The following chemical mediator is a product of arachidonic acid metabolism by cycloxygenase pathway

LXA4
LXB4
5HETE
PGH2

Correct Answer

A. PGH2

Explanation

PGH2 is the correct answer because it is a product of arachidonic acid metabolism by the cyclooxygenase pathway. Arachidonic acid is converted into prostaglandin H2 (PGH2) by the enzyme cyclooxygenase. PGH2 is then further metabolized into various prostaglandins, thromboxanes, and prostacyclins, which play important roles in inflammation, blood clotting, and other physiological processes in the body.

The ductus arteriosus is derived from the following aortic arch

3rd
4th
5th
6th

Correct Answer

A. 6th

Explanation

The ductus arteriosus is a fetal blood vessel that connects the pulmonary artery to the descending aorta. It allows blood to bypass the lungs since they are not yet functional in the womb. The ductus arteriosus is derived from the 6th aortic arch, which is one of the paired embryonic structures that give rise to the major arteries of the head and neck.

The opportunistic fungi which produces mycotoxins is

Aspergillus flavus
Penicillium marneffi
Allescheria boydii
Phialophora jeanselmei

Correct Answer

A. Aspergillus flavus

Explanation

Aspergillus flavus is a type of opportunistic fungi that is known to produce mycotoxins. Mycotoxins are toxic compounds produced by certain fungi that can contaminate food and feed, posing a risk to human and animal health. Aspergillus flavus is particularly associated with the production of aflatoxins, which are potent carcinogens and can cause liver damage. Therefore, Aspergillus flavus is the correct answer in this case.

In the life cycle of malaria parasite, the definitive host is

Mosquito
Man
Pig
Sandfly

Correct Answer

A. Mosquito

Explanation

In the life cycle of the malaria parasite, the definitive host refers to the organism in which the parasite reaches sexual maturity and reproduces. The correct answer is mosquito because it acts as the definitive host for the malaria parasite. Mosquitoes become infected with the parasite when they feed on the blood of an infected human. Inside the mosquito, the parasite undergoes sexual reproduction and produces new forms called sporozoites. These sporozoites are then transmitted to humans when the infected mosquito bites them, continuing the life cycle of the malaria parasite.

Lipschutz inclusion bodies are seen in infections caused by

Herpes virus
Vaccinia virus
Hepatitis A virus
Hanta virus

Correct Answer

A. Herpes virus

Explanation

Lipschutz inclusion bodies are typically observed in infections caused by the Herpes virus. These inclusion bodies are eosinophilic intranuclear inclusions that can be found in infected cells. They are composed of viral proteins and nucleic acids and are characteristic of Herpes virus infections. Inclusions bodies are often used as diagnostic markers for identifying the presence of specific viruses in infected tissues.

Benign prostatic hyperplasia first develops in

Periurethral transition zone
Peripheral zone
Central zone
Anterior fibromuscular stroma

Correct Answer

A. Periurethral transition zone

Explanation

Benign prostatic hyperplasia (BPH) is a condition characterized by the enlargement of the prostate gland. The periurethral transition zone refers to the area of the prostate gland where the urethra passes through. This zone is responsible for the growth and development of the prostate gland. Therefore, BPH first develops in the periurethral transition zone as it is the region where the prostate gland undergoes hyperplasia, leading to the enlargement of the gland and subsequent symptoms associated with BPH.

A 60-year old patient with a past history of treated pulmonary TB presents with massive hemoptysis. What is the most likely cause for hemoptysis?

Pulmonary amyloidosis
Aspergilloma
Broncholith
Relapse of TB

Correct Answer

A. Aspergilloma

Explanation

Infection of inactive tubercular cavities by Aspergillus fumigatus gives rise to solid mass like lesions inside the cavity (aspergilloma/mycetoma or fungus ball).

10.

Identify the condition.

Acquired pulmonary alveolar proteinosis
IPF
Pemphigus vulgaris
Molluscum contagiosum

Correct Answer

A. Acquired pulmonary alveolar proteinosis

Explanation

Acquired pulmonary alveolar proteinosis is a condition characterized by the accumulation of surfactant in the alveoli of the lungs, leading to impaired gas exchange. This condition is acquired, meaning it is not present at birth but develops later in life. IPF (idiopathic pulmonary fibrosis) is a different condition characterized by progressive scarring of the lung tissue. Pemphigus vulgaris is an autoimmune disorder that affects the skin and mucous membranes. Molluscum contagiosum is a viral skin infection. Therefore, the correct answer is Acquired pulmonary alveolar proteinosis, as it is the only option that matches the given description.
