Plasma bradykinin levels of experimental rats after the 4-week treatments. WKYs: WKYs on a wooden board without FIR radiation; CL: SHRs on a wooden board without FIR radiation; FIR: SHRs on a wooden board with FIR radiation; atenolol: SHRs on a normal wooden board with atenolol administration; FIR + atenolol: SHRs on an FIR-radiated wooden board with atenolol administration. Data are mean ± SEM from n = 10 animals per treatment group. *p < 0.05 vs. control SHRs, #p < 0.05 vs. SHRs with FIR irradiation, †p < 0.05 vs. WKY group
