Forensic scientists are able to use ink chromatography to solve crimes by matching documents or stains found at a crime scene to the marker or pen that belongs to a suspect. Forensic scientists analyze the unknown ink and compare it to writing utensils collected from possible suspects.
Symptoms of Variegate Porphyria The hepatic porphyrias primarily affect the nervous system, resulting in abdominal pain, vomiting, acute neuropathy, seizures, and mental disturbances, including hallucinations, depression, anxiety, and paranoia.
Background. The porphyrias are caused by enzyme deficiencies in the heme production pathway. Such deficiencies may be due to inborn errors of metabolism or exposure to environmental toxins or infectious agents. Because of the ubiquitous use of heme in the human body, severe enzyme deficiencies are lethal.
