Article Citation - Scopus: 2Effects Of Exercise And Calorie Restriction On Brain And Testis İn Natural Aging Model;(Istanbul University Press, 2021) Hakgüder, U.; Üstündağ, Ü.V.; Tüzüner, B.A.; Genç, N.; İpekci, H.; Özçelik, R.; Emekli-Alturfan, E.; Kahraman, Nevin Genc; Alev-tuzuner, Burcin; Şener, Göksel; Yarat, AysenThe aim of our study was to examine the effects of exercise and calorie restriction on various tissue damage and antioxidant parameters in the brain and testis of rats in a natural aging model. For this purpose, male Sprague-Dawley rats were the control group (C), the elderly (A), the elderly with calorie restriction (ACR), the elderly who were exercised (AE) and the elderly who were exercised with calorie restriction (ACRE), they were divided into 5 groups. The control group was composed of three-month-old animals. The other group consisted of 15-month-old rats. Exercise and calorie restriction were applied for 6 weeks. At the end of the experiment, lipid peroxidation (LPO), nitric oxide (NO), glutathione (GSH) levels and superoxide dismutase (SOD), catalase (CAT), glutathione-S-trans-ferase (GST) and tissue factor (TF) were determined in brain and testicular tissues homogenates. As a result of the study, the A group’s brain and testis LPO, NO levels and TF activity increased, GSH levels and SOD, CAT and GST activities decreased, when compared to the C group. As a result of our study, an increase in oxidant damage was observed with TF activity in the brain and testis in the natural aging model, and positive effects of exercise and calorie restriction on the antioxidant levels in the brain were determined, especially in aging. © 2021, Istanbul University Press.

This study aimed to investigate the changes in the brain after EX and/or CR in metabolic syndrome (MeS) induced by a high fructose diet in rats. Sprague-Dawley male rats were divided into five groups. Drinking water including 10% fructose solution was given to rats for 12 weeks to develop a MeS rat model. Animals with MeS were submitted to EX and/or CR for 6 weeks. Blood glucose, and brain tissue damage and antioxidant parameters were measured. Brain lipid peroxidation, sialic acid, mucin, fucose levels increased in the MeS group compared to the control (C) group. These parameters reduced significantly in the metabolic syndrome with caloric restriction (MeS+CR) group, and more significantly in the metabolic syndrome with exercise and caloric restriction group (MeS+EXCR), compared to the MeS group. Glutathione levels, superoxide dismutase and catalase activities decreased in the MeS group compared to the C group, increased both in the MeS+CR group, and MeS+EXCR group compared to the MeS group. High fructose diet consumption can lead to brain tissue damage and decreased antioxidant levels were found to be improved best in the MeS+EXCR group.
