Although it has been generally considered that histamine plays a principal role in the anaphylactic reaction, no hypothesis to explain it has been confirmed experimentally. This investigation was attempted to reexamine the significance of histamine in the anaphylactically induced dynamic responses. The results obtained are as follows : Histamine was released from the isolated atrial and ventric...
Anaphylactic shock is a severe allergic reaction involving multiple organs including the bronchial and cardiovascular system. Most anaphylactic mediators, like platelet-activating factor (PAF), histamine, and others, act through G protein-coupled receptors, which are linked to the heterotrimeric G proteins G(q)/G(11), G(12)/G(13), and G(i). The role of downstream signaling pathways activated by...
Yam (Dioscorea opposita) is commonly consumed in East Asia, but allergic reaction to this plant food is rare. To date, there is no report of anaphylactic reaction after ingestion of cooked yam. We described 3 cases with anaphylaxis after eating boiled yam and 1 present with oral allergy syndrome as well. Basophil activation test in patients showed positive reactivity to boiled yam extract. In i...
Anaphylaxis is an unanticipated severe allergic reaction that can occur during a surgical procedure. A patient is exposed to myriad foreign substances during surgery, such as anesthetic drugs, blood products, and surgical materials, including a commonly used hemostatic agent called Avitene Microfibrillar Collagen Hemostat. Anaphylaxis is the most severe immune-mediated reaction, and it generall...
Adverse drug reactions are a common clinical problem. It has been estimated that 6% to 15% of hospitalized patients experience some sort of adverse drug reaction. Clinical manifestations of adverse drug reactions include skin rash; a serum sickness-like reaction; drug fever; pulmonary, hepatic, and renal involvement; and systemic anaphylaxis. Many of these adverse events are not immunologically...
