Publication Open Access Myrtle improves renovascular hypertension-induced oxidative damage in heart, kidney, and aortic tissue(2022-07-01) ŞEN, ALİ; ŞENER, GÖKSEL; AKBAY, TUĞBA; Arslan S., Ozcan O., Gurel-Gokmen B., ÇEVİKELLİ YAKUT Z. A., Saygi H. I., ŞEN A., GÖGER F., ERKANLI ŞENTÜRK G., Sener G., Tunali-Akbay T.Renovascular hypertension is defined as the reduction in renal perfusion resulting in sustained hypertension. This study aims to investigate the possible effects of myrtle leaf extract (Myrtus communis L.) on, heart, kidney and aorta tissues in the experimental renovascular hypertension (RVH). 32 male Wistar Albino rats were divided into four groups as control, hypertension, hypertension+ramipril, and hypertension+myrtle leaf extract treatment groups. RVH model was induced by Goldblatt\"s 2-kidney 1-clip method. 12 weeks later than the treatment blood pressures were recorded and oxidant and antioxidant parameters, tissue factor activity, and histological analysis were determined in the kidney, heart, and aortic tissues. The blood pressure levels of the hypertension group significantly increased compared to the control group. Administration of myrtle leaf extract and ramipril significantly decreased the increased blood pressure. In the hypertension group, oxidative damage increased in the kidney, heart, and aorta tissues. In the histological evaluation of tissues in RVH, heart muscle fibres degenerated. Bowman capsule and glomeruli dilated and tubules damaged in the kidney. Myrtle leaf extract administration regenerated the damages and degenerations. The administration of myrtle leaf extract restored the impaired oxidant-antioxidant balance in the heart, kidney and aorta tissues of hypertensive rats. Myrtle leaf extract can be considered as an alternative antihypertensive treatment target in the prevention of oxidative stress-induced damage in renovascular hypertension.Publication Metadata only Protective effect of Myrtle (Myrtus communis) on burn induced skin injury(ELSEVIER SCI LTD, 2019) ŞEN, ALİ; Ozcan, Ozan; Ipekci, Hazal; Alev, Burcin; Ustundag, Unsal Veli; Ak, Esin; Sen, Ali; Alturfan, Ebru Emekli; Sener, Goksel; Yarat, Aysen; Cetinel, Sule; Akbay, Tugba TunaliThermal skin burns cause local injury as well as triggers acute systemic inflammation response where the imbalance between oxidative and antioxidative system occurs. As an alternative treatment, various medicinal herbs are used to treat burn injuries in many countries. In this study, the possible protective role of oral or topical Myrtle (Myrtus communis L.) treatment against burn-induced damage was investigated. The dorsum of the Wistar Albino rats was shaved and exposed to 90 degrees C water bath in burn group or 25 degrees C water bath in control group for 10 s under ether anesthesia. Myrtle extract was applied 100 mg/kg/day for 2 days either orally or topically. In skin samples; malondialdehyde and glutathione levels, catalase, superoxide dismutase, nitric oxide and tissue factor activities were determined. Skin tissues were also examined by light microscopy. Severe thermal skin bum injury caused a significant decrease in glutathione level, superoxide dismutase, catalase and tissue factor activities as well as nitric oxide level, which was accompanied with significant increases in skin malondialdehyde level. Myrtle treatment reversed all these biochemical indices except topical Myrtle treated group's nitric oxide level, as well as histopathological alterations, which were induced by thermal trauma. Both oral and topical Myrtle extract treatment was found to have protective role in the bum induced oxidative injury, which may be attributed to the potential antioxidant effect of Myrtle. As a conclusion, Myrtle significantly diminishes burn-induced damage in skin. (C) 2019 Elsevier Ltd and ISBI. All rights reserved.
