浅谈高等医学院校物理实验室管理与建设

确立实验技术人员的地位和作用,加强对其综合素质进行培养;努力改善实验教学环境和条件,建立完善的制度,是高等医学院校物理实验室建设管理的重要环节.本文结合我校实际谈一些体会.     

产生图的全部哈密顿回路

本文对完全图和非完全图分别给出了一个产生图中全部Hamilton回路的算法。与已有算法比较,本文提出的算法具有速度快、内存小的优点。该算法用于判别一个图是否Hamilton图效果良好。     

Intramammary expression and therapeutic effect of a human lysozyme-expressing vector for treating bovine mastitis

To develop a gene therapy strategy for treating bovine mastitis, a new mammary-specific vector containing human lysozyme (hLYZ) cDNA and kanamycin resistance gene was constructed for intramammary expression and clinical studies. After one time acupuncture or intracisternal infusion of healthy cows with 400 μg of the p215C3LYZ vector, over 2.0 μg/ml of rhLYZ could be detected by enzymatic assay for about 3 weeks in the milk samples. Western blotting showed that rhLYZ secreted into milk samples from the vector-injected cows had molecular weight similar to that of the natural hLYZ in human colostrums. Twenty days after the primary injection, the quarters were re-injected with the same vector by quarter acupuncture and even higher concentrations of rhLYZ could be detected. Indirect competitive ELISA of milk samples showed that the vector injection did not induce detectable humoral immune response against hLYZ. Clinical studies showed that twice acupuncture of quarters with the p215C3LYZ vector had overt therapeutic effect on clinical and subclinical mastitis previously treated with antibiotics, including disappearance of clinical symptoms and relatively high microbiological cure rates. These data provide a solid rationale for using the vector to develop gene therapy for treating bovine mastitis.

通过调查与访谈,对参加江苏省16届运动会高校部健美操比赛的运动员手腕部的运动损伤情况进行统计与分析,总结出造成手腕部运动损伤的原因及康复治疗的手段,以期减少不必要的运动损伤,为竞技健美操教学与训练提供有效帮助。     

VHDL语言在EDA开发软件MAX＋PlusII之应用

介绍了EDA开发工具软件MAX PlusII的主要功能；VHDL语言在进行硬件电路描述时所具有的多层次描述系统硬件功能的能力，以及在程序编译时易出现的问题。     

微分电位溶出法测定酒中痕量铅

本文研究了测定酒中痕量铅的微分电位溶出法。该法检测下限为0.1ug·L~(-1)pb,在0～10ug·L~(-1)浓度范围内有良好线性关系,用于酒中痕量铅的直接测定,其相对标准偏差小于4.5%,回收率为98.5～103%,结果令人满意。     

两段绞接式联合收割机输送槽的设计研究

本文介绍一种适宜配置在悬挂式联合收割机上的两段铰接式输送槽设计,这种输送槽后段固定,前段与割台连接并与后输送槽铰接,该铰接点为前悬挂割台的支点,借助液压油缸升降,文中对该铰接点位置的确定,以及两段输送槽铰接处的圆弧过渡板设计进行了分析研究,提供了设计方法.
