Repeated i.p. injections or continuous i.p. or s.c. infusion of ES induced significant increases in total serum IgE. Continuous i.p. or s.c. infusion of ES also induced ES-specific IgE antibody, while repeated i.p. injections did not. IL-4 production was increased by ex vivo stimulation with ES of mesenteric lymph node cells from repeatedly immunized mice.On the other hand, continuous intraduodenal infusion of ES induced neither total nor specific IgE responses. These results suggest that continuously secreted ES from the nematode are relevant for the up-regulation of IL-4 and IgE responses, although additional factor (s) may be necessary for the uptake of ES across the intestinal mucosal barrier.","PeriodicalId":305785,"journal":{"name":"Japanese Journal of Tropical Medicine and Hygiene","volume":"62-63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131827743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This new species seems to be also related to S. nigrifacies Datta from India and S. puliense Takaoka from Taiwan, by having the similar arrangement of six short pupal gill filaments, but is easily differentiated from these known species by the small cone-shaped tubercles on the head and thoracic integuments.","PeriodicalId":305785,"journal":{"name":"Japanese Journal of Tropical Medicine and Hygiene","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128516467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One eye of each animal in group A or B received an instillation of 1.3 X 104 (group A) or 1.3 X 105 (group B) amoeba cysts/eye; phosphate-buffered saline (PBS) solution was instilled into the contralateral eye as the control; animals in groups C and D received intrastromal injections of 5.0 X 103 (group C) or 1.5 X 104 (group D) cysts/eye in one eye and injection of an equal volume of PBS in the contralateral eye. Animals were observed daily for 5 to 84 days. Two rabbits in group D were killed on day 5 and enucleated eyes were embedded in paraffin and stained with hematoxylin-eosin or iodine-potassium iodide. In groups A and B, clinical signs of corneal injury disappeared by 4 hours after inoculation and signs of infection disappeared by day 2. In contrast, all eyes that had been injected with Acanthamoeba (groups C and D) developed severe keratitis, including keratoneuritis and corneal ulcer, followed by neovascularization or corneal perforation. Histologic examination showed infiltrates of leukocytes, lymphocytes, eosinophils, plasmacytes and spindle-shaped cells. The most extensive cell infiltration, and also exocytosis, liquefaction degeneration and intrastromal trophozoites, were seen in the limbic conjunctiva and palpebral conjunctiva. In addition, there was evidence of migration of inflammatory cells to the ciliary body and intravitreal space. This study showed that injection of Acanthamoeba into corneal stroma causes severe infection of the cornea and other eye tissues and that iodine-potassium iodide staining of paraffin embedded specimens is useful to detect Acanthamoeba trophozoites and cysts.","PeriodicalId":305785,"journal":{"name":"Japanese Journal of Tropical Medicine and Hygiene","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114929305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is also a report showing that the number of the published papers of noticeable infectious diseases such as AIDS, Hepatitis B, Gonorrhea, Pertussis and Tuberculosis declined by 15% or more in the USA from 1993 to 1995. It also became clear that USA is the highest in rank for the number of pa- pers published and it was well ahead of the other countries. However, as for Vibrio cholerae O139, Human T- lymphtropic Virus type 1 and Plague, a lot of papers have been published by responding countries like India, Japan and Russia, respectively.
