FIGURE 3 .

Degree of lung pathology in mice fed control or fish oil diets following influenza infection. Values are means ± SEM, n = 3-6 per time point except d 10, n = 11 (control and fish oil). *Different from control, P < 0.05. Pathology score was as follows: 0, no inflammation; 1+, mild influx of inflammatory cells with cuffing around vessels; 2+, increased inflammation with ∼25–50% of the total lung involved; 3+, severe inflammation involving 50–75% of the lung; and 4+, almost all lung tissue contained inflammatory infiltrates.
