In a prospective double blind study, acetylcysteine, a local and systemic respiratory tract mucolytic agent, or a placebo, were given to 100 patients prior to a double contrast barium meal to decrease the gastric mucus viscosity and to make the mucus layer thinner, in order to permit barium to outline the furrows surrounding the areae gastricae instead of the overlying thick mucus. However, acetylcysteine failed to improve either visualization of the areae gastricae or the general quality of the double contrast barium meal.
在一项前瞻性双盲研究中，在100名患者进行双重对比钡餐检查前，给予局部和全身呼吸道黏液溶解剂乙酰半胱氨酸或安慰剂，以降低胃黏液黏度并使黏液层变薄，从而使钡剂勾勒出胃小区周围的沟纹而非覆盖其上的厚黏液。然而，乙酰半胱氨酸未能改善胃小区的显影或双重对比钡餐检查的总体质量。
