Magus Tech Chapter 354: Pneumonia and penicillin (popular science
Laboratory, main laboratory.
In the room, Pandora finished washing many test tubes and put them on the test tube rack, her eyes were shining brightly, full of pride. Stretch out a finger and point to the test tube.
"Ita!" A!
"Toke!" Two!
"Sarah!" Three!
"Spa!" Four!
"Wa..." Pandora blinked her eyes when she had just counted to the fifth, and felt that there was something dirty on the wall of the test tube that hadn't been cleaned. , ready to brush again.
At this moment, with a "bang", the door of the laboratory was knocked open, and Li Cha stumbled and walked in with an extremely pale face.
"Wow!"
The glass tube in her hand was directly crushed, Pandora turned around and looked at Li Cha in surprise.
At this time, Li Cha was wearing a thick mask, tightly covering his mouth and nose, and didn't say much at all, but said briefly to Pandora: "Pandora, you go to the courtyard and wait for me, I will tell you to come in and then come in. "
"Scared?"
"Hurry up." Li Cha breathed heavily and quickly under his hands, and finally took a deep breath, "Be obedient——"
Pandora frowned, her eyes flickered, and finally listened to Li Cha's words, and stepped out to the yard.
Li Cha immediately closed the door of the laboratory, closed and sealed all the doors, windows, entrances and exits, and sealed the entire laboratory.
After finishing all this, he took off his mask and began to take a big breath.
There is no way to do this, he couldn't help being careless. Generally speaking, the infectivity of pneumonia is very weak, but in the current world, some people are starting to use it as a weapon. Does anyone know if there are some mutations? He didn't want Pandora to give it a try.
It is true that Pandora has a great chance of being immune to the infection even if it is infected by virtue of the strong physique of the dragon clan, but if you can take the risk or not.
Thinking in this way, Li Cha calmed down and fully sensed the condition of his body. He found that the typical symptoms of pneumonia such as cough, fever, dyspnea, and chest pain were all there, and they became more and more severe. The most serious thing is fatigue, which is a common manifestation of pneumonia patients, with a probability of more than 90%, and even if it is cured, it will last for a long time.
At this moment, Li Cha felt as if his whole body was filled with lead, and it was difficult to move his fingers, so he really wanted to fall to the ground and fall asleep.
But he knew very well in his heart that this must not be the case. If he fell asleep now, he might never wake up. We must find a way to get rid of the pneumonia.
To solve pneumonia, we must figure out what is going on.
His pneumonia was caused by bacteria called mushroom spores. According to modern research on the earth, although it is relatively rare, it is not without related cases.
Actually, the most similar to his current situation should be the mushroom lung.
Mushroom lung is a lung disease that is extremely prone to occur to harvesters during the mushroom harvesting period on the modern earth. The physiological mechanism is that a large number of fungal spores invade the respiratory system and cause a series of pathological changes. The incubation period of this disease varies. If it is long, it can be extended to three months. If it is short, it can be done in 30 minutes.
Once it occurs, symptoms such as severe cough, sputum, chest pain, chest tightness, and shortness of breath will appear, accompanied by systemic symptoms such as headache, dizziness, palpitation, muscle soreness, heat, nausea, vomiting, loss of appetite, and digestive tract symptoms. symptom.
Compared with mushroom lung, the difference is: mushroom lung is an allergic reaction, and it will return to normal after being out of contact; he is more severe pneumonia, without effective targeted treatment, it will only get worse .
How to treat it?
Li Cha scanned the many wooden shelves in the laboratory, looking at the many materials on the wooden shelves, his eyes flickered.
For diseases caused by germs, the most effective treatment is of course antibacterial drugs, which is basically the common sense of all modern earthlings.
On the modern earth, antibacterial drugs are widely used, and even abused, leading to the generation of highly resistant bacteria.
In the wizarding world similar to the Middle Ages, there is no such concern—all germs have not been tested by antibacterial drugs. Compared with the germ companions on the modern earth, they are noobs among noobs.
If it is said that germs invade the human body, it is equivalent to robbers swaggering into an unguarded village. The antibacterial drug against germs is a long-tested, pioneering battle lion. On the way back, when I was bored, I wiped out a group of robbers who looked like thieves. I have never used antibacterial drugs In the world of drugs, the effect of using antibacterial drugs for the first time is almost a 12o% bonus.
One question now is, where do you get the antimicrobials?
The preparation of antibacterial drugs is simple and easy, but also difficult.
To put it simply, as common sense, everyone on the modern planet understands that the most commonly used antibiotic is penicillin.
Difficult point, how did you get penicillin in the first place?
If we start from the beginning, we need to push the time to... the summer of 1928 on modern Earth in July. The careless British scientist Fleming cultivated a large number of Staphylococcus aureus in the laboratory in order to write a thesis on staphylococcus.
During the cultivation process, Fleming forgot while cultivating. He didn't even cover the petri dish, so he went to the countryside for vacation. It wasn't until I returned from vacation in September that I remembered the matter of training. When I returned to the laboratory, I saw a piece of mold growing in the corner of the petri dish, and the Staphylococcus aureus near the mold was completely dead.
Fleming may be careless, but his sensitivity is not bad. He immediately conducted many experiments and studies, and finally determined that the mold grown in the petri dish can secrete special substances, which can kill a variety of pathogenic bacteria . He excitedly named the mold "Penicillium" and the secreted substance "Penicillin" while writing the paper.
Wait until the paper was on the table in England, it was already February 13, 1929.
Is this the end of the story?
Obviously not, for the penicillin exhibition, it is just the beginning.
It is true that Fleming was extremely lucky to discover the Penicillium fungus that had existed in nature for a long time, but how to purify it was a problem, and it could not be used for clinical treatment at all.
It was not until 1938 that the team led by Chain, Florey, and Heatley of Oxford University successfully extracted penicillin—this is already 10 years after penicillin was discovered. years later.
Extracted, the story is still not over, because the original Penicillium produced too little penicillin.
The penicillin production achieved by Fleming's laboratory is only 4 units per milliliter, or even lower. Only one month of continuous production can barely supply a patient~IndoMTL.com~After a lot of hard work , a research team in the United States designed a corn steep liquor culture solution, which increased the production of penicillin by ten times-4o units per milliliter, which is still not available to ordinary people.
Later, researcher Mary Hunter found a moldy cantaloupe covered with Penicillium in the Peoria market in Illinois, USA. She used this cantaloupe to screen and cultivate for many times, and finally the production of penicillin reached 250 units per milliliter. Researchers at the University of Wisconsin irradiated the strain with ultraviolet light to mutate it, increasing the production to 2,5oo units per milliliter.
25oo units per milliliter! This is already the limit of an era.
How many units of penicillin does a person need for normal treatment?
According to the modern treatment methods on the earth, even for common infections, 9.6 million units of penicillin are injected a day.
9.6 million!
9, 6oo, ooo, compared to 2, 5oo!
384o times!
It is completely conceivable how big the gap is.
In fact, it was not until Penicillium appeared for a long time, after countless strain improvements, that the production of penicillin was increased to 5000 units per milliliter, before it could be commercially produced and used on a large scale. Before commercial production and large-scale use, penicillin was more expensive than gold, really not a joke.
That's the problem!
Li Cha squinted.
If he wants to be treated with penicillin, even if he is extremely lucky and can get the natural penicillium vaccine in an instant, he will have to wait at least a month before trying to treat himself. To be realistic, it might be a year before getting enough penicillin.
By then, the body should be completely cool.
Well, it's getting colder.
