Carcinoma of the colon in children: report of a case and review of the literature.
Carcinoma of the colon seen in an 11-year-old boy is reported herein. The patient had advanced carcinoma of the ascending colon and died 8 months after an ileo-transversostomy had been performed as a palliative procedure. Histologically, the tumor was found to be signet-ring cell carcinoma. 29 cases of colon carcinoma reported in Japanese children under 15 years of age are also reviewed. In 19 of these patients, surgery was done as an elective procedure after the diagnosis of colon cancer had been established, but emergency surgery was performed on 10 patients for perforation or obstruction of the bowel. Curative resection was possible in 14 patients, but of these, only 3 patients survived for more than 10 years.

Transdiaphragmatic duodenal duplication in a premature infant.
A case of transdiaphragmatic duodenal duplication in a premature infant is presented. Vertebral abnormalities, which have invariably accompanied this disorder in reported cases so far, were characteristically absent. Therefore, the initial tentative diagnosis was right-sided diaphragmatic hernia. Barium examination was helpful in preoperative diagnosis.

[A case report of triple cancer (lung, stomach & liver cancer)--with special reference to operable cases reported in the literature].
A case of a triple cancer in the lung, stomach, and liver has been experienced and a subsequent operation was performed. It has been noted that the occurrence of triple cancers have increased by about four times during the last decade, no doubt due to progress in more accurate diagnoses and from therapeutic effects. However, operations involving triple cancer still are rare and such cases in the literatures are discussed.

Postoperative immunization with peanut agglutinin-binding glycoprotein from Lewis lung carcinoma in mice.
The effects of postoperative immunization with purified tumor-associated antigens on the development of lung metastases following excision of the Lewis lung carcinoma (3LL) were investigated. Soluble tumor-associated antigens were isolated from 3LL cells by detergent solubilization and purified by affinity chromatography on peanut agglutinin (PNA)-agarose. The immunization with subcutaneous injections of PNA-binding glycoproteins (PNA receptors) at the early phase following excision of primary footpad tumors of 3LL resulted in a significant decrease in incidence and size of lung metastases. The delayed immunization, however, failed to suppress the development and growth of metastatic lung tumors after surgery. The suppression in postoperative development of lung metastases was found to depend on the scheduling of immunization following local tumor excision. Splenectomy performed simultaneously with amputation of the tumor-bearing leg completely abolished the decrease in the development and growth of postoperative lung metastases in immunized mice. The involvement of the lymphoid system in the control of metastatic tumor growth was also confirmed in an in vivo tumor neutralization assay utilizing the spleen cells.

[Role of the spleen in tumor immunity--with special reference to anti-tumor immunity induced by solubilized and purified tumor-associated antigen].
The effects of post-operative immunization with purified tumor-associated antigen on the development of lung metastases following resection of the Lewis lung carcinoma (3LL) were studied. The soluble tumor-associated antigens were isolated from 3LL cells by detergent solubilization and purified by affinity chromatography on peanut agglutinin (PNA)-agarose. The immunization with subcutaneous injections of PNA-binding glycoproteins at early phase following resection of primary footpad tumors of 3LL resulted in a significant decrease in incidence and size of lung metastases. The delayed immunization, however, failed to suppress the development and growth of metastatic lung tumors after surgery. The suppression of postoperative development of lung metastases was found to depend on timing of immunization following local tumor resection. Splenectomy performed simultaneously with amputation of tumor-bearing leg was completely abolished the decrease in the development and growth of postoperative lung metastases in immunized-mice. Evidence of lymphoid system involvement in the control of metastatic tumor growth was also supported by the observation of in vivo tumor neutralization assay utilizing the spleen cells.

Effect of hepatocyte volume on energy status in the cirrhotic rat liver.
To evaluate the effect of reduced hepatocyte volume on liver energy status, the relationship between the morphologically quantified hepatocyte volume and biochemical parameters, and the difference in nuclear density between the parenchyma and stroma were assessed in rat livers with thioacetamide-induced cirrhosis. The ratio of hepatocytes to whole liver tissue, defined as the 'hepatocyte area ratio', and the nuclear densities of the parenchyma and stroma were calculated microscopically with an image analysing system. Adenine nucleotide, protein and DNA contents, and the ornithine carbamoyltransferase activity in the liver were assayed. In the cirrhotic group, adenine nucleotide content, protein content and ornithine carbamoyltransferase activity were positively correlated with the hepatocyte area ratio, whereas DNA content was negatively correlated with this ratio. The adenylate energy charge of the cirrhotic liver was maintained at a constant level regardless of the ratio. Adenine nucleotide content, protein content and ornithine carbamoyltransferase activity per fractional 'hepatocyte area ratio' in cirrhotic livers were significantly lower than in control livers. The nuclear density of the stroma was significantly greater than that of the parenchyma. These results suggest that the lowered energy status in the cirrhotic liver is not caused by reduced hepatocyte volume but rather by impaired hepatocyte metabolism. In addition, the morphological measurement with an image analysing system was found to be useful for evaluating the effects of decreased hepatocyte volume on biochemical derangements in cirrhotic tissue.

Isolation of tumor associated antigens from Lewis lung carcinoma by affinity chromatography on peanut agglutinin-agarose.
Receptors for peanut agglutinin (PNA) were isolated from Lewis lung carcinoma cells (3LL) by detergent solubilization and affinity chromatography on PNA-agarose. The isolated receptors showed heterogeneous yet distinct molecular species when they were analyzed by SDS gel electrophoresis. In vivo inoculation of the isolated receptors could induce potent cytotoxic effector cells against 3LL cells, which were detected by Winn's tumor neutralization assay. The PNA receptors were also effective in preventing the settlement of the intravenously injected 3LL tumors in the lung. These findings suggest that PNA receptors can be used for immunological therapy of certain cancers.

Prevention of pleural effusion after hepatectomy using fibrin sealant.
Retention of pleural effusion after hepatectomy is an important complication that may affect the postoperative course. However, there are few reports on its pathogenesis or preventive measures. We evaluated the mechanism of the development of this complication and preventive measures against it. During the past 4-year period, hepatectomy was performed in 77 patients, of whom 64 underwent liver mobilization by transecting the hepatic ligaments. A fibrin sealant was sprayed on the cut surface of the hepatic ligaments in randomly selected 25 of the 64 patients to determine whether this application can prevent postoperative retention of pleural effusion. Post-operative pleural effusion was not observed in any patient treated by fibrin sealant spraying but was observed in 13 (30%) of the other 39 patients treated with this sealant (p < 0.05). In addition, none of the 23 patients in whom the liver was not mobilized during hepatectomy showed postoperative pleural effusion. These results suggest that severance of the hepatic ligaments is a major cause of pleural effusion, and application of a fibrin sealant to the undersurface of the diaphragm around the insertion of the liver ligaments is useful for preventing this complication.
