A leukocyte can be compared to an amoeba because of its mobility capacities. True False Choose among the following list, the disease that is not considered autoimmune: glomerulonephritis myasthenia gravis eczema rheumatoid arthritis

Solution

Question 40. Amoeba is a single celled organism having well developed nucleus. An amoebocyte refers to any cell capable of moving like amoeba. Leuckocytes /white blood cells can move like amoeba and can engulf particles. In this regard the leukocyte can be compared to amoeba. So answer is True.

Question 41. An autoimmune disease refers to a condition caused by an abnormal immune response to a normal body part. Some 80 types of autoimmune diseases have been reported so far.

Glomerulonephritis / glomerular nephritis, refers to an inflammation of glomerulus, the functional unit of the kidneys. It is the most common form of autoimmune kidney disease caused either by direct attack or by deposition of immune complexes (aggregates containing autoantibodies and the binding proteins). The condition leads to gradual loss of filtering capacity and functional capability of the kidneys.

Eczema is not directly caused by an autoimmune disorder. Atopic dermatitis, the most common type of eczema, stems from an immune system imbalance. It is a mild skin disease characterized by patches of dry, itchy skin which worsen and erupt into rash as they are scratched. People with atopic dermatitis have low levels of a protein which is needed to promote healthy immune system function. The deficiency of this protein makes the skin more susceptible to infection.

Rheumatoid arthritis (RA) is a long-term autoimmune disorder affecting the joints. It causes swollen, stiff painful joints especially of the wrist and hands. It also leads to low RBC count, inflammation around the lungs, and the heart. It is caused by a combination of genetic and environmental factors.

Myasthenia gravis (MG) is an autoimmune disease in which the antibodies block or destroy nicotinic acetylcholine receptors at the junction between the nerve and muscle, preventing nerve impulses from triggering muscle contractions. It is a long term neuromuscular disease that leads to varying degrees of skeletal muscle weakness. The muscles of the eyes, face, and food pipe are the most commonly affected.

So the answer is Eczema.
