The effect of diosgenin on interleukin-6 in atherosclerosis rats / 国际中医中药杂志

ABSTRACT

Objective To investigate the effect of diosgenin tablet on interleukin-6 in the serum and artery of experimental atherosclerosis (AS) rats.Methods Sixty male SD rats were assigned randomly into five groupsgroup of sham operation (GSO,n =12),group of model (GM,n =12),group of Aspirin (GA,n =12),group of Diosgenin tablet in small dosage (GDS,n =12),and group of Diosgenin tablet in large dosage (GDL,n =12).After 7 days,the balloon-injured carotid artery angioplasty was performed except GSO.After 3 months,rats were killed.The rats' carotid arteries were stained with hematoxylin-eosin.Image analysis system was applied to measure the area of lumina and the thickness of wall to evaluate the ratio of W to L.Their blood IL-6 was detected.The expression of IL-6 in the aorta was measured with western blot.Results In the injured side,the W/L ratios of carotid artery in GDL and GDS(0.615±0.040、0.753±0.043)were much thinner than that of model group (0.803±0.043).That of GDL was thinner than GA (0.759±0.049).Compared with the model group (59.636±4.874)pg/ml,the level of serum IL-6 was decreased in GDL and GDS [ (42.582 ±4.724)pg/ml、(49.055 ±4.791) pg/rnl],GDL was much lower than GA[ (52.563 ±4.581) pg/ml].Western blot method showed that the levels of IL-6 in GDL and GDS (0.296±0.016、0.435±0.015)were significantly decreased compared with GM (0.455 ±0.026).GDL was significantly lower than GA (0.426±0.012).Conclusion Diosgenin can reduce the levels of serum and arteries IL-6 in the experiment atherosclerosis rats.
