to distinguish pattern differences in experimentally induced fevers , we investigated febrile responses induced by intravenous ( iv ) , intracerebroventricular ( icv ) , and intra-preoptic/anterior hypothalamic ( poa ) administration of bacterial endotoxin ( lipopolysaccharide , lps ) , endogenous pyrogen ( ep ) , human recombinant interleukin-1 alpha ( il-1 ) , and prostaglandins e2 and f2 alpha ( pge2 and pgf2 alpha ) .
