Effect of etanercept on body weight, tissue weight, systolic blood pressure and heart rate. (a) Experimental protocol. Control group received DMSO i.p. injection twice per week for 4 weeks and normal saline s.c. injection twice per week for 8 weeks. AA group received AA (3 mg/kg) i.p. injection twice per week for 4 weeks and normal saline s.c. injection twice per week for 8 weeks. AA + ETN group received AA (3 mg/kg) i.p. injection twice per week for 4 weeks and ETN (5 mg/kg) s.c. injection twice per week for 8 weeks. Body weight was measured twice per week for 8 weeks. Blood pressure and heart rate were measured at 0, 4, and 8 weeks after the start of the experiment. (b) Changes in body weight. (c) Heart and kidney weight to body weight ratio. (d) Changes in systolic blood pressure. (e) Changes in heart rate. Values are means ± SEM, n = 8. *** P < 0.001. AA, aristolochic acid; DMSO, dimethyl sulfoxide; ETN, etanercept; BP, blood pressure; HR, heart rate; Ctrl, control.
