Abstract:
Histochemically, tunica intima and the elastic fibres of tunica media and tunica adventitia of coronary arteries showed PAS positive reaction and the internal elastic lamina was highly PAS positive. The tunica intima and tunica adventitia showed moderate reaction, while the tunica media showed weak reaction for acid mucopolysaccharides in the coronary arteries. In aorta, the tunica intima including the internal elastic membrane was PAS positive. In the tunica media and tunica adventitia all the elastic fibres showed PAS positive reaction. In aorta weak reaction for acid mucopolysaccharides was observed in the tunica intima with moderate reaction in tunica media and tunica adventitia. Fat droplets were observed in the tunica adventitia and the surrounding connective tissue of coronary arteries and aorta of Group-II and Group-III animals.
