Article In Vivo Antioxidant and Anti-Inflammatory Effects of Myrtus Communis Against Ionizing Radiation-Induced Gastrointestinal Injury: Trod-Grog Study(Kare Publishing, 2025) Kilic, Melisa Bagci; Varan, Melike Pekyurek; Atasoy, Ozum; Ozyilmaz, Nagehan; Pazarbasi, Seren Ede; Ertas, Busra; Atasoy, Beste Melek; Ercan, FerihaOBJECTIVE: This study aimed to investigate the in vivo radioprotective effects of Myrtus communis (MC) on the gastrointestinal system. METHODS: A total of 30 female rats were divided into four groups: i) Control; ii) irradiation (IR) only; iii) MC-pretreated; and iv) MC-treated. The rats received oral MC extract (100 mg/kg/day) for 4 days before exposure to 10 Gy IR or continued until sacrifice. On the fourth day of IR exposure, the rats were sacrificed, and histopathological and biochemical analyses were performed on the ileum, pancreas, and liver tissues. RESULTS: Malondialdehyde and myeloperoxidase levels decreased in both MC-treated groups, while glutathione levels and Na+-K+-ATPase activity increased (p<0.01), with significant histopathological improvements compared to the IR-only group. CONCLUSION: The results of this study demonstrate that MC significantly decreases ionizing radiation-induced oxidative and inflammatory damage in the gastrointestinal systems of rats. Therefore, it may be regarded as a new candidate with radioprotective potential for future clinical application.Article Myrtus Communis Ameliorates Ionizing Radiation-Induced Cardiopulmonary Injury in Rats: Trod-Grog Study(Keai Publishing Ltd, 2026) Aytekin, Aynur; Isci, Oguzhan; Ozyilmaz, Nagehan; Karaoglu, Sumeyye Yilmaz; Ertas, Busra; Sen, Ali; Atasoy, Beste Melek; Yılmaz Karaoğlu, SümeyyeObjectives: Ionizing radiation (IR), widely used in diagnostic and therapeutic procedures, can damage vital organs such as the heart and lungs through oxidative stress. This study aims to assess the potential radioprotective effect of Myrtus communis (MC) against cardiopulmonary injury. Methods: Thirty female rats were divided into four groups. Control (C) and IR (R) groups received oral saline. The treatment (R+MC) and pretreatment (R+preMC) groups received MC (100 mg/kg) for 4 days (starting on the day of IR) and 8 days (starting 4 days before IR), respectively. All IR-exposed groups (R, R+MC, R+preMC) received a single 10 Gy whole-body irradiation. Histopathological changes were assessed by hematoxylin-eosin staining, while oxidative stress was evaluated by measuring malondialdehyde (MDA), glutathione (GSH), myeloperoxidase (MPO), nitric oxide (NO), superoxide dismutase (SOD), glutathione S-transferase (GST), and tissue factor activity (TFa) levels. Protein profiles in tissues were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Results: Histopathologically, MC reduced alveolar and cardiomyocyte damage in both R+MC and R+preMC groups. IR increased all oxidative stress markers and decreased antioxidant parameters in heart and lung tissues (p < 0.05-0.001). Both MC treatment and pretreatment reversed these effects, significantly reducing oxidative/inflammatory markers and restoring antioxidant enzyme activities (p < 0.05-0.001). The R+preMC group demonstrated a stronger protective effect than the R+MC group. Conclusion: Our study shows that MC has a radioprotective effect on the cardiopulmonary system by decreasing oxidative damage. MC appears to be a promising natural compound for advanced radioprotection research, and further molecular and clinical studies could clarify its mechanisms and potential applications<bold>.</bold>Article Citation - WoS: 1Neuroprotective Effect Of<i> Myrtus</I><i> Communis</I> Against Ionizing Radiation-Induced Brain Injury: Insights From Histopathological and Biochemical Analysis in Rats(Elsevier, 2024) Aslan, Dicle; Alan, Burcu; Yay, Nagehan Ozyilmaz; Karaoglu, Sumeyye Yilmaz; Ertas, Buesrara; Sen, Ali; Atasoy, Beste M.Aim: To investigate the potential radioprotective effects of Myrtus communis on brain tissue. Methods: Thirty female rats were divided into four groups. The control group (C) was applied with oral saline solution (SF) for four days. Myrtus communis (MC) groups started to receive MC (100 mg/kg, oral) either four days before (R + preMC) or immediately after (R + MC) irradiation for four days. Irradiation was applied 10 Gy in a single fraction. All rats were sacrificed on the fourth day of irradiation. Malondialdehyde (MDA), nitric oxide (NO), and glutathione (GSH) levels, myeloperoxidase (MPO), superoxide dismutase (SOD), and tissue factor activities (TFa) were determined for biochemical analysis. Hematoxylin&Eosin &Eosin staining was done for histopathological analyses, and electrophoretic analyses were performed. Results: NO, MDA, and MPO levels were higher in all irradiated groups compared with the C group. MC administration decreased NO, MDA, and MPO levels in R + preMC and R + MC groups. MC administration increased GSH levels. TFa activity decreased in R groups but did not change with MC administration compared to the C group. Radiation-induced brain tissue injury decreased, and morphologically normal neurons were observed in both MC-added groups. Conclusion: Myrtus communis has a potential neuroprotective effect on brain tissue, attributed to its antioxidative, anti-inflammatory, and anti-lipid peroxidative properties.Article The Protective Effects of Myrtus Communis Subsp. on Ovariectomized Diabetic Rats’ Renal and Intestinal Tissues: in Vivo and in Silico Approaches(Taylor and Francis Ltd., 2025) Ertik, O.; Kadıoğlu-Yaman, Beril; Şen, Ali; Şener, Göksel; Yanardag, RefiyeIntroduction: Postmenopausal diabetes is a condition that affects millions of women and their quality of life. Also, kidney and small intestine tissues are damaged due to diabetes. The present study aimed to examine the protective effects of an extract prepared from Myrtus communis leaves on kidney and small intestine tissues against experimentally created postmenopausal diabetes. Methods: For this purpose, experimental rats were randomly divided into six groups (Control; ovariectomy:OVX, diabetic:D, ovariectomy + diabetic:OVX + D, ovariectomy + diabetic + oestrogen:OVX + D+E2, ovariectomy + diabetic + MC: OVX + D+MC) and kidney and small intestine tissues were taken after the experimental procedure. Results: Evaluations of biochemical parameters (glutathione and glutathione-related enzymes, antioxidant enzymes, etc.) showed that MC had a protective effect on kidney and small intestine tissues in diabetes and ovariectomy groups. Conclusion: It can be suggested that MC extract has a protective effect on small intestine and kidney tissues in postmenopausal diabetes and may be a good herbal source for this purpose. © 2024 Informa UK Limited, trading as Taylor & Francis Group.
