Case 1 was a forty-two year old man whose chief complaint was general fatigue. He had neither liver disease nor renal dysfunction. Though his serum amylase level was high,1106U, his urine amylase level was normal,241U. We suspected this pt. had macrnamylasemia. His serum amylase-isozyme pattern had special broad band and he had few normal amylase spot using Sephadex G-200 superfine thinlayer chromatography. These findings indicated that most of his serum amylase had large molecules. And we found his serum amylase was bound to lgA (K) using enzymatic immunofixation.
Case 2 was a fifty-thre e year old man who consulted our hospital because of the therapy for his diabetus mellitus. Though his serum amylase level was high,1051U, his urine amylase level was normal,187U. The characteristics of his serum amylase was similer to the first case's one.
