10 amazing ways animals help us to treat diseases

Animals have always been a big part of medical research. They are most commonly used in clinical trials that test the efficacy and safety of new drugs before continuing with human trials. [1]

While animal testing is crucial to the success of medicinal products for human use, there are astounding lines of research with animals in a less traditional sense. In some cases, animals need to be trained to track down illnesses, use their body fluids to treat humans, or even use components of otherwise deadly poisons. Whether you are for or against animal testing, you will definitely blow the things out on this list!

10 Dogs Smell Cancer

There are many stories that tell how a pet owner noticed her dog behaving strangely around her. Open another exam, notice a lump, or feel sick. After they go to the doctors, they are diagnosed with cancer and their dogs have to thank for saving their lives! But how does science work around that?

You can only say one thing: the astonishing sense of smell of the dogs. In our nose we have olfactory receptors with which we can distinguish odors. The average person has about six million of them in the nose, while dogs have a whopping 300 million. This makes their sense of smell much more than superhuman; As a result, they can detect the slightest difference in the odors. Which scent does a dog take most often? Your owner of course. In view of this, it makes sense to believe that dogs can even smell biological changes in us.

How effective is this method of detecting cancer early? A study of urine from prostate cancer patients found that dogs had a 91 percent success rate in identifying the cancer. [2] Maybe someday, in the near future, we will see dogs as a cancer screening method.

9 Animals improve symptoms of mental illness

You have probably heard that animals have a positive effect on depression, but these are not the only mental illnesses that can improve animals. To list some, animals help with autism, ADHD and anxiety. [3]

Animals create this by offering social opportunities that would otherwise not arise. A good example of this is a depressed pet owner walking with his dog. Exercise of any kind has been proven time and again to relieve the symptoms of depression, as well as being outside of nature. Pets can help to improve sensory perception in autistic individuals, and people who suffer from ADHD can take a more routine view and handle the responsibility of caring for a living being.

Which pet owner does not feel better after being stroked and cuddled with cat, dog, horse, rabbit or any other pet? Knowing that an animal loves you unconditionally is a special feeling and can reduce the psychological burden of illnesses such as depression and anxiety disorders.

8 Zebrafish and metabolic disorders

In the United States, the vast majority of adults are either obese or overweight. In fact, 160 million people (including adults and children) are overweight or obese. In the body of an obese person, there is an underproduction or lack of sensitivity to leptin (a hormone that inhibits hunger and regulates fat stores) and a decrease in the body's sensitivity to insulin (which regulates fat, carbohydrate and protein metabolism) , Because of this, obesity is considered a metabolic disorder because hormones that regulate our metabolism are compromised.

Proteins found in zebrafish have been used in clinical studies in mice fed a high-fat diet. The use of these proteins as an active ingredient injection protected the mice from the causes of obesity, which were explained above as a lack of sensitivity for necessary metabolic hormones. [4] If this can be applied to humans, it means that a simple injection can mitigate most of the damage caused by our Westernized diets. The results are remarkable and have opened a large research field for the treatment of metabolic diseases.

7 Brazilian viper venom and high blood pressure

The poison of Bothrops jararaca of a Brazilian pit viper, can cause bleeding (if your blood does not clot) are bitten by it. [5] That sounds terrifying, and the snake looks pretty frightening too. So it is a great surprise that the poison of this deadly snake has led to the discovery of the method that addresses another of America's biggest health problems: hypertension.

If it is fatal to inject this poison into you, how could this possibly help us? The whole process is actually quite revolutionary. Previously, medical researchers were looking everywhere for the key to lowering blood pressure. The venom of the Brazilian viper gave us this key. ACE inhibitors, the current treatment for hypertension, were originally developed from a peptide in venom. These inhibitors block receptors in our body that cause our blood vessels to contract, resulting in high blood pressure.

6 Childhood blindness and mice

While blindness in children is not as common in this list as other diseases, it is still very unhappy. Children are born without one of their five main senses, which makes their lives difficult at an early age. Someone who was born blind to give the eyesight seems to be an impossible miracle, but a linked gene found in mice could make this possible.

A 2006 study looked at childhood blindness caused by defective genes. This means that the right cells that enable vision are not created. This model was restored in mice by switching off the same gene that is missing or damaged in blind people. Using gene transfer to reintroduce a healthy version of the same gene, the mice could begin to produce the cells necessary for vision. [6]

5 Giant Pandas Antibacterial Blood

Giant pandas look sweet and cuddly Their benefits to humans are much more than just a delightful appearance.

Pandas happen to pick up many bacteria in their natural habitat and encounter them. Due to their constant exposure, their bodies have evolved to produce several natural antibiotic strains. We can derive specific compounds from the genes of the pandas and make various antibiotics that fight bacteria and fungi.

This is significant as it has been found that antibiotic pandas kill certain bacterial strains six times faster than the antibiotics currently used. [7]

4 Cats' Purring Heals

This is pretty stunning. There are legitimate medical examinations that support the healing properties of a cat's purr. If there were not enough reasons to own a cat, aspiring cat owners should be marginalized.

There are some frequencies that promote bone growth and healing. They are 25 and 50 hertz. [8] These low frequencies are also in the cat's purr range, somewhere between 25 and 150 hertz. Scientists suspect that the reason for the cat's purring is to promote self-healing by using its own frequencies to help with internal bone injuries. This would also explain why cats purr when they are under stress or in pain.

The pressing question is whether it really benefits human bone as well. There is no scientific research directly supporting this theory, but many studies have shown that pet owners live longer. If the purring of cats has helped, that would be pretty amazing.

3 Dolphins could make us super healer

Imagine you would get a Haibiss and not suffer so much. Although shark bites are usually not fatal, we still have much to do to heal the wound properly. Stings, antibiotics and other measures must be taken to ensure that the wound closes and does not become infected.

Large injuries observed on dolphins (probably caused by sharks) do not require any special attention for healing. Her injuries healed in just a few weeks, though the wounds were severe. The dolphins showed no signs of intense pain or discomfort due to their injuries, and no lasting damage was done to them. [9]

This healing power is unknown in any human being suffering from an injury of this magnitude. So how do dolphins do it and how can that benefit us?

Scientists suspect that dolphins do not bleed or get infections because of their "dive reflex," which reduces blood flow. Natural antibiotics in the blubber ensure that no life-threatening infections occur. Similar to the giant panda on this list, we can use these antibiotics and learn a lot from their amazing healing properties.

2 Mammals in hibernation and synapse repair

The human brain uses synapses to relay signals from there neuron to neuron. This process is important for everything we do, from training to sleep. We have difficulty repairing damaged synapses, which is why neurodegenerative diseases are so dangerous. However, a recent breakthrough allowed us to observe synapses that experience considerable cooling, but still work after cooling down. Hibernating mammals accomplish this, although the study in question used artificially cooled mice.

The study was able to link a specific RNA-binding protein (RBM3), which was responsible for the recovery of synapses following severe body cooling. [10] When this protein is removed, the synapse repair is significantly reduced. These data support the necessary presence of RBM3 for synaptic and neuronal health as well as the potential for gene therapy to increase the production of RBM3 in patients with neurodegenerative diseases.

1 Scorpions and Brain Tumors

Scorpion venom is another type of poison that was not expected to help or harm humans. The scorpion in question is Leiurus quinquestriatus more commonly known as the Deathstalker. This name speaks of the nature of this scorpion – it is quite deadly. The mixture of neurotoxins in his poison is extremely dangerous. Let it sting and you'll need to be rushed to the nearest hospital.

In contrast to the aforementioned snake venom, the preparation used is derived directly from scorpion venom and is called chlorotoxin. This chemical can target brain tumors originating in the spine and brain. [11] The discovery of chlorotoxin has justified the study of other scorpion toxins, and more needs to be tested to see how effective the poison of other species is.

The treatment of tumors in the brain and spine is very risky. A wrong move, and the surgeon can cause irreversible damage. This makes chlorotoxin even more valuable. If we can fight tumors without being operated on, many risks are mitigated.
