You read a report which was handwritten in a patient's medical notes who you suspect has inflammatory bowel disease.

ব্যাখ্যা
The appearance of 'cobblestoning' and 'rose thorn ulcers' are radiological descriptions, seen in Crohn's disease, obtained from barium follow- through investigations of the ileum. Lower GI endoscopy is preferred in establishing a diagnosis of IBD (either Crohn's or UC) because the operator is allowed direct visualization of the bowel and biopsies may be taken; skip lesions can be seen on direct visualization but the appearance of 'rose thorn ulcers' have only been described in barium radiograpy studies.

Acute Kidney Failure After Transfusion Reactions
One of the most lethal effects of transfusion reactions is kidney failure, which can begin within a few minutes to a few hours and continue until the person dies of acute renal failure.
The kidney shutdown seems to have three causes:
1. The antigen-antibody reaction of the transfusion reaction releases toxic substances from the hemolyzing blood that cause powerful renal vasoconstriction
2. Loss of circulating RBCs in the recipient, along with production of toxic substances from the hemolyzed cells and the immune reaction, often. cause circulatory shock. The arterial blood pressure falls very low, and renal blood flow and urine output decrease.
3. If the total amount of free hemoglobin released into the circulating blood is greater than the quantity that can bind with haptoglobin (a plasma protein that binds small amounts of hemoglobin), much of the excess leaks through the glomerular membranes into the kidney tubules.

ঘ) Chronic renal failure
উত্তর
সঠিক উত্তর: ঘ
ঘ) Chronic renal failure
ব্যাখ্যা
Explanation-
★Ca2+ deficiency (low Ca2+ diet or hypocalcemia) activates 1α-hydroxylase, which catalyzes the conversion of vitamin D to its active form, 1,25-dihydroxycholecalciferol. Increased parathyroid hormone (PTH) and hypophosphatemia also stimulate the enzyme. Chronic renal failure is associated with a constellation of bone diseases, including osteomalacia caused by failure of the diseased renal tissue to produce the active form of vitamin D.

ব্যাখ্যা
Inhibition of Na+,K+-adenosine triphosphatase (ATPase) leads to an increase in intracellular Na+ concentration. Increased intracellular Na+ concentration decreases the Na+ gradient across the cell membrane, thereby inhibiting Na+–Ca2+ exchange and causing an increase in intracellular Ca2+ concentration. Increased intracellular Na+ concentration also inhibits Na+–glucose cotransport.

The premotor and motor cortices plan and execute movements. Lesions of the substantia nigra, a component of the basal ganglia, result in tremors, lead-pipe rigidity, and poor muscle tone (Parkinson disease).

ব্যাখ্যা
The “no-reflow” phenomenon refers to the inability to reperfuse myocardial tissue despite the reopening of the infarct-related artery. No-reflow often happens in acute myocardial infarction patients during primary percutaneous coronary intervention (PCI), which has a strong negative impact on clinical outcome, negating the potential benefit of primary PCI. No-reflow is associated with a higher rate of mortality and early postinfarction complications.

Which of the following inhibits the secretion of growth hormone by the anterior pituitary?
সঠিক উত্তর: ঘ
ঘ) Somatomedins
উত্তর
সঠিক উত্তর: ঘ
ঘ) Somatomedins
ব্যাখ্যা
Explanation-
★ Growth hormone is secreted in pulsatile fashion, with a large burst occurring during deep sleep (sleep stage 3 or 4). Growth hormone secretion is increased by sleep, stress, puberty, starvation, and hypoglycemia. Somatomedins are generated when growth hormone acts on its target tissues; they inhibit growth hormone secretion by the anterior pituitary, both directly and indirectly (by stimulating somatostatin release).

Which of the following substances or combinations of substances could be used to measure interstitial fluid volume?
সঠিক উত্তর: ঘ
ঘ) Inulin and radioactive albumin
উত্তর
সঠিক উত্তর: ঘ
ঘ) Inulin and radioactive albumin
ব্যাখ্যা
Interstitial fluid volume is measured indirectly by determining the difference between extracellular fluid (ECF) volume and plasma volume. Inulin, a large fructose polymer that is restricted to the extracellular space, is a marker for ECF volume. Radioactive albumin is a marker for plasma volume.
