Differentiate between the following:
Eosinophil and Basophil
Eosinophil and Basophil
✓
Answer
| EOSINOPHIL | BASOPHIL |
| These cells have bilobed nucleus, where each lobe is connected by a thin strand. | A basophil has two or more lobes in the nucleus. |
| The cytoplasmic granules stain orange-red with acid dyes (eosin). Because of this affinity for acidic dyes, they are also called acidophils. | Basophil has an affinity for basic dyes and stains blue-black with them. |
| Their normal count is 60-300 per ml. of blood, about 2 to 5% of the total WBCs count. | Their number ranges from 35 to 100 per ml of blood, about 0.5 to 1% of the total WBC count. |
| Increase in the number of eosinophils in blood is called eosinophilia. It is mainly due to parasitic infection. | It produces a chemical (histamine) which dilates blood vessels making their wall leaky for other leucocytes to fight germs. |
| Eosinophils engulf particles formed by antigen- antibody reaction. | t prevents clotting of blood in the blood vessels, and seratonins, which constrict blood vessels. |
