Total salvianolic acid improves ischemia-reperfusion-induced microcirculatory disturbance in rat mesentery

Figure 1 The protocol of the experiment. The saline and total salvianolic acid (TSA) was continuously infused through the left jugular vein in all groups. Solid arrow represents the infusion with saline to the rat; Dotted arrow represents the infusion with TSA to the rat. -20 min represents the time point of 10 min before ischemia; -10 min represents the time point of the beginning of ischemia; 1, 10, 20, 30, 40, 50 and 60 min represent the time point of 1, 10, 20, 30, 40, 50 and 60 min after reperfusion. I: Ischemia; R: Reperfusion.
