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

With the certification letter in hand, Li Ping'an and Qin Huairu first went to the hospital to go through the procedures for her, established a personnel file, and then went to the police station to transfer her household registration.

Complete all formalities.

Qin Huairu has truly taken root in the city.

Li Ping'an couldn't wait to enter the laboratory and prepare to start experiments.

White corn is rich in starch and protein, and also contains a variety of minerals. If white corn is used to make the culture medium, lactose, peptone, potassium hydrogen phosphate and other substances can be omitted. Just add some yeast extract and salt.

The first thing to do is grind the white corn.

There was no grinding equipment in the laboratory, so Li Pingan asked Qin Huairu to borrow a medicine from the pharmacy and grind it.

Unfortunately.

When Qin Huairu arrived at the pharmacy, the supervisor, Aunt Mei, was preparing Chinese medicine and didn't want to talk to Qin Huairu at all.

Aunt Mei is an old man in the hospital. Li Ping'an heard from his father that she entered Daoji Hospital earlier than Li Lin. When the Americans took control of the hospital, she was the pharmacy administrator. She was already very good at grabbing medicines and preparing medicinal materials.

He is older, has senior qualifications, and has good skills. He is somewhat arrogant about his talent. Even when he meets ordinary doctors, he always seems to be indifferent, let alone Qin Huairu?

Qin Huairu was not upset and kept helping Aunt Mei. After more than two hours, Aunt Mei stopped what she was doing before crushing the medicine to her.

He took the medicine and ran back to the laboratory.

Qin Huairu started grinding the white corn, and Li Ping'an didn't stop until she felt that the white corn flour in the medicine grinder was almost the same thickness as the corn flour used in later laboratories.

Li Pingan then used a centrifuge to prepare yeast extract and added salt.

The required materials are almost ready.

The next step is to calculate the mixing ratio of various substances.

If this matter were very simple in future generations, various nutrients could be quickly detected and configured according to the growth needs of chrysanthemum-producing plants.

But it's different now.

His eyes darkened.

Lack of various data support.

Li Ping'an could only roughly guess the nutritional content of white corn based on his impression of later experimental data.

He made more than a dozen control groups, and after the experiment, which medium was more suitable for the growth of chrysanthemum-producing bacteria was used.

It took a whole day of work to prepare the culture medium control group and put it into the biological experiment box.

"Huairu, you have dinner in the hospital cafeteria, don't go home!" Li Ping'an said to Qin Huairu when he got off work: "Also, I have to go to Beijing Medical University tomorrow to collect the strains, and I may have to come to work a little later. Just wait for me in the dormitory first, you don’t have to come to the lab!”

Qin Huairu nodded in agreement.

After Li Ping'an returned home, she went to the cafeteria to have dinner and then returned to the dormitory.

When she arrived at the dormitory, she found that Xiaolu was not there, so she asked Feng Wenwen about Xiaolu's whereabouts.

"Xiaolu asked the head nurse for leave yesterday, saying she was not feeling well. She took leave for two days. She just left this morning and she probably won't be here tomorrow!" Feng Wenwen explained.

Qin Huairu was a little worried.

Wang Chunyan pursed her lips and smiled and said: "Don't worry, she doesn't have any serious illness, it's just her first menstrual period and she was scared. She will be back to work after two days of rest!"

"So that's it!" Qin Huairu whispered with a blushing face.

She remembered the first time she had her period. Although she was anxious, it was nothing serious.

the next day.

Li Pingan went to Beijing Medical University early in the morning.

Union Medical College and Union Medical College were temporarily closed during the war, and the medical school did not resume enrollment until the eighth year after the founding of the People's Republic of China.

at this time.

Beijing Medical University is the best medical university in Beijing and even in the country, and they take the lead in the research on penicillin preparation here in Beijing.

All units participating in scientific research must go to the Medical University to receive bacterial strains and inoculation tools.

When we arrived at the collection location, there were already more than a dozen people queuing up in front. They were mainly staff from the First Hospital, the Second Hospital, and Union Hospital, which also have medical laboratory units.

Finally it was Li Ping'an's turn.

A staff member in a white coat carefully inquired about Li Ping'an's unit, laboratory conditions, and researchers.

When I learned that Li Ping'an was from Daoji Hospital and that there was only him, a person who had attended medical school for two years, and Qin Huairu as an assistant in the laboratory, I was a little dissatisfied and didn't want to give him bacterial strains.

then.

Because culture media cannot be produced domestically, most bacterial strains are imported from the Soviet Union.

expensive.

You can't just give it to Li Ping'an casually.

If Li Ping'an makes no achievements in experiments and cannot develop a new suitable culture medium, it will be useless even if he brings the bacteria back. It won't take long for the culture medium to be invaded by other bacteria, and the yellow penicillin-producing bacteria will also be invaded. Disappears quickly.

Even in the early days of the founding of the People's Republic of China.

There are also many medical talents in Beijing.

Take the Union Medical College Hospital as an example. They have several medical students who graduated from Suzhou, and they even have two talents who graduated from the First Medical University of Moskva.

MoSike First Medical University is the most famous medical university in Suzhou and is world-famous.

Naturally, the bacterial strains must be supplied to them first, and even a little bit does not want to be wasted on "miscellaneous fish" like Li Ping'an.

"Comrade, our Daoji Hospital has a good laboratory. All the equipment in it is produced in the United States!" Li Ping'an hurriedly explained: "I, when I was in school, I simulated a penicillin preparation experiment with my teacher!"

Worried about being questioned, Li Pingan did not dare to say that he had done experiments on penicillin preparation, and it was quite successful.

The staff remained unmoved, and it seemed that they did not intend to give Li Ping'an the bacteria.

At this moment.

A young girl of sixteen or seventeen years old, wearing a nurse's uniform, walked up to the staff member and whispered something to him.

Li Ping'an had a very good ear, and he understood the general meaning of the girl. It seemed that Professor Chu had told the staff to give him the bacteria.

The girl turned and left, ignoring Li Ping'an.

The staff looked at Li Ping'an in surprise and gave him the strains and inoculation tools.

Li Ping'an and Monk Zhang Er were also confused. He didn't know what was going on and who helped him.

Without thinking much, he took the bacteria and left.

Xiao Lu walked out from the corner, looked at Li Ping'an's retreating back, and said to the girl who greeted the staff before: "Sister Zhou, thank you very much this time!"

Returning to the laboratory of Daoji Hospital, Li Ping'an used an inoculation loop to inoculate the penicillin-producing bacteria onto the culture medium, locked the door and left the laboratory.

The next step is to ferment for seven to ten days without having to worry about the lab.

Li Ping'an went to the door of the nurse's dormitory and asked the administrator's aunt to call Qin Huairu out and told her that the laboratory would be fine for the next week and there was no need to go there.

"This, this is my job!" Qin Huairu frowned and asked, "How can you ignore it?"

"It's not just you, I won't go to the laboratory in the next time!" Li Ping'an said: "If you can't wait for Xiaolu to come back, follow her and ask her to help you find some jobs within her ability!"

The head nurse had already informed him about Xiaolu's request for leave.

Li Ping'an knew it.

"I know!" Qin Huairu agreed obediently.
