Drugs from Spider's Venom

The venom of a particular species of spider can act like natural viagra. According to a recent report published in Live Science, a person stung by this Brazilian wandering spider Phoneutria nigriventer not only experiences extreme pain but also an increase in blood pressure resulting in enhanced sexual stimulate in. Said the study research team member Romulo Leite of the Medical College of Georgia: "We are hoping that this will eventually end up the development of real drugs for the treatment of erectile dysfuction." A study by resarchers at Johns Hopkins University found that about 18 million men in the US suffer from erectile dysfunction. Worldwide, the number of such males may be quite large.
Kenia Pedrosa Nunes of the Medical College of Georgia, another member of the study team, separated different components of the spider venom and ran tests on rats to seek out the erectile enhancer. Finally he could identify the desired compound. Dubbed TX2.6, the compound turned out to be a relatively short string of amino acids called a peptide. When injected with the peptide, the rats showed enhanced sexual stimulation. It is interesting to note that the Brazilian wandering spiders instead of making nets hide themselves in clothes, shoes and crevices or cracks of furniture etc. kept in a household. When a person tries enhanced a person tries to kill or scare them or accidentally presses them with hands or legs they get infuriated and bite.
In South America too a giant spider, called wolf spider's venom is very deadly. Britten by this spider one might even die. Another spider, named black window, has a shiny black coat on its body and is found in most parts of North America. It is also highly venomous.
It maybe pointed out that in the past too some experiments with spider venom on rats proved to be successful. This has raised the hopes of using spiders' venom for the development of new drugs. It might sound surprising but he spider's venom is even costlier than the snake's venom. In Russia, 1 gram of spider's venom costs between 20 and 30 thousand Roubles; and the venom of some 8000 spiders is required to get 1 gram of the poison. According to scientists, it will be possible in future to develop many useful drugs, vaccines etc. from the spiders' venom
