[alpha-glycerolphosphate dehydrogenase activity in rabbit organs and tissues in various endocrine disorders]

Activity of alpha-glycerophosphate dehydrogenase (GPDG) from rabbit tissues was distinctly decreased in hypothyroidism and increased in hyperthyroidism. In alloxane diabetes and after administration of high doses of insulin the GPDG activity, and especially the activity of its mitochondrial form, was markedly decreased in kidney and heart tissues; it was unaltered or slightly increased in liver tissue and sceletal muscles, as compared with control. The hormonal regulation of the GPDG activity is a complicated process, in which are involved not only the hormones of thyroid gland but also hormones of other endocrine glands.
