FUNCTIONAL STATUS OF PANCREATIC ISLET IN ACUTE LEUKEMIA
摘要
Using enzymatic assay and radioimmunoassay, we studied the functional status of pancreatic islet in 50 patients with acute leukemia. Oral glucose tolerance test and insulin and C peptide release were made in 40 patients before and after treatment .14 patients who revealed diabetic curve and delayed insulin and C peptide release before treatment showed normal values in 6 after therapy. Five patients with impaired glucose tolerance and decreased insulin and C peptide release before treatment showed normalization of these parameters following therapy. Five patients with normal pretreatment values disclosed abnormal post-treatment results. The remaining 16 patients displayed normal results both before and after therapy. Anti-insulin antibodies were negative, and glucagon level was normal in all the 50 patients. The red cell insulin receptor binding rate analysed in 47 patients was significantly higher than in controls (P< 0.001). We considered that the disturbed glucose metabolism in acute leukemia was not
