    Evaluation of Genotoxicity Risk in Health Care Workers Exposed to Antineoplastic Drugs
    (MARMARA UNIV, INST HEALTH SCIENCES, 2019-06-30) BECEREN, AYFER; Oltulu, Cagatay; Yesil Devecioglu, Tugce; Akinci, Melek; Olmez, Sevcan Gul Akgun; Obeidin, Serra Vildan Akgul; Beceren, Ayfer
    Objective: DNA damage that can be caused by workplace exposure to antineoplastic drugs in health workers has been shown in many scientific studies. It is aimed to evaluate whether the risk of genotoxicity in health workers decreases after the regulations and measures taken by national and international health authorities in our work. Methods: For this purpose, DNA damage was assessed by using alkaline comet technique in lymphocytes isolated from blood samples of health workers (n=29) who were involved in preparing and/or administering antineoplastic agent at Trakya University Health Research and Application Center and compared with the control group (n=30). Also, those who prepare and/or administer antineoplastic agents; (n=16) and manual (n=13) preparations. Results: As a result of the evaluation, there was no statistically significant difference between health personnel and control group in preparing and / or administering antineoplastic agent (p>0,05, Mann-Whitney U) and there was no difference in the genotoxic risk between preparation forms. Furthermore, when the exposed control group was assessed for DNA damage as smokers and nonsmokers, there was no statistically significant difference in terms of DNA damage (p>0.05). Conclusion: At the center where our samples were taken, the resulting measures resulted in the control of the risk of genotoxicity due to occupational exposure to antineoplastic agents.

    OBJECTIVE: Nerium oleander (Apocynaceae) and Aloe vera (Liliaceae) are among the widely used herbal remedies for treating skin diseases and possess numerous activities such as antibacterial, antiviral, antifungal, and antioxidant. The aim of this study was to investigate the possible wound healing effect of Aloev era-based extract of the N. oleander leaf (NAE-8 (R)) based on its antioxidant, anti-inflammatory, and DNA repair capacity along with histological changes and to compare them with the traditional silver sulfadiazine treatment (SSD). METHODS: Twenty-four Wistar albino rats were randomly grouped as follows: i) control, ii) burn alone (burn), iii) burn with topical NAE-8 (R) (burn+ NAE-8 (R)) treatment, and iv) burn with topical 1% silver sulfadiazine (burn+ SSD) treatment. All groups received their related topical application twice a day for 14 consecutive days. Upon completion of the experimental protocol, trunk blood and skin tissues were collected for measuring malondialdehyde (MDA), glutathione (GSH), myeloperoxidase (MPO), tumor necrosis factor alpha (TNF-a), interleukin-1 beta (IL-1 beta), % DNA in the tail (% DNAT) levels along with histological examinations. RESULTS: Thermal injury-induced alterations in MDA, GSH, MPO, TNF-a, IL-1 beta, and % DNAT levels were significantly reversed by NAE-8 (R) treatment. These ameliorative effects were also supported by histological findings. CONCLUSION: Findings of the present study suggest that NAE-8 (R) is a promising remedy for treating skin burn injury.
