Histochemistry on the cervical, thoracic, and abdominal esophageal muscle of immature, young, and adult normal dogs revealed type IIA striated musculature in contrast to some other species. No other types or subtypes were observed. This suggests that esophageal muscle type is established at birth and does not vary or that any variation has been completed by 4 weeks-of-age unlike some canine limb musculature. 相似文献

Urethrotomy was performed on 12 normal male dogs at the base of the os penis. The surgical site was allowed to heal by second intention in six dogs, and suture closure of the urethral mucosa, tunica albuginea, and subcuticular tissue was performed in six dogs. All dogs were maintained for 60 days postoperatively. Packed cell volume and serum total protein were measured before surgery and at 2, 4, 7, 14, and 60 days postoperatively. Suture closure of the urethra resulted in less hemorrhage during the postoperative recovery period. Urethral mucosal irregularity was seen in urethrograms performed on all operated dogs 60 days postoperatively. Urethral stricture was not observed in any of the dogs in this study. 相似文献

为了研究脂肪干细胞(Adipose-derived stem cells,ASCs)体外培养方法及其生物学特性,将ASCs应用于小动物临床治疗,本试验用犬进行了脂肪干细胞的分离、培养和鉴定。犬脂肪干细胞(Canine adipose-derived stem cells,cASCs)体外培养生长良好,呈细长梭形。第3代(P3)细胞诱导2周后,成脂诱导组经油红O染色可见细胞内脂滴积累;成骨诱导组经碱性磷酸酶(Alkalinephosphatase,AKP)及VonKossa染色,AKP、钙结节均呈阳性表达。第3代至第5代(P3P5)细胞流式细胞检测结果显示,所分离细胞稳定高表达间充质干细胞(MesenchymalStem Cells,MSCs)标志CD29、CD44、CD90(>90%),不表达造血细胞标志CD45(<2%)。培养结果显示,从犬镰状韧带和皮下脂肪均可分离出cASCs。cASCs取材方便,易于体外培养,多次传代及冻存对cASCs的生物学性质无明显影响。eASCs有望成为国内动物医学临床研究和治疗的重要干细胞来源。 相似文献

为寻找免疫失败的原因,有效防治犬瘟热的流行,对临床一水貂犬瘟热疑似病例,取其肝、脾、脑等组织研磨后接种Vero和BHK细胞分离病毒,并对分离毒株进行一系列鉴定。通过电镜观察,发现了大小约150 nm的副黏病毒样粒子。结果表明,分离株对鹅、鸡、小鼠、家兔、山羊、猪红细胞均无凝集性,该分离株的毒价TCID50为10-4.87;分离株病毒对乙醚、氯仿敏感,病毒的核酸型为RNA。经间接免疫荧光试验,接种病毒的BHK细胞出现特异性的亮绿色荧光。对分离株和对照毒株分别提取RNA进行RT-PCR扩增,最后得到与预期扩增片段(294 bp)相符的核酸电泳带,充分证明分离病毒为犬瘟热病毒。 相似文献

The results from a recent study by Bruce and Schurg (1990) indicate that the gluteus medius (Gm) of the horse is a complex muscle subdivided by an internal tendinous sheet into two regions (dorsal and ventral) which may subserve different functions. In the present study, both regions were found to contain a similar proportion of histochemically-determined muscle fibre types. Fibre type composition did not generally vary over the length of the muscle at the same relative depth. In contrast, there was a significant tendency for the percentage of type I fibres to increase gradually in accordance with depth. These histochemical results do not suggest that the two regions of the Gm assume distinct functional roles; they do, however, indicate that at a given relative depth the muscle fibre type distribution is relatively uniform over the length of the muscle. Nevertheless, care should be exercised in sampling and interpreting data obtained from limited biopsy of equine Gm, due to the substantial histochemical variation of fibre type compositon as a function of sampling depth. 相似文献

犬尿路结石在徐州地区发病较高,并且复发率较高,给家庭养犬业造成了极大的影响。犬尿路结石主要发生于老龄公犬,笔者最近在临床上接诊一例复杂的母犬膀胱尿道结石病例,尤其尿道结石较大,处理起来非常困难,最后采用尿道口切开术,将结石顺利取出。犬尿路结石的手术疗法国内一般采用膀胱切开术和尿道切开术,采用尿道口切开术尚属首例。 相似文献

This article provides a brief review of human episcleritis and scleritis, because the pathogenesis, diagnosis, and treatment of these disorders are perhaps the best understood of all species of animals. The clinical and light microscopic manifestations, therapeutic options, and prognosis for primary and secondary episcleritis and scleritis in dog are also reviewed. The focus of this article is on primary and secondary inflammatory conditions that originate in the episclera and sclera caused by idiopathic or known etiologies. 相似文献
