Li Ang browsed through the information in the memory hall in his mind and continued: "General, have you ever seen anyone who can't eat salt for a long time?"
"Of course I have."
Yan Yundang vaguely guessed what Li Ang was going to say, and nodded: "If you don't eat salt for a long time, your limbs will become weak, your face will look pale, and you will suffer from nausea and vomiting.
No matter how strong a man is, he will become so weak if he doesn't eat salt for a year and a half that he can't mount a horse or lift a knife."
"That's exactly the truth."
Li Ang said: "People must obtain different types of nutrients from food and water every day in order to maintain internal balance.
Once you eat less or cannot eat, you will become weak or even sick."
"Is it balancing yin, yang and five elements, qi, blood and body fluids?"
Yan Lin nodded. As a Xiantian realm warrior, General You Jinwu, he grew up in the army.
What Li Ang said has some similarities with the body refining methods taught in the military, but it is not difficult to understand - in the early stages of body refining, you also need to reuse prescriptions and take medicinal baths.
"Can..."
Yan Lin frowned and said: "The dishes my father eats are all normal, with a balance of meat and vegetables.
During this period, under the doctor’s advice, I stopped drinking alcohol.”
"The food is normal, but the problem with the Duke is in his stomach."
Li Ang said helplessly.
There are two possibilities for Yan Yundang's megaloblastic anemia. One is the lack of folic acid - vitamin b9.
The second is a lack of vitamin b12.
The daily requirement of folic acid is 200 to 400 μg. The human body stores enough folic acid for four months. As long as you consume fresh vegetables every day (overcooking or pickling vegetables will cause the loss of folic acid), there will be no problem.
Vitamin b12, synthesized by natural microorganisms, is the only vitamin that requires the help of an intestinal secretion to be absorbed.
Its storage capacity in the human body is about 2 to 5 mg, and the daily requirement is only 0.5 to 1 μg, and it can be absorbed repeatedly.
Even if you are a vegetarian who does not eat meat, it will take at least 10 to 15 years to develop vitamin B12 deficiency.
Yan Yundang is not a vegetarian or only eats non-vegetarian food.
His recipe is normal,
In other words, regardless of whether his megaloblastic anemia is caused by a lack of vitamin b9 or a lack of vitamin b12 (these two causes can only be identified through blood tests, etc., and there is currently no condition),
There must be problems with his gastrointestinal absorption function!
If there is insufficient folic acid, it means that the intestinal disease affects the absorption of folic acid.
If there is insufficient vitamin B12, it means a lack of intrinsic factor in the gastrointestinal tract, leading to vitamin B12 absorption disorder.
"Suppose a person has something wrong with his body and cannot maintain homeostasis no matter how much salt he eats, then he will become irreversibly weak."
Li Ang said: "Similarly, Duke Yan has a gastrointestinal problem. No matter how balanced he eats, his qi and blood will still become insufficient."
"The triple burner is the path of water and valley, and the place where Qi ends and begins. Does the lower burner need to reduce turbidity, and the middle burner needs to be activated?"
Qiu Zhen on the side murmured to himself.
The lower burner and middle burner he mentioned refers to the "Huangdi Neijing·Lingshu", the chest and abdomen are divided into three areas: upper burner, middle burner, and lower burner. The upper burner above the diaphragm is the upper burner, the stomach is the middle burner, and the lower burner is below the stomach.
.
Li Ang nodded, "Exactly."
"Then what can Dr. Li do?"
Yan Lin pursed her lips tightly, bowed her hands respectfully, and asked seriously.
"The way...it's hard to say."
Li Ang took a deep breath and said slowly: "The temporary solution is to eat more cooked and not overcooked livestock offal, eggs, fish, pears, and various vegetables including Langqiong Zhaobaleng.
Beef, pork, chicken, tofu, etc.
However, the probability that it will eventually be alleviated or even cured is only about 30% to 40%.”
Yan Lin was choked when he heard this, clenched his fists subconsciously, and said in a deep voice: "Why is it only 30%?"
"Gastrointestinal diseases cannot be accumulated in a day or a month."
Li Ang said: "Once the disease becomes diseased, it is extremely difficult to cure."
"Okay Lin'er,"
Yan Yundang interrupted his son who was about to ask more questions, and said slowly: "I, Yan Yundang, have been on the battlefield for more than fifty years.
When I was hungry, I gnawed on rotten horse carcasses, drank mire sewage, and even ate Guanyin soil and even the flesh and blood of demons.
Being able to live to the age of seventy is already a blessing from Haotian.
For organ lesions, 30% is enough to hope for cure.”
He stared at Li Ang deeply and asked: "Doctor Li, if this anemia disease is not cured for a long time, what will happen to me in the end?"
"...pernicious anemia will not directly cause death in the short to medium term,
But if it doesn’t get better, you may continue to have fatigue, drowsiness, numbness in your hands and feet, and jaundice.”
Li Ang whispered: "In the most serious case, it may lead to mental depression or even...insanity."
"Insanity?"
Yan Yun hesitated and then raised his head, a strange smile appeared on his face, "Hahaha, when I was young, my fellow soldiers would always laugh at me as 'Martial Madman', 'Martial Madman',
I never thought that they would all die of old age or in battle, and I would really turn into a lunatic..."
"Father!"
Yan Lin's eyes were red and she choked, but she was greeted by Yan Yundang's stern eyes, "Stand still! What does it look like for a man to cry!"
Yan Lin subconsciously raised her chest and raised her head, standing upright, with the outline of her clenched jaw appearing on her cheeks.
Just like when I was young.
Yan Yundang pursed his lips slightly with mixed emotions, stared at Li Ang and said, "I'd better thank Dr. Li.
At least let me know why I will die."
Li Ang cupped his hands and stopped talking.
In fact, the 30% chance of cure he mentioned is basically folic acid deficiency, which can be alleviated by supplementing large amounts of folic acid.
If Yan Yundang suffers from pernicious anemia due to gastric mucosal atrophy and lack of intrinsic factor in the gastric juice, resulting in vitamin B12 malabsorption...
Then there is absolutely nothing you can do.
Vitamin b12 is a red compound containing cobalt. Its atomic structure is extremely complex, with 181 atoms distributed in a magic felt shape in space.
If you want to artificially synthesize vitamin B12, you need to synthesize the various parts of vitamin B12 first, and then connect them together.
Under the current conditions, it is simply impossible to achieve it.
"Yan Jiu, please go to the warehouse and then deliver it to Dr. Li for me."
Yan Yundang let out a long sigh and raised his hand to ask the old servant butler, who was also choking, to send Li Ang out on his behalf.
The old housekeeper first went to the warehouse, then returned to the hall, and took Li Ang to the side door of the backyard. Qiu Zhen also accompanied him.
When he reached the door, the old housekeeper suddenly stood still and bowed deeply to Li Ang, "Thank you so much, Dr. Li."
"where..."
Li Ang sighed softly, returned the gift, and said hesitantly: "If the Duke's Palace wants to use pigeons to conduct experiments according to my method, it might as well set up a few more groups and feed them bran bark, bran bark mixed with a small amount of sugar, and a small amount of bran bark mixed with a small amount of sugar.
Salt chaff, only feed sugar, etc.
Wait until some pigeons become unwell before feeding them brown rice.
Use this to test whether my statement is correct or not.
As for the Duke's condition, I will go back and check the medical books and think of a solution."
"Thank you, Dr. Li."
The old butler nodded gratefully, took out five Qianguan flying tickets from Liuguang Bank from his arms, and was about to hand them to Li Ang.
"What are you doing, old man?"
Li Ang refused to accept it, but the old housekeeper said: "This is the wish of the Duke, Li Xiaolang, just accept it.
The notice posted by the Duke's Office in Chang'an already stated that any medicine prescribed by a doctor that can alleviate the disease will be rewarded with thousands of dollars.
If I can be cured, I will be rewarded five thousand guan."
After repeated refusals to no avail, Li Ang could only accept a Thousand-Guan flight ticket in the name of relieving his symptoms, got on the vehicle of the Duke's Mansion, and returned to Huaidefang.
————
It was late at night, Li Ang was lying on the bed in the bedroom, looking at the starry sky outside the screen window, his lips slightly pursed.
In the evening, the servants of Duke Yan's Mansion came again and brought over the bay-red horse that had been fostered in the pasture of the academy.
The bay horse is a military horse. After a little relationship building, the Yan family removed the bay horse from the military and gave it to Li Ang. It is currently kept in the stables of the hotel.
This also makes Li Ang's emotions more complicated - the treatment for pernicious anemia is daily oral or intramuscular injection of vitamin b12, and lifelong medication.
However, whether it is artificial synthesis or extraction of vitamin b12 from the fermentation waste liquid of streptomycin, neomycin, chloramphenicol and other antibiotics, mature biochemical technology and modern chemical systems are required.
How difficult it is.
"Time."
Li Ang kept sifting through the many materials in the memory palace, but still felt it was as difficult as climbing to the sky, and couldn't help but sigh.
Chai Cuiqiao, who was already asleep on the bed on the other side of the room, turned over and wondered what she was dreaming about. She muttered and answered: "The times are calling..."
Hey, you girl secretly imitate my normal speech, right?
Li Ang glanced at Chai Cuiqiao, who was wrapped in a ball, laughed dumbly, and shook his head.
The era he refers to refers to the lack of biochemical foundation and chemical industry foundation.
Also refers to... concept.
‘Blood transfusion therapy can theoretically temporarily relieve a small part of the symptoms of pernicious anemia patients.
But it cannot fundamentally treat megaloblastic anemia.
In addition, there is also a question of whether it is effective for Grandmaster level warriors to receive blood from ordinary people, and the risk of blood agglutination must also be considered.
the most important is,
The state of Yu pays attention to the physical, hair, and skin care of its parents.
Would drawing blood from others and transfusing it into the body be considered the same evil behavior as that of the demonic sects of the pre-Sui Dynasty?
Those demons also like to play with blood.’
Li Ang thought silently: 'This is a human being, not a military horse or a pig.
If the news that blood transfusion treatment is effective spreads out, I don’t know how it will be distorted in those remote and backward areas where information is delayed.
There may even be fools who think that drawing blood is equivalent to extracting life and longevity, and that taking other people's blood can extend their own lives, so they take the initiative to harm others...'
Li Ang does not have high expectations for the general medical knowledge of the Yu people - after all, there are always fools who believe that eating the flesh of their relatives can cure tuberculosis and other diseases.
The Academy, only the Academy, can develop the chemical industry that Li Ang wants as soon as possible.
Only with the authority and resources of the Academy can we reduce the possible harm caused by misinformation in the process of promoting medical common sense.
"Calculating the time, it won't be long before the Academy re-examination..."
————
Time passed quickly, and in the blink of an eye it was midsummer in July, the day of the Academy re-examination.
Since only 5,000 students participated in the re-examination this time, the examination location was adjusted to Honglu Temple, Taichang Temple and Sinong Temple within the imperial city walls.
Li Ang stood in the shadow of the imperial city wall, waiting to enter.
Just like last time, the order of candidates' positions was disrupted.
Not far away, Song Shaoyuan looked serious and muttered something, as if he was carrying something.
Zhai Yiming nervously kicked the curb and chatted with Yang Yu, who was also nervous.
Even Ji Linglang, who had always been calm and unhurried, took out the book and took a few glances during the brief interval.
As far as the eye could see, the students who were not nervous at all seemed to only have themselves and He Fanshuang standing in the corner - she stood alone, exuding an indifferent aura that kept strangers away.
Strange to say, given the enthusiasm of the citizens of Chang'an, or the extent of their good deeds,
You should be able to quickly know the specific information of the first place in the academy's preliminary examination, such as place of origin, parents' occupation, family income, etc.
But almost no one knows the information about He Fanshuang - even the fellow villagers from Youzhou who came to apply for the Academy with her have no idea of her identity at all.
"Maybe he comes from somewhere other than Youzhou and deliberately filled in the wrong place of birth information to hide his identity?"
Thoughts flashed through Li Ang's mind,
However, is this necessary?
Disciples of high-ranking nobles with the five surnames would not hide their identities.
Even members of the Li clan entered school under their real names - the clan circle in Chang'an was large or small, and there were always people they knew, so there was no need for that.
"Li, brother Li."
Yong Hongzhong's voice came, Li Ang turned around and saw Yong Hongzhong standing behind him, holding his hands and smiling.
"Oh, Hongzhong."
Li Ang smiled. He didn't like the so-called Le'an Princess very much, but he didn't have any ill intentions towards Yong Hongzhong. "Are you still dizzy recently?"
"No, no more."
Yong Hongzhong said with a smile, "I exercise according to the method you said every day. I won't get sick again."
"That's good. How are you preparing for the retest?"
Li Ang chatted casually with the other party. Yong Hongzhong's grades were quite good, with top grades in policy questions, scriptures, and poems.
But when he was in the imperial examination, he was afraid that his otolithiasis would relapse and fall off the horse, so he didn't dare to speed up at all. He rode slowly and missed the point, so he had to wait for Ding, who was at the bottom.
The overall score was ranked 60th in the last preliminary test.
While the two were chatting,
"Hongzhong."
The sound came from far away, and Li Ang and Yong Hongzhong turned to look, only to see a group of luxuriously dressed Wuling teenagers approaching.
The leader was Qiu Jinghuan, the eldest son of the Minister of Civil Service, who did not see Pei Jing.
"Why are you here? I've been looking for you for a long time."
Qiu Jinghuan patted Yong Hongzhong on the shoulder, turned to look at Li Ang, raised a strange smile at the corner of his mouth, cupped his hands and said: "Yongjiafang, Qiu Jinghuan."
Li Ang cupped his hands and replied calmly, "Zhenzhou Li Ang."
"Hey, it turns out it's Brother Li Ang who came second in the first exam and made a big splash in the Imperial Examination."
Qiu Jinghuan grinned, looked at his companions around him, and deliberately pronounced the word "Li Ang" quickly and into a cool character, "Since Brother Li Ang knows Hong Zhong, he is my friend.
We should all get closer and closer in the future."
"oh."
Li Ang's attitude was still cold, and he was not surprised by Qiu Jinghuan's inexplicable hostility - not only because of the first test, but also because the son of the Minister of Civil Affairs, who was born in Yongjiafang, and the Le'an Princess had been neighbors since childhood.
According to what Bao asked about Yang Yu, Qiu Jinghuan was one of the suitors of Princess Le'an.
"Hachiro, bring the gift here."
Qiu Jinghuan waved, and his companion immediately brought two books.
He took the book and handed it to Li Ang with a smile, "It's a small gift, I hope Brother Li Ang doesn't mind."
The two books are "A Needle Sutra" and "Qianjin Yifang·Forbidden Sutra" respectively. They are antique and the paper is yellowed.
Yong Hongzhong looked at the medical book, his brows furrowed involuntarily, his lips pursed slightly, a little angry.
It is not a secret that Li Ang is a doctor, and Qiu Jinghuan did not mean well when he sent two medical books - "Qianjin Yifang·Forbidden Sutra" records the method of curse and forbidden,
And curse ban... Although it was once an official subject of the Imperial Medical Office,
But in essence, it is primitive witchcraft, which uses dancing, praying, and singing to expel the curse attached to the patient to "cure" the patient.
The method of cursing is a product of ignorance caused by backward medical science. It is a product of the fact that existing medical techniques cannot cure diseases and have to resort to ethereal witchcraft.
Over the past hundred years, as the academy's research on aliens has become more and more profound, the curses and curses derived from primitive religions have also continued to decline and are about to die out - even the Imperial Medical Office plans to cancel the curses and curses.
Qiu Jinghuan sent this book just to ridicule.
If you are not a good appearance, then you are a good doctor. Be a good doctor.
The handsomely dressed young men who followed Qiu Jinghuan chuckled lightly,
And Li Ang...
"hehe."
Li Ang shook his head and smiled. Instead of feeling angry, he felt a little nostalgic and amused.
This is the kind of atmosphere where a boy tries every possible means to attract the attention of a girl he likes, while the companions around him start making fun of him.
Familiar yet strange, close yet distant.
Dang Dang Dang——
The bells of Haotian rang throughout the imperial city. All the scholars raised their heads, put down their books, and entered the examination room under the guidance of officials from the Ministry of Rites and teachers from the academy.
"The medical books are exempted."
Li Ang smiled and waved his hand, ignoring Qiu Jinghuan and everyone, and strode towards the examination room.
This chapter has been completed!
