The natural history of hepatocellular carcinoma. A study of 100 untreated cases.

The natural course of hepatocellular carcinoma (HCC) was evaluated in 100 untreated patients who were seen during recent 13 years. There were 80 males and 20 females. The macroscopic type of tumor was massive in 58, nodular in 35, and diffuse in 7 cases. Liver cirrhosis was associated with in 80% of patients. The mean survival time of overall patients was 4 months from the onset of initial symptoms to death and 2 months from admission to death. Occult and cirrhotic types of HCC showed a longer survival than frank and febrile types that had a mean survival time of all patients. The prognosis of icteric and metastatic types was poorest. Sex, tumor type, or associated cirrhosis did not substantially affect the natural course of HCC. The tumor stage and clinical stage were grossly correlated to the prognosis. In terms of symptoms, severe jaundice and ascites were the most dismal prognostic signs.

Vitamin E, catalase, manganous or cobaltous ions and dithiothreitol protect against Tween 20-induced hemolysis of vitamin E-deficient chick and kid erythrocytes.

The effective Tween 20 concentration at which 70% hemolysis was achieved in vitro correlated with the plasma vitamin E content of chicks (r = 0.85). Addition of catalase, MnCl2, CoCl2 or dithiothreitol in vitro showed significant protection against the hemolysis induced by Tween 20 in vitamin E-deficient chick and kid erythrocytes.

Plaque accumulation on Teflon-coated metal.

This study demonstrated that plaque accumulation was reduced and plaque removal facilitated by the TFE coating. These findings suggest that the TFE coating has a practical application for pontics and the proximal and cervical surfaces of crowns. These inaccessible surfaces are not easily cleaned by brushing.
