Outline of Final Research Achievements

Injection of Lipopolysaccharide（LPS）from E.coli could cause septic acute kidney injury with decrease in urinary output and increase in serum creatinine.
The oxygen partial pressure at surface area in the kidney where there were numerous of glomeruli did a little change during sepsis. The glomeruli did not show histological change.On the other hand, the oxygen partial pressure at deep area in the kidney where there were numerous of tubules did more change during sepsis compared with the surface area. The tubules did show histological change.
However, there was no significant correlation in changes between blood pressure and oxygen partial pressure in both deep and surface area in the kidney. In sepsis induced by injection of LPS, injury of tubules might be a main cause,　which did not need to require decrease in oxygen partial pressure.
