Water extract of P. lobata was effective and its minimal concentration that inhibited 50% of the cytopathic effect (IC50) was 0.028 μg/mL.

在病毒感染前投与(p.0001)，在病毒感染时投与(p.0001)，或在病毒感染之后投与(p.0001)，皆能显示葛根热水萃取物有效抑制肠病毒71型感染造成的细胞毒杀作用。

Monilia is the most common fungi in secondary fungous infection of SAP, and the main etiology of secondary bacterial infection is Gram-negative bacteria.

SAP继发真菌感染以念珠菌感染为主，继发细菌感染则以革兰阴性菌感染为主。

Results Two cases were pulmonary tuberculosis combined aspergillus infection;one case was NK cell precursor acute leukemia and aspergillus infection;one case pernicious leucopenia and monilia infection;one case sjogren syndrome or diabetes both combined with candida albicans infection.CT basic manifestations included effusion or nodules or cavities or tumour.

结果 2例肺结核并曲霉菌感染，1例恶性白细胞细胞减少并念珠菌感染，1例急性NK细胞白血病并曲霉菌感染，干燥综合征及糖尿病各1例并白色念珠菌感染，CT基本表现为渗出、结节、空洞、肿块病灶。

Logistic regression analysis and multiple factor variance analysis showed clearing degree and H2O2 concentration promoted HPV6.11/16.18 infection and speeded infection process. But pyocyte, mycetes, neuraminidase had no dependability with HPV6.11/16.18 infection.

Logistic回归和多因素方差分析结果表明，清洁度和H2O2浓度与HPV6.11/16.18感染和加速感染进程密切相关，与脓细胞、霉菌、唾液酸苷酶并无相关性。pH值、白细胞、霉菌、滴虫、线索细胞、白细胞酯酶与HPV6.11/16.18感染虽无相关性，但在引起HPV6.11/16.18感染方面起到重要作用。

The theoretical basis for PRRS prevention is also provided from the results 2 The clinical signs changes of piglets infected with PRRSV included mild fever, periocular edema, nasal discharge, dyspnea, lethargy.

说明一旦感染PRRSV，该病毒可在感染猪体内持续存在，提示自然感染PRRSV的病例中，感染猪是本病的重要传染源，为该病的预防提供了理论依据：2。

The results indicated that the typical apoptosis was induced by PRRSV in lungs and uteri. The ultrastructural changes showed different characterizations at different stages of the infection. During the early stage from 8th h to day 3 postinfection,the apoptosis cells shrank,the cytoplasm concentrated,the chromatin condensed,the kernel disaggregated and the endoplasmic reticulum dilated. During the middle stage from day 5 to day 9 postinfection,the apoptosis cells evidently shrank,the cell membranes protu berated,the plastosome manifolded,and apoptosis bodies were found. During the last stage from day 10 upwards postinfection,the apoptosis bodies degenerated and disappeared,and no inflammation occurred. Few apoptosis cells were necrotic.

结果表明，PRRSV可诱导宿主肺和子宫发生典型的细胞凋亡，表现为细胞的超微形态结构随着病毒感染进程出现不同的特征性变化，早期（感染后第8 h至第3 d）凋亡细胞多表现为细胞体积缩小，细胞质密度增强，染色质浓缩，核仁解体，内质网扩张；中期（感染后第5 d至第9 d）凋亡细胞体积显著缩小，细胞膜突起，线粒体增多，有凋亡小体形成；晚期（感染后第10 d以后）凋亡细胞形态多表现为凋亡小体降解和消失，少数凋亡细胞在凋亡晚期表现为坏死细胞。

It is concluded that AD5/F35 vector infection has difinite selectivity to hematologic malignant cells of varions origin,the infection ability of AD5/F35 vector to cells of myeloid origin is stronger than that to cells of B cell origin,the cytotoxicity of AD5/F35 vector to infective targer cells is small.

AD5/F35载体对不同来源的血液恶性细胞的感染具有一定的选择性，对髓系来源细胞感染能力强，对B系来源细胞有一定感染能力，而且对感染靶细胞毒性小。

Over a one-year period,1 600 snails and 415 crabs were collected and examined for larval trematodes, 11.8﹪ of snails were infected with one of 8 species dominated by M.eroliae(9.9﹪), and 80﹪ of crabs harbored M.eroliae metacercariae.

调查期超过一年，在检查的1 600只螺和415只蟹中，11.8﹪的螺感染了8种马蹄属线虫中的一种，且以滨鹬马蹄吸虫的感染占优势(9.9﹪螺感染)；80﹪的蟹感染滨鹬马蹄吸虫囊蚴。

The IgE levels in other groups, in decreasing order, were 517 IU/ml for ascariasis, 514IU/ml for mixed enterobiasis and hookworm infection, 495 IU/ml for mixed ascariasis and enterobiasis, 450IU/ml for trichuriasis, 336IU/ml for mixed trichuriasis and enterobiasis, and 330 IU/ml for enterobiasis.

所有的感染羣中以钩虫感染羣的IgE值最高，其算术平均值1，298IU/ml，是正常对照羣的11.6倍，几何平均值为578IU/ml，其他感染羣IgE的几何平均值，依值的高低顺序是蛔虫单独(517IU/ml)，钧虫与蛲虫混合(514IU/ml)，蛔虫与蛲虫混合(495IU/ml)，鞭虫单独(450IU/ml)，鞭虫与蛲虫混合(336IU/ml)，蛲虫单独(330IU/ml)等感染羣。

A single dose of albendazole 400 mg was used as control.
