[Part of ascorbic acid in the maintenance of the blood capillary wall. New data (author's transl)].

The part of ascorbic acid in the blood capillary wall is shown by deficiency experiment. The pictures obtained by electron microscopy show that, non only is the ascorbic acid needed for the structure integrity of the basement membrane, but also for the permeability of the capillary wall, which when this compound is lacking becomes too important.
