In Kobe University Hospital, a new method for endoscopic mucosal resection (EMR) using insulated‐tip electrosurgical knife (IT‐EMR) for early gastric cancer (EGC) was introduced from November 2001. To achieve an effective and safe IT‐EMR procedure, we use a high‐frequency surgical unit for cutting and coagulation (ERBOTOM ICC 200) with automatically controlled cutting mode (ENDOCUT). In this study, we show not only our results of IT‐EMR for EGC in comparison with those of the conventional strip biopsy method, but also the optimal conditions for the apparatus of a high‐frequency surgical unit to prevent complications such as bleeding and perforation. 相似文献

We report a rare case of granulomatous balanoposthitis after intravesical Bacillus-Calmette-Guerin (BCG) instillation therapy in a 58-year-old man, which followed transurethral resection (TUR) for recurrent bladder cancer, when his anterior urethra was slightly narrow and his foreskin was with phimosis. Intravesical BCG instillation therapy was started for prophylaxis of recurrent bladder cancer after TUR. Multiple painless firm papules on glans penis, edema in the foreskin and low-grade fever appeared after the seventh instillation, for which the single antituberculous agent isoniazid (300 mg/day) was administered. Biopsy of the papules on glans penis and foreskin revealed granulomatous balanoposthitis. Low-grade fever normalized and the papules disappeared within 1 week. The patient continued chemotherapy with isoniazid for the next 12 months. There was no recurrence of bladder cancer or balanoposthitis for 15 months and to date. 相似文献

Laparoscopic cystectomy and bilateral ureteric ligation were performed on a 52-year-old woman with end-stage renal disease on hemodialysis (HD) for muscle-invasive bladder cancer. Her volume of urine production was approximately 100 mL/day. Excisions of the bladder and uterus with ligation of the bilateral ureter were conducted completely laparoscopically. Total operative time was 280 min and the amount of blood loss was 60 mL. No complications were seen perioperatively and no adverse events regarding ureteric ligation arose. HD was performed on the second postoperative day. At a 12-month follow-up, the patient showed no evidence of disease. 相似文献

Abstract This study investigated interactions between mucosal lesions and bacterial invasion in ulcerative colitis using the acridine-orange staining method. In all 16 cases of ulcerative colitis, the mucosa was found to be invaded by small rods and cocci. In five of 10 controls, bacteria were seen only adhering to the mucosa and no bacteria were detected in the five remaining cases. It is suggested that the presence of bacteria in the colonic mucosa may be a factor responsible for the persistence or aggravation of ulcerative colitis. 相似文献

In 45 healthy Japanese volunteers, it was found that personsheterozygous for ALDH2 (ALDH2*1/ALDH2*2), and also either heterozygousor mutant homozygous for CYP2E1 (C2/C2 or C1/C2 can drink muchmore alcohol, even with (slight) flushing, than persons heterozygousfor ALDH2 (ALDH2*1/ALDH2*2) and normal homozygous for CYP2E1(C1/C1) 相似文献

The human monoclonal antibody against cytomegalovinis (Mab C23)was examined pharmacokinetically and toxicologically as partof the preclinical studies prior to approval for human use.Rats given repeated intravenous administrations of Mab C23 producedno antibodies against Mab C23 and maintained a blood Mab C23level in a dose-dependent manner. However, pregnant rabbitsproduced antibodies against Mab C23. The half-life of Mab C23in plasma was 15.9 days in rats, which was similar to that ofnormal human serum -globulin (NHSG). Neither behavioral effectsnor circulatory disturbance was found in mice, rats, and dogseven after a single intravenous injection of 100 or 200 mg/kg,which corresponds to 50 or 100 times the intended clinical dosage.The repeated doses of 2, 10, or 20 mg/kg of Mab C23 on six occasionswith 1- or 2-week intervals elicited a transient decrease inleukocyte counts in rats given 10 or 20 mg/kg, but no adverseeffects in cynomolgus monkeys. Mab C23 did not cause any reproductiveor developmental toxicity when administered to rats and rabbitsat dose levels of 20 mg/kg or less. However, pregnant animalsshowed lower plasma levels of Mab C23 than non-pregnant animals.The chromosomal aberration test disclosed no clastogenicityin human lymphocytes. An immunostaining for Mab C23 revealedno localizations in several tissues of cynomolgus monkeys givenintravenous doses of Mab C23. The preclinical safety evaluationin animals other than rabbits, which produced no antibodiesagainst Mab C23, showed that the behavior of Mab C23 is pharmacokineticallysimilar to that of NHSG and is as safe as NHSG, which has longbeen used as a biological agent. However, because there wasa difference in blood levels of Mab C23 between pregnant andnonpregnant animals, its clinical administration to pregnantpatients should differ from that to non-pregnant patients. 相似文献

The object of this study was to determine the frequency and characteristics of altered paraumbilical vein in the hepatic parenchyma, developed from portal hypertension, using computed tomography (CT). Two hundred and ninety-two patients who presented with portal hypertension from 1986 to 1996 were studied retrospectively. The pathway of the dilated para-umbilical vein was demonstrated by contrast-enhanced CT. Thirty-one (11%) patients had a dilated para-umbilical vein arising from the left portal vein into the falciform ligament. In 24 (77%) of these patients, the para-umbilical vein followed the expected route, passing through the fissure of ligamentum teres hepatis. The remaining seven patients (23%) displayed the unusual pathway, with the vein arising from the left branch of the portal vein and passing into the hepatic parenchyma. In these seven patients, four had one collateral vein, and three patients had two collateral veins in the liver parenchyma. The dilated para-umbilical vein frequently passes through the hepatic parenchyma in patients with portal hypertension. 相似文献

Background and objective: Bronchiolitis obliterans (BO) has been reported to develop following ingestion of Sauropus androgynus (SA), a leafy shrub distributed in Southeast Asia. Little is known about direct effects of SA on airway resident cells or haematopoietic cells in vitro. Identification of the SA component responsible for the development of BO would be an important key to elucidate its mechanism. We sought to elucidate the direct effects of SA on airway resident cells or haematopoietic cells and identify the SA element responsible for the pathogenesis of BO. Methods: SA dry powder was partitioned into fractions by solvent extraction. Human and murine monocytic cells, epithelial cells and endothelial cells were cultured with SA solution or fractions eluted from SA. We also investigated the effect of SA in vivo using a murine BO syndrome (BOS) model. Results: The aqueous fraction of SA induced significant increases of inflammatory cytokine and chemokine production from monocytic lineage cells. This fraction also induced significant apoptosis of endothelial cells and enhanced intraluminal obstructive fibrosis in allogeneic trachea allograft in the murine BOS model. We found individual differences in tumour necrosis factor α (TNF‐α) production from monocytes of healthy controls stimulated by this aqueous fraction of SA, whereas it induced high‐level TNF‐α production from monocytes of patients with SA‐induced BO. Conclusions: These results suggest that an aqueous fraction of SA may be responsible for the pathogenesis of BO. 相似文献

The effects of peroxovanadate or tungstate on 3-O-methylglucose uptake were characterized using isolated rat adipocytes to elucidate the mechanism(s) of their actions. The stimulatory effect of peroxovanadate was observed from 1 μmol/L and reached the maximum at about 100 μmol/L. The concentration showing the half-maximal effect was approximately 16 μmol/L. The maximal response of peroxovanadate was 1.19 times higher than that of insulin significantly (P < 0.01). On the other hand, the stimulatory effect of tungstate was seen only at the higher concentrations of 10–30 mmol/L Judging from the experiments using different tungsten compounds, tungstic acid (WO42-) appeared responsible for the effect. The effects of 20 mmol/L tungstate and 20 nmol/L insulin were not additive. The stimulatory effects of 1 mmol/L peroxovanadate, 20 mmol/L tungstate or 20 nmol/L insulin were not seen in the adipocytes deprived of ATP by exposure to 2 mmol/L KCN. The adipocytes which had been stimulated with insulin and further exposed to 2 mmol/L KCN were used to test whether or not peroxovanadate works directly on the function of glucose transporters. In such cells on which GLUT4-rich transporters were rendered immobile, the effect of peroxovanadate was not observed. These results indicate that the effects of peroxovanadate or tungstate are ATP or energy dependent and may be exerted through the mechanism analogous to that of insulin action, and suggest that peroxovanadate does not directly activate the function of GLUT4. 相似文献
