But she is now back on her feet after trying a treatment called Bee Venom Therapy (BVT.

Experts believe the venom in the sting helps ease the pain of MS symptoms and also stimulates the body to fight back Sami says she was stung around 1,

Bee Venom Therapy, or Apitherapy, uses the stings of live bees to relieve symptoms of MS such as pain, loss of coordination,

Researchers suggest that certain compounds in bee venom reduce inflammation and pain and a combination of all its ingredients helps the body to release natural healing compounds.

#Explosives and Pesticides Can Be detected by Using Bee Venom MIT scientists discover that bee venom can detect explosives and some pesticides.

Scientists from MIT have discovered that by coating carbon nanotubes in bee venom, they can create ultra-sensitive detectors for explosives such as TNT,

and fellow chemical engineers coated one-atom-thick tubes of carbon with protein fragments found in bee venom,

Its certainly an interesting use of venom especially after we recently saw that scorpion venom can be used to create pesticides.

Strano has filed for a patent on the sensor, and the team is still working out a compression system to ensure that any molecules in the air come into contact with the tubes

This is certainly a novel approach for using the proteins found in bee venom. It seems there are a number of potential uses for the poison,

#7 Science Careers You Never Knew Existed Snake venom handler? Sex scholar? A career in science doesn't have to mean a job in a dank lab or cubicle.

Snake milkers are animal care specialists who extract the venom of poisonous snakes. Snake venom while not exactly milk is nevertheless a life-giving substance (when used correctly.

The venom deadly on its own is the main ingredient in snakebite antidotes and a wide range of medicines.

Snake milkers have the job of extracting or milking the toxic substance from a snake's fangs.

The venom can be made into a freeze-dried powder that research laboratories use to produce drugs for blood clots heart attacks and high blood pressure.

#Sipping Tarantula Venom Kills Crop-Eating Insects The venom in a tarantula's fangs packs a lethal punch

But the toxic brew could also serve as an insecticide against agricultural pests that consume the venom orally a new study finds.

A component of the spider venom is especially effective against the cotton bollworm a pest that attacks crop plants.

In the last decade researchers have been investigating bioinsecticides proteins derived from natural sources such as spider venom.

The World's Creepiest Spiders In the study researchers milked venom from Australian tarantulas (Selenotypus plumipes)

A combination of the venom peptide and synthetic insecticide was even more effective. The venom was more potent against cotton bollworms than against termites and mealworms

which eat stored grains rather than crops results showed. Venoms from other insect-eating animals such as centipedes and scorpions may also contain peptides that could be used as bioinsecticides.

Or scientists could genetically engineer insect-resistant plants or microbes that produce these toxins. The breakthrough discovery that spider toxins can have oral activity has implications not only for their use as bioinsecticides

but also for spider-venom peptides that are being considered for therapeutic use study researcher Glenn King of the Institute for Molecular Bioscience at the University of Queensland Australiaâ said in a statement.

Males have a spur on the back of their hind feet that is connected to a venom-secreting gland.

More venom is secreted during mating season leading researchers to think that the spurs and venom help males compete for mates according to the Australian Platypus Conservatory.

The venom is not life threatening to humans but it can cause severe swelling and excruciating pain.

A typical platypus is 15 inches (38 centimeters from its head to the end of its rump.

Many species have potent neurotoxic venom which attacks the nervous system of the prey leading to respiratory paralysis if untreated.

Some cobras including all spitting cobras have cytotoxic venom that attacks body tissue and causes severe pain swelling and possible necrosis (death of cells and tissue).

Spitting cobras also have the ability to shoot venom from their fangs directly into the eyes of the victim with terrifying accuracy.

Venom in the eyes can lead to blindness if not washed out well. These 18-footers are the longest of all venomous snakes.

Though there are other snakes with more potent venom the amount of neurotoxin that a king cobra can emit in one bite is enough to kill 20 people or one elephant.

Their venom is potentially lethal and though antivenom exists it is not widely available in the black mamba s native habitat of southern and eastern Africa.

Mambas are slender agile and active with smooth scales and powerful venom. They all live throughout Sub-saharan africa.

Just two drops of potent black mamba venom can kill a human. Black mambas have a neurotoxic venom

which shuts down the nervous system and paralyzes victims. Without antivenom the fatality rate from a black mamba bite is 100 percent.

but the 1000 stings suffered by the man in Wichita Falls did not deliver a lethal dose of venom given his body weight.

With honeybees in particular the venom isn't really designed to kill. It's designed to educate basically to drive away an enemy

These include the general health of the victims and their weight and sensitivity to bee venom.

and while she said that everyone is likely to experience some kind of allergic reaction to bee venom only some individuals experience anaphylactic shock.


ScienceDaily_2013 03972.txt

and discomfort but for those with a bee venom allergy the consequences can be devastating:

In a paper to be published online Oct 24 in Immunity the researchers show that mice injected with a small dose of bee venom were later resistant to a potentially lethal dose of the same venom.

The study builds on earlier work by the researchers characterizing the innate immune response to snake venom and honeybee venom.

Innate immune responses occur in subjects exposed to a foreign substance such as a pathogen or a toxic material like venom for the first time.

In a previous study the researchers found that mast cells produce enzymes that can detoxify components of snake venom

and that mast cells can also enhance innate resistance to honeybee venom. Such innate immune responses do not require prior immunization or the development of specific antibodies.

To find out whether adaptive immune responses could help mice resist bee venom Marichal and Starkl first injected mice with a low dose of venom equivalent to one or two stings.

The mice developed more venom-specific immune cells and higher levels of Ige antibodies against the venom than control mice injected with a salt solution.

Three weeks later they injected both groups of mice with a potentially lethal dose of venom similar to five bee stings.

The immunized mice had less hypothermia and were three times more likely to survive than the control mice.

Moreover they did not develop the anaphylactic reactions characteristic of severe allergies. To determine whether Ige antibodies were required for this protection the team tested mice with three types of mutations:

In all three groups of mutant mice pre-immunization with a low dose of bee venom did not confer protection against a lethal dose suggesting that the protection depends on Ige signaling and mast cell activation.

Pre-immunization with a low dose of venom from the Russell's viper also protected mice from a higher dose of venom from this snake which is one of the big four species responsible for most snakebite

So the researchers believe the response could be generalized to different types of toxic venoms. Our findings support the hypothesis that this kind of venom-specific Ige-associated adaptive immune response developed at least in evolutionary terms to protect the host against potentially toxic amounts of venom such as would happen

if the animal encountered a whole nest of bees or in the event of a snakebite said Stephen Galli MD professor and chair of pathology and the co-senior author of the study.

or reptile venom but it would be unthinkable to test lethal doses of venom in humans.

Reptile and arthropod venoms are complex chemical cocktails. Some venom components have evolved to mimic chemicals made by the human body such as endothelin-1

which causes blood vessels to constrict during bacterial infections. At the same time mammals have evolved immune responses to venom which in some cases escalate into maladaptive allergic reactions.

We experience allergies in a much cleaner world where we don't have the same threats of venomous creatures

This is the first evidence that we know of indicating that Ige-associated'allergic-type'immune responses can actually reduce the toxicity of naturally occurring venoms.

#Australian tarantula venom contains novel insecticide against agricultural pestsspider venoms are usually toxic when injected into prey

but a new protein discovered in the venom of Australian tarantulas can also kill prey insects that consume the venom orally.

Isolated peptides from the venom of spiders or other venomous insectivorous animals such as centipedes and scorpions may have the potential to serve as bioinsecticides.
