Question
Chapter 29, Problem 3WIO
Summary Introduction
To determine:
The side effects of the drug that kills the mast cells.
Introduction:
Allergens are defined as nonpathogenic substances that are harmless in normal condition but still trigger an immune response in a person. Allergic responses are also called as type I hypersensitivity reaction, and the body produces IgE immunoglobulins in response to the antigen. These antibodies stimulate the release of histamine by the mast cells, and it produces an immune response.

- A child is exposed to poison sumac (a woody shrub) for the first time, but it does not develop any reaction after this first exposure. In subsequent months, he is exposed again to the same plant. Two days after re-exposure, he develops a painful rash. The doctor tells the child's parents that he has allergic contact dermatitis, which is a humoral-related immune response. The doctor assessment is incorrect because A. Poison ivy does not cause contact dermatitis B. This reaction is not a delayed cell-related immunity C. This is an autoimmunity disease D. This is not a humoral response. T cells are responsible for this type of hypersensitivity. E.
