"Infectious diseases have always been the focus of medical research, with countless pathogens of various types. All internal and surgical departments have noticed that it is in this field that determines the clinical outcomes and life and death of countless patients, so there has been a pursuit of anti-infective drugs since ancient times.
"The ancestor Fleming took Penicillium tangerine peel and took intravenous medicine for only three days. The patient's fever subsided and his blood was stable. Less than twenty years later, it was also in the soil that Shatz was isolated from his master Waxman to obtain streptomycin to treat negative bacteria and tuberculosis, with significant results.
"I don't understand why everyone is talking about traditional palliative therapy, as if this anti-infective drug is destined to be a place where medicine will fail. A year ago, I went south from Wendeng Port and started research on instruments and pharmaceuticals. The second of the three major elements of surgery was conquered. On the day the diagnosis and treatment plan was updated, all the patients and colleagues were happy, and they were well-known in the place and people.
"That kind of vitality and the state of competition for everything is still in front of you. Is it true that after all the funds in the venue have changed, and it will become an unbreakable dilemma?
"No matter how you say it, the equipment gap can be made up with other means, and the advantage lies in me!"
...
"Ah? Where is my bacteria?"
The former Monastery Warehouse No. 2 is now a closed laboratory of the Knights.
Craft's hand holding the glass petri dish trembled slightly, and the high cost of the vessel effectively suppressed the tremor amplitude and frequency.
Fortunately, it was not the first time. A few days ago, the Knight Commander, who had not waited for an abnormal situation to break out, finally sorted out daily affairs to a certain extent and generously divided the most closed and independent area of ​​the monastery.
The part that originally belonged to the private property warehouse at the top of the monastery has now become a laboratory for placing glass and crystal instruments that may be of higher value.
With the dazzling array of instruments filled with wooden racks, the idea of ​​not wanting to be idle and falling into dust comes, and new ideas will naturally become active.
The inspiration may be from the mold spots seen on the peels in wet weather. The next day's purchase list added a large number of various meats, fish glue, bones, wheat flour, and refined salt.
With a relatively simple biological experiment level and sufficient cooking knowledge, a thick soup that will turn into a gel after cooling is born, rich in ingredients that both microorganisms and multicellular organisms love.
Then he scraped the target mold colonies, sprinkled them into the Petri dish, and finished sowing. At that time, he was already worried about how to complete the organic solvent extraction based on current conditions.
However, subsequent developments have proved that the extraction may be a bit too far away for worrying about it.
The cultivation cannot be said to be unsuccessful, it can only be said to have not succeeded in the direction of hope.
To put it more comfortably, at least the culture medium is well produced and the results are relatively artistic.
The rich colors that grow vigorously inside remind you that there is a high degree of similarity between the local and Westminberg microecological environments.
If an artist is here, he will surely inspire him. He will spend a lot of precious paint and make a rare painting that will make Kupp wake up at midnight after watching it.
Fortunately, there are no artists here, nor Kupp.
The latter has already led the team down the mountain. I don’t know what the situation is, and it is estimated that it will be difficult to make much progress in the short term.
CRASTE is willing to trust him, and the assistant has enough experience in preliminary investigations, being cautious and knowing how to advance and retreat.
From a negative perspective, it may seem a little cowardly, but for the work he may take on in the future, knowing when to retreat to the three miles is more important than meaningless courage.
There are certainly times when there are misjudgments, but there is no need to worry too much.
After all, I was matched with Yvonne.
Thinking of not having to do everything by yourself, even Craft would feel relaxed and excited. He immediately decided to divide his paperwork into half of today's paperwork, leaving free time.
Apart from the failure of the experiment, he was still very satisfied with the new laboratory.
There is sufficient space and complete instruments, probably only comparable to the School of Medicine of Dunling University when Professor Morrison was still alive.
No, even Dunling University will not have such a large number of brand new glass instruments.
Rows of white glass strange-shaped pots and pots are placed in boxes lined with pure cotton pads. Perhaps they are also wondering why the owners of the experiment will observe the broth every day instead of focusing on complex physical reactions.
His failure obviously stems from the steepness of the difficulty curve.
The correct choice should be to pour the Petri dish with red, orange, blue and purple as soon as possible, wash your hands and lock the door and go to the next door.
The charity clinic under the monastery is about to open, so you have to prepare some stuff for the box as early as possible, so as not to be able to take out anything except praying and grass-roots boiling water.
However, what he wants to do is essentially not much different from boiling water from grass roots.
Cut two pieces of dried willow bark on the table and throw them into a round-bottom bottle. After pouring in high-concentration alcohol, the entire bottle is soaked in warm water and heated.
As a natural medicine, willow bark should theoretically be rich in salicyside, which can be extracted by alcohol.
The content is uncertain, no one has taught or read it. Craft is only familiar with industrial products and what it looks like after bottling with starch tablets.
Wait until the soaking is almost the same - of course, he didn't know when it was about the same, but just stared at the bottle with the color of the liquid gradually darkened, from light yellow to amber, and then took it out to cool.
Theoretically, salicylin should have been transferred to alcohol with the pigment.
The next step is to filter and remove the bark, then continue to heat and evaporate some of the alcohol, and concentrate until a higher concentration of solution is formed - don't boil it.
So the color of the liquid continued to darken and turned to brown. The suspicious filtering incomplete residue like tea residue churned up and down, like a nervous mood due to rough operation.
Out of concern, Craft filtered it with a tinsel cloth and added dilute sulfuric acid to it. It was a little more, but it didn't matter. In theory, it would require an acidic environment.
After the acidity is appropriate, the solution will be the hydrolysate of salicylin - salicyol.
That's right, according to the corner of the extracurricular interest expansion of a medical chemistry organic chapter, now as long as you drop concentrated sulfuric acid in it, the solubility of the oxidation product in an acidic environment is very low.
It's that simple, two willow bark, alcohol, sulfuric acid, and glass instruments worth a suite in Dunling Old Town. The next snow-like precipitation witnessed is the precursor of the legendary non-steroidal anti-inflammatory painkiller aspirin..., salicylic acid.
Compared with the acetylated brother, it has low solubility, poor absorption, outrageous taste, strong side effects of the digestive tract, and its anti-thrombotic effect is about zero. It is so irritating that it can be used to exfoliate the skin, but it is strong enough to be completed under existing theoretical conditions.
This is already the limit he can do, and his operational level is still far from that of Father Adrian, a master of distillation in port, who controls fire with bare hands.
"No, why didn't it settle down?!"
Chapter completed!
