Abstract : Hypercholesterolemia is usually known as the presence of high levels of cholesterol in the blood, it closely related with the hazard of coronary heart disease and a possible indicator for early development of atherosclerosis. Octacosanol is one of policasanol components , policasanol is a mixture of higher aliphatic alcohols produces from isolation and purification of sugar cane wax (Saccharum officinarum)is one of the cholesterol-lowering drugs. Statins are the inhibitors of hydroxymethyl glutaryl coenzyme A (HMG CoA) reductase. They are mostly used to treat hyperlipidaemia. Thirty sixhealthy adult female rats. Weights and age of animals were (200-250 gm) and (10-12) weeks respectively they are Inducted to be hypercholesterolemicof 200 mg/dl .octacosanol extracted from Sugar cane plant (Saccharum officinarum)and determined by using gas chromatography – mass spectrometry (GC/MS).Animals were divided into 6 groups ( 6 rats per group) : all animals were treated orally for 8 weeks as the following: The first group (Control): animals were given Dimethyl Sulphoxide (DMSO) orally only 0.2 ml/ animal per day. The second group were only hypercholesteroled and given 0.2 ml/ animal per day of Dimethyl Sulphoxide (DMSO). The third group were hypercholesteroled and given Atorvastatin at dose (0.02 mg/ animal per day. The fourth group were not hypercholesteroled and given only Atorvastatin at dose (0.02 mg/ animal per day). The fifth group were hypercholesteroled and given Standard octacosanol at dose (0.02 mg/ animal per day). The sixth group animals were hypercholesteroled and given Extracted octacosanol at dose (0.02 mg/ animal per day). Serum levels of aldosterone , cortisol, T3 and T4 were determined by radio immunoassay. Results showed significant decrease of aldosterone and cortisol in hyperlipidemic group than control group , Also aldosterone levels in hyperlipidemic group that treated with atorvastatin were significantly decreased than those of control group. Results of T3 and T4 in groups treated with octacosanol –both the extracted and standard - were significantly decrease than those in animals of control group, while in groups treated with atorvastatin the levels of these hormones were modulated than those in control group.In conclusion both octacosanol and atorvastatine modulate aldosterone, cortisol, T3 and T4 hormones in female rats.
