Mast cells and macrophages isolated from sensitized rats are unequivalent producer of enzymes in systems in vitro. Allergen intensifies exocytosis of acid phosphatase in them but the activity of allergen-induced enzyme secretion by macrophages ++ in immunized rats is lower than the activity of spontaneous secretion of acid phosphatase in suspensions of macrophages + in nonimmunized rats. Macrophages rather than mast cells show the ability for exocytosis of C4-gamma-glutamyltranspeptidase, leukotriene++ catabolism enzyme. Cocultivation of immune macrophages with syngeneic mast cells in the presence of allergen is followed with sharp depression of the activity of this enzyme secretion, that can create conditions for prolongation of eicosanoid effects in allergy.

Asthma is a common chronic inflammatory disorder of the airways associated with hyperresponsiveness, reversible airflow limitation and respiratory symptoms.1 All patients with asthma are at risk for exacerbations that may range from mild to life threatening. Different triggers cause asthma exacerbation by inducing airway inflammation and/or provoking bronchospasm. Allergen-induced bronchospasm results from IgE-dependent release of mediators including histamine, prostaglandins and leukotrienes.2 Opiates are commonly used to treat chronic pain.3 Although hypersensitivity to opiates or accumulation of opiates can cause respiratory depression, opiates are also used in the management of cough and dyspnoea associated with advanced COPD and heart failure.4(,)5 Here, a report is presented on a patient who developed persistent exacerbation of underlying stable asthma after initiating fentanyl transdermal therapy for chronic low back pain. He underwent extensive investigations and a detailed reassessment of history, especially medication history, led to the possible causative factor; once recognised, removal of the offending agent (fenatnyl) resulted in complete improvement in his symptoms within 72 h.
