Late at night, Li Yuan sat alone in the hut, staring at the candlelight in a daze. It has been more than an hour since the Taoist priests "removing diseases" for his son Li Shimin. No news has been heard.

The Taoist priests did not allow him and his wife to enter the yard, so Li Yuan did not know how his son was.

Normally, Li Yuan’s last hope lies with these Taoist priests. At this moment, he really wanted to burn incense and pray, but there were only Buddha statues in the mansion, so he was a little embarrassed.

Most powerful families believe in Buddhism, and the Li family is no exception. Li Yuan’s eldest son Li Jiancheng, whose small name is called "Vishaman". Now that the family believes in Buddhism, they have to rely on Taoist priests to save their lives. The strong contrast makes Li Yuan not know what to say.

The footsteps sounded, and he looked up, but saw his wife Dou walking in.

Li Yuan said, "Why aren't you sleeping yet? Just keep it here with me."

"I can't sleep, come and accompany my husband and Erlang." After Dou said that, he sat beside Li Yuan. The two of them fell silent and the atmosphere became a little subtle.

After the initial panic, Dou was much calmer, thinking about the various behaviors of his husband after he came back, as well as the visits of those Taoists, which made her feel that there was something very important.

Dou guessed that it was very likely that after his husband entered the palace, he would ask the emperor for permission and send a doctor to see Erlang.

But in order to avoid people's eyes and ears, Li Yuan came back and said that the emperor had no good prescriptions, and the doctor sent by the emperor came to visit him as a Taoist priest in You Fang, and used the excuse of "opportunity" to treat the disease.

If this guess is correct, it means that the emperor's doctor may be confident that he will cure the "pneumonia". In order to avoid trouble, he said he was powerless on the surface and secretly cured the disease.

Li Yuan cooperated with the acting.

Dou really wanted to ask Li Yuan if it was what she thought, but as a smart person, she knew that sometimes it would be better to pretend to be confused.

If the emperor's doctor really has good medicine to treat lung diseases, it should be promoted like "sacne", and even opens a pharmacy shop and sells medicine to make a profit, but now it seems that it is not. Dou thinks that it is because there are too few good medicines, so...

Priority is given to ensuring the needs of the palace, and it is not advisable for too many people to know. Otherwise, one or two kneels in front of the palace gate and asks for medicine to help their lives, and the emperor will find it difficult to do it.

All of this was Dou's guess. She sat with Li Yuan for a while, and there were only her and her husband in the room. As a result, Li Yuan remained silent. She knew that if she asked, it would only make it difficult for her husband to do.

Or, are you thinking too much?

While Dou was in a state of confusion, Li Yuan gently held his right hand. She looked at her husband and held the other person's hand in her right hand.

"It's okay, Erlang will definitely be fine..." Li Yuan said softly, Dou nodded and leaned his head against the other party's shoulder.

The two of them just sat there, staring at the candlelight in a daze.

......

In the room, the young Li Shimin still had a high fever, and the doctors pretending to be Taoist priests were still busy. One Taoist priest (doctor) kept changing the towels for him to apply his forehead, and another doctor wiped his body with warm water to cool it down, and then measured his body temperature every half an hour.

When a patient has a high fever, he must cool down in time, otherwise the high fever will last too long and his brain will be burned even if he does not die.

To cool down, you need to use cold water, apply to your forehead, and wipe your body. However, for young children, wiping your body with cold water will aggravate the condition, so you need to use warm water to dissipate some heat.

This is the experience accumulated by doctors over the years of practice in medicine. When young children are sick, they will rely extremely on relatives or familiar people. Therefore, the two maids who usually serve Li Shimin are waiting outside, come in at any time to feed Li Erlang water, or help him out and change clothes.

Li Shimin, who was suffering from fever, was still very high at this time, but his body temperature had not increased again and dropped slightly.

However, if the lesions are not removed, the high fever will definitely not subside. With his young body, he can't last long. If he continues like this, even if he does not lose consciousness, he will be exhausted due to his inability to eat and die.

In this case, doctors have seen a lot of cases that pneumonia is basically incurable unless it is injected with magical penicillin.

The premise is that you can pass the "skin test" and there is no serious allergic reaction.

Lv Wenhua, who led the team, looked at the boy on the couch and shook his head: The person is beyond help.

The penicillin they brought came in different batches of products, and all of them were tested for skin tests on the patients. The results of skin tests were all allergic, but the difference was the difference between the severity of the allergic.

This means that if the child in front of him is injected with full dose of penicillin, theoretically 99% of the probability of dying from severe penicillin allergy.

If penicillin is not injected, young children will die of pneumonia.

Lu Wenhua looked at the beautiful child and sighed in his heart: Born in a wealthy family, but he has no blessings to live. The child will join another good family in the next life.

Now that things have come, the second phase of the experiment can be started.

Tonight, Lu Wenhua and his party called Save People, but in fact they are still conducting clinical trials. Now people cannot be saved, but the trials still have to continue.

He wiped his sweat with a hand towel and asked, "Which numbered product is the mildest allergy symptoms?"

The person next to him who was responsible for taking the record replied: "Penicillin No. 17."

"Very well, inject the full dose, and then take the pulse every half hour and take the body temperature once..."

"yes."

At the beginning of the second phase of the experiment, a doctor injected Li Shimin with a full dose of penicillin product (Product No. 17), and then everyone took turns to observe.

They injected full-dose penicillin into young children, deliberately causing allergies, and then observed various symptoms of the patient's death to accumulate clinical trial data.

Cruel is a bit cruel, so what?

Over the years, countless seriously ill patients have died in the clinical trial of penicillin. The son of the Duke of Tang is just a calculation molecule among the huge numbers.

For Lu Wenhua and his colleagues, one general's success is a waste of thousands of bones. In order to study penicillin, it is nothing to use the dying person to do experiments.

According to the new medical theory, the reason why a patient gets sick is that "germs" or "viruses" are rampant in the body. One of the symptoms is a high fever, so only by finding ways to kill the "germs" or "viruses" in the human body can the patient be cured.

Penicillin is an extract extract from Penicillium. It is said that the bactericidal effect is very good and can be used to treat diseases.

The principle sounds simple, but it is difficult to do. Since the Xiyang period, Lu Wenhua and other doctors and experimenters have been working hard to study how to extract effective penicillin, but the progress has not been satisfactory.

The research took many years and consumed a lot of manpower, material resources and financial resources. They finally found a set of methods that could extract slightly effective penicillin and enter the "clinical trial" stage.

However, such penicillin cannot be used directly on patients.

The problem lies in purification. If there are too many impurities in the purified penicillin, the patient will die due to severe allergies after injection.

Therefore, before injecting penicillin, subcutaneous tests should be conducted to see if the patient is allergic to the penicillin to be injected. This is called "skin test".

Because it is impossible to effectively purify the penicillin products, the rate of penicillin passing through the skin test in humans is very low. Even if the patient passes the skin test, the probability of penicillin taking effect will still be very low.

Because with the current technical level, the "penicillin" extracted from different penicillin substances are unknown.

In short, even with penicillin products, the probability of patients survival is very low, so penicillin products extracted according to current technology have no practical significance at all.

The emperor invested heavily in the research of penicillin, which was far away from the breakthrough. However, if you were willing to plant flowers and flowers, you would not bloom, and if you were unintentionally planted willows and willows, you would turn into shady willows. The colony culture technology derived from the research was converted into fermented tofu and could actually make a profit.

Since then, Lu Wenhua and his colleagues have continued to work hard, and penicillin extraction technology has made some progress and can be changed to veterinary medicine.

A workshop in Chang'an has always had the ability to mass produce penicillin products, but these so-called "penicillin" are all medicines prepared for pig farms and chicken farms, specifically used to treat swine fever and chicken plague.

Especially for treating chicken plague, large chicken farms are prone to chicken plague because of the large number of chickens and the dense chicken cages. Once they die, they will be a large area. With the magical "veterinary medicine", the owners of the farm have at least a half-percent chance of stop loss.

It is precisely because of this that when Lu Wenhua received the order from the emperor, he could immediately take out many prepared penicillin products. Although these penicillin products were intended for use as veterinary medicine, they could still be used to rescue people in emergency situations.

But now, patients are allergic to all the penicillin they bring, and there is no possibility of pneumonia curing, so it is better to "use waste".

Lu Wenhua and his colleagues have experienced a large number of clinical experiments. After witnessing one patient after another injected with penicillin, they hoped to recover with their families, but died suddenly.

If you see this kind of scene too much, you will become numb, so everyone will be able to develop a heart that will not make you feel sad or feel guilty.

Even if success is nowhere near, clinical trials will never stop.

When they entered the mansion, they had already made it clear to Duke Tang that the probability of rescuing the patient this time was less than 10%. Life and death are alive, and the other party agreed, so there was nothing to worry about.

It’s not that no one has recovered after injecting penicillin products, but it is obvious that Li Erlang is not one of the lucky ones.

Before I knew it, Dongfang was white. Three hours had passed since the full dose injection. The sixth temperature measurement ended. Lu Wenhua and his colleagues looked at the measurement results and were stunned.

After the first five measurements, the patient still had a high fever, and his body temperature dropped from 41 degrees to about 39 degrees, and now...

The body temperature was 37 and a half degrees, and it was the case after retesting twice.

Looking at the patient who had subsided and had sweat again, Lu Wenhua exchanged glances with his colleagues, and each saw a surprise from each other's eyes: Is it effective?

Someone murmured: "How is it possible... a person who can't pass the skin test, how can he..."

"Quick, hurry! Prepare to take samples immediately, take samples immediately!" Lu Wenhua shouted in a low voice, and the others quickly opened the portable ice magazine (a wooden box with ice cubes), took out the test tubes, glass dishes and other utensils, and began to prepare for sampling.

"Tongular coating, nasal snot, phlegm, all of them are taken and taken back!"
