Morphometric analysis of the angioarchitecture of the synovial membrane in rheumatoid arthritis and osteoarthritis.
Using three different immunohistochemical methods we measured the number of vessels, vessel area and diameter and their form factor in the synovial membrane of 102 patients suffering from different joint disease. The variables were evaluated by means of immunomorphometric analysis. We found UEA (Ulex europeus) immunostaining to be the optimal method for quantification of data characterizing the vasculature of the synovial membrane. Irrespective of causes of the given joint disease, we found increases in the number of vessels, vessel perimeter, vessel area and the product of the number of vessels and vessel area over and against the control group (patients without arthritis). Consequences are discussed regarding local bioavailability of medicaments in the synovial membrane.
