    Objectives: 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>

    Effects of <i>myrtus Communis</I> L. Extract and Apocynin on Lens Oxidative Damage and Boron Levels in Rats With a High Fat-Diet
    (Galenos Publ House, 2021) Yasar, Ruya Kuru; Kuru, Dilruba; Sen, Ali; Sener, Goksel; Ercan, Feriha; Yarat, Aysen; Kuru, Ruya
    Objectives: Nutritional obesity causes oxidant damage in the body and cataract formation in the lenses by increasing the formation of free radicals. Myrtus communis leaf extracts (Myr) have antioxidant properties, and apocynin (Apo) is an effective NADPH-oxidase inhibitor. The data on tissue boron levels are quite lacking. The aim of this novel study was to investigate the effects of Myr and Apo treatment on boron levels and oxidative lens damage in rats fed a high-fat diet (HFD). Materials and Methods: Wistar albino male rats were randomly divided into four groups: the control group, HFD group, HFD + Myr group, and HFD + Apo group. Body weight and blood lipids were determined before and after the experiment. After decapitating the rats, the lenses were removed and homogenized. Catalase (CAT) and superoxide dismutase (SOD) activities and boron, malondialdehyde (MDA), and reduced glutathione (GSH) levels in the lens homogenates were determined. Results: The HFD increased serum triglyceride (p<0.05), total cholesterol level (p<0.001), body weight (p<0.001), and lens MDA levels (p<0.01) and decreased lens GSH (p<0.05) and boron level (p<0.01), SOD (p<0.001), and CAT activity (p<0.001). However, Myr and Apo treatment reduced the rats' body weight (p<0.001), serum triglyceride (p<0.05), and total cholesterol level (p<0.001) and increased lens boron (p<0.01; p<0.001), GSH levels (p<0.05; p<0.01), and CAT activity (p<0.001). Conclusion: Both Myr and Apo may be able to reduce oxidative stress in the lenses of obese rats caused by HFD by increasing boron levels.
