  • Body snatchers: grave robbing for medicine

    NOTE: This post is not related in any way to the 1956 sci-fi film that depicts an extraterrestrial invasion where the invaders “steal” human bodies. This is NOT a review of the Invasion of the Body Snatchers (though I do highly recommend the film).

    Rather, this is brief overview of a period when robbing bodies, often from graves, was used as a means to provide physicians with subjects for dissections.

    When?

    Body snatching was most prevalent during the seventeenth to nineteenth century, though there have been reports of this activity occurring as early as the fourteenth century.

    Why body snatching?

    – Surgical practice (High Demand): Most fifteenth century physicians scorned and considered it degrading to work with their hands; They often stood by patients they treated and ordered servants to perform what they thought should be done by hand. This disconnect between the physician and surgery created a void in anatomical and surgical knowledge. During the sixteenth century, Andreas Vesalius, a Flemish physician, led a movement to fill that gap. His efforts culminated in the publication of De humani corporis fabrica, one of the greatest anatomical textbooks. During that time, Vesalius traveled around Europe performing dissections himself, generating interest in surgery and leading physicians to embrace the values of a hands-on approach to medicine. This surge in interest in surgical practice created a great demand for bodies to be used for dissection.

    – Shortage of bodies (low supply): Two centuries ago most states did not permit the use of unclaimed bodies for dissections and most of the states that did limited them to executed criminals. However, this was not enough as executions were few in the states. For example, Massachusetts executed less than 40 persons from 1800-1830. In addition, as the number of medical schools increased, so did the demand for bodies. This legal blockade created a shortage of bodies available for medical schools forcing them to turn elsewhere.

    –Body decay (high turnover): Lack of refrigeration was a common problem back then; not only did it spoil food, but it spoiled bodies. This meant that there was a high turnover rate; physicians had a limited time frame to dissect and study bodies after death. This created a situation where there was a constant demand for bodies.

    SOLUTION: Where can you find a large supply of bodies? Graveyards.

    Who stole bodies?

    -At first, grave robbers were medical professionals, students, and hospital porters who stole bodies for their own purposes. However, as time passed, medical schools advised students, faculty, and personnel to avoid engaging directly in stealing bodies. From there grew a class of individuals known as resurrectionists or body snatchers, men who made a living exhuming corpses and selling them to schools. Eventually, body snatching organizations/gangs started to appear. As laws were put in place, robbing became more profitable; their task became increasingly difficult and dangerous, and the price of their commodity increased.

    -Since body snatching was an arduous task, it was often men who participated in this activity, though women were sometimes involved in non-physical tasks or snatching bodies not yet buried (falsely claiming a body to be buried).

    Whose body was stolen?

    -Race, sex, and social status did not matter. Nobody was safe from disinterment.

    Note: Though records show that people of all race, gender, and social status were victims, the golden era of body snatching coincided with the period of racial and social inequality in the states. This meant that immigrants, blacks, and the poor were most often targeted.

    The Art of Body Snatching:

    Many considered body snatching an art. Some texts describe the act in lengthy detail spanning several pages, detailing tactics on how to procure bodies as efficiently as possible. I will spare you from the lengthy details without skipping over the essential techniques.

    Step 1: Secure knowledge of a prospective burial: Information of a burial was usually supplied by mail or messenger. Such a message was often sent in code and not directly to the resurrectionists, but through some intermediary, such as a druggist.

    Step 2: Scope the location: The grave should be accurately located during daylight hours so that a search in the dark would be unnecessary. A common method was to reconnoiter as a hunter. A stranger would appear in the neighborhood on the day of burial with a shotgun over his shoulder, apparently hunting small game.

    Step 3: Wait until nighttime

    Step 4: Begin the disinterment

    • Plan: At least two men and a watcher/driver were needed in a disinterment. One man remained with the transport; that person would drop off the other three at the location and return at a specified time. The other two removed the body.
    • Execute: The process of disinterment was fairly straightforward:  a hole would be dug directly above the coffin, the coffin would be opened, and finally, the body would be pulled out. Since graves were dug to be about 5 ft deep (from the top of the coffin), extracting a body could be quite laborious. To make the extraction easier, resurrectionists used a modified pole to drag bodies out of graves. This pole was hooked at one end and had grips at the other (similar to the letter ‘J’). The hook would be placed under the chin of the deceased and the men would push or pull the body out using the other end of the pole. As you can imagine, this ‘hooking’ technique often caused damage to the corpse.

    Step 5: Clean Up: The grave should look as it did before the disinterment to avoid suspicion and capture.

     

    Ethics

    The seventeenth to nineteenth century was a great era for medicine. Discoveries in anatomy led to improved surgical treatments and healthcare. However, people often forget that many of these advancements came at the expense of bodies being robbed. Families would go to cemeteries to pay respects for loved ones only to find the grave(s) in disarray, or would pay respects without knowing the remains of their loved were gone. Until the adoption of more coherent and stricter laws regarding body donation, many physicians considered body snatching a necessary evil.

  • Ultraviolet radiation: what you can’t see can still hurt you

    A few weeks ago, a friend of mine showed me an article on MSN about a man whose face was obviously more wrinkled on one side than the other. Mr. McElligott, the gentleman featured in the article, drove a delivery truck for 28 years, exposing the left side of his face to the sun for several hours each day. I have heard several times throughout the years about the importance of sun protection, but hadn’t ever dwelled on the topic for much time. Once I read about Mr. McElligott, though, I was quite intrigued and started thinking about the whys and hows of sun damage, UV radiation, and wrinkles.

    In the pictures above, you can see Mr. McElligott’s original picture in the middle with an altered image on either side. I transposed one side of his face to that of the same side in an attempt to make the difference between the two sides of his face more apparent.

    Here you can find an “up-close and personal” version of the center picture. (How cool are his eyes?!?)

    As you may already know, skin is made up of three major layers: the epidermis, dermis, and subcutis (also known as the subcutaneous layer or the hypodermis). As in the diagram below, the epidermis is on top, then the dermis, and lastly the hypodermis. Freckles and moles, as well as sunburns, appear in the epidermis. The dermis houses the structural elements in skin which keep it firm and elastic. This is the section of skin where wrinkles form.

    Sunlight is known to negatively affect skin. This is because UV radiation (part of sunlight) can suppress the immune system, damage DNA, and alter skin texture, blood vessels and skin pigment. While conditions like thin skin and easy bruising are usually associated with old age, they are often lasting effects from UV damage as the majority of skin damage comes from the sun and not from Father Time.

    The Sun emits three types of ultraviolet radiation: UVA, UVB, and UVC, with wavelengths of ~315 to 400 nm,  ~290 to 315 nm, and ~100 to 290 nm, respectively. UVC radiation is absorbed by the ozone layer and doesn’t reach ground level. UVB radiation makes its way through the ozone layer and is the type of UV that hits the epidermal layer of skin and causes sunburns or tans; it is also known to cause skin cancer. Unlike UVA radiation which is relatively constant all year long, UVB radiation is stronger during the summer months. UVA is unique in its ability to pass through glass. Thinking back to Mr. McElligott, UVA radiation’s ability to penetrate glass led him to have a build up of UVA damage of the course of his career. Even on days when he drove with his window up, he would have been protected from UVB rays, perhaps not getting a sunburn or tan, but would have still received the negative effects of UVA. UVA rays cause damage to the dermis, destroying elasticity and potentially causing mutations in DNA. Out of all of the UV radiation that reaches us from the Sun, there is over 20 times more UVA than UVB.

    Harm to the skin caused by the Sun’s UV radiation is often referred to as photoaging, or dermatoheliosis. Photoaging is caused when UVA and UVB rays enter the skin, negatively affecting two of skin’s structural proteins, elastin and collagen. Radiation damages elastin and causes a build-up of altered metalloproteinase enzyme. Normally, metalloproteinases (also known as collagenases) help reverse skin damage by creating new collagen. Unfortunately, the metalloproteinase from the damaged elastin does the exact opposite— it breaks down collagen, leaving the skin with a broken collagen structure and wrinkles. (For a study on the effects of metalloproteinase,  check out this article.)

    Exposure to UV radiation in sunlight, in addition to air pollution and smoking/second-hand smoke, can also subject the skin to free radicals. Free radicals are molecules (or atoms) with a single, unpaired electron. Because a free radical lacks the second electron, it is unstable and thus seeks out another electron. When it reaches another molecule, the free radical takes an electron, completing its electron pair while leaving the second molecule with an unpaired electron (a new radical). This snowball effect continues throughout the skin, activating altered metalloproteinase and causing damage to collagen.

    Jeanne (left) and Susan (right), identical twin sisters, serve as a great example of how lifestyle choices can determine a person's skin aging. As children, the two women had an uncanny resemblance, but now it's easy to see that Susan's decision to sunbathe and smoke led her skin to age more rapidly.

    Well, I hope you enjoyed learning more about wrinkles and UV radiation! Remember, prevention is key! Make sure to slather up in some good ol’ broad spectrum SPF 70 next time you go shoot some hoops (or do whatever it is that you do) and enjoy this fine video about why we need the Sun (even though it hurts us sometimes):
