Kidney disease is diagnosed by measuring urinary catalytic iron in humans. Progressive kidney disease is treated by administering an iron chelator to humans. In particular, the progression of kidney disease essentially can be halted and the severity of kidney disease can be reduced by the administration of iron chelators to humans afflicted with a progressive kidney disease. The methods include measuring catalytic iron content in urine in a human afflicted with a progressive kidney disease and administering an iron chelator to the human. The method can include measuring total urinary protein content, blood urea nitrogen or creatinine in a blood sample before, during or after the administration of an iron chelator.

The invention discloses a construction method of a human nerve stem cell bank. The method comprises the following steps: carrying out human urine separation to obtain human kidney epithelial cells, subculturing the human kidney epithelial cells, partially cryopreserving the human kidney epithelial cells, inducing the subcultured human kidney epithelial cells to form nerve stem cells, separating the nerve stem cells obtained after induction, carrying out amplification culturing, identifying the nerve stem cells, cryopreserving the confirmed nerve stem cells, coding and warehousing. The method avoids the use of fetal bovine serum in the whole process, eliminates the introduction of foreign proteins, and reduces hidden troubles; the method allows the successfully induced stem cells with activity to be preserved in order to form the bank, and the stem cells can be provided for clinic use within 3d; and a cryopreservation mode in the method is characterized in that nerve bulbs with a certain size are cryopreserved, a protection agent is introduced step by step in the cryopreservation process, and the cooling rate is set in grading, so recovered nerve stem cells still have high cell viability and activity, and have significantly higher than cell viability and activity than the recovered nerve stem cells preserved through current routine slow low-temperature cryopreservation methods.

An implantable human kidney replacement unit. Fully functional self contained, providing patients with end stage renal disease the freedom of traveling and moving about normally. Replacing donor kidneys. Implanted in the flank with at least one inlet and outlet tube each, sutured to the iliac artery and vain, at least one urine tube to the ureter. The housing constructed of anti-coagulant bacteriostatic materials has a plurality of reverse-osmosis process chambers with semipemeable membranes through the unit, followed by osmosis-diffusion chambers and membranes. Blood from the artery enters the first of the chambers. Small molecules such as water, magnesium, sodium, potassium, calcium, urea etc. are extracted from the blood according to their weight in atomic mass units as blood wipes past the self-cleaning membrane cartridges in the chambers. Molecules are further separated and urea sent to the bladder with excess water and electrolytes. The remainder is channeled to at least one diffusion chamber and reabsorbed into the blood. The same process is repeated in the other chambers where selected larger molecules such as creatinine and phosphorus are excreted, and some diffused back into the blood.

The invention provides a kidney surgery model capable of simulating blood circulating and urine generating functions.
