    Effects of Curcumin and Doxorubicin on the Viability of Neuroblastoma Cancer Cell Line
    (2024) Ünlü, İlker; Ozdemır, Ilhan; Öztürk, Şamil; Tuncer, Mehmet Cudi
    Aim: Neuroblastoma has a very important place among childhood diseases, and despite all the methods used in treatment, it is very difficult to prevent neuroblastoma invasion. The number of studies showing that curcumin, the most active component of turmeric, is not toxic, is increasing day by day. In this study, the anticancer activities of curcumin (Cur), one of the important active compounds, were demonstrated in the Neuroblastoma cancer cell line (Na2B). Method: Neuroblastoma cell line was used in the study. To determine the IC50 doses of Dox and Cur, Na2B cells line were cultivated with an automatic pipette. MTT analysis was performed to analyze cell survival (viability). Inhibition levels in the cells were determined at 24 and 48 hours. Results: While the IC50 of Na2B cell proliferation was approximately 124.5 uM at the 48th hour in Dox-treated cells, the IC50 value of Cur at the 48th hour was found to be 224.6 uM. Conclusion: These results showed that Cur could be an alternative agent in the treatment of neuroblastoma, and its fewer side effects compared to other chemotherapeutic agents such as Dox would increase its preferability.

    Histopathological Changes in The Spinal Cord Tissue of Rats Administered an Experimental Mussel Diet
    (2024) Ünlü, İlker; Özdemir, Ilhan; Tuncer, Mehmet Cudi; Öztürk, Şamil
    Aim: Regional eating habits show that it causes neurodegenerative problems due to heavy metals that can accumulate in consumed foods and affect tissues such as the nervous system. Since crustaceans such as mussels feed by filtering the water, they are exposed to toxic plankton and various chemicals, especially heavy metals. Due to the limitations of experimental studies on this subject, the effects of mussel consumption on the spinal cord were investigated. Methods: In this study, histopathological changes in the spinal cord tissue of rats fed with shellfish collected from the Dardanelles were determined. The subjects were divided into two groups, and the first group was fed standard rat food for 4 weeks, and the second group was fed a mussel diet. At the end of the study, spinal cord tissue samples taken from rats were subjected to routine histopathological procedures and evaluated under a light microscope. Results: In the experimental group, a decrease in the number of neurons in the medulla spinalis and an increase in the number of astrocytes were noted. TUNEL staining showed that apoptosis occurred intensively in glial cells, but did not occur in anterior and posterior horn motor neurons. Conclusion: The findings showed that long-term mussel consumption can cause axonal damage in motor and sensory neurons and degeneration in glial cells. For this reason, it is important for health that marine diets in coastal areas are made with healthy and hygienic products.
