our approach serves several purposes : to demonstrate the response of aortic cell nuclei to a changing environment ( e.g . hypercholesterolemia , experimental diabetes , drug treatment ) , to apply the acridine orange ( ao ) ultracytochemical method , and to determine the euchromatin/heterochromatin ( eu/het ) ratio by morphometric procedures as suitable criteria , and to emphasize the differential nuclear activity of adventitial cells .
