Leaves of Ficus glumosa are used in northern Cameroon and southern Chad for the treatment of cardiovascular diseases, as food and as a stimulant for milk production in both women and animals. Atherosclerosis is a disease in which frequency increases with age. The first lesions appear at the young subject during adolescence. Atherosclerosis lesions appear very precociously and worsen with age. They interest the levels chronologically aortic, coronary then carotid. Age is a risk factor in that it reflects the exposure time of individual to the other risk factors. The frequency of the atherosclerosis increases with age because of the aging of the cells. This study was undertaken to evaluate the hypolipidemic and anti-atherosclerotic properties of aqueous extract of the leaves of F. glumosa in rats with hypercholesterolemia (HC). 60 male rats were fed for 4 weeks with a high-cholesterol diet (1%) and 3 doses (225, 300 and 375 mg/kg) of extract of F. glumosa were used in these experiments. The experiments were conducted under the same conditions with atorvastatin (1 mg/kg), as pharmacological reference substance. The effects of F. glumosa on weight gain, water and food consumption, levels of serum lipids and lipoprotein lipid oxidation and stress markers in the blood and liver were examined. The administration of F. glumosa extract prevented significant (P<0.05) elevation in TC, LDL-c, VLDL-c, hepatic and aortic TG and TC. The atherogenic, triglyceride, and lipid peroxidation (TBARS) indexes were also decreased in the rats treated with the extract. F. glumosa favored the performance of fecal cholesterol. It also significantly inhibited the changes and the formation of aortic atherosclerotic plaques. These results revealed the hypolipidemic and antiatherosclerotic effects of F. glumosa extract and support the traditional use of the extract of this plant in the treatment of hypertension and diabetes.
