Explanation

Aspirin inhibits the cyclooxygenase (COX) enzyme, reducing prostaglandin synthesis.

This action lowers pain (analgesic) and fever (antipyretic).

Explanation

Ovariohysterectomy is removal of ovaries and uterus, used for sterilization, preventing estrous, and pyometra in females.

It cannot prevent prostate cancer, which is a male reproductive organ disease.

Explanation

CPK (Creatine Phosphokinase) is released into the blood during muscle damage, making it a reliable indicator.

It is especially used to diagnose muscle disorders and myocardial infarction.

Explanation

Increased Erythrocyte Sedimentation Rate (ESR) is a non-specific indicator of inflammation or disease.

It is commonly elevated in tuberculosis, malignancies, and nephritis, among other conditions.

Explanation

Uterine prolapse in cattle primarily occurs after difficult or prolonged calving, which weakens pelvic muscles and ligaments.

It often follows straining and trauma during delivery, especially in cases of large calf or twin births.

Explanation

Omeprazole is a proton pump inhibitor (PPI), not an H2-receptor antagonist.

Cimetidine and Ranitidine are classic H2-receptor antagonists.

While Fexofenadine is an H1-receptor antagonist (antihistamine).

Explanation

Magnesium sulfate acts as a muscle relaxant by blocking neuromuscular transmission.

It is used clinically to relieve muscle spasms and prevent seizures in certain conditions.

Explanation

Staphylococcus aureus commonly enters the bovine udder during milking through teat canal contamination.

It is a major cause of mastitis in dairy cattle due to its ability to persist in the udder.

Explanation

Milk fever (hypocalcemia) commonly causes paresis (muscle weakness) immediately after calving in buffaloes and cows.

It results from low blood calcium levels due to sudden demand for milk production.

Explanation

Cardiac muscle cells have very limited ability to regenerate after injury, leading to scar tissue formation.

Fibroblasts, renal tubular cells, and hepatocytes have a higher regenerative capacity compared to cardiac muscle.
