Vampires and Biochemistry

Perhaps you are a fan of Twilight the movie or the Twilight series by Stephenie Meyer, or True Blood the television drama series created and produced by Alan Ball, based on The Southern Vampire Mysteries series of novels by Charlaine Harris. Vampires with their frightening appearance and unusual powers and weaknesses can cause one to pause and question how this is possible. Can this mythicalogical being brought to life in Dracula, the 1897 novel by Irish author Bram Stoker, featuring as its primary antagonist the vampire Count Dracula, have any basis in reality? Is there any connection to what we know about biological systems that could explain vampirism? I doubt that you would be surprised if I said yes, since this is a biochemistry course website.


Scientific Reasons to Believe in Vampires, Werewolves & Zombies

Let's take a look at some of the real-world events and phenomena that may have inspired the creation of vampires, werewolves and zombies.

Vampires in Myth and History

Vampire myths go back thousands of years and occur in almost every culture around the world. Their variety is almost endless; from red eyed monsters with green or pink hair in China to the Greek Lamia which has the upper body of a woman and the lower body of a winged serpent; from vampire foxes in Japan to a head with trailing entrails known as the Penanggalang in Malaysia.

However, the vampires we are familiar with today, although mutated by fiction and film, are largely based on Eastern European myths. The vampire myths of Europe originated in the far East, and were transported from places like China, Tibet and India with the trade caravans along the silk route to the Mediterranean. Here they spread out along the Black Sea coast to Greece, the Balkans and of course the Carpathian mountains, including Hungary and Transylvania.


The Legend of the Werewolf

Are they myth, magic or a medical condition?

Werewolves, beings that looked human and could turn themselves into wolves when ever they wanted to, apart from on a full moon, when they could not stop themselves, and they transformed whether they wanted to or not. Some of them were said to turn into a creature that was half wolf, half man, while other were said to turn into wolf completely.


Werewolves - A Medical Perspective

The werewolf has played an important part in universal folklore since pre-Christian times. A werewolf is classically defined as "a person that shape shifts into a wolf without losing the capacity to think as a human." Science has attempted to explain the rationale behind the myth by highlighting a number of diseases that have over the centuries contributed to the werewolf legend:


Rabies and Lycanthropy

A rabid canine, according to clinical observations, becomes "increasingly irritable, restless, and nervous.... It shows exaggerated response to sudden stimuli of sight and sound. Excitability, photophobia, and hyperesthesia may become apparent...the animal may begin to move and roam, and wander aimlessly, all the time becoming more irritable and vicious; at this stage the animal is now very dangerous because of its tendency to bite anything that it encounters, be it man, animal, or inanimate objects. If the animal is confined it will bite at chains or bars of the cage or kennel, breaking its teeth, and inflicting severe trauma on its oral tissues.


Vampires: Eternal Bloodlust

Everybody knows vampires, those immortal creatures that drink the blood of their victims. Hollywood is especially fond of them -- there are probably as many vampire pictures as there are gangster movies. In fact, it's mostly through this medium that they've gained their popularity.

With the new vampire flick Eternal coming out soon, interest in the genre is expected to shoot up again. Let's get prepped by exploring the mythical world of vampires from a scientific, historical and sociological standpoint.

Some info:

Let's start with what most of us know of the vampire myth.

Vampire Physiology

Blood

Blood has been a symbol of life since very ancient times. The blood in our veins has always been iconic of our continuing life. To lose too much blood is to lose consciousness, breath, and eventually, our very lives. If a person or animal is already dead and is cut open, blood does not flow. Only the living have blood that flows. Blood has been used throughout the ages as a ceremonial sacrifice. In pagan times our forefathers worshipped their gods with blood sacrifice. And today, indeed, we are not so different. Even in modern times, in our churches, there are those taking communion or the Eucharist, and drinking of the wine that symbolizes Christ's blood.

It seems appropriate, then, that this creature who is an antithesis of both death and life should gain his strength from feeding from the life's blood of humans. For the vampire, the drinking of blood is its life, its sustenance, and the single thing that makes it identifiable all around the world, regardless of the culture in which you were raised or the language you speak.

The Werewolf Syndrome: Compulsive Bestial Slaughterers

Attack

In 1995, a young woman in Douglas County, Washington, was unable to get her mother or fourteen-year-old sister, Amanda, to answer the phone. That was unusual, so she went to check on them. The front door was locked, so she went around to a sliding rear door that was always unlocked. Inside the home, she found their bodies. One was in a bedroom and one in the family room, both smeared in a great deal of blood. She ran to a neighbor, who called for help. The responding police officers observed that the victims of this grotesque double homicide had been sexually mutilated in a variety of ways by someone who seemed more animal than human.


The History of Vampires

I. It Started With Blood

The Vampire persona has evolved from many true and untrue facts, legends and myths. At various times vampires, real and imagined, have been considered fiends, supernatural beings, shape-shifters, mentally disturbed deviants, satanic servants and fetish followers. However, it all began and still revolves around a taste for blood!

Contrary to the popular belief that Vampire history, stories and legends began with Vlad the Impaler, they go back much further than that. Many ancient societies worshipped blood thirty gods. This caused people to begin to associate blood with divinity, leading to the development of the early vampire cults. Regardless of the spiritual value, some people have always had a desire to drink blood and the reasons are as varied as the practitioners. In some societies the practice was accepted, as in ancient Egypt. But in others, vampirism was considered deviant behavior and condemned.
