Effect of chronic lithium administration on endothelium-dependent relaxation in rat aorta.

1. The effects of chronic lithium administration on the relaxant responses of rat thoracic aortic rings in the presence of indomethacin (a cyclo-oxygenase inhibitor) and/or NG-nitro-L-arginine (L-NOARG; a nitric oxide synthase inhibitor) to acetylcholine (ACh) or sodium nitroprusside were investigated in the present study. 2.

Effects of diltiazem and verapamil on ADP-induced rabbit platelet shape change and aggregation.

1. The effects of diltiazem and verapamil (two structurally different calcium channel blockers) were examined on the rabbit platelets shape change and aggregation induced by adenosine-5'-diphosphate (ADP). 2.
