[Clinical and genetic study on human cancer--gastric cancer].

The relationship between gastrointestinal cancers and genetic influence was investigated. The subjects examined were 1211 cancer cases and 781 non-cancer cases registered to the 1st Department of Surgery of Kagoshima University Hospital from 1972 to 1980. The results were as follows: 1. Malignant cases were found in 266/1211 (22.0%) in the families of cancer probandus. Incidence was significantly (P less than 0.01) higher than that [130/781 (16.6%)] in those of non-cancer probandus. 2. Malignant cases were found in 79/356 (22.2%) in the families of gastric cancer probandus and in 51/189 (27.0%) in those of colo-rectal cancer probandus. 3. The relationship between cancer probandus and malignant cases in the families was classified according to the vertical relationship (grandparents-parents-uncle and aunt-probandus-children) and the horizontal relationship (probandus-siblings-cousin). 4. Incidence in the vertical relationships (159/266: 59.8%) was higher than that in the horizontal relationships (107/266: 40.2%). Incidence of the vertical relationships of female cancer probandus (gastric cancer: 70.4%, esophageal cancer: 55.7%, clorectal cancer: 73.9%) was significantly (P less than 0.05) higher than that in those of male cancer probandus. 5. Incidence of blood B type in male gastric cancer group tended to be less when compared with the control group (P less than 0.05). 6. Incidence of smoking habits in esophageal cancer group (82.2%) and the lung cancer group (63.4%) was significantly (P less than 0.01) higher than that in the control group (46.0%). 7. Incidence of drinking habits in the male esophageal cancer group (84.2%) was significantly (P less than 0.01) higher than that in the control group (53.0%).

The migration of lymphocytes across the vascular endothelium in lymph nodes: a scanning electron microscopic study.

Endothelial cells of Postcapillary Venules (PCV) and the passage of lymphocytes through the wall of PCV were investigated with Scanning Electron Microscope (SEM) in mesenteric lymph nodes of rats. Individual endothelial cells of PCV in the lymph node did not have flat surface or were not typically cubic, but swelled at the central part assuming a foot ball-like shape. Circulating lymphocytes are considered to migrate into lymphatic tissues through the wall of PCV from the blood stream. Two hypotheses, inter-endothelial cell passage and intra-endothelial cell passage, have been proposed. The three-dimensional studies on lymphocytes passing the wall with SEM confirmed that migrating lymphocytes pushes their way through the intercellular space with pressing the adjoining endothelial cells from beginning to end, supporting the former hypothesis. Invasion of lymphocytes into endothelial cells were not observed.

Cholangiolocellular carcinoma of the liver: CT and MR findings.

The authors report two cases of surgically proved cholangiolocellular carcinoma of the liver. Marked contrast enhancement was observed at the periphery of the tumor on CTs and MRIs obtained during the hepatic arterial and portal venous phases, with concentric filling on the delayed images. On T1-weighted and T2-weighted MRIs, the tumor was, respectively, hypointense and hyperintense, with a central hypointense area. Therefore, helical CT and MRI features of these cholangiolocellular carcinomas were thought to be similar to those of cholangiocarcinoma.
