Nighty rats were randomly divided into the groups of control, myocardial infarction and doxycycline, which were given orally 48 hours before and 48 hours after MI with 30mg/Kg per day. Protein and mRNA extraction was done on left ventricular samples containing scar and myocardium together. Samples were assayed from 1 day to 4 weeks post-Mi. The activity of MMPs was measured by zymography and collagen amount by the method of chloramine T, the ratio of II III collagen was assessed by immunohistochemical stain. Protein and mRNA of MMP-2, 9, TIMP-1 were determined by Western-Blot and RT-PCR.
