  4. All of the above

Show answer
Correct Option: D
Explanation:
The classic symptoms of eczema are: itching - this is the worst aspect because it can make the person scratch causing further rawness of the skin and possible infections to develop; redness - caused by extra blood flowing through the blood vessels in the skin in the affected area; a grainy appearance to the skin, caused by tiny fluid filled blisters just under the skin called vesicles; weeping when the blisters burst, either by themselves or because of scratching, and the fluid oozes on to the surface of the skin; crusts or scabs that form when the fluid dries; dry, scaly skin - this may be the result of the disease or it may also be the natural skin type of the family; dry skin can be a predisposing factor to developing eczema; pale patches of skin may appear because eczema can disturb the production of pigment which controls skin colour; lichenification - a leathery, thicker skin area in response to scratching.  
Therefore, the correct answer is option B.

  2. Histamine

  3. Immunoglobulins

  4. None of the above

Show answer
Correct Option: B
Explanation:

Allergies are the reactions or the response given to the antigens which are in the form of particles. Allergy is also termed as hypersensitivity. The cells release IgE antibodies, histamines and other cytokines which manifest the symptoms of the reaction. When the allergen is encountered, the mast cells and basophils undergo degranulation which releases histamine. Histamine is the inflammatory agent. 

Thus, the correct answer is option B.

  3. Asthma

  4. All of the above

Show answer
Correct Option: D
Explanation:

Allergies are the reactions or the response given to the antigens which are in the form of particles. Allergy is also termed as hypersensitivity. The cells release IgE antibodies, histamines and other cytokines which manifest the symptoms of the reaction. Allergy may result in urticaria which is the development of skin rash with reddening and swelling of the regions. The allergen results in stimulation of mucus secretion and sneezing which causes rhinitis. The common example of allergy is asthma which results in the constriction of the bronchi and shortness of breath due to the blocking of the airway.  

Thus, the correct answer is option D.

Correct Option: C
Explanation:
  • Antihistamines are drugs which are used to treat allergic rhinitis and other allergies. Antihistamines can give relief when a person has nasal congestion, sneezing, or hives because of pollen, dust mites, or animal allergy. Histamine is mostly responsible for allergic reactions. Antihistamines block the action of histamines.
  • A steroid is a biologically active organic compound. Steroids such as corticosteroids are used in the treatment of allergic reactions by reducing inflammation associated with allergies. They prevent and treat nasal stuffiness, sneezing, and itchy, runny nose due to seasonal or year-round allergies. They can also decrease inflammation and swelling from other types of allergic reactions
  • So, the correct answer is 'Allergy'.
