[The vascularisation of the granulation tissue in different ages. - Its importance for wound healing (author's transl)].

The part of capillaries of a plastic sponge granuloma was determined in rats of different ages. It was found that granulation tissue of older rats contains significantly fewer capillaries than that of young animals. The diminished vascularisation of granulation tissue may be responsible for the deterioration of wound healing in aged individuals.
