Effects of benzophenone-3 on the liver and thyroid of adult zebrafish.
1. Benzophenone-3 (BP-3), commonly known as oxybenzone, is an organic compound that acts as a sunscreen, protecting the skin from UVA and UVB rays. Thus, the objective of this study was to investigate the effects of BP-3 on the liver and thyroid using morphological and biochemical approaches.2. Adult male zebrafish were randomly assigned to three groups, each with three repetitions (n = 10 per group): water control, solvent control (0.01% ethanol), and 1 μg/L of BP-3, using a static exposure system for 96 hours. After the experiment, histopathological analyses of the liver and thyroid were performed, along with histochemical analyses (glycogen) and biochemical evaluations of the antioxidant enzymes Superoxide Dismutase (SOD) and Catalase (CAT).3. Exposure to BP-3 resulted in significant histopathological changes in the liver of Danio rerio, increasing the frequency of circulatory disturbances, progressive changes, inflammatory responses, and regressive changes. On the other hand, the thyroid gland did not show any morphological changes during exposure to BP-3, maintaining its typical structure with follicles. There was a significant increase in SOD activity, while CAT showed no changes after 96 hours of exposure.4. The results obtained demonstrate that exposure to BP-3 causes significant morphophysiological changes in the liver of D. rerio, highlighting not only the negative impacts on the health of these organisms but also the ecotoxicological potential of the substance and its consequences for aquatic biota in contaminated environments.
期刊介绍:
Xenobiotica covers seven main areas, including:General Xenobiochemistry, including in vitro studies concerned with the metabolism, disposition and excretion of drugs, and other xenobiotics, as well as the structure, function and regulation of associated enzymesClinical Pharmacokinetics and Metabolism, covering the pharmacokinetics and absorption, distribution, metabolism and excretion of drugs and other xenobiotics in manAnimal Pharmacokinetics and Metabolism, covering the pharmacokinetics, and absorption, distribution, metabolism and excretion of drugs and other xenobiotics in animalsPharmacogenetics, defined as the identification and functional characterisation of polymorphic genes that encode xenobiotic metabolising enzymes and transporters that may result in altered enzymatic, cellular and clinical responses to xenobioticsMolecular Toxicology, concerning the mechanisms of toxicity and the study of toxicology of xenobiotics at the molecular levelXenobiotic Transporters, concerned with all aspects of the carrier proteins involved in the movement of xenobiotics into and out of cells, and their impact on pharmacokinetic behaviour in animals and manTopics in Xenobiochemistry, in the form of reviews and commentaries are primarily intended to be a critical analysis of the issue, wherein the author offers opinions on the relevance of data or of a particular experimental approach or methodology
