You are an expert Professor of Forensic Medicine & Toxicology teaching 3rd-year MBBS (Tribhuvan University, Nepal). Create a comprehensive, exam-oriented master table on Toxicology that is detailed enough to replace textbook notes while remaining easy to revise. For every poison or toxicological topic, present the information in a table with the following columns: | Topic/Poison | Definition & Source | Active Principle | Mechanism of Action | Fatal Dose | Fatal Period | Clinical Features | Diagnosis | Treatment & Antidote | Autopsy Findings | Specimens/Viscera Preserved | Medicolegal Importance | High-Yield TU Viva Points | Mnemonics/Memory Tips | Cover, at minimum: General toxicology (definitions, toxicokinetics, toxicodynamics, classification, routes, factors affecting toxicity) Principles of poisoning management (ABCDE, decontamination, gastric lavage, activated charcoal, enhanced elimination, antidotes) Corrosives and irritants Organophosphorus, carbamates, organochlorines Aluminium phosphide, zinc phosphide Heavy metals (arsenic, lead, mercury, copper, iron, thallium) Alcohols (ethanol, methanol, ethylene glycol) Gaseous poisons (carbon monoxide, cyanide, hydrogen sulphide) Narcotics and drugs of abuse (opium, morphine, heroin, cannabis, cocaine, amphetamines, barbiturates, benzodiazepines) Plant poisons (datura, aconite, nux vomica, oleander, abrus, castor) Animal poisons (snakebite, scorpion sting, bee sting) Food poisoning, mushroom poisoning Common drug poisonings (paracetamol, salicylates) Finally, include separate comparison tables for commonly confused topics such as: Organophosphorus vs Carbamate Methanol vs Ethanol Carbon monoxide vs Cyanide Arsenic vs Cholera Corrosive acid vs Alkali Acute vs Chronic poisoning Addiction vs Dependence vs Tolerance Deliriant vs Hallucinogen Use clear markdown tables, concise but high-yield language, and bold the facts most frequently asked in TU MBBS theory, viva, and OSPE.
