Objective:To observe the protection of genistein(Gen)on rat’s myocardial hypertrophy caused by isopropylarterenol(iso)
the changes in Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities
and the content of hydroxyproline(Hyp).Method: The rat’s myocardial hypertrophy model was formed through hypodermic injection which extended 10 days at back skin with iso
1 mg·kg-1·d-1.Once the model was formed
various doses of Gen
DMSO or NS were administrated through hypodermic injection from the second day
and the process will extend 14 days.After the last administration
the rats were fasted for 12 hours
and then hearts were taken under anesthesia.The indexes of heart and left ventricle were calculated
the concentration of Hyp as well as the activities of Na+-K+-ATPase and Ca2+-Mg2+-ATPase in myocardial tissue were investigated.Result: There was obvious difference between iso group and NS control group.Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities in myocardial tissue of iso group were much weaker than those in the controls
while Hyp content
indexes of heart or left ventricle were increased.Administrated with Gen
those changes were reversed.Conclusion: Gen has a protection on rat’s myocardial hypertrophy caused by iso
and its mechanism probably comes from promoting Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities and decreasing Hyp content.
