COMPUTED TOMOGRAPHIC IMAGING OF INFILTRATIVE LIPOMA IN 22 DOGS     

Margaret C.  McEntee  DVM  Donald E.  Thrall  DVM  PhD 《Veterinary radiology & ultrasound》2001,42(3):221-225

Twenty two dogs with an infiltrative lipoma had computed tomographic (CT) images acquired to evaluate the extent of local disease. Ten dogs had undergone at least one cytoreductive surgical procedure (range = 1-3; median = 2) prior to imaging. Twenty dogs had measurable disease on CT images; 2 dogs had diffuse disease at a previous surgical site that could not be measured. Tumor volume (n = 20) ranged from 20 to 5,632 cm3 (median = 345 cm3; mean = 996 cm3). None of the dogs had evidence of bone involvement on the CT images; 2 of the 22 dogs had tumors that did not come into direct contact with osseous structures. All dogs with measurable disease had evidence of a fat opacity mass with variable degrees of muscle infiltration. Eleven of 22 dogs were given intravenous contrast medium prior to image acquisition and there was not evidence of enhancement of the infiltrative lipoma in any dog. Based on CT images, tumors were classified as well-defined in 9 dogs, moderately well-defined in 4, not well-defined in 3 and a mix of well-defined and not well-defined in 6 dogs. Tumors tended to be less well-defined in regions where the infiltrative lipoma interdigitated with normal body fat. It appears CT imaging allows adequate discrimination of tumor with the caveat that differentiation of normal fat from infiltrative lipoma can be problematic.  相似文献

山区农业面源污染的防治途径及对策     

喻尚其刘光德  李其林赵中金 《四川畜牧兽医学院学报》2005,3(4):1-4

结合重庆市地形地貌特点和山区农业面源污染发生的因子，提出山区农业面源污染的防治对策。一方面必需结合当地的自然环境条件和经济发展水平提出农业面源污染的防治规划；另一方面必需结合生态农业建设这一主线，使物质、能量在生态系统内良性循环。紧紧抓住产生农业面源污染源的因子——化肥、农药、农田秸杆、畜禽粪便、农村生活废物等，提出科学的防治和减少途径。  相似文献
