It is also known to prevent the release of inflammatory chemicals called basophils and eosinophils from mast cells and white blood cells.
Sensitive patients challenged with an extract of poison ivy orally developed degranulation of circulating basophils within an hour (Shelley & Resnik 1965 ).
Images include basophils, monocytes, eosinophils neutrophils, lymphocytes, and platelets.
However, recent immunohistochemical studies have raised the possibility that neoplastic basophils express significant amounts of tryptase.
Normal blood basophils express only trace amounts of the enzyme.
