Figure 3. VBP15 reduces acute allergic lung inflammation.

Figure 3

OVA-challenged mice were either left untreated or treated with oral doses of prednisone, VBP15 (20 mg/kg), or cherry syrup alone daily for 6 days. A group of non-challenged mice (naïve) was included in order to assess basal inflammatory parameters. Perfused whole lungs were processed for histological analysis and stained with H&E (A) or PAS (B). Images (10× magnification) represent areas of tissue surrounding bronchioles. Arrows on H&E sections indicate inflammatory foci. Percentage of PAS positive airways were counted via bright field microscopy (C). Bar graph represents mean (±SE)% PAS positive airways. *p<.05; **p<0.01 compared to the vehicle control group with n = 5 mice per group. IL-13 (D) and RANTES (E) were measured in BAL fluid by flow cytometric bead array. Bar graphs represent mean (±SE) cytokine concentration values. *p<.05; **p<0.01 compared to syrup group with n = 5 mice per group.
