title: Scanning electron microscopy of the spreading of barium sulfate suspensions on the gastric mucosa of the rat. Effect of wetting agents, bile salt and lecithine.
abstract: Scanning electron microscopy was performed on the rat stomach mucosa after application of BaSO4 and three barium-containing commercial contrast media. The degree of flocculation was assessed; flocculation could be prevented by using synthetic wetting agents and by physiologic, natural emulsifiers, sodium taurocholate and lecithine.
