The preventive effects of two nutraceuticals on experimentally induced acute synovitis.
- Journal Article
Summary
The research article explored the preventative impacts of two nutraceuticals on synovitis, a form of joint inflammation, in horses. Using an experimental model, it was found that the nutraceuticals seemed to exhibit anti-inflammatory effects.
Objective and Methodology
The study aimed to:
- Evaluate the preventive effects of newly derived nutraceuticals on induced synovitis, benchmarking them against positive and negative control treatments.
The researchers conducted a blind, randomized, controlled experiment using 24 healthy Standardbred horses. The horses were divided into four groups, three of which received different treatments (AT supplement, HP supplement or meloxicam) and one group received a placebo.
These treatments aimed to test their impacts on synovitis, an inflammation in the joints, which was triggered in the right intercarpal joint of each horse by an injection of Escherichia coli lipopolysaccharide (LPS). Throughout the study duration, several variables like blood and synovial fluid, and lameness were monitored at different time points.
Results of Study
The study found:
- Before the treatment and intra-articular challenge (injection of LPS to induce synovitis), there were no significant differences among groups with regard to any parameters under observation.
- Following the injection, horses that received the placebo showed higher total protein (TP), total nucleated cell count (TNCC), and prostaglandin E (PGE) in the synovial fluid compared to those who received meloxicam.
- Horses receiving nutraceuticals resulted in significantly lower TP, TNCC, and PGE in the synovial fluid as compared to placebo.
- No significant differences noticed in interleukin-6, glycosaminoglycans, type II collagen synthesis or matrix metalloproteinase among different treatment groups.
- All treatments could be administered without harmful effects.
Conclusion
In conclusion:
- The study demonstrated that although there was evident synovitis, the induced lameness was too mild to detect. Therefore, the researchers conclude there’s room for further investigations using a more substantial model that captures clinically significant outcomes, like lameness.
- The nutraceuticals under examination seemed to display anti-inflammatory effects on induced synovitis, laying the groundwork for future research to gauge their potential application clinically.
