采用常规实验室检查方法对6头中国荷斯坦奶牛腕关节和跗关节滑液中蛋白质、葡萄糖、钙和磷的含量进行了测定,并与血清中相应成分进行比较分析,结果,左右关节之间无差异,腕关节的总蛋白、白蛋白、球蛋白均比跗关节的低,但差异不显著。血清中的蛋白质、葡萄糖及磷的含量极显著地高于滑液中,只有钙的含量极显著地低于滑液中的含量。 相似文献

在众多的奶牛场中 ,关节疾病占有相当大的比例 ,因其对产乳量有一定的影响而受到重视。关节疾病的发生必然会引起滑液的物理性状和细胞成分的改变。因此 ,研究正常关节滑液的物理性状及细胞成分 ,对了解病理性关节滑液的变化规律 ,以及判断关节疾病的病性和早期诊疗有一定的临床实践意义。关于某些动物关节滑液性质的研究 ,国外有许多报道 ;国内只见有马的关节滑液中朊的电泳、健康蒙古马的关节滑液中细胞成分的研究和滑液计数法及其正常值等方面的研究。牛的有中国荷斯坦乳牛腕关节滑液某些成分的研究和以关节滑液的动态变化评价特定电磁波… 相似文献

滑膜炎是滑膜受到一定的刺激之后而产生的炎症现象,也被称为浆液性关节炎,在马属动物中比较多发,尤以骑乘马居多。病马经常出现关节腔滑膜充血和肿胀的现象,伴随关节的疼痛和敏感以及肿胀,还会对其运动功能产生不利的影响。本文主要是对马属动物跗关节滑膜炎的发病原因和临床症状进行分析,探讨其综合治疗方法。 相似文献

There is limited information on the treatment of lateral malleolus (LM) fractures in the horse, with no previously published case series for the outcome following arthroscopic removal of such fractures. This report reviews and evaluates findings of a retrospective study of 13 horses admitted to a private equine referral hospital over a 10 year period (1999–2009) that underwent arthroscopic removal of fractures of the LM. Hospital records were reviewed and details including patient history, aetiology of the fracture and limb affected, results of all diagnostic tests and surgical reports were documented. Performance information concerning Thoroughbred horses that went onto race post operatively was collected using an online database. Owners and trainers were contacted regarding the return to performance for non‐Thoroughbred cases or those that did not go onto race post operatively. Of the 13 horses presented, 12 were Thoroughbreds, 9 of which were National Hunt racehorses and 3 were Flat racehorses. The other horse in the study was used for general purpose riding. All cases presented with an acute unilateral fracture. Eleven of the 13 had >6 months post operative follow‐up and all were nonlame. Of the 12 Thoroughbreds, 10 have raced again, a total of 104 times (median 5 times). The median time from surgery to return to racing was 241 days (180–366 days). It is concluded that horses with fractures of the LM have an excellent prognosis for return to full athletic performance following arthroscopic debridement; and that arthroscopic fragment removal is an appropriate treatment method for fractures of the LM. 相似文献

Light and electron microscopic examination was made on equine synovial membrane from 23 healthy joints, nine joints with synovitis caused by intraarticular fracture and 10 joints with synovitis caused by osteochondrosis dissecans. Histologically as well as ultrastructurally the equine synovial membrane from healthy joints was of principally the same character as described in other species. Three types of synovial membrane — areolar, fibrous and adipose — and two types of lining cell were distinguished histologically. Ultrastructurally three types of lining cells were distinguished: A and Β type and an intermediate cell type. In healthy joints they were loosely arranged, parallel to the joint surface in an intercellular matrix, which was in direct continuity with the joint space. In joints with intraarticular fracture there was mild inflammation of the synovial membrane. There was elongation and hyperplasia of the lining cells with a relative increase in type A cells. The cell surface of lining cells was increased through filopodia. There was also an increase in cytoplasmic organelles i.e. hyperplasia of rough endoplasmic reticulum and Golgi complexes in Β type cells and an increase in lysosomes, and increased numbers of vesicles of varying types in A cells. In joints with osteochondrosis dissecans the lining cell hyperplasia and the inflammation in the synovial membrane were more prominent. Ultrastructurally the same alterations as in the previous group were seen including a relative increase in the number of A cells but degenerative changes were common in the lining cells. These changes were dilatation and vesiculation of rough endoplasmic reticulum, mitochondrial condensation, dilatation of the nuclear envelope and loss of plasma membranes, leading to disintegration of cells. 相似文献

OBJECTIVE: To evaluate the value of microarthroscopy in the equine midcarpal joint using the vital stains methylene blue, trypan blue, neutral red, and Janus green B to observe components of the synovial lamina propria, vascular architecture, and synoviocytes. STUDY DESIGN: Experimental. ANIMALS: Ten horses. METHODS: Microarthroscopy of left and right midcarpal joints was performed with and without vital staining of the synovium. Four vital stains (methylene blue, trypan blue, neutral red, and Janus green B) were evaluated, with each stain used in 5 joints. Synovial biopsy specimens were collected from the dorsomedial and dorsolateral aspects of the joint. RESULTS: All dyes were biocompatible. At x 60 without vital staining, synovial surface topography, vascular network, and translucency were observed. Intra-articular vital dyes improved evaluation of synovial surface topography. At x 150 with vital staining, individual synoviocytes were clearly identified with all dyes, except neutral red. Although methylene blue provided the best in vivo microscopic differentiation of the structure of the intima, trypan blue had superior retention in conventionally processed synovial biopsies. CONCLUSIONS: Methylene blue, trypan blue, neutral red, and Janus green B stains can be used safely for microarthroscopy. Good visualization of cells and vascular network can be obtained by microarthroscopy, and microarthroscopic evaluation of the synovium compares favorably with conventional histologic evaluation of biopsy specimens. CLINICAL RELEVANCE: Microarthroscopy may be beneficial in both research and clinical diagnosis of equine articular diseases. 相似文献

磷对奶牛红细胞膜脂质的影响 总被引:5,自引:0,他引:5
对15例临床上有明显低磷血症的奶牛血清磷、红细胞膜脂质成分进行了测定。结果表明,低磷血症奶牛血清磷、红细胞膜磷脂明显降低;红细胞膜胆固醇及膜胆固醇/磷脂摩尔比值(nch/npl)明显升高,与健康对照组牛相比差异极显著(P<0.01);直线相关分析表明,血清磷与红细胞膜磷脂之间呈极显著正相关(r=0.917,y=10.852x+3.196,P<0.01);与红细胞膜胆固醇以及nch/npl之间分别呈显著负相关(r=-0.940,y=2.850x-1.072,P<0.01;r=-0.920,y=1.968x-1.401,P<0.01)。此外,红细胞膜微粘度与膜磷脂之间呈显著负相关(r=-0.954,y=19.122x-4.384,P<0.01),而与膜胆固醇以及nch/npl之间呈显著正相关(r=0.988,y=0.927x+0.964,P<0.01;r=0.978,y=-0.293x+1.113,P<0.01)。结果表明,磷是红细胞膜脂质成分改变的先决因素,而后者又是红细胞膜流动性及膜结构、功能发生变化并导致膜损伤的一个重要因素。 相似文献
