The presence of certain defects in both cellular and humoral immunity after thermal injury has been established. Likewise, the translocation of enteric bacteria to the mesenteric lymph nodes and to distant organs has also been observed following serious thermal injury. The effects of granulocyte colony-stimulating factor (G-CSF) on bacterial translocation, the small bowel mucosa, and cecal bacterial content were investigated in a rat model of burn wound sepsis in which albino Wistar rats were scalded over 30% of their bodies, after which the lesions were infected by 1×108 colony-forming units (cfu)Pseudomonas aeruginosa. The control group was treated with 5% dextrose solution subcutaneously starting 2 days preburn, while the treatment group received 100μg/kg human G-CSF subcutaneously. On the 4th day post burn all animals were killed to examine the bowel and culture of the mesenteric lymph nodes (MLN), livers, and spleens. No significant differences were observed between the groups regarding the cecal bacterial content and small bowel; however, a difference was seen in the ratio of translocation in the MLN liver and spleen and quantitative MLN cultures. Based on these findings, G-CSF was thus found to be significantly effective in reducing bacterial translocation due to burn wound sepsis.  相似文献

Progressive pseudorheumatoid chondrodysplasia is a rare hereditary disorder. This autosomal recessive condition is characterised by progressive arthropathy and platyspondyly. The symptoms are similar to those of rheumatoid arthritis but synovitis is absent. In this study a patient with inherited progressive pseudorheumatoid chondrodysplasia is presented.  相似文献

Zusammenfassung Die drei wichtigen Inhaltsstoffe von Haschisch, Cannabidiol, Tetrahydrocannabinol und Cannabinol, lassen sich auf vier verschiedenen Kieselgel-Fertigplatten nach Entwicklung mit Toluol und Besprühen mit 0,1% wäßriger Lösung von Fastblue B voneinander trennen. Eine Vorbehandlung der Platten mit Diäthylamin ist erforderlich. Die einzelnen Rf-Werte werden angegeben.  相似文献

The purpose of this study was to investigate the effect of different polishing methods on color stability of posterior, universal and nanohybrid composite resin restorative materials upon exposure to a staining agent. Twenty-five specimens were prepared for each of 5 different composite resins (Filtek Z250, Filtek P60, Quadrant LC, Grandio and Filtek Supreme). Specimens were divided into 5 groups and different polishing procedures, including polishing discs (Pd), polishing discs then diamond polishing paste (PdP), polishing discs then a liquid polishing system (Biscover) (PdB), and combinations of these (PdPB) were used. Unpolished specimens served as the control (C). The specimens were stored for 48 h in a coffee solution. The color of all specimens was measured before and after exposure with a colorimeter, and total color change ∆E*) were calculated. The data were analyzed with a two-way ANOVA and the means were compared by Tukey HSD test (α=0.05). The lowest color difference was observed in the groups PdP and C, while the highest color difference was observed in PdPB, and PdB. When comparing the five different restorative materials, no significant difference was observed between FiltekP60 and FiltekZ250, and these materials demonstrated significantly less color change than Quadrant LC and the nanohybrid materials (Grandio, Filtek Supreme). The posterior (Filtek P60) and universal (Filtek Z250) composite resin restorative materials, which do not contain tetraethyleneglycol dimethacrylate (TEGDMA), were found to be less stainable than the nanohybrid (Grandio, Filtek Supreme) and universal (Quadrant LC) composite resins, which contain TEGDMA. The use of diamond polishing paste after polishing with polishing discs significantly decreased staining when compared to the groups that used polishing discs alone, for all restorative materials tested. The highest color change values were obtained for the specimens that were polished with the Biscover liquid polish system (PdB and PdPB groups).  相似文献

Total intestinal aganglionosis is the rarest form of Hirschsprung's disease, with absence of ganglia from the duodenum to the rectum. In addition to those cases reported in the literature, a neonate with total intestinal aganglionosis with involvement of the stomach is presented. Diagnosis of this extensive form of Hirschsprung's disease is a major problem. These patients lie beyond the scope of present surgical expertise, and the outcome is universally fatal.  相似文献

A 10-year-old-boy with acute acalculous cholecystitis due to polyarteritis nodosa of the gallbladder with limited involvement of this organ is reported. It is suggested that a search for other lesions is indicated when polyarteritis nodosa of the gallbladder has been diagnosed, but that no treatment is indicated when additional lesions are not found.  相似文献

A case of primary hyperoxaluria is presented. In a product of consanguinous marriage recurrent stone formation, nephrocalcinosis and increased urinary oxalate excretion revealed the diagnosis of hyperoxaluria. Diagnosis and treatment of primary hyperoxaluria are briefly reviewed and the importance of elevated urinary oxalate level in diagnosis is emphasized.  相似文献

Intradiploic epidermoid-tumor of the occipital bone was presented. There were neither intracranial extensions nor neurologic deficits. The lesion started as a painless mass under the scalp.The total removal of the tumor was associated with a good prognosis.  相似文献
