Hypothermia is one of the prominent features of the acute phase response to endotoxin (LPS). This study was undertaken to elucidate the effects of the COX-inhibitor Indomethacin (INDO) and the selective FLAP inhibitor MK-886 on LPS-induced hypothermia, mortality and increase in production of hypothalamic prostaglandin E(2) (PGE(2)) and leukotriene during endotoxemia. It has been demonstrated that INDO and MK-886 significantly attenuate the hypothermia induced by LPS, but MK-886 has a lesser (protective) effect than INDO. Only INDO was found to attenuate significantly the hyperthermic response to LPS. Furthermore, INDO significantly reduced the elevation in hypothalamic PGE(2) levels. MK-886 significantly reduced the elevation in hypothalamic leukotriene production only when LPS was given in a dose of 1mg/kg. Both drugs failed to reduce the elevation in plasma TNF-alpha and mortality induced by LPS. We conclude that in rats, febrile response to endotoxin involves many inflammatory mediators. However, it seems that PGE(2) and leukotrienes do not have a pivotal role in the mechanism of LPS-induced mortality.
