Fig. 2 Effect of IPD-1151T and N-5' on 48-hr homologous PCA in rats sensitized with anti-DNP As IgE serum. Drugs were given p.o. 30 min prior to the challenge with DNP-As. Each column represents the mean±S.E. of 6-7 animals. *,t: Statistically significant difference from the control at P < 0.05 and P < 0.01, respectively.
Fig. 3 Time course of inhibitory activity of IPD-1151T on 48-hr homologous PCA in rats sensitized with anti DNP-As-IgE serum. IPD-1151T was given p.o. in a dose of 50 mg/kg at varying times before the challenge. Each datum represents the mean±S.E. of 6-8 animals. *,t: Statistically significant difference from the control at P < 0 .05 and P < 0.01, respectively.

[Effect of suplatast tosilate (IPD-1151T) on types I-IV allergic reactions].
We examined the effect of suplatast tosilate (IPD-1151T), which exhibits a class-specific suppression of IgE antibody production, on types I-IV allerg...
