Extended data:
Although medical science has proved that cockroaches carrying a large number of germs can cause many diseases of human beings, British scientist Simon Lee said that cockroaches bring more benefits than disadvantages to human health, because at this time we can only rely on them to fight against superbugs. ?
Research by the University of Nottingham in the United Kingdom shows that the nervous system tissues in the brains of cockroaches and locusts can destroy 90% of superbugs or enteroviruses without destroying human cells. Simon, who is in charge of this research, put forward this view at the autumn seminar on microbiology held at Nottingham University from 6 to 9 this month. ?
Simon said that the current drugs can't kill superbugs, and once they are successfully developed and manufactured, they may replace some existing antibiotics in the future. Some people think that because these insects often live in an extremely unsanitary environment, they have many different antibodies to protect themselves from different types of bacteria to avoid being attacked by microorganisms. ?
Cockroaches look disgusting, but some women who love beauty may put cockroach juice on their faces all day long, without knowing it. Almost all high-end cosmetics in Japan and South Korea contain chitin extracted from cockroaches. ?
There is a substance called chitin in cockroach epidermis, which has the function of moisturizing. At the same time, there is a substance called antibacterial peptide in cockroaches, which can resist germs and has antibacterial effect when applied to the face. After using cosmetics containing cockroach juice, women feel tender and tender. ?
The price of chitin is very high, so in our country, it is only used for wound healing, and it has not been popularized in the manufacture of high-end cosmetics.
