中国人精子黄递酶Ⅲ型的分布及精斑黄递酶Ⅲ型的检出

应用超薄层聚丙烯酰胺凝胶等电聚焦技术对辽宁地区200例正常人精子黄递酶Ⅲ型(DIA)的分布进行了研究。其基因频率分别为DIA_3~1=0.6850,DIA_3~2=0.2875,DIA_5~3=0.0275。由阴道液、唾液、乳汁及无精子症精液不能判定DIA_3型。室温保存精斑可检出时限为9个月。     

电子计算机在非父排除率计算中的应用——中国人Rh型、Gm型和HLA型的非父排除率

本文根据 Ohno(1982)提出的单一位点复共显性基因非父排除率的公式,编制成 BASIC 程序,使用 IBM 个人电脑计算了我国长春等四个地区汉族 Gm 型的非父排除率和我国汉族等十六个民族的 Rh 型非父排除率。同时,根据 Chakravarti(1983)的多位点共显性基因非父排除率计算公式编制一个 BASIC 程序,用以计算了我国6个地区汉族及5个少数民族 HLA 型的非父排除率,其结果可用于亲权鉴定时对血型系统非父排除率的估计。     

辽宁汉族人血清类粘蛋白(ORM)型的分布及其在血痕精液(斑)及脑脊液中的检出

本文作者采用PAGIEF结合免疫固定法,调查了辽宁汉族群体(431人)ORM的分布,检出了ORM1型和ORM2型各8种表现型;对不同条件下的血痕标本进行检测,成功地检出了37℃保存2年血痕的ORM1型;首次由脑脊髓液中检出了ORM1型。ORM型的总鉴别机率为0.7043,是进行个人识别和亲子鉴定的良好遗传标记。     

RELATIONSHIP BETWEEN THE OFFENDING FREQUENCY (λ) OF IMPRISONED AND FREE OFFENDERS*

In the public debate over incarceration policy, there is considerable disagreement about what value of individual offending frequency (λ) is appropriate to use in estimating incapacitative effects. This article provides an approach for estimating the mean values of λ for diverse subsets of the total offender population, with particular emphasis on subsets generated by filtering through various stages of the criminal justice system. Sharp differences in offending frequency are displayed between robbery and burglary inmates, across three states, and particularly between resident inmates and free, active offenders. Free offenders average 1 to 3 robberies and 2 to 4 burglaries per year, while resident inmates have λ values 10 to 50 times higher. Differences result from the underlying levels of criminal activity and the sanction Levels that offenders face. A highly heterogeneous distribution of offending frequency in the total population of offenders combines with relatively Low imprisonment levels to lead to substantial selectivity of high-λ offenders among resident inmates and a correspondingly low mean value of λ among those offenders who remain free. These results have important implications for estimating incapacitative effects of an increase in incarceration, since the additional inmates will be drawn from free offenders whose mean λ is at least an order of magnitude Lower than that of the current inmate population.     

红细胞酯酶D(EsD)型的分布及血痕EsD型的检出

本文应用高压琼脂糖凝胶电泳法对沈阳地区汉族221例随机献血者的红细胞酯酶D(EsD)型进行了检测,其基因频率为 EsD~1=0.629,EsD~2=0.371。结合文献资料分析了EsD 型分布的种族差异,发现黄种人的 EsD~1频率最低,白种人及黑人最高。用本法对红细胞溶血液的最小检出量为1μl;以1μl 溶血液作成的血痕检样,室温保存2周仍可分型。以5μl 溶血液作成的血痕检样可分型时间为3周;37℃保存的溶血液可分型时间为7～8天。     

广西壮、汉人群3个基因座的遗传多态性

本研究在同一反应体系,对CSFIPO、TPOX和TH013个STR基因应复合扩增,采用高分辨率的聚丙烯酰胺变性胶电泳分离、银染技术,对广西壮、汉人群进行遗传多态性研究.结果表明3个基因应在2个群体均具有较高的Dp值,在法医学个体识别及亲权鉴定方面有重要价值.
