to determine whether the nonfebrile responses to ep also are mediated by the po and through pge , guinea pigs were injected bilaterally intra-po ( ipo ) with homologous ep ( 1 microliter ) or pge2 ( 0.1 microgram ) , and their colonic temperatures ( tco ) and plasma iron ( fe ) , zinc ( zn ) , copper ( cu ) , and n-acetylneuraminic acid ( nana ) levels were measured .
