In the medical hall, Ma Qiang put on the mask that Lu Qingling helped you urgently sew last night, although it was linen, it was better than nothing.

"Ma Lang, what is this?" Li Jue looked at Ma Qiang wearing a mask and asked curiously.

Ma Qiang took off the mask and said, "This is called a mask, it is a kind of medical protective equipment, you see, many patients have viruses and bacteria in their body fluids... You can understand that it contains toxins, and if people come into contact with the body fluids of these patients in places such as the mouth and nose, it is easy to be infected, but with this mask, it can have the effect of isolation.

Although it can't completely isolate these toxins, it's much better than wearing nothing at all. ”

Li Jue thought about it, clapped his hands and applauded, "But that's the case, in fact, my master also asked us to cover our mouths and noses during the pandemic, but we all use cloth towels, how convenient is it without you." ”

This is Ma Qiang was frightened, I didn't expect that someone in the Eastern Han Dynasty would discover these problems, but unfortunately, for various reasons, too many essences of traditional Chinese medicine have not been passed down or have not been summarized by people for various reasons.

"Come, County Lieutenant Zhang Sheng, you fiddle with your head with my hand, Brother Xianyu, you help shoot the reflection of the bronze mirror into his mouth."

Since there is no such thing as a flashlight, the observation of the oral cavity can only rely on sunlight and a bronze mirror, although the effect is poor, but it is still the same sentence, better than nothing.

"Doctor Li, come and see, here, and here, are they not the same as ordinary people's teeth?"

Ma Qiang used a small wooden stick to gently point to the location of the dental calculus in Zhang Sheng's mouth.

"Yes, what is this?"

"This is one of the reasons for his bad breath, this thing is called dental calculus, which is the product of people who have not cleaned up their mouths for many years, and then you look inside, this circle of yellow-white things, this is tonsil stones, which is the main cause of bad breath, many people have it, but few people have it."

Ma Qiang admired Li Jue a little, and he couldn't bear Zhang Sheng's bad breath without wearing a mask.

But what Ma Qiang admires even more is Zhang Sheng, where is this called tonsils, this dense stone is inlaid on it, not so much that this thing is called tonsils, it is better to call him the right point of corn.

"What are stones?" Li Jue asked with some confusion.

Ma Qiang thought for a while and said, "Stones are dirt that accumulates somewhere in the human body due to various reasons, and stones are most likely to grow in the liver, gall bladder, kidneys and other parts of the internal organs, as well as the roots and tonsils in the mouth.

Most of the bad breath is caused by dental calculus and tonsil calculus, and some people have gastrointestinal problems, but I also asked Zhang County Lieutenant before, he can be said to eat Ma Ma Xiang, his body is great, and there is no problem with the stomach at all, right? ”

Zhang Sheng nodded hurriedly, indicating that Ma Qiang was right.

"And what about these stones?" Li Jue continued to ask.

"It's easy, just get it out." Ma Qiang began to prepare the equipment.

The way to deal with stones is so simple, crude and boring.

"Get it out?" Li Jue's eyes lit up, "Could it be that Ma Lang, you also know the art of disemboweling?" ”

I'm a scientist, not a doctor! Ma Qiang couldn't help but vomit in his heart.

Because Ma Qiang has studied and exchanged in Europe and the United States for a long time, and Europe and the United States attach great importance to dentistry, he has also been exposed to a lot of dentist knowledge, but for other medicine, he really only knows some basic common sense, which absolutely cannot support him to do surgery.

"I'm not going to... Wait a minute.. Also.. Dr. Lee, would you? ”

Ma Qiang is looking forward to it, this Li Jue is Hua Tuo's apprentice, and Hua Tuo's most famous surgery in medicine is not his surgery.

"It's my mentor's club, and I want to learn too, but my mentor said that I wasn't talented enough and didn't pass it on to me."

Ma Qiang couldn't help but roll his eyes, this damn gateway opinion.

It is also said that although Hua Tuo was killed by Cao Cao in the end, Hua Tuo has disciples, whether it is this Li Jue or several other disciples, they are alive and well, but Hua Tuo's surgical skills and Ma Boiling are still lost, and the only explanation is that Hua Tuo did not teach them to any disciples.

But thinking about it again, in terms of the understanding of bacteria in this era, Ma Qiang is also very suspicious that these apprentices will not be able to perform a few successful surgeries even if they can do it after Hua Tuo.

This is an era when even tooth extraction can cause infection and death.

"I heard that Mr. Hua has a medicine called Ma Boiling Powder, which can make people unconscious, is it true? Touching the tonsils can easily make people want to vomit, and it is best to make him faint. ”

Ma Qiang said that he suddenly felt that what he was talking about was not numb, but more like Wu Yong's favorite sweat medicine, etc., and so on.

"There is indeed this medicine, the teacher has studied for many years to make this medicine, its effect can indeed make people unconscious, the teacher said that this thing is used correctly, and the use of evil is evil, and it cannot be easily outflowed, and it also needs a strange flower in the Western Regions, which is extremely precious, so I don't have this thing here."

Li Jue's words made Ma Qiang sure that this hemp boiling powder really used the kind of flower where evil and beauty coexist.

"Then there is no way, Brother Xianyu, come on."

Ma Qiang shrugged helplessly and motioned for Xian Yu to help.

"Oh? It turns out that my brother will be numb..."

"I'll fight!" Xian Yufu punched Zhang Sheng in the back of the head, and Zhang Sheng fell to the ground with a thud.

"Well, it works well, I'm dizzy." Ma Qiang kicked Zhang Sheng, seeing that Zhang Sheng didn't react at all, he expressed his appreciation for Xian Yufu's strength.

Li Jue's open-mouthed boss, teacher... Your hemp boils as if... There's no need to exist anymore.

"Come, help open his mouth, sackcloth, stuff it in, so that his mouth can't close, yes! Bronze mirror, quick! The light is good, the iron skewer... I said Qingcheng, didn't I let you tie the burlap in front? You're trying to stab him to death. ”

This may be the first surgery in history to remove dental and tonsil stones.

It is also probably the most violent operation in history.

When the first tonsil stone was squeezed out by Ma Qiang, everyone wanted to vomit, and the taste was a hundred times more powerful than in Zhang Sheng's mouth.

Ma Qiang also felt that it was difficult to breathe, and this temporary mask didn't seem to be very effective....

Forget it, for the promotion of toothpaste, fight!

Tonsil stones can come out as long as they are squeezed, but dental calculus is very strong and must be pried, Ma Qiang's skills are not very good, anyway, after doing it, Zhang Sheng is already a mouthful of blood.

"Okay, can you get him to wake up soon?" Ma Qiang put the various stones scraped out on the linen cloth on the side, and then asked Li Jue.

"No problem, I'll come."

Li Jue is also very excited, this time he has learned a lot of things, whether it is the cognition of stones or the cause of bad breath, he can have a good exchange with Master in the future.

What Master said is indeed right, you have to travel around to get the best of all families.

I don't know where Li Jue pinched Zhang Sheng, anyway, Zhang Sheng immediately woke up slowly.

"Awake? Come on, rinse your mouth. ”

Ma Qiang motioned to the boy to hand Zhang Sheng a glass of water, and Zhang Sheng took it while touching the back of his head, and spit out the blood and some broken stones with a hula.

"It's... What's wrong with me? ”

Zhang Sheng was still a little confused, looking at the blood he vomited a little foggy.

"It's nothing, scraping stones will inevitably cause a small injury."

Ma Qiang's face did not change and he was talking nonsense.
