The present study was undertaken to determine whether a biventricular bypass total artificial heart driven in an independent variable rate mode can maintain circulation in vital organs such as the brain and kidney. 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.

A debilitated 68 year old woman with an epigastric mass previously identified as a hepatic artery aneurysm (HAA) by selective angiography, developed acute epigastric pain radiating to her back. Impending rupture was diagnosed, and the patient successfully underwent surgical repair using a prosthetic patch to close the orifice of the aneurysm. HAA is uncommon, but the risk of rupture is great, being 44 per cent and the mortality rate high, being 35 per cent. Abnormal ultrasonography and CT may suggest the diagnosis, but selective arteriography is definitive. Surgical treatment is indicated in most patients, although embolization is appropriate for intrahepatic aneurysm and extremely poor risk patients.

The purpose of this study was to experimentally investigate the cellular composition of post-surgical peritoneal fluid and peritoneal tissue and determine the patterns of 14C-proline and 14C-glucosamine incorporation by the peritoneal exudative cells and peritoneal tissue repair cells (PEC and PTRC). 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.
本研究的目的是通过实验研究术后腹膜液和腹膜组织的细胞组成,并确定腹膜渗出细胞和腹膜组织修复细胞(PEC和PTRC)掺入14c -脯氨酸和14c -氨基葡萄糖的模式。一组进行回肠切除(2.0 cm)并吻合,另一组进行腹膜壁磨损。术后(1-28 d),收集PEC和PTRC,与0.5 μ Ci 14c -葡萄糖胺或14c -脯氨酸孵育5 d,随后计数测定其比活性。术后第1天,总细胞数(TCN)增加(7.7 x 10(7)个细胞/只),达到对照值的770%,主要是由于PMN流入(89.9%)。第3天,TCN为6.1 × 10(7), 58.5%为巨噬细胞,到第5天巨噬细胞已成为主要的细胞类型。脯氨酸和氨基葡萄糖含量在第7天显著增加,第21天达到最高值。脯氨酸在PTRC中的掺入量显著增加,在第5天达到峰值,第10天开始下降。葡萄糖胺掺入在第7天达到峰值,然后在第10天下降。总之,PTRC中葡萄糖胺和脯氨酸掺入的增加与主要由巨噬细胞组成的PEC的增加平行。这些发现表明,分析腹膜活化巨噬细胞的代谢活动可能为解剖术后腹膜再上皮化的中枢调解提供有用的工具。

A rare case of esophageal carcinoma metastasizing to early gastric cancer is reported herein. 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.

A rare case of an extrathoracic giant hematoma developing after a thoracoplasty in a 67 year old man is presented herein. The patient underwent a right thoracoplasty without removal of plombage and a left thoracoplasty with removal of plombage for tuberculosis of the bilateral upper lobes 27 and 24 years prior to presentation, respectively. He presented to us in May, 1987, with a subscapular tumor which had been growing over the last 5 years. A giant tumor, measuring 23 x 17 x 12 cm and weighing 2585 g was successfully removed and the patient has since been well without any evidence of recurrence.

A fresh surgical specimen from colon carcinoma was tested by the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H tetrazolium bromide assay (MTT assay) and transplanted into nude mice. After 5 transfers in male BALB/c nude mice, the xenograft was then tested again by the MTT assay. It was found that the in vivo chemosensitivity pattern of the xenograft was essentially identical to that of the in vitro fresh surgical specimen, whereas the sensitivity of the xenograft was increased. To exclude the stromal cells from the nude mouse, anti-BALB/c serum was added to the primarily cultured colon carcinoma xenograft, and its chemosensitivity to mitomycin C (MMC) assessed. Although the sensitivity of the serum-treated group to MMC was slightly higher than that of the untreated group, the dose-response curves of the tumor cells to MMC were similar to each other. Thus, the chemosensitivity pattern of tumor cells seemed to be stable with or without normal cells, although the sensitivity itself was reduced by the presence of normal cells.

A rare case of the segmental type of primary sclerosing cholangitis (PSC) is reported herein. A 27 year old Japanese man with obstructive jaundice was referred to our hospital with a provisional diagnosis of bile duct cancer at the hepatic hilum. A PTCD tube had been inserted from the right anterior segmental duct and direct cholangiograms showed complete obstruction of the bile duct at the confluence of the right and left hepatic ducts. Resection of the extrahepatic bile duct and partial hepatectomy were thus performed, however, the postoperative histological examination revealed no malignant features. Instead, the lesion was shown to be compatible with PSC microscopically. A diagnosis of PSC was finally established on the basis of clinical features, cholangiographic appearance and the pathological report.

Liver abscess is a rare complication of Crohn's disease and in most of the reported cases, the diagnosis of Crohn's disease preceded that of liver abscess. We report herein a case in which a liver abscess was the initial clinical manifestation of Crohn's disease in a 36 year old man who presented with high fever and weakness. The diagnosis of liver abscess was established by abdominal ultrasonography, computed tomography and an arterial blood culture. The abscess was resolved with antibiotic therapy alone and during the drug therapy, a barium enema examination was performed which revealed a stricture at the transverse colon. Resection of the transverse colon was performed and macroscopic and microscopic examination of the resected specimen established the diagnosis of Crohn's disease. The liver abscess was thus speculated to be secondary to the inflamed bowel. Although rare, Crohn's disease should be included in the differential diagnosis of diseases causing liver abscess.

It is widely accepted that patients with aortic aneurysm (AA) show a higher incidence of peptic ulcers than those without. 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.

Two cases of ulcerative colitis with a positive Coombs test are reported herein. In a 30 year old woman, hemolytic anemia was well controlled by excision of a rectal stump left over from a former operation. A 53 year old woman had a positive Coombs test without clinical hemolytic anemia 10 years after undergoing a total procto-colectomy with ileo-anal anastomosis. Thus we concluded that total procto-colectomy may be preventive, as well as therapeutic, for Coombs positive hemolytic anemia associated with ulcerative colitis.
