Abstract:
AIMS:The aim of study is to investigate the effect of nifedipine on viral myocarditis in an animal model. MAIN METHODS:Four-week-old male DBA/2 mice were inoculated with 2 pfu of encephalomyocarditis virus (EMCV) and randomized to nifedipine (n=10) or control (n=10) group. The control group was fed by regular chow and the nifedipine group contained 0.01% of nifedipine. Mast cell density was counted, and expressions of messenger RNAs of stem cell factor (SCF), matrix metalloproteinases (MMPs), pro-collagen I, mast cell proteases, tumor necrosis factor-alpha (TNF-alpha), and interleukin-6 (IL-6) were evaluated by RT-PCR. KEY FINDINGS:The area of myocardial necrosis was smaller in the nifedipine vs the control group (mean+/-SD, 1.2+/-1.3% vs 3.8+/-1.8%, respectively, P<0.005). The mast cell density (count/mm(2)) was lower in the nifedipine vs the control group (mean+/-SD, 0.23+/-0.16 vs 1.08+/-0.45, respectively, P<0.0005). The expressions of MMPs, mast cell proteases, TNF-alpha, IL-6, SCF and pro-collagen I were lower in the nifedipine group than in the control group (P<0.05). SIGNIFICANCE:Nifedipine inhibited the activation of various participants in inflammatory and immune reactions in EMCV myocarditis.
