Changes in systolic BP of experimental rats during the 4-week period. a The SHRs were randomly divided into four groups (n = 10 per group). Group 1: SHRs on a wooden board without FIR radiation as the control group (control); group 2: SHRs on a wooden board with FIR radiation (FIR); group 3: SHRs on a normal wooden board with atenolol administration as the positive control group (atenolol); and group 4: SHRs on an FIR-radiated wooden board with atenolol administration (FIR + atenolol). b The WKY rats were randomly divided into two groups (n = 10 per group). Group 1: WKYs on a wooden board without FIR radiation as the control group (control); and group 2: WKY rats on a wooden board with FIR radiation (FIR). Data are mean ± SEM. *p < 0.05 vs. control SHRs, #p < 0.05 vs. SHRs with FIR irradiation
