Scleritis (inflammation of sclera) is a strong indication of the underlying medical problem. It can be due to fungal, viral or parasitic infection, trauma, exposure to chemicals, poisonous gases or due to post-surgical complications.
Mast cells are granulated cells typically found in connective tissue. These cells mediate immune responses to foreign particles. In particular, they release large amounts of histamine and enzymes in response to antigen recognition.
To answer that question, first you have to know what histamines are. In the most basic sense, histamines are chemicals produced during any allergic response. When an allergen triggers the immune system, mast cells (a type of white blood cells) release histamines as part of the inflammatory immune reaction.o answer that question, first you have to know what histamines are.
