Comparative Histochemical Studies on the Angioarchitecture of Coronary and Femoral Artery in Goat (Capra hircus)

Abstract

The present study was conducted on the coronary and femoral artery of 18 goats divided into three age groups viz. kid (up to 1 year), young (1-2 years) and adult (2 years and above) for recording the histochemical peculiarities at their origin, middle and termination points. The deposition of glycogen was limited to the tunica intima and adventitia of coronary and femoral artery with intense PAS activity was observed in kids and young in coronary artery whereas in kids and adults in the femoral artery, respectively. The deposition of lipids was found in all the tunics of the arteries, which showed an increased trend with the advancement of age in the animals. The deposition of calcium salts was only found in the tunica adventitia of proximal end of left femoral artery in adult animals. The acid and alkaline phosphatase activities were limited to the intima, adventitia and perivascular connective tissues of the coronary and femoral artery whereas intense activities were found in the femoral artery of kids.
