Chapter 151 One Heart for the People, Young Master Zhao
Li Lunming was the top surgical expert in the Ming Dynasty, and his hands were perfect.
I heard Zhao Hao introduce the method of slice preparation. He cut the snail into slices as thin as a cicada wing with a special knife, steadily placed it on the slide, and then covered it with a precious coverslip.
It's like an old dog doing experiments for many years.
Not long after, all the only thirty carrier plates were used up. In order to ensure coverage and accuracy as much as possible, the thirty slices came from five different screws.
The result was good luck, and there were all three of them that were found such evil schistosomiae.
This made the three doctors finally believe that there were indeed parasites in the snails.
How to determine that this larvae is a disease-causing schistosomiasis? There is no need to mention the "Koch principle" at all. The three of them immediately thought of the experimental method just by saying everything.
First, larvae are grown in a glass Petri dish. Then, adults that are visible to the naked eye are found from the sick animal. The consistent comparison shows that Zhao Hao’s conclusion is correct.
The eternal mystery of the cause of schistosomiasis was completely solved.
This made Zhao Hao secretly sigh that our medical scientists are actually the best. At least in this era, our medicine is much more advanced than the West. It’s just that our science has not made any progress, which has dragged the doctors down.
He is very much looking forward to these awesome medical scientists, where will they bring the medicine of the Ming Dynasty with the help of science?

After seeing the disgusting larvae, the three doctors were still unsatisfied and asked Zhao Hao what those ubiquitous "little poles" and "little curly hairs" were.
Zhao Hao said in a vicissitudes of life: "That's a bacteria."
"Bacteria?" Li Shizhen was excited again and quickly drew those strange lines on the paper. "Is it also a type of microorganism?"
"Not bad." Zhao Hao nodded.
"So... can bacteria also cause diseases?" Li Shizhen held the small notebook and looked at Zhao Hao with a desire to learn.
Thinking of adding another highlight to "Compendium of Materia Medica", he felt that his decision to come to Kunshan was really correct.
However, Zhao Hao was asked so much that he felt that he needed to write "Bio" as soon as possible.
But it’s very troublesome for me to just write textbooks for students. Oh, will my hairline move backward if this continues?
'I am still a child, and I shouldn't have shouldered so much...' Mr. Zhao whined secretly, but he could only explain to Li Shizhen and the other two patiently:
"Bacteria, like animals and plants, are also a kind of organisms. They are everywhere and have a variety of species... But in terms of shape, the 'little sticks' you see are various bacilli, and the 'little curls' are various spiral bacteria. In addition, there are various 'cocci'."
"Bacteria are so invisible, but they affect our lives all the time. Without the help of bacteria, we cannot digest food, ferment food, etc. But many bacteria can also cause food to rot, wounds to become suppurated, and people and animals to suddenly get sick. Hundreds of diseases such as colds, tuberculosis and plague, etc., are caused by these harmful bacteria."
Zhao Hao picked up a bottle of alcohol, sucked a drop with a straw, and dripped it on the Petri dish, saying, "But there is no need to talk about it and change the color. Use this alcohol to kill most bacteria."
"So when we do experiments, we must take good protection first. After the experiments, we must clean and disinfect according to the rules. By the same token, we must also strictly disinfect in the hospital, which can greatly increase the survival rate of patients."
This is another new concept that three doctors have never heard of. Are those evil diseases caused by these extremely subtle things? It is simply unimaginable.
But with the ace of microscope, they no longer easily question Zhao Hao.
Thinking of the three famous doctors, Mr. Zhao must have been using the microscope for many years and used it for a long time to come to this conclusion.
Although people cannot be superstitious about authority, questioning the areas they do not understand without any basis is ridiculous ignorance.
‘With the help of a microscope, we can naturally verify all this.’ The three of them said silently.
In fact, at this moment, they already understood that Zhao Hao had opened the door to a new world for himself and the medicine of the Ming Dynasty.
The three doctors were full of hope, hoping that this new world could solve the puzzles that had plagued them for many years.
Now Zhao Hao doesn’t need to keep anyone anymore, and he can’t even beat him with a stick.
So they happily agreed to Mr. Zhao's invitation and helped him manage the first hospital in the Ming Dynasty.
Of course, Zhao Hao needs to provide sufficient support to ensure their research.
This is also what Mr. Zhao hopes to see, and both sides will naturally have a happy deal.
Only Zhao Shizhen knew that this microscope was actually made less than half a month ago, and my uncle hadn't looked at it a few times.
Alas, others invented it for exploration, but my uncle seemed to be to prove it and prove that his own ideas were so correct.
Alas, what does it mean to know by birth? What does it mean to be Niu Boyi? What does it mean to look down on others but not like ordinary people?
I'm talking about uncle...

After leaving Jiangnan Hospital, Zhao Hao rushed to the embankment again.
Although it was dark, the torches on the earthen embankment shone on the sky, and there were still people busy all night.
That was Zhang Jian directing the craftsmen to debug the installed lifting device.
Starting tomorrow, stones will be delivered continuously. Engineers can only work overtime to avoid affecting tomorrow's project progress.
Craftsmen knew to use the principles of lever and pulley to lift heavy objects two thousand years ago, and the "Mo Jing" explained this in detail.
The wheels on the well are the most intuitive manifestation.
The lifting device at this time is no different from the water-filled wheel in principle. It is nothing more than just being able to bear loads and save more effort.
With this thing, the stones installed in the rattan basket don’t even need to be unloaded, and iron hooks are hung on the deck directly.
The villagers didn't have to go down to the river and stood on the earth embankment and shake the winch, and could easily lift the stone weighing about 200 kilograms onto the embankment.
Then work together to move the rattan basket to the crane installed on the other side of the earth embankment, lift it down from the embankment, and land directly on the truck inside the embankment.
The civil servants can directly pull the stones to the new embankment ten feet away.
In fact, Zhang Jian also invented a crane that can turn the head, which can greatly save labor on the dike.
Unfortunately, with the backward blacksmith level of Kunshan, it is impossible to create cast iron sleeves and inner shafts that meet the specifications. It is almost the same as those of the craftsmen in the Military Arts Bureau.
But it is still time-consuming and labor-intensive, and the gain is not worth the loss.
Zhao Hao asked Zhang Jian to improve and optimize the existing wooden crane first, and just use it as you please.
Not efficient enough? Then just build a few more units. You can only install a pair of them in one mile.
Anyway, some laborers are not expensive, and their tools are a little worse, and they will not affect the progress.
This once again proves that cheap and abundant labor is the culprit that hinders the technological progress of Ming Dynasty.
But Mr. Zhao was also helpless. Two or three hundred million farmers in the Ming Dynasty had to eat, which was the top priority that overwhelmed everything.
Is it necessary to rashly engage in industrialization and replace people with machines to make the people rebel?
So those who say that Mr. Zhao is a capitalist can stop.
Capitalists can use machines and never use people! Only a patriotic and loving industrialist like Mr. Zhao will take the initiative to tie his hands and feet for the welfare of the people.
Just think about it and feel that I am great.
Well, it's not that he can't make it.
Chapter completed!
