Abstract
150 micrograms/day of N-ethyl-N'-nitro-N-nitrosoguanidine (ENNG) was administered to a total of 8 dogs, (4 mongrels at age of 4 months and 4 beagles at age of 6 months) over a period of 8 months by Kurihara 's method. As a result of the administration, we found development of minute cancer as follows: In 3 animals, male beagle killed at 575th day, male mongrel at 1, 105th days and male mongrel at 1, 245th days, a total of 20 neoplasms of the stomach was found (18 early cancers and 2 advanced cancers). 13 of which being the minute cancer measuring less than 0.5 cm. There were 11 mucosal cancers and 2 submucosal cancers. When classified by the macroscopic pathological type, none was classified as the elevated type (I, IIa types), 5 lesions as the flat type (IIb type), and 8 lesions as the depression type (IIc type). Two lesions of submucosal cancer belonged to IIc type. When classified by the histological type, 2 were classified as papillary adenocarcinoma, 2 as well differentiated tubular adenocarcinoma, 1 as moderately differentiated tubular adenocarcinoma, 5 as poorly differentiated adenocarcinoma and 3 as signet-ring cell carcinoma.

Abstract
In order to determine the histological changes after a single infusion of bleomycin (BLM) into the aortic esophageal artery (BLM A.I.), resected specimens from 58 patients with esophageal carcinoma (27 cases with BLM A.I., 14 untreated cases, 13 cases with radiation therapy and four cases with combined therapy of radiation and BLM) were examined and evaluated by Feulgen microspectrometry for nuclear deoxyribonucleic acid (DNA) content. The histological changes following the BLM A.I. were characterized by degeneration and necrosis at the front of the invading carcinoma tissue accompanied by inflammatory cell infiltration with foreign body giant cells and fibrosis. In comparison with untreated cases, BLM-treated cases showed an increase in nuclear DNA content and a wide dispersion of the DNA values especially at the perinecrotic area and at the front of advancing carcinoma nests. Therefore, a histological effect of the BLM A.I. was shown by the measurement of the nuclear DNA content of carcinoma cells.

Abstract
A human yolk sac tumor of the thymus (YSK-1) was transplanted into athymic nude mice. Histological and ultrastructural investigations revealed that the YSK-1 tumor, even after serial transplantation in nude mice, characteristically displayed Schiller-Duval bodies, endodermal sinus structures and ultrastructural profiles, numerous microvilli, desmosome-like cell attachments, annulate lamellar structures, many lipid droplets and interspersed glycogen particles. Serological study by radioimmunoassay demonstrated AFP, CEA, HCG, alpha 1-AT and transferrin in the sera and cyst fluid of the tumor-bearing nude mice. Immunohistochemical investigation using the PAP method showed that the YSK-1 cells produced CEA, HCG, alpha 1-AT, transferrin as well as AFP. The increase in the level of AFP paralleled the increase in tumor size.

Abstract
Our previous lectin-binding study of the human colorectal mucosa revealed that, in the distal large bowel, Ulex europaeus agglutinin-L (UEA-l) binding was detectable in adenocarcinomas and adenomas, whereas it usually was not found in the normal epithelium. The aim of the present study was to obtain further information about the chemical nature of the constituents of the epithelium in polyposis coli and solitary colorectal adenoma. UEA-l binding to demonstrate alpha-L-fucosyl residue-containing glycoproteins was conducted on entire colon specimens from 4 patients with polyposis coli and on polypectomy specimens from 23 patients with solitary adenomas of the sigmoid colon and rectum with the use of a highly sensitive lectin-antilectin immunoperoxidase method. In the rectosigmoid area of all 4 patients with polyposis coli, positive UEA-l staining was observed not only in the adenomatous epithelium but also in the nonneoplastic epithelium intervening between the polyps. In contrast, in 18 of 23 patients with solitary adenomas, positive UEA-l staining was observed only in the adenomatous epithelium but not in the adjacent nonneoplastic epithelium. In the remaining 5 solitary adenomas, UEA-l staining was shown neither in the adenomatous epithelium nor in the adjacent nonneoplastic epithelium.

Abstract
Two cases of colon carcinoma coexisting with tuberculosis are reported. Both carcinoma were adjacent to scarring areas of ulcerative tuberculosis, these areas were covered by regenerated mucosa, the muscularis mucosae were lacking and there was occurrence of atypical regenerative tubules and adenomatous glands. These findings suggest that ulcerative lesions of tuberculosis may be precursors of the carcinomas. It is interesting that such carcinomas derived from a chronic inflammatory process with repetition of erosion, ulcer and consequent regeneration.

Abstract
For the purpose of verifying the effectiveness of peplomycin, one of the derivatives of bleomycin, against carcinoma of the esophagus and the safety of it, the analysis of the data for total 113 cases collected from 25 institutions in Japan was made. The results are as follows. It was effective in 19 out of 74 evaluable cases of carcinoma of the esophagus (25.7%). In case of treatment with peplomycin alone, it was effective in 6 out of 39 cases (15.4%). In case of the combination treatment with peplomycin and some other therapy, it was effective in 13 out of 35 cases (37.1%). As for the side effects, the incidence of fever was the highest in both the cases of peplomycin alone and the combination treatment such as 39.6% and 37.0%, respectively. Anorexia, nausea, vomiting, respiratory symptoms and tiredness were found in relatively many cases. In the clinical laboratory tests, the vital capacity after the treatment tended to be lower than that before the treatment, but there was little change in the hematological tests, pulmonary function test and renal function test.

Abstract
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%).

Abstract
An endodermal sinus (yolk sac) tumor was successfully transplanted into athymic nude mice. Histologic and ultrastructural investigations revealed that the transplanted tumor had a characteristic appearance with numerous Shiller-Duval bodies, endodermal sinus structures and ultrastructural profiles as previously described in human material. The endodermal sinus tumor and normal human yolk sac have been found to synthesize not only alpha-fetoprotein (AFP), but also other serum proteins, namely, albumin, prealbumin, alpha 1-antitrypsin, and transferrin. Serological study by radioimmunoassay demonstrated AFP, carcinoembryonic antigen (CEA) and human chorionic gonadotropin (HCG) in the sera of the tumor-bearing nude mice and in cyst fluid from the transplanted tumor. Immunohistochemical investigation using the unlabeled antibody peroxidase-antiperoxidase method showed using the unlabeled antibody peroxidase-antiperoxidase method showed that the tumor cells produced CEA, alpha 1-antitrypsin, transferrin, HCG as well as AFP. These immunohistochemical staining properties were correlated with the findings on radioimmunoassay.

Abstract
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.

Abstract
The possible communication between the bile canaliculus and the space of Disse was examined by experimentally inducing obstructive jaundice in rats. Blood bilirubin levels were measured and the morphological changes in the liver were observed with the scanning electron microscope (SEM); Golgi's silver impregnation was also applied to demonstrate bile canaliculus. The normal bile canaliculus issued side branches but these ended blindly and showed no communication with the space of Disse. The pericapillary space of Disse frequently extended between the liver cells forming a paracapillary space. This space reached close to the bile canaliculus but never connected with it. Seven to 14 days after bile duct ligation, when a maximal level of bilirubin was reached, direct connection of bile canaliculi and pericapillary or paracapillary spaces could be found in many places. Two routes of bile leakage were discerned: One was formed by the side branch of the bile canaliculus directly connected to the pericapillary or paracapillary space, and the other was a communication of the laterally extended bile canaliculus to the paracapillary space, the junctional complex being overrun (Fig. 12).

Abstract
This research was performed to establish a cell line from experimental bladder tumor and to discuss the biological characteristics of the cell line so established. Tissue cultures of epithelial cells were derived from a rat bladder cancer induced by BBN. The cells showed loss of contact inhibition and the phenomenon of piling up after several subcultures. Colonial cloning was used. The population doubling time of the wild strain and the colonial clones was about 30 h. The chromosomal mode ranged from triploid to tetraploid to tetraploid. Plating efficiency was well below 20%. Intraperitoneal backtransplantation into newborn Wister rats resulted in tumors in all cases. These tumors, in some parts, resembled primary transitional cell carcinoma. The major tumor cell groups, however, showed marked keratinization and the picture of squamous cell carcinoma. The nucleus/cytoplasm ratio and the numbers of nuclei, free ribosomes and intracytoplasmic microfibrils were increased. Dense microvillus arrangements characterized the electron microscopic picture. During the mitotic phase, the cells became large and globular whereas the microvilli were relatively short and were gathered profusely over the whole surface. Cells in the gap 1-synthetic phase developed lamellipodia and pseudpodia-like cytoplasmic processes and were polygonal in shape. Microvilli were present in the central part containing the nucleus, but their numbers were somewhat decreased and their height increased (scanning electron microscopy).

Abstract
The response of a cultured liver cell line to azo dyes was investigated by the application of 3'-methyl-4-dimethylaminoazobenzene (3'-Me-DAB) and 4-aminoazobenzene (AB) with observation of, in particular, the changes which occurred in plating efficiency, macromolecular synthesis and mitotic indices. The results were as follows. (1) The application of 3'-Me-DAB resulted in a decrease in size of colonies and plating efficiency of both J-5-2 cells (derived from 7-day-old rat liver tissues) and cells of the colonical clone, J-5-2cl. (2) AB caused greater inhibition of plating efficiency than did 3'-Me-DAB. (3) Both 3'-Me-DAB and AB inhibited synthesis of DNA but not of RNA or of protein. (4) AB exhibited a greater inhibitory effect on mitotic indices than did 3'-Me-DAB.
