①目的探讨贻贝多活素对小鼠心肌营养性血流量影响。②方法根据８６Ｒｂ对心肌亲和力强的特点，采用同位素标记方法研究贻贝多活素２，４ｇ／ｋｇ体重对小鼠心肌营养性血流量影响。③结果贻贝多活素２，４ｇ／ｋｇ体重均较对照组显著增加小鼠心肌营养性血流量（ｔ＝２．８３，Ｐ＜０．０５；ｔ＝２．９６，Ｐ＜０．０１）。④结论贻贝多活素能改善心肌氧和营养性物质的供应。
Objective To investigate the effect of mussel activin on cardiac nutritional blood flow in mice. Methods According to the characteristic of strong myocardial affinity of 86Rb, isotope labeling method was used to study the effect of 2,4-glucosidase activity of mussel on cardiac nourishing blood flow in mice. (3) Results Muscardin 2,4,4 kg / kg body weight significantly increased myocardial trophic blood flow in mice (t = 2.83, P <0.05; t = 2.96, P <0.01) . ④ Conclusion Multi-activin mussel can improve myocardial oxygen and nutrient supply.
