Daming Town Haiwang

Chapter 2068, penicillin
In Beijing, in a laboratory of Daming Medical College.

The elderly professor Zhang Zhigang is doing experiments in the laboratory with his young grandson Zhang Xingjian.

Zhang Zhigang is one of the earliest professors of Daming Medical College. He has been teaching and educating people, researching various medical techniques and medicines in the medical school for more than 20 years.

At this time, Zhang Zhigang was already nearly 80 years old, but his body was still very good, his mental state was also very good, and he was still keen on researching various medical technologies and teaching people here.

Although he has already reached the age of retirement, he should have gone home to recuperate, but he can't stay idle. He has been a doctor all his life, and he has been sick all his life. He has been a professor here for more than 20 years and taught many students. .

If he really wants to be free, he really can't be free, so he doesn't need money, and continues to teach people here at Daming Medical College for free, imparting his rich medical knowledge and experience.

In this Daming Medical College, he has always been very respected and loved by others. Whether it is the teachers or students in the school, they all kindly call him the old professor.

Zhang Zhigang contributed a lot of new learning to Daming Medical College, and taught many famous doctors. The students are all over Daming and even all over the world, and many of them are famous doctors from all over the world.

Of course, he also attaches great importance to his own family.

The Zhang family practiced medicine in the era, and it is the same now. All his descendants are doctors who practice medicine. The descendants of the younger generation basically entered the Daming Medical College to study various medicines.

Although the little grandson Zhang Xingjian is only [-] years old, he has studied medicine with the old professor for many years. He especially likes to study and study bacteria and virology, and likes to use a microscope to observe the microscopic world.

"Grandpa, mold is growing all over this vessel."

As usual, Zhang Xingjian was going to have a look at the bacteria he had cultivated. When he saw the situation inside No. 16 container, he immediately shouted out in surprise.

"Yeah, let me see."

When Zhang Zhigang heard this, he walked over tremblingly.

Let's take a look at my little grandson first, Zhang Xingjian is a typical mixed Chinese and Western, his father is from Ming Dynasty, and currently he is a white slave from Europe.

Originally, it was only bought by Zhang's family and used as a slave. Once Zhang Xingjian's father came back from drinking, he directly ordered his mother to do it, so Zhang Xingjian was born.

Because his father's lineage has always given birth to daughters, and only Zhang Xingjian is his son, so although he was born to a slave, Zhang Xingjian has been valued since childhood, and even his mother has changed from a slave to a concubine. The status has been improved.

Zhang Xingjian has black, straight oriental black hair, but deep-set eyes like sapphires, a straight nose, fair skin, tall stature, and looks more like a Daming man, so he is a mixed race.

Mixed-race children like Zhang Xingjian are very common now, especially in the Beijing-Tianjin area, where people's living standards are high and their income is high, so buying European white slaves as concubines and slaves is very popular, so there are a large number of mixed-race children.

Although they are of mixed race, they are also descendants of Daming people, and Daming people never treat these mixed races as outsiders, they always treat them as their own descendants.

Like Zhang Xingjian, although he is of mixed race, his grandfather, father, and even his uncles treated him very well.

Due to his age, Zhang Zhigang was in good spirits and in good condition, but his body was already failing, and his whole body was trembling.

Zhang Xingjian on the side looked at his grandfather, and carefully recalled it in his mind.

This container No. 16 seems to be some time ago, because the grandfather suddenly fainted in the laboratory, and then I hurriedly sent him for treatment, and then I just happened to meet the annual outpatient period of the medical school, I went to some rural free clinics in Shanxi with many classmates.

As a result, it was delayed for more than 20 days. I didn't expect that because I was too anxious at the time, I forgot to cover the lid, and all of them were moldy and covered with long blue hairs.

"It's moldy, throw it away."

Zhang Zhigang looked at the moldy utensils, they were almost like moldy tofu, with a layer of long blue hairs.

"Hmm~"

Zhang Xingjian nodded, and was about to throw the vessel away, but after thinking about it, he put it under the microscope for a closer look.

"The streptococci in it have been greatly reduced, and the closer the blue mold is, the less the number of streptococci is. Could it be said that this blue mold can damage the streptococcus, or can greatly kill the streptococcus? "

Zhang Xingjian was in high spirits.

For a long time, Zhang Xingjian has been studying streptococcus and mycobacterium. The reason why he wanted to study this thing was because Zhang Xingjian saw many people died of tuberculosis while studying and practicing medicine with his grandfather, so he thought about it. Can I research new medical techniques or medicines to treat this tuberculosis?

Tuberculosis was an incurable disease that could not be cured at all at this time, and the mortality rate was almost [-]%. Moreover, the disease was contagious.

Not only are there a large number of patients in Daming, but also in Zhang Xingjian's current hometown of Europe, tuberculosis is very prevalent, especially among the nobles, there are many people suffering from tuberculosis.

People who suffer from tuberculosis are thin and pale, and only have a short flush in the afternoon. Therefore, in Europe, many nobles are proud of having this disease. This is a noble disease. Some people want to get this disease disease, and even come into contact with consumptive people.

"Grandpa, the germs in the container seem to be killed. This blue mold seems to be able to kill streptococcus and mycobacteria."

Zhang Xingjian shouted excitedly.

"what?"

When Zhang Zhigang heard this, he was also slightly taken aback.

He has been practicing medicine all his life, and he is also a professor of Daming Medical College. He has also created many new medical fields, and has deep research on bacteria and virology.

He knows exactly what the germs his grandson is studying are the bacteria and viruses that cause tuberculosis and wound infections.

In the process of practicing medicine for many years, Zhang Zhigang has seen many, many people die because of tuberculosis, which is a disease that cannot be cured at all.

Zhang Zhigang still supported his grandson's idea of ​​researching this disease, but he didn't think he would be able to research anything.

It has been thousands of years, not only the doctors in Ming Dynasty are helpless, even Europe, Tianzhu, Ottoman, Africa and other places do not have any medical skills and medicines to treat this disease.

However, the spread of this disease is very extensive, and many people die of tuberculosis, and a large number of people die of tuberculosis every year.

Zhang Zhigang came over tremblingly, and observed carefully through the microscope.

"It seems that a lot has been killed. The closer to the blue mold, the less the number of streptococci and mycobacteria."

After Zhang Zhigang finished observing, he also nodded and said.

"Grandpa, can we do experiments with these blue 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 will really work."

Zhang Zhigang nodded and said.

If this cyan mold can really kill streptococcus and mycobacteria, it means that it is very likely to be used to treat tuberculosis, which will be a major breakthrough.

This tuberculosis may no longer be an incurable disease, but a disease that can be cured.

"Yes!"

When Zhang Xingjian heard this, he regained his energy and quickly started to act.

Carefully separate out the blue mold in the container, and then re-get it into a container with a large number of streptococci and mycobacteria.

The next day, when Zhang Xingjian came to the laboratory again for observation.

"It really works!"

"The blue mold kills most of the strep and mycobacteria, which seem to be dissolved."

Taking a closer look through the microscope, Zhang Xingjian couldn't help shouting excitedly, it's really effective, which means that this kind of blue mold is very likely to be used to treat tuberculosis, and this will be the basis of bacteria and virology. A major leap and progress, this achievement is enough to prove the great 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 then on, tuberculosis can also be cured.

Zhang Xingjian hurriedly found his grandfather Zhang Zhigang and shared the good news with him.

"It really works?"

Zhang Zhigang was very excited when he heard it. It seems that this blue mold can really be used to treat tuberculosis.

"You purify some of this blue mold, and try it on a consumptive man."

After thinking about it, Zhang Zhigang also gave orders.

In this period, the management in this area is naturally not as strict and standardized as the later generations. The use of many new drugs and treatment methods can be carried out at any time as long as both parties agree. There are not so many steps and procedures. .

Even the marketing and sales of new drugs, there are not too many steps and procedures, because the imperial court has very loose control on this aspect, and it can even be said that there is no control.

This is not within the responsibility of the imperial court, let alone as long as it is for the purpose of curing diseases and saving lives, these are nothing. This is also one of the reasons why many new medicines and new medical techniques at Daming Medical College are developing extremely fast.

This is a more rough era!
