Study Notes
Philippine Crime Laboratories
- Established in 1959, with Freer as the 1st director of the Philippine Constabulary Laboratory.
- Transitioned to PNP Crime Laboratory after the abolition of the Philippine Constabulary.
- Initially aimed to perform biological and chemical analyses, and produce vaccines and sera.
Historical Context of Forensic Toxicology
- In 1904, forensic analyses included counterfeit coin examination, poison tests, and bloodstain analysis.
- Department of Legal Medicine created on March 11, 1915, under Dr. Sixto de los Angeles.
Effects of Chronic Poisoning
- Larger doses may induce hallucinations, memory loss, anxiety, paranoia, and can lead to death.
- Common agents include cannabis, ketamine, LSD, psilocybin, and PCP.
Stimulants and Their Effects
- Stimulants enhance communication between brain and body, increasing heart rate and blood pressure.
Types of Poisoning
- Accidental: Poison ingested unintentionally.
- Homicidal: Administered with intent to kill.
- Suicidal: Victim ingests poison to end their life.
Blood Alcohol Concentration Effects
- Alcohol percentage affects clinical intoxication and varies in storage duration in biological samples.
- Blood: detectable for up to 2 days; Saliva: 2 days; Urine: up to 3 days.
Factors Affecting Drug Impact
- Key factors include weight, frequency of use, dosage, and the individual’s metabolism.
Poison Isolation and Examination Methods
- Isolation: Pure forms of poison isolated through extraction using solvents.
- Symptoms of acute poisoning arise suddenly, while chronic poisoning presents with gradual symptoms.
Concepts Related to Dosage
- Dose: Specific amount of a drug administered; critical for therapeutic vs. toxic effects.
- Toxic Dose (TD): Dose that produces toxicity in a percentage of the population; TD50 indicates toxicity for 50% of test animals.
Precipitating Agents and Chemical Antidotes
- Precipitating agents prevent poison absorption, while chemical antidotes render poisons harmless by altering their chemical structure.
Notable Poisons and Their Uses
- Strychnine: Derived from nux vomica, used as a rodenticide and stimulant.
- Nicotine: Active principle in tobacco, also an insecticide.
- Morphine: Opium derivative used for pain relief and sedation.
- Arsenic: Toxic element used in wood preservation and as an insecticide.
- Methyl Alcohol (Methanol): Flammable, poisonous alcohol employed as a solvent and antifreeze.
