In Würzburg, Roentgen continued to study X-rays.

Immediately after returning to Berlin, Johann sent five of his previously recruited physicists to the University of Würzburg, where they would work on X-rays with Roentgen. The difference is that Roentgen will focus his main energy and time on the X-rays themselves, while the five men, after a short period of study, will try to study the technical improvements that John describes as making X-rays clearer, more accessible, and safer.

In this respect, the purposes of John and Roentgen are fundamentally different.

John himself wasn't much interested in physics, and he didn't want to act too demonic, so he simply made an investment and got his hands on the future X-ray machine patent. When he returned to Berlin, he quickly turned his attention to his original job.

It has to be said that it was really not difficult to promote the development of medicine at the end of the 19th century.

A month is short and almost negligible for future medical research, but for John at the end of the 19th century? For Huntelaar, whichever piece is chosen, it is enough.

To put it bluntly, this is the absolute leading edge of the times.

For example, an electric light bulb, as long as you learn how it works, any high school student can make it; Another example is the bicycle, which Chinese born in the 20th century does not know its structure and working principle? So a 21st-century surgeon goes back to 1888, and he doesn't need to be like Liszt, 20 years of hard work is to find a better way to sterilize, and he doesn't need to spend years or even more than a dozen years dissecting hundreds of corpses like Bierrot to find a way to open the stomach for stomach cancer, and the mortality rate of patients is still frighteningly high!

So......

One month was enough time for John to perfect the equipment and technology needed for indirect blood transfusion. Teach Howard? Kelly, let the obstetrician-gynecologist start experimenting with the poor puppies; A month is enough time to teach two surgeons all the basic techniques of Heinz surgery, and then let them make frequent attempts on animals; One month is also enough for the technicians of Heinz Pharmaceutical Company to master the preparation and purification methods of diphtheria serum antitoxin, and start to produce the first finished product that can be used for clinical trials.

So when John returned to Berlin. In September 1888, the next step began......

……

At the same time, Java, Indonesia.

Since the Dutch first arrived on the island 300 years ago, it has become a world of Westerners, and although there was a brief period of British rule in between, it was a Dutch paradise for the most part. The implementation of cultivation value turned the natives into slaves of the Dutch, and the miserable life does not need to be repeated.

But for Europeans. It's a matter of course.

No matter how loud the colonizers' slogans were, they could never hide the fact that they were bright red. However, for most Europeans, this kind of thing really does not interest them, and under the propaganda of the mainstream newspapers, they only laugh at the barbarism and backwardness of the natives, and hail the benefits of colonization to the country, and never care about the bloody facts. Just like Liszt, who talked to John about this without changing his face, in their opinion. Civilized Europeans occupied the lands of the indigenous barbarians of the East, oppressing them for profit.

Christian. Ackerman. is also one of them.

The future Nobel laureate, who at this time was an ordinary military doctor, was working with a team sent by the Dutch government to study the headache of beriberi.

For the Dutch military doctors of the 19th century, beriberi was a very strange and frustrating disease. There is no obvious cause for the onset of this disease, but in severe cases, it can cause muscle weakness. Fatigue, palpitations, shortness of breath, and so on, are enough to make a strong soldier incapacitated, and can also make a hardworking slave lose his last worth. For has been completely declined. For the Dutch, who had almost no political or military status in Europe, the importance of the colonies in Southeast Asia was self-evident, so beriberi became one of the most important enemies of the Dutch kingdom.

Christian. Aikman is part of a research team sent by the Dutch government to Java to solve this problem.

Conducting medical research in a place like Java is undoubtedly a very painful thing, and Aikman lacks the appropriate equipment and utensils, as well as the lack of truly high-quality collaborators, and everything can only be carried out in a difficult groping. Soon after, the top graduate of the University of Amsterdam was discharged from the army due to malaria. But after retiring, Aikmann did not give up the study of beriberi, but went to Germany. Professor Koch studied bacteriology under him and then returned to Java the year before to continue his research on beriberi.

The current mainstream thinking naturally believes that beriberi is caused by a bacterium.

On the one hand, the rapid development of bacteriology provides a theoretical basis, and many bacteriologists even shouted the slogan that all diseases are caused by a certain bacteria, so the Dutch naturally put forward a hypothesis, that is, beriberi bacteria cause beriberi; On the other hand, whether it is Pasteur or Koch, the study of bacteria has made them gain a huge reputation, and the British Liszt is now also advocating disinfection technology to kill bacteria, the prestige is increasing day by day, so the study of bacteria at the end of the 19th century can bring great prestige and benefits to researchers.

Aikman's work in Java is dedicated to discovering the bacteria that causes beriberi.

It's just that all the efforts have changed more than a few months ago, and a letter from the European continent made Aikman completely change his research ideas after thinking deeply!

With the help of his colleagues, Aikman first conducted a series of animal experiments, that is, a group of chickens. He found that chickens would have severe symptoms of beriberi if they only ate white rice, but feeding them grain mixed with bran would alleviate these symptoms! This strange phenomenon immediately confirmed the argument in the letter, and it also lifted Ekman's spirits, and he soon extended his black hand to the prisoners......

People in prison are not qualified to talk about human rights.

Intent on finding the cause of beriberi, Aikman didn't even think about why the indigenous prisoners were imprisoned, and with the help of the prison guards, he forced them into two groups, one eating only white rice every day, and the other eating brown rice, and patiently observed their performance.

It didn't take long for the results to come out.

Prisoners who ate brown rice were far less likely to develop beriberi than prisoners who ate white rice, that is, the argument in that letter was correct, brown rice did contain a substance that could alleviate or even cure beriberi. What Mr. Huntelaar called vitamins!

Agitated, Aikman immediately wrote his research into a paper and sent it back to distant Europe...... (To be continued......)
