Episode 157 Free Lecture on Medicine (2)
Almost as soon as he runs out of words, the professors and students finish preparing to take notes.
The atmosphere in the auditorium, which had been cluttered, quickly changed.
Ray looked around, took a moment, then opened his mouth.
“Today’s lecture is ‘Practical first aid and understanding of microorganisms’.”
He spoke in silence to those who would listen.
“In the war, we watched the performance of the priests right in front of our eyes. However, it is not only priests who can save people who are on the verge of death.”
Currently, he is a professor and at the same time a saint chosen by God.
However, when the saint said that priests are not the only ones who can save people, it is ironic.
At his words, most of them gave a puzzled expression.
“Some of you may have already experienced or witnessed it on the battlefield, but there are definitely diseases that priests and priests and even us adults cannot cure.”
“Even adults can’t fix it…”
“Then I have no choice but to assume he’s already dead…”
He finished his speech before the buzz grew louder.
“But it’s not something that can’t be cured if treated in other ways. The Medical Academy, which accepts students from today, will focus on the treatment of diseases and traumas that priests have not been able to cure.”
Even if you say it for a long time, in the end, it is the sound of ‘if you are interested, go to school.’
Certainly, in their lives, they have often seen diseases that priests and priests could not cure.
Even if it is divine magic, it is not omnipotent. Obviously, there are things that cannot be fixed.
For example, there is an allergy that was treated in the Principality of Silos.
Before entering the lecture, he expressed his aspirations and wrote something down on the blackboard.
It was the basic definition of traumatic sepsis for the abrasions and trauma that took so many soldiers’ lives during the war.
Of course, there is no such thing as justice in another world.
Facing them with questionable eyes, Ray knocked on the podium twice.
Tak-Tak-
“We will now refer to all external wounds by the word ‘trauma’.”
There was no disagreement with what he said. The professor giving the lecture said he would, so there was no way he would object.
“Then, before going into the main lecture, let’s talk about why soldiers who could be saved during the war died even with minor trauma.”
Some of the students in the front row who received Ray’s glance immediately responded.
It was so fast that he didn’t seem to worry too much.
“It’s because there weren’t enough priests or priests to treat a soldier with such minor injuries.”
He answered in an instant, but he calmly answered as if he were teaching.
“Half right. But why did the soldiers die when there was clearly no trauma that would result in death?”
“….”
No one answered his nonsense-like words with the same speed as before.
Ray, who waited for a while for someone to answer, finally opened his mouth when everyone was silent.
“The answer is this traumatic sepsis.”
As I underlined the words on the board, they became interested.
“There are many microbes living around us that we cannot see with the naked eye. For example, even in the palm of the student who answered earlier.”
I explained it in an easy-to-understand way, but I couldn’t understand it even if I said it suddenly.
One of the professors listening to the lecture asked a question.
“Are you saying that microbes… live everywhere and on everything?”
“that’s right.”
“But right now, I don’t feel anything around me…”
Hearing his words, Ray was full of energy.
Could it be that he wanted to feel it as mana?
No matter how knowledgeable I was, I couldn’t answer right away because it was such an embarrassing remark.
Yeasts and molds are classified as eukaryotic microorganisms.
For example, the professor in front of me said that he released mana to feel the presence of microorganisms in the fungus.
It’s ridiculous. If I could feel that, that professor would already be stronger than Aira.
“Microorganisms are too small to be seen with the naked eye. It’s impossible to feel that way.”
It is truly far away to feel the size of 0.1mm or less beyond the visual limit of the naked eye.
Questions flooded in from various places to see if the explanation was not satisfactory.
“What the hell is that microbe? How do you know them?”
“I want you to show me the proof.”
“Evidence…”
He pondered for a moment, then brought out an example.
“I believe that everyone knows how bread changes after being left at room temperature for a long time.”
“It will rot.”
“That’s right, it rots. But it doesn’t just rot, it grows mold. Do you understand if I say that this fungus is also a microorganism?”
“….”
“….”
Seeing that nothing was said, it seemed that he did not understand.
It seems better to explain the reason for mold growth.
“…microorganisms each have their own unique properties. If we divide the names by nature, we call them algae, bacteria, protozoa, fungi, and yeast. . The decay of the body is also due to the decomposition of microorganisms.”
“You mean that plague?”
Some people even jumped to their feet when they said that microbes were everywhere and that infectious diseases were caused by them.
A feeling of unexplained discomfort was felt in the part of the body that was in contact with the chair or desk.
Ray wrote on the blackboard again.
Harmful microorganisms that cause food poisoning by self-producing toxins of pathogenic microorganisms that cause diseases in animals and plants and cause deterioration or decay of various substances related to food, clothing, and shelter.
He explained the characteristics of each of the roughly selected fungi.
Microbes are not necessarily bad.
Antibiotics, such as penicillin, made by Ray in the Grencia Mountains, are produced by green mold.
Because I was ignorant, I was only harmed by microorganisms, but if I knew it, it would be a different story.
If these could be used well, they could be greatly used to produce useful substances with microorganisms like in modern times.
“Returning to this topic, when trauma is infected with microorganisms, it causes a severe inflammatory reaction, which can be called sepsis. If not treated in time, the mortality rate is ridiculously high. This is why soldiers died from relatively minor wounds during the war.”
“…So… you mean you could die if you just fell off the floor?”
Ray pondered for a moment at a female student’s question, then nodded.
It’s a story that can happen to some extent here, not knowing in modern times.
Hygiene itself is not very good, so if the wound is big when you fall, there is a chance that you will get sepsis.
“I could die.”
“…”
This is scary, so I’m looking at the world.
Originally, in order to treat or prevent sepsis, it must be treated with appropriate antibiotics.
He could rely on priests or priests, but that was only when they were right next to him.
What’s the point of calling me when you’re not by my side?
In the end, what helps in the end is knowledge.
However, there is no need to fear sepsis any more than necessary.
The body tissues and blood have a certain amount of defense against external stimuli, pathogens, and things that harm the body.
So just because a pathogen invades doesn’t mean you get sick right away.
Since they are people from another world who have higher average defense than people in modern times, you probably don’t have to worry about that.
In the case of war, however, it is different.
Ray, who added basic explanations, intended to teach them ‘first aid’ based on them.
Ray made eye contact with those around him and spoke calmly.
“What would you do if you were wounded during the war? Would you give up your life because you’re afraid of traumatic sepsis? Would you like to cut the flesh?”
“….”
The story, which seemed quite tough at first glance, made them unable to answer.
One answer is, of course, fixed.
Because no one wants to give up their life or their body.
“In the case of light trauma, simply washing the wound thoroughly with clean water is effective. In order to prevent infections such as sepsis, all activities that kill microorganisms will be referred to as ‘disinfection’ from now on. If sufficient disinfection is done at the trauma site, there is no need to worry about sepsis.”
“…”
“Did you understand?”
“…I’m sorry, but I still can’t feel it.”
It will.
I didn’t even know the existence of microbes until now, but I can’t accept all the information at once.
“If you’ve ever been caught in a cleg here, raise your hand.”
Clegg. It’s like a cold, so to speak.
The common cold is caused by more than 200 different types of viruses.
About 30-50% of these are rhinoviruses and 10-15% are coronaviruses.
Similar viruses to the rhinovirus that cause cold syndrome are not unique to modern times.
There was something similar in another world, but it is called Clegre here.
Most of the professors and students raised their hands at Ray’s words.
If there were people who didn’t, it was only those from the Chepes family.
The majesty of the Duke’s family is so great that it transcends imagination.
Perhaps they didn’t even recognize that they had Clegg and were cured by the priest.
He himself had been caught in clegs when he was young. Although he was well treated by his mother, Sein.
“Everyone knows that if you get Clegg the wrong way, you can die.”
“Couldn’t you, Professor, be saying that Clegg is also caused by something called microbes?”
“Not exactly. I can’t say there’s no influence at all, but Clegg is mainly caused by something else. There’s really no end to explaining this, so I’ll explain it in a slightly simpler way.”
Ray cast a spell on a small barrel placed at the bottom of the podium.
“Water.”
As his mana moved with a small resonant sound, the barrel was soon filled with water.
Ray washed his hands there casually.
“When you wash your hands like this, the microorganisms in your hands are not completely disinfected. But that doesn’t mean it doesn’t work.”
As his mana became cold, the water gradually grew colder.
The people filling the auditorium unknowingly immersed themselves in his lecture.
