Successful management of otitis externa requires recognition of changes in the anatomy and physiology of the external and middle ear, as well as the adequate tools and examinations to detect changes from normal. Otoscopy and methods for assessing the normalcy of the tympanum, collection of samples for cytologic evaluation or culture, and myringotomy are diagnostic techniques important in practice. Treatment tubes and intralesional triamcinolone injections are techniques that improve the response in some cases.  相似文献

国际上,动物营养学界正在对母猪饲粮中氨基酸营养研究进行回顾。虽然也正在推出保育期及肥育后期猪的氨基酸需要量或供给量建议,但无疑与怀孕母猪氨基酸营养有关的综述最为重要。各地的饲料配方师面临的形势是:当代母猪显然要比仅仅几年前的母猪产仔数更多,泌乳量也更多。这必然意味着它们的氨基酸需要量也明显不同。不过,用于估测氨基酸需要量的方法仍有待改进。  相似文献
