where N denotes either the total number of segments AA or that of BC, while p and q, as defined by satisfy the following set of differential equations: dp/dt=k′N/2(1-p)(2-p-q)-k′_(-1)p[H_O] dq/dt=k″N/2(1-q)(2-p-q)-k″_(-1)q[H_2O]

本文討論AB型,AA和BB型以及AA和BC型分子间的缩聚-裂解反應,由動力学方程出發,得到这三种类型反應过程中高聚分子的分佈情况,并求得几种不同反應條件下的缩聚度p和q是何种時间的函数,利用它们和实验数值比較,可以求得縮聚反應速度常数K和水解反應速度常数k_(-1),并在AA和BC型分子间的反應中,可以求得K'和K″的此值,藉以比较官能團B和C的活潑度。还討論了三种平均分子量的表示式、数值以及它们相互的比值,後者僅在没有水解作用的情况下,才和Flory的结果相同。

The immobilized polynucleotide phosphorylase was used to prepare poly Ⅰ and poly C. The optimal conditions for batchwise polymerization of IDP were pH 10, 3~6 mM MgCl_2 and 42℃, while those of CDP were pH 8.9, 6~12 mM MgCl_2 and 42℃. In order to minimize the hydrolysis of polymer, the preparations were carried out at pH 9 and 37℃.The immobilized PNPase column reactor had been used continuously for 1.5~2 months without loss of activity to catalyze the polymerization of IDP or CDP at pH 9, 37℃ in the presence of 6 mM MgCl_2 and 0.04% NaN_3.The reaction mixture after polymerization could be separated from immobilized PNPase by simple filtration and was protein-free. The acute animal toxicity test indicated that poly Ⅰ or poly C synthesized by immobilized enzyme column reactor met safety requirement. Therefore, the tedious step of protein removal with phenol extraction can be omitted and the industrial application of immobilized enzyme reaotor may be anticipated.

固定化PNP酶柱反应器在pH9,37℃,含有6微克分子/毫升MgCl_2,0.04%NaN_3,11~12微克分子/毫升CDP(IDP)的条件下,连续聚合反应1.5~2个月,转化率基本不变。所得的Poly I,Poly C用Lowry法测不出蛋白,紫外吸收光谱符合标准。按人体用量放大350~400倍进行急性动物毒性试验证明无毒害作用。可以省去自然酶制备Poly I,Poly C过程中酚脱蛋白的工艺。

Summary Virus isolated from bovine with epizootic fever in Beijing has been identified as probable rhabdovirus on the basis of morphological and physico—chemical propertis, 76AM strain of bovine epizootic fever virus has been propagated in baby mice and then adapted in BHK_(21) (c13) cell line. Tne following properties of the virus have been charaterized: virions are bullet shapcd, measuring 85nm in diameter and 170nm in length, containing RNA. This virion with an envelope of 11 nm thickness and studded with projection, is synthesized in the cytoplasm, assembled atcel lular membrane and released by budding. This virus is sensitive to lipidsol vents and trypsin, moderately heat sensitive and stable at low temperature. It can endure several treatments of repeated freezing and thawing, but without loss ot its infectivity to host cells. A comparision with human respiratory syncytical virus by virus neutralization test reveals no cross—reactions.

研究了从北京分离的牛流行热病毒的北76AMH毒株(牛源鼠毒适应在BHK21细胞系上的毒株)的主要特性。证明该病毒是RNA型,在宿主细胞质内装配,以出芽方式从细胞中释放并成熟。成熟病毒粒子呈典型弹状,大小为85nm×170nm毒粒。外面有厚11nm的囊膜及囊膜小体,病毒对有机溶剂和胰蛋白酶敏感。能耐受反复多次的冰冻—融化处理而不降低其感染力。初步测定了保存在不同温度条件下病毒的灭活情况。根据上述特征以及流行病学资料,该病毒与国外报导的牛暂时热病毒是一致的,而与某些在临床症状上相似的牛流行病毒如牛蓝舌样病毒、牛鼻气管炎病毒和牛呼吸道合胞体病毒却有本质的区别。
