marasmus

A.
marasmus
Prolonged starvation causes marasmus due to a generalised wasting of the body because of both energy and protein deficiency. The body becomes lean and weak, eyes depressed and skin wrinkled.
Which one of the following techniques is safest for the detection of cancer?
Magnetic Resonance Imaging (MRI)
Radiography (X -ray)
Computed Tomography (CT)
Computed Tomography (CT)
A.
Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging (MRI) is non -invasive technique, which uses strong magnetic field and provides information about chemistry, metabolic and biochemical data with a tissue without time-consuming chemical analysis. It is the safest technique for the detection of cancer since it does not utilise radiations and therefore, does not cause any side effect.
The histopathological study is not safe as it is invasive technique while radiography and computed Tomography (CT) use harmful X -rays.
Which one of the following cannot be used for the preparation of vaccines against plague?
Formalin - inactivated suspensions of virulent bacteria
Avirulent live bacteria
Synthetic capsular polysaccharide material
Synthetic capsular polysaccharide material
C.
Synthetic capsular polysaccharide material
Synthetic capsular polysaccharide vaccines are available for the treatment of pneumonia and meningitis. Vaccines against plague are prepared from the suspensions of attenuated or heat-killed virulent bacteria or avirulent live bacteria.
A person suffering from a disease caused by Plasmodium experiences recurring chill and fever at the time when the
sporozoites released from RBCs are being rapidly killed and broken down inside spleen
trophozoites reach maximum growth and give out certain toxins
Parasite after its rapid multiplication inside RBCs ruptures them, releasing the stage to enter fresh RBCs
Parasite after its rapid multiplication inside RBCs ruptures them, releasing the stage to enter fresh RBCs
C.
Parasite after its rapid multiplication inside RBCs ruptures them, releasing the stage to enter fresh RBCs
In malaria, chill and fever are due to the release of a toxic substance haemozoin, formed by the breakdown of haemoglobin present in RBCs. It will be released after the rupture of RBCs in erythrocytic schizogony.
A health disorder that results from the deficiency of thyroxin in adults and characterised by
(i) a low metabolic rate
(ii) increase in body weight
(iii) tendency to retain water in tissue is
hypthyroidism
simple goitre
myxoedema
myxoedema
C.
myxoedema
Myxoedema (Gulls disease) occurs due to the deficiency of thyroxine in adults, it causes low BMR (by 30-40%), low body temperature, tendency to retain water in tissue, reduced heart rate, pulse rate, blood pressure and cardiac output, low sugar and iodine level in blood, muscular weakness and oedema (accumulation of interstitial fluid that causes the facial tissues to swell and look fluffy).
