Canine total knee replacement performed due to osteoarthritis subsequent to distal femur fracture osteosynthesis. Two-year objective outcome     

Eskelinen EV  Liska WD  Hyyti?inen HK  Hielm-Bj?rkman A 《Veterinary and comparative orthopaedics and traumatology》2012,25(5):427-432

A 27-kg German Shorthaired Pointer was referred for evaluation due to the complaint of left pelvic limb lameness and signs of pain in the left stifle joint. Radiographs revealed signs of a healed supracondylar femoral fracture that had been previously repaired at another hospital with an intramedullary pin and two cross pins. In addition, there were signs of severe osteoarthritis (OA). The OA had been managed medically with administration of carprofen and nutraceuticals for nine months without any improvement. Left total knee replacement (TKR) surgery was performed to alleviate signs of pain. The patient was assessed preoperatively and at six months, one year, and two years after surgery using radiology, force platform analysis of gait, thigh circumference measures, goniometry, and lameness evaluation. Following surgery, the dog resumed normal activity without any signs of pain and a good quality of life at 3.5 months. Force plate analysis found that peak vertical force on the TKR limb was 85.7% of the normal contralateral limb after two years. Total knee replacement was a successful treatment to manage knee OA associated with a healed distal femoral fracture and internal fixation in this dog.  相似文献   

Primary synovial osteochondromatosis of the stifle in an English Mastiff     

Smith TJ  Baltzer WI  L?hr C  Stieger-Vanegas SM 《Veterinary and comparative orthopaedics and traumatology》2012,25(2):160-166

A two-year-old, 97 kg, male neutered English Mastiff was evaluated for left pelvic limb lameness of five months duration localized to the stifle joint. Following radiographic, computed tomographic and arthroscopic examination, the lameness was subsequently diagnosed as being caused by primary synovial osteochondromatosis. In total, 194 osteochondral bodies were removed using arthroscopy in combination with a mini-arthrotomy. Histology and immunohistochemistry of the loose osteochondral fragments confirmed the diagnosis with a moderately high degree of differentiation and low cellularity. Nuclear staining for Ki-67 revealed decreasing differentiation and increasing cellularity in the fragments. At the 13 months telephone follow-up the owner reported that the dog was free from lameness and had a vastly improved function compared with preoperative levels, although mild lameness did occasionally occur. This is the first report of computed tomography, arthroscopy and immunohistochemistry confirming a case of primary synovial osteochondromatosis in a dog.  相似文献   

香梨越冬期树干形成层保护酶活性变化特性分析     

郑晓辉  巴特尔?巴克  海利力?库尔班  茹鲜?木沙  刘珊珊 《东北农业大学学报》2012,(7):104-108

以库尔勒香梨树干形成层为主要研究对象,测定越冬期间香梨树干形成层、树枝及花芽组织保护酶活性变化特性,对比分析日灼组织保护性酶活性的影响.结果表明,在越冬期间形成层过氧化物酶(POD)、超氧化物歧化酶(SOD)、过氧化氢酶(CAT)的活性随着温度的降低而升高;阳面、阴面、树枝和芽的SOD活性差异不显著,但POD、CAT活性具有显著差异;日灼通过影响树干形成层温度导致树干形成层南北侧保护酶活性的差异,阳面酶活性较高  相似文献   

Analysis to On-off Voltage Wave and Its Parameter of Switched Power     

ZHONG Yuan? chang 《保鲜与加工》2003,(2):22-24

To analyse the working parameter of switched power, this article introduces the circuit model of switched power and the shaping process of its on off voltage wave. Aiming at analyzing to the voltage wave and parameter, an "assistant compensation" method is put forward. Based on this method, the voltage wave and parameter of switched power are theoretically analyzed and imitated. The imitation results indicate that the method is afeasible and advance one.  相似文献

Estimation Methods for DOA Based on Smart Antenna     

ZHANG Yi  WANG Ji? feng  LUO Yuan 《保鲜与加工》2003,(2):36-38

Smart antenna is one of the key technique in the third generation mobile telecommunication system. Main estimation methods for DOA(direction of arrival),i.e. ESPRIT, MUSIC, WSF, Mininorm,etc., are researched,the performances for DOA estimation based on smart antenna are analyzed by the research of theory, simulation experiment and the contrast algorithms between and Cramer Rao Bound.The research results aren't only propitious to research and develop for smart antenna,but also for the application of smart antenna in mobile telecommunication.  相似文献   

Fracture Occurrence Mechanism and Control Measure Research of Generator and Compressor Bracket     

XIONG Wei  DENG Zhao? xiang  CHU Zhi? gang  LIU Jian 《保鲜与加工》2003,(2):107-109131

During a minibus's practical road driving and engine test rig test for vehicle and engine reliability, the phenomenon of generator compressor bracket fracture appears and leads the generator compressor crankshaft belt rupture. It seriously affects the vehicle's operation performance. The article carries through engine test rig test and analysis, using frequency and spectrum technology to identify the bad vibration source combining FEA. It also researches vibration's occurrence, formation, propaganda and fracture mechanism. Based on this, the authors put forward countermeasure, which improves the dynamic characteristic of the system, decreases the vibration intensity and avoides the fracture of bracket and belt.  相似文献
