Siheyuan: Rebirth in a prosperous era, great doctors are sincere

Wang Chunyan did not participate in the operation this afternoon.

but.

Qin Huairu was not asleep when the three of them returned to the dormitory.

Lying on the upper bunk, she could clearly see the behavior of her three roommates.

Eat the braised pork.

Feng Wenwen was lying on her bed and asked Qin Huairu: "Sister Qin, are you married to Dr. Li? Why haven't you ever mentioned anything between you to us?"

Feng Wenwen was a little curious.

She had been in the dormitory for so many days and had no idea about the relationship between Qin Huairu and Li Ping'an. If she had known about it in advance, she would have been more polite to Qin Huairu.

"No, they just got engaged!" Xiao Lu said: "Dr. Li only told me about the relationship between the two and asked me to take care of Sister Qin!"

Xiaolu was quite proud.

She was the youngest among the roommates, but Dr. Li chose to ask her for help.

visible.

Li Ping'an quite recognized her ability.

"It's a pity that the braised pork is still a little short. I'm not full. The braised pork made by my aunt is so delicious. Sister Qin, if my aunt makes braised pork next time, please save some for me!" Xiao Lu Then he said: "What if my mother also makes delicious food for me and I bring you some?"

Qin Huairu nodded in agreement.

Feng Wenwen also said: "My mother also has a few specialties. If I have a chance, I will bring you some to try!"

Wang Chunyan remained silent.

She felt that she and Zhou Ling were both blind because they didn't realize that Qin Huairu was Li Ping'an's fiancée.

If they had known about this situation, would they have targeted Qin Huairu everywhere?

If Zhou Ling was a little nicer to Qin Huairu and had Dr. Li help her, would she still have to marry Yang Wenying against her will?

Fortunately, the vice-president's niece-in-law became a widow within a few days.

An unjust death.

Wang Chunyan secretly rejoiced in her heart. Fortunately, she didn't help Zhou Ling when she made things difficult for Qin Huairu. Otherwise, she would regret it to death now!

"Xiaolu!" Wang Chunyan said, "I haven't finished the steamed buns I bought for dinner, and there's only half of it left. Why don't you eat it?"

Wang Chunyan was somewhat flattering.

She figured it out.

Xiaolu has a good relationship with Li Pingan and Qin Huairu.

later.

If she wants to live a better life in the surgery team, she must have a good relationship with Xiaolu and Qin Huairu.

"No need!" Xiao Lu said, "I'm going to bed. I'll bear it and eat tomorrow. My mouth is full of the smell of braised pork and I can't eat the steamed buns anymore!"

Wang Chunyan was a little disappointed.

Feng Wenwen turned off the light.

The dormitory was dark.

Soon.

They all fell asleep.

The news that Qin Huairu was Li Ping'an's fiancee spread quickly in the hospital as if it had wings.

The older nurses were disappointed.

Li Ping'an was good at both surgery and Chinese medicine. He was a hot commodity. Many nurses wanted to date him. They didn't expect him to get engaged so quickly.

Li Ping'an was called over by the director as soon as he arrived at the hospital for work.

The dean smiled and asked: "Dr. Li, you are studying Western medicine, have you ever been in contact with a laboratory?"

laboratory?

Li Ping'an was stunned.

Very distant memories are reawakened.

When he was studying in later generations, his chemistry scores were very good.

inorganic chemistry.

Organic Chemistry.

Analytical chemistry and biochemistry are among the best in the class.

When doing experiments, many school girls are willing to work with him. It is very worry-free. You don't have to do anything, just wait for the final copy of the experiment report.

Li Ping'an's expression made the dean misunderstand. He thought Li Ping'an remembered the experiments he did when he was in school.

The dean smiled and said: "It seems that you know how to do experiments. Just so I have a very difficult task for you!"

The task assigned to Li Ping'an by the dean was to study how to prepare penicillin.

After the founding of the People's Republic of China, superiors have always attached great importance to the research and development of penicillin.

Demon City is at the forefront in this regard.

Under the care of Mayor Chen, a research institute was established, and many specialized talents are studying the mass production method of penicillin.

Daoji Hospital also has a complete laboratory, which is very advanced. Many experimental equipment are made in the United States.

The dean wanted to respond to the call from his superiors to utilize the laboratory and conduct some basic experiments on the development of penicillin. After thinking about it, only a young man named Li Ping'an could take on the important task.

How to mass-produce penicillin with the help of laboratory research?

Li Pingan was very interested.

In later generations, he saw the development history of penicillin.

After the founding of the People's Republic of China, superiors began to make great efforts to develop penicillin.

It didn't take long for someone to bring the Penicillium chrysogenum strain used in the production of penicillin and the method of making penicillin to the country, and the preparation of penicillin in the laboratory was successfully completed.

just.

A problem arose when trying to mass-produce it.

There is no domestically produced medium for cultivating chrysanthemum-producing bacteria.

At that time, corn steep liquor culture medium was used to cultivate chrysanthemum-producing culture, and lactose was also used.

There are several chemicals in the corn steep liquor culture medium that cannot be produced domestically, and the same goes for lactose.

In the fifth year after the founding of the People's Republic of China, the Magic City developed a culture medium using cottonseed instead of corn steep liquor. However, due to the lack of lactose, penicillin could not be mass-produced.

It was not until the eighth year after the founding of the People's Republic of China that the white corn culture medium was developed, which eliminated the expensive lactose and solved a global problem. Since then, penicillin has been produced in large quantities in China, and the price of penicillin has completely dropped.

Li Ping'an has an advantage in studying penicillin mass production methods.

The biggest advantage is that he knows that using white corn to make culture media can solve the problem of unavailability of corn steep liquor culture media and lactose, and he can prepare penicillin completely relying on domestic raw materials.

and.

He knew too much about the technology of making penicillin.

The temperature and pH required for cultivating bacterial strains cannot be known enough.

If the problem of the culture medium is solved, mass production of penicillin can basically be achieved.

It is now the fourth year after the founding of the People's Republic of China.

If Li Ping'an could solve various problems faced by the mass production of penicillin, it would be equivalent to saving four years of time.

even.

If Li Pingan publishes the various conditions required in the production process of penicillin, and uses his method to cultivate Penicillium chrysogenum, there will be fewer miscellaneous bacteria, and the purity of the produced penicillin will be greatly improved, which may not be better than that of the United States and the United States. Su Guo's difference can be regarded as overtaking in a corner.

"Dean, don't worry, I will do my best to make good use of our laboratory, cooperate with my superiors to complete various experimental tasks as soon as possible, and do my part in the research and development of mass production of penicillin!" Li Pingan said thoughtfully: " I promise you that it will not affect my job. I will definitely do a good job in the surgeries that need to be performed. Until there are no results in the laboratory, I will definitely focus on my job!"

The dean nodded and said: "This is the best, we will leave the laboratory of our hospital to you!"

Li Pingan was overjoyed.

Qin Huairu returned to the dormitory after working at Li's house all day.

She met Zhou Ling when she went to the sink in the yard to get water for washing her feet.

Qin Huairu was stunned for a moment and deliberately avoided her.

How to know.

Zhou Ling quickly blocked her way and said in a cold tone: "Qin Huairu, I didn't expect that you are actually Li Ping'an's fiancée. You are really good. You have been hiding this matter from me. Why, you guys look down on me. , didn’t you take me seriously?”

"No!" Qin Huairu shook her head and said, "You are all nurses in Brother Li's surgery team. I'm afraid that telling you will cause a psychological burden on you. It's better to hide it. Brother Li and I have discussed it and wait until we get married. I’ll call you all over when the time comes.”

Zhou Ling became angry when Qin Huairu mentioned the matter of getting married.

Qin Huairu had a happy marriage, but she ended up miserable. She was extremely jealous. She said in a cold tone: "Qin Huairu, you are not a worker in our hospital. Why are you living in the dormitory of our hospital? Move out quickly if you know how to do it." Get out, and don’t let me report you to the deputy dean and say bad things about you!”
