Question

A young boy, when brought a pet dog home, started to complain of watery eyes and running nose. The symptoms disappeared when the boy was kept away from the pet.
1.Name the type of antibody and the chemicals responsible for such a response in the boy.
2.Mention the name of anyone drug that could be given to the boy for immediate relief from such a response.

Answer 1

Hint:
The protein produced by the immune system of the body when it detects a harmful substance called antigens is known as an antibody. The substance that causes a change in the physiology and psychology of a person is known as a drug.

Complete answer:
The boy complained of the symptoms as he was having an allergy. A disease in which the immune system responds abnormally to a foreign material is referred to as an allergy. Allergic reactions are hypersensitivity reactions that occur when the immune system reacts abnormally to natural compounds such as pollen, dust and certain foods.
The IgE type of antibody and chemicals such as histamine and serotonin are released from mast cells that activate this reaction. Immunoglobulin E (IgE) is an antibody formed by the immune system. These antibodies migrate to cells that release chemicals and induce an allergic reaction. This reaction normally produces effects in the nose, mouth, throat, or skin. When you have an allergy, the immune system overreacts to an allergen by generating antibodies called Immunoglobulin E. These antibodies travel to cells that release chemicals and induce an allergic reaction.
The boy can be given drugs such as antihistamine, adrenaline, steroids for immediate relief from such a reaction. They minimize allergy symptoms rapidly, including sneezing, watery eyes, dripping nose, and trouble breathing.

Note: The antibody IgE is found only in mammals. IgE provides immunity to the parasites like helminths. IgE also plays an important role in responses to allergens such as anaphylactic reactions to drugs.
