Suspended Animation In Mice Without Freezing

kdawson posted more than 6 years ago | from the you-will-sleep-now-and-when-you-wake dept.

Medicine 147

Predictions Market writes "Low doses of hydrogen sulfide, the toxic gas responsible for the unpleasant odor of rotten eggs, can safely and reversibly depress both metabolism and aspects of cardiovascular function in mice, producing a suspended-animation-like state that does not depend on a reduction in body temperature and include a substantial decrease in heart rate without a drop in blood pressure. The researchers measured factors such as heart rate, blood pressure, body temperature, respiration, and physical activity in normal mice exposed to low-dose (80 ppm) hydrogen sulfide for several hours. In all the mice, metabolic measurements such as consumption of oxygen and production of carbon dioxide dropped in as little as 10 minutes after they began inhaling hydrogen sulfide, remained low as long as the gas was administered, and returned to normal within 30 minutes of the resumption of a normal air supply. 'Producing a reversible hypometabolic state could allow organ function to be preserved when oxygen supply is limited, such as after a traumatic injury,' says the lead author of the study. 'We don't know yet if these results will be transferable to humans, so our next step will be to study the use of hydrogen sulfide in larger mammals.' The full report is available online."

Would you be willing to live in pain, and as a major burden to society and your family in exchange for an extra year, especially at such an advanced age?

Re:Yeah but... (1)

hughk (248126) | more than 6 years ago | (#22869992)

Yes, it was one of the nasties that the engineers would warn us about when visiting plants. We weren't certified plant workers so we had to get the safety briefing each time we went onto the plant (you know, after being searched for matches etc). Once you were on the plant, if the alarm went, you ran as fast as possible and even that could be too late.

Re:Yeah but... (3, Informative)

Teun (17872) | more than 6 years ago | (#22868992)

The safe level to work in for 8 hours per day (MAC value), 5 days per week has recently been dropped from 10 ppm to 2 ppm.
80 ppm of H2S is going to be lethal after 8 -24 hrs of exposure, much earlier you will be suffering bleeding and other very unpleasant effects.
At 500 ppm you're dead in 30 to 60 minutes and at 800 ppm you will not survive 2 minutes.
The kicker is at 1000 ppm, you're immediately unconscious and will die within seconds.

You'll start smelling it at about 0.1 ppm but at otherwise not lethal concentrations it will desensitise your nose and you will eventually not realise it's still around or getting stronger.

As a side effect it has a much wider range of explosiveness than regular hydrocarbon gasses and because it's heavier than air it will concentrate at low places.

Re:Yeah but... (1)

hughk (248126) | more than 6 years ago | (#22869776)

Many, many years ago before I moved into the 'safer' world of banking, I was involved with plat supervisory and management systems at a Petrochemical company. We often had to visit plant control rooms, which meant being uncomfortably close to the plant itself. It was always a favourite thing of the plant engineers to relate to us IT people how dangerous the stuff sitting in the plant was.

Given the fact that all plants leak over time, it was always one of the more interesting calls that a plant manager had to make was when the leaks were bad enough to warrant closing down the plant for maintenance. If the stuff leaking from the flanges wasn't explosive or highly toxic, it was usually at least inflammable and carcinogenic. Ironically one of the most dangerous things, accident wise was superheated steam.

" 'We don't know yet if these results will be transferable to humans, so our next step will be to study the use of hydrogen sulfide in larger mammals.' "

But hang on, I thought animals used in vivisection were supposed to be MODELS of humans, after all, mice are exactly the same as humans. Aren't they?

So how they're going to torture more animals, bigger ones, "larger mammals" as they call them. And get away with it. What if it were YOU being tortured?

Yet more fraudulent 'research' from the psychopaths otherwise known as vivisectionists...

EVERY single new drug or medical procedure that is now used successfully on human beings was TESTED on human beings - i.e. they EXPERIMENTED on humans. We know this because 92% of new drugs FAIL when they go through 'clinical trials' - (otherwise known as HUMAN EXPERIMENTS).

That's why the first human heart transplant recipients all DIED. I thought the animal experiments were supposed to predict human outcomes?

This 'research' is just more of the same- fucked up little geeks who got their asses kicked in high school, and like taking out their rage on innocent creatures who aren't big enough to fight back.

Gee... I wonder why they never do experiments on tigers or pit bull terriers? Anybody?

You could do more for humans if there weren't all these "ethical objections" to research which would probably kill people, or to making transgenic humans. Fortunately, only humans object to human research, (just as only mice and hippies object to mouse research) and so our human probing experiments are proceeding as planned.

'We don't know yet if these results will be transferable to humans, so our next step will be to study the use of hydrogen sulfide in larger mammals.'
Uhh, no. The next step is to determine if this is the kind of suspended animation that is good for anything. If the mice enter a reduced metabolic state and then, after 3 days, die, well that's not terribly useful for anything. If, however, the mice managed to live 10 times the usual rodent lifetime then that's something... not terribly great.. but something. Try to make it so the mice are recoverable after 1000x the usual lifespan and you might have something useful.

I think that's not what they had in mind (5, Insightful)

Moraelin (679338) | more than 6 years ago | (#22867358)

While that's insightful in its own right, from reading the summary, I get the impression that they're not aiming for the kind of suspended animation where you freeze someone for 1000 years and wake them up later. Doing that at room temperature would be kinda dangerous anyway, since if you slowed their immune system 10 times they'll rot alive sooner or later anyway.

I'm getting the impression that this is more for rushing you to a hospital when they picked you up half-dead and bled half-dry off the side of the road.

If you're in serious shock for example, if the other mechanisms still work, the body will try to keep the brain alive, even at the cost of cutting off oxygen supply to the other internal organs. Which decay very fast. (Muscles have their own oxygen reserves, so they tend to survive, your liver doesn't.) Cells run out of oxygen and essentially commit suicide in an orderly fashion, i.e., apoptosis [wikipedia.org] .

If it doesn't have enough even for the brain, which is often the case, the damage is irreversible and often fatal. Very fast.

So if they can slow your metabolism a lot, that might just give them extra time to haul you into ER. It might just turn that 5 minute rush before your brain starts getting massive damage, into, say, 50 minutes. Which might just do the trick.

I.e., briefly: it's not for colonizing Alpha Centauri, mate, it's just while they haul you to ER.

Well, I suppose they could stuff you full of this gas _and_ freeze you. I guess it just makes sense to solve it one step at a time anyway. It's probably enough work to find out what it does to a human and get it through FDA even at room temperature. They'll have time to worry about the freezing part after they get that sorted out.

I read recently (on /. I think) that it was discovered the tissue damage was done when RISING o2 levels triggered apoptosis. Meaning there is actually a period as long as 2hrs where little or no tissue damage has occurred. If the o2 levels can be brought up in a way that keeps the trigger from thinking a massive o2 spike is about to mutate all the DNA we might realize the dream of Herbert West. I also read about this a while back and they didn't think it would scale to humans, but if it did, it might stack nicely to allow delaying reanimation even longer.

Keep the bodies cold (not freezing) and let them sleep the entire way to Mars.

Hook them up to a vitamin packed IV, so they don't starve. Even at their slowed rate, two years is a long time.

Admittedly we might just do periodic wake ups so they can eat, stretch their muscles, and send status reports. The rate would just depend on the safety margin of the hibernation.

Although considering the current perception in the medical community of EMTs and Paramedics, it's very unlikely this will ever come to pass. Most Ambulances are BLS (basic life support) trucks with, at best, and EMT-Intermediate (or state equivalent) who in most jurisdictions can't hang a normal saline drip without begging medical direction. Perhaps they'd eventually allow paramedics on ALS rigs (often dispatched after a BLS rig has been on scene for a few minutes) to do something like this since it's vaguely similar to the sedation/paralysis of an RSI, but I just can't see any medical director authorizing what amounts to inhaled sedation in an ambulance without an omniscient and infallible Doctor on board.

Re:I think that's not what they had in mind (1)

sjames (1099) | more than 6 years ago | (#22870762)

As far as sci-fi style suspended animation, this isn't quite it. It will significantly reduce but not by any means stop metabolism. It could potentially be useful for months in space to reduce resources required, but certainly nothing like the frozen for 1000 years scenerio.

Medical uses are more likely. In addition to the emergency use you point out, it could also be useful for surgical procedures that aren't considered survivable today or perhaps to avoid some of the potential nasty effects of ECMO in a critical care situation. It might be easier on the patient's system to induce hypothermia than to force it with a blood cooler.

There are always places where harmful chemicals can be useful. Even if this causes damage/death after a few days/weeks/months, there are situations where it will prevent death that would occur in minutes.

Just off the top of my head, mines. Mandatory pressurized bottle w/ masks at every junction in a mine, in case of collapse (I'm thinking it *has* to be less explosive than storing bottles of pure oxygen). If it slows oxygen consumption to 25% (pulled out of my ass, because examples need numbers!) of normal, that gives rescue workers 4 times a long to dig out live bodies.

Once they are out, the hospitals/trained medical professionals can go about treating them for Crush Syndrome and for the poison that kept them alive by killing them slowly.

Assuming you can hit the right amount of hydrogen sulfide. If, on the other hand, everyone thinks they're going to die, and breathes deep in a panic, the rescue workers can bore their way into the still oxygenated chamber, and find that everyone died of hydrogen sulfide poisoning.

Re:No, that isn't the next step (0)

Anonymous Coward | more than 6 years ago | (#22869002)

Safe in a mine? H2S is (iirc from oilfield safety training) rated safe at 10ppm, unsafe at 15pm, causes permanent damage at 40ppm, lethal at 80 ppm. It'll kill in one breath at 400ppm and can be found in concentrations of thousands of ppm in oil wells. It also settles to the lowest point, pushing away oxygen, and is highly explosive. I don't know about comparing it to pure O2, but when concentrations of H2S get an open flame, it makes _craters_. Big ones. That said I expect something could probably be figured out to make it useful in a mine, but I would not want to test the first couple of versions.

Old News (5, Informative)

Smordnys s'regrepsA (1160895) | more than 6 years ago | (#22867404)

Can we get an update? There have already been tests involving pigs (lifted straight from the wikipedia [wikipedia.org] entry)

Induced hibernation

In 2005 it was shown that mice can be put into a state of suspended animation-like hypothermia by applying a low dosage of hydrogen sulfide (80 ppm H2S) in the air. The breathing rate of the animals sank from 120 to 10 breaths per minute and their temperature fell from 37 C to just 2 C above ambient temperature (in effect, they had become cold-blooded). The mice survived this procedure for 6 hours and afterwards showed no negative health consequences.[6] In 2006 it was shown that the blood pressure of mice treated in this fashion with hydrogen sulfide did not significantly decrease.[7]

Such a hibernation occurs naturally in many mammals and also in toads, but not in mice. (Mice can fall into a state called clinical torpor when food shortage occurs). If the H2S-induced hibernation can be made to work in humans, it could be useful in the emergency management of severely injured patients, and in the conservation of donated organs.

As mentioned above, hydrogen sulfide binds to cytochrome oxidase and thereby prevents oxygen from binding, which leads to the dramatic slowdown of metabolism. Animals and humans naturally produce some hydrogen sulfide in their body; researchers have proposed that the gas is used to regulate metabolic activity and body temperature, which would explain the above findings.[8]

However, a 2008 study failed to reproduce the effect in pigs, concluding that the effects seen in mice were not present in larger mammals. [9] [pccmjournal.com]

Read that paper about the pigs - they somehow expected a pig's body temperature to drop by several degrees in a couple of hours. H2S as an air-conditioner, now that would be cool!

(even dead pigs take a LONG time to cool off)

Best cure for a suspended mouse (2, Funny)

LiquidCoooled (634315) | more than 6 years ago | (#22867438)

If you have a suspended mouse, just check the ball hasn't got fluff on it.
For wireless mice, check the battery level and ensure its paired correctly with its base station.

Bah! I had a Dell desktop hooked up to a Microsoft ergonomic keyboard with all of those extra buttons once.

I once inadvertently hit the "Sleep" button. The machine went into a hibernate state that I couldn't get it out of. I asked our IT guy, and he said he's never found a way out of that state. The only solution (we could find) was to fully power off and cold boot.

I'm not convinced that suspend/sleep/resume is a feature that actually works on most machines. :-P

Hey, you are right of course.
I don't know about you, but whenever anyone farts nearby my metabolism slows right down and I practically stop breathing.
(of course running for the door/window is another alternative)

I never understood why scientists always assume that results obtained from tests with animals will automatically work for humans too. Cut this bullshit already!!

I can see it now. An elevator in a high rise office building reaches the main floor. When the door opens, a car full of unconscious people is revealed. Subsequent investigation proves that the exhaust fan failed two floors below a stop on Floor 99, where the offices of the Beerf, Art & Ghasper Pickled Egg & Sausage Supply, Ltd. are located.

I think the old saying was, "It's an ill wind that blows nobody good".

... some towns around the planet have quite a reputation for having a high sulphur rate in their atmosphere (Rotorua [wikipedia.org] in NZ is nicknamed "Sulphur City" because of that -- you can actually smell it when you're getting close to the town, and it takes a little while to get used to breathing that air !). Why don't they conduct a survey on the metabolism of the people naturally exposed to those gases ?

more cruel animal testing (-1, Flamebait)

Anonymous Coward | more than 6 years ago | (#22868376)

Yes, I know what you're going to say - "it's ok because it'll save human lives! the end justifies the means!"

Here's a clue. There's less competition for resources in a smaller population. Hitler's Final Solution was thus justified because it gave more space for Aryans, reducing their need to compete with Jews.

Some of you will cry "Godwin!". Well, Godwin isn't a law of physics, and each argument referencing Hitler or the Nazis needs to be judged on its merits, not by shouting "Gowdin!".

For those still reading, I'm sure I'll get a, "But Jews are worth more than rodents!" The response Hitler would have made is, "no, zey are worth precisely as much as rodents!" - hence the propaganda which compared them to rats etc.

Whether stranger humans are worth more than rats is a philosophical question; do we draw the line at family, at friends, at race, at species? A good quarter of British households, or more, invest more in a canine or feline than the proverbial starving African, so they've made the same judgment Hitler made.

There, you have it. Oh, and BTW :

Since we're talking about sulphur gases, it's "the end justifies the beans".

1. hydrogen sulfide = a TOXIC gas.
2. Mice are INHALING hydrogen sulfide.

So, they are inhaling a toxic gas? How can this be good for them?

I heard that arsenic is a good preservative too.

Tunneling Rodents (0)

This could be mouse-specific. After all, they are tunneling rodents and tunnels are sometimes temporarily gas-filled.

It could be just an adaptation: "Oh-Oh! Bad air! Let's shut down and wait it out."
