Chapter 217 Miracle
Late at night, behind the school palace, in the glass greenhouse.
Li Ang put a large bucket of penicillin suspension into the refrigerator, "Now, just wait."
On the table in front of him, there are more than a hundred ceramic petri dishes, which contain agar, staph bacteria extracted from syphilis patients, and a small piece of paper soaked in penicillin solution.
If all goes well, the paper soaked in the penicillin solution kills the surrounding Staphylococci, forming a circle in the Petri dish.
"call"
Qiu Feng, who was also wearing a white coat, let out a long breath and rubbed his tired eyes.
"A cup of tea?"
Li Ang released his mind power with a palm move, causing the thermos bottle placed in the corner of the greenhouse to levitate, and poured two cups of hot tea.
"Thanks."
Qiu Feng took the teacup, and the two of them leaned against the table next to each other, took a sip of tea together, stared at the petri dish in front of them, and remained silent.
Long hours of hard work are all pinned on the ceramic plates at this moment.
Zi'er wow, wow, wow—
The insects in the forest in the back mountain were still shouting vigorously, and from time to time there were one or two night owls chirping.
"That's right, Sunrise."
Qiu Feng spoke first and broke the silence. The joint struggle during this period has made the relationship between the two of them a lot more harmonious. .
"Is there any difference between this penicillin and allicin?"
"Well"
Li Ang thought for a while. The antibacterial principle of allicin is that the oxygen atom in the allicin molecule can combine with the sulfhydryl group in the cysteine molecule that is necessary for the growth and reproduction of bacteria, thereby inhibiting the growth and reproduction of bacteria.
Penicillin contains penicillane, which can destroy the cell wall of bacteria and play a bactericidal role in the reproduction period of bacterial cells, and has a miraculous effect on Gram-positive bacteria.
"It should be said that allicin is not easy to store and transport. The powdered penicillin can be stored for a longer time."
Li Ang explained: "Most of the allicin produced by the state capitals is used on the people in the state capitals, and cannot be transported in large quantities to other places as bulk commodities.
There are still many relatively remote places with inconvenient transportation. When allicin is transported there, it has lost its medicinal effect.
Patients who want to take medicine must go to the capital city in person.
Penicillin is more convenient to store and transport. "
"Is it?"
Qiu Feng's eyes lit up, the benefits of allicin are obvious, in Chang'an alone, the child mortality rate has dropped by more than 70% this year, and the maternal mortality rate has dropped by 75%.
For patients with blood carbuncle and other symptoms, the mortality rate has dropped by more than 80%.
If penicillin can be spread to all parts of Yu State, the average life expectancy of the people in Yu State can be increased by at least ten years, or even more!
The so-called hanging pot to help the world is nothing more than that.
Qiu Feng took another sip of tea, feeling uncontrollable excitement in his heart, subconsciously glanced at the young man beside him who had created this miracle, but found that there was not much smile on Li Ang's face.
Drug resistance
When the alien penicillin first appeared, dozens of units of penicillin could save lives. Pneumonia, puerperal fever, bacteremia, etc. were no longer incurable diseases, and the average life expectancy of the world soared.
For the first time in tens of thousands of years, human beings have successfully resisted the **** of microorganisms,
Use wisdom, hard work, and unity to conquer the invisible enemy.
But bacteria are also evolving and adapting.
Bacteria from generation to generation, or produce raw β-lactamases to hydrolyze and inactivate penicillins,
Either the penicillin-binding protein, the target of penicillin in vivo, changes, or the penicillin permeability decreases.
The effective dose of penicillin has gradually changed from tens of units to hundreds of thousands or millions of units.
Even vancomycin, known as the "last line of defense for mankind", has become precarious in the face of constantly iterative bacteria.
The number of deaths caused by antibiotic resistance in modern alien worlds is 1.27 million people every year!
another 4.97 million deaths were associated with it.
By comparison, AIDS and malaria kill 680,000 and 620,000 people each year.
And here, Li Ang is the only one.
These penicillins can be said to have been produced by him, countless years in advance, and crossing countless thresholds.
If he dies early, or because of external factors, it is impossible to establish a modern medical system and cultivate medical talents.
As a result, it will be completely out of control.
I am saving people, or killing people?
Li Ang let out a long breath, and the burden on his shoulders seemed to be heavier than ever.
The torrent of the times came much faster than he imagined, and the time seemed to be completely insufficient compared with what he had to do.
He turned his head, saw the worried expression on Qiu Feng's face, and smiled slightly, "It's okay, I'm just thinking about the patient.
correct,"
He changed the subject and said, "Your family doesn't seem to come to see you much recently?"
"They,"
Qiu Feng pouted, "They are studying the microscope, and the family quarrels every day."
Li Ang raised his eyebrows, "Arguing?"
"Because of medical matters."
Qiu Feng explained: "Many Science members have got microscopes to observe everything around them.
A bachelor was the first to use clothing dyes to impregnate tiny, moving round insects to better observe them.
And imitating Sunrise you, call those worms cells.
fine, subtle also. Describe the size of the worm.
cell, child birth package also. It is described that the body of the worm has a layer of membrane, which is like the coating of the fetus.
After that, many scholars discovered that there are many kinds of cells with different traits.
Some cells will not die when they meet water, but they will die when they meet hot water, they will die when they meet pure wine, and they will die when they meet allicin.
They made a lot of lists, guessing that these special cells are somehow the cause of people's illness.
Boiling water, washing hands with pure alcohol, taking allicin and other behaviors can kill disease-causing cells, so people will not get sick. "
Qiu Feng took a sip of tea and continued: "If this discovery is true, then the medical techniques and medical books we use now will undergo earth-shaking changes.
My family is arguing about this.
Whether it should be supported or opposed.
Should we explore a new direction, or follow the original medical principles. "
"Is that so"
Li Ang scratched his head. Although he also came from a family of traditional doctors, he is more familiar with the medicine in the memory of another world. "What do you think?"
"I?"
Qiu Feng tilted his head and thought for a moment, then slowly said: "I think, no matter which road it is, as long as it can cure the patient, it will be effective.
As for the longer-term, what is the dispute of orthodoxy, the dispute of ideas, the dispute of sects,
Get out of the way before the real suffering of the sick. "
"Do you want to see the curative effect without watching the advertisement?"
Li Ang smiled. If everyone in the world can think like Qiu Feng, then he will have a lot less trouble in establishing an alien medical system in the future.
The two leaned against the table, chatting with teacups in their hands. From the delicious food in Chang'an City, to where to go for the next winter vacation.
Li Ang is no longer the founding magistrate, and Qiu Feng is no longer the daughter of an imperial doctor.
They are just two doctors waiting for the medicine to come out, ready to help patients.
dangdangdangdang—
On the table next to it, the exquisite clock and watch sent by Su Feng made a crisp sound, interrupting their chat.
Time is up.
Li Ang put down the teacup in silence, stepped forward, and came to the table.
He and Qiu Feng looked at each other, and they picked up a petri dish together, and slowly lifted the ceramic cover.
