Our results indicate that though Paragonimus skrjabini and Clonorchis sinensis were independent species, similar genes exist because of their close genetic relation. It should be further investigated whether these similar genes express common antigens resulting in cross-reaction in serodiagnosis.

RAPD结果显示斯氏肺吸虫和华支睾吸虫为2种独立的吸虫虫种，由于遗传的亲缘关系存在相同的基因，这些相同基因是否表达共同的抗原组分，并导致血清学诊断的交叉反应尚待进一步研究。

Methods ELISA was used to detect the specific IgG and IgG 4 antibodies in sera from the patients with clonorchiasis and other parasitic diseases and from healthy persons. Results The sensitivity and specificity of IgG 4 antibodies detected by ELISA in sera from the patients with clonorchiasis showed no significant difference with that of IgG detected.

Objective To analyze the polymorphism of the genomic DNA extracted from Paragonimus skrjabini and of that from Clonorchis sinensis and explore the similarity of their genes.

目的 比较分析斯氏肺吸虫和华支睾吸虫基因组多态DNA的多态性和探讨两吸虫间的相似基因。

The article reviews the advanced research on screening sheepbreeds with high resistance against fasciolosis. Screening sheep breeds with high resistance against fasciolosis has been tested by measuring parameter of plasma such as packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin concen tration, glutamate dehydrogenase, gamma glutamyl transferase and aspartate trans ferase and percent take of metacercariae. High resistance of Indonesian thin tail sheep against Fasciola gigantica has been confirmed. The mechanism of high res istance and the time of killing Fasciola gigantica has also been described.

本文综述了抗片形吸虫病绵羊品种的研究概况，通过红细胞压积、红细胞平均体积、红细胞平均血红蛋白浓度、血清谷氨酸脱氢酶、γ谷氨酰胺转移酶、天冬氨酸转氨酶等血液学参数，囊蚴感染成活率的测定等方法来筛选抗片形吸虫病的绵羊品种，研究证明印度尼西亚细尾绵羊对大片吸虫感染具有较高的抵抗力，并概述了其抗虫感染的机制及杀虫作用时间。

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。

Parasitic life cycle of complex Paragonimus turn to be host to the more complex type of indirect, intermediate hosts because of the types and number of different types of trematodes vary.

吸虫寄生性的复殖吸虫生活史为需宿主交替的较为复杂的间接发育型，中间宿主的种类和数目因不同吸虫种类而异。

Objective To analyse the soluble antigens of different developmental stages of Pagumogonimus skrjabini and deve lop a specific and sensitive serodiagnostic method for pagumogonimiasis.

作者于1994年5～6月在乌梁素海渔场进行了鱼类寄生虫种类与感染情况的调查，收集到2种绦虫，1种复殖吸虫，9种单殖吸虫，3种线虫，2种甲壳动物，3种原生动物，共20种。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
