doctor knife in hand

In the Duke's Mansion, the old butler with his injured leg directed the servant girl to count the broken utensils, arrange and seal up the surviving porcelain ornaments, and sweep the house by the way.

Song Heng often lived in the palace when he was a child, and joined the army to fight when he was older. He didn't live in the mansion for many days, and he didn't pay attention to luxury, so almost all the decorations in the Duke's mansion were made when Mrs. Qiao was there.After Lu Jin moved in, she didn't care about these things, and never changed them.

The things of some years may not look new, but they are all good things and look good. However, when the earth dragon turned over, some bottles and jars fell to the ground, and most of them fell. The old housekeeper felt very distressed, and they were broken The tiles were reluctant to be thrown away, and the servants carefully put away the intact ones, and waited for the aftershocks of the trembling on the ground to completely pass before taking them out.

The old butler was instructing his servants to put a pair of surviving double-eared floor-to-ceiling painted bottles into the warehouse. It was getting dark, and the rest would be sorted out tomorrow, but suddenly he heard a report from outside, saying that Lu Jin had returned .

When the catastrophe came, Lu Jin was afraid that he was very busy, and he came back so late, so it was obvious that he had something important to do, so the old housekeeper limped out, and happened to meet Lu Jin who was in a hurry. In the dark, his Although he couldn't see clearly, he could still feel the urgency.

As soon as Lu Jin saw him, he hurriedly asked, "Uncle Fu, where are the things in that laboratory?"

The laboratory pointed to the penicillin-making room. Seeing that Lu Jin was sweating in a hurry, the old housekeeper immediately comforted him: "The room is not strong. I was afraid that it would fall down and damage things, so I sent someone to put it away." ... Ah Xiang, Ah Xiang!"

The old housekeeper yelled loudly, and a servant hurried over, "Father, call me."

"It turns out that in the west room, Mr. Lu took the two young masters to make medicine. The things in it have been sent to the small warehouse. You should take the young master to look at it quickly. Bring more people, light the torches, and light it up. It's broken."

"Hey, Mr. Lu and the little one are here."

The small warehouse has been strengthened a lot. Look at the tight appearance, even if the earthquake is stronger this time, it will not collapse.

Inside are fragile things such as porcelain, which are carefully supported by strong wooden frames, so that they are not afraid of being shaken and smashed.

Lu Jin's experimental equipment was placed at the entrance.

Ah Xiang led someone to take it out carefully, and said: "Father said that these bottles and cans are very important to you, Mr. Lu. I'm afraid they will be used later, so let them be placed outside. Sure enough, you can find them." coming."

There is no need to look at other things to see whether a family has a strong foundation, but to look at the behavior of the housekeeper in the house. If it is thorough and meticulous, it must be not an ordinary family.

Lu Jin wandered around in the small warehouse, looking at the petri dishes, the ceramic tubes were taken out one by one, and placed on the flat ground outside, with a thick blanket on the ground as a cushion, a servant stood watching, afraid of being knocked Touched, my heart is very emotional.

After the earthquake, He Lan went to see the laboratory regardless of the danger. Most of the things were not damaged. At that time, he was in a hurry to go to the north and west of the city, so he didn't care.

He knew that penicillin would not be developed anytime soon, and saving lives was more important, but unexpectedly, he still couldn't get around it after going around.

There was a lid on a porcelain jar, and the look of the servant carrying it out was still heavy. He squatted down, opened it, and found that there was still half a jar of solution inside.

He thought for a while, and remembered that it was the penicillin solution that was extracted for the last time three days ago. He Lan asked him what to do with the extra penicillin solution after the experiment, so he asked him to put it away.

The bottom of the tank is white, and it can be seen that the solution has become turbid and slightly yellowed. I don't know whether it is the yellowing under the firelight or itself.

Lu Jin has been thinking about why he failed all this time. Did he propose penicillin solution?

Seeing the yellowing solution, he suddenly stood up, looked in the warehouse, and saw that there was still a blue and white porcelain bowl inside, so he asked Ah Xiang to take it out as well.

He poured some of the penicillin solution into the bowl, moved the torch a little farther away, and observed it carefully. He always felt that the liquid was still yellow.

"Master Lu, where are you going to send these things?"

Ah Xiang took out all the utensils and asked Lu Jin who was squatting on the ground.

Lu Jin was frowning and thinking about the liquid in the white porcelain bowl, Ah Xiang scratched his scalp and wondered if he should remind him again.

"That's right..." Suddenly Lu Jin uttered a voice, Ah Xiang looked over with a dazed expression, "Master Lu?"

Lu Jin got up slowly, came back to his senses, looked at A Xiang and said, "Sterile, sterile, I've been talking about it for so long, but I forgot such an important step when I was doing the experiment! It’s useless work, the instruments and equipment are not sterilized, even if the proposed penicillin has medicinal properties, it would have been neutralized long ago, not to mention that the concentration itself is not high.”

Ah Xiang's dazedness turned into stupidity in an instant, he couldn't understand what Lu Jin was saying at all.

The penicillin solution is colorless, but now it has become turbid, and has been mixed with various bacteria, whether it entered later or was in the production process, in short, Lu Jin got an idea.

Lu Jin ignored him. He felt that it was time to think carefully about how to solve this seemingly easy but actually difficult entire aseptic process.

"Ask if all the manuscripts in Ling Xuan's study are there?" He suddenly asked Ah Xiang.

Ah Xiang was stunned for a moment, and then replied: "Yes, yes, Dad put away all the fragile and valuable things, and he didn't dare to touch your manuscript."

Lu Jin nodded, and then said to him: "Sorry, these utensils are not used for the time being, please put them away for me, and I will send someone to pick them up in two days."

As he said that, he went to the study, and at the same time told the guards who followed him to go to the medical office to say that he would come back later tonight.

He sat in his study with a pen and paper in his hand, thinking hard.

In this era, there are no disinfectants, no sterilizers, and if you want to sterilize, only high temperature exposure is the most effective method. This is what he now wears when entering and leaving the operating room.

In the same way, it can also be used for the sterilization method of penicillin extraction.

It's just that the preparation and extraction is a long process, at least half a month, so just sanitizing the utensils is not thorough enough, it's better to do it for a long time.

If people want to work in a sterile environment, there is no doubt that the whole room should be sterilized.

Lu Jin drew a house, but after that, how to kill the virus at high temperature?

He subconsciously added two fires under the house... Well, it was a bit whimsical.

He rubbed his nose, and suddenly stopped rubbing.He thought of the kang head, using the heat generated by the firewood underneath to heat the room.

But another question arises again, to what degree can such a kang head heat the room, and can it reach the level of high temperature sterilization?If it is not achieved, it will become a breeding ground for other fungi to grow and reproduce?

Lu Jin felt a bit of a headache. Before the tiredness and powerlessness hit, he gave up this method and sat quietly for a while with his eyes closed.

There was a sound next to her ear, Lu Jin opened her eyes, and saw a maid from Song Heng's courtyard come in with a cup of tea, seeing him looking at her, she couldn't help being discouraged and said: "Fu Bo asked the servant to be more gentle, don't worry about it." If you disturb Mr. Lu, you will still be disturbed if you don't arrive first."

Lu Jin shook his head and signaled her to put it down, but when he saw the tea, he thought of the source of water, so he said, "You invite Uncle Fu, I have something important to tell him."

The servant girl owed her body and went immediately.

If a contagious disease breaks out, not only the people who have never met before will be affected, but also the people in the mansion, as well as the friends he made, their family members, and those who live in the capital, who can run away?

Although Lu Jin had a rough life and met many bad people, he also had many friends who were sincere and sincere. He really didn't want to see any of them with a sad face, or even never see them again.

He stared at the cup of tea and thought silently, the dense water vapor steamed up, and the fragrance of tea wafted out.

The refreshing tea fragrance relieved his exhaustion, and at the same time brought clarity to his chaotic thoughts, and then he stared at the tea in a daze.

In fact, there is another effective method for sterilization. Most of the fungi can be killed by using the high-temperature steam that evaporates for about an hour.

Thinking about it this way, it is only necessary to find a place that can continuously heat and evaporate water vapor.

Then this place...is there a hot spring in the capital?

After a while, the old housekeeper came.

He hurt his leg and walked slowly.

When Lu Jin saw him, he felt guilty, "I should have come to you by myself."

"You're busy, it's just a small injury, it doesn't matter."

Lu Jin stood up, moved him a chair, and told him to sit down. The old butler asked, "Your maid said you have something important to ask me, what do you want me to do?"

Lu Jin told him about the weather and speculation.

When the old housekeeper heard it, his face showed shock, and anyone who heard the word plague would change his face.

Lu Jin said solemnly: "It's fine if the rainstorm doesn't fall, but if it does come, Uncle Fu, you must remind everyone in the house that no matter where you get the water, you must boil it before eating and drinking. It's the same, but before eating, you should wash your hands with boiled water, and then treat the clothes you change in the same way. It would be better if there is sun exposure, try not to go out."

The old housekeeper nodded repeatedly, and recorded Lu Jin's words in his heart, "Don't worry, Mr. Lu, I will definitely do it."

Lu Jin said: "This method can only prevent, I hope nothing will happen, but if the disease is really found..." He paused, "Isolate him and let me know."

"Yes." Thinking of the horror of the plague, the old housekeeper couldn't help asking, "Then do you have a cure?"

It seemed that everyone would ask him that. Lu Jin picked up the cup of tea, looked at the faint steam and said, "That's another question, Uncle Fu, are there any hot springs in the capital?"

The old housekeeper didn't know what Lu Jin was asking about, but he still replied: "There are many hot spring pools in Tangshan in the suburbs, and almost all of them are owned by them. Our British government has two, one is near the top of the mountain, and the other is on the mountainside."

"Is it big?"

"The one on the top of the mountain is small enough for one person. The one on the mountainside is slightly larger. There are several small pools beside the big pool. The heat is just right, and it is the most comfortable to go in winter. It was just that last winter, when it was renovated, the adults didn't bring it with them. you go."

Lu Jin didn't want to go to the hot spring, and he didn't have such thoughts at this time. He just thought that the hot spring water has its own heat. Even if it can't achieve the purpose of sterilization, it will be much easier to heat on this basis. The continuous water vapor is enough Do an experiment.

Once penicillin is successfully extracted, the amount of use will increase greatly, but the amount extracted from wild fermented penicillin is very small. If you want to cure diseases and save lives, you may have to invest a lot of manpower in the production.

Lu Jin straightened her thoughts and was about to go to the medical office when she suddenly heard something coming from outside.

"It's raining!"

It's raining!Lu Jin rushed out of the study suddenly, and the big raindrops fell down, hitting his face with pain and pain.

The author has something to say: sterility is only one of the important factors in the extraction of penicillin, and there are other factors such as high-yield strains, temperature, humidity, PH value, fermentation, oxygen supply, etc., so penicillin could not be produced in ancient times.

As for why penicillin can kill bacteria, why should it be sterile, because most of the bacteria it kills, and many molds can be symbiotic.

All in all, it's good for everyone to watch it, and treat it as entertainment.

Mum, I love you guys!
