蛔虫

Methods The approach is based on the 39 cases which had been diagnosed as biliary duct ascariasis through ultrasonic examination and later been confirmed clinically from March,2003 to May,2006 in Changhang Hospital,according to which we analyze manifestations and clinical significance of biliary duct ascariasis and its complications.

摘要］ 目的通过分析和总结胆管蛔虫症的声像图表现及其临床意义来提高对本病声像图的认识及诊断符合率方法通过回顾性分析我院2003年4月～2006年5月超声诊断胆管蛔虫症、临床最后确诊的39例病例资料，分析胆管蛔虫及其并发症在超声图像上的表现和临床意义。

Clinical practice has proved that ultrasonic examination is the first reference to diagnose biliary duct ascariasis and this disease has complicated manifestations on ultrasonic figures.

超声检查是临床诊断胆管蛔虫症的首选方法，胆管蛔虫症在超声图像上的表现复杂样，正确认识胆管蛔虫症的声像特征，才能好地发挥超声检查对本病的诊断价值。

Stomachache children is a more common diseases, some caused by the roundworm, such as intestinal ascariasis, biliary disorders; some stomach pain may be caused by certain diseases, such as appendicitis, pancreatitis as well as the intestinal tract and other infections and indigestion.

儿童肚子痛是一种较为常见的疾病，有的是由蛔虫引起的，如肠蛔虫症、胆道蛔虫症等；有的肚子痛则可能是由某些疾病引起的，如阑尾炎、胰腺炎以及肠道的感染和消化不良等。

Any of various nematode worms of the family Ascaridae, which includes the common intestinal parasite Ascaris lumbricoides.

蛔虫一种蛔虫科的线形虫，包括一般的肠内寄生虫蚓状蛔虫属

Any of various nematode worms of the family Ascaridae,which includes the common intestinal parasite Ascaris lumbricoides.

蛔虫一种蛔虫科的线形虫，包括一般的肠内寄生虫蚓状蛔虫属农民在苹果树上喷杀虫剂以灭虫。

In order to identify precisely the species of parasites eggs in kimchi and other related products and distinguish from the plant-parasitizing nemotode eggs, we researched the detection technique of Ascaris egg looked as the highest polluting risk of kimchi. The specific fluorescence quantity PCR method was established by using the Ascaris suum genome DNA as positive control,and the optimum way of breaking the eggshells in liquid nitrogen and thawing at 37℃, and the detection method of single egg.

为了精确地对从泡菜及相关产品中发现的寄生虫卵进行种类鉴定，同时与植物本身的线虫卵进行区别，我们在上述研究的基础上，以污染泡菜风险最高的蛔虫卵作为检测目标，进行了模拟阳性泡菜样品中携带蛔虫卵的荧光PCR检测技术研究，即以猪蛔虫基因组DNA为模板，建立了蛔虫特异性荧光PCR检测方法。

Prior studies have showed that pigs can be rendered immune to Ascaris suum infection by immunisation with crude antigen such as third stage larvae, and ES. Recently, some Escherichia coli-expressed recombinant antigen from A.

研究表明，猪蛔虫三期幼虫、分泌排泄物等天然抗原对宿主能提供有效的免疫保护，一些猪蛔虫融合大肠杆菌重组表达蛋白也可作为防控猪蛔虫病的候选疫苗。

Also observed that the structure of the corresponding organs of the physiological function of physiology, roundworm body wall and the body wall earthworms, roundworm longitudinal serial sections and longitudinal sections form, Once mouthparts in other nematode mouthparts comparison of the education and discussed.

并对观察到的组织的形态结构与其对应的生理器官的生理功能、蛔虫体壁与蚯蚓体壁的比较、蛔虫纵向连续切片与纵向切片形态比较、蛔虫口器于其他线虫口器比较等方面进行了讨论研究。

The objectives of the present study was to examine sequence variation in a portion of the mitochondrial NADH dehydrogenase subunit 1 gene (pnad1) within and among Toxocara canis, T. cati, T. malaysiensis, T. vitulorum and Toxascaris leonina, and to study their systematics and population genetics.

本研究旨在对弓首属犬弓首蛔虫、猫弓首蛔虫、马来西亚弓首蛔虫、牛弓首蛔虫和狮弓属狮弓蛔虫线粒体DNA中烟酰胺脱氢酶亚基I（nad1）基因部分序列（pnad1）进行比较研究，分析它们之间的序列差异和种群遗传关系。

Methods Genomic DNA from 61 samples of ascaridoid nematodes (Toxocara canis, Toxocara cati, Toxocara malaysiensis , Toxocara vitulorum and Toxascaris leonina) were collected from different geographical locations.

方法抽提61个弓首属蛔虫(包括犬弓首蛔虫、猫弓首蛔虫、马来西亚弓首蛔虫和犊弓首蛔虫)和狮弓蛔虫虫体的总DNA，用PCR方法扩增mtDNApnad4，然后用SSCP技术和DNA测序对序列进行分析研究。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
