We investigated the presence of K-ras gene mutation in plasma DNA and assessed its clinical value in patients with pancreatic adenocarcinoma. Mutations in codon 12 of the K-ras gene were examined by mutant allele-specific amplification method using DNA extracted from surgical specimens and plasma samples of 21 patients with pancreatic adenocarcinoma. K-ras(More)
Postoperative serum interleukin-6 (SIL-6) and C-reactive protein (SCRP) levels were examined in 71 patients who underwent various types of abdominal surgery. Similar time-dependent changes in SIL-6 and SCRP levels were observed in 12 patients despite differences in surgical procedures and liver function among the patients. SIL-6 started to increase within 3(More)
PURPOSE The aim of this study was to clarify the usefulness of staging laparoscopy for planning the treatment strategy in patients with advanced gastric cancer. METHODS This was a retrospective study of patients with gastric cancer who underwent staging laparoscopy. The patients were divided into three groups according to the presence/absence of(More)
PURPOSE Although hepatic arterial infusion (HAI) is widely performed as a prophylactic chemotherapy for patients who have undergone a curative resection of a metastatic liver tumor from colorectal cancer, the optimal management of implantable ports and catheters after the cessation of such adjuvant therapy remains to be elucidated. METHODS The survival(More)
We report the successful application of a hybrid artificial pancreas device for the treatment of severe diabetes mellitus induced by total pancreatectomy in two dogs. Control of the blood sugar was achieved for more than 1 year in these two animals without any immunosuppressive therapy. Although exogenous insulin was required therapy. Although exogenous(More)
In this study, we examined the effect of mitomycin C (MMC) treatment on graft survival and evaluated its efficacy in immunomodulation of islet graft for transplantation. Male WS rats were used as islet donors and streptozotocin-induced diabetic C57BL/6 mice as recipients. The isolated islets were treated with MMC at concentrations of 0, 0.1, 1, 3.2, 10, 32,(More)
BACKGROUND Greater than 50% of patients who undergo curative resection of liver metastases from colorectal carcinoma develop recurrent disease in the residual liver. Although several studies have attempted to use hepatic arterial infusion (HAI) chemotherapy to prevent recurrence, to the authors' knowledge the efficacy of the treatment has not yet been(More)
In an attempt to develop an improved method for preserving the pancreas prior to islet isolation, the effects of warm and cold ischemia were examined on rat pancreases, from which reproducible high yields of islets can be obtained when fresh. Both warm and cold preservation rapidly decreased islet yield. Use of Hanks' or modified Sacks' solution also led to(More)
CONTEXT Postoperative endocrine and exocrine insufficiencies following traditional pancreatectomies might cause a deterioration of the quality of life and surgical outcome. Parenchyma-sparing pancreatectomies have been utilized in benign lesions and low-grade malignancies. CASE REPORT A 67-year-old female with a past history of right nephrectomy for renal(More)
Although chronic immunosuppression has been extremely successful in clinical organ transplantation, it is associated with severe complications such as opportunistic infections, spontaneous neoplasms, drug toxicities, metabolic complications, and the inability to control rejection. We therefore have investigated the ability of allogeneic donor lymphoid cells(More)
