感染

Objective Assessment was made of :(1) epidemiology of helicobacter pylori infection;(2) the relation of Hp infection to gastric precancerous disorders;(3) Hp detection rate in gastric antral cancer.

目的通过：(1)幽门螺杆菌感染的流行病学调查；(2)Hp感染与胃癌前病变的关系；(3)Hp在胃窦癌中的检出率三个方面来评价Hp感染与胃癌的相关性。

While testing on mRNA transcripts of either SCY2 or scygonadin,respectively in bacterially challenged mud crab,it was found that there was no significant change of SCY2 and scygonadin mRNA abundance in all of the tested tissues,suggesting that bacterial infection can not induce the transcription of both SCY2 and scygonadin genes.

检测细菌感染条件下锯缘青蟹各组织SCY2及Scygonadin表达情况，发现在感染后48 h内，SCY2和Scygonadin mRNA在性腺组织中的表达水平均无明显变化，说明外部细菌感染不是SCY2的直接诱导表达因素。

The four-week twice immunized hamsters acquired anti-MP in-fection capacity in local respiratory tract,as a result that swab culuturepositise was belove that of unimmunization group,and that only onehumster's lavage fluid culture was positive in immunization group.How-ever,unimmunization group positive rate of swabs and lavage fluid cul-ture was very high.This hinted that local respiratory tract's anti-MPinfection capacity was weak at the primary infection and the ability de-veloped gradually.4.The sIgA change in broncheal-lung lavage fluid.

而未免疫组咽拭子和支气管肺泡灌洗液MP分离培养的阳性均很高，说明在初次感染时，呼吸道局部防御清除MP的作用差，但随着时间的推移，其灌洗液培养的周次阳性率有下降趋势，MP培养的滴度亦随之降低，说明在感染以后随着时间的推移，呼吸道局部逐渐产生了防御、清除MP感染的作用。

The major pathogens were Blastomyces albicans and Candida tropicalis.

感染部位以尿路感染最常见，占50.66%，其次为呼吸道感染，占29.61%。

1A:Crayfish Cambarus clarkii infection group 1×dose; 1b:Crayfish control; 1c: Repeat the infection of crayfish;2a-c: Corresponding: Macrobrachium rosenbergii、Macrobrachium nipponensis、Eriochier sinensis, Sinopotamon yangtsekiense; 3b: Shrimp from Tanghai typically infected with WSSV; 3c: Healthy shrimp control.

1a 螯虾感染组，1×剂量；1b 螯虾对照组；1c 以发病螯虾为毒源进行螯虾第2次感染；2a-c 依次罗氏沼虾、日本沼虾、中华绒螯蟹感染组；3a 长江华溪蟹；3b 唐海典型病虾；3c 健康对虾对照。

By using new methods of isolating and purifying RNA of NDV, we improved the methods for detecting NDV based on Reverse transcriptase polymerase chain reaction and managed to detect velogenic NDV directly in 17 cloacal swabs specimens from different flocks including the 15 ones.

结果表明，生物学试验MDT和ICPI与ELISA阳性结果的强毒感染符合率为93.3％（14/15），而RT-PCR结果与ELISA阳性结果的强毒感染符合率为94.1％（16/17），而生物学试验加上RT-PCR结果与ELISA阳性结果的强毒感染总符合率为93.8％（30/32）。

In addition, there were 140 G + cocci, accounting for 28 %; and 31 mol...

下呼吸道感染仍以 G-杆菌感染为主，但要注意 G+球菌及霉菌感染

Study the activity of inducible nitric oxide synthase in the liver of rabbits infected with Eimeria stiedai, the concentration of nitric oxide in the serum、the coccidian oosysts per gram feces ,Score the pathologies according to anatomic structures of rabiits'livers and micoscopic pathological changes. So as to study the effect of exogenous NO and NOS of the rabbits infected with E.stiedai. The results showed that when the rabbits were infected with E.stiedai, the activity of iNOS in the liver and the concentration of NO in the serum gradually increased and they both reached the peak after 12 days in the control group , GTN and GSNO groups.

为了探讨外源性一氧化氮和一氧化氮合酶在家兔球虫感染时的作用，本试验以腹腔注射的途径给予感染斯氏艾美耳球虫的家兔NO供体硝酸甘油和亚硝基谷胱甘肽，对球虫感染家兔诱导型一氧化氮合酶活性、血清中NO的浓度、每克粪便的球虫卵囊数、肝的剖检和镜下病变及其病变计分进行了研究。

Pneumonia S Not transmitted from person to person except under extraordinary circumstances,(e.g., inhalation of aerosolized tissue phase endospores during necropsy, transplantation of infected lung) because the infectious arthroconidial form of Coccidioides immitis is not produced in humans.

除了在特定环境下(例如病理解剖时吸入气雾化的内芽胞组织、受感染的肺器官移植)，不会经由人传人感染，因为人体不会产生以 arthrocondidial 形式存在且具感染力的粗球霉菌。不会经由人传人感染。

The causes included splenic vein thrombosis (3 cases), left subphrenic infection (11 cases), abdominal cavity infection (9 cases), pulmonary infection (5 cases) and cryptogenic fever (15 cases).

发热的原因包括：脾静脉血栓3例，左膈下感染11例，腹腔感染9例，肺部感染5例，原因不明15例。

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。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
