JOURNAL FREE ACCESSSera from 54 Brazilian children with a history of tropical eosinophilia syndrome were screened for toxocariasis. The enzyme-linked immunosorbent assay detected 21 positive sera (40%) . Many of these cases (15 of 21) were positive for Dilofilaria immitis as well. Of the six Toxocara-positive children with hypereosinophilia, two were asthmatic. Their sera were further examined by the Toxocara species-specific Ouchterlony's diffusion-in-gel test and one Toxocara canis and one T. cati infections were identified. This is the first report of serologically diagnosed toxocariasis in Brazil.View full abstractDownload PDF (460K) -

JOURNAL FREE ACCESSTrypanosomiasis is a parasitic disease, prevailing in both humans and animals, caused by a single-cell parasite, Trypanosoma spp. Three microbial metabolites, namely antiamoebin, F-857 and 6-MFA, were evaluated for trypanocidal activity by using a mouse model of trypanosomiasis, which is caused by T. evansi. The significance of the biological and biochemical parameters with respect to physio-pathology of trypanosomiasis and their implications in the evaluation of new trypanocidal compounds were discussed.View full abstractDownload PDF (739K) -

JOURNAL FREE ACCESSThe effect of hyperlipaemic serum on mitogen-induced T lymphocyte proliferation was investigated with cynomolgus monkeys. The mitogen-induced blastogenesis was remarkably inhibited when either hyperlipaemic or normal monkey lymphocytes were incubated with hyperlipaemic sera. Hyperlipaemic serum also inhibited ConA-induced interleukin 2 (IL-2) production as well as IL-2 receptor (IL-2R) expression of normal monkey lymphocytes. On the other hand, it showed slight inhibition of T-cell proliferation induced by adding recombinant human IL-2 to IL-2R-positive normal monkey lymphocytes. These results indicate that hyperlipaemic serum inhibited an early stage of T-cell autocrine activation pathway including IL-2 production and IL-2R expression.View full abstractDownload PDF (1562K) -

JOURNAL FREE ACCESSIn Japan, herpangina cases increase every summer with an incidence peak in July. During the past eight years from January, 1982 to December, 1989, a total of 3, 974 viruses from herpangina cases were reported from 47 participating laboratories, and coxsackie A (CA) viruses accounted for most of them, 3, 055 (76.9%) . The major types associated with herpangina were, in order of frequency, CA4, 10, 5, 6, 2 and 3, representing 87.2%-80.8% of total isolations reported for each respective type in this period. Eighty-four point four percent of the total virus isolations were from children at four years of age or younger. More than 80% of total CA virus isolations were from nasopharyngeal specimens and nearly 90% of the viruses were isolated in mice.View full abstractDownload PDF (800K)
