Question
Type I hypersensitivities are set in motion when which of the following binds to mast cells? A. IgG B. IgD C. IgE D. IgM Systemic release of which of the following inflammatory mediators can lead to anaphylactic shock as a consequence of a Type I hypersensitivity? A. Histamine B. Leukotrienes C. Prostaglandins D. All of the above Which of the following is a sign or symptom of a Type I hypersensitivity? A. Redness or rash B. Increased fluids leading to watery eyes and runny nose C. Smooth muscle contraction D. All of the above A Type II hypersensitivity is also called which of the following? A)Cell-mediated hypersensitivity B) Humoral hypersensitivity C) Cytotoxic hypersensitivity D) Allergy Which of the following occurs during a Type II hypersensitivity reaction? A) Antibodies attach to person's own cells. B) T cells attack a person's own cells. C) IgE attaches to T cells and inflammatory mediators are released. D) Soluble antigen-antibody complexes forExplanation / Answer
89-C) IgE
It is the difference between the normal infection and the hypersensitivity 1 that IgE is produced is produced in hypersensitivity instead of IgG IgA and IgM in the infectious immune response.
So option A B and D are wrong.
90-D) all of the above.
Histamine is primary produced as granules and then release of these granules is followed quickly by increased synthesis from membrane arachidonic acid of prostaglandins and leukotrienes that have an additional role in anaphylactic shock that will lead to hypersensitivity 1
91)-D) all of the above
Because all the symptoms mentioned are because of IgE production and that is what happenes in the hypersensitivity 1 reaction.
92-C) cytosolic hypersensitivity.
A is wrong because cell mediated hypersensitivity is type 4 hypersensitivity.
B is wrong because humoral hypersensitivity is type 1 hypersensitivity.
D is wrong because immune complex hypersensitivity is type 3 hypersensitivity.
