Ask Sword

".We are,"

Qiu Feng hesitated, then turned to Li Ang and said, "Successful?"

All the ceramic dishes in front of the two had their lids removed.

In each ceramic dish, there is a small round spot, which is particularly obvious in the yellow trace formed by the staphylococcus.

"Um."

Li Ang put down the ceramic cover, and nodded solemnly to Qiu Feng.

"Great!"

Qiu Feng cheered and hugged Li Ang warmly to celebrate this historic moment.

The two turned around in place several times before they realized that they were blushing and separated from each other.

"Cough cough."

Li Ang coughed to cover up his embarrassment, "These solutions already have medicinal effects, but they are still in a suspension state and can only be used externally.

Further filtration and crystallization are required.

How much spiritual power do you have? "

"It's fully recovered."

Qiu Feng brushed the hair beside his ears, lowered his head slightly, so that the reddish face on his face didn't look so obvious, "According to the previously established regulations?"

"Um."

Li Ang brought out a large bucket of solution from the refrigerator.

First add activated carbon, cooperate with talisman, freeze decolorization and dehydration,

filtered through sterile absorbent cotton,

Replenish water, heat with hot water jacket, add crystallization liquid potassium acetate,

(Potassium acetate is prepared by the acid-base neutralization reaction of potassium hydroxide and acetic acid)

(Heating calcium carbonate at high temperature produces calcium oxide, calcium oxide reacts with water to form calcium hydroxide, calcium hydroxide reacts with plant ash to form potassium hydroxide)

(Acetic acid is obtained by aerobic fermentation - a step similar to vinegar making. In order to speed up, Leon used a nineteenth-century German method, which is to fill a tower with wood chips, and drop alcohol-containing raw materials from the top of the tower. , inject air under the tower to force convection, so that Acetobacter bacteria can quickly produce acetic acid)

Mechanical stirring, azeotropic distillation for about one hour,

Filtration under vacuum pressure for 30 minutes,

Coarse crystals were obtained, which were washed with butanol to become wet crystals,

(Butanol is obtained by hydrolysis and fermentation of grain)

Pressed, sifted, dried, baked.

Fortunately, both Li Ang and Qiu Feng are monks, and they can use spiritual power to replace part of the mechanical operation.

When the salt-like crystals were brought out on a porcelain plate, the two subconsciously suppressed their breathing.

"This is"

"Medical penicillin."

Li Ang released his thoughts, causing the salt-like crystals to float up, pour them into a glass test tube, and cap the bottle.

Wrap it with several layers of cotton cloth and straw, and put it in the medicine box.

"Let's go."

He picked up the medicine box and smiled big at Qiu Feng, "Go save someone."

"Um."

Qiu Feng took a deep breath and stepped out of the greenhouse.

The Haotian bell rang, and the sky was just getting bright.

Chai Chai and Li Leling are still sleeping on the second floor - Li Leling's maids and guards are also in the laboratory building. Seeing Li Ang and Qiu Feng coming out, a female officer came forward to greet him, "Mr. Li Xiaolang is finished? Need me to wake you up?" Princess?"

"No, let her sleep."

Li Ang waved his hand, walked out of the back mountain, and took a carriage with Qiu Feng to Chang'an City.

Gululu——

The carriage wheels turn, the curtains are lifted by the morning wind,

The farmers who came to the city to sell vegetables with their shoulder poles,

Businessman sitting behind the counter thinking and scratching his head,

Young-faced, yawning gate guards,

Through the window, Li Ang looked at Chang'an City, which had woken up from sleep, and stretched out his hand, feeling the wind flowing through his fingers.

Squeak.

The carriage stopped outside Pingkang Square,

Li Ang and Qiu Feng jumped out of the carriage and walked straight to the pavilion.

The door on the first floor of the pavilion was ajar, and a doctor from the ward was lying in a temporary bed in the corridor.

Li Ang woke him up, "Give me the medical records of all the patients, and I have prepared the medicine. Give the medicine to the most seriously ill patients first."

"Ah, oh, um."

The doctor in the ward was obviously still asleep, and he was confused for a while before he realized it. He quickly took out a stack of documents from under the pillow and handed it to Li Ang.

Li Ang quickly flipped through the materials. Due to the suggestions he submitted to the Imperial Medical Office, both the Imperial Medical Office and the Chang'an Infirmary have developed the habit of recording detailed medical records.

Suddenly, his fingers froze, "Why are there only forty-three patients? There are two more?"

".this."

The doctor in the ward hesitated for a moment, and said with difficulty: "They are too sick and have already left."

Li Ang's breathing was stagnant, Qiu Feng noticed the expression on his face, and hurriedly asked the doctor in the infirmary, "When did you leave?"

"Three days ago,"

The doctor in the sick room replied: "At first we wanted to inform you, Doctor Li, of the death, but your medicine has reached a critical moment."

Li Ang shook his head, ".It's still too late."

Qiu Feng hesitated for a moment, patted him on the shoulder, and took the document from his hand, "Three days ago, the incident happened suddenly. At that time, there was not even this batch of penicillin suspension. I have tried my best. "

Li Ang pursed his lips slightly, said nothing more, picked up the medicine box, and went to the ward.

In order to prevent impurities in the penicillin, or the patient has an allergic reaction, a skin test, that is, a skin sensitivity test, should be done before using the penicillin.

Li Ang prepared penicillin with normal saline and gave the patient a skin test.

Fortunately, the purity of this batch of penicillin was very high, and none of the patients tested had allergic reactions.

Then came the intravenous infusion, and when the process was over, it began to drizzle outside the window.

Qiu Feng sat on the stool and yawned non-stop. Seeing this, Li Ang said: "There's nothing to do here, we have to wait three or four days to observe the effect, or I'll send you home first. I'll let someone tell you about it at the academy." Let me ask you for two or three days off."

"No, I can still hold it, I can hold it, ah—"

As Qiu Feng spoke, he yawned again, and then nodded embarrassingly.

Li Ang borrowed an oil-paper umbrella from the doctor in the sickroom, walked out of Pingkangfang with Qiu Feng, and walked in Chang'an on a rainy day.

The drizzle is like silk, causing little ripples on the river,

Pedestrians walked with umbrellas, unaware that the two doctors passing by them had just done an epoch-making thing.

"arrive."

Qiu Feng stopped in front of his own mansion in Daningfang, walked out of the umbrella range, hesitated for a moment, turned around, and nodded to Li Ang, "See you at the academy."

"See you at the academy."

Li Ang nodded in agreement, watched Qiu Feng walk into the mansion, his back disappeared, then turned around slowly and stepped into the rain.

He returned to Pingkangfang, and after confirming the condition of the patients receiving intravenous infusion, he went to the darkroom under the leadership of the doctor in the ward, and saw the bodies of the two dead patients.

Knowing Li Ang's habits, the ward used a talisman to store the corpse in cold storage.

Li Ang looked at the patient who had lost the light of life, remained silent, and clenched his fists under his sleeves.

In fact, on the way to Chang'an, he thought about it more than once, to secretly hinder the development of penicillin, so as to prevent the emergence of super drug-resistant bacteria in his lifetime.

Anyway, penicillin is his achievement, neither the academy nor the imperial court can understand or understand the deep meaning of the steps.

He can do some tricks to limit the use of penicillin to a certain range.

However, looking at Qiu Feng, looking at the people in Chang'an city living and working in peace and contentment, looking at the cold corpses of patients before him, he really couldn't make such a decision.

The meaning of medicine is to cure diseases and save lives.

So, be open.

Open the use of penicillin, and before he dies, establish a complete medical system for the country of Yu and the world, to counteract the hidden and invisible enemies.

Li Ang gently pulled up the white cloth, covered the deceased, and stepped out of the room. I recited that oath silently in my heart.

Today I enter the medical profession and take an oath to dedicate myself to humanitarian service;

I am grateful and respect my mentor, just like treating my parents; and practice medicine with conscience and dignity;

The health and life of patients is my primary concern;

I will strictly guard the secrets entrusted to me by patients;

I will do my best to uphold the honor and noble traditions of the medical profession;

I regard colleagues as brothers;

I am responsible for patients without distinction of any religion, nationality, race, politics or status;

Life is the supreme dignity from conception;

Even under threat, my medical knowledge is not contrary to humanity.

I hereby solemnly and independently swear the above oath in my own right.

The last Hippocratic oath does not count
