This report describes a simple electronic device employing a piezoelectric element which serves as a sensitive detector of motion. The device is useful as a monitor of respiratory motion for nuclear magnetic resonance animal experiments in vivo. It can also provide a trigger pulse for respiratory gating experiments. 相似文献

It is well known that bioincompatible peritoneal dialysate plays a central role in the development of peritoneal fibrosis. Peritoneal inflammation continues even after the cessation of peritoneal dialysate stimulation. It is important to establish the definition of persistent inflammation in the peritoneal cavity at the cessation of peritoneal dialysis (PD). The objective of the present study was to determine whether pentraxin 3 (PTX3) in peritoneal effluent (PE) may be a new biomarker in PD patients. Serum, PE, and peritoneal specimens were obtained from 50 patients with end-stage kidney disease at Juntendo University Hospital. Samples of 19 patients were obtained at the initiation of PD and those of 31 patients at the cessation of PD. PTX3, high-sensitivity CRP, and MMP-2 and IL-6 were analyzed. An immunohistological examination using an anti-PTX3 antibody was performed. Expressions of PTX3 were observed in endothelial cells, fibroblasts, and mesothelial cells in the peritoneum. The PTX3 level in PE at the cessation of PD was significantly higher than that at the initiation of PD. Effluent PTX3 levels in patients with a history of peritonitis or a PD duration of more than 8 years were significantly higher than those in patients without peritonitis or patients with a PD duration of <8 years. The PTX3 level was significantly correlated with MMP-2 and IL-6 levels in PE, as well as the thickness of the submesothelial compact zone and the vasculopathy. It appears that PTX3 may be a new biomarker of peritoneal inflammation and progressive fibrosis. 相似文献

Upper gastrointestinal endoscopy of a 25‐year‐old man with heartburn revealed an elevated lesion in the esophagogastric junction (EGJ). Piecemeal endoscopic mucosal resection (EMR) followed by histopathological examination led to a diagnosis of inflammatory fibroid polyp (IFP). After EMR, the heartburn persisted despite giving a proton pump inhibitor (PPI), and the residual lesion gradually enlarged and a transverse mucosal break developed on the esophageal side of it. However, the combined administration of the PPI and an H2 receptor antagonist reduced the heartburn, and led to endoscopic regression of the lesion and disappearance of the transverse mucosal break. IFP of the esophagogastric junction is extremely rare, and this case is interesting in that potent inhibition of gastric acid secretion resulted in the regression of the lesion. 相似文献

Perfluorodecanoic acid (PFDA) is a potent peroxisome proliferator that causes hepatotoxicity but lacks tumor-promoting activity in rats. We previously showed that a single dose of PFDA at 50 mg/kg (approximately LD50) causes an elevation in liver phosphocholine (PCho) and other effects related to phospholipid metabolism. In this study, we examined metabolic effects in the dose range 2-50 mg/kg in rats. At doses < or =20 mg/kg, PFDA is significantly less hepatotoxic than the LD50 as manifested by electron microscopy and measurements of daily food consumption and body weight. At 50 mg/kg rat serum tumor necrosis factor (TNF)-alpha concentration was increased 8-fold, while at 15 mg/kg there was no apparent increase in this cytokine. This lower dose, however, induces metabolic effects similar to those seen at the LD50. Liver fatty acyl-CoA oxidase activity showed a dose-dependent increase from 5-25 mg/kg PFDA. Treatments at 15 and 50 mg/kg caused a significant increase in liver phosphatidylcholine (28 and 66%) and phosphatidylethanolamine (31 and 74%). Both doses caused a significant increase in liver PCho but did not affect liver ATP levels, as manifested in 31P nuclear magnetic resonance (NMR) spectra from rat livers in vivo. These data suggest that the increase in liver [PCho] observed following PFDA exposure in rats represents a specific metabolic response, rather than a broad-range hepatotoxic effect. 相似文献
