Abstract
The objective of this study was to evaluate the effects of oral fish cartilage hydrolysate (FCH) on symptoms and joint tissue structure in rat developing osteoarthritis induced surgically. Osteoarthritis was induced in the right knee of mature male Lewis rats (n = 12/group) by surgical transection of the anterior cruciate ligament (ACLT) combined with partial medial meniscectomy (pMMx). Two weeks after surgery, rats were treated orally with either control (sterile H2O) or FCH for four weeks. Pain and function were assessed by dynamic weight-bearing test (incapacitance test), electronic Von Frey (EVF; hindpaw allodynia threshold), and pressure algometer (knee allodynia threshold). Time and groups differences at each time point were evaluated using a mixed model. The histological features were evaluated eight weeks after surgery using OARSI score. Mann–Whitney test nonparametric test was applied to compare OARSI score. ACTL/pMMx surgery significantly reduced weight-bearing and increased allodynia and sensitivity thresholds of the operated paw/knee. Globally, FCH improved these parameters faster, but no significant difference between control and FCH groups was observed. Eight weeks after surgery, rats developed moderate OA lesions. Compared with control, FCH did not significantly modify OA lesion severity assessed using the OARSI score. In this mechanically induced OA model, 4 weeks of supplementation with FCH had no significant effect on cartilage lesion, but tends to accelerate pain relief and joint function recovery. This positive trend may have opened the way for further investigation of FCH as potential treatment of joint discomfort associated with OA.

                    [description_short] => 
The advanced version of our Dynamic Weight Bearing Test for rodents (rats and mice) allows for faster paw identification, based on a video solution taking advantage of the most advanced algorithms of morphologic analysis, weight distribution and postural changes in dynamic conditions. An efficient and advanced alternative to traditional incapacitance tests (i.e. the paw pressure test or the force plate test) for assessing pain sensitivity in your research on analgesia, hyperalgesia and nociception involving rats and mice, including work on osteoarthritis, bone cancer, analgesic substances, Parkinson disease, allodynia...

As an electronic version of the classical Von Frey Filaments esthesiometer (or aesthesiometer), the latest evolution of Bioseb's Electronic Von Frey instrument for determining the mechanical sensitivity threshold in rodents (rats and mice) is a must-have instrument for your reseach on hyperalgesia and allodynia. By measuring and recording the force at which the animal exhibits a paw withdrawal reflex, pathologies related to sensory response and hyper- or hypo-aesthesia can be studied.

The EVF5 includes an embedded camera inside the stimulator handle and a new, dedicated software revolutionizing the experimental process.

Expand Your Analysis with Advanced Postural and Locomotor Calculations
BIOSEB’s renowned Dynamic Weight Bearing (DWB2) system is now more powerful than ever with the addition of the Postural Module. This optional software upgrade extends standard weight-bearing analysis by integrating unique calculations designed to quantify subtle aspects of postural balance, locomotor patterns, and compensatory behaviors.
Developed in collaboration with Dr. Tighilet’s lab from Aix Marseille Université-CNRS, the Postural Module improves your DWB2, providing valuable endpoints for studies on pain, neurology, vestibular dysfunction, and neurodegenerative disorders.
