from this and our previous data , we conclude that in anesthetized cats , arteriolar vasodilators which increase cardiac output cause hepatic venoconstriction ( hydralazine , adrenaline , dopamine , isoproterenol , and nifedipine ) , while those which do not increase cardiac output have no effect on the hepatic venous bed ( nitroprusside and diazoxide ) or cause venodilatation ( nitroglycerine ) .
