[Henan Science Science] Western Medical Story: The "Green Legion" flying in the air

Science is a sharp sword. People can use it to cut thorns to create happiness. At the time of World War II, 51.2 million people in the world were killed. Science has created the most powerful murder weapon for this war, atomic bombs, and science also discovered a magic weapon to save people at this time -penicillin.

Alexander Fleming (1881 ~ 1955) was born in Rockefield, Britain. After graduating from the medical school, he went to San Mary Hospital for internship and became a researcher at the bacterial department of the hospital.

Shortly after Fryming took office, he caught up with the outbreak of the First World War. The pain of the frontline soldiers' wound ulceration infection left a deep impression on him. He vowed to solve this problem. In 1928, he concentrated on his strength to study Pugioe.

Staphylococcus aureus is the root of wound ulcers, pus and pus, and blood poisoning. The research method is to inoculate this bacteria on the dine, give it a little culture liquid to let it grow, and observe its form and growth law.

One morning, Fleming came to the laboratory and found that there was a pylori on a diner half less than yesterday. This is what is often in the laboratory, but when he is going to pour the polluted dine, a idea suddenly appears in his mind: what a hate bacteria pollutes my diner? Intersection

It was Fleming's thought that made thousands of life see hope.

Fleming found that the spores of some threaded molds from where they did not know where to fly from the diner, which grew a layer of green mold, and this green bacteria were very powerful, and the yellow bacteria slowly slowly slowed down. Devouring!

Under the microscope, Fleming found that these green molds were very beautiful. At first, a little white fluff was grown, and later it became a layer of green "carpet", and each one was like a brush immersed in the water, on his head, his head, his head, and his head, his head, and his head, with his head, his head, his head, and his head, with his head, his head, and his head, with his head, his head. There are also brushes that are opened to the surroundings.

Fleming was very excited. He judged that this new bacteria is likely to be a dead enemy of Pugacer. It is not just a nutrients with bacteria, but also secreted a kind of juice to kill the other party directly! So Fleming ordered the assistant to carefully filter the mold culture liquid, and then drip a drop of filtering liquid into a small dish full of bacteria. After a few hours, the abominable bacteria disappeared without a trace.

For the treasure, he diluted the filtration fluid to various concentrations and tested it in various bacteria. When the concentration is 1, it is enough to kill the chain -shaped bacteria; by 1/300, the reproduction of grape bacteria may be prevented; by 1/800, pneumococcal bacteria can be killed.

This is really a great event from the sky. Those crazy germs, originally had the same small gadgets as it were to deal with it easily. Bacteria can be confronted by other bacteria, which is antibacterial.

As a result, Fleming named the first antibacterin discovered by humans to penicillin.

Penthicin small knowledge

Penicillin (Penicillin, or phonetic translation of Nicolin) is also known as penicillin G, penicillin sodium, sodium penicillin sodium, penicillin potassium, and chilinoin potassium. Prillcin is a type of antibiotic. It is a type of antibiotics that can destroy the cell wall that can destroy bacteria and sterilize the bacterial cells during the reproductive period of bacterial cells. Penicillin is a very common antibacterial drug. It has good quality and low price, but it must be performed before each use to prevent allergies.

The allergic reactions of penicillin are manifestations of medicinal heat, medicine rash, and vascular neurological edema, which is seriously allergic shock. Allergic shocks are usually found within a few seconds to five minutes after injection. Only a few occurred in more than 30 minutes, so it must be observed for 30 minutes after clinical medication. Patients show cold sweat, cold limbs, difficulty breathing, dyskillers, lower blood pressure, and coma. If they are not rescued in time, they can endanger life. It has nothing to do with dosage.
