感染

To determine whether F3, similar to other large DNA iruses, encoded proteins that lock or delay apoptosis, mock- and F3-infected FHM cells were osmotically shocked and assayed for DNA fragmentation 3 hours later. NA fragmentation was clearly seen whether or not shocked cells were preiously infected with F3, indicating that infection with F3 did not block apoptosis induced by osmotic shock in FHM cells.

为了证明F3是否象其大DNA病毒一样编码能阻止或延迟凋亡的蛋白，在模拟感染和正常感染的FHM细胞被渗透压休克后3小时检测DNA片段化；结果显示无论是否休克F3感染都能诱导FHM细胞的DNA片段化，渗透压休克并不能阻止细胞凋亡。

We observed that cyclophosphamide-immunosuppressed adult mice were Susceptible to acute infection leading to death.4-8 week old C57 mice or outbred Kunming strain mice inoculated in-tracerebrally with HFRS virus A-16 strain and immunosuppressed with four 50mg/kg CY doses at days -1,+1,+ 2,+ 4 (day O:virai infection), developed a lethal disease94% m...

在第-l、+1，+2、+4天注射环磷酰胺50mg/kg体重(第0天感染病毒)，可使小鼠由隐性感染变为急性致死性感染，病死率为94％。在病死动物的脑，肺、肝、脾和肾等器官中，检查翻HFRS病毒抗原。这些器官显示微血管系统和实质组织的病变。这种成龄鼠模型可用于本病的研究。

Chronicity maybe result from many factors with complex mechanism.HCV may evade the host immune surveillance due to the hypermutation of HCV gene; HCV has the nature of pantropic,the tissues outside liver can provide virus for repeatedly infection of liver; The HCV receptors,such as CD81,LDL receptor,scavenger receptor B type I,L-SIGN,DC-SIGN and so on,may influence organism humoral immunity and the cellular immunity function in different degrees; HCV infection also may cause the reduction of quantity of organism immune cell or functional defect,low response of humoral immune response,tolerance of cellular immunity,then,the host finally transforms into chronic infection condition.

其慢性化的机制非常复杂，是由多个因素造成的，HCV因其基因高变性可以逃避宿主的免疫监视；HCV具有泛嗜性，肝外组织又可为肝组织的反复感染提供病毒来源；CD81、LDL受体、清道夫受体B类Ⅰ型及L-SIGN、DC-SIGN等HCV受体又可不同程度地影响机体的体液免疫和细胞免疫功能；HCV感染亦可直接导致机体免疫细胞数量减少或功能缺陷，体液免疫应答水平低下、细胞免疫耐受，宿主最终转变为慢性感染状态。

Liver pain, or even death in cirrhotic ascites; Paragonimiasis infected cysts, child or adult worms in human tissues and organs within the transitional, If staying in the lung, patients would cough, chest pain and other discomfort, live in the brain occur in epilepsy, hemiplegia, live mainly in the liver to the liver, liver pain, will live in the subcutaneous form transitional mass or nodule; Fasciolopsiasis worm infection can suffer from abdominal pain, diarrhea, malnutrition, etc.; Angiostrongylus cantonensis larvae in human migration, lesions in the brain, can cause severe headache, nausea, vomiting, fever and neck hard, there will be serious paralysis, lethargy, coma or even death.

感染食源性寄生虫病后可出现不同的症状或体征：华枝睾吸虫病的危害主要是肝受损，轻症者可出现胃肠道不适症状，重者常有肝肿大、肝区疼痛、肝硬变腹水甚至死亡；感染肺吸虫囊蚴后，童虫或成虫在人体组织与器官内移行，若寄居在肺里，患者会出现咳嗽、胸痛等不适感觉，寄居在脑中则出现癫痫、偏瘫等情况，寄居在肝内主要表现为肝大、肝痛，寄居在皮下则形成移行性包块或结节；感染姜片虫后可出现腹痛、腹泻、营养不良等；广州管圆线虫的幼虫在人体移行，病变集中在脑组织，可引起剧烈头痛、恶心、呕吐、发热及颈硬等，严重者会出现瘫痪、嗜睡、昏迷甚至死亡。

The co-infection of both viruses is quite interesting in many, many aspects. It's a much more pathopoiesis process than mono-infection.

两种病毒混合感染在许多方面都是很有意思的，这种感染要比单一感染更有致病性。

Objective To study the infection status of body lice among the middle and primary school students in rural areas and to explore the relationship between the infection and personal or social factors. Methods 758 rural students were recruited in Bengbu. The eggs, nymph or adults of Pediculus humanus corporis in the seams and folds of clothes were examined by eyes. Students were surveyed about the factors including personal hygiene habits, parents' educational level and occupation, living conditions and the number of family children by questionnaire.

目的 了解农村中小学生体虱感染状况，探讨体虱感染与人和社会因素的关系方法选取蚌埠市农村中小学生758名，肉眼观察学生贴身内衣皱缝处，发现体虱成虫、若虫及活卵者均感染阳性；对学生的卫生习惯、父母文化程度及职业、家庭居住情况和家庭子女等进行问卷调查。

With infection progress, the high intensity of staining was observed in the perinuclear regions and membrane area at 48hr and 72hr p.i., and the staining intensity showed high co-localization with DV2 E protein.

感染后24hr荧光的强度无明显变化，随着感染时间的延长，整合素β3抗原的荧光强度逐渐增强，在感染后48hr和72hr，细胞均呈现较强的荧光。

Albopictus had mesenteronal infection barrier or mesenteronal escape barrier after inoculation perorally with dengue type 2 virus.

当用不同剂量感染时，白纹伊蚊的感染阳性率和感染病毒剂量呈正相关。

HIV-infected people in a considerable part of no symptoms, but there are also some people early in the infection may have fever, weakness, pharyngodynia, joint pain, rash, swollen lymph nodes and other superficial body similar to the "cold" symptoms, some people Diarrhea can also occur.

什么是艾滋病毒感染的潜伏期？艾滋病病毒感染的人中相当一部分没有任何自觉症状，但也有一部分人在感染早期可以出现发烧、无力、咽痛、关节疼痛、皮疹、全身浅表淋巴结肿大等类似&感冒&的症状，一些人还可发生腹泻。

It caused symptomless infection on garlic, onion, shallot, Welsh onion, Chinese leek, and pea, local lesions on Chenopodium amaranticolor, C. quinoa, and Tetragonia expansa, or systemic necrosis on broad bean, but did not infect leek, narcissus, lily, belldonna lily, tobacco (5 species), Gornphrena globosa, and Physalis floridana in host range test.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
