A computerized method for rapid quantification of gallbladder volume from real-time sonograms 总被引:4,自引:0,他引:4
A computerized method that requires only 1-2 minutes to quantify gallbladder volume from real-time sonograms is described. This time is considerably shorter than that required using the hand-calculation method. There was a highly significant correlation between gallbladder volumes calculated by computer and hand (r = 0.97; P less than .001). 相似文献

阿霉素羧甲基葡聚糖微球犬肝动脉栓塞后阿霉素的体内过程 总被引:4,自引:0,他引:4
研究了阿霉素羧甲基葡聚糖微球经肝动脉栓塞后的体内动力学过程、靶向特征和微球在体内的肝动脉栓塞效果。对犬进行肝动脉栓塞实验,并与肝动脉阿霉素(ADM)溶液灌注组进行对照。用HPLC荧光检测外周静脉和组织中药物浓度。结果表明:微球组峰浓度为0.558μg/ml,溶液组为1.013μg/ml;微球组的T1/2(α),T1/2(β)和MRT分别为溶液组的2.82,3.19和1.28倍。栓塞不同部位组织中ADM浓度,微球组分别是溶液组的8.0和9.1倍。动态血管造影表明:肝内外未见侧枝循环形成,栓塞作用持久,16周后微球仍未见完全降解。 相似文献

Childhood Crohn's disease may cause significant morbidity. T cell activation is considered to be central to Crohn's disease pathology, and as cyclosporin is a powerful inhibitor of T cell activation, and has been used in adult Crohn's disease with encouraging results, it may offer the prospect of remission if given early in the course of disease. Children with newly diagnosed Crohn's disease or those relapsing off treatment were therefore given cyclosporin or conventional treatment (enteral nutrition or corticosteroids) by random allocation. Evaluation was performed initially and at two months. Twenty four children were studied (10 on cyclosporin and 14 on conventional treatment; one child on cyclosporin withdrew). Significant clinical improvement occurred in the group on conventional treatment, but not in the cyclosporin group. Colonoscopic improvement was noted in 5/9 on cyclosporin and 8/14 on conventional treatment, but neither group produced a significant fall in median colonoscopic index. Histological improvement was seen in 7/8 on cyclosporin and 8/13 on conventional treatment, but cyclosporin was not significantly better. Cyclosporin produced improved clinical and histological appearance without matched improvement in blood disease indices. It was not better than conventional treatment, and simple oral administration is probably not suitable for newly diagnosed patients with Crohn's disease. 相似文献
