血清阴性

Results All the 10 anti-P_(200) pemphigoid sera could react with basement membrane zoneof 5 cases of recessive dystrophic epidermolysis bullosa, while epidermolysis bullosa acquisita sera were negative in these skins.

结果发现10例抗P_(200)类天疱疮血清均与5例RDEB皮肤基底膜带反应，而获得性大疱表皮松解症血清对这些皮肤为阴性。

Results The serum antibody level reached to 0.71±0.08-0.77±0.06 after genetic vaccine pCD-HCV1(100 μg/mouse) were inoculated into the mice(n=12) three or four times while blank vector pCD-SRα1 could not induce the mice(n=8) to generate antibody response in same way.After the antibody levels in mice(n=8) immunized by pCD-HCV1 had ascended to peak value(0.71), there was no trend of descending during the following 18 weeks of detection(0.68±0.06-0.75±0.07). Specific fragment of HCV cDNA identified by polymerase chain reaction from DNA extracted from the muscles of the mice after pCD-HCV1 had beed inoculated three months.

结果 基因疫苗pCD-HCV1(100 μg/只)3-4次接种小鼠后(n=12)，血清抗体水平达0.71±0.08-0.77±0.06，空载体pCD-SRα1免疫鼠血清抗体阴性；免疫鼠(n=8)抗体水平达高峰后(0.71)，持续检测18周未见下降趋势(0.68±0.06-0.75±0.07)；pCD-HCV1免疫小鼠3个月后，用聚合酶链反应仍可从肌肉组织中扩增出特异性HCV cDNA片段；免疫鼠PBMC对HCV合成肽CP9、基因重组抗原C、E1刺激后均出现增殖反应，刺激指数分别为4.07±1.58、3.88±0.70和3.69±1.30，与pCD-SRα1免疫鼠相比，差异有显著性(P.001)。

After treating 24 hours on the gastric cancer cells with the grub extract, morphologic changes of apoptosis with chromatin margination, karyopyknosis, karyorrhexis, apoptotic body were found by the light and electron microscope.

After treating 24 hours on the gastric cancer cells with the 50g/ml of ACOL, morphologic changes of apoptosis with chromatin margination, karyopyknosis, karyorrhexis, apoptotic body were found by the light and electron microscope.

血清药理学实验结果表明，灌服抗癌口服液的含药血清组对MGC－803胃癌细胞株生长抑制率达28.91%，与阴性对照组相比有显著性差异（P.01）。

The experiment accuracy test showed that the coefficient of variation of the positive mixed serum was 5.04%, and the CV of negative mixed serum was 1.10%.

实验精确度检测阳性混合血清的变异系数为5.40%，阴性混合血清变异系数为1.10%。

These results indicate that the expressed P5 protein is an attractive source of antigen for development of an ELISA for the detection of antibodies to R. rickettsii or other agents of genus rickettsia.

以IFA结果为金标准，在立氏立克次体阳性和阴性鼠血清的检测中，以P5为包被抗原的ELISA方法的敏感性与特异性分别为100％和93.4％，表明重组P5蛋白是一个很有希望的立克次体感染的血清学诊断抗原。

Serum non-HDL-C level in the positive angiograph group was significantly higher than that in the negative group (P.01), increased with the number of affected vessels.

结果：①冠脉造影阳性组血清non-HDL-C显著高于阴性组(P.01)，并且随冠脉病变支数增多，血清non-HDL-C水平也增高。

Result150of patients and infected sheep,Cattle,Swine serum positive rates of DAgS -ELISA were 91.4%,74.6%,and 66.7%re spective-ly. In the main, DAgS -ELISA gain adva ntage over of SAT and RBPT.

结果上述3种试验对健康人、羊、牛、猪共计140份血清检查均为阴性反应，用DAgS-ELISA对布氏菌感染人、羊、牛、猪共计150份血清检查，其阳性率分别为91.4%、74.6%、66.7%及66.7%，从总体而言，检查的特异性及敏感性，以DAgS-ELISA优于SAT及RBPT。

Sometimes, they showed seronegative for all HBV markers. The definition of occult HBV is based on the existence of HBV DNA in the serum, lymphatic cells and/or liver tissue in the absence of serum HBsAg.

隐匿性HBV感染的定义为在血清学检测HBsAg阴性的情况下，在感染者的血清、淋巴细胞和/或肝组织标本中检测到HBV DNA的存在。

Methods 183 patients with seronegative viral hepatitis in serum were selected.

选择甲、乙、丙、丁、戊型病毒性肝炎血清学标志阴性血清183例。
