Genes Induced by Panax Notoginseng in a Rodent Model of Ischemia-Reperfusion Injury

Figure 1

Brain tissue samples of rats from each group. (a) Sham group, (a1) cerebral vessels are abundant and clearly visible, (a2) brain tissue is full and symmetrical. (b) MCAO group treated with saline, (b1) blood vessels around the infarction show exudation, blocked blood vessels are seen to be collapsed and atrophied, and (b2) brain tissue is swollen and white. (c) MCAO group treated with PN, (c1) blood vessels around the infarction are mostly new, with less exudation than MCAO group and (c2) brain tissue is not swollen obviously. The yellow lines indicate the infarct area. Similar experiments were performed at least 5 times.
