A 13‐year‐old Romanov sheep presented for evaluation of vaginal discharge, depression and anorexia. Blood work demonstrated mature neutrophilia and marked hyperlactatemia. Transrectal and transabdominal ultrasound revealed echogenic fluid (pus) within the uterus. Purulent uterine fluid culture yield Escherichia coli. A diagnosis of pyometra was made. After medical treatment without clinical improvement, an exploratory laparotomy was performed, and a 360‐degree uterine left horn torsion was identified with the pyometra and multiple corpora lutea on both ovaries. Ovariohysterectomy was performed and the ewe recovered uneventfully. 相似文献

Skeletal Muscle for Endomyocardial Biopsy: Comparable Stress Response in Doxorubicin Cardio-myopathy
In the present study, we compared the cell damage response in skeletal and cardiac muscle tissue when exposed to doxorubicin. This was carried out by means of a less invasive informative substitute to endomyocardiac biopsy based on Hsp70 immunodetection and a subcellular analysis of the nucleolus. Male Sprague Dawley rats (62 g body weight) were randomly distributed into 3 group, the control and doxorubicin I and doxorubicin II groups, in which 15 and 25 mg/kg body weight of doxorubicin (0.1 ml, i.v.) was administered, respectively. After 15, 30, 45 and 60 minutes, portions of the left and right ventricle wall and interventricle wall, together with skeletal muscle from the posterior and anterior member, were prepared for Hsp70 immunodetection by Western blot analysis and ultrastructural study using the thin cut technique. Differential cell response between the control and treated groups was observed in Hsp70 immunodetection and at the subcellular level. In the control group, the Hsp70 recognition levels and typical normal nucleolar morphology were similar, while the treated groups showed variable-dependent Hsp70 recognition and segregation of nucleolar components, forming ring-like figures of a variable-independent nature. Comparison of cardiac and skeletal muscle tissue cell response to doxorubicin toxic aggression revealed parallelism in terms of Hsp70 accumulation in certain regions of both tissues (15 mg/kg body weight of doxorubicin), which suggests that replacing endomyocardiac biopsy analysis with skeletal muscle analysis may be a safe option. 相似文献

[目的]研究日粮中添加薰衣草精油替代饲用抗生素对肉仔鸡生产性能及胴体品质的影响.[方法]将300只1日龄AA肉仔鸡随机分成4个处理组(每组设3个重复,每个重复25只),对照组饲喂基础日粮加抗生素,试验Ⅰ组、Ⅱ组、Ⅲ组日粮为基础日粮,分别添加薰衣草精油0.4、0.8、1.2(0～2周)和0.2、0.4和0.6 mL/kg(3 ～6周).[结果]日粮中添加薰衣草精油与添加抗生素比较,对肉仔鸡的平均日增重、料重比、死淘率和胴体品质等生产性能指标的影响不显著(P＞0.05);除了试验组Ⅲ的腿肌率与抗生素组相比有显著降低外(P＜0.05),其它胴体品质指标与抗生素组相比无显著性差异(P＞0.05).试验组的平均死淘率(0.86;)低于抗生素组的死淘率(3.1;);试验组Ⅰ比抗生素组日增重提高了1.87; (P ＞0.05),料重比降低了0.53; (P ＞0.05).[结论]从肉仔鸡41 d末重、料重比、死淘率等指标综合评定来看,用薰衣草精油替代肉仔鸡饲用抗生素是可行的,0～2周和3～6周日粮中分别添加薰衣草精油0.4和0.2 mL/kg的效果较好. 相似文献
