In this study patients who have clinical sign and symptoms of rhinitis (nasal congestion, rhinorrhea, sneezsing, itchy nose, headache, earache, Itchy throat, snoring or postnasal drip), after diagnosis by specialist of allergy, will enter the study. Next, we will make an interview with patients and will explain the situations of the study to patients. If patients Satisfy and desire the study, they will enter the study. From each patient, before treatment and after one month treatment, 5 ml blood will be taken. Treatment will be done in one month by use of anti-histamine (Fexofenadine) and Intranasal corticosteroid (fluticasone propionate). Blood samples will be transferred to CBC vials containing anti coagulant (EDTA) and then will be transferred to the laboratory as quickly as possible. Then, using RNA extraction kit, RNA will be extracted from peripheral blood cells of sample bloods. Next by use of Reverse transcriptase enzyme, the extracted RNA will be transcribed to complementary DNA (cDNA) and then they will be stored in -20 ºC until the last step. Then the level of expression of transcription factors gene: GATA-3, Foxp3 and RORγt in all prepared cDNA will be measured, in relative measurement, by use of Real-time PCR and sybergreen method.
