This research was designed to study the obesity which induced by rats fed on high fat diet which characterized by gain in body weight and elevation of some immunological parameters which often concomitant with mild to moderate fatty streak in coronary artery and the effects of atorvastatin treatment of male albino rats, the result showed:
High significant increase(p<0.0005)in total and gain body weight of positive control rats, while atorvastatin treatment caused significant decrease(p<0.005) in both total and gain body weight of hyperlipidemic rats as compared with positive control group, also atorvastatin reduce gain body weight in normolipidemic rats as compared with negative control group.
There were high significant increase(p<0.0005)in C3,C4 in normolipidemic rats which treated with atorvastatin, while there were significant increase(p<0.0005)in CRP,C3,C4 in hyperlipidemic rats of positive control group, whereas the treatment by atorvastatin result in returned the concentration of CRP,C3,C4 to its normal values as compared to negative control rats.
The histological sections of coronary arteries and its some branches were revealed the presence of fatty streak, infiltration of fat laden cells(foam cells)in subintimal layer of coronary arteries of positive control rats ted on HFD,also smooth muscle cell proliferation, vacuolar of tunica media were observed in the coronary arteries of these animals as a signs of onset of atherosclerosis, whereas atorvastatin reduced completely the presence of all these changes after three months of treatment.Thus our conclusions that atorvastatin reduced the body weight gain in hyperlipidemic animals, induce inflammatory changes in normolipidemic animals and reduced all signs of atherosclerosis in coronary arteries.
