Abstract:
To investigate the anti-atherosclerotic effects of dietary hesperidin and naringin on ather-osclerosis in rabbits.Twenty-four adult healthy male New Zealand Large White rabbits were ran-domly assigned to four groups based on one factor:control(Con),model(Mod),hesperidin(HP),and naringenin(NG),each containing six rabbits and housed in solitary cages.During the experi-mental period,the control group received normal feed;the model group was fed high-fat for 30 d to establish the atherosclerosis,(AS)model and continued to be fed high-fat feed;the hesperidin and naringenin groups were fed high-fat for 30 d and then underwent AS modeling,and at a later stage,150 mg of hesperidin(or naringenin)was added to the diets at a rate of 1.5 mg per kg of di-et,respectively,for 30 d.Relative body quality,blood lipids,oxidation,and inflammatory factor lev-els were all assessed.At the end of the test period,the test rabbits were sacrificed to obtain the common carotid artery for histopathological section HE staining,Oil red O staining,and Sirius red staining in order to observe vascular tissue structure,lipid and inflammatory cell infiltration,and e-lastic plate and elastic fiber damage.The results indicated that the relative body quality of the mod-el,HP and NG groups increased rapidly,and the difference with the control group within the same period was highly significant(P＜0.01);The HP and NG interventions significantly decreased to-tal cholesterol(TC)and low-density lipoprotein cholesterol(LDL-C)levels(P＜0.01),while also leading to a significant increase in high-density lipoprotein cholesterol(HDL-C)levels(P＜0.01);MDA levels exhibited a significant decrease(P＜0.01),while SOD levels showed a notable in-crease(P＜0.01)following the HP and NG interventions;After HP and NG interventions,TNF-α and IL-1 were regressed(P＜0.01)and IL-10 was significantly elevated(P＜0.01);Compared with the control group,the model group showed approximately 41.8 and 2.5 fold thickening of the maximal endo-medial membrane,respectively,and the HP and NG interventions showed approxi-mately 13 and 15 fold thickening of the maximal endo-medial membrane,and both of the maximal medial membranes thickened by approximately 1.4 fold;Staining of pathological sections showed that HP and NG intervened to significantly reduce inflammatory cell infiltration,deposition of lipid components,slight thickening of the endothelium,and intact fibroblastic components.The results showed that the addition of HP and NG to diets could regulate blood lipids and exert anti-inflam-matory and antioxidant effects by inhibiting the expression of inflammatory factors and oxidizing factors,showing significant anti-AS effects,and the two effects were comparable.
