Chapter 61 This thing is called penicillin
Zhao Yi said: "Don't worry, I will answer your questions one by one."

When the doctors heard this, they quieted down and listened carefully.

“Although bacteria are small, they are living things just like us and can be killed.”

"The simplest method is high temperature. But high temperature will also kill cells in the human body and may still cause infection."

The doctors who were former military doctors suddenly discovered that the probability of wounded soldiers developing ulcers would be reduced if they burned their wounds with fire.

The original reason is here!
They accidentally killed the bacteria with high temperature.

Could it be that Zhao Yi is really an immortal?

Otherwise how would he know so much.

Zhao Yi continued to explain.

"Then there is also a type of cell in our body that can engulf and kill harmful bacteria. It is called a white blood cell and is usually found in the blood."

"The way white blood cells kill bacteria is by engulfing them, but they will die if they engulf too many bacteria."

"So when a wound becomes inflamed, a white film or pus often appears. Those are dead white blood cells."

The doctors then understood why the pus in the wounds was white and yellow.

It turns out that it is caused by dead white blood cells.

As expected, the medical knowledge that Zhao Yi possessed far exceeded their medical skills!

To be able to study ulcers to such a level!

Know the real cause of ulcers.

"If there aren't too many bacteria, the white blood cells can handle it. Then the sore will heal on its own. That's why sometimes sores go away on their own."

"But if there are too many bacteria, the white blood cells cannot process them. Then the bacteria will continue to multiply, causing the sores to continue to spread."

"In the end, the injured part of the patient's body gradually rotted, and finally endangered the patient's life."

"But it's just like what you said. There are things in the world that can kill bacteria without causing any harm to the human body."

“I named things that kill bacteria antibiotics.”

The people below were very curious when they heard about antibiotics.

There is actually such a thing in the world!

Zhao Yi took out a glass bottle filled with white powder.

The white powder was the penicillin he extracted during this period.

"The thing in my hand is what I just said can kill bacteria. Its name is penicillin. It is a type of antibiotic."

"It can kill most bacteria and restore your body to health!"

The doctors below were all staring at the bottle of penicillin in Zhao Yi's hand.

In their opinion, this is a miracle drug!

Because according to Zhao Yi, this thing can kill bacteria.

This means that penicillin can completely cure the ulcer.

You know, ulcers have always been a headache for them.

Their usual treatment of ulcers is essentially to nourish the patient's body and let the patient's body kill the bacteria and heal itself.

If the patient is not in good health, there is nothing they can do.

But now Zhao Yi showed them another result.

When Wang Jian Ying Zheng heard this, he realized where penicillin could play a greater role.

That is the battlefield!
If the Qin Dynasty had penicillin, then soldiers injured on the battlefield would no longer have to worry about wound infection and inflammation.

This will save the lives of most of the wounded soldiers.

You should know that most of the dead soldiers died from wound infection and inflammation, and the rest died from excessive bleeding.

Penicillin plus alcohol disinfection to prevent wound infection will suppress the death rate of wounded soldiers in Daqin to a very low level. In this way, Daqin will have more experienced battlefield veterans.

Zhao Yi continued, "It's almost like a panacea. Because it can cure more than just sores."

"It can cure any disease caused by bacteria!"

A doctor immediately asked a question.

"Teacher Zhao Yi, besides causing sores, what other diseases can bacteria cause?"

"That's a good question. There are many infections caused by bacteria."

"It's a sore on the skin, and in the throat it's laryngitis."

"Once the bacteria infect our nose, it will cause a cold, which is what you call a cold or a chill."

The people below were shocked to hear this.

It turns out that colds and chills are also related to bacteria!
This solves the problem that has puzzled doctors for a long time - what causes colds and chills?
They have been trying to figure out the reason for this.

But I still don't understand.

So we can only use the word "cold" to refer to it.

"If the infection continues to spread, the body will fight back, which will cause the body to heat up and burn the virus to death. At the same time, the white blood cells will kill the bacteria, so the patient will have phlegm and runny nose."

Zhao Yi's remarks shocked the doctors again.

It turns out that this is the reason why the patient has a fever.

It's the patient's body trying to kill the bacteria!

Zhao Yi continued, "If the body's counterattack fails, the bacteria will continue to spread inside the body and eventually reach the lungs. At this time, people usually cough continuously because the lungs are also inflamed due to the infection. That's why I call it pneumonia."

Zhao Yi's words made everyone below think about something.

According to Zhao Yi, when bacteria infect the lungs, people will cough continuously.

Isn’t this symptom of tuberculosis?

It turns out that tuberculosis is also caused by bacteria!
In this case, penicillin can also treat tuberculosis!
This is simply a miracle drug!
You have to know that they are basically helpless against tuberculosis.

In this era, once you get tuberculosis, it is basically a death sentence.

"Penicillin can treat colds, fevers, and pneumonia caused by bacteria."

When Ying Zheng and Wang Jian heard this, they were very happy.

It would be great if penicillin could cure so many diseases.

In this way, there wouldn't be so many people dying from these diseases every year in Daqin.

You should know that diseases such as colds, fevers, and pneumonia claim the lives of hundreds of thousands of people in the Qin Dynasty every year.

No wonder Zhao Yi called penicillin a panacea.

In fact, this is normal, because the average life expectancy in Daqin is over 20 years old.

Part of the reason is due to the level of medical care.

In this day and age, catching a cold can really be fatal.

Because the civilians were already malnourished due to frequent hunger.

Once such a weak body catches a cold, it is likely to develop a fever, followed by pneumonia, and finally death.

"And penicillin can treat wound infections. So that means we can do one thing - surgery."

"The so-called surgery is to use a knife to cut open the human body, and then remove the diseased tissue locally..."

Zhao Yi simply explained the concept of the operation to the people below.

Everyone was completely shocked after hearing this.

Is this a surgery? This is clearly a magic technique! They actually have to cut open a person's body!
