Fig 4 (a) Electron micrograph of a human cutaneous mast cell from a rocuronium-induced wheal. The cell outline is well defined, and the electron-dense cytoplasmic granules that store mast cell mediators are well delineated (arrow), without any evidence of degranulation. Note the collagen bundles around the mast cell (arrow). (b) Electron micrograph of a human cutaneous mast cell from a cisatracurium-induced wheal. Most of the cytoplasmic granules are swollen, and demonstrate varying degrees of decreased density and loss of organization consistent with ongoing degranulation (arrow). Note the collagen bundles around the mast cell (arrow). British Journal of Anaesthesia 2000 85, 844-849DOI: (10.1093/bja/85.6.844) Copyright © 2000 British Journal of Anaesthesia Terms and Conditions
