Methylene Blue dye spraying method is currently used in the endoscopic assessment of the colonic mucosa of patients with chronic ulcerative proctocolitis. We have assessed the validity of this method in the evaluation of the functional capacity of the rectal mucosa in 17 patients with ulcerative proctitis and in 5 normal subjects. The ionic transmucosal fluxes of Na+ and K+ and the potential difference were used as parameters of the mucosal function. Our results indicate that methylene blue dye spraying method can be useful in the functional assessment of the rectal epithelium, especially for differentiating normal subjects and patients with mild ulcerative proctitis.
亚甲蓝染色法目前用于慢性溃疡性直肠结肠炎患者结肠黏膜的内镜评估。我们评估了该方法在17例溃疡性直肠炎患者和5名正常受试者中评估直肠黏膜功能能力的有效性。将Na+和K+的离子跨黏膜通量以及电位差用作黏膜功能的参数。我们的结果表明，亚甲蓝染色法可用于直肠上皮的功能评估，特别是用于区分正常受试者和轻度溃疡性直肠炎患者。
