Researchers from Japan's National Defense Medical College report they have developed an artificial blood substitute that shows comparable efficacy to normal blood in saving exsanguinated rabbits.

When the artificial blood was tested on 10 rabbits suffering from serious blood loss, six of them survived, a ratio comparable to that among rabbits treated with real blood, according to the team.

No negative side effects, such as blood clotting, were reported, the researchers said.

The blood substitute was developed by combining "previously developed substitutes for red blood cells (RBCs) and platelets (PLTs) for transfusion", it can also be stored for over a year un-refrigerated (whole blood can only be stored for about 20 days, and platelets only 4 days.) The artificial blood does not suffer from blood-type rejection issues allowing earlier interventions and

injured patients can be treated before they arrive at hospitals, resulting in a higher survival rate, the team said.

Imagine a future in which seeing "The Red Cross" pop up on their phones doesn't make people instinctively attempt to cover and protect their inner arms.

    Japanese scientists invent "Tru Blood", you say?

    Now the only thing that was any good about that series was the leading woman was hot, but still...

      I remember withdrawing off The Masquerade – Bloodlines reading the novels and, from the weekend+ binging I can barely remember, the first couple of novels were decent enough. Problem was they dragged on (as most successful series do) and the romantic twist and turns just couldn't keep up with the (similarly degrading) plot.

      From the little I recall from the few episodes I watched, the TV adaptation broke off from the original plot line in a failed attempt to salvage it.

      Anyhow, there's a Masquerade – Bloodlines 2 on the way but I haven't gamed in years... Maybe I'll catch the novel adaptation or something :D

    No negative side effects, such as blood clotting, were reported, the researchers said.

    While it wasn't blood clotting, I am sure that 4 in 10 rabbits would not agree with the no negative side effects. (Or they would, if they were still around to disagree.)

      Wait for the human tests... guess which underprivileged race will be over-represented in the test groups. It's one way of reducing Democrat voter lists.

        Pure bullshit.
        Overwhelmingly, it is white people who volunteer (maybe for some money) for medical experiments. You even have the medical research community trying to address the "injustice" that our medicine works best on white people as a result!

      They suffered a side effect from being beaten to a pulp by callous researchers.

    Sounds like the liposome sheath that covers the blood cells prevents detection of a potential immune system mismatch, but they don’t come out and say that in TFA.

    tested on 10 rabbits suffering from serious blood loss

    I shudder to think how they obtained such rabbits.

    I shudder even more to think what they'll do, when they proceed to testing on humans. Premeditated murder? (But 60% of the victims survived, Your Honor!) They were only [name your favorite non-US nation] wounded POWs? Denying real blood transfusions to accident victims, so that they can test the artificial variety?
