How One Snake's Venom Turns Your Blood To Jell-O And Reverses Puberty.
In the somewhat disturbing video below, a single drop of venom from a Russell's viper is enough to cause a cup of blood to coagulate into a gelatin-like slab of clotted matter:
If that wasn't enough to make you swear off YouTube forever, imagine that same process happening inside your own blood vessels
Russell's viper, or
, has a broad range throughout Southeast Asia and is one of the primary causes of snakebite in the region, according to Max Alan Nickerson, a herpetologist her·pe·tol·o·gy

It displays exhibits on the flora, fauna, and people of Florida. The main museum is free of charge (but requests a donation). .
The venom of the Russell's viper, like that of many snakes, is a complex combination of a variety of components that can either encourage or block blood coagulation. Procoagulating factors interact with naturally occurring clotting proteins in the blood and can cause a cascading reaction, resulting in blood clots in vessels that can affect various organs throughout the body, according to Nickerson.
The clotting properties of Russell's viper venom actually make it useful in (http://en.wikipedia.org/wiki/Dilute_Russell%27s_viper_venom_time) medical laboratory tests used to look for the presence of special anti-coagulating factors in a patient's blood.
Somewhere between 40 and 70 milligrams of Russell's viper venom is usually enough to kill a person. A single snake can carry up to more than 250 milligrams of venom, but not all snake bites deliver the same amount of poison.
"The amount of venom in a bite varies from none to nearly emptying the venom gland," Nickerson said in an email.
Russell's viper venom can also affect the pituitary gland pituitary gland, small oval endocrine gland that lies at the base of the brain. It is sometimes called the master gland of the body because all the other endocrine glands depend on its secretions for stimulation (see endocrine system). , the small pea-sized organ involved in hormone production. (http://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2887%2992500-1/abstract) A 1987 study of 24 people that had previously been bitten by the viper found that 7 had clinical features of hypopituitarism Hypopituitarism Definition
Hypopituitarism is loss of function in an endocrine gland due to failure of the pituitary gland to secrete hormones which stimulate that gland's function. The pituitary gland is located at the base of the brain. , which often results in the loss of secondary sex characteristics like curviness in women and facial hair on men.
"Russell's viper envenoming may thus produce a disorder resembling Sheehan's syndrome," a pituitary condition seen in pregnant women, the study's authors wrote in the Lancet.
If you are unlucky enough to be bitten by a Russell's viper, seek medical attention and (http://firstaid.webmd.com/snakebite-treatment) don't try to suck the venom out of the wound . Antivenom antivenom Antivenin Toxicology A vehicle that contains an antibody or other substance that binds specifically to a toxin, deactivating it , which is made by giving a diluted solution of snake venom to an animal and then collecting the antibodies produced in response, is your best chance to avoid lasting damage or death.
