| Research Abstract |
Plasma diaminoxidase (DAO) activities as the biomarker of gastrointestinal function were investigated in anorexia nervosa (AN) patients. Subjects were 33 female AN patients (18 AN-R and 15 AN-BP patients) and 20 healthy women. Plasma DAO activities were measured using Takagi's sensitive colorimetric assay method. The baseline plasma DAO activities in AN-R, AN-BP and healthy women were 11.5±4.7, 11.3±2.7 and 12.8±2.4 u/ml, respectively. There were no significant difference in plasma DAO activities between AN patients and controls. On the other hand, the plasma DAO activity at the time of discharge were significantly more decreased than at the time of admission (admission 11.7±3.7 u/ml, discharge 9.9±3.2 u/ml). There may be possibility of plasma DAO activity as one of biomarkers reflecting refeeding in AN patients.
