Experimental data showed that ERP (120-480 mg/kg) dose dependently attenuated the capillary permeability accentuation induced by acetic acid in mice.
Other research could focus on the use of agents to reduce pulmonary capillary permeability and provide membrane stabilization, such as corticosteroids, oxygen free-radical scavengers, and cyclo-oxygenase inhibitors.
(In medical jargon this is known as an increase in capillary permeability.) Because of these dual actions, bleeding in an RU486 abortion usually remains profuse for days.
It combats capillary permeability and fragility; it inhibits the clumping of blood; it lowers fat and cholesterol levels; it improves circulation and reduces cardiovascular abnormalities.

The tight junction (TJ) between cells is important for maintaining capillary permeability. The intercellular gap is increased when the TJ is damaged by various causes, which may lead to the increase in vascular permeability (6).
Venoactive drugs decrease venous tone, thereby reducing capillary permeability and the tendency to oedema.
Pulmonary edema is another critical issue of acute lung injury, which results from breathing membrane barrier (BBB) dysfunction, and capillary permeability increase [18, 19].
It has been suggested that Pycnogenol may bind to the blood vessel wall proteins and mucopolysaccharides and produce a capillary 'sealing' effect, leading to a reduced capillary permeability and oedema formation.
