Animals that bring health to humans

Not all creatures on earth we can love right away, especially those animals that have just seen 'sneaky'. For example, many of us are afraid of spiders, spiders are in the Top 10 obsessed species of the world. But hidden outside their ugly, disgusting forms are the elixir of medicine to heal many diseases for humans.

Mary Astell, a 17th-century British philosopher once said: 'No creature of God is purely contemptuous; the most miserable insects are also effective and virtuous' . It sounds true especially to the medical world. House flies eat garbage and feces and carry more than 100 dangerous threatening pathogens that can be transmitted to humans. But you will be surprised to learn that the house fly has helped scientists find the cause of disease in humans.

In a study published in the Journal of Genetic Biology in October 2014, Dr. Jeff Scott and colleagues from Cornell University in Ithaca (New York, USA) revealed the genome decoding of House flies using DNA from 6 female flies. Comparing the fly's DNA with fruit flies - which have 60% of human genes - the team determined that the genes made the flies immune to the agents they carried, meaning we would also have New treatment for humanity. And this discovery is just the tip of the iceberg, there are many other medicinal herbs from other creatures that give people.

Spider: Relieves pain and damages nerve damage

Many new people think of the word "spider" that feels frightened. Millions of people around the world hate 8-foot creatures often living below the sofa. But the truth is, spiders are great creatures. It is estimated that at least 40,000 species of spiders are living all over the world, on every continent except Antarctica. Although all spiders are biting, only about a dozen of them can be harmful to humans with extremely poisonous venom.

The black widow spider, reclusive brown spider and Hobo spider are some of the venomous spiders found in the United States. Just one bite of one of the three spiders also causes symptoms such as fever, itching or rash, vomiting, high blood pressure and difficulty breathing. Rarely, spider bites can cause death. Although venom is harmful to people, it also has benefits for human health.

Black widow spider's venom can be a pain reliever.

In early April 2015, Today's Medical News Newspaper (MNT) reported on a study conducted by researchers at the University of Queensland (Australia), who claimed that several studies were identified. substances in spider venom can cure chronic pain in humans. By examining the venom of 205 species of spiders, the researchers discovered that 40% of venom contains at least 1 compound that is able to block chronic pain in humans, they call the compound Nav1. .7. There is a special compound called Hd1a found in a spider named Haplopelma doriae - a member of the wolf spider family, showing great promise.

Lead researcher Professor Glenn King believes new discoveries can lead to more effective treatments for millions of people around the world - people with chronic pain.GS Glenn King added: 'Declaration The natural source of new drugs has brought a special hope for the development of a new generation of painkillers, which can help people with chronic pain have not been healed. from current treatments'. And it is not only spider venom that can create new drugs for humans. Spider silk - a type of protein that this creature uses to make spider webs - is also useful in treating nerve damage in humans, according to a study conducted in 2011 by researchers. from the Hannover medical school (Germany).

Spider silk is very strong, the study claims that it is five times stronger than steel. Hannover researchers believe that because of the high strength of spider silk, it could be a good candidate for neurosurgery, this technique has been proven successful in animal bodies.

Bees: Helps fight against antibiotic resistance and HIV treatment

Bee venom is also very terrible, but they are responsible for producing one of the world's most beloved foods: honey. And according to scientists, this creature has even more benefits. In 2013, MNT newspaper reported on a study published in the Antiviral Therapy, in which scientists discovered how a poison found in bee venom - melittin - re has the potential to destroy human immunodeficiency virus (HIV). Investigators came from the University of Washington medical school, explaining that melittin could create holes in a protective, double-layer membrane around the HIV virus. Increasing the dose of toxic melittin injecting into the HIV virus through nanoparticles can be an optimal way to kill HIV.

The substance contained in bee venom can kill the HIV virus.

Research author Dr. Joshua L. Hood believes that these new discoveries could lead to the creation of a vaginal gel to stop the spread of HIV. Dr. Hood explained: 'We hope that in places where the density of HIV is rapidly spread, people can use this topical gel as a precautionary measure to prevent initial infection'. A study published in September 2014 stated that bees also proved useful in creating a new generation of antibiotics. Researchers at Lund University (Sweden) discovered a lactic acid bacterium in the bee's stomach that has antibacterial properties. The team found that bacteria proved effective against a large number of drug-resistant agents responsible for potentially life-threatening infections, including resistance to methicillinStaphylococcus aureus (MRSA) and vancomycin resistance. Enterococcus (VRE) . The researchers say their findings have shown a viable alternative.

Scorpion: Treating cardiovascular problems

Like spiders, scorpions are fierce but mesmerizing. There are about 90 species of scorpions living in the US, most of them live in mountain rocks and sandbanks. All scorpions have venom, but only 25-30 venom scorpions are enough to cause dangerous diseases for humans. If a person is bitten by venomous scorpions, symptoms such as dyspnea, muscle spasms, high blood pressure, increased or decreased heart rate and abnormal heart beats will appear. But miraculously, the venom of the scorpion has both rescued and saved the lives of cardiovascular patients.

A study in 2011 by researchers at the University of Wisconsin-Madison School of Medicine and Community Health discovered that compounds are found in the venom of the African Emperor's scorpion (Pandinus imperator). , proved effective in treating heart failure. The researchers found compounds called calcin that can release calcium in human heart cells, allowing the heart to contract better - sometimes limiting people with heart failure.

The venom of the scorpion African Emperor (Pandinus imperator) is able to cure heart failure in humans.

Another study published in 2010 identified a compound found in the venom of the Central American bark scorpion - a kind of scorpion raised as a pet - that could prevent cardiac arrest when it falls. Researchers from the University of Leeds (UK) have explained that the compound called Margatoxin , can prevent neointimal hyperplasia after heart surgery - a common complication that often causes blood vessel blockage. . Margatoxin works by blocking a potassium ion channel called Kv1.3, including neointimal hyperplasia. Professor Peter Weissberg, medical director at the British Heart Foundation (BHF), said: 'The results are generally very promising, but we are not sure whether this approach will benefit patients in surgery for until more research is needed on patients, aiming to establish long-term and safe efficacy. Scorpion venom has many potential medical benefits if used appropriately. '

Frog: Help with the fight against cancer

Frogs are probably one of the least fearful animals, and one of the most interesting species for the medical world. It is capable of jumping up to 20 times more than body length, and some frogs like Budgett frogs also have the ability to camouflage intellectually. There are more than 6,000 frog species living around the world, of which 90 are living in the US. Only a few frogs have venom harmful to humans. Indeed, some frogs benefit humans in the fight against cancer. In 2011, MNT reported a study conducted by researchers at Queen's Belfast University (Northern Ireland) revealing that there are two proteins in the skin of the waxed Monkey frog and the toad giant Firebellied. may disrupt vascular formation, or new vascular growth.

The venom of the wax monkey frog can disrupt vascular formation, or new vascular growth in anti-cancer.

Researchers explain that cancer tumors grow in their blood supply, they feed oxygen and nutrients to grow. A protein that will turn off vascular growth means that tumors will not load enough fuel for themselves, meaning they will stop growing. Head of research author Chris Shaw explains: 'Stopping blood vessels from developing them will lead to less spread of tumors and eventually they are destroyed. This is the potential to reform the cancer from 'death station' to chronic disease. ' On the other hand, Professor Shaw says such a protein can trigger blood vessel growth, helping to repair blood vessels quickly when they are damaged after a stroke.

Reptile: Managing and treating diabetes

Have you ever heard of the name of the monster Gila. Found in the Southwestern United States and Northwest Mexico, this is a venomous lizard, and is a very small number of venomous lizards in the world. A bite of this lizard is not fatal for adults but its saliva is also a lifesaver.

In 2007, a study by researchers at Chapel Hill School of Medicine at the University of North Carolina (USA) discovered how exenatide - a synthetic compound found in the saliva of a monster Gila animals, also known as Exendin-4 - may help control diabetes conditions and cause weight loss. This compound works by having the pancreas produce more insulin when blood sugar is too high. In that study, 46% of patients - who received exenatide doses with a combination of Metformin diabetes medications, and controlled their blood sugar well, compared to only 13% of those taking control. .

Gila saliva can help treat diabetes.

Dr. Michael Trautmann from the pharmaceutical company Eli Lilly, who helped develop the new drug, explains: 'Gila children eat only 3-4 times a year, and its salivary glands produce a compound called exendin-4 can help them digest meals for a very long time. This is very important in controlling diabetes'. Further, not only Gila can treat diabetes. A 2012 study published in Nature has discovered that there are poisons in a snake venom that can also help heal high blood pressure and cancer.

The team analyzed the sequences of Burmese pythons to find important discoveries. They discovered that, although the snakes of these snakes can be harmful to humans, they can be converted into less toxic molecules to make specific drugs. Lead researcher Dr. Nicholas Casewell from Liverpool College of Tropical Medicine (UK) explains: 'The venom of snakes has been involved in new functions for molecules, some of the venom can kill. prey, while others form new functions in other tissues of the body.
