Primary Mechanism Study of Panax notoginseng Flower (Herb) on Myocardial Infarction in Rats
Effects of drugs on mean MVC (mean microvessel count) after 2 weeks of ischemia (a). After myocardial infarction and administration, heart tissues were collected and subjected to an immunofluorescent assay on SMA (green) and VWF (red) antibodies. Under the fluorescence microscope of 400 magnified fields, the minimal vessels were pictured and the numbers of vessels were counted (b). Sham: sham group; MI: MI control group; FD500: Panax notoginseng flower decoction (500 mg/kg/d); FD1000: Panax notoginseng flower decoction (1000 mg/kg/d); MI + Bet: Betaloc (10 mg/kg/d). Mean minimal vessel count is expressed as mean ± SD (). and vs sham group; and vs myocardial infarction control group.
