The effect of the calcium-channel-blocking agent on the febrile response induced by ET / 中国病理生理杂志

ABSTRACT

This experiment was carried out in 65 New Zealand rabbits. The resultsrevealed that the febrile response and increaed PGE_2 level in cerebrospipel fluid (CSF) were significantly reduced when the calcium-channel-blocking agent (verapamil) wasintravenously injected prior to ET. But, verapamil had no marked effect on the increasedcAMP level in csf during ET-induced fever. It was suggested that most likely this anti-pyretic action was due to the effect on biosynthesis of PGE in hypothalamus, while,cAMP might not be involved in the mechanism of this antipyretic action.
