犬椎间盘突出症又称椎间盘脱位,是由椎间盘变性,压迫脊髓或脊神经而引起后驱感觉和运动障碍等为特征的一种脊椎疾病. 1 病因及机理

肠套叠是指某一段肠管进入相邻的一段肠管内,致使肠管发生不完全或完全阻塞的一种疝痛性疾病,2～6月龄幼犬常见.临床表现以精神沉郁、呕吐、弓背、厌食和腹部触诊敏感为主要特征.笔者在临床实践中遇到1例2月龄的洛特幼犬肠套叠的病例,经过手术治疗后,继发直肠脱.现将治疗情况报告如下.

椎间盘突出症(protrution or herniation of the lumbar intervertbral discs)又叫椎间盘脱位(dislocation of the lumbar intervertbral discs),是由于椎间盘变性,其纤维环局限性膨出或髓核经破裂的纤维环突出,压迫脊髓或脊神经而引起的以后驱感觉和运动障碍等为特征的一种脊椎疾病.笔者于2004-2006年在云南农业大学兽医院见习期间,共遇到8例犬椎间盘突出症.现将诊疗体会介绍如下:

In this experiment ,we took the clinic test and ectogenesis test with the louses living on the head and neck of chook by using the Pyrethrum flower powder and Pyrethrum MARC. After bathing in the liquid medicine of 0.05g～6.0 g drug /per chook in half an hour, the chook began to seek food, its feather got dryness and had no abnormal responses; there is no effects with pyrethrum dregs 6g/per chook . The insects reduced on the second day after bathing in the liquid drug 0.3 g flower marc/ per chook; and we found no insect on the second day after bathing in the liquid drug 0.4g flower powder /per chook, no louse had be found unto 14th days, either. The ectogenesis test showed that the imago was more sensitive.
