It contained a cDNA transcript of 1656 by in length, which encoded 552-amino acids (64868 Da in the estimated molecular weight). The fusion protein encoded by the clone NBL21 was produced in an Escherichia coli expression system and affinity purified. NBL21 fusion proteins migrated at 64 kDa and reacted to T spiralis infected mouse sera and the antibody against NBL crude antigen. Antisera were developed against NBL21 fusion proteins, which reacted to a single band migrating at 200 kDa on Western blotting analysis of crude extracts from muscle larvae, and reacted to hypodermal muscles of T spiralis on immunohistochemical staining. The antigen was recognized by the mouse serum obtained from the early phase of infection, but the antigenicity was devoid of species specificity.","PeriodicalId":305785,"journal":{"name":"Japanese Journal of Tropical Medicine and Hygiene","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124698716","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}

The leaf extract of H. macrophylla var. Otaksa or H. macrophylla had an antimalarial activity against rodent malaria, showing low parasitemia levels during administration. Following a transient recrudescence of malaria parasites in the bloodstream of treated mice, no parasites could be detected by a microscopic examination. Mice treated with the leaf extract of H. macrophylla var. Otaksa or H. macrophylla survived during the experiment, though mice in the non-treated control and other treated groups died with a gradual body weight loss from day 6 to day 10 post infection. Furthermore, the antimalarial activity of the hot-water extract of H. macrophylla leaf extract seemed higher than that of H. macrophylla var.

In the filtration technique, fecal matter is filtered through nylon mesh to concentrate the eggs and the eggs are sealed in the mounting medium by melting the mesh fibers. This technique can detect all the helminth eggs including hook worm and small Clonorchis eggs that are difficult to be recognized by the Kato-Katz technique. The rate of coincidence of the positive and negative slides of Schistosoma eggs between the two techniques was 88.7%, being statistically high. The filtration technique can detect 2.4 times number of eggs that are collected by the Kato-Katz technique, and the sealed eggs are clear enough to identify and can be preserved for months. This filtration technique, simple and suitable for field use, can contribute to find the helminth infections and to evaluate the control work even in developing countries.","PeriodicalId":305785,"journal":{"name":"Japanese Journal of Tropical Medicine and Hygiene","volume":"1 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":"114174433","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}

The idea using AnP Campylo® for cultivation of Plasmodium falciparum and its successful results were firstly reported by Haruki et al. (1997). In the present study, characterisation of 3 products of AnPs, i.e., AnP CO2® (at a gas phase of 5% CO2 and 15% O2), AnP Campylo® (10% CO2 and 10% O2) and AnP Plas® (5% CO2 and 5% O2), in an AnaeroPack Box Jar® (22×16×10.5 cm) was studied comparing with conditions in a gas incubator or gas chamber (4% CO2 and 3% O2) and in a candle jar (5% CO2 and 15% O2). The growth curves of malaria parasites showed no difference among these four conditions by incubation for 48 hr except for AnP Plas. The observed IC50 levels of chloroquine were varied much by the difference of AnPs, gas phases, the pressure in a Box Jar and free space inside. For stabilisation of IC50 testing, free space in a Box Jar should be kept equal and minimal by placing the maximal 5 test plates by adding dummy plates. By the stable results of IC50, gas phases can be divided into two groups. The one involves the gas incubator, AnP Plas® and AnP Campylo®, and the other does the candle jar and AnP CO2®. Results of chloroquine sensitivity test in the candle jar group showed more drug sensitive than in the gas incubator group. These two groups should be used properly by the purpose of field experiments. The AnP® system is proven to be a practical tool for malaria culture in the field for occupying only a small space in an incubator.","PeriodicalId":305785,"journal":{"name":"Japanese Journal of Tropical Medicine and Hygiene","volume":"37 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":"122052141","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}

Immunoelectronmicroscopy revealed intense ES immunoreactivity in the absorptive cell cytoplasm in association with lysosome-associated membrane glycoprotein (LAMP-1), and in the paracellular spaces. These results indicated that nematode antigen could be absorbed by two pathways : absorption by endocytosis and transport to lysosomes, and absorption through the paracellular pathway, suggesting altered mucosal barrier function.","PeriodicalId":305785,"journal":{"name":"Japanese Journal of Tropical Medicine and Hygiene","volume":"29 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":"130227672","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}

Compared with doxycycline, significant inhibitory effects of minocycline to chloroquine, pyrimethamine and mefloquine resistant P. falciparum strains were affirmed by the present in vitro study. By electron microscopy a number of electron dense vesicles with a single membrane bound were observed in the cytoplasm of minocycline-treated parasites, although no distinct structural alternations of mitochondria was noted.
