Chapter 81 Anatomy!
Although Mr. Sui's skull was very strong, it still didn't last long before it was opened in the face of modern craniotomies.
When his head was opened, waves of exclamations sounded again.
"The dura mater is actually still intact and shiny!"
"The meningeal blood vessels are also clearly visible, and the twelve pairs of cranial nerves are almost identifiable!"
"Oh my God, this is amazing! The brain is still there!"
Professor Wu Tinggui reached into his skull with both hands, took out a grayish semi-solid object that looked like a pig brain cooked in a hotpot restaurant, and placed it on the weighing machine that had been prepared by an assistant nearby.
“970 grams! Amazing!”
This piece of brain occupies four-fifths of the space in the cranial cavity.
In layman's terms, this is the human brain organization.
The average weight of brain tissue is around 1,375 grams.
Mr. Sui has been dead for 2,100 years, but there are still 970 grams of brain tissue left. The shrinkage is so small, the shape is complete, and there is basically no liquefaction. This is simply a medical miracle.
Generally, after a human dies, the brain tissue will begin to liquefy irreversibly, and then the meninges will rupture and all will turn into a pool of "brain" and flow away. Finally, after the external tissue of the skull rots, only the skull will remain.
However, Mr. Sui's meninges are very well preserved and still play a role in fixing brain tissue. This means that after two thousand and one hundred years of sleeping underground, the tissue structure of his brain is still very intact.
"This is even better preserved than Mrs. Xin Zhui's brain. Mrs. Xin Zhui's brain has shrunk by half and looks like crumbs!"
"This Mr. Sui's brain cells are basically well preserved, and even his cranial nerves are still there!"
Professor Lu Xingwen from the Institute of Biology looked with bright eyes at the "Mr. Sui's brain" which was immediately put into the antiseptic protection solution after being weighed, as if he was looking at some rare treasure.
In fact, it is indeed a rare treasure.
In 2008, archaeologists discovered the best-preserved ancient human brain in the village of Heslington, near Yorkshire, England.
This brain was named "Heslington Brain".
According to subsequent research, it can be determined that this ancient British man probably died between 673 and 482 BC, and was only in his 30s at the time.
And the method of death was very cruel. He was hanged first, and then beheaded with a knife. His head was cut off and buried immediately until it was discovered by archaeologists.
As we all know, brain tissue is composed of protein, so it breaks down faster than other parts of the body, making it difficult to preserve.
Therefore, well-preserved ancient human brain tissue plays an important role in protein labeling research, medicine, structural and functional proteomics, biomedical applications and archaeology.
Like the "Heslington Brain", due to its unique protein folding method, if it can be thoroughly studied, modern scientists may have important clues for treating dementia patients.
In 2013, American archaeologists discovered a brain that was over 4,000 years old in Turkey.
Don't ask why American archaeologists are doing archaeological work in Turkey. Do they have anything that they can do archeology at home?
Anyway, it is also due to special reasons, natural disasters and special environments that the brain has not decayed and disappeared for thousands of years.
This brain is also helpful in studying the causes of modern brain diseases.
The most important thing is that these two brains are of great significance to the study and understanding of the brain structure of ancient humans.
Before Mr. Sui appeared, China had discovered many incorruptible corpses one after another.
But more than two thousand years ago, all brain tissue has decomposed.
The best preserved Mrs. Xin Zhui's brain has shrunk by half and her tissue structure has been destroyed.
Only Mr. Sui has a brain so complete that even the cranial nerves are still there!
This has important research value in human biology and modern medicine!
No wonder Professor Lu Xingwen regards it as a rare treasure!
For an old professor who studies human biology, what could be more attractive to him than brain tissue from two thousand years ago?
Seeing Professor Lu constantly observing the brain soaked in embalming fluid, Kong Jianwen persuaded with a headache:
"Professor Lu, please wait until the dissection is completed for the specific research before reporting to your superiors!"
"The most important thing now is the race against time for the anatomy. Every second that passes, Mr. Sui's body may decay faster!"
When Mrs. Xin Zhui was unearthed, the preservation situation deteriorated extremely due to the difficult conditions and lack of awareness of protection, making the originally lifelike body unsightly and severely damaged.
By the time the "underground palace" was built in the Hunan Museum for preservation, Mrs. Xin Zhui was completely different from when she was first unearthed.
It can be said to be a great regret in the history of Chinese archeology.
Although times have advanced, so has technology.
Everyone already has experience in handling wet corpses, and the conditions have improved, including a sterile laboratory and so on.
But an anaerobic anatomical environment certainly cannot be created.
Mr. Sui was exposed to an oxygen-rich environment. Even if there were no bacteria, the inactivated human cells would self-decompose after being exposed to oxygen.
Therefore, shortening the dissection time as much as possible and then properly embalming Mr. Sui is the best way to preserve this "Chinese treasure".
Under Kong Jianwen's reminder, the dissection speeded up again.
Professor Wu, the surgeon in charge, kept switching dissecting tools, opening Mr. Sui's abdomen with crisp and precise movements, and then uncovered each organ and put it into a specially preserved antiseptic container.
"The internal organs are also well preserved and basically complete."
"The liver has a clear appearance and the gallbladder is slightly enlarged."
"The cause of the swelling has been found. There are more than twenty gallstones in the gallbladder."
"Well, there were residual lesions of pleurisy, pericarditis and cholecystitis in the organs of the deceased. They are all chronic diseases of the elderly."
"However, there are many things that look like insect eggs in the liver tissue. The eggs that can survive in the liver are probably schistosomiasis or liver flukes."
"Hey, there are also some insect eggs in the intestines. We need to send them for testing to find out exactly what they are."
Chen Han, who had been listening to the experts' autopsy reports, whispered to his instructor: "Well... I remember that Mrs. Xin Zhui in Mawangdui also found hemorrhoidal eggs in her body."
"Now Mr. Sui also has schistosomiasis eggs in his body."
"Does this mean that the records in our country's historical documents and ancient medical classics about the prevalence of schistosomiasis in the two lakes areas two thousand years ago, as well as the records about the phenomenon of schistosomiasis, are accurate and accurate?"
Kong Jianwen nodded: "Of course it is accurate!"
"Schistosomiasis was very frequent in the southern region during the Western Han Dynasty, and no one from the poor to the high-ranking nobles could escape its troubles."
"As the wife of the Prime Minister of Changsha, Xin Zhui was also attacked, and Mr. Sui, the fifth official, is obviously not immune to this."
While Chen Han and Kong Jianwen were chatting, the team of medical experts on the dissecting table were also dissecting steadily and orderly.
Under the leadership of the two professors, the dissection was very smooth and fast.
