An epidemiological survey of juvenile-onset insulin dependent diabetes mellitus (0-15 years) was performed in Hokkaido, Japan, during 1973-1981. The mean annual incidence during the nine year period was 1.26 per 100,000 and showed a significant increasing trend. The prevalence of IDDM at the ages of 0-15 and 6-15 were 7.7 and 11.7 per 100,000 respectively.(More)
Immunoglobulin G (IgG) fractions prepared from the serum of 18 patients with primary myxedema, 9 patients with goitrous Hashimoto's thyroiditis, and 14 normal controls were tested for their ability to alter TSH stimulation of cAMP production in cultured human thyroid cells and the binding of TSH to its receptor. When compared with the cAMP increase induced(More)
In a screening of 43 patients with primary myxedema, 9 patients were found to have IgG that inhibits the binding of 125I-thyrotrophin to its receptor (thyrotrophin-binding inhibitor immunoglobulins). Preparations of IgG from these patients did not stimulate thyroidal cyclic adenosine monophosphate generation and blocked thyroid stimulation by thyrotrophin(More)
