The Inhibition Effects of Shenmai Injection on Acetylcholine-Induced Catecholamine Synthesis and Secretion by Modulating Nicotinic Acetylcholine Receptor Ion Channels in Cultured Bovine Adrenal Medullary Cells

Figure 2

Effects of combinations of SMI and several inhibitors of α-subunit sites in the nAChR ion channels on catecholamine secretion induced by 300 μM ACh. Data are expressed as mean ± SEM based on three independent experiments each performed in triplicates (n = 6 per group). , compared with 300 μM ACh alone and , compared with 300 μM ACh plus SMI.
