Ⅰ、甲状腺放射性碘化物摄取量和尿碘排泄量,为了探讨慢性炎性肠道疾病的病人有无缺碘倾向,分别作了两项研究。其一是检查了50例溃疡性结肠炎或局限性肠炎患者的24小时尿碘排泄量,并以102例无甲状腺或胃肠道疾病的健康者作对照。另一项研究是在38例病人和36例对照者中比较了甲状腺对~(131)I的摄取量。24小时尿碘排泄量不足40微克者,在50例 Ⅰ, thyroid radioactive iodine intake and urinary iodine excretion, in order to explore the chronic inflammatory bowel disease in patients with or without iodine deficiency tendency, made two studies respectively. One was to examine the 24-hour urinary iodine excretion in 50 patients with ulcerative colitis or Crohn’s disease and to control 102 healthy controls without thyroid or gastrointestinal disease. Another study compared thyroid uptake to 131I in 38 patients and 36 controls. 24 hours urinary iodine excretion less than 40 micrograms in 50 cases
