Opis:
Introduction and aim. Osteoarthritis (OA) is generally a progressive disease that affects synovial joints, resulting in abnormalities to articular cartilage subchondral bone, synovium, and adjacent soft tissues. The purpose of this work was to investigate the specific activity of chondroitin sulfate (CS) in intra-articular and intramuscular administration to laboratory rabbits in experimental OA. Material and methods. OA was induced in rabbits by a single injection of mono-iodoacetate in knee joint. CS was administered intra-articularly and intramuscularly. The analysis of biochemical markers and macroscopic assessment of rabbit knee joints was performed. Results. Intramuscular and intra-articular injection of CS reduces the intensity of the degenerative-dystrophic process due to the impact on inflammatory and the activation of anabolic mechanisms. Intra-articular administration of CS leads to a greater increase in the level of factors of bone and cartilage formation and a greater decrease in the levels of factors of the acute phase of inflammation and factors that destroy the cartilage matrix. Conclusion. Intramuscular administration of CS revealed a lower intensity of destructive changes in the cartilaginous surface of the knee joint, and intramuscular – the absence of cartilage destruction and defects of the cartilaginous surface, which indicates the peculiarity of the topical effect of the CS.

Introduction. Osteoarthritis (OA) is generally a progressive disease that affects synovial joints, resulting in abnormalities to articular cartilage subchondral bone, synovium, and adjacent soft tissues. Aim. The purpose of this work was to examine the histological changes in knee cartilage and bone following the administration of two different chondroitin sulfate products in two experimental OA models in rats. Material and methods. OA was induced in rats by either a single injection of mono-iodoacetate or four once-weekly injections of dexamethasone. 70 adult rats were included: 30 received mono-iodoacetate, 30 received dexamethasone and the 10 remaining controls received no injection. Samples of knee bone and cartilage were then analyzed histologically. Results. Animals with OA that received CS had significantly less inflammation, improved motor activity, and better analgesia compared with those that did not receive CS, with little difference between products. Histologically, both products reduced the signs of OA and resulted in the activation of regenerative processes of cartilage and bone and stimulation of proliferation and formation of amorphous material. Conclusion. These results substantiate the importance of using high-quality pharmaceutical-grade CS to ensure optimal efficacy and safety of the final product in patients with OA

Opis:
Collagen type I and glycosaminoglycans (GAGs) were immobilized on the surfaces of two types of porous biodegradable poly(L-lactide-co-glycolide) (PLGA) scaffolds with pore size in the range of 250-320 µm and 400-600 µm. Two methods of coating were evaluated differing in the way of how the fibrillogenesis solution was introduced into the pores. The distribution of the immunostained collagen in the volume of the scaffolds was analysed with a laser confocal microscope (LSM). The total amount of collagen and GAGs was measured by Sirius Red and Toluidine Blue assays, respectively. The potential of the scaffolds for cell colonization and differentiation was tested in a dynamic cell culture system using human osteosarcoma cells (SAOS-2). The proliferation of SAOS-2 cells was measured by determining the DNA content on days 2 and 7, while differentiation was analyzed by Calcium- and Phosphate-Assays on days 7 and 14. Differentiation of cells was improved by increasing the pore diameter of the scaffolds, and artificial extracellular matrix (aECM) coatings had an additional positive effect for the scaffolds of both pore sizes.
