概要: Recent technical advances in the area of abdominal magnetic resonance (MR) imaging include the development of fast scanning, the application of respiratory triggering method and the invention of phased-array receiver coil. Using these techniques, spatial and time resolution increased. Clinically, the diagnostic ability of liver tumors with MR, especially hemangioma and hepatocellular carcinoma, became superior to X-ray computed tomography. In biliary system and pancreas, noninvasive visualization of 3-dimensional display of biliary and pancreatic ducts became available by MR (MR cholangiopancreatography = MRCP). With this method, we can detect some important findings which were not obtained by other imaging modalities. 続きを見る

概要: One hundred and fourty seven cases of hepatocellular carcinoma, autopsied between 1964~1984, were clinicopathologically studied. The average age of the cases was 56 year-old, the male to female ratio was 5.13, and the average clinical course was 9.7 months. The positive cases for α-fetoprotein was 88.7%, and those for HBsAg was 43.5% of the examined cases. Macroscopically, the tumor, showing nodular type, predominantly located in the right lobe of the liver. Histopathologically, sinusoidal-trabecular type and well differentiated type of the tumor-cells were predominant. Frequency of the cases with distant metastasis was 78.2% of the total cases and that with metastasis to the lymph node was by no means low. The incidence of the tumor thrombosis into the portal vein was 76.1% and that into the hepatic vein was 44.3%. All cases of the hepatic cirrhosis combined with the hepatocellular carcinoma were posthepatitic type. The incidence of the distant metastasis was slightly higher in the cases without combination of the cirrhosis than those with combination of the cirrhosis. 続きを見る

概要: The existence of extrathymically differentiated T cells was recently demonstrated by us and other investigators. The subsequent studies revealed that the sits where such extrathymic T cells are differentiated include the hepatic sinusoids and intraepithelial sites in the intestine. Especially, extrathymic T cells generated in the liver appear even in the organs other than the liver when they are activated. They may act rationally as a surveillance system against abnormal self, and sometimes seem to induce certain autoimmune diseases when they are over-activated. In this study, we have investigated detailed sites of extrathymic T-cell differentiation in the liver and their subsequent movements by using normal mice, congenitally athymic nude mice and autoimmune MRL-lpr/lpr mice (human SLE model). 続きを見る
