IL6 and cardiac hypertrophy: Results showed a significant decrease in cardiac hypertrophy (HW/BW = 0.0030 ± 0.0002 mg/g), echocardiographic parameters (LVEF = 54.12 ± 1.628% and LVFS = 20.40 ± 0.541%), hemodynamic parameters (HR = 411.0 ± 9.684 bpm, SBP/DBP = 84 ± 4.998/60 ± 3.062 mmHg) and downregulation of the expression of IL-4, IL-13, IL- 1β, IL-6 and TLR4 in the l-arg diabetic group compared to diabetic rats.
