"In addition, the officers and soldiers sent by the imperial court to exterminate the robbers may also prey on the common people, which is a side effect of Western medicine."

"In addition, if the villagers do not deal with the officers and soldiers, they will anger the officers and soldiers. The officers and soldiers sent by the imperial court to exterminate the robbers may also be killed along with the villagers, which is the death of the patient caused by allergies to Western medicine. ”

"Uh-huh." The crowd nodded incessantly.

Qin Yu spoke too easily to understand, and there were almost no people who couldn't understand it.

"In addition, there is another benefit of Chinese medicine." Qin Yu said, "When the villagers learn martial arts and learn to use knives and guns, they will become stronger, and they will not be afraid of robbers in the future, which is called improving immunity." ”

"Traditional Chinese medicine is the study of nature and the use of plants in nature to cure diseases, and people originally live in nature, so it is more in line with the laws of natural survival. Western medicine, on the other hand, uses chemical reactions to create drugs that are not available in nature, and treats diseases under visual instruments, respecting scientific and technological facts. ”

"Makes sense!" The crowd said.

"Alright, let's get to know the bacteria now." Qin Yu said, "Chinese medicine is not aware of the existence of bacteria at all, because there is no microscope. Therefore, in this regard, Chinese medicine lags much behind Western medicine. ”

"So when dealing with bandit gangs with fierce temperaments, large numbers, and more advanced weapons. It is simply too late to teach the villagers to practice martial arts and give them swords and guns, and they must rely on the imperial court to send elite officers and soldiers to strangle them. If there is no strong slaughter, the villagers will be slaughtered. ”

"And penicillin is undoubtedly a group of the most elite officers and soldiers."

"So the question is, how do you make penicillin from the soil method?" Qin Yu said, "During World War II, because of the lack of resources, the Japanese encouraged the people to make penicillin in large quantities. It can be seen that the feasibility of this method is still good. ”

"First of all, penicillium is extracted from moldy objects. For example, oranges, cucumbers, etc., preferably cantaloupe. After Qin Yu finished speaking, he also turned around and wrote down on the blackboard for the students to record.

And the students did not disappoint him, not only listened carefully, but also recorded them all in their notebooks.

"The amount of material used to grow Penicillium is very large, because it is possible to extract a suitable Penicillium species after at least dozens, if not hundreds, of tests."

"The second step is to mix the boiled juice with grains, high-starch potatoes, and rice broth to make a solution of the culture medium."

"The third step is to put Penicillium in the medium."

"After a week, we can extract the active ingredients from the propagated Penicillium."

"At the same time as penicillium, a bacterium called staphylococcus was extracted from the patient and used to test the efficacy of penicillin."

"A week later, the fourth step will be carried out. First, the culture liquid is filtered in a funnel, and then vegetable oil is injected into the filtered liquid and stirred in a wooden barrel, so that the liquid in the barrel is divided into three layers. ”

"Take the bottom layer of water and set it aside, and that layer of water is water with penicillin."

"The next step is to remove impurities from the penicillin-containing water. The fifth step is to inject the penicillin solution into the detoxified toner, stir again, and the toner will absorb the penicillin. ”

"When you put the toner in a container and pour it into boiled pure distilled water, the impurities will be washed out."

"Next, pour in acidic water made of vinegar, penicillin is a weak acid, will not melt in acidic water, this step, is to further remove alkaline impurities."

"Then pour in alkaline soda so that the penicillin dissolves in the toner."

"And then what comes out is a higher purity penicillin solution."

"The last step is the testing step, which is to pour the penicillin solution into a staphylococcal petri dish, close the lid and wait for a few days. If there is no change, the penicillin solution has not been successful. ”

"On the contrary, if there are circles around the dropping solution, it means that penicillin has dispersed staphylococcus, which means that the culture liquid has been successfully made."

"Penicillin solution can be purified again with sterilized rice paper."

"The prepared penicillin solution is applied to rice paper, hung vertically, and the end is immersed in the acid dialkali eight solution. Using on-paper chromatography, high-purity penicillin is refined by layering on paper. ”

"Note that a skin test must be performed before it can be given to a patient. As for the skin test, it is to inject a little bit under the skin and watch the experimenter's reaction. ”

Qin Yu was talking on the top, and the students were concentrating on the record below.

Even Zhu Yuanzhang and Queen Ma joined the ranks.

At this time, there were only two voices in the classroom, Qin Yu's voice and the sound of students writing.

Because they were all written with a brush, almost everyone wrote down a dozen pieces of blank paper.

"Alright, I'm done." Finally, after Qin Yu finished teaching, he finally said in conclusion, "Penicillin is the greatest drug invention of the twentieth century, especially in war. ”

"Some wounded soldiers can easily die from a bacterial infection, and penicillin is the best medicine to treat the infection."

"During World War II, penicillin saved tens of millions of lives. As a result, the life span of human beings has been extended by fifteen years. ”

"Saved tens of millions of people? The human life span extends to fifteen years! The crowd was shocked. Although this medicine has the risk of allergies, it is definitely a miracle medicine from the perspective of saving tens of millions of people and extending the life span of human beings for fifteen years.

There is nothing to doubt!

"In addition, although the method I taught you is an earth method, it has also undergone several purification operations." Qin Yu also said, "Its effect has been verified by the Japanese people during World War II, and it is not much worse than that refined by high technology." ”

"It can be said that it is already the best folk method."

"If the village chief has ambition and enough energy, he should strictly follow this method."

"Aspiring? We're so ambitious. Zhu Yuanzhang said in his heart.

For the sake of our sister, no matter how hard it is, we have to make penicillin.

Penicillin can not only save our sisters, but also wounded soldiers and other people infected by bacteria.

If you don't do such a miracle medicine against the sky, you will not be a qualified emperor.

In addition, we have enough energy, and we don't do it ourselves, there are hundreds of imperial doctors in the palace.

……

After taking classes for so long, the morning was over in no time.

Qin Yu announced the end of class.

Originally, Emperor Zhu still had a lot of questions to ask Qin Yu, such as Hu Weiyong, and corrupt officials who couldn't finish cutting questions, but the most important thing at the moment was to make a miracle medicine that could save his sister.

Therefore, the questions he wanted to ask could only be saved for next time.

Soon, the two walked out of the village.
