If the medication in the initial stage cannot be used, then the medication in the oliguric stage is mannitol.

Scientific experiments are actually constant trial and error. If you find that something doesn't work, give up immediately and try another idea. This is the rationality a scientist should have.

"The molecular formula of mannitol is C6H14O6, etc... I remember there is something that naturally produces this substance."

Ma Qiang remembered it, it was kelp.

The white frost on the kelp is mannitol!

Of these two medicines, one is really complicated and the other is simple.

Not to mention sodium bicarbonate, it is baking soda, which can be obtained by carbonizing carbon dioxide in sodium carbonate and then separating and drying it.

As for sodium carbonate, it can be obtained by adding Glauber's salt, limestone and coal to reduce and carbonate it at high temperatures, and then through leaching, evaporation, refining, recrystallization and drying.

This is not complicated. France began to use this method to obtain soda ash at the end of the 18th century.

As for the more convenient Hou's alkali production method, ammonia gas is needed, and the production and storage of ammonia gas are not possible under the existing conditions.

Ma Qiang thought for a while, summarized the treatment methods for this disease, then turned off the phone and put it away, and opened the door.

Xian Yufu, who was standing guard outside, saw Ma Qiang coming out and looked at him expectantly. Ma Qiang nodded and said, "Immediately summon all the doctors, officials, and the children of the aristocratic families as agreed before. I will give them a gift in the morning two days later."

Attend class!"

"No!" Xian Yufu responded loudly.

Xian Yufu was very familiar with Ma Qiang's smiling face, which was a sign that Ma Qiang was confident about something.

Ma Qiang came to Tian Liang again, raised his hands and said, "Tian County Cheng, please summon some of the best jewelers, carpenters, and blacksmiths. I need to make something."

Although Tian Liang was a little confused, he still agreed.

Ma Qiang squinted his eyes. The syringe can be made of wood or metal. The key is the needle. I hope the skilled craftsmen of the Eastern Han Dynasty can solve this problem.

——Two days later

Dozens of doctors sat in a room, whispering anxiously to each other non-stop.

"I heard that the newly arrived county magistrate will give us lessons? Does he know medical skills?"

"Mr. Ma is said to be a disciple of an immortal, but I don't know whether it is true or not."

"Now more and more patients from all over the country are transported to the isolation area. Yesterday, hundreds of people were transported from various villages. We are all here, what should we do there?"

"There is nothing we can do even if we are there. Even Dr. Li can't prescribe a prescription. What can we do?"

Many people looked at Li Xun, who was sitting in the front. Li Xun kept tugging on his beard with his eyes closed. Who was under the most pressure these days? It had been him for a long time.

He is the best doctor in Jixian and even Youzhou, but he has nothing to do about the current black plague except to relieve the patient's condition. You can imagine the anxiety in his heart.

"coming!"

Li Yan opened his eyes and saw a group of officials headed by Tian Liang, and children from aristocratic families came in. Everyone sat down in the back or middle aisle with cushions.

Ma Qiang directed the sergeant to hang up the blackboard.

Ma Qiang looked down and saw that there were almost everyone there, so he said, "Dear doctors, colleagues, and gentlemen, time is urgent. Let me make a long story short. After reading the secret book of my school, I already know the cause of this disease, and there are some

Now I’m telling you how to deal with it. Remember, if you have any questions, wait until I say you can ask them. If there are no questions, I’ll start.”

As he spoke, Ma Qiang took out the chalk and started writing on the blackboard.

"Dr. Li said this disease is called black plague, but in our school of thought there is a professional name called hemorrhagic fever with renal syndrome, which is a type of plague.

What is plague? Plague is an external evil called a virus that is spread through rats or similar animals. These rats carry this external evil in their bodies, and then spread it to people through water sources, food, etc., and people in turn spread it through spitting and sneezing.

, passing the virus to other people through urination and defecation.

The mortality rate of this disease is very high. According to records, it can reach 90% at its peak. It is an extremely terrible plague. Its onset characteristics can be summarized as three pains and three rednesses, namely headache, low back pain, orbital pain, face, and neck pain.

and upper chest redness, accompanied by nausea, vomiting, chest tightness and other symptoms.

The stages of its onset can be divided into fever stage, shock stage, oliguria stage, polyuria stage and recovery stage.

So to deal with this disease, we must first cut off the source and then treat the person! Okay, now you can raise your hand to ask a question."

Everyone understood what he meant by raising his hand, and in an instant a small forest appeared.

"Doctor Li, you should ask first."

"Sir, I have no doubts about the name. This disease does damage people's kidneys. But sir, he said that this disease is spread through rats. Is there any evidence?"

Ma Qiang thought for a moment and replied, "Our school has an instrument called a microscope, which can allow people to see this kind of external evil. However, I don't have it in my hand now. Please just take it for granted. I will find a way to make this thing in the future."

Solve the confusion of the world."

In fact, Chinese medicine has long ago used the term "exogenous evil" to briefly describe things like viruses and bacteria. However, because China has never invented a microscope, Chinese medicine cannot truly understand the true face of the plague, which is extremely regrettable.

"We also know that human saliva can transmit the plague, but how can it be transmitted through urine and feces? No one drinks other people's feces and urine, right?" A doctor asked the second question.

"This mode of transmission through defecation is called fecal-oral transmission in our school of thought. Indeed, no one will directly eat other people's feces and urine, but think about it, after a person defecates, there will be more or less dirt on his hands.

, if these dirt are not washed away in time, and then touch some places, such as doors and windows, and other people touch it, then this person's hands will be stained with this person's dirt. If this person eats or eats directly without washing his hands,

If there are wounds, the virus on these filth will cause this person to be infected with the plague."

"So that's it..."

"No wonder the county magistrate forces all patients to wash their hands and use soap after going to the toilet..."

Seeing that everyone understood, Ma Qiang continued, "In order to cut off the roots, County Magistrate Tian! Lieutenant Zhang!"

"Yes!" they both responded together.

"The two of you are responsible for the extermination of rats inside and outside the city respectively. I want there to be no more rats in this city, and there are no more rats in the villages outside the city. Especially in places where food is stored, there must be no rats. I know

This is difficult. Tell everyone that the county government is willing to exchange three times the same weight of grain for these rats! This is not only eradicating rats, but also saving lives!"

"promise!"

Tian Liang and Zhang Sheng accepted the offer together.

A group of aristocratic families have agreed to endorse the expenditures for this plague, and Ma Qiang is now spending money without mercy.

"Then I will tell you how to cure it. This disease is both difficult and easy to cure."

Everyone's eyes suddenly lit up. Is there any cure?

“Let’s talk about the onset of this disease first. After the onset of this disease, it can be divided into five stages, namely the fever stage, shock stage, oliguria stage, polyuria stage and recovery stage. These five stages must be dealt with separately...

"

Ma Qiang spoke carefully, and the officials and doctors below also remembered to be careful. Time passed slowly, and Ma Qiang was writing and erasing on the blackboard. People kept raising their hands to ask questions, and Ma Qiang also tried his best to answer them one by one, trying to make everyone happy.
