The house is fully equipped with tables and chairs, and the materials used are also quite sophisticated.
Li Yu naturally lived in the main room in the north. Since he was the only one now, he directly used the east wing as a study.
At this moment, Li Yu sat at his desk, spread out the remaining manuscript paper, and began to meditate on what kind of article he should write and send to "Declaration".
Obviously, "Shenbao" is a news newspaper, and its main target is not professional groups, but the general public, so it will definitely not work if you write something too professional from the beginning, and it may be regarded as nonsense.
But if science popularization is written too simply, it will be meaningless; if it is written too in-depth, it cannot be solved in one article.
Li Yu thought for a long time and had no idea what to write, so he picked up the latest issues of "Declaration" that he got from Shi Liangcai yesterday and read them.
He can now read traditional Chinese very fluently. He practiced soft-pen calligraphy for several years when he was a child, and he has no problem writing traditional Chinese characters.
After reading two issues of the newspaper, Li Yu finally found inspiration from a report:
This is an article about two villages fighting for a hilltop with good feng shui as the village's graveyard. The article finally mentions that many villagers got sores after being injured in the fighting, and even the doctor could not save them. Many people died.
The main meaning expressed in the subsequent editorial is that villagers should not harm the harmony of their neighbors over trivial matters. As for the mention of wounds, sores and necrosis, it is more to raise the seriousness of the situation to alert the people.
However, Li Yu immediately knew from the sores on the wound that it was definitely caused by infection.
Naturally, the villagers use hoes and shovels for daily work. These tools are used for all kinds of work in the village. They are not only used for hoeing, but also used to clear the manure pits at home when they are blocked.
Li Yu lived in the village when he was a child. He remembers the old man saying that the old dry toilets in the past were all connected to pig pens, and if the pigs couldn't finish their poop, they would be hoeed into the ground. Naturally, cow dung and horse dung cannot be wasted, so they are all hoeed into the ground for fertilization.
Guo Degang once joked in a cross talk that Yu Qian's father, Mr. Wang, grows vegetables at home and only uses his own manure for fertilizer. In fact, there was no chemical fertilizer in the village before, and excrement was really the best farmyard fertilizer.
Healthy, natural and convenient!
However, if this kind of thing covered with feces and bacteria is used for fighting, it is very easy to get infected if wounds are made.
In the past, when the Mongolian army used bows and horses to conquer the world, they would poison the arrows. The so-called poison actually meant dipping the arrows in feces. This will make the wound very susceptible to infection after being hit by an arrow, and minor injuries can also lead to death of soldiers.
At that time, people had no idea that there were bacteria in feces. Even the West at that time had just realized that bacteria can cause diseases.
Li Yu decided to start here and explain the importance of disinfection in detail.
After all, when it comes to surgical trauma, disinfection is extremely important. In an era like the late Qing Dynasty, if disinfection was not carried out in time and infection resulted, there was really nothing that could be done.
The antibiotic miracle drug penicillin would not be put into mass use until at least 40 years later, during World War II.
Li Yu has also read a lot of time-travel literature about modern people going back in time and immediately researching and producing penicillin. In fact, this is really too difficult.
First of all, it is not easy to find the strain, and then how to increase the unit yield is the real big problem.
Fleming had discovered Penicillium in 1928, but he was unable to isolate penicillin himself.
It was not until ten years later, in 1938, that the German chemist Qian found Fleming's paper in a pile of old books. Then their team spent several years, cooperated with the military, used countless mice, and conducted countless experiments to increase the production of penicillin and obtain penicillin crystals.
It was not until around 1943 that mass production of penicillin could begin.
To put it simply, if you want to purify penicillin, you need a certain amount of luck and a lot of experiments. Not to mention bacterial strains, you don’t even know where to find those white mice.
Therefore, the only way to deal with infection now is prevention, and try to avoid wound infection in the first place.
Li Yu wrote down on paper some of the most commonly used disinfectants in modern medicine: medical alcohol, iodophor, iodine, sodium hypochlorite, and phenol. Fortunately, this is not complicated medical knowledge. I learned it in high school chemistry.
Then Li Yu eliminated them one by one, and only medical alcohol could be used. Although the other four were more effective, ordinary medical clinics in the late Qing Dynasty obviously did not have the conditions to produce these chemicals.
The concentration of medical alcohol is only higher, and its preparation method is not much different from that of wine making.
Don’t underestimate alcohol disinfection, which is now common sense. In fact, it was not until two years later, in 1904, that humans realized that alcohol can disinfect.
With this topic in mind, Li Yu immediately thought about it and quickly wrote the article.
First of all, he called on all medical centers to be clean and use soap to improve hygiene. If it involves trauma treatment, it is even more important to ensure that the wound is clean.
Li Yu took the trouble to introduce the pasteurization method in detail, and it is very simple to operate. According to the concept of pasteurization, if it is some liquid that needs to be drunk, just heat it to 60 degrees Celsius. But there were no thermometers at that time, and most of the things used in medical clinics for heating were appliances, so it was easier to heat them directly in boiling water.
Then he wrote that high-concentration wine can be used to disinfect wounds. He emphasized the high concentration, for fear that the doctor would just use ordinary white wine. Li Yu originally wanted to write about the concentration out of rigor, and 75% was definitely the best, but suddenly he thought it would be better to ask them to increase the concentration as much as possible. After all, there was no measuring meter, and at that time, the highest degree of distilled liquor was about this level. . So first of all, it can be promoted simply and effectively, otherwise the medical center will definitely not do it if it is too difficult.
Furthermore, applying alcohol directly to the wound will cause strong irritation and pain, but there is no iodine! It's better to be in pain than to lose your life.
In order to improve credibility, Li Yu also made up some examples of disinfection and non-disinfection to compare. Anyway, there have been many such things in later generations, so it cannot be said to be fabrication!
The article was written quickly, and Li Yu finished it in less than two hours.
It seems like common sense, but for the time, it was the latest scientific research results in the past ten or twenty years!
In fact, realizing that diseases have causes was already a major advancement in human civilization at that time. In the early years, many people, both in the East and the West, believed that getting sick meant provoking ghosts and gods. Otherwise, there wouldn’t be so many wizards, witches and magicians performing various exorcisms.
After writing the article, Li Yu stretched hard, and then went to Jinyu Alley to find Ding Deshan, the founder of Donglaishun, who was still setting up a noodle stall.
Don't tell me, Li Yu didn't know what craftsmanship was until he ate his noodles. In a good mood today, Li Yu ordered a bowl of haggis noodles and a large plate of mutton.
When Li Yu returned to his residence burping, he happened to see Shi Liangcai arriving.
Li Yu showed him the article, which was not very deep. Shi Liangcai understood it completely and just asked: "Is this really okay?"
"Absolutely no problem! How could I make fun of people's lives! Don't worry, foreign doctors are doing routine work in the hospitals in the concession." Li Yu affirmed.
"With your words, I feel relieved!" Shi Liangcai thanked him, "I didn't expect that sir also has a benevolent heart as a doctor."
Li Yu laughed and said, "You've got a reward, I don't understand medicine, I just know a little bit about microorganisms."
"microorganism?"
"Well, this is hard to explain. Anyway, believe me, you're right!"
