Others were puzzled, but Qiu Feng reacted instantly, "Wait a minute, I'll get it."
Qiu Feng's father, Qiu Zhen, is the chief physician of the Imperial Medical Department, and this is half of her home. She ran into the room and soon took out a bundle of thoughts.
The thread used in the lesson class is made of many materials, including various metals, but also special spider silk and insect silk. More advanced ones need to be redeemed with credits.
The bundle Qiu Feng took out was a special kind of spider silk that was not sticky, but was extremely tough and soft. Li Ang later communicated with her about using thought threads to explore the human body, and concluded that spider threads had the best effect.
.
"Give."
Qiu Feng handed over the thought thread, and Li Ang took it. After cleaning it with saline, he injected the thought power into it.
Sha——
The spider thread trembled, and with everyone watching, it slowly penetrated Yi San's swollen abdomen.
Li Ang closed his eyes and released his mind power with great caution.
After he reached the high level of the hiding state, the effect of telekinesis scanning was much better than before. Although he could not see clearly the places slightly far away from the spider silk, it was more than enough to examine Yi San's abdomen.
There are too many parasites...
Under the belly with bulging veins, countless tiny insect bodies are squirming and rolling.
Every time the spider silk advances a few inches, you can see densely packed insects and insect eggs.
Sha——
Li Ang slowly retracted the spider silk and turned to look at Qiu Yan, "Doctor Qiu, there should be a microscope in the Imperial Medical Office, right?"
"Yes. I just bought one last month. Follow me."
Qiu Zhen nodded and led the way to a room.
Li Ang stepped into the room, and under the gaze of everyone, he skillfully used two glass sheets as slides, put something at one end of the spider silk into the slides, adjusted the parameters of the microscope eyepiece and objective lens, and observed the slides
.
Today's microscopes in Yu State are already quite excellent and can clearly see very small objects that are almost invisible to the naked eye.
But this time, two bugs appeared in the lens.
One is long and the other is short,
The short one is milky white, and the insect body extends to both sides and curls slightly toward the ventral surface, tightly hugging another insect.
The elder one is thin at the front and thick at the back, shaped like a nematode, dark brown, and nearly 25 mm in length.
The two insects hugged each other, entangled and difficult to separate.
The mouthparts can be vaguely seen at the top.
There are two forked tails below.
Under the microscope, the two worms are still squirming weakly. In their thin bodies, dark brown lines of flowing body fluids can be seen - that is digested human hemoglobin.
Footsteps sounded from behind, Qiu Feng came closer, glanced at the depressed and gloomy Li Ang worriedly, and said softly: "Risheng... are you okay?"
"I'm fine, just a little..."
Li Ang let go of the door frame, and for a moment he didn't know what to say. He could only hold back the word "despair".
I'm afraid no one in the world knows schistosomiasis better than him,
No one knows better than him how terrifying schistosomiasis is.
This parasite belongs to the phylum Platyhelminthes, the class Flukes, the subclass Polygonidae, the order Polygonidae, the family Schizosomatidae, and the genus Schistosoma.
During the life cycle, there are 7 developmental stages: adults, eggs, miracidia, mother larvae, sporcariae, cercariae and juvenile larvae.
Start with the egg stage first, and under suitable air and water temperatures,
The eggs will hatch into miracidia, which will quickly find the intermediate host snail in the water, invade its body, reproduce asexually, and gradually develop into mother larvae, daughter larvae, and cercariae within a few months.
Cercariae swim actively in the water. Once they find a new host, they will use the opening in the front part of the worm's body to secrete tissue enzymes and burrow into the host's skin.
Subsequently, the cercariae will take off their tails and enter the bloodstream. They will be transported throughout the body along with the blood or lymph. After the male and female mate, they will migrate to the portal vein-mesenteric vein to reside and mature.
After 24 days of invading the host, they begin to mate and lay eggs.
A female worm lays about 1,000 eggs every day, half of which enter the bladder and are excreted in the urine. The remaining eggs are deposited in the liver, rectum, colon, appendix, lungs, brain and other organs.
Mature eggs contain mature miracidia, and their secretions are antigenic, causing egg granuloma and subsequent fibrosis, leading to liver cirrhosis and portal hypertension.
Clinical manifestations include ascites, splenomegaly, esophageal varices, etc.
Five weeks after infection, hatchable eggs will appear in the host's feces, and the eggs will float away with the water and begin the next round of reproduction, parasitism, and transmission.
Crack——
In the night sky, New Year's Eve fireworks bloom brightly,
Li Ang stood at the door of the lobby, with his back to the bright sky, staring at the hospital beds.
...can it be controlled?
The cercariae of Schistosoma are spread along with water flow, and any behavior such as fishing, swimming, laundry, or foot washing in the water may lead to infection.
Even if you just step on the infected water, you may be parasitized.
The farmland and river areas of Yu State are too large, and shipping is extremely developed.
Oncomelania, the intermediate host of schistosomiasis, can easily attach to shipping ships and spread to distant places as the ships spread, expanding the scope of their infestation.
Just like dropping a drop of ink on paper, it will spread around along with the grain of the paper.
So, is it cured well?
The best drug for treating schistosomiasis is the pyrazinoisoquinoline derivative, praziquantel.
At present, its production process is a hundred or a thousand times more complicated and difficult than that of allicin and penicillin.
Almost impossible to produce.
Considering that these patients in the lobby are all in the late stages of schistosomiasis parasitism... the actual transmission situation is worse than expected.
How many people are infected by schistosomiasis?
Two hundred thousand?
Three hundred thousand?
Or...millions...
In the night sky, the fireworks gradually stopped.
Li Ang's face was once again hidden in darkness.
