Cardiovascular effects of central choline during endotoxin shock in the rat.

abstract：:Chronic stimulation of beta-adrenoceptors with isoproterenol induces alteration of vascular reactivity and increases local pro-inflammatory cytokines. We investigated whether fenofibrate and pioglitazone, PPAR-alpha and -gamma agonists, respectively, improve the changes in vascular reactivity induced by isoproterenol....
