Figure 2: Effects of P6 EA on Cx43 mRNA expression in a rat model of droperidol-induced QTc prolongation. (a) Representative Cx43 mRNA of rat left ventricle tissues at 120 min after droperidol i.v. with the absence and presence of P6 EA before treatment. (b) Quantitative densitometric analysis of Cx43 mRNA with GADPH as an internal standard. All values are expressed as mean ± SD; versus droperidol group (D), versus control group (C). C: control group (); D: droperidol group (0.13 mg/kg, ); and E: electroacupuncture on P6 + droperidol ().
