Song Yang kept the extracted penicillin-dissolved water, and today's work was over.
The next day, he started new experimental steps.
Boiled and sterilized activated carbon, a separation tube with a large opening at the upper end and a small opening at the lower end.
There is also vinegar as acidic water, and alkaline water filtered by plant ash precipitation.
Now add activated carbon to the penicillin-dissolved water and stir thoroughly. The activated carbon will absorb the penicillin in it.
Then put the activated carbon into the separation tube and clean it with distilled water.
Then inject acidic water.
Finally, inject alkaline water.
At this time, add filter cotton to the lower outlet to reduce the flow rate.
At this time, what drips out of the separation tube is penicillin with a relatively high concentration.
This work has been busy for three days.
The first day was waiting for Gongsun Mo to bake the separation tube.
The next day, Song Yang accidentally dropped a box of petri dishes.
The work on the third day went well, and penicillin with unknown effects was finally prepared...
"Your Majesty...is this the magic medicine?"
"It looks like a decoction, but why is it transparent? Is it water?"
"The residue of the medicine has been filtered out? Is this effective?"
"It shouldn't be painful, right?"
Shen Xiaowan and Tong Qian started to comment on the penicillin in the test tube.
Song Yang guarded the penicillin very dearly, for fear that the two girls would be damaged.
"This thing is penicillin. It looks transparent but is actually a medicine. Just like... salt water looks transparent but is actually salty!"
"Is this salty?"
"No! I have no time! I have no time to talk nonsense with you!"
Song Yang kept the penicillin speechlessly.
Then he pulled the two girls out of the laboratory.
"Where to go?" Tong Qian let Song Yang pull her and asked curiously.
Shen Xiaowan knew that Song Yang pulled them out in a hurry because something was wrong.
"Find the target of the experimental drug!" Song Yang said as he walked.
"Who should be allowed to experiment?" Tong Qian asked again.
"Could he be a wounded soldier who returned from Dangtu?" Shen Xiaowan whispered.
"How could it be used on Taoists without animal testing?" Song Yang said angrily.
"Let's go catch mice!" Song Yang said solemnly.
"ah!"
"Help!"
"Let go! Prince, don't pull me! I won't catch the mouse!"
Both Tong Qian and Shen Xiaowan screamed...
Song Yang's eardrums hurt so much...
"Haha! Don't you really want to know how to experiment with penicillin? Why are you so scared?" Song Yang teased.
"Then we just want to know how to conduct experiments! We don't know how to conduct experiments on mice!" Tong Qian emphasized.
"Hmm. We don't want to catch mice. Your Majesty, you'd better find someone else to do it!" Shen Xiaowan said timidly.
Big rat, long tail, ugly.
How can a serious girl not be afraid?
"Haha! Okay then. I'm going to catch mice then! I'll come back and show you the mice in a while!" Song Yang laughed and walked out.
"No! I won't watch!" the two girls said in unison.
Penicillin is about to enter the stage of animal testing.
Song Yang didn't have any white mice, so he had to use domestic mice.
White mice are a variant of the house mouse.
It has been specially cultivated.
At this stage, we can only deal with mice first, and then slowly breed white mice.
"Catch mice?"
"Your Majesty, the health of our new city is a political priority. Rats are hard to find now..."
Song Yang said he wanted to catch mice, but Fang Zhe looked confused.
After natural disasters, especially after the epidemic, health supervision in Jiangzhou Fucheng has risen to a stringent level.
All domestic waste must be landfilled in a centralized manner.
There are garbage trucks in the city every day to take away domestic garbage.
Moreover, there are staff who specialize in cleaning up snakes, insects, rats, and ants in the city and patrol them every day.
It’s really hard to find rats in the city...
"There are some over there in the garbage dump. What do you want rats to do?" Yu Ming asked curiously.
"Do experiments. I have researched a new drug and need mice for experiments."
"In the future, we need to specially breed some mice for experiments. This thing is low-cost, easy to cultivate, and we won't feel bad if we die."
Song Yang talked about the uses and benefits of mice.
Yu Ming seemed to understand, but Song Yang wanted to find mice, so he took over the matter and immediately went to the garbage dump with a few guards.
Yu Ming went to catch mice, while Song Yang went to see the wounded soldiers.
The attack on Tanzhou and Suzhou resulted in a total of 436 wounded soldiers.
However, there were only thirty-seven wounds with inflammation.
It’s not that the probability of inflammation is low, but that the serious cases before were not cured.
The symptoms of these thirty-seven people were relatively mild, and most of them have recovered after being treated by Dr. Lu.
Only two people were in serious condition, with constant fever for unknown reasons.
Doctor Lu only said that external evil entering the body caused the wound to suppurate.
Song Yang knew that their wounds were infected.
Penicillin may be effective.
"Doctor Lu, how long can these two brothers survive?" Song Yang pulled Lu Jimin into the corner and asked.
"If it doesn't get better... half a month at most!" Lu Jimin frowned.
This situation has often been encountered before.
Infections can only be fought off by one's own immunity.
The decoction also replenishes energy, but the direct anti-inflammatory effect is not obvious.
Moreover, the extremely powerful doctors in Jiangzhou are not experts in this field.
"Doctor Lu, we must delay it as much as possible! Penicillin has been trial-produced and will be tested on animals soon."
Song Yang informed Lu Jimin of the good news.
Lu Jimin knew that Song Yang was working on penicillin.
Lu Jimin couldn't help with this, but he believed in Song Yang and the efficacy of penicillin.
"Great, with this anti-infective drug, these two people can be saved. When will penicillin be available to people?" Lu Jimin said happily.
"It's hard to say. You have to make sure the animals are fine before they can be used by humans." Song Yang shook his head.
"Okay. I'll try my best to delay these two little brothers." Lu Jimin nodded.
There are also animal experiments on drugs in Chinese medicine.
For example, when Lu Jimin first learned bone setting, he did experiments on animals.
So he also understood that medicines must be given to animals first, and then to people.
In the afternoon, Yu Ming came back with two wooden boxes in his hands.
"My lord, I caught twenty of them!" Yu Ming said with a smile on his face.
"Let me take a look." Song Yang carefully opened the lid of the box.
The little mice were hiding in the corner and shivering.
"Hmm. Not bad. Give it to me." The wooden box turned out to be very satisfying.
"Let people pay more attention in the future. If there are white mice, they must be caught." Song Yang warned.
Yu Ming responded hurriedly.
From then on, there was a team of ten people near the garbage dump, specifically looking for rats.
I heard that those who are not white will not be arrested!
The common people are spreading rumors that the white mouse has become a spirit, and the prince wants to capture the mouse spirit for sacrifice...
And Song Yang certainly doesn't care what the people say now.
He went into the laboratory and started his little mouse experiment...
In order to infect the mice with bacteria to meet experimental standards.
Song Yang can only defeat the rat with ruthless hands.
They were scratched, and then the scratched mice were locked up alone to wait for their wounds to become infected.
There is still time left, and in this hot weather, wounds are still relatively easy to get infected.
But this also takes time.
Song Yang also wants to hurry up, but unfortunately there is no other way now.
Of course, he didn't just wait.
While waiting for the mice to be infected, Song Yang prepared some penicillin liquid.
If the mouse experiment is successful, it can be used immediately on the two infected brothers.
"Your Majesty! Don't come here! Go take a bath first!"
Song Yang was disliked as soon as he came home after a busy day.
The two girls disliked Song Yang's close contact with the mouse and did not dare to let him get close.
Song Yang had no choice but to change and wash before entering the house...
The majestic prince was actually disliked by two little girls.
Really abominable!
Song Yang could only use family methods against him.
Recently, Song Tong has always come around and tried to make Song Yang work harder.
Moreover, he encouraged the two girls to attack Song Yang.
Song Yang was tired of dealing with it every day.
Fortunately, his body has been transformed through time travel and is quite strong.
Otherwise, I would have collapsed from exhaustion...
On September 28, the injured mice in the laboratory finally showed symptoms of infection.
Two of the mice developed fever and vomiting symptoms.
Obvious suppuration can be seen in the wound, and the surrounding skin is swollen.
Another day of waiting.
This disease is more obvious.
Song Yang felt that it was almost done, and immediately injected penicillin into one of the mice.
The injection needle was jointly made by Song Yangran Wang Blacksmith and Gongsun Mo.
Glass needle tube, stainless steel needle.
Just one syringe took three days.
Of course, this needle is big enough for an elephant, let alone a mouse...
So the first experiment ended in failure as expected.
The mouse convulsed and died less than half an hour after being injected with penicillin.
Song Yang scratched his head and initially estimated that the measurement was too large.
The syringe is so big that there is no way to mark one milliliter.
The amount of medicine in the needle alone exceeds one milliliter...
Song Yang took the medicine according to his feelings, but the result was that the little mouse collapsed in one fell swoop.
The first one died, and now the pressure is on the second little mouse.
It doesn't know yet that the shackles of fate are coming.
This time Song Yang reduced the dosage again, and half of the penicillin that did not reach the needle penetrated the mouse's body.
The mouse with a big needle hole twisted wildly.
The needle's eye... was bleeding...
However, under Song Yang's pressure, the bleeding point quickly stopped.
All that's left is to wait.
Song Yang looked back and saw Lu Jimin and Li Rui standing outside the window.
They both came to see Song Yang's experiment.
However, they were not given protective clothing for the experiment.
Moreover, these two people were only allowed to observe, so they did not enter the laboratory and only stood outside the glass window and watched.
"Wait. We'll see the results later." Song Yang said.
The first mouse died just now. Lu Jimin shook his head. He thought Song Yang might have stabbed the little mouse to death with that big needle...
"Mr. Lu, do you think the prince can succeed?" Li Rui asked in a low voice.
"Probably... yes." Lu Jimin wasn't sure either.
Then he added: "Even if it fails this time, it will definitely succeed in the future. What the prince said has never been missed."
"Well. That's true. I hope it can succeed. Those two brothers probably won't last long."
A few days ago, Lu Jimin said that the two infected wounded soldiers could last at most half a month.
Ten days have passed now.
And the condition of the two wounded soldiers worsened further.
Song Yang also knew this situation and couldn't wait to start the experiment.
