Effect of intramyocardial (P)RR gene delivery on cardiac function in normal adult rat heart.

<p>Adenoviral gene construct expressing (P)RR and LacZ were injected into LV free wall and echocardiographic measurements were performed at 3 days, 1 week and 2 weeks after gene transfer. The results are expressed as mean±SEM (n = 5 to 10).</p>*<p><i>P</i><0.05,</p>**<p>P<0.01 versus LacZ (Student's t-test).
