Study the effect of green tea extract on lipid profile in nitrate treated rabbits

Abstract

The present study was conducted to determine the effected of using an aqueous extract of green tea in lipid profile in rabbits treated with sodium nitrate. To achieve this goal, 28 local adult female rabbits, were randomly divided into four equal groups in different cages. The first group has been arranged as control group and has been drenched the distilled water daily for 60 days. While the second group (T1) has been drenched aqueous extract of green tea at a dose of 200 mg / kg of body weight for a period of 60 days, while the third group (T2) has been drenched the aqueous extract of green tea at a dose of 200 mg / kg of body weight and at the same time they have been dosed with sodium nitrate dissolved in distilled water at a dose of 300 mg / kg of body weight, while the fourth group (T3) have been drenched with sodium nitrate dissolved in distilled water at a dose of 300 mg / kg of body weight for a period of 60 days. The results of lipid profile test show significant increase in total cholesterol and low density lipoprotein in a (T3) group, as well as there was a significant decrease in a (T1) group, with no significant differences between (T2) and control group. While in the triacylglycerol and very low density lipoprotein show significant incense in the T3 group compared with the rest of the groups. In concern to the high density lipoprotein concentration significant decrease in (T3) group and significant increase in the (T1) group, while the concentration of (T2) was no significant increase close to the concentration of the control group.
