Effects of ketamine on inflammatory scores in lung tissues from ovalbumin-sensitized and -challenged rats. Lungs were sampled after measurement of airway reactivity and scored under the light microscope at a magnification of ×40. Bars represent mean ± SEM (n = 6–8/group). # P < 0.05 vs. PBS control, * P < 0.05 vs. OVA control. The groups are as shown in Figure 1.
