PURPOSE: Our objective was to evaluate the feasibility of early resumption of ambulation 3 hours after transfemoral angiography using a 4 French sheath. SUBJECTS AND METHODS: This prospective study was carried out in a selected group of men and women without impaired blood clotting (prothrombin time > 15 sec) or thrombocytopenia (platelet < 55,000/mm3). The subjects consisted of 66 men and 34 women with a mean age of 62.3 years (range 27-90 years). Incidences of rebleeding or hematoma at the site of femoral catheter insertion were investigated before and after ambulation. Rebleeding was defined as bleeding that required recompression. Hematoma was defined as a palpable, firm collection of subcutaneous blood. RESULTS: Of 100 patients who resumed full ambulation after three hours of bed rest, none (0%) had acute groin hematoma and only three (3%) showed rebleeding that had to be manually compressed. The remaining 97 patients (97%) had no problem after ambulation. CONCLUSION: Supervised resumption of ambulation 3 hours after angiography with a 4 French sheath is safe and feasible in most ambulatory patients undergoing transfemoral angiography. 相似文献

The CD57(+)HLA-DR(bright) natural suppressor (57.DR-NS) cell line derived from human decidual tissue mediated apoptosis of human leukemia Molt4 and carcinoma BeWo/GCIY cells but not human fibroblast WI-38 cells, and apoptosis-inducing nucleosides (AINs) appeared to be involved. Six AINs were released into 57.DR-NS cell culture media and were isolated by the combination of physicochemical procedures of C18 preparative column, thin layer chromatography (TLC) and high pressure liquid chromatography (HPLC). Subsequently, we demonstrated that AINs could induce apoptosis in the human malignant Molt4/BeWo/GCIY cell line but not human normal WI-38 fibroblasts. Apoptosis was characterized by DNA strand breaks and activation of the caspase cascade, especially caspase-3. The administration of AINs into GCIY tumor bearing SCID mice culminated in suppression of tumor growth due to apoptosis of tumor cells. 相似文献

Abstract: SSP-PCR (sequence-specific primer) DNA typing was performed in Terasaki trays using 1.5 μ1 of DNA, and the ethidium-stained PCR product was measured by direct fluorometric reading. Elimination of the gel electrophoresis step greatly simplified the SSP method. 17 serological DR specificities were discriminated for 239 DNA samples utilizing the new method, standard SSP, sequence-specific oligonucleotide probe (SSOP), and restriction fragment length polymorphism (PCR-RFLP). Results showed 98% concordance between the SSP-PCR assay and conventional methods. DRB1 alleles were determined by PCR-RFLP in 59 samples, by SSP in 110 samples, and by consensus (all methods) in the remaining samples. 相似文献

The epimerization rate constants of R- and S-epimers of moxalactam (LMOX) in a frozen aqueous solution decreased as the temperature decreased. The reaction proceeded in the unfrozen region remaining in the frozen solution, without being affected by the ice. The reaction stopped completely below the collapse temperature of the LMOX aqueous solution. The ratio of R- and S-epimers at equilibrium, which was equal to the ratio of the epimerization rate constant, increased as the temperature decreased. This change in the ratio at equilibrium could be ascribed to the difference in the activation energy between the two epimers. 相似文献

OBJECTIVES: This study investigates renal dysfunction in areas without known environmental cadmium pollution and calculates the threshold level of urinary cadmium. METHODS: Urinary total protein, beta2-microglobulin (beta2-MG), and N-acetyl-beta-D-glucosaminidase (NAG), used as indicators of renal dysfunction, and urinary cadmium concentration, used as an indicator of cadmium exposure, were measured in two sets of 24-hour urine samples from each of 828 participants (410 men, 418 women), aged 40-59 years and living in three areas without any known environmental cadmium pollution. In multiple regression and logistic regression analyses the association between indicators of cadmium exposure and indicators of renal dysfunction were studied. The lower 95% confidence limit of the dose (benchmark dose) corresponding to a 5% (BMDL5) or 10% (BMDL10) level of each indicator of renal dysfunction above the background level) was calculated as the threshold level of urinary cadmium. RESULTS: With all the expressed units [g creatinine(-1) and day(-1)] in the multiple regression analysis, the partial regression coefficients showed a significant association between urinary cadmium concentration and total protein, beta2-MG, and NAG for both genders, except for total protein for women (g creatinine(-1) and day(-1). The same results were obtained for both genders in the logistic regression analysis. The BMDL10 was 0.6-1.2 microg/g creatinine and 0.8-1.6 microg/day for the men and 1.2-3.6 microg/g creatinine, and 0.5-4.7 microg/day for the women. CONCLUSIONS: Cadmium exposure and the levels of the indicators of renal dysfunction were associated among the men and women aged 40-59 years in areas without any known environmental cadmium pollution. The threshold level of urinary cadmium in Japan seems to be almost the same as in Belgium and Sweden. 相似文献

Non-treated homozygous polydactyly/arhinencephaly (Pdn/Pdn) mouse fetuses exhibited exencephaly in 16.7% of cases. Treatment of Pdn/Pdn mice with 350 mg/kg of valproic acid (VPA) on days 8.5 and 9.5 of gestation increased the rate of exencephaly to 66.7%. The responsible gene for the Pdn mouse phenotype has been determined to be Gli3, and the suppression of Gli3 gene expression has been documented in Pdn/Pdn embryos. We investigated how the sonic hedgehog (Shh) and Fgf8 genes, the correlated genes of Gli3, are expressed in the VPA-treated exencephalic Pdn/Pdn embryos on day 10 of gestation, using whole mount in situ hybridization (WISH) and real-time PCR methods. We could not detect any alterations in Shh expression by real-time PCR, or WISH in the non-treated Pdn/Pdn and VPA-treated exencephalic Pdn/Pdn embryos. Altered Fgf8 expression patterns were observed in the commissural plate and dorsal isthmal neuroepithelium in the non-treated Pdn/Pdn embryos. We speculated that the altered expression of Fgf8 might be the result of down-regulation of Gli3 in Pdn/Pdn embryos. Fgf8 gene expression in the commissural plate and dorsal isthmal neuroepithelium exhibits wide or altered signal patterns in the VPA-treated exencephalic Pdn/Pdn embryo. From these findings, it was suggested that down-regulation of Gli3 gene expression induced the altered expression of Fgf8 in the Pdn/Pdn embryos, and that VPA treatment accelerated the alterations of Fgf8 gene expression in the Pdn/Pdn embryos. It was further speculated that altered expression of Fgf8 in the commissural plate may be the fundamental cause of exencephaly, and that the synergistic effect between gene and drug shown in this experiment may explain the differences of sensitivity in the side-effects of the drug. 相似文献

Chronic lithium treatment decreases tau lesions by promoting ubiquitination in a mouse model of tauopathies 总被引:3,自引:2,他引:1

Lithium, a widely used drug for treating affective disorders, is known to inhibit glycogen synthase kinase-3 (GSK-3), which is one of the major tau kinases. Thus, lithium could have therapeutic benefit in neurodegenerative tauopathies by reducing tau hyperphosphorylation. We tested this hypothesis and showed that long-term administration of lithium at relatively low therapeutic concentrations to transgenic mice that recapitulate Alzheimers disease (AD)-like tau pathologies reduces tau lesions, primarily by promoting their ubiquitination rather than by inhibiting tau phosphorylation. These findings suggest novel mechanisms whereby lithium treatment could ameliorate tauopathies including AD. Because lithium also has been shown to reduce the burden of amyloid- pathologies, it is plausible that lithium could reduce the formation of both amyloid plaques and tau tangles, the two pathological hallmarks of AD, and thereby ameliorate the behavioral deficits in AD. 相似文献

BACKGROUND/AIMS: The principle of integral photography was first proposed by Lippman in 1908. Recently, the three-dimensional display system based on the principle of integral photography was developed. It projects three-dimensional objects using a lens array called a fly's eye lens and photographic film. Some groups have used it for surgical navigation in brain surgery. In this study, we tried to generate integral photographic images of intraductal papillary mucinous tumors of the pancreas, and evaluated the feasibility of this method. METHODOLOGY: Five patients with an intraductal papillary mucinous tumor of pancreas were studied. We used MRI data as three-dimensional data. MRI data were acquired with a 1.5-T clinical imager (Signal.5; GE Medical Systems, U.S.A). We used multi-slab single-shot fast spin-echo sequences. Section thickness was between 2 and 3mm in the coronal plane. From these data, integral photographic images were generated on a liquid crystal display by a three-dimensional rendering algorithm. RESULTS: Three-dimensional images using the principle of integral photography could be generated in all 5 cases. We could recognize these images as three-dimensional images by slightly moving the viewpoint to up, down, left, and right. From these images, we were able to grasp the three-dimensional relationship between the tumor, bile duct, and pancreatic duct. Using these three-dimensional images, a variety of minimally invasive surgical procedures were performed for intraductal papillary mucinous tumor of the pancreas, more safely and speedily than formerly. CONCLUSIONS: The images based on integral photography are suitable for medical imaging and are useful for surgical planning. 相似文献
