The explanation has not been found yet, and it is not known whether it is the tissue expression to an inflammatory and repair phenomenon or if it represents a permanent damage of the joint tissue. Special attention should be paid to the methodology used in this study. Samples of subchondral bone and articular cartilage were analysed using different quantitative and qualitative microscopic methods and micro-CT. Histologic assessment of OA is currently considered as the gold-standard for determining the presence, extent and severity of the disease using Mankin [37] or modified Mankin scoring systems, [https://dx.doi.org/10.3389/fnhum.2013.00596 title= fnhum.2013.00596] but recently the histomorphometry using computer analysis systems [24] has been introduced in OA studies with a greater degree of objectivity and reproducibility compared to previous qualitative studies. Micro-CT has become in recent years the goldstandard for three-dimensional analysis of bone microstructure and its objectivity and reproducibility was comparable to histomorphometry. Although normally when the cartilage structure was quantified using micro-CT, the process involved complex staining techniques with radiopaque agents [38?0], in the present study the scan conditions have been adjusted to achieve a correct cartilage visualisation without contrast agents and it was enough to be able to quantify its morphology.

Animal models have been widely used to study the efficacy of therapies in order to improve, fight or prevent OA. Surgically-induced OA models, resulting in joint instability, produce a gradual progression of the joint degeneration and mimic the pathogenesis and pathology of the human traumatic OA [30, 31]. Since the first model carried out by Paatsama (1952) [32], many studies havesurgically induced OA using meniscectomy and/or transection of the collateral and cruciate ligaments in different animal species [33]. Partial medial meniscectomy in rabbits results in mild to moderate changes in the joint, resembling those in humans, thus it has been extensively used for testing potential chondroprotective agents [34]. Our animal model was a combination of meniscectomy and ligament transection to avoid the great capacity of rabbits to heal the transected meniscus with fibrous tissue and, similarly to the results obtained by other authors, the results in the present study have shown that this model produced degenerative changes with respect to the healthy contralateral joint [30].

The histologic evaluation of the synovial membrane in the OA group revealed moderate to severe inflammatory changes with thickening of the lining cell layer, hyperplasia and infiltration with inflammatory cells. In the diacerein-treated group (OA + DC) these changes are milder than in the OA group, although, as in a canine cruciate-deficiency model [12] the results are not statistically significant, as the animals of this OA + DC group obtained values halfway between healthy and osteoarthritic ones. The same results were observed inthe cartilage, where a reduction of the thickness is observed in treated animals with respect to the OA group. In the paraffin-embedded samples there were no differences between groups (although the cartilage pathology is almost significant). A possible explanation could be the substantial variability due to the use of a qualitative subjective scoring system for their evaluation; another explanation (comparing these results with the calcified samples) could be that due to decalcification the integrity of the samples (chiefly bone and calcified cartilage) [https://dx.doi.org/10.1002/per.1944 title= per.1944] may have been altered [24].Non-calcified cartilage. Previous studies revealed the beneficial effect of this drug not only for cartilage protection, but also for synovitis and reduction in bone erosion in a mice model of inflammatory arthritis [41]. The mechanisms of the antiinflammatory effect of diacerein have not yet been completely clarified but Tamura et al. (2002) [42] demonstrated, using inflammatory animal models, a different spectrum of anti-inflammatory activity of diacerein than those of NSAIDs, which may be due to the inhibition of IL-1 and the production of reactive oxygen species [42, 43].

However, in decalcified samples, the results for the OA + DC group were closer to normality than those obtained for the OA group. In the samples [http://femaclaims.org/members/cork25jury/activity/1186604/ E-conditioning) for paired and CS-alone trials Transform within the curve of] evaluated by a histomorphometric quantitative methodology, results showed improvement in the diacerein-treated group compared to the one treated with placebo, although differences were not significant. In cartilage parameters there were statistical differences in Cg.Th and nCg.Th between the OA group and the CTRL + DC group and for the latter also with the CTRL group. There were no differences between OA and OA + DC, but nor between OA + DC and CTRL + DC and the tendency of values was to approximate joint values to normal.

The results obtained from the undecalcified samples were better than those from the decalcified ones because of a better conservation of the tissue structure and because the computer evaluation has a greater degree of objectivity, accuracy and reproducibility, as well as the micro-CT [24], with comparable results between both. In our study, the subchondral bone showed no statistical differences, so further studies may be needed in this regard.
