FA increased cGMP levels. C57BL/J male mice were treated intraperitoneally with normal saline or FA (100 mg/kg) 12 h before and 12 h after intratracheal administration of LPS (5 mg/kg). cGMP content was detected by ELISA kit. **P < 0.01, compared with Control group; &&P < 0.01, compared with LPS group, n = 4–5
