Capillary neoformation in skeletal muscle of dipyridamole-treated rats

Rats were given 0.3 mg dipyridamole i.p. twice a day, 5 days/week for 3 weeks. Morphometric determinations of the hindlimb skeletal muscle of these animals showed that they had a higher degree of capillary vascular supply than the muscles of sham-injected control rats. The number of capillaries per muscle fiber was increased by 24%, the number of capillaries/mm2 by 22% and the number of capillaries in contact with each muscle fiber by 22%.
