Using Renalin100 to disinfect the reused dialyzer and Renatro PA 100 to reuse the dialyzers, using the dialyzers of anti-HCV IgM positive patients once, reusing the dialyzers of anti-HCVIgG positive patients seperately with those of anti-HCVIgG negative patients, could prevent HCV infection. The way is safe and effective.

Results 371 bp DNA fragment was amplified from 24 different species. The sensitivity could be improved to 10-12 g. No signal was observed when human DNA,funguses and viruses were used as templates. 22 blood samples and 4 cerebrospinal fluid samples, being positive with culture, were positive by using PCR. The gramnegative and grampositive probes hybridized to clinic samples and different species, as predicted by Gram stain characteristics.

结果 对24株不同标准菌株进行PCR扩增，均出现371 bp长度的DNA片段，敏感性试验可检测出10-12 g的细菌DNA，与人类基因组DNA、真菌及病毒无交叉反应；22例血培养阳性标本及4例脑脊液培养阳性标本均扩增出371 bp长度DNA条带，反相杂交法区分革兰阳性/阴性细菌与培养结果相符。
