Fig. 6. Changes in total WBC counts, differential counts, MPO activity and cytokine content in BALF. After infection with H9N2 virus with or without carnosine treatment, mice were sacrificed and their lungs were lavaged. Cells in the BALF were collected and cytospin preparations were made. (a) Total WBCs (i), macrophages (ii), lymphocytes (iii) and neutrophils (iv) in BALF were analysed. (b) MPO activity, and [c(i)] TNF-α and [c(ii)] IL-1β in BALF were determined at the indicated time points. The mean ± sd (n = 5) at each time point is shown. *P < 0.05; **P < 0.01 compared with H9N2.
