Tryptase, a neutral protease of human mast cells, is a potentially important indicator of mast cell involvement in various clinical conditions. The current study examined the time course of appearance and disappearance of tryptase in the circulation after an anaphylactic event and the stability of both endogenous and exogenous tryptase in terms of freeze-thawing and temperature. The peak level ...

OBJECTIVES To describe wasp and bee species that sting humans, analyse risk factors and clinical features. METHODS A prospective observational study was conducted on patients presenting to Base Hospital Deniyaya with suspected bee and wasp stings from 2011 to 2013. Data were gathered using a questionnaire and specimens of offending insects collected for identification. When the insect specime...

Stimulation of cells and tissues, whether by mechanical, hormonal, or neurological means, results in the increased biosynthesis of prostaglandins (Ramwell and Shaw, 1970). It has been suggested that one such stimulus is inflammation, in the course of which phospholipases are freed from the lysosomes of phagocytes. These enzymes can cleave phospholipids of the cell membrane to yield arachidonic ...

An elderly beekeeper presented with nephrotic syndrome due to secondary amyloidosis. He developed progressive renal impairment and ultimately required dialysis. The patient had received multiple bee stings per day over seven decades without any allergic reactions. Here, we report secondary amyloidosis associated with recurrent bee venom exposure. KeyworDs Bee sting, kidney, nephrotic, secondary...

Bee stings can cause severe reactions and have caused many victims in the last years. Allergic reactions can be triggered by a single sting and the greater the number of stings, the worse the prognosis. The poisoning effects can be systemic and can eventually cause death. The poison components are melitin, apamin, peptide 401, phospholipase A2, hyaluronidase, histamine, dopamine, and norepineph...
