Alloxan is a well-known and universally used agent for evoking experimental diabetes through its toxic effect on the B cells of the Langerhans islets. In our study, blood levels of alloxan in children with insulin-dependent diabetes mellitus were investigated. The observations were made in 68 children aged 6-15 years and in a control group of 44 healthy children in the same age range. Alloxan levels were estimated spectrophotometrically. The mean level of alloxan in blood from children with insulin-dependent diabetes mellitus was 8.76 +/- 9.64 micrograms/ml and in blood from healthy children was 1.53 +/- 1.10 micrograms/ml. The difference was statistically significant (P < 0.05). The metabolism of alloxan leads to the production of free superoxide radicals which, as is well known, injure cells and cause conditions conducive to the occurrence of diseases from autoimmunity. The results obtained suggest therefore that higher levels of alloxan in diabetic children are of significance in the onset of insulin-dependent diabetes mellitus.
