Effects of SF and OMT combination on the lung Wet/Dry (W/D) ratio of PQ intoxication rats. CON, PQ, SF and OMT represent the control group, paraquat group, sodium ferulate group (3.1 mg/Kg/day) and oxymatrine group (6.9 mg/Kg/day), respectively. SF+OMT represents sodium ferulate and oxymatrine combination treatment groups, and the 1.6 + 3.4, 3.1 + 6.9 and 6.2 + 13.8 respectively represent drug administration doses of SF+OMT in the low dose group, middle dose group and high dose group. The lung W/D ratio was determined at 56 h after the PQ injection. Data are expressed as means ± SEM. n = 10 in each group. ^##P < 0.01 compared with the control group. ^*P < 0.05, **P < 0.01 compared with the PQ group
