Clinical application of computed tomography to thyroid disease.

CT examinations were carried out in 62 patients with various thyroid disorders, 42 patients with thyroid nodules, 12 with diffuse abnormality and 8 of others. Evaluation was made whether CT could provide more information compared with other techniques. Cystic thyroid nodules could be differentiated from solid nodules with a reasonably high degree of accuracy. Uncalcified thyroid carcinoma was noticed as an ill-defined nodule with irregular wall, grossly the same in density with the muscle in plain CT, and not opacified by contrast material. CT has the ability to define the nature of the thyroid nodules better than other nontraumatic diagnostic modalities.

Various manifestations of stratification phenomenon during intravenous cholangiography.

The authors classify various types of stratification phenomenon during intravenous cholangiography. The stage of gallbladder opacification in the recumbent position has been classified as (I) mottled, (II) dendritic, (III) ring-like, and (IV) homogeneous. 'Dendritic' type of stratification phenomenon has never been reported in the literature to our knowledge. At 20 min following infusion of contrast material homogeneous opacification of the gallbladder was noticed in only 14% of patients. The others fell into types I, II or III of stratification phenomenon. In contrast, 87% of the opacified gallbladders were homogeneous on the after fatty meal film. It is therefore mandatory for diagnosis that either a 24 h film or a fatty meal film be taken to avoid the stratification phenomenon.

Increased myocardial catalase in rats fed ethanol.

The effects of chronic intake of dietary ethanol upon catalase, an enzyme capable of metabolizing ethanol, as well as upon myocardial morphology and hemodynamics, were studied in the rat. Ethanol, comprising 36% of dietary calories, administered to rats for 5 weeks, was associated with increased myocardial catalase of 45.9 +/- 3.7 IU/mg protein, compared to 21.0 +/- 1.8 IU/mg protein in pair-fed controls. The enzyme activity remained significantly elevated after 18 weeks of ethanol. Hepatic catalase did not differ in these groups. Parallel cytochemical studies confirmed the increase in myocardial catalase by demonstrating an increase in peroxisomes. Gross and light-microscopic examinations revealed no abnormalities at either 5 or 18 weeks. Remarkably few ultrastructural abnormalities were seen in this material fixed by vascular perfusion. Hemodynamic studies after 5 weeks of ethanol revealed decreased left ventricle systolic pressure and decreased mean arterial pressure but no change in ventricular filling pressure. The possibility of catalase playing a metabolic and potentially protective role in rat myocardium chronically exposed to ethanol is discussed.

Angiographic measurement of posterior fossa in the Japanese.

Measurement employing the concept of the centroid is the most accurate way to study the radiographic anatomy of the posterior fossa. The normal measurements in Japanese subjects and as reported by Ross and du Boulay correlated well. We have developed a new radiographic centroid based on the morbid anatomy of the posterior fossa. The normal measurement in the Japanese by this method is also presented.

Labelled gelfoam in transcatheter arterial embolization of renal cell carcinoma.

Six patients with renal cell carcinoma underwent transcatheter arterial embolization with Gelfoam labelled by metallic clips. The embolization procedure was more easily monitored by fluoroscopy, and the complication of peripheral embolization was prevented. Tumor regression can be evaluated by changes in the distribution of the metallic clips on plain films.
