The Angel Who Saved Lives 1
" Coo coo ". Following the release of the pigeon," Achoo-" the little fly shook its head and touched its throat with its hand. "Hehe, did you catch a cold again?"”"It looks like my tonsil is inflamed, swollen and painful."”"Sigh, last time I had a bad cold, it was all thanks to you that I took amoxylin capsules. The effect was pretty good." You can try." "It should be possible. This was a penicillin-type drug, and the effect was indeed quite good. Hey, do you know who the inventor is?”"Hehe, I really don't know. I don't think you know either." "Hahaha, trains are not pushed, Mount Tai is not piled up, and bragging is not bragging. I really wasn't trying to be high-profile. "Listen to me, I'll tell you slowly," Little Fly immediately chanted.
Did it need to be foggy every day to block the sky? Did he need a thunderstorm to wet his heart? Do you need a vial of adrenaline mixed with the juice of spring to inject into your cold meridians? And you sing the song of the nightingale to the carp that sleeps in the pool. Discovering it was completely by chance, but purifying it was very difficult. There were countless people who had saved people, so how many elites would be indifferent?
As everyone knew, this type of Penicillins was also known as Penicilin G, PeillinG, Penicilin, Penicilin, Penicillin-Na, Penicillin-Na, Penicillin-K, and Penicillin-K. Penicillins were a type of antibiotics. They were extracted from penicillins and contained penicillins in their molecules. They could destroy the cell walls of bacteria and kill bacteria during the reproductive period of the bacteria. They were the first antibiotics that could treat human diseases. Penicillins were a general term for a large class of beta-lactams. Penicillins were the first antibiotics discovered in human history, and they were widely used. As early as the Tang Dynasty, tailors in Chang 'an City would apply paste with green hair on their fingers cut by scissors to help the wound heal. It was because the substance produced by green hair (Penicilin bacteria) had a disinfectant effect. This was the earliest known record of people using Penicilin.
The story had to start here:
In England, there was a poor farmer named Fleming. He was kind and helpful. Once, when he was farming in the fields, he suddenly heard someone crying for help in the nearby swamp area." Who is it?”He immediately put down the farming tools in his hand and quickly ran to the edge of the swamp. Aiyo, he found a boy falling into the manure pit. He hurriedly saved the boy and saved his life. Two days later, an elegant gentleman drove a gorgeous carriage to the farmhouse where Fleming lived. He introduced himself politely and said that he was the father of the boy who had been rescued. He came to thank him. The gentleman offered to repay him with generous gifts, but the farmer insisted on refusing. He repeatedly stated,"I can't accept payment for saving your child.”Just as they were pushing each other, a handsome young man suddenly walked in from outside. The gentleman glanced at him and asked,"Is this your son?" The farmer nodded happily.”The gentleman continued," Well, since you saved my son, let me do my best for your son. Let's make an agreement. Please allow me to take your son away. I want him to receive a good education." If this child is as kind as his father, then he will definitely become someone you can be proud of in the future.”In view of the gentleman's sincerity, the farmer had no choice but to agree to his proposal. The gentleman was very trustworthy and kept his promises. Not only did he send the farmer's child to school, but he also provided for him to go to St. Mary's Medical College until he graduated.
This farmer's child was none other than Professor Alexander Fleming, a famous British biologist. He first invented the world-famous penicillin in 1928. Later, it was further improved by the British pathologist Florey and the German biologist Chane. It was used in clinical practice in 1941 and gradually promoted in 1943. Penicilin was recognized as the third major invention in the Second World War, alongside radar. The gentleman mentioned above was the British House of Lords 'member, Winston. His son, who was rescued by a farmer, later became a famous British politician and Prime Minister during World War II, Sir Winston. Hehe, no one expected that a farmer saving a child he didn't know would have such a major impact on future generations. His own son also obtained the opportunity to receive higher education. In the future, he would actually become a famous British Bacteriologist and inventor of penicillin. There was no need to go into details about Prime Minister Winston Churchills 'outstanding achievements in World War II. Professor Fleming's invention of penicillin had saved countless lives that could not be saved in the past. It had really benefited all mankind. In this sense, the reward that the benevolent farmer, Fleming, received was the highest and most generous. It could also be said to be unparalleled in the world!
Fleming was born on August 6, 1881, in a farm in Elsa, England. Alexander Fleming was a small Scottish man with bright eyes and a bow tie on his shirt collar. Every elementary school student had read the legendary story of Fleming. He discovered the Penicillin-type mold in a petri dish. They overcame technical difficulties one after another, fought against many skeptics for a long time, and finally won. The invention of penicillin became the greatest pioneering work in the medical world of the 20th century. His father was a manor owner who loved natural science, and his brother was a doctor. Ever since he was young, Fleming had been influenced by his father and brother and had made up his mind to become a doctor. Just as Fleming was ambitious enough to make a name for himself in the field of infectious diseases, the First World War broke out. He went to the battlefield hospital to treat infected wounds. He shifted his passion for research to the prevention and treatment of wound infection. Because of his and his colleagues 'excellent work, the field hospital he worked in became the best hospital to prevent wound infection. After the war, Fleming returned to his alma mater as a lecturer in bacteria. At the same time, he went to Wright's incubation station to do his beloved research on killing bacteria. Fleming and his assistant focused their research on staph because it was a widely distributed and harmful pathogen. It was often the cause of wound infection and suppuration. They worked very hard. They spent all day in a simple laboratory, inoculating staph bacteria in petri dishes, artificially cultivating them, and then testing the effects of various drugs on staph bacteria in order to find the ideal drug to kill staph bacteria.
In 1921, an accidental phenomenon suddenly attracted Fleming's attention to a previously unknown biological reagent that could dissolve bacteria. Fleming and his assistant thought that lysysozymes were an important vaccine or effective drug. However, after seven years of dedicated research, they failed. Lysozymes had almost no effect on pathogenic organisms. There were always failures in scientific research, and in fact, this failure had opened the door to Fleming's discovery of penicillin.
In the summer of 1928, the weather was particularly hot and humid. The Wright Research Center made an exception and took a summer vacation. One day, Fleming was in an extremely irritable mood. The consecutive failures over the past few days and the suffocating weather made him feel like doing nothing. He put down the experiment in his hand and prepared to go to the seaside to avoid the heat. The utensils on the experiment table were placed there in a mess. This was the first time in Fleming's 20-plus years of scientific research. At the beginning of the month, the weather gradually cooled down, and people's moods became more peaceful. Fleming returned to the laboratory where he had been away for many days. As soon as he entered the door, he habitually observed the petri dishes filled with culture fluid that were placed on the workbench before the holidays. Looking at the petri dishes that had already become moldy and hairy, he regretted not cleaning them up before the vacation. At this moment, a petri dish with clusters of green moldy flowers caught Fleming's attention. He picked up the contaminated petri dish and observed it carefully. His assistant was about to clean the petri dishes when he said,""Sir, the culture medium is moldy. I'll pour it away.”"No, there seems to be an 'article' here.”Fleming walked to the window and looked at the light. He discovered a strange phenomenon. A circle of blank space appeared around the moldy flower. The originally thriving staph had disappeared. Fleming immediately realized, Could these staph bacteria have been killed by some kind of mold? He suppressed the surprise in his heart and hurriedly put the petri dish under the microscope to observe. Sure enough, it was confirmed that all the staph around the moldy flower had died. The meticulous scientist specially cultivated a lot of these green mold, and then dripped the filtered culture fluid into the staph. In the end, a miracle happened. Within a few hours, all the staph bacteria died. He then diluted the culture fluid 10 times, 100 times…until 800 times, and dripped it into the staph bacteria one by one to observe their sterilization effect. The results showed that they could kill all the staph bacteria. Further animal experiments showed that this mold was quite toxic to bacteria, but it had no effect on white blood cells, which meant that it was harmless to animals. After that, Fleming and his assistant published a paper on pinching on the basis of further experiments in June 1929 in the British journal Experimental Pathology. In the paper, he pointed out: " It has been shown that there is a kind of penicillin-type mold that secretes a substance with very powerful antiseptic ability. Not only could it kill Staph, but it could also kill many bacteria such as streptococci.”Unfortunately, Fleming was not a physicist. There were too few active ingredients in the culture fluid, and he had never been able to solve the problem of purifying the Penicilin. Coupled with the global popularity of sulfuric acid drugs at that time, penicillins did not attract much attention. However, Fleming believed that one day, Penicilin would benefit mankind. He carefully preserved the strain and cultivated it generation after generation.
