ABSTRACT
<p><b>OBJECTIVE</b>To establish a kidney deficient aging model (KDAM), assess it in antioxidant capacity, HPAT axis function and bone metabolism, and compare with D-galactose aging model.</p><p><b>METHOD</b>Aging rat model was established by injecting D-galactose solution, meanwhile dexamethasone solution was injected to establish kidney deficient aging model. Then these models were evaluated by serum MDA (malondialdehyde) and GSH-Px (glutathione peroxidase), liver SOD (superoxide dismutase), adrenal, thymus and spleen index, CD4(+), CD8(+), and serum COR (cortisol), BGP (bone Gla-protein), plasma ACTH (adrenocorticotropic hormone) and CRH (corticotropin-releasing hormone).</p><p><b>RESULT</b>Compared with the normal group, the aging model group and the kidney deficient aging group showed significant decrease in liver SOD activity (P < 0.01 on average) and significant increase in serum MDA content (P < 0.01 on average) , and the kidney deficient aging group revealed remarkable decline in plasma ACTH content (P < 0.05). Compared with the normal group and the aging model group, the kidney deficient aging model group's weight, serum GSH-Px decreased (P < 0.01, P < 0.05), adrenal index decreased (P < 0.05, P < 0.01), serum COR decreased (P < 0.05 on average), plasma CRH increased (P < 0.05, P < 0.01), serum BGP content significantly decreased (P < 0.01 on average), value of CD4(+), CD8(+) decreased (P < 0.05, P < 0.01), CD4(+)/CD8(+) increased, but without significant difference.</p><p><b>CONCLUSION</b>The kidney deficient aging model shows significant decrease in antioxidant capacity, dysfunction of HPAT axis disorder and abnormal bone metabolism. However, D-galactose aging model only shows a significant difference in antioxidant capacity.</p>
