Fig. 4. Effect of carnosine on pulmonary capillary permeability of BALB/c mice infected with H9N2 SIV. BALB/c mice were inoculated intranasally with a dose of H9N2 SIV (1 × 102 MID50) and treated with carnosine (10 mg kg− 1). At the indicated time, (a) EBD in lung lysates and (b) protein in BALF was evaluated for pulmonary capillary permeability. The mean ± sd (n = 5) at each time point is shown. *P < 0.05; **P < 0.01 compared with H9N2.
