The recovery of baseline ventilation (VE) after sarin exposure in conscious rats. As compared with vehicle (VEH), the moderate- (SM) and high-dose sarin (SH)-induced reduction of baseline VE and tidal volume (VT) 2 h after exposure was recovered 1 day after sarin exposure. D1–D5 represents the tests applied 1, 2, and 5 days after exposure. Mean ± SE; n = 12, 8, and 8 for VEH, SM, and SH animals, respectively. * P < 0.01, SH vs. VEH and SM groups.
