钩虫

Objective To detect and compare the COI gene sequences of Necator americanus collected from the provinces of Sichuan, Hainan, Yunnan, Hubei and Jiangsu, and to analyze the genetic diversity of the geographic isolates.

目的测定和比较四川、海南、云南、湖北、江苏五省美洲钩虫细胞色素氧化酶Ⅰ基因序列，分析基因序列的多态性。

METHODS: A randomized controlled study was carried out to compare the efficacy of a single dose of 3 or 2 tablets of albendazole composite versus a single dose of 400 mg of albendazole or 10 mg base/kg of pyrantel pamoate for treatment of intestinal nematodiasis including 1 864 cases infected with hookworm, 1 568 cases infected with Ascaris, 1 785 cases in...

对成人钩虫感染者1864例、蛔虫感染者1568例和鞭虫感染者1785例及儿童蛲虫感染者373例，随机分组，比较服用单剂复方阿苯达唑3片或2片与单剂阿苯达唑400mg或噻嘧啶30mg（含基质10mg）／kg的驱虫效果和副作用。

We have obtained the anti-SEA IgY antibody, established and optimized the double antibody sandwich ELISA system to detect SEA of S. japonicum from the sera of acute and chronic patients with schistosomiasis and normal persons. The cross-reaction with sera of paragonimiasis, clonorchiasis and hookworm infections were also investigated. Our results demonstrated that the IgY-ELISA method was effective in evaluating the therapeutic effect in different parasitic burden of infected mice, which provides a novel technique for clinical diagnosis of S. japonicum infection.

本研究成功制备并鉴定了抗SEA的IgY，进行了理化性质的研究，成功建立且优化了IgG-IgY ELISA检测体系，用于正常人，急性血吸虫病患者血清和慢性血吸虫病患者血清的检测，以及肺吸虫、华支睾吸虫、钩虫患者血清的交叉反应性的分析，对感染血吸虫的小鼠进行了疗效考核，为血吸虫病的诊断提供了有效的辅助诊断方法。

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。

Methods A single dose of ivermectin 0.1, 0.2, 0.2 and 0.2 mg/kg was orally administered to cases with infection of Ascaris, hookworm, Trichuris and Enterobius respectively.

方法用伊维菌素0.1、0.2、0.2和0.2mg/kg顿服分别治疗蛔虫、钩虫、鞭虫和蛲虫感染者，并与阳性对照药阿苯达唑400mg顿服进行比较。

A majority of the population can be infected with one or more parasites, of which the most common are usually hookworm, Ascaris, giardia, and Trichuris.

最常见的寄生虫有钩虫，蛔虫，贾第虫和鞭虫。

A single dose of albendazole 400 mg was used as control. Results The egg negative conversion rates of ivermectin and albendazole were both 100%(34/34) for Ascaris infection, 17.6%(6/34)and 76.5%(26/34)respectively for hookworm infection, 67.6%(23/34)and 47.1 %(16/34)respectively for Trichuris infection,58.8%(20/34) and 100%(34/34)respectively for Enterobius infection.

结果随机双盲治疗，伊维菌素和阿苯达唑对蛔虫感染的虫卵阴转率均为100％(34/34)，对钩虫感染的虫卵阴转率分别为17.6％(6/34)和76.5％(26/34)，对鞭虫感染的虫卵阴转率分别为67.6％(23/34)和47.1％(16/34)，对蛲虫感染的虫卵阴转率分别为58.8％(20/34)和100％(34/34)。

The infection rates of Ascaris, Trichuris and Hookworm showed remarkably decreasing trends and the numbers of infected people have declined obviously.

结论开平市蛔虫、鞭虫、钩虫感染率呈显著下降趋势，感染人数显著减少；蛲虫感染率稳步下降，但仍处于较高水平；华支睾吸虫感染率呈上升趋势。

The highest infection rates of Ascaris lumbricoides and trichuris trichiura were in the group of ＜7（26.32%and7.37%）,the highest infection rate of hookworm was in the group of 41~50（36.22%）.

湖北省阳新县农村线虫流行十分严重，今后的防治工作应以降低钩虫感染为重点。

Results Of 1 224 residents, the rate of Ascaris lumbricoides, hookworm and Trichuris trichiura infection were 14.31%, 24.28% and 2.97%, respectively.

用饱和盐水漂浮法定性检查蛔虫、钩虫和鞭虫虫卵；采用透明胶纸法检查蛲虫卵。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
