13. Caracterização da fauna parasitária do pseudalopex gymnocercus (Graxaim-do-campo) e do cerdocyon thous (graxaim-do-mato) na região do Rio Grande do Sul
Com o objetivo de estudar a fauna parasitária de Cerdocyon thous e Pseudalopex gymnocercus foram estimadas a prevalência, a intensidade média de infecção e abundância de helmintos gastrintestinais e artrópodes nesses hospedeiros. Foram capturados 40 canídeos silvestres na Região Sul do Estado do Rio Grande do Sul, nos municípios de Pedro Osório e

14. Capillaria hepatica in rats: focal parasitic hepatic lesions and septal fibrosis run independent courses
Capillaria hepatica causes two main lesions in the liver of rats: multifocal chronic inflammation, directly related to the presence of disintegrating parasites and their eggs, and a process of systematized septal fibrosis. The comparative behavior of these two lesions was investigated in rats experimentally infected with 600 embryonated eggs, following eithe

15. Paleoparasitological remains revealed by seven historic contexts from "Place d'Armes", Namur, Belgium
Human occupation for several centuries was recorded in the archaeological layers of "Place d'Armes", Namur, Belgium. Preventive archaeological excavations were carried out between 1996/1997 and seven historical strata were observed, from Gallo-Roman period up to Modern Times. Soil samples from cesspools, latrines, and structures-like were studied and reveale

16. Changes induced in Biomphalaria glabrata (Say, 1818) following trials for artificial stimulation of its internal defense system
Biomphalaria glabrata can react through different pathways to Schistosoma mansoni miracidium penetration, according to the degree of resistance/susceptibility presented by different snail strains, which is a genetically determined character, resistance being the dominant feature. However, it has been observed that previous susceptible snail strain may change

17. Regressão da fibrose hepática
Durante muito tempo, se acreditou que a fibrose hepática extensa e de longa duração fosse um processo irreversível. As investigações sobre o comportamento da fibrose hepática, nas formas avançadas da esquistossomose, vieram abalar este conceito e hoje em dia está se estabelecendo a noção de que qualquer fibrose é reversível, inclusive aquela ass

18. On the presence of hepatic stellate cells in portal spaces
Previous studies in mice with hypervitaminosis A have demonstrated that fat-storing cells (hepatic stellate cells-HSCs) participate in schistosomal granuloma fibrogenesis. The origin of such cells in portal areas, away from the Disse spaces, was herein investigated. HSCs were identified in frozen sections of the liver by means of Sudan III staining. They app

19. Immunological tolerance to pig-serum partially inhibits the formation of septal fibrosis of the liver in Capillaria hepatica-infected rats
Systhematized septal fibrosis of the liver can be induced in rats either by repeated intraperitoneal injections of pig-serum or by Capillaria hepatica infection. The relationship between these two etiological factors, as far as hepatic fibrosis is concerned, is not known, and present investigation attempts to investigate it. C. hepatica-induced septal fibros

20. Experimental hepatic fibrosis due to Capillaria hepatica infection (differential features presented by rats and mice)
Rats and mice are among the most susceptible hosts for the helminth Capillaria hepatica. More information on the similarities and differences between the hepatic pathology presented by these two parasite hosts are needed, since they may represent good models for the study of hepatic fibrosis. Early changes are similar for both hosts and are represented by ne

21. Fibrose do fígado e Capillaria hepatica em ratos: efeito paradoxal nas infecções repetidas
As infecções repetidas são consideradas um importante fator na patogenia das formas mais graves das doenças causadas por parasitos. A fibrose da hepatopatia causada por Capillaria hepatica em ratos cursa na ausência de sinais de hipertensão porta ou insuficiência hepática. Depois de determinar o perfil hepático em 15 animais durante o curso de uma i

22. A contribution to the diagnosis of Capillaria hepatica infection by indirect immunofluorescence test
A highly specific pattern of immunofluorescence was noted when sera from Capillaria hepatica-infected rats were tested against the homologous worms and eggs present either in paraffin or cryostat sections from mouse liver. The pattern was represented by a combined apple green fluorescence of the internal contents of worms and eggs, which persisted in serum-d

23. Produção de fibrose septal do fígado por injeções de proteínas estranhas
Para se investigar o potencial fibrogênico de materiais derivados da Capillaria hepatica foi feita uma tentativa para se induzir fibrose hepática septal em ratos, através de injeções intraperitoneais repetidas de um extrato de fígado de camundongo infectado pela Capillaria hepática. Dois dos 10 ratos assim tratados desenvolveram fibrose. Comparativame

24. Immunological basis of septal fibrosis of the liver in Capillaria hepatica-infected rats
Rats infected with the helminth Capillaria hepatica regularly develop septal fibrosis of the liver similar to that induced by repeated ip injections of pig serum. Fibrosis starts when the focal parasitic lesions begin to show signs of resorption, thus suggesting an immunologically mediated pathogenesis of this fibrosis. To explore this possibility, the devel
