| dc.subject | Objective: We investigate whether lycopene has a protective effect in an experimental rat model of allergic rhinitis. Methods: Experimental animals (65 rats) were randomized to 7 groups (Sham-Control, Lycopene 10 mg/kg/day, Lycopene 20 mg/kg/day, Intranasal lycopene drops, Intranasal steroid, Corn oil, Allergic Rhinitis). Rats were sensitized by administering of ovalbumin intraperitoneally and intranasally. In addition to ovalbumin; lycopene, corn oil and steroids were given to the relevant groups. Nasal symptom scores of the rats were recorded throughout the study. At end of the study, after intracardiac blood sample collection, all rats were sacrificed, and nasal tissues were examined histopathologically. Serum total immunoglobulin E (IgE) and ovalbumin (OVA) specific IgE were studied from all rats before and after the study. Results: There was a statistically significant increase (p < 0.05) in OVA specific IgE values measured before and after the study in all groups except the sham group. In serum total IgE values; there was a statistically significant increase after treatment in allergic rhinitis, corn oil, lycopene 10 mg and intranasal lycopene drops group, but other groups did not show any significant change. Histopathological study with hematoxylin-eosin staining and cyclooxygenase-2 (COX-2), matrix metalloproteinase-9 (MMP-9), vasoactive intestinal peptide (VIP) expression found that lycopene suppresses inflammation with both nasal administration and increased dose. Nasal symptom scores were observed to decrease significantly in all lycopene and steroid groups compared to allergic rihinits and corn groups. Conclusion: It was determined that lycopene were effective in the treatment of allergic rhinitis, and this effect was found to be stronger with increasing doses of lycopene. | |
