Clonorchiasis has been prevalent in Shandong Province since 1962- Endemic areas were found to be no less than 107 counties. The village-based infection rate varies from 1 to 10% with an average of 1.6%. Most of the infested population were youngsters and children under 15 years of age. There was no marked difference in sex incidence. Cats, dogs and pigs were important reservoir hosts. Besides, rats and weasels were also found to be infected. The first intermediate hosts including Parafossarulus striatulus and...

Clonorchiasis has been prevalent in Shandong Province since 1962- Endemic areas were found to be no less than 107 counties. The village-based infection rate varies from 1 to 10% with an average of 1.6%. Most of the infested population were youngsters and children under 15 years of age. There was no marked difference in sex incidence. Cats, dogs and pigs were important reservoir hosts. Besides, rats and weasels were also found to be infected. The first intermediate hosts including Parafossarulus striatulus and Alocinma longicornis, had a wide distribution and large population. The second intermediate host is fresh water fish belonging to 23 species in 19 genera of 6 families, among which the small fishes such as Pseudorasbora parva, Abbotina revu-laris, Rhodeus atremius and Hemiculter kneri are mainly responsible for transmitting human infection. Children acquired the infection in most instances by eating underdone fish collected from ponds or ditches.

自1962至1990年,山东省已发现107个县(市、区)有华支睾吸虫病流行。人群感染率平均为1.5%。一般村庄,感染率在1—10%范围。感染者多为15岁以下少年儿童,男、女之间无显著差异。感染程度大多轻度,但有少数病例,可因感染严重而出现重度症状。流行区存在多种鱼、螺及家畜的感染。其中,猫、犬、猪是重要的保虫宿主,其平均感染率依次为60%、16.1%和6%。此外,还曾发现鼠和鼬感染本虫。第一中间宿主纹沼螺和长角涵螺分布广泛,数量众多。在已发现的6科、19属、23种淡水鱼类宿主中,麦穗鱼、棒花鱼、鳑鮍鱼、鲦鱼等一些小型野生鱼类,与人群感染本病关系密切。儿童进食不熟的坑塘小鱼,是人群感染本病的主要方式。

The effects of endocrine disruption chemicals (EDCs) on humans and wildlife and the mechanisms of action are briefly introduced. The subsequent experiments conducted by several laboratories have failed to demonstrate or duplicate the previously asserted synergism between estrogenic chemicals. The casuse\|and\|effect relationships between EDCs and reproductive alterations in wildlife and humans are still controversial among scientists.

The effects of endocrine disruption chemicals (EDCs) on humans and wildlife and the mechanisms of action are briefly introduced. The subsequent experiments conducted by several laboratories have failed to demonstrate or duplicate the previously asserted synergism between estrogenic chemicals. The casuse\|and\|effect relationships between EDCs and reproductive alterations in wildlife and humans are still controversial among scientists. It has recently been shown that sexual disruption is a widespread phenomenon in wild populations of riverine fish throughout the United Kingdom.However,the recent researches suggest that the observed induction of vitellogenin synthesis in male fishes placed downstream of effluent discharge from sewage treatment works may be due to the natural and synthetic hormones other than the previously clained alkyl phenols discomposed from non\|ionic surfactants. The currently available data are not enough for the conclusive assessment of health risks posed by EDCs to humans and wildlife.

介绍了内分泌扰乱化学品 (EDCs)的作用机制及其对野生动物影响的研究进展。内分泌化学品可能与性激素受体、甲状腺素受体和其他受体 (如芳烃受体 )结合 ,也可能通过影响动物体内激素的代谢而对动物的生长发育起调控作用。各实验室的重复实验不支持环境雌激素之间存在协同作用的结论。已报道过的人体和野生动物生殖缺陷中具有充分证据的暴露 -效应关系的实例为数不多。尽管野生鱼类变性是英国河流中的一个普遍现象 ,但进一步的实验证明污水处理场出水中的天然和合成雌激素足以引起鱼类的变性反应 ,而不是先前怀疑的非离子表面活性剂降解产物。目前尚不能对EDCs对人体和野生动物的健康风险作出正确评价 ,并有待于进一步研究

Trichodiniasis of the marine fish, Lateolabrax japonicus (Cuvier in Cuvier and Valenciennes) in the mariculture pond off the coast of Qingdao caused by trichodinid gill parasites was surveyed. 5 species were recognized as pathogens: Trichodina rectuncinata, T. domerguei, T. japonica , Trichodinella lomi and Dipartiella simplex , of which Trichodina rectuncinata was a dominant form. Histopathology of the gills of Lateolabrax japonicus infested by trichodinids was observed by scanning electron...

Trichodiniasis of the marine fish, Lateolabrax japonicus (Cuvier in Cuvier and Valenciennes) in the mariculture pond off the coast of Qingdao caused by trichodinid gill parasites was surveyed. 5 species were recognized as pathogens: Trichodina rectuncinata, T. domerguei, T. japonica , Trichodinella lomi and Dipartiella simplex , of which Trichodina rectuncinata was a dominant form. Histopathology of the gills of Lateolabrax japonicus infested by trichodinids was observed by scanning electron microscopy. It was revealed that due to the attachment of trichodinids on the surface of the gills of the host, serious physical damage could be caused to the host tissue. The pathogeny, extent of harmfulness and control approach are discussed.

报道鲈鱼的鳃寄生车轮虫病及病理组织的扫描电镜观察。病原鉴定为 :直钩车轮虫、杜氏车轮虫、日本车轮虫、劳牧小车轮虫及简单两分虫 5种车轮虫科纤毛虫 ,其中数量上占优势的为直钩车轮虫。扫描电镜观察结果表明 ,鳃寄生车轮虫可对宿主的上皮组织产生明显的机械性损伤并造成鳃丝粘液分泌增多及炎症反应。文中就海水养殖鱼类及野生鱼类由车轮虫寄生造成的危害及防治途径做了探讨。
