| Abstract: | Ultrastructural changes of synovial capillary and venule wall have been investigated in rabbits with antigen-induced arthritis, with the permeability of microcirculatory bed determined using 99mTc pertechnetate. The correlation between the incidence of ultrastructural microvascular damages in exudative phase of arthritis and the increased permeability has been established. Ultrastructural changes occurring in proliferative phase of arthritis are considered as adaptive to conditions of increased permeability. |
