Re 1 cm with the microscopic scale corresponded to 0.39 mm of actual thickness. The total score of all five parameters represented the severity of OA progression in every histological section. The sum of all scores from all histological sections of each animal represented the total score for that animal. The statistical evaluation was determined by the median along with the imply on the sums of the total scores of all the animals in every remedy group.Statistical analysisSpecimen collectionAfter the rabbits have been euthanized, treated knee joint specimens were collected by osteotomy three cm above andThe data are expressed as the mean ?the normal deviation on the different measurements. The statistical significance of intergroup variations was analyzed employing one-way evaluation of variance (ANOVA) and the Duncan post-hoc test. Differences with a P value less than 0.05 were considered statistically considerable.Lu et al.
