the acute effects of injecting i.v . bacterial endotoxin ( lps ) into rabbits in a warm environment consisted of cutaneous vasoconstriction and a decrease in respiratory rate , i.e . in an autonomic cold defence response , which was associated with a sustained increase in serum t3 concentration and caused core temperature , t3 serum concentration decreased again , whilst simultaneously the autonomic activity pattern changed to that of heat defence , comprising a rise in respiratory rate and skin vasodilatation .
