The daily routine of the ancient imperial examination

The two laughed and rolled and played on the grass. Anyway, there was no one else in the huge yard except them.

Lu Xiuyuan took advantage of the superiority to push the person down. After controlling the opponent's hands, he stretched out his evil claws and began to scratch the young master.

Even a strong man couldn't hold back the itchy flesh at that place, Shi Yunchen was only lightly poked a few times, and tears almost came out of laughter.

"Hahahaha! Two, Erlang, please let me go... I was wrong..."

Seeing that the other party was very itchy, he smiled maliciously, and took the opportunity to propose N friendly treaties for harmonious coexistence in bed.

The young master under him didn't hear everything, and nodded repeatedly: "Okay, okay, I agree."

Thinking of the happy life tonight, Lu Xiuyuan let the other party go with satisfaction.

After the first phase of penicillin research was completed, he had nothing else to do in the next seven days other than go to the blacksmith to pick up the custom-made utensils. Naturally, he had to find something to do for himself.

The two got up from the ground stickily. After the play just now, their bodies were covered with grass clippings. He reached out to help pick off the grass clippings from each other's heads, and then went back to the yard for dinner together.

Seven days passed in a blink of an eye. Early in the morning, Lu Xiuyuan took a cage of mice to the backyard to check the results.

When he came to the place where the petri dish was placed, he first checked the effect of the 8 bottles poured out of the No. [-] separation column.

Except for the vigorous growth of staphylococci on No. 8 that flowed out at the end, the cocci on other petri dishes avoided the place where the penicillin culture solution was instilled before, which shows that the fungi in the No. [-] separation column are useful!

The remaining nine separation columns were also checked, and there were many ineffective cocci on the petri dish, and the further the separation column was, the more penicillin was ineffective.

It is not ruled out that in a large amount of liquid, Penicillium is collectively distributed in the middle and lower layers, but this problem is not a big deal, and it will not affect it after purification in the later stage.

He was not the only one who came to test the results today, and the young master was also called to help by him. If penicillin that can be used by humans is really detected this time, then there is no need to worry about the candidate of steamed buns. It is the business to concentrate on cultivating penicillin for human use.

Shi Yunchen looked at the eighty petri dishes in front of him, not quite understanding what they meant.

"Erlang, is this a success?"

Lu Xiuyuan pointed to a successful petri dish and explained: "See this yellow fungus? These are the bacteria cultivated in spoiled broth. People will get sick after eating spoiled broth. It's also made of this thing." of."

The other party nodded thoughtfully, and then pointed to the blank part in the center of the coccus.

"Then there is no growth here because of the penicillium you mentioned?"

"That's right, the penicillium we cultivated before can kill this Staphylococcus aureus..."

Hearing this, Shi Yunchen made some calculations, and hurriedly asked: "Then people with bad stomachs can use this treatment in the future?"

"It's more than that." Lu Xiuyuan smiled and explained to the other party: "It has many uses, such as wind and cold that can easily kill people's lives, infection caused by sword trauma... and so on, all of these can be cured with this."

These small injuries and colds in modern times can kill a person casually in ancient times.

The reason why ancient people seldom bathed was because they were prone to colds and caused fever and cough. Pneumonia caused by pneumococcus is very sensitive to penicillin, including infections caused by traumatic Staphylococcus aureus. There are countless diseases that can be treated.

But remember to control the dosage, don’t just solve everything with penicillin, otherwise the loss outweighs the gain when drug resistance develops in the future.

After hearing his explanation, the young master's eyes became brighter and brighter.

"Erlang! How could there be such a powerful magic medicine! Then when this medicine is produced, wouldn't the wounded soldiers on the border be saved!"

Lu Xiuyuan didn't have the nerve to attack the other party, as this kind cannot be mass-produced, it must be extremely scarce after research, not to mention that penicillin can also treat certain venereal diseases, and those nobles with chaotic private lives will definitely break their heads.

Shi Yunchen blinked, and then asked a question: "But since it was taken out from the melon, can the soldiers be treated directly with this penicillium if they are injured?"

"Naturally not. There are various types of blue mold, not necessarily the one that is harmless to the human body. If it is used directly, it is indeed a gambling element."

Lu Xiuyuan thought of an analysis report he had read before. Regarding the isolation and identification of pathogenic bacteria from melon rot tissue, a research institute isolated 22 strains of the fungus, of which only two strains were Penicillium.

The fungus they took directly on it now may be more likely to be Penicillium, but other harmful strains cannot be ruled out.

For example, patulin, which also grows on fruits, is easily soluble in water, has similar properties to penicillin, and has a broad-spectrum antibacterial effect, but it also has a characteristic that penicillin does not have, that is, it is harmful to the human body and can cause gastrointestinal function. Disorders and edema-bleeding of various organs.

"Oh, alright." The young master's eyes dimmed again: "Then can the things in front of you be used directly by others?"

"I don't know, that's why I prepared this." He picked up the cage next to the mouse.

Whether it is penicillin, which is harmless to the human body or other toxins, can be tested with mice, and the results can be known at a glance.

The other party was obviously surprised when he saw the mouse: "So you let people catch mice for this purpose?!"

At first, Yun Chen didn't understand why he caught mice. That thing was dirty and smelly. If one was lost, the yard would not be peaceful. He hated it, so he only prepared thirty...

Looking at the densely packed petri dishes in front of me, it is obvious that thirty are not enough at all...

The other party glanced at Lu Xiuyuan with a guilty conscience.

Seeing this, he began to sell miserably: "That's right, that's why I said fifty may not be enough..."

Shi Yunchen felt even more guilty: "Erlang is my fault this time, you wait, I'll let Nan Xing go to the market to spend money to buy, let alone fifty, I'll give you a hundred or two hundred Get it!"

Seeing that the other party really wanted to get up and leave, Lu Xiuyuan quickly stopped him.

"Wait, let's finish trying these thirty."

Shi Yunchen was dragged back to his original seat again.

"Achen, when I give it an injection later, you tie the rope with the label corresponding to the liquid to its hind legs, and remember to wear gloves."

Rats like this are wild and dirty, and if their fingers are bitten, there is no vaccine to prevent them.

After finishing speaking, Lu Xiuyuan selected a fungus that seemed to be the most lethal among the petri dishes, took out an appropriate amount of liquid with a needle, then put on thick gloves, and began to reach into the cage to randomly grab a lucky mouse for experimentation.

Stretching his big hand in, the rats in the cage were not afraid of people. He grabbed one without a hitch, and then cooperated with his left and right hands to successfully make the rat put his belly up.

There is no povidone iodine here, anyway, it is a one-shot deal, so there is no need to consider disinfecting the injection site of the mouse, so Lu Xiuyuan directly poked it in with a needle.

The mouse began to struggle desperately under the pain, but it was futile in the end because it was fixed firmly.

After Shi Yunchen tied the numbered rope, he put the mice individually into another large cage so that he could observe the condition of each mouse.

Lu Xiuyuan also heaved a sigh of relief after injecting all thirty mice continuously.

"Let's go take a shower first, this mouse is really dirty."

A little bit of resistance, both physically and psychologically.

Shi Yunchen nodded, and then said: "Then why don't you let Nan Xing go to the homes of ordinary people on the street to talk about buying mice?"

Lu Xiuyuan thought for a while, the possibility of success in one attempt is not very high, it is better to charge more for experimentation.

"Then let Nan Xing take a little of it from the hands of the common people first."

He put the previously used needles in a separate pile, and after a while he asked someone to boil them in boiling water for disinfection, including the gloves used just now.

The two washed their hands carefully together, and then went to take a brief shower.

After coming out, Lu Xiuyuan went to inspect the condition of the thirty mice without eating.

The liquid he injected before had the strongest antibacterial effect. If the mouse died, it meant that it was not penicillin but patulin or other antibiotics.

The two came to the place where the experiment was done just now. The scene in the cage made Lu Xiuyuan's heart sink.

He thought that the possibility was not high, and he might not be able to succeed in one attempt, but when the failure was really in front of him, he couldn't help but feel a little disappointed.

Shi Yunchen glanced at the dead mice in the cage, then at Lu Xiuyuan, and couldn't help but reached out and gently pulled off his cuff.

"Erlang, I have asked Nan Xing to find mice, and I can continue the experiment later."

Lu Xiuyuan wrapped his hand around the opponent's palm and shook it lightly: "Achen, I'm fine. It's normal for the experiment to fail. I've been mentally prepared for it."

This is only [-] copies of the mold of a melon, and he is ready to continue with the mold of steamed buns after all failures, so naturally he will not be hit by this result.

After cleaning up the scene, they went to take a shower before eating

In the afternoon, when Nan Xing and the guards entered the backyard carrying more than 100 mice, Lu Xiuyuan was stunned.

"Why so many?!"

He quickly looked at Shi Yunchen next to him: "Didn't you say that fifty would be enough?"

"Don't look at me, I don't know." The other party quickly brushed it off.

In the end, it was Nan Xing who put down the mouse and came over to explain: "Grandpa, the guard and I went to buy it from broken houses and houses according to what the young master said. Those people didn't believe it at first, but after seeing that we really gave money, we went directly to the Seventh University." Auntie and Auntie are all mobilizing to catch mice!"

Nan Xing was on the verge of tears while talking: "I didn't expect there are so many rats in the capital! When we went there again in the afternoon, those people had already caught so many rats!"

In this case, it is not easy to refuse. What if no one will be arrested next time if you refuse this time?Nan Xing could only cry and wanted everything.

"That's all, I bought it when I bought it, and I will use it again in two days."

It’s okay if you can’t use it up this time, and these mice can still be used after the wave of culture fluid from Mantou comes out seven days later.

Lu Xiuyuan comforted Nan Xing casually, and let them retreat first, while he put on gloves with Shi Yunchen and continued the morning action.

Carefully opened the mouth of the cage, touched a mouse out from inside, fixed it according to the standard action, and began to inject the drug liquid.

After finishing, the young master tied the rope, and then threw it into the big observation cage.

This time, because there were more specimens left, they waited until the next injection, and the mice that had been injected before had already started to respond.

Hearing the miserable screams of the mice one after another, Lu Xiuyuan continued to randomly select lucky mice in the cage without changing his expression.

It's just that the mouse caught in his hand was different from other mice, and the other mouse actually bit him when he reached out his hand.

Wearing thick gloves on his hands, he felt nothing in his fingers. He continued to skillfully turn the mouse over to inject the liquid, and then threw it into the observation cage full of miserable screams.

The two rats that screamed the worst in the cage just now started to foam at the mouth. Lu Xiuyuan looked at the remaining specimens, and there were only twenty more.

When he injected all the specimens in one breath, it was only a stick of incense time.

The two washed their hands together, and then took advantage of the observation period to separate and dispose of all the fungus in the steamed buns.

When Mantou's work was over, the mice in the observation cage here also came out.

Looking at a large number of mice that had died again, Lu Xiuyuan's face was calm, and he could not see any emotional changes.

When standing next to him, Yun Chen sneaked a look at him, a little worried about his state.

"Erlang, the penicillium on the steamed bun will produce results after seven days. Let's try again then."

Glancing at Shi Yunchen, he saw that the other person's eyes were full of worry.

Probably because he was afraid that he would feel bad, he curled his lips and smiled.

"I'm fine, at worst, try again in seven days."

Penicillin is not something unknown, it actually exists in life, as long as he tries more, he will succeed sooner or later!

He was just regretting that he didn't cultivate it on Melon for the first time.

Sighing inwardly, Lu Xiuyuan was planning to clean up the mess with the other party, when he turned his head, he caught a glimpse of something moving in the pile of corpses out of the corner of his eye.

"Shh, wait a minute." He reached out his hand to stop Shi Yunchen from opening the observation cage.

"I just thought I saw a mouse move."

As soon as these words came out, the other party's eyes lit up instantly.

Wouldn't it be a success if the mouse survived? !

Lu Xiuyuan held his breath and went closer to the observation cage to observe carefully. The rats inside died in the same way, and many of them were foaming at the mouth or collapsing on the ground with dark liquid.

So when he glanced over, the dead mouse with its four claws facing the sky immediately came into view.

This action seemed to be pretending to be dead, and Lu Xiuyuan's heart gradually began to pick up. Whether today's experiment can be successful depends entirely on this mouse.

He reached out and found a small wooden stick from the side, and poked it lightly through the gap.

The opponent's body swayed from side to side with the push of the wooden stick, as if he was really dead.

But he knew that the mouse was actually very cunning and good at disguising, so he didn't necessarily die if it was real.

After waiting for about 2 minutes, the mouse still had no response. Lu Xiuyuan outside the cage couldn't wait any longer. Instead of making the mouse feel safe before returning to normal, he would add fuel to the fire.

Putting on the gloves again, he reached into the cage and pulled the mouse up by its hind legs. Seeing that the mouse was still motionless, he touched the needle tube beside him and poked it twice with the sharp needle.

Feeling the familiar pain, the upside-down mouse instantly opened its eyes and screamed.

Seeing the healthy and lively appearance of the mouse, Lu Xiuyuan finally breathed a sigh of relief, and then shook the mouse's hind legs.

"Little guy, you're pretty good at pretending? I was almost tricked by you today!"

The author has something to say: Crying and crying, I often walk by the river without getting my shoes wet, and I was finally caught on the 22nd day of adopting a kitten. I would like to provide a rabies vaccine package.

It took half a day to go to the hospital for an injection during the day, how about adding it to tomorrow? qaq
