Chapter 641 Mr. Zhao who is dedicated to serving the people

Previous page        Return to Catalog        Next page

    Li Lunming was the top surgical expert in the Ming Dynasty, and he was extremely skilled in his skills.

    After Zhao Hao introduced the method of preparing slices, he used a special knife to cut the snail meat into thin slices, placed them firmly on a glass slide, and then covered them with precious coverslips.

    It¡¯s like it has been tested for many years, as stable as an old dog.

    After a while, the only thirty wave carriers were all used up.  To maximize coverage and accuracy, thirty sections were taken from five different snails.

    As luck would have it, evil-looking schistosomiasis larvae were found on three of the slices.

    This convinced the three doctors that there were indeed parasites in the snails.

    How to determine whether the larvae are the pathogenic schistosomiasis?  There was no need for Zhao Hao to mention the 'Koch's Principle'. The three of them immediately came up with the experimental method based on your words.

    First, the larvae are cultured and grown in a glass petri dish.  Then, adult worms visible to the naked eye are found from the sick animals. If the comparison is consistent, Zhao Hao's conclusion is correct.

    The age-old mystery of the cause of schistosomiasis has been 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 progressed, which is holding back doctors.

    He is very much looking forward to where these awesome medical scientists will take Ming medicine with the help of science.

    ??~~

    After seeing the disgusting larvae, the three doctors were still not satisfied and asked Zhao Hao what those ubiquitous 'little poles' and 'little curly hairs' were.

    Zhao Hao said with a vicissitudes of life: "Those are bacteria."

    "Bacteria?" Li Shizhen got 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 disease?" Li Shizhen held a small notebook and looked at Zhao Hao with curiosity.

    ¡° Thinking that he could add a rich and colorful touch to the "Compendium of Materia Medica", he felt that his decision to come to Kunshan couldn't be more correct.

    Zhao Hao was confused by the questions and felt that he needed to write "Creature" as soon as possible.

    But writing textbooks for students is very troublesome for me. Hey, will my hairline recede if this continues?

    ¡®I¡¯m still a child, I shouldn¡¯t have to shoulder so much¡¯ Mr. Zhao secretly whined, but he could only patiently explain to Li Shizhen and the others:

    "Bacteria, like animals and plants, are also a type of living things. They are everywhere and come in many types But they can be roughly divided into three types in terms of shape. Those 'little sticks' you see are various bacilli and 'little curly hairs'  It¡¯s all kinds of spirobacteria. And also all kinds of ¡®cocci¡¯.¡±

    "Bacteria are so invisible, but they affect our lives all the time. Without the help of bacteria, we would not be able to digest food, ferment food, etc. But many bacteria can also cause food rot, wound suppuration, and sudden illness of humans and animals.  . Hundreds of diseases, such as colds, tuberculosis and plague, are caused by these harmful bacteria."

    Zhao Hao picked up a bottle of alcohol, sucked a drop with a straw, dropped it on the petri dish and said: "But there is no need to talk about discoloration. Using this alcohol can kill most bacteria."

    "So when we do experiments, we must first take precautions. After the experiments, we must strictly follow the rules for cleaning and disinfection. In the same way, strict disinfection must be done in the hospital, which can greatly increase the survival rate of patients."

    This is another new concept that the three doctors have never heard of.  Are all these diseases caused by tiny little things?  It's simply unimaginable.

    But with the trump card of the microscope, they will no longer question Zhao Hao easily.

    After the three famous doctors thought about it, Mr. Zhao must have invented the microscope for many years and used it to conduct long-term research before reaching this conclusion.

    Although people cannot be superstitious about authority, it is ridiculous ignorance to question areas that they do not understand without any basis.

    ¡®With the help of microscopes, we can naturally verify all this.  ¡¯ The three of them said silently in their hearts.

    In fact, at this moment, they already understood that Zhao Hao opened the door to a new world for himself and Ming medicine.

    The three doctors are full of hope, hoping that this new world can solve the mysteries that have troubled them for many years.

    Now there is no need for Zhao Hao to keep people around. He can¡¯t be beaten away even with a stick.

    So they readily agreed to Mr. Zhao¡¯s invitation to help him run the first hospital in the Ming Dynasty.

    ? ?However, Zhao Hao must provide sufficient support to ensure their research.

    This is what Mr. Zhao hopes to see, and the two parties will naturally conclude the deal happily.

    Only Zhao Shizhen knew that this microscope had only been built less than half a month ago, and his uncle had never seen it a few times.

    ¡°Hey, others invent for the sake of exploration, but my uncle seemed to do it to prove that his own ideas are correct.

    Hey, what does it mean to be born aware?  What is Niu Boyi?  What does it mean to look at someone who is not like a mortal?

    It¡¯s my uncle you¡¯re talking about

    ??~~

    After coming out of Jiangnan Hospital, Zhao Hao rushed to the embankment again.

    Although it was already dark, the torches on the embankment illuminated the sky, and there were still people busy all night long.

    That was Zhang Jian directing the craftsmen, debugging the installed lifting device.

    Starting tomorrow, the stones will be delivered continuously.  Engineers can only work overtime to avoid affecting the progress of tomorrow's project.

    Craftsmen have known about using the principles of levers and pulleys to lift heavy objects two thousand years ago. This is explained in detail in the "Mo Jing".

    The windlass on the well is the most intuitive embodiment.

    The lifting device at this time is no different in principle from the water puller. It is just more load-bearing and more labor-saving.

    With this thing, the stones in the rattan baskets do not even need to be unloaded from the ship, and can be hung directly on the deck with iron hooks.

    The workers did not need to go down to the river, they could just stand on the earth embankment and shake the winch, and they could easily lift the stone weighing two hundred kilograms up the embankment.

    Then they worked together to move the rattan basket to the crane installed on the other side of the embankment, hoisted it down the embankment, and landed directly on the cart on the inside of the embankment.

    The workers can then directly pull the stones to the new embankment ten feet away.

    In fact, Zhang Jian also invented a crane that can turn its head, which can greatly save labor on the embankment.

    "It's a pity that Kunshan's backward blacksmiths can't make cast iron sleeves and inner shafts that meet the specifications. The craftsmen from the Ordnance Bureau are about the same.

    But it is still time-consuming and labor-intensive, and the gain outweighs the loss.

    Zhao Hao asked Zhang Jian to improve and optimize the existing wooden crane and make do with it.

    Not efficient enough?  Then just install a few more units. Just install a pair within a mile.

    Anyway, there is free labor, and even if the tools are a bit inferior, it will not affect the progress.

    This once again proves that cheap and abundant labor is the main culprit hindering the technological progress of Ming Dynasty.

    "But Mr. Zhao is also very helpless. Ming Dynasty's two to three billion farmers need to eat, and this is the overriding priority.

    ????????????????????????????????????????????????????????????????????????????????????????????????????????

    So those who keep saying that Mr. Zhao is a capitalist can stop.

    Capitalists can use machines but never people!  Only a patriotic industrialist like Mr. Zhao would take the initiative to tie his own hands and feet for the sake of the well-being of the people.

    When I think about it, I feel that I am great.

    ¡°Well, it¡¯s not that he can¡¯t make it.
