Effect of Dan Hong injection on PON1, SOD activity and MDA levels in elderly patients with coronary heart disease.

OBJECTIVE To research the effect of Dan Hong injection (DHI) on PON1, SOD activity and MDA levels in elderly patients with coronary heart disease (CHD). METHODS 98 elderly patients with CHD diagnosed by coronary angiography were randomly divided into conventional treatment group and DHI treatment group, measured and analysis the serum PON1 activity, SOD and MDA levels before and after treatment in the two groups. RESULTS PON1 and SOD activity in elderly CHD patients were significantly lower than elderly non-coronary heart disease group, there was a significant difference between the two groups (P < 0.01); and MDA level in elderly CHD patients was significantly higher than elderly non-coronary heart disease group, there was a significant difference between the two groups (P < 0.01). There was a major change in PON1 activity, SOD and MDA after 4 weeks DHI treatment (P < 0.05). There was different degrees of change in PON activity, SOD and MDA after 4 weeks conventional treatment when compared with pre-administer DHI, but did not reach significant difference (P > 0.05); PON1 activity, SOD and MDA had significant different after 4 weeks treatment in DHI group compared with the conventional treatment group (P < 0.05). CONCLUSIONS There is lipid peroxidation in the elderly patients with the coronary heart disease. DHI can raise serum PON1, SOD activity and lower MDA to improve the antioxidant effect in elderly patients with coronary heart disease.
