The average percentage of polymorphic bands are 72.06% for ISSR and 66.67% for RAPD respectively. The genetic diversity of ginkgo revealed by ISSR (the average effective number of alleles is 1.8780, the average Nei"s gene diversity is 0.4652, and the average Shannon"s information index is 0.6574) are all higher than those by RAPD (the average effective number of alleles is 1.7842, the average Nei"s gene diversity is 0.4317, and the average Shannon"s information index is 0.6211), while the standard errors of the parameters estimated by ISSR were lower. Therefore, ISSR molecular markers are more suited than RAPD molecular markers when testing the genetic diversity of ginkgo populations and determining the genetic relationship of among populations or among individuals which are much similar hereditarily.

本文应用RAPD和ISSR两种分子标记技术，选取中国5个可能的野生银杏居群共计75个样品，对其遗传多样性进行了研究，得出以下结论：(1)用筛选出的12个RAPD引物和10个ISSR引物进行PCR扩增，分别扩增出65条和68条重复性高、清晰的条带，多态性位点百分率分别66.67%和72.06%，ISSR揭示的银杏遗传多样性(平均有效等位基因数目为1.8780，平均基因多样度为0.4652，平均信息指数为0.6574)高于RAPD所得到的结果(平均有效等位基因数目为1.7842，平均基因多样度为0.4317，平均信息指数为0.6211)，其所估算参数的标准差要低于RAPD所估算出的值，因此，在研究亲缘关系非常近的银杏物种的遗传多样性并试图确定居群间或个体间的遗传关系时，ISSR分子标记技术比RAPD分子标记技术更为合适。

Prolonging the primary fermentation time may increase detectable rate of coliform bacterial members by different extent, and it could provides the modification basis for national standard method of multitube fermentation detection.

延长初发酵培养时间可不同程度提高大肠菌群成员检出率，为某些样本的国标大肠菌群多管发酵法修订提供了试验依据。

Methods: The time of primary fermentation was prolonged from 18~24h which is stipulated by multitube fermentation detection of coliform bacteria (GB/T4789.3-2003) to 36~48h, and 343 samples of 7 categories were investigated.

将国标大肠菌群多管发酵法(GB/T4789.28-2003)要求的初发酵培养时间18~24h延长至36~48h，对7个种类343份样本进行大肠菌群总数检测。

The results indicated that in the mountainous areas of south and west Anhui, there were 46 and 37 species of nectariferous plants, and the distribution density of Apis cerena cerena population was 2.01 and 1.95 colony·km~-2 , respectively.

皖南山区和皖西大别山区蜜粉源植物分别为46和37种，中华蜜蜂群体数量多，分布密度分别为2·01和1·95群·km-2；江淮地区和淮北平原蜜粉源植物分别为17和12种，花期短而集中，且面积大，适宜于意大利蜜蜂采集与生产，中华蜜蜂群体数量少，分布密度分别为0·06和0·02群·km-2。胡蜂捕食影响蜜蜂种群消长与分布。

Thirty patients with acute promyelocytic leukemia were observed between September 1977 and October 1985. Bleeding diathesis with petechiae or ecchymosis (80%) was the most common presenting symptom. Seventeen of 24 patients with pretreated coagulation studies were diagnosed to have disseminated intravascular coagulation. Six out of 11 patients died from intracranial hemorrhage after a mean of 2.5 days of hospitalization without any treatment. DIC was responsible for death in most cases. Induction therapy with anthracycline and cytosine arabinoside combined with prophylactic heparin infusion was carried out in the remaining 19 patients. Two patients were incompletely treated. Eight out of 17 patients achieved complete remission after a mean of 63 days following chemotherapy. The remission rate was 47%.

自1977年9月至1985年10月，观察30位急性前骨髓球性白血病病帣，临床上诊断时初发症状，主要为出血现象，尤其以瘀斑出血最多，占80%。24位病人作治疗前凝血机能检查，17位出现播散性血管内凝固症候群。11位病人没有接受治疗，其中6位经诊断后平均2.5天内死於脑内出血，凝血机能检验显示5位有播散性血管内凝固症候群。19位病人接受anthracycline与ara-C并用预防性肝素静脉滴注作缓解诱导治疗，2位不完全治疗，其余17位中有8位经过平均63天之化学治疗得到完全缓解，缓解率47%。
