We have reported fundamental studies on the TSH immunoradiometric assay, using TSH RIABEAD II kit (Dainabot). The sensitivity of the assay was 0.03 mu IU/ml and its C.V. was 27.2%. Intra- and inter-assay C.V. were less than 5%. Dilution test and recovery test were good. Serum TSH level was 0.3-4.0 mu IU/ml in normal subjects, less than 0.03 mu IU/ml in untreated Graves' disease and subacute thyroiditis. Therefore, it was found that the clear difference exist in serum TSH levels between normal subjects and patients with untreated Graves' disease. There was a well correlation on the serum TSH levels between this method and TSH radioimmunoassay kit (Amerlex TSH, r = 0.983). Especially, the measurement of serum TSH levels, using immunoradiometric assay kit, was useful for the diagnosis of patients with Graves' disease.

A new improved technique for the visualization of intrahepatic bile ducts with oral contrast agent has been developed. The right lateral decubitus position was employed to avoid drainage of contrast medium from the common bile duct into the duodenum. 0.2-0.3 microgram/kg of Caerulein was injected intramuscularly (350 cases) or 0.02 microgram/kg of Kinevac was injected intravenously (15 cases) to induce rapid contraction of the gallbladder. The extruded contrast medium, which would normally flow into the duodenum, flowed backward into the intrahepatic bile ducts due to gravity. With this technique, improved visualization of intrahepatic bile ducts was achieved with use of oral contrast medium; it also obviated the problem of colonic gas overlapping the gallbladder and gallstones in cholecystography.
