The objective of this study was to determine whether a prophylactic regimen of intramuscular polysulfated glycosaminoglycans (PSGAG), administered to growing Thoroughbred foals, would significantly reduce the incidence or severity of osteochondritis dissecans (OCD) or traumatic joint lesions that had been found in untreated foals (historical controls) from the same farm during the preceding 3 years. The number of PSGAG-treated foals with clinically significant joint lesions was 44.1% lower than the number of foals with OCD/joint injuries that had been found in the untreated historical controls. Surgical intervention of the treated foals declined 87.7% from the incidence on the farm during the preceding 3 years. Although the incidence of OCD lesions of the hock, stifle, and fetlocks in treated foals was not significantly different from that found in the matched controls, the lesions in the PSGAG-treated foals resolved without surgery. These results suggest that PSGAG has the potential to improve the clinical course of osteochondrosis (OC) and OCD. Additional studies are underway to determine whether a shorter or more targeted prophylactic regimen will provide a similar benefit. 相似文献

Degenerative joint disease (DJD) or osteoarthritis in the equine is largely a result of biomechanical stressors that result in inflammation within the joint, which with continual exposure, leads to progressive degeneration. A myriad of therapies are available for treatment of horses with DJD including nonsteroidal anti-inflammatory drugs, corticosteroids, physiological modifiers, and biological therapies. C-phycocyanin, a protein-bound pigment found in blue-green algae, has been shown to have anti-inflammatory and antioxidant properties and is available as a diet supplement in people, dogs, and horses. Forty-one horses with naturally occurring lameness as a result of DJD were selected for this study. In a blinded study, horses were randomly assigned to either the commercial or placebo product that was fed once daily for 12 months. At selected time points, lameness evaluation was performed through objective gait analysis. Previous medical records for management of lameness were reviewed for all enrolled horses. No statistically significant differences existed within or between the two groups when gait was evaluated objectively nor within individual horses between time points. Review of medical records found that five treated horses had a decreased in frequency of intra-articular injection of corticosteroids. Although this study did not find statistically significant improvement of lameness with oral daily supplementation of C-phycocyanin in equine athletes, there appeared to be a trend of improvement in lameness during the loading period and a decrease in frequency of administration of intra-articular corticosteroids. Further investigations using a higher dose seem warranted. 相似文献

Detection of Clinically Relevant Pain Relief in Cats with Degenerative Joint Disease Associated Pain

Background
Detection of clinically relevant pain relief in cats with degenerative joint disease (DJD) is complicated by a lack of validated outcome measures and a placebo effect.Hypothesis/Objectives
To evaluate a novel approach for detection of pain relief in cats with DJD.Animals
Fifty‐eight client‐owned cats.Methods
Prospective, double‐masked, placebo‐controlled, stratified, randomized, clinical study. Enrolled cats were 6–21 years of age, with owner‐observed mobility impairment, evidence of pain in at least 2 joints during orthopedic examination, and overlapping radiographic evidence of DJD, and underwent a 2‐week baseline period, 3‐week treatment period with placebo or meloxicam, and 3‐week masked washout period. Outcome measures were evaluated at days 0, 15, 36, and 57.Results
Both groups significantly improved after the treatment period (day 36) on client‐specific outcome measures (CSOM) and feline musculoskeletal pain index (FMPI) (P < .0001 for both); there was no difference between the groups on CSOM or FMPI score improvement. After the masked washout period, more cats that received meloxicam during the treatment period had a clinically relevant decrease in CSOM score (P = .048) and FMPI score (P = .021) than cats that received placebo.Conclusions and Clinical Importance
Using both a client‐specific and a general clinical metrology instrument, owners of cats with DJD were able to detect evident recurrence of clinical signs after withdrawal of active medication than after withdrawal of placebo, and that this study design might be a novel and useful way to circumvent the placebo effect and detect the efficacy of pain‐relieving medications. 相似文献10.
目的:观察高频电火花水针疗法对家兔骨关节炎滑膜组织超氧化物歧化酶(SOD)和丙二醛(MDA)的影响,探讨其治疗膝骨关节炎(osteoarthritis,OA)的机制。方法:应用关节制动的方法复制OA模型,18只造模成功的中国家兔,随机分为高频电火花水针组(A组)、水针组(B组)和手法组(C组),A组用高频电火花水针加手法治疗,B组水针加手法治疗,C组仅予以手法治疗。1次/3d,疗程为1月。检测滑膜组织中SOD和MDA的含量。结果:A、B组滑膜组织中SOD、MDA水平与C组相比差异均有显著性(P<0.05),但A、B2组间差异无显著性(P>0.05)。结论:高频电火花水针疗法和水针疗法能提高OA滑膜组织中SOD活力,减少MDA含量,通过抗氧自由基代谢治疗膝骨性关节炎。 相似文献
