Japan: Study of biological artificial kidneys

Researchers from Japan Tokai University have studied a type of 'bio-artificial kidney', this type of kidney with a small volume, easy to transplant not only has the function of resolution and elimination as kidneys of people It also has the function of preserving useful components.

This type of artificial biological kidney mainly consists of two main parts.

The first is the "Artificial kidney" function that filters water and waste from the blood.

The second part is the "artificial urethra" that brings useful ingredients like water and a-min acid back into the urine.

Renal and artificial urethra are made in the form of silk fibers.

The inside of "artificial urethra" is also covered with a layer of skin cells that functions to disintegrate waste. The inside of the filaments in the kidney is used by pig skin cells

This type of skin cell can bring beneficial substances like glucose, vitamins and minerals back into the blood.

The previous type of artificial kidneys can only filter wastes by osmosis, not function to bring components like a-acid acid back into the blood.

Researchers have conducted this new artificial kidney transplant on chamois.

After two weeks, researchers confirmed that artificial kidneys began to function.

Currently, they are studying bio-artificial kidneys for humans, after certifying safety will conduct clinical experiments, in the future, this may be good news for patients with disease. kidney.
