Abstract:
Established rat models with subclinical hypothyroidism (SCH) were divided into three groups:subclinical hypothyroid(SCH),SCH treated with levothyroxine (L-T4),and control group.The L-T4 group displayed lowered total cholesterol and endothelin levels compared with the SCH group[(1.29 ±0.05 vs 2.38 ±0.55) mmol/L,(98.54 ± 32.43 vs 160.62 ±37.25) nmol/L,both P<0.05].Nitric oxide levels,left ventricular systolic pressure,and blood flow in abdominal aorta were significantly higher in the L-T4 group than those in the SCH group.The results of this study indicate that L-T4 treatment may improve endothclial dysfunction and hemodynamic changes in rats with SCH.
