Chapter 459 Visiting the Laboratory
Little Louis had heard the imperial doctor teach some medical skills before, and personally tested Teo and the others' pulses. He was relieved to see that everything was normal with them.
As soon as he walked out of the tent, he saw a knight pulling a sheep. He thought that the mutton was not enough for one sheep. Could it be related to the treatment of diseases?
Curiosity led him to a group of strange tents.
Two tents have a cordon set up 10 meters away. Every three meters there is a bilingual warning sign saying "No entry for idlers". One tent is connected to the water pipe and the drainage ditch. There is a A sealed corridor connected the two tents together. The other tent was sealed tightly. There was a cabinet by the door that penetrated the tent cloth. There were several machines that looked like blowers between the two tents.
Friedrich was checking the sheep that had been delivered. The sheep looked healthy. He nodded and said a few words to the people next to him.
Little Louis went over and asked: "Professor Friedrich, can I go in and visit?"
Friedrich thought for a while, nodded and said: "No problem, but in the laboratory There are many requests, please obey and obey the command."
Little Louis agreed immediately.
He has heard that magicians' laboratories are very dangerous, and you will die if you mess with them.
Then Friedrich took him to the first tent. First, he had to take off all his clothes, wash his whole body with sulfur soap and a white soap, and then put on the clothes prepared inside.
Little Louis did as he was told out of curiosity. He washed it carefully in the bathroom, went to the dressing room and put on underwear and outerwear all made of white cotton, a mask, a hat, and white cloth shoes. .
The curtain when you walk out of the dressing room is made of airtight tape. There are magnets that suck on both sides and close it automatically. Wind blows out from the gap.
Frederich taught little Louis how to push the door curtain away from him, and then washed his hands again with alcohol on the table next to him.
At this time, a young female researcher walked out of the ladies area next to her. When she was disinfecting her hands, Friedrich said to her: "You will do the yellow plate later, and I will do the blood plate. Except for the patient, If you still have a reference, make two sets, don’t forget.”
Little Louis couldn't understand it, but he thought it was very powerful.
Walking through the corridor, the things in another tent made him feel even more powerful.
There are many cabinets and tables here with big labels on them, which say petri dishes, beakers, golden bean liquid, beef extract, agar, heating table, purified water, sterilization table, operating table, refrigerator, constant temperature Incubator, etc. Can Little Louie understand and not understand the words?
Manuel was already here. When he saw Friedrich come in, he said to the outside: "You can take blood."
Little Louis thought he was taking the blood of the sheep just now. Well, turn around and ask Friedrich: "Is there anything I can do?"
Friedrich thought for a while and said: "There is a physical job. I wonder if your highness would be willing to give it a try."
Little Louis immediately agreed, but the physical job is fine, and the technical job can't be done by himself. .
Not long after, someone outside knocked on the cabinet that connected the inside and outside. Manuel used magic to sterilize the cabinet, and then took out a glass Erlenmeyer flask filled with a lot of sheep blood.
He took the Erlenmeyer flask to the sterilization table and sterilized it again. Friedrich took it to the operating table and poured a lot of small glass beads about 3mm in diameter into it and put a cork on it, and let little Louis Shake continuously for 15 minutes.
Frederick said to little Louis: "This is to remove some things from the sheep blood so that the blood will not coagulate. Shake it and pour the top part into another beaker, and then put it in Store in refrigerator ”
"If His Highness feels bored, you can shake it while watching us making things."
Little Louis asked a little nervously: "Aren't you going to put sheep blood into your father's veins?"
He is a little worried, what if his father likes to eat grass in the future?
“How is that possible?” Friedrich smiled and shook his head, “Everyone can have blood transfusions and something will happen to them.”
“Blood transfusions have been studied between people for hundreds of years, and some people survive Some people died. The reasons are being studied. I hope there will be results within fifty years.”
"This blood is used as a culture medium to observe what kind of bacteria are in His Majesty the King's blood and whether they have been completely cured."
Little Louis breathed a sigh of relief, that's good.
At the heating table, the female researcher and Friedrich began to heat the purified water extracted by the water displacing technique in a beaker, and then poured in the weighed salt, golden bean liquid and beef extract. The latter two reagents have to be placed on the sterilization table for Manuai to disinfect after they are opened and sealed.
Little Louis asked curiously what the latter two things were. Friedrich said: "Golden bean liquid is a by-product of golden beans making bean cheese, and beef extract is the product of hydrolyzing beef. It is cultured The bacteria provide nutrients.”
Unexpectedly.
When fifteen minutes were up, Little Louis put the triangular beaker on the table, waved his hand, and under the guidance of Friedrich, poured the supernatant into the beaker, covered it, and put it in the refrigerator. At this time, a jar was delivered from outside. It was made of black iron. Little Louis had seen good things, and he could tell at a glance that it was a metal that could defend against magic.
He soon found out that it was to defend against Manuai's disinfection magic.
There was some alcohol in the jar, and four small glass bottles with lids on them, with ropes of different colors tied around their necks, containing blood.
Little Louis asked: "Which bottle of blood belongs to my father?"
Friedrich shook his head and said: "I don't know. We just use the blood sent for culture. Only Dr. Frank knows the details."
"However, according to my experience, the blood of weak people Darker.”
Little Louis saw the obvious difference in the color of the four bottles of blood and understood in his heart.
Put the four bottles of blood in the refrigerator first and won’t use them until later.
After a while, the female researcher over there cooked the culture medium, took out 12 petri dishes from the cabinet, and poured the culture medium into them.
Friedrich asked her to boil water in a large beaker, put a certain amount of the sheep's blood that little Louis shook just now into a small beaker, and then heat it over the water.
Little Louis asked curiously: "Why is it frozen for a while and heated for a while?"
Frederich replied: "It is frozen to prevent it from deteriorating. Blood is easy to "It's bad."
"The heat must be poured into the jelly. If it is too cold, the jelly will solidify and become uneven."
Little Louis didn't understand. Got it, but got it quickly.
Friedrich used a thermometer to measure the temperature of the culture medium he cooked. When it just dropped below 42 Webster degrees, he poured in the sheep blood with a lower temperature, stirred evenly immediately, and then poured it into the 12 newly taken out petri dishes. inside.
After a while, the culture medium cooled down and solidified.
The female researcher wrote the number and date and time on the piece of paper, pasted it on the bottom of the petri dish, placed it on the sterilization table for Manuel to sterilize, and then placed it on the operating table and arranged it according to the number.
Under the current conditions, they can only do blood culture using the dilution coating plate method. Four bottles of blood are diluted 10, 100 and 1000 times with pure water, and one of the two culture media is placed , flatten it with a triangular glass rod, and finally place it in an incubator for culture.
When leaving the laboratory, Friedrich said to little Louis: "The results will be available in 24 hours at the earliest. Generally speaking, the results within 48 to 72 hours are the most reliable."
< br>
Little Louis just nodded. The unprecedented experience just now deeply shocked him.
He looked back at the laboratory and asked, "Isn't such a laboratory very expensive?"
He didn't know anything else, just those glasswares. Cheap.
Friedrich said: "I don't know the specific price. It is all handled by the principal, but I know it is worth it."
"A building in the Principality of Mainz four years ago Jet diarrhea broke out in a small town. We didn't have such good conditions at the time. We drove there by horse and cart. It took three days to determine the cause and the source of the disease, and another two days to find the right medicine. In the end, the plague was brought to an end in less than a month. Control the symptoms. ”
"The principal only started to study this laboratory after that time, so that he can go wherever there is an epidemic."
Little Louis' eyes were red, and he almost wanted to pack up Friedrich and the others and kidnap them away. .
Spray diarrhea is a very serious infectious disease, with a mortality rate of more than 60% and spreads quickly. This alone is enough to see the value of the laboratory.
But little Louis is depressed again. Now that the war is approaching, the country does not have so much money to invest.
But he also thought that now he had a good set of cards in his hand, which he could play to Archduke Wesson as he liked. At least when a plague broke out, he could hire this laboratory to fly over to save lives?
But another question came to his mind. There were too many cards and he didn't know which one Archduke Wesson liked. How about playing them all and seeing which one he would pick?
Little Louis quickly made a decision. Since those cards were to be played before the next war, it would be better to use them here first.
