Chapter 251 Master and Apprentice
Everything is here.
Looking around at the raw materials and equipment in the room, Li Ang took a deep breath and raised his palm to release his thoughts.
Potassium antimony tartrate, also known as tartaric acid, is a potent emetic and antiparasitic drug.
It can disturb the belt of schistosome worms, causing them to lose the muscle adsorption function, fall off from the blood vessel wall, be carried by the blood flow to the liver, and be eliminated by the human immune system in the liver.
In addition, antimony potassium tartrate can also affect the energy supply of worms, affect the reproductive system of worms, and has a strong killing effect on schistosomes and filarials.
"First, Antimony"
Antimony is called Lianxi in Yu State, and it was used to mix copper with it to mint currency.
The antimony shipped from Tanzhou is of high purity.
After calcination, antimony white can be obtained, that is, antimony trioxide.
"And then, tartar."
The tartar precipitated in wine contains about 50% to about 85% potassium hydrogen tartrate. After hydrochloric acid decomposition and recrystallization, potassium hydrogen tartrate with higher purity is obtained.
"A mix of both."
Put potassium hydrogen tartrate and antimony trioxide in a weight ratio of 2:1 into a round bottom flask, add distilled water, install an air condenser,
Using talismans and thoughts, simulate a constant temperature magnetic stirrer, heat in a water bath, and control the temperature close to boiling.
After the antimony trioxide is basically dissolved, filter while hot,
The obtained filtrate was concentrated by evaporation, cooled and crystallized, and allowed to stand.
Subsequently, wash with a small amount of high-concentration ethanol, and dry at a temperature of eighty degrees,
Finally, white crystals were obtained.
“.”
Li Ang looked at the extremely pure antimony potassium tartrate, but there was not much joy in his eyes.
He silently picked up the medicine, diluted it with 5% glucose injection, walked out of the secret room, went to the shed outside the hospital, and injected a small amount of antimony potassium tartrate to a sick cow infected with schistosomiasis.
Then take out the Niansi, penetrate into the body of the sick cow, and monitor the physical condition of the sick cow.
He told Qiu Feng and others that he wanted to develop medicines, so don’t bother him if there is nothing particularly important, so the courtyard was extremely quiet, only the hard panting of the cattle.
After an unknown amount of time, Niansi finally got feedback.
In the body of the sick cow, one after another schistosome twitched and shrank, fell off the inner wall of the blood vessel, was rushed to the liver by blood, and was surrounded and killed by inflammatory tissue in the liver.
Countless pharmacists and prescriptions were helpless against schistosomiasis, facing the special drug antimony potassium tartrate, they had no resistance at all, and were killed one by one by the autumn wind like fallen leaves.
Li Ang still didn't have much joy on his face.
He got up and walked across the courtyard, pushed open the courtyard door, and looked up at the overcast sky.
succeeded,
However, the price is too great.
——
Taihu Lake was called Zhenze in ancient times, also known as Lize.
It is the beginning of spring at this time, the lake is rippling, and the willow trees on the bank are sprouting, swaying with the wind,
The spring breeze is warm, the grass is green, and the air is filled with the fragrance of grass and trees.
"Everyone must wear socks and gloves before going into the water! Do you hear me?"
"Be careful, schistosomes are pervasive, even exist in the dew on the grass blades, even if you feel hot, you can't take off your gloves!"
"Ditches, every old ditch must be covered, and new ones must be dug! Don't think that digging other people's ditches has nothing to do with you. After the spring plowing starts, the ditch water system will be connected. If the snails in one place are not completely wiped out, a large area of cultivated land around them will be destroyed. To suffer!"
On the banks of the river, countless mobilized people wielded shovels and hoes, struggling to dig ditches.
If the snails and schistosomiasis cannot be killed on a large scale before spring plowing, all states, counties, towns and towns along the Taihu Lake will suffer from a new round of water poisoning disease.
Gululu—
A carriage passed by on the lakeside road,
"Hehe. This momentum is really fighting against heaven and earth. Man will conquer heaven."
His gaze swept across the sweaty people on the bank, and a strange smile appeared on his face, "Yu Shi, do you know why I want to spread the disease in Yu Country?"
"Um?"
The white-haired boy sitting on the opposite side of the carriage thought that this was another test from the teacher, so he thought about his words and slowly replied, "In order to defeat the State of Yu?"
"No, defeating Yu State is Zhao Ming's goal, not ours."
Situ Zhi said, "Think again."
"for."
The young man named Yu Shi followed the teacher's gaze and looked at the people of Yu country outside the window, hesitantly replied: "Observe the reaction of the people under the epidemic?"
"It's close."
Situ Zhi smiled and said: "We spread the disease not to kill as many people as possible, but to observe the strength of people.
You are an abandoned baby of Western descent that I picked up,
In our hometown, the Far West, there used to be a great empire named Romulus.
Romulus' territory and number of people are no less than that of Yu State. Romulus' scholars, like the academy, advocate the way of reason.
Five hundred years ago, an unprecedented plague broke out on Romulus,
Sick people have severe diarrhea, vomiting, sore throat, fever, thirst, ulcers on hands and feet, pus on the skin, and rashes on their bodies that peel off like fish scales.
From the royal family and nobles to the slaves and civilians, nearly ten million people died in the plague, the entire empire was hit hard, the order was crumbling, and the fire of civilization was almost extinguished. "
Situ Zhi said leisurely: "However, just when everyone thought that the Romulus Empire would perish and perish, the disease subsided.
The living people who stand up from the pile of dead bodies will no longer be infected with diseases, and the population will rebound accordingly.
They cleaned up the corners of the city, built better public buildings, farming and construction within the empire were more developed than in the past, all places had roads through them, and every city was open to business.
People reclaimed wasteland, built manors, cut down thorny forests and replaced them with farmland.
The civilization of the empire is also more prosperous than in the past,
The death of the slave master freed a large number of slaves,
Past debts are wiped out, business is re-established and thriving,
The college lowered the threshold and admitted more students,
The nobles are afraid of the power in the dark, and dare not act recklessly. The depravity, luxury and **** of the upper class of the society is abolished,
Even the seemingly endless war had to be suspended due to lack of manpower.
A terrible plague brought rebirth to the empire. "
Situ Zhi said with emotion: "In the East, everything is the same.
The newly-born kingdom, because it cleared up the past evils, was able to re-establish order and quickly possess a strong national power.
For example, the Han Empire, from when Han Gaozu was besieged by the Xiongnu at Baideng Mountain to when Emperor Wu of the Han attacked the Huns and forced them to move to Mobei, it took only a few decades.
After the fall of the Western Han Dynasty and Emperor Guangwu once again ruled the world, the population of the empire increased again, and the national strength quickly recovered.
Until the end of the Eastern Han Dynasty, the empire was unable to suppress the Yellow Turban Uprising due to decay, and decided to drink poison to quench thirst, and ordered the counties to recruit soldiers on their own, which eventually led to the demise of the Eastern Han Dynasty. "
He stroked his beard and said with a smile: "The destruction of a great empire is often not due to the invasion of foreign enemies.
But before that, the empire itself fell into a long period of ossification.
The aristocrats are high above the top, the rich and wealthy wantonly annexed the land, the rich are connected with fields, and the poor have no place to stand.
Scholars who aspire to change the status quo are forced to get involved in officialdom and lose their motivation in the intrigue.
The interests of all parties are like cobwebs covering every corner of the empire. Everyone knows that the status quo is wrong, but no one has the ability to change it.
The only lesson humans can learn from history is that humans never learn from history.
Unlike some people in Zhaomingli, I don’t hate Yu Guo,
On the contrary, I have a good impression of this huge empire that is somewhat similar to Romulus. If it weren't for the limitation of my status, I would actually like to go to the academy and discuss it with the doctor there.
And I did not spread this plague to destroy them,
It's more like...a kind reminder, a wake-up call. "
