Which cells are destroyed by HIV?
thrombocytes
CD4
ESR
CD8
The Correct Answer is B
A. thrombocytes: Platelets (thrombocytes) are not the primary target of HIV; they may be affected secondarily but are not the cells destroyed by the virus.
B. CD4: HIV infects and progressively depletes CD4⁺ T helper lymphocytes, which leads to immune deficiency.
C. ESR: ESR (erythrocyte sedimentation rate) is a laboratory test/value, not a cell type, so it cannot be destroyed.
D. CD8: CD8⁺ cytotoxic T cells are not the primary cells infected by HIV; they may be functionally affected but HIV primarily targets CD4⁺ T cells.

Correct Answer is C
Explanation
A. myelogram: A myelogram is an imaging study in which contrast is injected into the subarachnoid space to visualize the spinal canal on x-ray/CT - it is primarily imaging, not the laboratory analysis of CSF.
B. BUN: Blood urea nitrogen is a blood chemistry test (kidney function) and does not analyze cerebrospinal fluid.
C. lumbar puncture: A lumbar puncture (spinal tap) is the procedure used to collect cerebrospinal fluid for laboratory analysis (cells, glucose, protein, culture, etc.).
D. IVP: An intravenous pyelogram (IVP) is an imaging study of the urinary tract using contrast - unrelated to CSF.
Correct Answer is D
Explanation
A. increased interstitial fluid: Increased interstitial fluid (edema) causes swelling (tumour) rather than the warmth and redness of inflammation.
B. production of complement: Complement proteins contribute to inflammation (opsonization, cell lysis) but are not the direct cause of the warmth/redness.
C. white blood cells in area: Leukocyte accumulation contributes to pain and loss of function but is not the main cause of the heat and redness.
D. increased blood flow: Vasodilation of arterioles increases blood flow to the injured area, producing the local warmth (calor) and redness (rubor).
