The first step in studying a specific plague is either to try to isolate the pathogen and cultivate it separately, or to conduct a pathological analysis.
The separation of pathogens is difficult and difficult, and easy and easy.
Like many empirical ways of life, this is also a process of looking at the face.
Inject substances that may contain pathogens into a suitable environment, and then, the tiny creatures that may be pathogens will increase on their own.
Of course, the cultivation of pathogens and parasites is the simplest. Their medium only needs to include inanimate agents containing nutrients. This is not the case with more subtle creatures.
Viruses, chlamydia and other pathogens lack the ability to synthetize enzymes and cannot complete many reactions necessary for life. They need to live among living objects.
Animal embryos are a very good choice-because compared to adults, embryos are easier to culture, and it is difficult to produce messy antibodies.
The "less antibody" element is the reason why fetal calf serum is superior to newborn calf serum, and neonatal calf serum is superior to calf serum.
Of course, a calf weighs many times heavier than a fetal calf and can extract more serum than a fetal calf. In addition, the production environment of fetal bovine serum is more demanding, so in terms of price, fetal bovine serum is more expensive.
This is also the reason why scientists on earth study why vaccines consume eggs-eggs are also embryos, chicken embryos.
Even to say that in the 21st century, the earth's vaccine industry is also a big consumer of eggs.
The principle of the vaccine is to inject the inactivated or attenuated pathogen into the human body, but also to cultivate the pathogen.
The major influenza vaccine manufacturers all over the world are still mainly based on chicken embryos.
The reason is simple and cheap.
The breeding cost of chickens can be much lower than that of cattle. The price difference between chicken and beef really reflects this.
Even more commendable is that chickens, as poultry, have an advantage that mammals can hardly match-every egg can be equivalent to a closed sterile bioreactor. If you choose eggs, even the requirements of the production environment can be reduced.
Of course, egg as a medium for vaccine production is not a panacea. First of all, if the outbreak of the plague is avian flu, etc., which is more lethal to poultry, do n’t cultivate it. The embryo in the egg will be killed by the pathogen before the cultivation is completed.
In addition, if there is a sudden large-scale outbreak of plague, the output of the vaccine is destined to keep up-after all, this is still positively related to the poultry industry.
In addition, those with egg allergies have to be a bit unlucky.
Therefore, most of the earth's pharmaceutical companies are researching related technologies of bacterial culture. However, at least in the early 21st century, there is no mature technology.
Of course, China does not need this technology. For most diseases, you can rely on spells to improve vitality, hang your life, and then drag it to the body to produce antibodies or immune cells with non-specific anti-infection functions to kill all pathogens.
Of course, there is another set of treatments for immune diseases resulting from overreaction of the immune system, as well as secondary immune deficiency diseases.
By the way, in the secondary immunodeficiency disease, the well-known acquired immunodeficiency syndrome ... has not yet found its trace on China.
However, at present, this method is still difficult to apply.
This batch of topaz samples was collected at the beginning of Wang Qi. At that point of time, Aluer, a fairy, was still asleep, and the controller on the surface of Huang Jing's earth was the unknown Lauder Zerg. The Lauder Zerg, known as the "Huangjing Demon", did not have much understanding of the essence of Huangjing's law, but could only simply control and infect.
This batch of topaz samples is aimed at the creatures in the same biosphere of the Yuan tribe.
That is because Lauder Star used to belong to Yuan Family, and the creatures on Lauder Star are directly related to Yuan Family Mother Star. Otherwise, if you change the planet, "The Yellow Crystal Devil" will not appear at all.
This piece of citrine can't infect the source dragon star creatures-whether it is human races or breastfeeding creatures, or birds.
Unless Tianlingling is willing to risk the entire generation of the Shenzhou breeding industry, collect all the eggs in Shenzhou, and then bet on this batch of citrine, even if a pathogen has mutated the ability to infect the source dragon star.
So the question is coming-where can you find the creatures that can cultivate the pathogen of citrine?
When the unit of Zhengtian Division arrived, apart from the Lauder Zerg, only Algae black anaerobic bacteria remained on Lauder Star.
If you want to use Lauder eggs as a culture medium, then the Lauder family may have to rise up to resist, and the Neptune class is also likely to centrifuge from Germany. The reaction of the demon and dragon clan must be considered.
In addition, there will also be many people who cannot see in Xianmeng.
The only remaining options are the existing seaweed, anaerobic bacteria, or the living tissue of Lauder that was taken from the Lauder sample brought back to China and then expressed by the chemical method.
However, no matter whether it is the Lauder Zerg or the Lauder seaweed, their ecological, genetic, and spiritual properties are not understood by the human race.
Ghosts know which components are pathogens, which components are their original, or by-products of pathogens' physiological activities.
No one stipulates that citrine must be the main body of the citrine pathogen—it may also be a metabolite of the citrine pathogen?
Then there is only pathological analysis.
"I remember right ... This link should be combined with medical history for histopathological examination ..." A Tianlingling Yuanshen monk looked at the sample in front of him and showed a discouraged expression: "We also don't understand the physiology of these insects- I heard that they still have incomprehensible behaviors such as traumatic, insemination, and sperm. "
"On this point, the planet that the Lauder Zerg has traveled to has already been investigated by the same class."
Another disciple stretched his neck over and whispered, "These guys can't completely understand their own flesh, nor can they be without medical treatment."
"Weishengju is also studying those anaerobic bacteria and seaweed." Another said: "We mainly conduct histological research."
According to the reaction of the sign angel who came into contact with Huang Jing, the infection of Huang Jing mostly started from the nervous system. Therefore, in addition to Jiyin Valley, the most is Yangshen Pavilion. More than half of the Yangshen Pavilion monks are also within reach of histological research.
Chen Feng skillfully took a few samples of seaweed for initial fixation.
The so-called "fixed" is the standard starting point for pathological research. After the pathological sample is isolated or died, due to changes in the microenvironment, autolysis and spoilage will occur, and its structure is easily destroyed. The "fixation" is to keep the pathological specimen as original as possible.
First, it shows that using thermodynamic spells to lower the temperature. This is mainly to coagulate the source substance and reduce or stop the action of certain enzymes, so that the autolysis of the cells stops, and also ensure that the antigen is not inactivated.
Most of the people doing the study of the way of life understand thermodynamic spells in one or two hands. It is said that some well-tested monks have even repaired one or two layers of Heaven Entropy. Some people inside Tianling Mountain even feel that this kind of living pulls one or two outside doors of Burning Tianfu House may be better.
Then, it uses the magic of the burning gold valley to separate out the water.
This kind of spell is like the way of looting atoms in a certain proportion in Chaotianwaidao, but with a lower configuration. A spell can only target one physical property and is difficult to apply to combat.
Next, it is time to test the practice. In this step, the researcher needs to use softness and darkness to take a fixed object such as paraffin into the sample without destroying the sample structure.
Of course, if you are not in a hurry, you can let paraffin slowly infiltrate. However, there is always the risk of spoiling the sample.
A monk like Xiang Chenfeng can only control his strength and slowly pat on a sample.
Of course, fixed observations are only part of it.
Anyone who has enough cultivation and masters any subliminal magical power of Life Flame can choose to use Life Flame to suspend the life of the sample, and then observe slowly.
But this also has the problem of pathogens multiplying and changing the sample structure. It is said that there was a rather exaggerated scene observed by Tianlingling disciples-under the effect of life inflammation, the excessive reproduction of pathogens ultimately did not let the sample die but physically destroyed the sample structure.
That scene was very harmful to mental health.
Of course, both pathological observations need to be made.
However, this kind of direct observation is unlikely to yield results.
Huang Jing is actually Aluer's body. The power of Huangjing is part of Alu's fairy power-the fairy power attached to these samples collected by Wang Qi is not enough to fully carry Aluer's consciousness. Realize the transfer.
But at the level of "molecules", this group of spiritual forces is amazing-it isolates many temptations.
This is a natural package. Considering that the Yuan tribe is no stranger to the plague spell, perhaps they will also specifically strengthen this interference with vision and spiritual knowledge. But if there is no such fairy power, then the unique structure of the citrine pathogen will not exist, and if it is broken up, the pathogen will instantly die and decompose.
It is conceivable that on the first day, there will be no gains.
Five days later, Helix Shuangzun pretended to announce one thing easily at the rally: "At least we can be sure that the pathogen is neither a pathogen nor a parasite."
This joke won an awkward and polite smile.
Everyone knows.
After all, the report given by Zheng Tiansi clearly stated that the yellow crystal plague can distort the cell structure of the infected person. It's not like it can be caused by germs or parasites.
But ... there is still a possibility of losing it-in case a certain metabolite of a bacterium or parasite can achieve this effect?
Now, the possibility of this loss is ruled out.
This is also very good! Isn't this a result?
"So, we took a small step successfully." After Chen Feng dragged his tired body back to Ai Qinglan's ward, he put on his hometown accent and repeated to Ai Qinglan: "You Said. "
"At this time, you should say-too ​​boring! Is there no more interesting gameplay?"
"Well, of course, there are comparisons ... playing your own game."
