Japanese scientists successfully tested artificial blood on rabbits

The good news once again raises hopes for a miraculous artificial blood, which can help save lives in times of need without worrying about anemia nowadays.

People are still trying to find what is called artificial blood to make it easier to treat injuries. However, how to create artificial blood that can carry oxygen and safely to humans is still a distant goal with science today.

There have been many studies on blood substitutes based on hemoglobin. Although these studies are evaluated very promisingly, the fact has proved that they are very toxic to organs in the human body.

Japanese scientists have created red blood cells and artificial platelets.

Of course, scientists have never stopped hoping to find a replacement for blood and platelets to save lives. And in such a search effort, Japanese scientists began to see "light at the end of the road".

According to the Asahi Shimbun daily, scientists at Japan National Defense University Hospital have successfully developed and tested artificial blood on rabbits.

The team of Japanese doctors including Kohsuke Hagisawa, Manabu Kinoshita, Masato Takikawa, Shinji Takeoka, Daizoh Saitoh, Shuhji Seki and Hiromi Sakai are the ones who have created red blood cells and platelets. These include oxygen carriers and hemostatic substances, all encapsulated in vesicles called liposomes. When they gave blood to severely injured rabbits, six of the ten rabbits survived. That's a relatively high survival rate for rabbits given a blood transfusion that is not true blood.

In particular, rabbits that receive blood transfusions do not have any clotting or any other negative side effects.

Artificial blood can be stored at room temperature for more than a year and is independent of blood type.

Normally oxygen-carrying red blood cells can only be stored at low temperatures for about 20 days. While platelets can only survive at room temperature for up to 4 days. In addition, emergency technicians are also unable to perform blood transfusions without knowing the patient's blood type.

But with this artificial blood, it can be stored at room temperature for more than a year and is independent of blood type. If commercialized, hospitals can use it to infuse patients without worrying about anemia, thereby significantly reducing mortality.

" There are remote islands and other areas that cannot access and distribute blood. With artificial blood, we can save lives, " said Manabu Kinoshita, a professor at Japan's Defense Medical University . people who were previously thought to be unable to save . "

The research was recently published in the Journal of Transfusion of the American Blood Bank Association.
