1 In this study, using rat carrageenin-induced pleurisy, we found that treatment of rats with either indomethacin or NS-398 suppressed the pleurisy at 2 h but significantly exacerbated this reaction at 48 h. Exacerbated inflammation was associated with reduced prostaglandin D(2) levels, decreased heat shock factor 1 (HSF1) activation, reduced hsp72 expression and increased activation of nuclear factor kappaB (NF-kappaB).
