对硫酸根离子检验方法的新认识

探究了检验SO42-时出现异常现象的成因,指出了F-在待检溶液酸化不到位情况下对SO42-检验可能产生干扰的实验事实。

等离子刀在膝关节镜手术中的应用

目的探讨等离子刀在膝关节镜手术中的作用。方法对68例(74膝)关节病损的患者进行了膝关节镜视下等离子刀手术,采用Lysholm膝功能评分标准,全部病例获得12～24个月,平均18.2个月随访。结果病例膝关节功能恢复良好,治疗前膝评分为(45.5+6.5),治疗后膝评分(87.2+9.4)(t=12.24,p<0.01),二者比较,有显著性差异。术后发生并发症3例,1例膝痛无缓解,1例膝痛加重,反应性关节炎1例,无关节血肿等并发症。结论等离子刀是关节镜手术有效的辅助工具,使镜下手术操作简单、出血少、术后反应小。

X-ray Examination of the Complex Adenosine, Guanosine and Cytidine with UO2^2＋ Ions

Interaction of dioxouranitm （VI） UO2^2＋ ion with Adenosine-5＇-triphosphate, Guanosine-5＇-triphosphate and 3ytidine-5＇-triphosphate were obtained a complexs of Adenosine, Guanosine and Cytidine with uranium UO2^2＋ ions and X-ray nethod to explore these complexes.

X-ray Examination of the Complex Adenosine with UO2^2＋ and Th4^＋ Ions

The authors studied the interaction of dioxouranium （VI） UO2^2＋ and thorium Th^4＋ ions with ATP （5＇-adenosine 5＇-triphosphate） and obtained a complex of adenosine with uranium UO2^2＋ and thorium Th^4＋ ions and used X-ray method to explore these complexes.
