Article Citation - Scopus: 2Platanus Orientalis (Plane Tree) Extract Protects Against Hyperoxaluria Induced Kidney Damage(Marmara University, 2022) Ayaz Adakul, B.; Şen, A.; Şener, T.E.; Erdoğan, Ö.; Çevik, Ö.; Eker, P.; Şener, G.; Ertas, Büsra; Çetinel, Şule; Bölükbaşı, Furkan; Şenkardeş, İsmailThe aim of this study is to determine whether Platanus orientalis (PO) which has anti-inflammatory, antioxidant and diuretic properties and used in the treatment of kidney stones as traditional folk medicine, will reduce or prevent the stone formation in the urinary system. To simulate the urolithiasis model 0.75% ethylene glycol (EG) and 1% ammonium chloride (AC) were applied to Sprague-Dawley rats. The rats were divided into four groups (n=8). The control group was given standard drinking water for 5 weeks. EG group received 0.75% EG in their drinking water containing 0.75% EG and 1% AC. PO extract (100 mg/kg) was given orally for 5 weeks to the preventive group and for last 2 weeks to the therapeutic group, respectively. At the end of experiment, 24-hour urine and kidney samples were obtained. In urine samples, calcium and citrate levels were decreased and oxalate level was increased in the EG group. In kidney samples myeloperoxidase, caspase-3, N-acetyl-β-glycosaminidase (NAG) activities, malondialdehyde (MDA), 8-hydroxy-2-deoxyguanosine (8-OHdG), tumor necrosis factor-α and interleukin-1β levels were increased while superoxide dismutase activity and glutathione levels were decreased in the EG group. These biochemical parameters returned to control levels in both PO treatment groups. Histological findings also correlate with these results. Our findings are suggested that PO treatments is effective in both preventive and therapeutic groups. © 2022 Marmara University Press.Article Citation - WoS: 1Histological and Biochemical Effects of an Ethanolic Extract of <i>myrtus Communis</I> Leaf on the Pancreases of Rats Fed High Fat Diets(Taylor & Francis Ltd, 2024) Kabatas, Gul Sinemcan; Ertas, Busra; Sen, Ali; Sener, Goksel; Ercan, Feriha; Akakin, DilekWe investigated the effects of an ethanolic extract of Myrtus communis subsp. communis (MC) leaves on the pancreases of rats fed with a high fat diet (HFD). Wistar albino rats were fed either with standard lab chow (Control group) or with a 45% fat diet (HFD and HFD+MC groups) for 4 months, with the MC extract (100 mg/kg) being administered by orogastric gavage to rats in the HFD+MC group during the last month. Blood and pancreas samples were collected from all experimental groups at the end of the study. Insulin and leptin levels, and the lipid profile, were analyzed in the blood serum. Pancreatic injury was assessed histologically. Insulin, nuclear factor kappa beta (NF-kappa B), and alpha-smooth muscle actin (alpha-SMA) were assessed using immunohistochemistry. Apoptosis was assessed using terminal deoxynucleotidyl transferase dUTP nick end-labeling (TUNEL) immunohistochemistry. In addition, oxidant/antioxidant activity was analyzed by biochemical methods. Increased body weight, serum insulin and leptin levels, blood glucose level and pancreatic tissue malondialdehyde (MDA), 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels, myeloperoxidase (MPO) activity and decreased tissue glutathione (GSH) level were observed in the HFD group compared to the Control group, in addition to dyslipidemia. An increased histopathological damage score, pancreatic islet area, insulin, TUNEL, NF-kappa B and alpha-SMA immunoreactivity were seen in animals from the HFD group compared to the Control group. However, such pathological changes were reduced in the HFD+MC group. Our data indicate further investigation of MC extract as a therapeutic adjuvant for HFD-induced pancreatic injury, acting via anti-inflammatory and antioxidant mechanisms, is worth carrying out.
