Cholera toxin B subunit (CTB) and Escherichia coli heat-labile toxin (LTB) (2 micrograms), each supplemented with a trace amount of cholera toxin (CT) (0.02-20 ng), were examined for the adjuvant effect on antibody (Ab) response against influenza inactivated HA (haemagglutinin) vaccine in Balb/c mice. Each mouse received a primary intranasal (i.n.)(More)
We examined the effects of the serine protease inhibitor nafamostat mesilate on neuronal and vascular injury in rat retinas treated with N-methyl-D-aspartate (NMDA). The degree of neuronal degeneration was assessed by measuring the number of cells in the ganglion cell layer and the thickness of the inner plexiform layer. The degree of capillary degeneration(More)
We found that an antigen-specific anaphylaxis was induced by antigen challenge to the abdominal wall, ear auricle, or subcutaneous tissue in mice sensitized 9 days previously with antigen and adjuvant. The anaphylactic reaction was detected by vascular permeability at the injected site 7 minutes after challenge, which was the best time for estimation. A(More)
Macrophage migration inhibitory factor (MIF) has been shown to play an important role in a variety of inflammatory and immune-mediated diseases. The inflammatory responses contribute to retinal neuronal degeneration. However, the role of MIF in the progression of retinal degeneration has not yet been elucidated. In this study, we determined whether(More)
Resveratrol, a polyphenol found in grapes and peanuts, exerts beneficial effects on a number of diseases of cardiovascular and central nervous system. However, effects of resveratrol on the urinary system have not been fully investigated. In the present study, we examined effects of resveratrol on bradykinin-induced contraction and release of prostaglandin(More)
Anaphylactic reactions of mice sensitized percutaneously with 2,4-dinitrofluorobenzene (DNFB) were investigated by the AW method assay, which is a mouse anaphylactic model using the abdominal wall as the site for induction with either 2,4-dinitrophenyl (DNP)-human serum albumin or anti-mouse IgE antibody and then estimation of the response. DNP-specific and(More)
We noticed that an intraperitoneal injection of Freund's incomplete adjuvant (FIA) into mice could stimulate the induction of a writhing reaction. The FIA emulsion-induced writhing reaction was found to be remarkably inhibited by preadministration of oral indomethacin, a non-steroidal anti-inflammatory and analgesic drug. The induction of the writhing(More)
