I think it is feasible! ! ! ! ! ! ! ! You read 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 35 million years ago. This animal has two long tentacles and a hard shell. They like to live in the dark. As soon as they see the light, they immediately run around and disappear in a blink of an eye.
People hate this kind of animals, because they not only stink, but also spread diseases. Therefore, for many years, people's only attitude towards them is to destroy them and use various methods. But the hero of our program today, a 7-year-old gentleman, has a completely different attitude towards this animal from all of us. He regards them as his friends, not only unwilling to destroy them, but also keeping them delicious and delicious for more than 4 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 is located in the northwest of Yunnan Province, which is a thousand-year-old city. Nanzhao State in Tang Dynasty and Dali State in Song Dynasty used it as the capital. Dali has a long history, splendid culture and many celebrities, ranging from Duan's father and son written by Mr. Jin Yong to Yang li Ping, a famous dancer who danced in 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 is the director of the Institute of Pharmacology, Dali University, Yunnan Province, and he is 7 years old this year. You may not believe it, but 7-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 a cockroach is "cockroach". Also called Blattella, it is a very old insect.
Cockroaches first came from North Africa. They traveled to Europe on a boat from Finichi, and then spread all over the world. Now cockroaches can be found all over the world.
In people's minds, the cockroach is a pest that everyone hates and wants to make it extinct. So what kind of opportunity did Li Shunan start to pay attention to this pest? How did he turn this pest into wealth?
they appeared on the earth 35 million years ago; As long as it is organic food, wood, clothes, etc., almost all are eaten; They can survive for at least 1 minutes under vacuum; It is said that they are the only survivors after the nuclear explosion.
Dali was called "Ye Yu" in ancient times, so today the ancient city of Dali is also called "Yu City". Dali is the main settlement of Bai nationality. As far back as 4, years ago, the ancestors of the Bai nationality thrived here.
In p>1968, Li Shunan, who had just graduated from college, lived next to a Bai villager.
Li Shunan: An old man who lives with me, he carried water for a living. Later, after he fell, he became bone tuberculosis here in his hip joint. A fistula appeared on the skin outside the bone tuberculosis. This fistula was black in color and had a deep fistula.
Bone tuberculosis is what Chinese medicine calls "bone tuberculosis". This disease usually occurs in bones and joints. With this disease, first it will 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 a lot of western medicine to treat it, but it didn't work well. Later, I saw an old lady of ethnic minorities find him a pack of herbs for external application. Because this old man is an old man with five guarantees, there is no one else in his family, so I sympathize with him. When he changed his medicine, I went to help. I found that after using this herbal medicine, there was a miracle. His tuberculous fistula grew bright red granulation, and the granulation tissue grew 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 refractory disease. With drug treatment, the growth and spread of the fistula can only be controlled. To completely cure this disease, surgery must be adopted.
However, why can an ordinary rural woman's bag of herbs make 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 surgery is usually required. However, after he used this herb, the fistula healed quickly. At that time, I thought, why is this herb so strange? What is it?
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 kept an eye on it. After changing the medicine for his neighbor, he took the changed dregs home. In the evening, he began to ponder the ingredients in this herb.
Li Shunan: There are also fragments of plants in it, and it seems that I can still see animal carcasses and fragments, so I used a tweezer to separate the plant part from the animal part. After the animal part was separated, I used tweezers to clip it out bit by bit. It took about two hours to find out how there were insect feet, insect wings and some broken internal organs. After I put these things together, alas, they look like a cockroach.
there is a cockroach's body in the medicine! That sounds 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 people, among the Yi people, people are also used to crushing the body of cockroaches and applying it to the wound, especially for those wounds that have not been cured for a long time. This folk prescription has been tried and tested and won the trust of local people.
when it comes to cockroaches, most people think all the cockroaches they see are one kind. In fact, there are no fewer than 1 species of cockroaches in the world. There are more than 2 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 and so on.
In fact, the ancients had observed and studied cockroaches for a long time. So, what did they observe and study cockroaches? What did they find in the observation and research 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 34 million years. Even the radiation that can kill human beings can't kill them. Cockroaches have evolved a defense against toxic substances. It only takes six generations for them to be immune to pesticides. Looking around the world, no insecticide can have a long-term effect on cockroaches.
Li Shunan: Because I'm engaged in scientific research, I'm engaged in medicine, specializing in research, so I have to look up the literature and some information. First of all, I saw a report that there was an amber fossil in geological museum, England. The fossil geologist identified it as 3 million years old, but in the center of this amber, there was an insect whose shape was almost exactly the same as that of a cockroach now.
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 by C14 method and found that it has a history of 3 million years.
what is even more incredible is that cockroaches 3 million years ago are almost identical in appearance to cockroaches that exist today.
Li Shunan: At that time, I thought about why cockroaches 3 million years ago were basically the same shape as the cockroaches we see now, which proves that they can adapt to the changes of the earth. Generally speaking, organisms have to evolve. From 3 million years ago to now, their shapes may have changed greatly, but cockroaches have not. Why? At that time, I thought that this cockroach must have some substances in its body that can adapt to the damage caused by the earth's environment.
Cockroaches appeared on the earth 3 million years ago, and their appearance has not changed so far, except that the cockroach living in America today is about 1.5 inches long, while this ancient cockroach is 3.5 inches long.
As more and more information about cockroaches is collected, Li Shunan is more and more curious about cockroaches. What are the unknown secrets of cockroaches?
Maybe you have had such an experience. You found a cockroach at home, stepped on it and saw it dead, but when you looked for its body later, you found it was gone. Where did it go? Perhaps you won't think that it has escaped again!
According to the British Mirror, the cockroach has a very strong regenerative ability. Not only can it escape when people are unprepared after being injured, but it can survive for nine days even 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 wastebasket. 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 made a conclusion: if a nuclear explosion happens, all creatures in the affected area will disappear, only cockroaches will not become extinct! Because it is extremely viable!
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 when it is hungry, it can eat newspapers, eat books, and eat your books. Also, when there is no paper and books to eat, it can eat celluloid, the old record. After eating it, it can satisfy its hunger, so that's its strangeness. It has a particularly strong vitality.
Without food, cockroaches can live for a month, and without water cockroaches, they can only live for a week. 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, but also the ability of cockroach tissue repair is not small. Many stubborn and incurable wounds can be completely improved by applying some powder baked by cockroaches. Among the people, this method has been circulating for many years, and Li Shunan has seen many related records in such ancient books as Compendium of Materia Medica, Classic of Shennong Herbs, Fauna of Medicinal Animals in China, and National Compilation of Chinese Herbal Medicine.
Li Shunan: According to the Compendium of Materia Medica, cockroaches have the functions of promoting blood circulation, treating toxic sores and draining water. Therefore, in the classic works of traditional Chinese medicine, there are also records of the treatment of cockroaches, so I feel that our ancestors were not only folk, but also recorded in our ancient books of traditional Chinese medicine.
As a medicine, insects have a history of more than 2, years in China. According to the earliest text "Zhou Li", "five medicines, plants, insects and stones are also." It can be seen that ancient people have realized that "worm" is one of the medicinal materials. There are 29 kinds of insect drugs listed in Shennong Materia Medica Classic, and the Compendium of Materia Medica by Li Shizhen, a famous doctor in Ming Dynasty, expanded to 16 kinds. So far, there are as many as 3 kinds of medicinal insects in Chinese medicine, such as ants, bees, cockroaches, cicada shells, Mylabris, mantis, silkworm and flies.
since cockroaches are so useful, isn't it very profitable to keep cockroaches? Although the more you know about cockroaches, the stronger your curiosity will be. But cockroaches are pests after all. They live in unsanitary places and carry a lot of bacteria, viruses and parasite eggs. Therefore, even if cockroaches have so many magical abilities, if I tell you that your wound will be cured soon if you put some cockroaches on it, I don't think many people dare to accept this method, not only because people think it is disgusting, but more importantly, if you treat it directly with cockroaches, What should I do?
Cockroaches are tropical insects, so they are very afraid of cold. When the temperature drops below ℃, their lives will be seriously threatened and even die. So in winter, it will mostly move in a house with heating equipment.
cockroaches hide during the day and come out to look for food at night. It eats a lot and eats a lot of things.
It is precisely because cockroaches crawl everywhere and eat everything that they contaminate and swallow many pathogens. Coupled with their bad habit of pulling while eating, they become mechanical communicators of some pathogens.
Knowing that cockroaches can be used as medicine, Li Shunan, who studied pharmacology, decided to adopt a scientific method to raise cockroaches, and then separated the effective components in cockroaches one by one. That was in 1968, when he was 32 years old.
Li Shunan: There is nothing wrong with saying that cockroaches are pests, because they live in and carry a lot of bacteria, viruses and parasite eggs, so that's unscientific. We should get rid of the parts that are harmful to the human body in a scientific way, and then separate them one by one from the real cockroaches, which can promote cell regeneration, promote wound repair, and resist viruses and radiation.
In many people's homes in Yunnan, there is a cockroach called Periplaneta americana. This cockroach is reddish-brown, with a length of 25-4 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 cockroach in the house.
Li Shunan: At first, I made it in my own house. I threw away a wooden box containing my clothes and put it aside to make room for raising cockroaches.
Cockroaches like to live in warm, humid, food-rich and crevice places. Li Shunan keeps cockroaches in his suitcase.
In order to prevent the suitcase from being too stuffy and the cockroach from breathing, Li Shunan also opened a vent hole on the suitcase and specially set up a place to put food and water.
There is food and drink. Cockroaches live freely in Li Shunan's suitcase, and they breed very fast.
While raising cockroaches, Li Shunan began to prepare experimental instruments. But at this time, the problem also came.
Li Shunan: That was the most difficult time. At the beginning of the experiment, I had to do animal experiments first. I couldn't do experiments with people first. It was impossible and not allowed. When doing animal experiments, I can start experiments as long as I have a syringe. So after buying the syringe, there is no money to buy the boiling box, other devices, surgical devices and so on.
As we all know, syringes are usually used for injections and experiments, as well as boiling boxes for disinfection, gauze, surgical scissors, forceps, microscopes, centrifuges, etc., all of which are necessary instruments and equipment for animal experiments. However, at the beginning of the experiment, Li Shunan not only didn't have such big pieces as microscope and centrifuge, but even a small box for boiling syringes could not afford it. No way, he had to drink his own tea.
