Figure Lengend Snippet: Inflammatory cell counts in nasal and bronchoalveolar lavage fluids (NALF and BALF) following single or combined exposure to PM2.5, Zn, and formaldehyde in a murine model of allergic rhinitis. (A) Total and differential cell counts, including eosinophils, neutrophils, lymphocytes, and monocytes, were measured in NALF from non-sensitized mice after single intranasal exposure to PM2.5, Zn, or formaldehyde. (B) Total and differential cell counts were assessed in BALF from the same non-sensitized mice following identical single exposures. (C) In ovalbumin (OVA)-sensitized mice, total and differential cell counts in NALF were evaluated after additional intranasal exposure to PM2.5 alone or in combination with Zn or formaldehyde. (D) Total and differential cell counts in BALF were measured in the same OVA-sensitized mice after combined exposures. Inflammatory cells were identified based on morphological characteristics using Diff-Quik staining. Values are presented as mean±standard deviation. NS, not significant. Statistical analysis was conducted with one-way analysis of variance followed by Tukey’s post hoc test. * P <0.05, ** P <0.01, *** P <0.001 vs. OVA or OVA+PM2.5, as indicated.
