General Pharmacology

• Systemic Inflammatory Response in Neonatal Farm Animals:
• Neonatal septicemia (joint ill, navel ill, colisepticemia) in calves, foals, and piglets results from opportunistic bacterial invasion (e.g., E. coli, Salmonella) following failure of passive transfer (FPT) of colostral immunoglobulins.
• Cardiovascular and Thermoregulatory Signs:
• The release of pyrogenic cytokines (IL-1, TNF-$\alpha$) and bacterial endotoxins (LPS) resets the hypothalamic thermostat, producing marked elevated body temperature (pyrexia / hyperthermia) in early stages, accompanied by depression, injected scleral vessels, and loss of suckle reflex.
• nalysis:
• (Elevated body temperature): Correct diagnostic clinical sign.

Correct option: (2) Elevated body temperature

• Pharmacodynamics of Antacids:
• Antacids (aluminum hydroxide, magnesium hydroxide, calcium carbonate) are basic compounds that chemically react with gastric hydrochloric acid ($HCl$) to form neutral salts and water.
• By instantly raising intragastric pH above $3.5 - 4.0$, antacids neutralize free acidity and inactivate proteolytic pepsin.
• Their primary and most immediate clinical utility is the prompt relief of ulcer pain within minutes of administration.
• (Definitive ulcer healing and relapse prevention are achieved with H2-receptor antagonists or proton pump inhibitors like omeprazole).
• nalysis:
• (Prompt relief of pain): Correct.

Correct option: (1) Prompt relief of pain

• Comparative Anatomy of Mammalian Uteri:
• Simple Uterus (A): Single uterine body without uterine horns; characteristic of Primates (humans). (Correct match).
• Duplex Uterus (D): Two completely separate uterine horns, two distinct uterine bodies, and two separate cervices opening into the vagina; characteristic of Rodents (rats, guinea pigs) and Lagomorphs (rabbits). (Correct match).
• Bicornuate Uterus: Single cervix, small body, long horns (Sow, Bitch, Mare).
• Therefore, pairs A and D are correctly matched.
• nalysis:
• (Only A & D): Correct.

Correct option: (3) OnlyA&D
