What is the mechanism that prevents living tisse not to rot?
Our immune system takes care of that. Our bodies are continuously under attack from foreign invaders such as environmental toxins, pollutants, and germs. The immune system is our bodies natural defense mechanism against these attackers. The immune system is made up of white blood cells, organs and structures whose mission it is to identify and destroy disease causing organisms such as bacteria, viruses, fungi, and parasites. It’s the immune systems that'll protect the body against these foreign invaders, who would otherwise cause damage and/or rot. As for bacteria, fungi and parasites, they need enough oxigine to survive and to be able to help the rotting or decomposition process. Viruses usually die once the host cell they're living in died too, so when someone dies they die too. Organisms like maggots get attracted by the smell of dead flesh. That smell is the result of bacteria and fungi and parasites consuming dead flesh. Once flies, bugs, worms and other bigger organisms get attracted by the dead flesh decomposition will go fast.
To prevent decay having no oxigine around the dead body will help the most. Things like salt usually kill bacteria or slow them down and the salty smell stop the attraction of say maggots and the like. Largest part of decomposition happens not because of bacteria, but because of organisms.

Does anyone know the biochemical protection, that is imidiatly lost in case of death?
As long as most cells are alive, biochemical protection will be active, once organs and glans are dead and can't produce more anti bodies or react in general to the invaders, it will go very fast. They'll become literally outnumbered very fast, this happens in a matter of hours depending on the size of the dead body,
Cheers

So it is all the dominace of the immune system... Plants must have them too ? Ok, regarding the chinese mummies, that where not salt-dried as in Egypt, they must have killed all bacterias that could decay the body. Maybe they used Pastorisation ? Heating up the body above 78Celsius for a while, to kill every bacteria.... And then sealed the body hermetically in the coffin.

Yes, plants have it too, but they tend to be more vulnerable I think, because I'm not sure if plants have a system that can actively adapt to changing bacterias and things like that. Things need to go quite wrong before we humans actually get hurt by bacterias.

Generally speaking mummification will be the result of preservation by either intentional or accidental exposure to chemicals, extreme cold, very low humidity, or airlessness (oxigine-less is a bit more accurate). I know of some Chines e mummies who were found in ice, but I don't think you're talking about them, are you?

I was referring to this mummy: over 2000 yaers old, and still liquid blood in the veins. Even the arms can still be bend. Pretty impressive how the chinese conserved the bodies. http://www.zdf-enterprises.de/en/diva_mu...rom=64&l=en

Ah, yes, those are impressive indeed, I've read about them before. As for their exact mummification I don't know, but I would place my bet on some sort of poison/toxic this in conjunction with an airtight and oxigine low tomb, could very well have such a great mummification as result. They say environmental circumstances were far from optimal for mummification, so I expect a method which involved chemicals.
When toxic levels are very high in a body, bacterias and the like will naturally get no chance and will be slowed down tremendously. When a body is filled with toxics, it will decay at a much much slower rate,

Although theoretically it's a possibility, I think there's a problem with heating up a body. How would you do it? Boiling in (toxic) water isn't really an option, you'd definately damage the tissue, especially if the body dries out afterwards. Try boiling a chicken and let it dry out, it'll be a heap of flesh, by far not as flexible and intact as these mummies. Perhaps the boiling doesn't last very long, but to kill of all the bacteria in 1 human body you need quite some time I think. As for the temperature you'd definately need to reach a boiling point, otherwise most of the germs/bacterias won't die. Not all germs/bacterias life untill the boiling point of water is reached off course, but a small majority and the more hazardous bacterias usually do not die untill boiling point is reached. Hence, if you never heat it up untill the boiling point it wouldn't have maximum effect. Quote:
yes, but how can they apply toxins into the inner Body,
Good question, I don't know, perhaps applying a thick layer on the outside skin is enough to even cover the inside?
I do know that some Chinese emperors/high placed persons used to believe that they would become immortal by swallowing very hazardous toxic cocktails potions or 'tablets' near the end of their reign. A slow and very painful suicide, but I'm not sure if this was common for mummies at all. I do know that such entoxicated bodies usually are very good conserved.
All in all, I'd like to know how dry these mummies are and in what temperature they originally were found, because somehow the used mummification process seems to be somewhat of a mystery indeed, very interesting.

If they were wet, then probably they have been conserved this well because of the high acidity of the water they lay in. (In the netherlands we have several 'bog bodies' who are well conserved as well because of the airtight situation of the bodies being burried beneath the bog and high acid water, effectively sealing it.) It makes sense that it begins to rot fast after those coffins were opened, because that would mean no airtight situation anymore and oxigine would get in, this overall change of circumstances would make it possible to continue the process of decay.
