Reticulocytosis is seen in -
1) Hemolytic anemia
2) Megaloblastic anemia
3) Aplastic anemia
4) Iron deficiency
General Pathology
Answer: 1
Reticulocytosis is commonly seen in hemolytic anemia, where there is increased production of red blood cells in response to anemia.
A bacterial disease with oral manifestations is
1) Herpes Measles
2) Measles
3) Diphtheria
4) Leishmaniasis
Oral Pathology
Answer: 3
Diphtheria serious bacterial infection that usually affects the mucous
membranes of the nose and throat.
Diphtheria signs and symptoms usually begin 2 to 5 days after a person becomes
infected. Signs and symptoms may include:
A thick, gray membrane covering the throat and tonsils
A sore throat and hoarseness
Swollen glands (enlarged lymph nodes) in the neck
Difficulty breathing or rapid breathing
Nasal discharge
Fever and chills
Tiredness
Skin (cutaneous) diphtheria
A second type of diphtheria can affect the skin, causing pain, redness and
swelling similar to other bacterial skin infections. Ulcers covered by a gray
membrane also may be a sign of skin diphtheria.
Hereditary spherocytosis is due to deficiency -
1) Spectrin
2) Invertin
3) Cytokeratin
4) All of the above
General Pathology
Answer: 1
Hereditary spherocytosis is primarily due to a deficiency of spectrin, a protein that helps maintain the integrity of the red blood cell membrane.
Acrodermatitis enteropathica is due to deficiency of
1. Mercury
2. Zinc
3. Lead
4. Bismuth
Oral Pathology
Answer: 2
Acrodermatitis enteropathica is due to a deficiency of zinc.
Heterozygous sickle cell anemia gives protection against -
1) G6PD
2) Malaria
3) Thalassemia
4) Dengue fever
General Pathology
Answer: 2
Heterozygous sickle cell anemia provides protection against malaria due to the altered red blood cell environment that is less hospitable to the malaria parasite.
Speed at which electron travel in gas tube once released from cathode filament is dependent on
1. Potential difference between electrodes
2. Angle between filament and anoxic target
3. Amount of kilovoltage applied to the circuit
4. Intensity of current applied to target
Oral Pathology
Answer: 1
The speed at which electrons travel in a gas tube is primarily dependent on the potential difference between electrodes.
Scleroderma involves
1. Tightening of oral mucosa and periodontal involvement
2. Multiple palmar keratosia
3. Raynaud"s phenomenon
4. All of the above
Oral Pathology
Answer: 4
Scleroderma involves tightening of oral mucosa, periodontal involvement, and Raynaud's phenomenon.
The primary defect which leads to sickle cell anemia is -
1) An abnormality in porphyrin part of hemoglobin
2) Replacement of glutamate by valine in ?-chain of HbA
3) A nonsense mutation in the ?-chain of HbA
4) Substitution of valine by glutamate in the ?-chain of HbA
General Pathology
Answer: 2
The primary defect in sickle cell anemia is the replacement of glutamic acid by valine in the ?-chain of hemoglobin, leading to the sickling of red blood cells.
