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

There were no patients in the outpatient room for the time being, and Li Ping'an did not stay any longer. He washed his lunch box at the canteen sink and left.

After returning home, Qin Huairu followed him to his room and said, "Brother Li, can you find me a book that explains how to handle medicinal materials? Aunt Mei asked you to teach me some methods of preparing medicinal materials. I will learn it later." When you help at the pharmacy, you won’t be in a hurry!”

Li Pingan nodded.

He took out a book explaining Chinese medicine from the cabinet under the bed and gave it to Qin Huairu. He sat next to her and explained to her the preparation methods of Chinese medicine, the uses of related medicinal materials and the involved prescriptions.

Qin Huairu silently remembered what Li Pingan said.

Three or four hours later, she suddenly said: "Oops, I almost forgot. I washed your clothes in the morning and they should be dried. I have to go get them back!"

Li Pingan nodded and stopped explaining.

Xu went to collect clothes with her.

As soon as they arrived at the middle courtyard, they found Jia and Zhang's mother and son back in embarrassment.

Jia Dongxu had not touched a bicycle for several years, and his skills were not good. In addition, he felt uncomfortable when his marriage proposal was rejected. When he came back, he did not have a good grasp of the direction and plunged into the cornfield on the roadside.

What a coincidence.

At this time, the corn is about to mature. After the last irrigation, the ground is full of water.

The mother and son got stuck in the cornfield as soon as they entered it, and it was with great difficulty that they pulled the bicycle out of the mud.

There was little tidying up on the road, and both mother and son were covered in mud.

Especially Jia Zhang. When she fell off the bicycle, she was chewed by a dog. She was covered in mud and saw that she could no longer wear the clothes she had just washed.

Xu and Qin Huairu looked at each other and thought to themselves: "Fortunately, they didn't lend their bicycles to the Jia family. He would be heartbroken if his new bicycle was treated so badly!"

The two collected their clothes and returned to the backyard.

Qin Huairu helped Xu make dinner.

As soon as dinner was cooked, Li Lin came back from get off work.

After dinner, when Li Pingan sent Qin Huairu back to the hospital dormitory, he found three members of the Jia family cleaning bicycles next to the sink.

Lao Jia was still mumbling: "Dongxu, why aren't you more careful? You were walking well on the road, but why did you end up in someone else's cornfield? I paid someone to borrow one." Bicycles, if people knew that you made the bicycles like this, they wouldn’t have to ask for more money from our family!”

After leaving the courtyard, Qin Huairu chuckled and said, "Jia Zhang's son rode his bicycle into the cornfield. When my mother and I went to the courtyard to collect clothes, they had just come back and were in a panic. !”

"Fortunately we didn't lend them our bicycles!" Li Ping'an said with a sneer: "Otherwise, if the bicycles belonged to our family, based on Jia Zhang's character, she might not have cleaned them for us at all!"

He heard his mother Xu say it.

Mrs. Jia Zhang does not regard herself as an outsider at all, and is not polite at all when she borrows things from her neighbors.

Qin Huairu brought a book from home to the dormitory to read, and said to Xiao Lu on the upper bunk: "I am learning how to prepare medicinal materials now, Xiao Lu, if there is something I don't understand, can you teach me?"

"This!" Xiao Lu sat up and shook her head and said, "I know only a little bit about Chinese medicine. If you ask me what to do, if you have any questions, go to Dr. Li. The first to get closer to the water, the better to the better, he will definitely give you careful advice. !”

Qin Huairu nodded, but was thinking in her heart: "Aren't I afraid of delaying his work?"

In the laboratory.

The bacterial fermentation is completed.

Li Pingan took Qin Huairu into the laboratory.

He took out more than a dozen control groups from the biological test chamber and conducted microscopic examinations one by one.

Li Pingan sterilized the biological experiment box before placing the culture medium.

but.

After ten days of fermentation, miscellaneous bacteria still appeared on the culture medium.

After comparison.

Li Ping'an selected the group of culture media with the best growth of chrysanthemum-producing bacteria and the least miscellaneous bacteria.

He checked the material composition data of this set of culture media.

Let Qin Huairu grind the corn flour.

According to the results of the last experiment, refer to the various components of the selected group of culture media.

It was also adjusted according to the suitable living conditions of chrysanthemum-producing bacteria.

A dozen white corn steeple media were recreated with slightly different compositions.

The culture medium was re-inoculated with yellow penicillin, and the treated culture medium was still put into the biological experiment box.

Next comes another long fermentation period.

later generations.

During the fermentation of chrysanthemum-producing bacteria, phenylacetic acid or phenylacetamide is added as a precursor, which can control the direction of antibiotic synthesis and increase production.

but.

Li Ping'an couldn't find these two substances at all. He could only use the pH, temperature and other conditions of the culture medium to screen for chrysanthemum-producing bacteria. This required a large number of experiments and repeated adjustments to the proportion of culture medium ingredients.

The task was completed within two hours of working in the laboratory.

When Qin Huairu came out of it, she smiled and whispered: "Brother Li, this job is too easy!"

"Yeah!" Li Ping'an nodded and said nothing more.

If he had not had the experience of later generations, even if he had been given hundreds or thousands of people, it would not have been possible to find a rough preparation method for white corn culture medium in such a short period of time.

The progress of the experiment is absolutely impossible to be so fast.

It was still early before getting off work, and there was no scheduled surgery. Li Pingan asked Qin Huairu to continue helping in the pharmacy, while he went to the outpatient clinic to receive treatment with his father.

A woman in her thirties brought Lou Xiaoyong over for a follow-up consultation, and Lou Xiao'e followed behind.

Time will not defeat the beauty, and time will live up to the passing years.

The woman was wearing a cheongsam, and she exuded a graceful temperament. She said to Li Lin: "Doctor Li, I brought Yong'er for a follow-up consultation. Please help see if he is completely healed!"

The woman is Tan, Lou Zhenhua's wife and Lou Xiao'e's mother.

Li Lin was very popular, and people living near the courtyard would come to him for treatment when they were sick.

The Lou family has two children, and Lou Zhenhua and his wife often interact with him.

After two or three days of immobilization, Lou Xiaoyong's temporomandibular joint has fully recovered.

"It's healed!" Li Lin said with a smile: "Ping An, please take off the four-band belt on the child's head!"

Li Ping'an carefully took off the four-band strap and threw it into the trash can at the door.

Mrs. Tan breathed a sigh of relief, looked at Lou Xiaoyong with a smile and said, "Yong'er, how do you feel?"

Lou Xiaoyong opened his mouth, feeling more confident. He did not answer Tan's question, but said to Lou Xiao'e fiercely: "Lou Xiao'e, if you dare to harm me, just wait. I will take over the Lou family's family when I grow up." Everything, see if I don’t kill you, I want you mother and daughter to look good, I will drive you out of the Lou family!”

Lou Xiao'e was scared.

She had never seen her brother look so ferocious before. She ran behind her mother and cried and said: "I didn't harm my brother. He put chili noodles in my bowl. I was so spicy when I ate. Brother Your jaw dropped when you smiled, you can’t blame me!”
