Special emphasis was placed on investigating flow distribution. Two pusher-plate pumps were used to bypass the right and left ventricles in 11 goats and 12 sheep with fibrillating hearts. The carotid artery and renal artery flows were then measured using an ultrasonic blood flow meter and the regional renal blood flow calculated using the hydrogen gas clearance method. Thirteen animals were kept alive for 24 hours in physiological hemodynamics but 10 animals died of shock within 24 hours. In the latter group, a decrease in the fractional distribution of flow to the kidney and renal cortex were observed. At a peak aortic pressure of less than 100 mmHg, the renal flow ratio was significantly correlated with the peak aortic pressure. It was thus concluded that the biventricular bypass total artificial heart operated in an independent variable rate mode maintains physiological circulation and is therefore able to substitute for native heart function in any situation.","PeriodicalId":22610,"journal":{"name":"The Japanese journal of surgery","volume":"21 3","pages":"312-21"},"PeriodicalIF":0.0,"publicationDate":"1991-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02470953","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13017482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One group of rabbits underwent resection (2.0 cm) and reanastomosis of their ileum, and another group underwent peritoneal wall abrasion. Postoperatively (1-28 days), the PEC and PTRC were collected and incubated for 5 days with 0.5 mu Ci 14C-glucosamine or 14C-proline, and the specific activity thereafter determined by beta counting. On the 1st postoperative day, the total cell number (TCN) has increased (7.7 x 10(7) cells/rabbit) to 770 per cent of the control values primarily as a result of the PMN influx (89.9 per cent). On day 3, the TCN was 6.1 x 10(7), 58.5 per cent of which comprised macrophages, which had become the principle cell type by day 5. The incorporation of proline and glucosamine into the PEC increased significantly peaking on day 7 then decreasing to the control value by day 21. Proline incorporation into the PTRC increased significantly, reaching a peak value on day 5, which decreased by day 10. Glucosamine incorporation reached a peak value on day 7 then decreased by day 10. In conclusion, the increase in glucosamine and proline incorporation into the PTRC parallels the increase in PEC, comprised principally of macrophages. These findings suggest that analysis of the metabolic activities in peritoneal activated macrophages may provide a useful tool to dissect the central mediation of postsurgical peritoneal re-epithelialization.","PeriodicalId":22610,"journal":{"name":"The Japanese journal of surgery","volume":"21 3","pages":"322-8"},"PeriodicalIF":0.0,"publicationDate":"1991-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02470954","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13017483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 66 year old man who had experienced dysphagia for 8 months was preoperatively diagnosed as simultaneously having esophageal and gastric cancers. Thus, a lower esophagectomy and total gastrectomy with paraesophageal and paragastric lymph node dissection were performed. The surgical specimen revealed an ulcerative tumor in the lower esophagus and a slightly depressed lesion with a central elevation similar to that of early type IIc + IIa gastric cancer in the upper part of the stomach. Microscopically, the esophageal tumor was revealed to be well differentiated squamous cell carcinoma while the gastric tumor was found to be early gastric cancer with a metastatic focus of esophageal cancer in the center. Though less than one hundred cases of metastasis of cancer to cancer have previously been reported, metastasis from cancer of one digestive organ to that of another digestive organ is very rare. To our knowledge, this report represents the first case of an esophageal carcinoma metastasizing to a gastric carcinoma.","PeriodicalId":22610,"journal":{"name":"The Japanese journal of surgery","volume":"21 3","pages":"352-6"},"PeriodicalIF":0.0,"publicationDate":"1991-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02470960","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13018149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the pathogenesis of peptic ulcers associated with AA remains obscure. We measured the gastric mucosal blood flow (GMBF) endoscopically and also determined the gastric mucosal prostaglandin (PG) levels of these AA patients to investigated the mechanism behind gastric ulcer formation. Moreover, we investigated the consumption coagulopathy (CC) of AA responsible for inducing the hemorrhage from ulcers. The GMBF values of 7 AA cases, taken at the antrum, angle and corpus, were significantly decreased compared with those of control cases, while the PGE2 levels of the gastric mucosa were also significantly reduced. With regard to CC, the serum levels of fibrinogen or platelets were significantly lower than those of the control group. These results indicate that the decrease in GMBF, followed by the reduction in endogenous PG, might contribute to the gastric ulcer formation in AA patients, and that CC associated with AA could be an important factor causing the hemorrhage from these ulcers. AA patients should therefore be treated with focusing attention on the possibility of an associated ulcer and ulcer bleeding.","PeriodicalId":22610,"journal":{"name":"The Japanese journal of surgery","volume":"21 3","pages":"268-71"},"PeriodicalIF":0.0,"publicationDate":"1991-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02470945","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13017479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
