since potent 5-ht antagonists such as cinanserin , methiothepin and methysergide , prevented the 5-ht induced-activation of na ( + ) /k ( + ) -atpase in brain homogenates , these results are discussed in relation with the possible existence of a specific 5-ht receptor controlling na ( + ) /k ( + ) -atpase activity in the rat brain .
