Özet

Ethyl carbamate (EC, urethane). which is used as an anesthetic especially by veterinarians due to its very long duration of action, is also a naturally occurring compound in all fermented foods and beverages. Although the health problem of EC is related to its carcinogenic potential, the scarcity of current studies that can be used in the evaluation of usage limits encouraged us to do this study. In this context, zebra fish embryos were exposed to serial doses of EC. According to the results, it was observed that CC exposure caused a significant decrease in survival and hatching rates as well as significant body malformations. Whole-mount staining results showed that CC caused dose-dependent increased apoptosis. Oxidative stress caused by EC exposure was demonstrated by whole-mount staining, transcriptional and immunohistochemically. Furthermore, it has been shown histochemically that CC exposure causes necrosis and degeneration in the brain. In behavioral tests, it was observed that CC caused hyperactivity associated with these neuronal degenerations. In addition, a dramatic decrease in blood flow was detected in association with pericardial edema. In the light of the current results, it should be carefully considered that EC can be found naturally in many human diets, especially fermented foods. (C) 2021 Elsevier B.V. All rights reserved.
