48c

Conclusion : No evident genetic association between - 48C / T polymorphism in presenilin-1 gene promoter and LOAD were found in our population-based sample .

结论在我们研究的群体中，早老素-1基因启动子区-48C/T位点的多态性与LOAD无显著的遗传相关性。

Test materials involved were three soybean varieties . They had been stored unde 37 C for 20,40,60 , and 80 days , and for 48 hours under 48C .

参试大豆品种3个，置于37℃高温下处理20、40、60、80天，以及在48℃高温下处理48小时，以常温（18～20℃）贮存大豆作对照。

Results : The 344 bp gene fragments containing - 48C / T polymorphism site were obtained by PCR based on human peripheral white blood cells genomic DNA templates of 33 AD cases and 32 controls .

结果以33例AD病例和32例对照样品的外周血白细胞基因组DNA为模板，PCR扩增出了长度为344bp的包含-48C/T多态性位点的基因片段。
