Dolphins offer clues for wound healing
US: “Much about the dolphin’s healing process remains unreported and
poorly documented,” wrote Michael Zasloff, adjunct professor at
Georgetown University Medical Center who interviewed dolphin handlers
and marine biologists to find answers about the miraculous self-healing
power of the species.
In his letter published in the Journal of Investigative Dermatology,
Zasloff recounts several documentations about how quick dolphins manage
to heal the wounds caused by severe shark bites, adding that some of
these wounds which are larger than a basketball are cured in weeks
without causing notable pain or infection or leaving a significant scar.
“If I saw this in a human being, I wouldn’t believe it,” Zasloff
added. “It should awe us. You have an animal that has evolved in the
ocean without hands or legs, which swims faster than we can, has
intelligence that perhaps equals our social and emotional complexity,
and its healing is almost alien compared to what we are capable of.”
The investigator scientist concluded that dolphins’ resistance to
infection may be linked to their blubber that contains natural
organohalogen compounds, which function like antibiotics and have
antimicrobial properties.
“It’s most likely that the dolphin stores its own antimicrobial
compound and releases it when an injury occurs,” said Zasloff, who
previously identified antimicrobial compounds in frog skin and dogfish
sharks. “The repair of a gaping wound to an appearance that is near
normal requires the ability of the injured animal to knit newly formed
tissues with the existing fabric of adipocytes [fat cells], collagen and
elastic fibers,” Zasloff noted. “The dolphin’s healing is similar to how
mammalian fetuses are able to heal in the womb.”
In addition, dolphin’s unique diving mechanism that might stem in
their blood flow enhance healing by diverting blood from the extremities
while plunging below the sea, he suggested.
The reflex could be triggered after an injury to prevent excessive
blood loss.
“Unfortunately, the healing process of dolphins has been poorly
studied, but hopefully we’ll soon know more, and be able to apply some
of what we learn to helping humans,” he expressed.
“My hope is this work will stimulate research that will benefit
humans,” said Zasloff. “I feel reasonably certain that within this
animal’s healing wounds we will find novel antimicrobial agents as well
as potent. Press TV
