Suddenly I found out that these things should be related to what I just ate.
"Fuck, our body, why is this thing growing on this thing, isn't it too scary!" The little beggar said with a frightened face, he never thought that there would be corpse spots on his body, which made him unacceptable, he was a living person, how could he grow corpse spots.
"What do we do now? These things grow on our bodies, and we should be fine, but if there is, we will be in trouble! Dong Tinghua said with a frightened face, he never imagined that such strange corpse spots would grow on his body.
"Calm down, if my guess is correct, these things should have nothing to do with what we just ate, the reason why corpse spots will grow on our bodies should have something to do with the time we have been in here for too long, you don't forget that this is the Yin Qi of the underworld, we are under the erosion of Yin Qi, it is very likely to grow these things, it is also a very normal thing, if my guess is correct, when we leave here, these corpse spots should disappear, but if we stay here for too long, We may never be able to get out, so we need to find the soul of Zhan Tian as soon as possible and leave this place! Zhou Tianyi said nervously.
If you don't leave here again, everyone's body is covered with corpse spots, it will be a dead end, so now we must find it as soon as possible, Zhan Tian's soul leaves this place, the underworld is a place that erodes people's lives, and when the living come here, the yang energy is eroded, and it is very likely that they will die.
"Brother God, what are these corpse spots? Why will it grow in us! The little beggar looked puzzled and asked, I don't know what the corpse spot is?
Zhou Tianyi talked eloquently about the corpse spots.
After death, purplish-red patches that appear on the skin of the lower part of the corpse are called corpse spots.
It appears on average 2-4 hours after death. The formation of corpse spots is due to the cessation of blood circulation after death, and the lack of power of blood in the cardiovascular system and the accumulation of corpse along the vascular network.
As a result of the emptiness of the high blood vessels of the corpse and the congestion of the lower blood vessels of the corpse, the capillaries and venules of the lower part of the corpse are filled with blood, and the dark red to dark purple-red marks presented through the skin are cloud-like and lumpy at first, and finally gradually form flakes, that is, corpse spots.
After death, in addition to blood circulation, tissue fluid also accumulates in the lower part of the body, settles in the tissues around the blood vessels, enters the blood vessels through the blood vessel walls, mixes with the blood to promote hemolysis after death, and is then diluted by the tissue fluid.
The plasma stained red by hemoglobin seeps out of the blood vessels, which is the period of necrocer spot diffusion. It generally takes 12 hours for the corpse spots to develop to the diffusion stage, and it also takes 8~10 hours for the rapid progression, and the diffusion period is the continuation of the falling period.
During this period, the corpse spots fade slightly when pressed with the fingers, and after changing the position of the corpse, the original corpse spots are not easy to disappear, and new corpse spots are not easy to form. When the skin is cut open at the site of the diffuse corpse, blood droplets gradually flow from the broken blood vessels, and a small amount of reddish liquid overflows from the tissue.
From the beginning of the diffusion phase, the fluid stained by hemoglobin penetrates into the tissues, and becomes more obvious after the next day, not only penetrating into the interstitial space, but also infiltrating into the tissue cells, coloring the tissue, which is the infiltration period in the development of cadaveric spots.
The infiltration phase is a continuation of the diffusion phase and lasts for a longer period of time, after which it turns into corpse decay due to the action of bacteria. During the infiltration period, compression does not cause the corpse spots to fade, let alone form new corpse spots. When the lesion is cut open with a knife, the tissue is purple or light purple, and there is no blood outflow from the blood vessels.
The above is a general picture of the appearance and development of corpse spots. In addition, the speed and degree of appearance of corpse spots are also affected by various factors, the main ones are external pressure, blood quality, blood volume and skin color.
The depth of skin pigment also has an effect on the color of the corpse spots, the color of the corpse spots should be more vivid for the light-skinned corpse, and the color of the corpse spots should be darker for the dark-skinned corpse.
The color of the corpse spots depends on the color of the blood and skin. The corpse spots of Chinese people are usually purple-red, and the corpses of carbon monoxide poisoning are cherry red because the blood contains a large amount of bright red carbon monoxide hemoglobin, so the corpse spots that penetrate through the skin are cherry red.
The corpses that have been frozen to death and poisoned by cyanide are bright red because of the insufficient utilization of oxygen in their bodies and the high amount of oxyhemoglobin in their blood.
In the case of a corpse in water or in freezing conditions, oxygen penetrates into the subcutaneous blood vessels to form oxyhemoglobin, so the corpse spots are red or reddish. The burnt body was burned due to carbon monoxide inhalation, and the uncharred parts of the body were cherry red.
In the case of potassium chlorate and nitrite poisoning, the corpse spots are grayish-brown due to the formation of methemoglobin. White and black people have different skin tones and have different degrees of appearance of corpse spots. Black skin can mask the color of the corpse spots. As the postmortem changes develop, the dark purplish red of the corpse spots gradually turns to light green and green, blending with the color of the decaying corpse.
In the practice of forensic examination, it is also common to encounter disputes caused by mistaking corpse spots for subcutaneous hemorrhage and requiring identification.
Blood spots are plaques that are dark red or purple when blood is ruptured and bleeding under the skin or if you have diseases such as hemophilia, hemorrhagic purpura, scurvy, sepsis, etc., and the blood collects and coagulates in the subcutaneous tissue.
During forensic examination, it is necessary to strictly distinguish between corpse spots and blood spots, which are two essentially different phenomena. Generally speaking, corpse spots and blood spots can be distinguished from at least the following points. From the perspective of genesis, corpse spots are formed by blood accumulation, and blood spots are formed by suppression.
In terms of location, corpse spots are distributed in the lower and most compressed parts of the body, while blood spots can form anywhere on the body.
The edge of the corpse spot is not clear, while the edge of the blood spot is very clear.
Corpse spots can fade when they are pressed during the accumulation and spreading phases, while blood spots do not fade when they are pressed at any time.
The surface of the corpse spot is characterized by damage such as epidermal peeling and swelling, while blood spots are sometimes accompanied by violent injuries such as epidermal peeling and swelling.
The skin of the cadaver spot was cut open and observed, and the tissue was uniformly purple-red, while there was coagulated or liquid blood in the skin or under the skin of the blood spot, and its boundary was clear; Microscopically, there is no tissue and cell destruction in the corpse spots, while blood spots have obvious tissue and cell destruction.
Regarding the difference between cadaveric spots and blood spots or subcutaneous hemorrhage, China's classical forensic science has accumulated rich experience. This point has long been discussed in the "Collection of Evidence for the Record of Clearing Grievances", and there is a precise identification method.
In the "Autopsy" section of the "Collection of Evidence for Clearing Grievances", it is recorded: "To examine the injury, it is necessary to use the fingers to press the blue and red parts, which are hard wounds, and the fingers are still blue and red,...... It's a real injury. If the hair changes, it will be pointed to a point, and the starting finger will be white. β¦β¦ Hair change is the blood in the human abdomen, which is dispersed outside after death and cannot coalesce, so it is superficial. The injury was beaten before his death, and his qi and blood gathered into an injury. β
"Every dead man shall be on the back of his neck, on his back, behind his ribs, on his arms, and on his legsγ...... The stomach of the two feet is slightly red, which is caused by the blood falling on my back and mooring, not because I am dead. β
It is recorded in the section of "self-hanging": "After hanging, the blood veins are not good, the body is purple and black, like clouds condensing, and there are similar hair changes, which is called a blood barrier." With bruising and redness, then the blood barrier or less. The "hair change", "blood fall", and "blood barrier" here all refer to corpse spots.
It is generally dark purplish-red. Because within a certain period of time after death, because some tissue cells continue to consume oxygen in the blood due to the supernatural reaction state, oxyhemoglobin becomes reduced hemoglobin, and the blood is venous blood, dark red. The accumulation of blood has a quantitative process, so the color of the corpse spots is gradually revealed and deepened.
"Of course, some things will not have corpse spots, these corpses are very different!" Zhou Tianyi continued to preach.
Miao Weiqiang, Dong Tinghua, two-tailed scorpion, and little beggar stood next to him and listened quietly.
In the practice of forensic autopsy, there are often cases where the corpse spots are not visible in the lower parts of the corpse. This is mainly due to the pressure.
If the hard surface of the liner is uneven, the skin of the compression of the body can leave a pale area consistent with the hard surface of the padding, and there are still corpse spots in the places where there is no compression.
In this way, the dark purple-red corpse spots and the pale marks are more distinct.
In addition, the area where the trouser belt is ligated, the place where the garment is folded, or the skin fold is also free from the formation of corpse spots due to compression, and can leave marks consistent with the compression. Drowned corpses often appear slower and weaker because the capillaries are stimulated by cold water to shrink and the corpse floats and flips in the water.
"I didn't expect these things to grow on the human body, and there is so much scientific knowledge!" The little beggar said with a serious face, admiring Zhou Tianyi's erudition and talent, and among the five people, Zhou Tianyi knew the most.
"It seems that these things have a great impact on us, if we don't find the Zhantian Soul as soon as possible and leave here, we will most likely die here!" The twin-tailed scorpion said with a serious face.
"So what should we do now!" Miao Weiqiang asked a little puzzled.
"Brother Qiang, are you stupid, what else can you do now? The only way we have now is to find Zhan Tian's soul and leave here as soon as possible, this is the only way for us now! The little beggar looked at Miao Weiqiang with stupid eyes and said.
"It's such a simple question, even Xiao Hanako knows it, but Brother Qiang doesn't know, stupid!" Dong Tinghua looked at Miao Weiqiang with a look of contempt and said. (To be continued.) )
