鸡尿液收集方法及其理化指标和尿沉渣的研究

对 2 0羽 45日龄伊沙蛋雏鸡进行结肠造口术 ,收集 2 4h的尿液及尿沉渣 ,并对鸡尿液的理化指标及尿沉渣进行分析研究。结果显示 :鸡的尿液呈淡黄色 ,并有稠粘液体性质 ,鸡的尿量为 :(37 34± 8 0 0 )mL ,尿液pH值为 6 58± 0 32 ,尿密度为 1 0 1 8± 0 0 0 9,尿酸为 (398 951±51 2 91 ) μmol/L ,钙为 (5 580± 0 2 4 1 )mmol/L ,无机磷为 (1 2 1 7± 0 996)mmol/L ,镁为 (3 735± 0 0 1 0 )mmol/L ,钠为 (1 37 2 50±1 3 789)mmol/L ,钾为 (41 81 0± 1 887)mmol/L。扫描电镜下 ,尿沉渣中球形物较多 ,混有少量的针状晶体 ,表明主要含尿酸盐。能谱分析表明 ,上述结构的主要组成元素为钙、钾及少量的镁和钠     

Permanent colostomy after small colon prolapse in a parturient mare

Small colon prolapse is a possible complication during parturition and diarrhoea. A case diagnosed in a mare during birth labour was reduced by the attending veterinarian at the farm, and referred to the authors for evaluation. After thorough physical examination, blood and peritoneal fluid tests, a ruptured mesocolon was suspected and the mare explored under general anaesthesia by a median celiotomy approach. During the procedure the affected mesocolon‐rectum was confirmed and a resection of the intestine elected. After prolapsing the segment of damaged viscera a permanent end colostomy was performed. Fourteen months later and after an uneventful recovery, the mare was in a very good physical condition and waiting to be covered for the next breeding season.
