| sensitivity of different isolates of schistosoma japonicum from china to praziquantel. | groups of c57bl inbred mice infected with each of the 4 different isolates, (anhui, hubei, sichuan and yunnan) of schistosoma japonicum from the mainland of china were treated with praziquantel (pzq) and the parasiticidal effects were compared. worm reduction rate was recorded to assess systematically the sensitivity of 4 different isolates to pzq in the mouse. three dosage-levels of pzq, ie 150, 230 and 310 mg/kg body weight in single doses were used. the worm development rates of control group ... | 1992 | 1439978 |
| characteristics of different isolates of schistosoma japonicum from china in the final hosts. | the present paper deals with the susceptibility of common laboratory animals, such as mouse, rat, hamster, jird, rabbit and rhesus monkey, to infection with different isolates of schistosoma japonicum in the mainland of china under laboratory conditions. with the exception of the rat, all the animals under study were permissive hosts for different isolates though their worm recovery rates varied. the mean body length of pair-worms of the yunnan isolate was considerably smaller than that of the a ... | 1991 | 1948285 |
| [polymorphisms and species specificity of d2s2944 and d1s2134 loci in chinese han population in chengdu]. | to obtain the data of polymorphism distribution of the two str loci d2s2944, d1s2134 in chinese han population in chengdu and evaluate their usefulness in the field of forensic science. | 2004 | 15573761 |
| [allele frequencies and species specificity of five short tandem repeat loci of chinese han population in chengdu]. | to obtain the data in polymorphism distribution of the five short tandem repeat (str) loci: d18s979, d11s2014, d18s548, d1s1667 and gata164f07 of chinese han population in chengdu, and to evaluate their usefulness in the field of species specificity in forensic science. | 2006 | 17160956 |
| individual and village-level study of water contact patterns and schistosoma japonicum infection in mountainous rural china. | to describe the exposure patterns related to schistosomiasis transmission in 10 villages in rural xichang county, sichuan, china. | 2007 | 17956502 |
| [establishment of a mouse-lethal model for pandemic h1n1 influenza virus]. | to establish the mouse-lethal model for pandemic h1n1 influenza virus, provide an animal model for studying the pathogenicity and host adaptation of 2009 pandemic h1n1 influenza virus, and find out the key amino acid mutations which may affect viral virulence and replication. a pandemic h1n1 influenza virus strain, a/sichuan/swl1/2009 (h1n1, sc/1) was passaged in mouse lung by 15 cycles with intranasal infection. the passaged viruses were all propagated in mdck cells and sequenced. based on the ... | 2011 | 21528533 |
| spatial and temporal variability in schistosome cercarial density detected by mouse bioassays in village irrigation ditches in sichuan, china. | a mouse bioassay was used monthly over the infection season of 2001 to determine the temporal and spatial variability of schistosome cercarial density in irrigation ditches in five villages in southwestern sichuan province in the people's republic of china. analysis of variance showed that approximately half of the variability was due to the village and site within the village, with little contribution from air temperature, weekly average rainfall, or the month within the infection season in whi ... | 2004 | 15569783 |
| treatment of mannan-enhanced influenza b virus infections in mice with oseltamivir, ribavirin and viramidine. | mannan, a polysaccharide preparation from saccharomyces cerevisiae, has previously been shown to enhance influenza virus replication in mice by inhibiting host defense collectins. the use of mannan in infections may serve to broaden the types of influenza viruses that can be studied in rodent infection models. when mannan was co-administered with influenza b/sichuan/379/99 virus to mice, the animals died from the infection, whereas mice infected with only virus survived. three types of influenza ... | 2004 | 15535048 |
| [genetic polymorphisms of fabp2 and f13a1 loci in han population]. | to find more str loci usable in forensic medicine and understand the distribution of the genetic polymorphisms of two str loci fabp2 and f13a1 in the han population in chengdu. | 1998 | 9456361 |
| redescription of heligmosomoides neopolygyrus, asakawa and ohbayashi, 1986 (nematoda: heligmosomidae) from a chinese rodent, apodemus peninsulae (rodentia: muridae); with comments on heligmosomoides polygyrus polygyrus (dujardin, 1845) and related species in china and japan. | heligmosomoides neopolygyrus, asakawa and ohbayashi, 1986 (nematoda, heligmosomoidea) is redescribed from apodemus peninsulae from rangtang, sichuan, china. a morphological review of the heligmosomoides spp. belonging to the "polygyrus line" proposed by asakawa (1988) is made using new characters. this enabled us to distinguish two subspecies in mus musculus (heligmosomoides polygyrus bakeri from japan and h. p. polygyrus from china) and two valid species in apodemus spp. (h. neopolygyrus from j ... | 2012 | 23193521 |
| analysis of an outbreak of human rabies in 2009 in hanzhong district, shaanxi province, china. | between march and august 2009, there was an outbreak of rabies in both humans and dogs in hanzhong district, shaanxi province, china. about 7300 humans were bitten by dogs and 20 died of rabies due to failure to perform postexposure prophylaxis. the local authorities therefore conducted a dog slaughter campaign. from a random selection of brains of dogs culled in the campaign, 0/27 tested positive for rabies virus by immunofluorescence. of two dogs known to have bitten humans, one was shown to c ... | 2011 | 20491584 |
