A case of globular amyloid in the liver is reported. The amyloid nature of the unusual deposits was established by special stains and electron microscopy. The significance of globular amyloid in the liver is unknown. Of the three cases reported in the world literature, none was clinically manifest. Two occurred in patients who had diabetes mellitus.
Eight patients (different families) with syncopal attacks and a long QT interval in the ECG died suddenly. Five heard normally and three were born deaf. At postmortem examination of all eight hearts the single consistent abnormality was focal neuritis and neural degeneration within the sinus node, A-V node, His bundle and ventricular myocardium. Although the etiology of this intracardiac neural disease is uncertain, a chronic viral infection or some noninfectious degenerative process are among the plausible causes discussed. If intracardiac neuritis and neural degeneration prove to be a prevalent finding among other victims dying from the long QT syndromes, further consideration should be given to whether there is any genuine hereditary component in the pathogenesis. Because of the asymmetrical and focal distribution of the cardioneural lesions, the response to present forms of medical or surgical treatment of the lung QT syndromes may vary from benefit to harm. Until more is known of the true etiology of the neural disease, treatment will probably remain empirical in nature and should be conducted with cautious clinical observation.
BALB/c mice with Friend virus leukemia showed (i) a decreased carbon uptake by spleen and liver, observed histologically and measured by the corrected phagocytic index alpha, in spite of an increased total carbon clearance measured by the phagocytic index K, and (ii) a decreased serum hemolysin titer. Treatment with 7,12-dimethylbenz[a]anthracene (DMBA) increased the carbon uptake by spleen and liver and the serum hemolysin titer. This corresponds to the previously described effect of DMBA on Friend virus leukemia as expressed in the blood picture and the delay in the neoplastic transformation of the spleen causing a prolonged latent period and survival time and a decreased spleen weight. DMBA alone had no effect on carbon clearance and serum hemolysin titer in normal mice.
