Background: Alcoholic liver disease (ALD) is a worldwide health problem.Ozone and melatonin are agents that are widely used for their antioxidant properties in medical therapies.In this study, we aimed to evaluate the use of ozone and melatoninin ALD.Materials and Methods: Forty-eight rats were used and ethanol, melatonin, and ozone were administrated. Histopathological evaluation was performed and activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma glutamyl transferase (GGT) total antioxidant status (TAS), total oxidant status (TOS), and malondialdehyde (MDA)were determined in the blood samples, while TAS, TOS, and MDA parameters were measured in the liver tissue samples.Results: There were statistically significant differences between the studied groups concerning ALT, AST activities and TAS, TOS, and MDA levels. Vascular congestion, hepatocyte damage, periportal inflammation, and microvesicular steatosis were detected inthe alcohol-induced toxicity group.Conclusions: In the light of histopathological findings, we can claim that melatonin and ozone administrations are beneficial for alcohol-induced hepatotoxicity. However, ozone application is superior to melatonin.

SUMMARY INTRODUCTION Liver biopsies such as tru-cut (sharp needle) and fine-needle aspiration cytology (FNAC) are the most commonly preferred techniques to detect the grade and stage of certain liver diseases. In this study, we aimed to compare the efficiency of USG-guided tru-cut biopsy and fine-needle aspiration cytology in an experimental alcoholic liver disease model. METHODS Thirty-six female Wistar albino rats, 4-6 months old, and weighing from 190 to 250 g, were used in this study. The animals were randomly divided into six equal groups: G1 (control), G2 (tru-cut control), G3 (FNAC control), G4 (Alcoholic liver disease model), G5 (Alcoholic liver disease model + FNAC), and G6 (Alcoholic liver disease model + tru-cut biopsy). After a histopathological evaluation by light microscopy, the sensitivity, specificity, positive and negative predictive values of FNAC and tru-cut biopsy for the diagnosis of liver lesions were calculated. RESULTS No pathology was detected in G1 except for mild congestion. On the other hand, hepatocyte damage, periportal inflammation, congestion, and fatty changes were detected in all liver tissues of the alcoholic liver disease groups. The sensitivity of hepatocyte damage, inflammation, congestion, and fatty change parameters for FNAC were 33.3%, 80%, 0%, and 0%, respectively, while the sensitivity of the same variables for tru-cut were 66.7%, 40%, 100%, and 20%, respectively. DISCUSSION Both techniques were superior in some aspects. FNAC can be an attractive alternative to tru-cutbiopsy and applied in routine practice in the diagnosis of non-tumoral liver diseases.

The purpose of this investigation was to identify the presence of parasite infections and cystic formation in Scomber japonicus, Scomber scombrus, and Thunnus thynnus. Euryphorus brachypterus and Clavellisa scombri were identified from Thunnus thynnus and Scomber scombrus, respectively. Anisakis pegreffii was identified from Scomber japonicus and Scomber scombrus by using molecular methods. Additionally, Anisakis typical was determined from Scomber japonicus.
