Abstract:
Objective To observe the effects of modifiedDanshen Decoction on spermidine/spermine acetyltransferase (SSAT) /polyamine pathways of SD rats with IRI; To investigate its protective mechanism. Methods The model of IRI was established by ligating left anterior descending coronary artery for 30 min followed by reperfusion for 90 min. The SD rats were randomly divided into the control group, sham-operation group, model group and modifiedDanshen Decoction group, with 10 rats in each group. The myocardial infarction size was measured by using TTC staining. The contents of SSAT were measured by ELISA. The SSAT mRNA and SSAT protein expression level were detected with real-time fluorescent quantitative PCR method and Western blot, respectively. The contents of polyamines (putrescine, spermidine, spermine) in cardiac tissue were detected by HPLC. Results Compared with sham-operation group, the myocardial infarction size, the SSAT content, the SSAT mRNA and SSAT protein expression levels of model group increased significantly, the contents of polyamines decreased significantly, with statistical significance (P<0.01); Compared with model group, the myocardial infarction size of modifiedDanshen Decoction group was significantly reduced, while the SSAT content and SSAT mRNA and protein expression level decreased significantly, the contents of polyamines increased, with statistical significance (P<0.05, P<0.01).ConclusionModifiedDanshen Decoction can adjust the SSAT polyamine pathways and increase polyamine content in cardiomyocytes, and thus play a role of protection of myocardial ischemia-reperfusion injury.
