Anaphylaxis is known as a type I hypersensitivity reaction and occurs within 15 to 30 minutes of being exposed to the antigen (foreign organisms or substance). Sometimes a severe reaction can occur within seconds. This reaction is mediated by immunglobulin E (IgE), which is a type of antibody...
What is a hypersensitivity reaction? Classify different types of hypersensitivity reactions. Describe the symptoms What are some differences and/or similarities in the type of inhibition caused by heat, acid or base, and heavy metal ions on enzyme activity. ...
Gluten is not a common food allergy, and true gluten hypersensitivity, or celiac disease, is mediated by another type of antibody (not IgE but IgA) and also leads to different symptoms (including chronic abdominal discomfort, nausea, vomiting, change in stool, and anemia). Medications: Although...
It has also occasionally caused hypersensitivity reactions and a deficiency of platelets, which are the blood components responsible for clotting. Either of these reactions can be fatal. Quinine is also associated with a cluster of symptoms called cinchonism (nausea, vomiting, headaches, and deafness...
The typical clinical features are motor weakness, cognitive changes, and hypersensitivity to stimuli. On physical examination, affected individuals are found to have a cherry-red spot on the macula . Management is supportive as there is no cure for this disease. Sickle cell disease : the most ...
Heterologous antisera, streptokinase, and insulin are examples of complex antigens capable of eliciting hypersensitivity reactions. Most drugs have a smaller molecular weight (less than 1,000 daltons), but may still become immunogenic by coupling with carrier proteins, such as albumin, to form ...
Define the following terms: acquired immunity, cell-mediated immunity, humoral immunity, hypersensitivity. What are the events occurring in immunity in type I hypersensitivities? Identify some of the major mechanisms that pathogens use to resist the immune system a...
What are the signs and symptoms of hemophilia? formation (collection of blood in tissues) may occur in the muscles, soft tissues, and organs in the body. An intracranial hematoma (formed around the brain) may be life-threatening. Excessive bleeding after minor surgical procedures, such as remov...
