The effect of famotidine on the mononuclear cell count in the BALF of airway-sensitized rats. OVA-sensitization was associated with a significant elevation in mononuclear cell count present in the BALF, whereas treatment with famotidine led to their significant reduction. A_group, negative control; B_group, positive control (sensitized); C_group, prednisolone; D_group, famotidine; E_group, prednisolone and famotidine; *= denoting statistical significance (P<0.05) in comparison to A_group; a= denoting statistical significance (P<0.05) in comparison to B_group.
