Eosinophilic leukocytes were detected 54.32%, in 81 samples of sputum and 33.33%, in 36 nasal smears of the patients with allergic bronchial asthma and rhinitis by using Giemsa and Eosin Y-Methylene blue stains. We think that Eosin Y-Methylene blue probably is better than Giemsa stain, in the staining of eosinophilic leucocytes because of its convenience in detection.
