Joint diameters of each legs had been measured applying a digital caliper to evaluate swelling degree. Each absolute enhance in joint diameter as well as the ratio between treated and intact joints (in % from the intact joint) from the similar animal had been assessed. Joint diameter ratio was calculated according to the following equation:.
