उत्तर
In severe allergic reactions, the antigen-antibody reaction on mast cells causes them to burst and release large amounts of histamine. This causes dilation of capillaries and a sudden violent reaction called anaphylactic shock, which may cause choking and can be fatal (e.g., a single bee sting or a dose of penicillin).
