A histochemical examination of autogenous microarterial graft to arteries

A comparative study on the localization of enzyme activities in the 3 individual layers of the femoral artery of albino rabbits and the grafted artery revealed. 1) Very active energy metabolism was observed histochemically even in the grafted vessels, tissues usually regarded merely as a duct. 2) On a long-term observation, the enzyme activity in the grafted vessels never returned to normal. 3) All enzyme activities decreased after 3 to 6 months follow the grafting.
