Özet

Aging is a progressive degeneration process in living organisms. Deprenyl is an irreversible monoamine-oxidase B inhibitor which has antioxidant, antiapoptotic and neuroprotective effects. Estradiol is also a neuroprotective and antioxidant hormone. The objective of this study was to determine whether the antioxidative effects of deprenyl can suppress apoptotic activity, with or without estradiol, in aged female rat kidney. Wistar Albino female rats were divided into six groups as follows; young (3 months old) control, aged (24 months old) control, aged deprenyl treated, aged estradiol treated, aged deprenyl plus estradiol treated and sham. All rats except for the sham group were injected for 21 days. Determination of oxidative stress parameter was performed spectrophotometrically. To detect apoptotic cells, TUNEL staining and caspase-3 immunohistochemistry were performed. Deprenyl and estradiol administration, alone or in combination, decreased significantly the levels of lipid peroxidation relative to aged control and sham-injected rats. The number of TUNEL positive cells decreased significantly in deprenyl and estradiol-treated rats compared with aged control and sham rats. Deprenyl and estradiol replacement attenuated age-related changes in renal morphology. The results indicate that deprenyl treatment alone, or in combination with estradiol, may modulate age-related apoptotic changes in rat kidney by decreasing oxidative stress.
