[Validation study on a multi-residue method for determination of pesticide residues in agricultural products by new automatic pretreatment equipment (FASRAC) and GC-MS/MS].

A validation study was performed on a multiresidue method for determination of pesticide residues in agricultural products according to the method validation guideline of the Ministry of Health, Labour and Welfare of Japan. FASRAC (Food Automatic Analytical Systems for Residual Agricultural Chemicals) automatically performs extraction of pesticide residues from agricultural products with acetonitrile, filtration, constant volume, mixing with the use of air, mixing acetonitrile with buffer solvent, separation, and dehydration with sodium sulfate. The extract was purified with a GC/NH2 column.

[A long survival case of sigmoid colon cancer patient with initially unresectable hepatic metastases].

The prognosis of a colorectal cancer patient with unresectable hepatic metastases is extremely poor. To improve the prognosis, when the hepatic metastases were initially unresectable, we performed second-look hepatectomy (s-l hepatectomy) after neoadjuvant hepatic arterial 5-FU infusion plus UFT (HAI-PMC). Here, we report the case of a sigmoid colon cancer patient with initially unresectable hepatic metastases showing a prolonged survival (6.

Anal function during pregnancy and postpartum after ileal pouch anal anastomosis for ulcerative colitis.

Purpose: Total proctocolectomy and ileal pouch anal anastomosis (IPAA) is now a common procedure for ulcerative colitis (UC). Moreover, it has been reported that fertility is preserved in women who undergo this procedure, many of whom can experience normal delivery.

Methods: We assessed the perinatal outcomes and changes in anal function in four women, aged from 27 to 35 years, who gave birth after undergoing IPAA for UC.

Effect of lateral cyclic loading on abutment screw loosening of an external hexagon implant system.

Statement Of Problem: Efforts to reduce the recurrence of abutment screw loosening with single tooth implant-supported restorations have been reported. However, the current knowledge about the role of the implant external hexagon is incomplete.

Purpose: This in vitro study investigated the effect of lateral cyclic loading with different load positions on abutment screw loosening of an external hexagon implant system.

New reconstructive procedure after intestinal resection for Crohn's disease: modified side-to-side isoperistaltic anastomosis with double Heineke-Mikulicz procedure.

Although side-to-side isoperistaltic anastomosis is a useful strictureplasty technique when long segments of intestinal stenosis complicate Crohn's disease, concerns have been raised regarding disease recurrence adjacent to the anastomosis. We performed side-to-side isoperistaltic anastomosis without spatulated intestinal ends as a method of reconstruction after intestinal resection for Crohn's disease; both intestinal ends were transversely closed like a Heineke-Mikulicz-type strictureplasty. With this procedure, the luminal diameter proximal and distal to the anastomosis became wider than the original diameter of the intestine.

Effect of intra-arterial cisplatin on multiple liver metastases from rectal cancer associated with ulcerative colitis.

We report a patient with synchronous multiple liver metastases from rectal cancer associated with ulcerative colitis. Because the liver tumors were unresectable, we performed total proctocolectomy and hepatic intra-arterial cisplatin infusion with systemic oral administration of fluorouracil. A complete response was obtained.

Octreotide in control of multiple liver metastases from gastrinoma.

The somatostatin analogue octreotide was effective in controlling systemic effects related to multiple liver metastases from a gastrinoma. A 61-year-old man underwent distal gastrectomy for gastrinoma in the duodenum, because a curative resection was not feasible due to metastases found in paraaortic lymph nodes during operation. Multiple liver metastases, associated with an increase in serum gastrin concentration, were found by magnetic resonance imaging 16 months after the operation.

Measurement of phosphatidylcholine hydroperoxide in mild ischemia-reperfusion injury in rat intestine.

In the pathogenesis of intestinal ischemia-reperfusion injury, the measurement of lipid peroxides needs to be established. Sprague-Dawley rat intestines were assessed after 30 minutes of occlusion of the superior mesenteric artery followed by reperfusion at 30, 60, 120, 180, 360 minutes. Grade of the mucosal injury, accumulation of the activated neutrophils and ICAM-1 expression were transiently increased after reperfusion.

Surgical treatment of chronic intestinal pseudo-obstruction: report of three cases.

We report the cases of three patients with chronic intestinal pseudo-obstruction (CIP) whose quality of life (QOL) was improved by palliative surgery in combination with home parenteral nutrition (HPN). Loop enterostomy and shortening of the gastrointestinal tract was performed with good results in all three patients to relieve abdominal distension that was progressive despite treatment with prokinetic drugs. Oral intake was also improved after surgical treatment in one patient who underwent massive resection of the jejunoileum.

Formation of Embryo Thromboblasts in Chick Blastoderm: Morphology, Site of Production and Time of Emergence in the Blood: (embryo thromboblast/glycogen deposit/differentiation/chick blastoderm).

Thrombocytes in the blood of chick embryos (termed embryo thrombocytes by Lucas and Jamroz) have PAS-positive granules in their cytoplasm. Electron microscopic observations reveal that the embryo thrombocytes contain glycogen granules present singly or in clumps. The presence of these inclusions and other morphological characteristics were used as specific markers to distinguish embryo thrombocytes from primitive erythroid cells.
