| Research Abstract |
The outcome to this research task was as follows. In the CKD model (5/6 nephrectomy), MK expression increased in a lung. In vitro,the amount of production of MK decreased by transfection of MK-siRNA into endothelial cells. Although the mouse was made to breathe in this siRNA, MK expression did not decrease. In another CKD model (L-NAME administration +Uninephrectomy), blood pressure did notelevated in MK deficient mice. there was no difference of ACE expression in serum or a lung between wild type mice and MK defficent mice. In the AKI model (bilateral IRI model and bilateral uninephrectomy), the change on neutrophil infiltration and edema was obserbed inthe lung. In the low oxygen exposure experiment which used the renal tubular cells, intracellular MK expression did not increase but the amount of production of MK in serum increased temporally. In the new ARDS/ALI patients, , mortality rate in the non-AKI group increased significantly rather than the AKI group as the long period of time of respirator management.
