RESUMO
Objective To discuss the influence of Yifei-Kangxin capsule on MMP-1 in Wistar rats model with pulmonary heart disease. Methods 40 Wistar rats with pulmonary heart disease were averagely grouped as Normal Group, Model Group, Therapeutic Group and Comparative Group randomly by weight. The rats in Therapeutic Group were given Yifei-Kangxin capsule and the rats in Comparative Group were given Nifedipine. The course of treatment was 15 days. The rats were killed at the next 7th, 14th and 28th day separately to test MMP-1 in pulmonary tissue. Results After the treatment, the expression of MMP-1 in pulmonary tissue of the Therapeutic Group[7 d, 14 d, 28 d was(0.231±0.017)ng/m、(0.308±0.081)ng/m、(0.358±0.074)ng/m]was lower than the Model Group[7 d, 14 d, 28 d was(0.266±0.036)ng/m 、(0.315± 0.060)ng/m、(0.612±0.091)ng/m]. Conclusion Yifei-Kangxin capsule can inhibit the expression of MMP-1 in the rats model pulmonary heart disease.
