I think it's feasible! ! ! ! ! ! ! ! Look at the following article, which is the source of the article ~ ~

There is an animal that appeared on the earth earlier than dinosaurs. According to research, they appeared 350 million years ago. This animal has two long antennae and a hard shell. They like to live in the dark. As soon as they saw the light, they ran around and disappeared in the blink of an eye.

People hate this kind of animals, because they not only stink, but also spread diseases, so for many years, everyone's only attitude towards them is to destroy them and use various methods. But the hero of our program today, a 70-year-old man, has a completely different attitude towards this animal from all of us. He regarded them as his friends, not only unwilling to destroy them, but also kept them delicious for more than 40 years. You may not believe it at all. Now, this animal is bringing him endless wealth.

When it comes to Dali, people immediately think of Cangshan Mountain, Erhai Lake and the beautiful butterfly spring. Dali Bai Autonomous Prefecture, located in the northwest of Yunnan Province, is a thousand-year-old city. Nanzhao State in the Tang Dynasty and Dali State in the Song Dynasty all took it as their capital. Dali has a long history, splendid culture and a large number of celebrities, from Duan's father and son in Jin Yong's works to a famous dancer who dances peacock dance. Today, I'm afraid not many people know the name we want to mention to you, but the value he created far exceeds people's imagination.

Li Shunan, director of the Institute of Pharmacology of Yunnan Dali University, is 70 years old this year. You may not believe it, but 70-year-old Li Shunan has been thinking about an animal for 45 years. So far, this animal has brought a steady stream of wealth to many people. So, what animal is it? Today, Professor Li Shunan took us to a Periplaneta americana farm that meets international standards. What is Periplaneta americana?

The so-called Periplaneta americana is actually a cockroach. The scientific name of cockroach is "cockroach". Also called cockroach, it is a very old insect.

Cockroaches first came from North Africa. They came to Europe by boat from Finich and then spread all over the world. Cockroaches can be found all over the world now.

In people's impression, cockroach is a pest that everyone hates and wants to make it extinct. So from what opportunity did Li Shunan begin to pay attention to this pest? How did he turn this pest into wealth?

They appeared on the earth 350 million years ago; As long as it is organic food, wood, clothes, etc. Almost all of them were eaten; They can survive in vacuum for at least 10 minutes; It is said that they are the only survivors after the nuclear explosion.

Dali was called "Yu Ye" in ancient times, so today the ancient city of Dali is also called "Yucheng". Dali is the main settlement of Bai nationality. As early as more than 4000 years ago, the ancestors of the Bai nationality flourished here.

1968, Li Shunan, who just graduated from college, lived next door to a Bai villager.

Li Shunan: An old man who lives with me. He carries water for a living. Later, after he fell, he became bone tuberculosis here at the hip joint. Fistula appeared on the skin outside the bone tuberculosis. This fistula is black in color and has a deep fistula.

Bone tuberculosis is what Chinese medicine calls "bone tuberculosis". This disease usually occurs in bones and joints. With this disease, it will first fester, and then the diseased part will gradually fester. Over time, the diseased part will eventually form a fistula, which is difficult to cure.

Li Shunan: I used many western medicines to treat it, but the effect was not good. Later, I saw an old lady of ethnic minorities find him a pack of externally applied herbs. Because this old man is a five-guarantee old man and there is no one else at home, I feel sorry for him. I'll help him when he changes his dressing. I found a miracle after using this herb. His tuberculous fistula has bright red granulation, and the granulation tissue grows very fast. In less than two weeks, his fistula healed and grew well.

Li Shunan is a medical student. He knows that the fistula of bone tuberculosis is a very difficult disease. The growth and spread of fistula can only be controlled by drug treatment. Surgery is necessary to cure this disease completely.

However, why can an ordinary rural woman's bag of herbs have an unexpected miraculous effect on a refractory disease?

Li Shunan: According to general medical knowledge, tuberculous fistula will not heal after long-term treatment, and usually requires surgical treatment. However, after he used this herb, the fistula soon healed. At that time, I thought, why is this herb so strange? What is this?

Li Shunan found the old man who delivered the medicine and asked her for a prescription. But the old lady didn't tell him the answer.

Later, Li Shunan left an eye. After changing the medicine for his neighbor, he took the changed dregs home. In the evening, he began to ponder the composition of this herb.

Li Shunan: There are fragments of plants in it, and I seem to see the dead bodies and fragments of animals, so I use tweezers to separate the plant parts from the animal parts. After the animal parts were separated, I used tweezers to clip them out bit by bit. It took about two hours to figure out why there were insect feet, wings and some broken internal organs. When I put these things together, alas, they look like a cockroach.

There is a cockroach's body in the medicine! That sounds very fresh. In fact, in the folk, especially in many ethnic minority settlements, people have the habit of using animals as medicine. In addition to the Bai nationality, in the Yi nationality, people are also used to crushing the body of cockroaches and applying it to wounds, especially those that have not healed for a long time. This folk prescription has won the trust of local people.

Speaking of cockroaches, most people think that the cockroaches they see are all one kind. In fact, there are no fewer than 10000 species of cockroaches in the world. There are more than 200 species of cockroaches recorded in China, but most of them live in forests and feed on fallen leaves and rotten wood. Only a few kinds of cockroaches like to live in people's homes. In China, the most common cockroaches in the family are: Periplaneta americana, periplaneta fuliginosa, Periplaneta australis, Periplaneta japonica, Blattella germanica, etc.

In fact, the ancient people's observation and research on cockroaches have a long history. So, what kind of observation and research have they made on cockroaches? What did they find in their observation and study of cockroaches?

Cockroaches are one of the successful examples in evolutionary history. They escaped the rule of dinosaurs and spread to the whole earth in 340 million years. Even radiation that can kill humans can't kill them. Cockroaches have evolved the ability to resist toxic substances. They only need six generations to be immune to pesticides. Looking around the world, no insecticide can have a long-term effect on cockroaches.

Li Shunan: Because I am engaged in scientific research, I am engaged in medicine, specializing in research, so I have to check the literature and some materials. First I saw a report that there was an amber fossil in geological museum, England. Fossil geologists have identified it as 300 million years old, but in the center of this amber, there is an insect whose shape is almost exactly the same as that of today's cockroaches.

Li Shunan is talking about this fossil. It was discovered by American scientists in a coal mine in eastern Ohio. Later, scientists tested this fossil with C 14 method and found that it has a history of 300 million years.

What is even more incredible is that cockroaches 300 million years ago are almost identical in appearance to cockroaches that exist now.

Li Shunan: At that time, I was wondering why cockroaches 300 million years ago were basically the same shape as the cockroaches we see now, which proved that they could adapt to the changes of the earth. Generally speaking, organisms have to evolve. From 300 million years ago to now, the shape may have changed a lot, but cockroaches have not. Why? At that time, I thought that there must be something in this cockroach that can adapt to the damage caused by the earth's environment.

Cockroaches appeared on the earth 300 million years ago, and their appearance has not changed so far, except that cockroaches living in America today are about 1.5 inches long, while this ancient cockroach is 3.5 inches long.

More and more information about cockroaches has been collected, and Li Shunan's curiosity about cockroaches is increasing day by day. What are the unknown secrets of cockroaches?

Maybe you've had this experience. You found a cockroach at home, stepped on it and saw it dead, but when you looked for its body, you found it was gone. Where did it go? Maybe you wouldn't think it ran away again!

According to the British Mirror, cockroaches have very strong regenerative ability. It can not only escape when people are unprepared after being injured, but also survive for nine days after being beheaded. Once, a British scientist did a related experiment. He cut off the head of a pregnant female cockroach. After a while, he found that the cockroach that had been placed on the test bench was gone, so he rummaged around and finally found the headless cockroach in a wastepaper basket. At this time, he found that the cockroach was still alive, not only alive, but also gave birth to several small cockroaches.

According to the ecological habits of cockroaches, some biologists abroad have come to a conclusion: if there is a nuclear explosion, all the creatures in the affected area will disappear, except cockroaches! Because it is highly feasible!

Small cockroaches and adult cockroaches eat the same food. Meat and starchy foods are their favorites.

Li Shunan: It eats everything. It is omnivorous. Even if it is hungry, it can eat newspapers, books and your books. Also, when there is no paper or books to eat, it can eat celluloid and old records. After eating it, it can satisfy its hunger, so this is its strangeness. It has a strong vitality. You can't starve it.

Cockroaches can live for a month without food, and only a week without water cockroaches. So don't scream when you see a headless cockroach crawling around on the floor, because cockroaches can live for a week without their heads and even have children.

Not only that, the cockroach's tissue repair ability is not small, and many stubborn wounds can be completely improved by applying some cockroach yeast powder. This method has been circulated among the people for many years, and Li Shunan has also seen many related records in ancient books such as Compendium of Materia Medica, Shennong Materia Medica, China Medicinal Animals, and National Compilation of Chinese Herbal Medicine.

Li Shunan: According to Compendium of Materia Medica, cockroaches have the functions of promoting blood circulation, treating toxic sores and draining water. Therefore, in the classic works of Chinese medicine, there are also records of cockroach treatment, so I feel that our ancestors recorded cockroach treatment a long time ago, not only among the people, but also in our classic Chinese medicine.

In China, insects have been used as medicines to treat diseases for more than 2,000 years. According to the earliest text "Zhou Li", "Five medicines, plants, insects and stones." It can be seen that the ancients have realized that "worm" is one of the medicinal materials. There are 29 kinds of pesticides listed in Shennong Materia Medica, and the Compendium of Materia Medica by Li Shizhen, a famous doctor in Ming Dynasty, expanded the number of pesticides to 106. Up to now, there are as many as 300 kinds of medicinal insects in Chinese medicine, such as ants, bees, cockroaches, cicadas, Mylabris, mantis, silkworms and flies.

Since cockroaches are so useful, isn't it very profitable to raise cockroaches? Although the more you know about cockroaches, the more curious you will be. But cockroaches are pests after all. They live in unsanitary places and carry a lot of bacteria, viruses and parasite eggs. So, even if cockroaches have so many magical abilities, if I tell you that your wound will be cured soon, I think many people are afraid to accept this method, not only because people think it is disgusting, but more importantly, what should I do if you treat it directly with cockroaches?

Cockroaches used to be tropical insects, so they are very afraid of cold. When the temperature drops below 0℃, their lives are seriously threatened and even die. So in winter, it mostly moves in houses with heating equipment.

Cockroaches hide during the day and come out for food at night. It eats a lot, eats a lot of things.

It is precisely because cockroaches crawl everywhere and eat everything that they pollute and swallow a lot of pathogens. Coupled with their bad habit of eating and pulling things, they have become mechanical communicators of some pathogens.

Knowing that cockroaches can be used as medicine, Li Shunan, who studied pharmacology, decided to adopt scientific methods to raise cockroaches, and then separated the effective components in cockroaches one by one. That's 1968. He's 32 years old.

Li Shunan: There is nothing wrong with saying that cockroaches are pests, because they live and carry a lot of bacteria, viruses and parasite eggs, so this is unscientific. We should remove the harmful parts of human body by scientific methods, and then separate them from the real cockroaches one by one. Cockroaches can promote cell regeneration, wound repair, antivirus and radiation resistance.

In many people's homes in Yunnan, there is a cockroach called Periplaneta americana. This cockroach is reddish-brown, with a body length of 25-40 mm and a large black-brown butterfly spot on the back plate of the chest. It is the biggest cockroach in the room.

After screening, Li Shunan decided to breed the big-headed cockroach in this family cockroach.

Li Shunan: I made it at home at first, so I threw away a wooden box with my own clothes and put it aside to make room for cockroaches.

Cockroaches like to live in warm, humid, food-rich and crevice-filled places. Li Shunan keeps cockroaches in his suitcase.

In order to prevent the suitcase from being too hot for cockroaches to breathe, Li Shunan also opened a ventilation hole in the suitcase and set up a special place for food and water.

Eating and drinking, cockroaches live freely in Li Shunan's suitcase and multiply very fast.

While keeping cockroaches, Li Shunan began to prepare experimental instruments. But at this time, the problem has come.

Li Shunan: That was the most difficult time. At the beginning of the experiment, I have to do animal experiments first. I can't do experiments on people first. This is impossible and not allowed. When doing animal experiments, I can start experiments as long as I have a syringe. So after buying syringes, there is no money to buy boiling boxes, other instruments, surgical instruments and so on.

As we all know, syringes are usually used for injection and experiments, as well as boiling boxes for disinfection. In addition, gauze, surgical scissors, tweezers, microscopes and centrifuges are all necessary instruments and equipment for animal experiments. However, at the beginning of the experiment, Li Shunan not only didn't have such big things as microscopes and centrifuges, but even a small box with boiling syringes could not afford it. No choice, he had to clean the tea jar for drinking water and use it to cook needles and needles, but not all machines can make do like this. For example, laboratory animals, microscopes and centrifuges must cost money. what should he do ？

Li Shunan: What should I do? Just now, I said that I go to Zhou Hospital to sell blood once a month, and I can buy a lot of things by selling blood for about 300 yuan at a time. But after I sold my blood, I went to work the next day and pulled a rickshaw.

When it comes to selling blood to make money and then buying experimental equipment, Li Shunan looks calm. He told us that with the progress of the experiment, more and more equipment was needed. In those years, when he came home at night, he would do experiments. At dawn, he had to rush to the dock and the station to work as a porter. So in those years, I often went to buy experimental equipment as soon as I got the money. When he is really short of money, he will sell blood again.

In this simple, repetitive and monotonous rhythm, as the days passed, Li Shunan raised more cockroaches. But at this time, new problems appeared again.

Li Shunan: Especially in chemistry, we find it difficult to go deep, because the chemical composition in cockroaches is very complicated, so we have to think that we must organize a team and invite people with high-level chemical analysis ability to participate in this work.

Cockroaches are easy to find, tenacious in vitality and large in reproduction, so it is not difficult to raise cockroaches. But the chemical composition of cockroaches is more complicated. What ingredients play a role in the treatment of diseases? What ingredients can be omitted? For a long time, the analysis of chemical composition of cockroaches has puzzled Li Shunan.

By chance, he found Kunming Institute of Botany, Chinese Academy of Sciences.

Li Shunan: Later, we looked around and found a very capable researcher at Kunming Institute of Botany, Chinese Academy of Sciences. Researcher Hu Zhong, because he is engaged in biochemistry, has made great achievements in this biochemistry. Their equipment is better, and the equipment of the Institute of Botany is recognized nationwide. Their chemistry level is very high, so he finally found Professor Hu Zhong.

Cockroaches have a good effect on wounds among the people. Li Shunan decided to extract effective components from cockroaches. What should he extract? Is to extract its effective chemical components. However, the extraction of chemical components is a very difficult task. For Li Shunan, whose income was meager at that time, without capital and technology, the difficulties could be imagined. Therefore, when Li Shunan found Professor Hu Zhong from China Academy of Sciences, he was very excited.

So they cooperated, and later some young comrades took part in the research one after another. It took them more than 10 years to finally extract the effective components to promote wound healing and make them into traditional Chinese medicine preparations. But how effective is this medicine? Can it really promote the rapid healing of wounds?

According to the national regulations, a new drug can only be officially approved to enter the human clinical trial stage after the animal test is successful. Before the formal human trial, Li Shunan decided to try the drug himself.

Li Shunan: I used that electric soldering iron. When it burned red, I burned my leg.

Li Shunan: After the burn, there was about one, the wound was about the size of an olive, and there was a hole. Then after the new drip recovered, it became swollen the next day. It was red and swollen at first, but then it disappeared. On the third day, its granulation began to grow. It took about a week to ten days to fix it. Finally left a slight scar here.

With the success of the experiment, the market demand for drugs is increasing, and the original narrow laboratory can no longer meet the production requirements.

After obtaining the national invention patent and new drug certificate, Li Shunan sold the cockroach breeding technology and extraction process to domestic pharmaceutical companies. Nowadays, Chinese medicines made from Periplaneta americana are mass-produced in four domestic pharmaceutical factories. According to the statistics of a pharmaceutical factory, the annual sales output value is 42 million yuan, and the annual economic value created has reached10 million yuan.

Nowadays, breeding cockroaches has become a new industry in Dali and Xichang. One enterprise produces hundreds of billions of cockroaches. Professor Li is responsible for providing feed formula and the breeder is responsible for taking care of cockroaches. More and more people have changed the idea that cockroaches are heinous pests, and more and more people are learning to raise cockroaches because cockroaches bring wealth to people!
