Beijing, in a laboratory of Daming Medical College.
The elderly professor Zhang Zhigang is conducting experiments in the laboratory with his young grandson Zhang Xingjian.
Zhang Zhigang was one of the earliest professors at Daming Medical College. He taught and educated people in the medical school and researched various medical techniques and drugs for more than 20 years.
At this time, Zhang Zhigang was already nearly 80 years old, but he was still in good health and in good spirits. He was still keen on researching various medical technologies and teaching people here.
Although he has already reached the age of retirement and should have gone home to recuperate, he could not stay idle. He worked as a doctor all his life, suffered from illnesses all his life, and also worked as a professor here for more than 20 years and taught many students.
.
If people are really free, he really can't stay idle, so he doesn't need any money and continues to teach people at Daming Medical College for free, imparting his rich medical knowledge and experience.
In Daming Medical College, he has always been very respected and loved by everyone. Both teachers and students in the school affectionately call him old professor.
Zhang Zhigang devoted a lot of new knowledge to Ming Medical College and taught many famous doctors. His students are all over Ming Dynasty and even around the world, and many of them are famous doctors in various places.
Of course, he also attaches great importance to his family.
The Zhang family practiced medicine during their time, and this is still the case today. All his descendants are doctors who practice medicine. Basically, the younger generation of descendants have entered Daming Medical College to study various medicines.
Although this grandson Zhang Xingjian is only 18 years old, he has studied medicine with the old professor for many years. He especially likes to study and study bacteria and virology, and he likes to use microscopes to observe the microscopic world.
"Grandpa, there's mold all over this container."
Zhang Xingjian was preparing to take a look at the bacteria he had cultivated as usual. When he saw what was inside container No. 16, he immediately shouted out in surprise.
"Yeah, let me take a look."
When Zhang Zhigang heard this, he also walked over tremblingly.
Let’s take a look at my little grandson first. Zhang Xingjian is a typical Chinese and Western mixed race. His father is from the Ming Dynasty. As for the current one, he is a white slave from Europe.
Originally it was just bought by the Zhang family and used as a slave. One time, Zhang Xingjian's father came back from drinking and killed his mother directly, and thus Zhang Xingjian was born.
Because his father's lineage has always given birth to daughters, and he is the only son, Zhang Xingjian, so even though he was born as a slave, Zhang Xingjian has been highly valued since he was a child, and his mother also changed from a slave to a concubine.
Status has been improved.
Zhang Xingjian has black, straight oriental black hair, but his eyes are as deep as sapphires, his nose is high, his skin is fair, his body is tall, and his face looks more like a Ming Dynasty person. You can tell at a glance that he is of mixed race.
Mixed-race children like Zhang Xingjian are very common now, especially in the Beijing-Tianjin area, where people have high living standards and high incomes, so they buy white European slaves as concubines. The practice of servitude is very popular, so there are a large number of mixed-race children.
Although they are mixed-race children, they are also descendants of the Ming people. The people of the Ming Dynasty have never treated these mixed-race children as outsiders. They have always treated them as their own descendants.
For example, Zhang Xingjian, although he is of mixed race, his grandfather, his father, and even his uncles and uncles are very kind to him. He has been highly valued since he was a child. In addition, he is smart and studious, and he is deeply loved by his grandfather Zhang Zhigang.
Because of his age, Zhang Zhigang was in good spirits and condition, but his body was no longer good and his whole body was trembling.
Zhang Xingjian looked at his grandfather and recalled it carefully in his mind.
This No. 16 vessel seems to have happened some time ago because my grandfather suddenly fainted while he was in the laboratory, and then he hurriedly sent him for treatment. Then he happened to meet the annual medical school visit period again.
I went to some rural free clinics in Shanxi with many classmates.
As a result, it was delayed for more than 20 days. Unexpectedly, because I was too anxious at the time, I forgot to close the lid, and everything turned out to be moldy and covered with long blue hairs.
"It's all moldy, so throw it away."
Zhang Zhigang looked at the moldy utensils. They were almost like moldy tofu, with a layer of green hair growing on them.
"Hmm~"
Zhang Xingjian nodded and was about to throw the container away. After thinking about it, he put it under the microscope and took a closer look.
"The amount of streptococci inside has been greatly reduced, and the closer the blue mold is, the smaller the number of streptococci. Could it be said that this kind of green mold can cause damage to streptococci, or can it greatly kill streptococci?
"
Zhang Xingjian became energetic.
Zhang Xingjian has been studying streptococci and mycobacteria for a long time. The reason why he wanted to study this thing was because Zhang Xingjian was studying medicine with his grandfather. During his medical practice, he saw many people dying due to untreated tuberculosis, so he thought about it.
Can I develop new medical techniques or drugs to treat this tuberculosis?
At this time, tuberculosis was an incurable disease with no treatment at all. The mortality rate was almost 100%, and the disease was also contagious.
Not only were there a large number of patients in the Ming Dynasty, but also in Zhang Xingjian's current hometown in Europe, tuberculosis was very popular, especially among the nobles, where many people suffered from tuberculosis.
People suffering from tuberculosis are thin and pale, and only have short-term flushing in the afternoon. Therefore, in Europe, many nobles are proud of having this disease. This is an aristocratic disease. Some people want to get this disease.
disease, and even come into contact with people who have tuberculosis.
"Grandpa, the germs in the container seem to have been killed. This green mold seems to be able to kill streptococci and mycobacteria."
Zhang Xingjian shouted excitedly.
"What?"
When Zhang Zhigang heard this, he was also slightly startled.
He has been practicing medicine all his life and is a professor at Daming Medical College. He has also created many new medical fields and has in-depth research on bacteria and virology.
He knew very well what the germs his grandson was studying were the bacteria and viruses that caused tuberculosis and wound infections.
In his many years of medical practice, Zhang Zhigang has seen many people die from tuberculosis. Tuberculosis is a disease that cannot be cured at all.
Zhang Zhigang still supports Sun Tzu's idea of studying this disease, but he doesn't think he can research anything.
For thousands of years, not only the doctors of the Ming Dynasty were helpless, but even Europe, Tianzhu, Ottoman, Africa and other places did not have any medical skills or drugs that could treat this disease.
However, this disease spreads very widely, and many people die from tuberculosis. A large number of people die from tuberculosis every year.
Zhang Zhigang came over tremblingly and observed carefully through the microscope.
"It seems that a lot of them have been killed. The closer you are to this green mold, the smaller the number of streptococci and mycobacteria."
After Zhang Zhigang finished observing, he nodded and said.
"Grandpa, can we do experiments with these cyan molds alone to see if it can really be used to kill these bacteria?"
Zhang Xingjian thought for a while and said.
"Well, you can try it, maybe it really works."
Zhang Zhigang nodded and said.
If this cyan mold can really kill streptococci and mycobacteria, it means that it can most likely be used to treat tuberculosis, which will be a major breakthrough.
In the future, tuberculosis may no longer be an incurable disease, but a curable disease.
"yes!"
When Zhang Xingjian heard this, he became more energetic and quickly started to take action.
Carefully separate the blue mold in the container, and then put it into a container with a large number of streptococci and mycobacteria.
The next day, Zhang Xingjian came to the laboratory again for observation.
“It really works!”
"This green mold can kill most streptococci and mycobacteria. These streptococci and mycobacteria seem to have been dissolved."
After taking a closer look through the microscope, Zhang Xingjian couldn't help shouting excitedly. It's really effective. This means that this cyan mold can most likely be used to treat tuberculosis, and this will be a bacterial, virological
A major leap and progress, this achievement is enough to prove the huge role of bacteria and virology.
At the same time, this also means that tuberculosis, a disease that has plagued mankind for thousands of years, will usher in its own nemesis. From now on, tuberculosis can also be cured.
Zhang Xingjian hurriedly found his grandfather Zhang Zhigang and shared the good news with him.
"Is it really effective?"
Zhang Zhigang was extremely excited when he heard it. It seemed that this green mold could really be used to treat tuberculosis.
"You purify some of this blue mold, and then try it on people suffering from tuberculosis."
After thinking about it, Zhang Zhigang also gave instructions.
During this period, the management in this area was naturally not as strict and standardized as that of later generations. The use of many new drugs and treatments can be carried out at any time as long as both parties agree, and there are not so many steps, procedures and the like.
.
Even for the launch and sale of new drugs, there are no excessive steps, procedures, etc., because the government has very loose control over this aspect, and it can even be said that there is no control at all.
This is not within the responsibilities of the imperial court, not to mention that as long as it is to cure diseases and save people, these are nothing. This is also one of the reasons why many new drugs and new medical techniques at Daming Medical College are developing extremely quickly.
