"I'm just telling you! Why would Professor Han casually investigate me? It turns out that you people are the ones who made the decision on your own. You must make it clear in the future about this kind of thing. This will greatly affect Professor Han's glorious image in our hearts." Shang Xiaoyang smiled.
.
Chang Yunyan's face was full of black lines: "Professor Han is a huge pit, a divine pit, haven't you heard of it? I'm leaving, I won't tell you anymore, you can take care of yourself."
"Do I want to take care of myself? I think you swallows have to take care of yourself. I never thought that the goddess in my mind would actually want to engage in intelligence. I wonder if they would give away their appearance for the sake of intelligence? In order to be given, I have to work hard. If
If I had not performed well this time, how could Xiaoyanzi pay attention to me? Science and technology are the primary productive forces!"
After sighing, Shang Xiaoyang hurriedly called home. This time, he didn't ask anyone to call him "little sister". Instead, he went directly to his second uncle and third uncle and told them to book flights today and let them fly to Magic City tomorrow.
, he has already made arrangements here. There are good ways to treat his father's illness in the magic city.
After repeated questioning by his two uncles, Shang Xiaoyang briefly talked about his recent experiences before hanging up the phone.
He didn't know the impact of his words on their village, but his second uncle and third uncle saw that they could earn millions of yuan before graduating from the university, so it was absolutely right to send their children to school.
Not only did they have money, but their eldest nephew also promised that they could cure their eldest brother's illness. The news spread throughout the village in an instant.
When Shang Xiaoyang's father heard the news, he who was originally depressed immediately became energetic. His son was a great talent. He believed his son's words. Since his son said that his disease could be cured, he would not die.
.
With the belief to live, the whole person's energy and spirit are different. Seeing such changes, the hospital can only express admiration, so the disease is not terrible, but the terrible thing is that the patient has lost the confidence to live.
Although Shang Xiaoyang couldn't see the situation at home, he could imagine it, so he safely opened Lin Yu's computer and searched for everything about sharks. He was really curious about the relationship between sharks and cancer.
So far, cancer is still one of the major diseases that threatens human life. I have never heard of anyone who can cure cancer. It seems that scientists have not found a specific drug to treat cancer. Therefore, looking for anti-cancer drugs has become a
A formidable fortress in science.
However, after checking the relevant information about sharks, Shang Xiaoyang found that sharks are indeed very special. Shark bodies are extremely healthy. Even if they suffer great trauma, they can recover quickly without any inflammation. Not to mention
Infectious Diseases.
The famous American Ph.D. in biochemistry, Ruhl, works at the world-famous Mart Marine Laboratory. He has conducted long-term research on the physiology and pathology of sharks.
Over the past 25 years, he has conducted pathological anatomy studies on 5,000 sharks and found only one shark with a tumor, and it was a benign tumor.
According to the National Lower Animal Tumor Registry in the United States, sharks have the lowest cancer rates in 16 years of records.
Ruhl also found that of the more than 25,000 sharks surveyed by scientists, only five had tumors.
Ruhr's discovery aroused scientists' great interest in sharks, and scientists from various countries began to study sharks.
Scientists in Florida, USA, used an extremely powerful carcinogen, aflatoxin, to feed sharks.
In nearly 8 years of feeding experiments, not a single tumor was found in any shark, which shows that sharks have extremely strong anti-cancer abilities.
So, what is shark’s secret against cancer?
Some scientists believe that the shark's anti-cancer secret is that its muscles can produce a chemical substance that can inhibit the growth of cancer cells, making it less susceptible to cancer.
Dr. Ruhl believes that the liver of sharks can produce a large amount of vitamin A. Experiments have shown that vitamin A can differentiate epithelial cells that have just begun to become cancerous and restore them to normal cells.
So Rule thinks the secret weapon in protecting sharks from cancer is vitamin A.
Other scientists believe that an anti-cancer substance can be produced in the blood of sharks. Scientists from the Shanghai Institute of Fisheries in my country also support this view. In 1984, they collected blood from the hearts of sharks and extracted a certain concentration of serum. Then inject it into human erythrocyte leukemia cell lines (a type of blood cancer).
After a period of time, they found that the normal metabolism of some cancer cells was destroyed and most of the cancer cells died.
This shows that shark serum has the effect of killing human erythrocyte leukemia tumor cells. It can be seen that shark blood contains anti-cancer substances.
Some scientists believe that there is a secret weapon in the cartilage tissue of sharks. In the past, scientists have discovered that calf cartilage has certain anti-cancer effects.
In 1982, Langel, a scientist at the Massachusetts Institute of Technology in the United States, discovered in his research that shark bones are entirely composed of cartilage.
There is a compound in these cartilage tissues that can block the blood vessel network around the cancer. It can cut off the supply of cancer cells and cause the cancer to shrink. It can also kill the cancer cells.
He confirmed through experiments that the substances in shark cartilage can completely prevent the growth of cancer cells without any side effects, and its anti-cancer effect is 100,000 times stronger than the substances in calf cartilage.
Scientists from Harvard University in the United States tried shark cartilage extract to treat 32 late-stage cancer patients. As a result, 11 patients were cured, and the remaining patients' cancers also shrank significantly.
Contras Hospital in Mexico used shark cartilage extract to treat 8 patients with advanced cancer, and their cancer cells shrank by 30% to varying degrees.
In addition to these, research on sharks is far from over. Molecular biologist Zaslov believes that sharks’ anti-cancer weapons are in the stomach.
In his experimental research, he found that the stomach of sharks can secrete an antibiotic called "keratine", which has a stronger bactericidal effect than penicillin. It can also kill protozoa and fungi at the same time, and can also resist AIDS and cancer.
.
These conclusions are really diverse. What the secret weapon of sharks against cancer is is still a mystery.
And these conclusions are also controversial. Some people still say that sharks cannot fight cancer and that sharks themselves can get cancer. Saying that sharks can fight cancer is a lie told by American scientists in the last century for profit.
According to a recent report by Russian News Network, Gary Ostrander, a professor at the Department of Biology and Comparative Medicine at Johns Hopkins University in the United States, pointed out in a recently published research report that sharks can also suffer from cancer.
At the same time, eating shark cartilage has no obvious effect on treating cancer. Professor Gary Ostrander believes that the current trend of eating shark cartilage is just a victory of "pseudoscience" through marketing.
He said that eating shark cartilage is not only useless for treating patients, but also causes great harm to shark populations. Patients often blindly believe in the efficacy of these cartilages and refuse other treatment methods. Massive hunting activities have also reduced the number of sharks.
of rapid decline.
American scientist John Hasbarger also pointed out at the 91st Annual Meeting of the American Anti-Cancer Society that sharks can get cancer.
Haasbarger, a scholar at the National Cancer Institute, discovered 50 types of cancer in cartilaginous fish, 23 of which came from various sharks, and some of them grew directly in cartilage.
It is worth noting that these people not only do not recognize the anti-cancer effect of sharks, but also refer to Dr. William Lance, the author of the book "Sharks Don't Get Cancer" (he can be regarded as the father of "shark therapy").
He also brought it up and said that the author recently admitted that sharks can actually get cancer.
He also said that the author confessed to the outside world that his conclusion that shark cartilage extract could treat cancer was only based on the results of a few extremely limited experiments.
But this is obviously not close to the truth. In recent years, more and more scientists have become interested in the anti-cancer properties of shark cartilage. Many scientists have also discovered that sharks can actually get cancer, but Dr. William Lance has not
There is no saying that sharks are absolutely cancer-free.
In recent years, there have been fewer and fewer related studies in this area. Especially in 2000, Dr. John Hasburg pointed out that there have been more than 40 cases of sharks with cancer in their research, including even those with cancer.
Examples of cartilage cancer.
His supporters claim that "Sharks Don't Get Cancer" only selectively touches on a small number of examples that contribute to this argument, and that the book is very poorly written.
They also called on people to stop killing sharks in order to obtain shark cartilage, thereby destroying the biological chain and paying a higher price.
But soon, Dr. William Lance also responded to this report. He believed that it was nonsense to completely dismiss the role of shark cartilage in cancer treatment.
He said that the original work "Sharks Cannot Get Cancer" had already pointed out that 30 tumors were found in 7,500 sharks in the study, but this is not inconsistent with the anti-cancer effect of shark cartilage.
The main purpose of people hunting sharks is to obtain shark meat for consumption, and shark cartilage is only a by-product.
Although the myth that sharks are immune to cancer has been shattered, research on shark cartilage continues, albeit much less. In addition to shark cartilage, scientists have discovered that cow cartilage also contains substances similar to shark cartilage.
In fact, sharks do have strong anti-infection capabilities, and their wound healing ability is twice that of humans. However, many people are not sure whether their cartilage has anti-cancer effects.
Regardless of whether sharks can cause cancer, whether they can fight cancer, or whether the anti-cancer effect is obvious or not, it would be absolutely a mistake to completely deny it.
Research on shark cartilage actually has a history of many years. Many scientists in Canada, the United States, and Japan have conducted experiments on multiple species of sharks.
They injected large doses of chemical carcinogens into sharks, but no tumors developed in the sharks. This is true.
Based on these arguments, in addition to studying the medicinal properties and extraction of Chinese medicinal materials, the pharmacology laboratory of Han Kongque and Modu University of Science and Technology has recently launched two other projects on snake venom and shark venom.
