Figure 5: Effect of tanshinone IIA on the phenylephrine (10 nmol l−1) or KCl (40 mmol l−1)-induced increase of in A7r5 line of rat aortic smooth muscle cells. Changes of in A7r5 cells were measured by fura-2 as described in Section 2. The obtained from A7r5 cells without treatment was  nmol l−1. The data (mean ± SD) were obtained from six experiments.
