[Behavior of the erythrocyte glucose-6-phosphate dehydrogenase in patients with functional thyroid disorders and in hyperthyroxinemic rats].
This paper deals with the activity of glucose-6-phosphate dehydrogenase in patients with hyper- and hypothyroidism as well as in hyperthyroxinaemic rats. The activity of glucose-6-phosphate dehydrogenase is enhanced in red blood cells of hyperthyreotic patients and hyperthyroxinaemic animals. The activity will be decreased to normal range in patients by administration of antithyreotic drugs, such as thiamazole. Patients with hypothyroidism exhibit decreased enzymatic activity. It is suggested that thyroid hormones stimulate the HMP-shunt in red blood cells as a defence mechanism against additional oxidative stress.
