Introduction to vampire porphyria
Porphyria has many manifestations, one of the most common is acute intermittent porphyria (AIP), one of the victims of which is King George III of Britain.
The most serious porphyria is congenital erythropoietic porphyria (CEP), whose tragic fate is suspected to be the origin of the vampire story. Although porphyria is usually caused by gene mutation, excessive drinking and environmental pollution can also cause the disease. The most notorious case occurred in Turkey in the 1950s. About 4000 people developed a type of porphyria after eating wheat sprayed with the fungicide hexachlorobenzene, killing hundreds. Shortly after that, HCB fungicides were banned worldwide.
Does porphyria need to drink blood? Early porphyria patients will indeed be advised by doctors to drink blood, because the heme in the blood will make the disease relieved and produce certain psychological comfort to the patients.
But more blood transfusions.
Symptoms of porphyria drinking blood
For most porphyria patients, blood transfusion and heme can effectively relieve symptoms, and it is still the mainstream treatment.
Heme is very tenacious and can still be absorbed by the small intestine through the digestive tract. This means, at least in theory, that ancient porphyria sufferers can make themselves feel better by drinking or drinking blood - probably the origin of the vampire story.
Fear of sunlight
Porphyrin is a kind of photosensitive pigment, which can gather on human skin, bones and teeth. Most porphyrins are benign in the dark and will not cause any harm to the body. However, once exposed to the sun, they will turn into dangerous toxins and devour human muscles and tissues.
Therefore, porphyria patients, like the legendary vampire, can only live in the dark world, can not see light.
Hate garlic
In the movie "blade fighter", the "blade" is invincible in dealing with vampires with garlic stained bullets and blades.
In most vampire legends, garlic, like the cross, is portrayed as the nemesis of vampires. Interestingly, people with porphyria also hate garlic. For a simple reason, some of the chemicals in garlic can worsen their condition, causing pain and other symptoms
Pale face
The vast majority of porphyria patients are accompanied by severe anemia, which is not only because they usually can only live in the dark, more importantly, porphyrins in their bodies will affect the hematopoietic function and destroy the production of heme. Usually, porphyria patients also have large areas of pigment deposition on their bodies - often purple.
Sharp teeth
For example, wolf: porphyrin will turn into a toxin that can devour muscles and tissues when exposed to sunlight. One of the main manifestations is that it will corrode the lips and gums of patients, exposing them to sharp, wolf like teeth. Rotten gums always look bloody, which inevitably reminds people of vampires who suck blood.
Eternal Life
As a result of the action of toxin, the ear and nose of porphyria patient will be corroded by it, and the skin will also be covered with scars, making them look very old.
In European legends, immortality is often described as a similar appearance. To spread false information, there is the saying that "vampires have immortality". In fact, the life span of porphyria patients is usually very short.
