Evaluation of Locally Induced Osteoarthritis by the Complete and Incomplete Freund's Adjuvant in Mice. The Application of DEXA Measurements
The inflammatory reactions elicited in mice by subcutaneous injections of IFA and CFA had opposite effects when tested on local metacarpal shank bones and the distal epiphysis of shank bones. Although the intensity of the immune reactions was similar, IFA induced bone loss, while CFA induced bone formation, which was mostly periosteal in nature. BMC and BMD measurements were assessed by means of high resolution DEXA, using a hologic 4500A bone scanner with software dedicated for the analysis of small animal bones. DEXA scans were evaluated and related to histological and bone ash content analyses. The morphological and quantitative ash weight analyses of bones exposed to the adjuvants were consistent with DEXA bone density scan measurements.
