Chapter 841: Serum (Page 1/1)

The soldier couldn't have been happier when he had received the gift from the Supreme Treasure, and after trying to walk a few steps, although he was not as nimble as before, he was able to walk normally, and he smiled at the Supreme Treasure as he jumped, smiling like a child.

"Thank you, Chairman, I like this leg so much! I will continue to fight for the PLA to the end with this leg! ”

"Well done!"

Supreme Treasure seems to have seen the brightest smile in the world, it is because of such a hard-working young man to join, the People's Liberation Army can come to this day, can lead everyone to a happy life, these people are indispensable!

But a better future is always to be realized, and the Supreme Treasure consciously takes on this responsibility, he wants to change his life against the sky, not only to change his own destiny, but also to change the fate of the entire era. And the first step is to start by solving the problem of poisonous snakes.

After handing out an emergency manual, Supreme Treasure finally began to think of a way to solve snake venom as quickly as possible, and that was to develop a poisonous snake serum. Speaking of this serum, Supreme Treasure really understands something. When his parents were still alive, his father was accidentally bitten by a poisonous snake when he was a businessman in a foreign country, and the supply of antivenom in the market was cut off. My father, who was doing business in Wuhan, finally went to Guangdong and was injected with an antidote serum to save his life. originally thought that there would be a blessing if he didn't die in a catastrophe, but in the end, the whole family except for the Supreme Treasure did not escape the pursuit of death.

At that time, the Supreme Treasure was still a very studious college student, when he learned that his father was bitten by a poisonous snake, he was very nervous, and personally accompanied his father to Guangdong for medical treatment, and witnessed the shock that the serum brought him, so he was studious and had a strong interest in the serum, and also read some books to do a certain amount of research on the serum.

In fact, the principle of antivenom is that after a small amount of snake venom is injected into the animal for many times, the antibodies produced by the animal are purified, which contains high-valent antivenom antibodies. When bitten by a snake, snake venom enters the body, which is an antigen for humans. The injected antivenom contains the corresponding antibody, which can neutralize the corresponding snake venom, specifically bind to form a complex, inactivate the toxin, and be processed by the corresponding phagocytic cells of the body, so that the toxin loses its effect on the person. Therefore, after being bitten by a venomous snake, the shorter the time after the initial treatment of the wound, the antivenom should be injected into the body, the more beneficial it is for the body.

There are more than 650 species of poisonous snakes in this world, and about 200 species can kill people. There are one hundred and fifty-eight snakes in the Celestial Empire, 47 kinds of poisonous snakes, 10 kinds of fatal snakes, there are big king cobras, golden krait, silver krait, pit viper, five-step snake, bamboo leaf green, sea snake, viper, soldering iron head, etc., among which the big king cobra is the most poisonous.

Serum, which refers to the yellowish clear fluid isolated from the plasma after the blood has clotted or the plasma from which the fibrinogen has been removed. Its main role is to provide basic nutrients, provide hormones and various growth factors, provide binding proteins, provide contact promotion and stretching factors to protect cell attachment from mechanical damage, and play a certain protective role in cells in culture.

The varieties of serum produced include fetal bovine serum, dialysis fetal bovine serum, stem cell culture fetal bovine serum, special-purpose fetal bovine serum, glucose-treated fetal bovine serum, fetal bovine serum substitute, calf serum, newborn bovine serum, enhanced calf serum, iron-supplemented calf serum, adult bovine serum, donor horse serum, rabbit serum, chicken serum, pig serum, horse serum, other animal serum, synthetic serum substitutes.

Serum contains various plasma proteins, peptides, fats, carbohydrates, growth factors, hormones, inorganic substances, etc., which are physiologically balanced in promoting cell growth or inhibiting growth activity. Although there has been great progress in the study of the composition and function of serum, there are still some problems.

The main reason is that there may be hundreds of components of the first serum, and its exact composition, content and mechanism of action are still unclear, especially for some of the peptide growth factors, hormones and lipids, etc., which brings many difficulties to the research work. The second serum is mass-produced, which varies greatly from batch to batch, and the shelf life of the serum is up to one year, so it is extremely difficult to ensure the similarity of each batch of serum, so that the standardization and continuity of the experiment are limited; Thirdly, the presence of volatile substances in the serum cannot be ruled out, which is considered one of the causes of "deterioration in the bottle".

After thinking about it, the only test subjects in the army that can be used well as serums are these war horses. To this end, he specially selected a few refined war horses, using horses to breed antivenom, the general method is to inject the horse with a non-lethal dose of snake venom, after a period of time, the horse has immunity to snake venom, at this time the horse blood is drawn out, extract antivenom.

ResultsIn the first phase of the study, ten horses were used. At the beginning, because the snake venom was hand-taken by the Supreme Treasure, who was not afraid of snake venom, the dosage of snake venom was not well controlled, and a few horses died. In the end, he made the real snake venom according to the experimental records of the experts in this encyclopedia. At the beginning, there were two kinds of antivenom, anti-silver snake venom and anti-five-step snake venom, mainly because these two snakes are widely distributed in Yongzhou, and there are more people who die and are disabled because of them every year, which is also a great good deed for the benefit of the people of Yongzhou.

Supreme Treasure personally tested the snake venom he made, and let himself be bitten by a poisonous snake first. Although he has strong antibodies and is not afraid of these poisonous snakes at all, he still feels slightly dizzy and uncomfortable. But after injecting myself with snake venom, the time to recover is shorter than before, and it seems that this serum is really effective!

Although the serum has been developed, the Supreme Treasure knows that this snake venom serum is not available to everyone. It can still bring some adverse effects. The first is anaphylactic shock, which can occur suddenly during or within minutes to tens of minutes after the injection. The patient suddenly presents with depression or irritability, pale or flushing, chest tightness or wheezing, cold sweats, nausea or abdominal pain, rapid pulse, decreased blood pressure, and in severe cases, coma and collapse, and can die quickly if not rescued in time. Mild cases can be relieved by injection of epinephrine; Severe cases require infusion of oxygen, vasopressors to maintain blood pressure, and anti-allergy drugs and adrenocorticosteroids for rescue.

The second is serum sickness, the main symptoms are urticaria, fever, lymphadenopathy, local edema, occasional proteinuria, vomiting, arthralgia, erythema, itching and edema at the injection site. It usually occurs seven to 14 days after the injection and is called the delayed type. There are also cases of onset 2 to 4 days after injection, which is called accelerated type. Calcium or antihistamine drugs can be used to deal with serum sickness, and it can usually be cured in a few days to more than ten days.
