The effects of interferon (IFN)-gamma induced by virus infection on eosinophil reaction in allergic airway inflammation are not yet clear. We investigated the effects of lactic dehydrogenase virus (LDV) infection, which increases IFN -gamma production with no viral infection or replication in respiratory epithelium, on allergic airway hypersensitivity. LDV infection suppressed antigen-induced eosinophil recruitment into the airway in sensitized mice. IL -5 gene expression in bronchoalveolar lavage (BAL) cells was significantly suppressed in LDV -infected mice compared with uninfected controls. The numbers of total T cells and CD 4+ T cells were significantly reduced in LDV -infected mice compared with controls. The present results suggested that the increase in production of IFN -gamma by viral infection suppresses the eosinophil reaction, and this suppressive effect may be mediated by inhibition of the recruitment of CD 4+ T cell and IL -5 production. 相似文献

The microheterogeneity in bovine serum alpha 1-acid glycoprotein (alpha 1AGP) was examined by crossed affino-immunoelectrophoresis with concanavalin A(Con A). In healthy cows, serum alpha 1AGP revealed 2 fractions which were named fraction 1 and 2 according to the degree of binding affinity to Con A. The mean +/- SD of serum alpha 1AGP concentration was 0.31 +/- 0.09 g/l and the relative amounts of fraction 1 and 2 were approximately 67% and 33% respectively on this method. In bovine leukemia cases, 5 out of 8 had a high serum alpha 1AGP concentration of more than 0.7 g/l. On the electrophoretic pattern, the other 2 fractions (Con A weakly and non-reactive fractions, named fraction 3 and 4) were observed in 5 cases and their relative amounts of 4 fractions were 17.8-28.5%, 35.5-46.0%, 17.9-24.4% and 12.0-17.2%, respectively. In bovie leukemia virus infected cows with no clinical symptoms, however, serum alpha 1AGP concentration and the electrophoretic patterns were almost the same as those in healthy cows. 相似文献

Cloning and expression of the M5 RNA segment encoding outer capsid VP5 of epizootic hemorrhagic disease virus Japan serotype 2, Ibaraki virus 总被引:1,自引:0,他引:1

The complete nucleotide sequence of a cDNA clone representing the M5 RNA segment of epizootic hemorrhagic disease virus Japan serotype 2 (EHDV-2), Ibaraki virus, was determined. The M5 segment is 1641 base pairs long with the single open reading frame which predicts a polypeptide of 527 amino acids. The comparison of the amino acid sequence of the VP5 with those of EHDV-1, bluetongue virus serotype 10, and African horse sickness virus serotype 4 revealed that the protein shared 67%, 57% and 42% homologies, respectively. In addition, the VP5 protein was expressed in insect cells by recombinant baculovirus, which could be recognized by the mouse anti-EHDV-2 sera at a position of the expected 59 kDa on immunoblot analysis. 相似文献

For genotyping of feline major histocompatibility complex (FLA) class II DRB, the polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method using group-specific primers was tried. Sixty-six DRB genes were classified into 8 groups according to differences in the first 5' amino acid sequences. The group-specific primers were designed as forward ones, which were specific for 5' base sequences of genes in each group. Three to 7 appropriate restricted enzymes were selected by computer analysis for RFLP typing of the genes divided into each group. In 6 out of 9 cats, the results of DRB typed by direct sequence method agreed with results of the PCR-RFLP method using group-specific primers. In the other 3 cats, the number of genes amplified by group-specific primers was I or 2 more than those detected by direct sequence method. The direct sequence method in 9 cats identified 5 new FLA-DRB genes. The PCR-RFLP method using group-specific primers could divide 66 genes into 37 genes and 10 subgroups from the RFLP pattern. One to 6 genes in each cat, and a total of 203 genes and subgroups were detected in 68 domestic cats. The genes detected might be biased to the subgroup G1-1a (28.8%), DRB*0501 (10.3%), G1-2a (9.4%) and G6b (7.4%). The PCR-RFLP method using group-specific primers may be useful in typing FLA class II DRB. 相似文献

Beetle samples captured by traps were compared with those captured manually on flowers in a beech forest in Central Japan.
Plastic traps (Sankei Chemical Co., Ltd.) equipped with benzyl acetate were set up from the 2nd of June to the 8th of September
1994, and all beetles captured were collected every week. Beetles were also captured on wild flowers blooming along the forest
road. The traps captured 21,650 individuals of 169 species in 37 families. On the other hand, 971 individuals of 77 species
in 19 families were captured on the flowers. All of the families and 57 (74%) species of the beetles captured on the flowers
were also captured by the traps; all of the species with more than five individuals captured on the flowers were also trapped,
except for one species. The present trap system is considered to be useful for faunal monitoring of flower-visiting Coleoptera,
because the beetle fauna found on wild flowers was virtually covered by the trap capture.

In anAbies homolepis Sieb. et Zucc. forest at Matsumoto, Nagano Pref., cumulative damage byXylotrechus villioni (Villard) (Coleoptera: Cerambycidae) was observed on tree branches. Of the 14 major branches in one sample tree, six had
cumulative damage by boring larvae, of which 3 had been bored by multiple larvae. No adult emergence holes were found on the
whole tree, suggesting very low survivorship from boring larva to emerging adult. Galleries made by single larvae were often
observed to be terminated by a depression apparently carved by a picid woodpecker, suggesting that they are important predators
of the cerambycid. The manner of cicatrix formation with phloem tissue over the larval gallery in anAbies veitchii Lindl. branch at Mt. Fuji, Yamanashi Pref. is presented.
Studies onXylotrechus villioni (Villard) (Coleoptera: Cerambycidae), a primary borer of coniferous trees in Japan (III). This work was presented at the
104th Annual Meeting of Japanese Forestry Society at Morioka (April, 1993) and 20th International Congress of Entomology at
Firenze (August, 1996).

White plastic insect traps (manufactured by Sankei Chemical Co., Ltd.) equipped with four chemicals with floral scents, namely,
benzyl acetate, methyl benzoate, methyl phenylacetate and linalool, were set from June 28 to August 9, 1996. The traps were
placed in a Japanese beech (Fagus creata) forest, Minakami, Gunma Prefecture, Central Japan, and trapped longicorn beetles were collected weekly. The greatest number
of species and individuals belonged to the subfamily Lepturinae dominated by the genusPidonia. No significant differences were observed in the performances of the above four chemicals in either the total number of species
or of individuals. However, more Lamiinae species were captured in the traps with methyl phenylacetate, than in those with
methyl benzoate.
