Effect of Soybean Consumption on Histometry and Histochemistry of Tibial Plateau Cartilage in Female NMRI Mice after Osteoarthritis Induction

Osteoarthritis is the most frequent knee joint disorder among old generation where it causes serious motion limitation. The objective of present study is investigating the effects of a diet containing soybean meal ingestion on relative treatment effect on knee articular cartilage in osteoarthritis induced mice.
Material & Fifty immature female NMRI mice were accidentally divided into five groups. Control group received tap water and normal diet for three months. Sham group, as induced osteoarthritis model, received Ciprofloxacin by stomach Gavage method over two weeks, 20 Mg/kg of their body weight daily. First experimental group were osteoarthritis induced over two weeks and then received null soybean meal diet by three months. The second experimental group, were fed with designed diet based on %15 soybean meal during these three months. The third experimental group was ingested with the designed diet after osteoarthritis induction. After the experimental period, values of cartilage thickness at the middle part of tibial plateau, concentration of the extracellular matrix, and concentration of alkaline phosphatase in blood serum were determined among the groups.
Findings: Comparison between the groups showed that among the groups which were fed with the diet based on %15 soybean meal either with or without osteoarthritis induction, not only the cartilage thickness at the middle part of tibial plateau but also the concentration of the glycoproteins in extracellular matrix was significantly higher than those of the groups which received the normal diet (pDiscussion & Regarding the positive effects of the designed diet based on soybean meal on cartilage, addition of soybean meal in regimen in order to decrease the incidence of articular disorders can be recommended.
