    Investigation of the protective effects of geraniol on cyclophosphamide-induced hepatotoxicity in rats
    (Natl Inst Science Communication-Niscair, 2025) Canbaz, Halime Tuba; Kalkan, Serpil; Kocabas, Rahim; Sozen, Mehmet Enes; Cuce, Gokhan
    This study aimed to investigate the efficacy of geraniol (Ge) on improving cyclophosphamide (CP)-induced hepatotoxicity in rats. A total of 42 rats in 6 groups, group I (control); group II (CP at 20 mg/kg); group III (CP at 20 mg/kg + Ge at 100 mg/kg); group IV (CP at 20 mg/kg + Ge at 200 mg/kg); group V (Ge at 100 mg/kg); and group VI (Ge at 200 mg/kg), were used. Ge was administered orally via gavage daily for 14 days. Intraperitoneal CP was administered from day 8 to 14. Blood serums were analysed for alanine aminotransferase (ALT), aspartate aminotransferase (AST), total antioxidant status (TAS), and total oxidant status (TOS) over a 14-day period. Liver sections were stained using hematoxylin and eosin (H&E). NF kappa B expression was assessed using immunohistochemistry. Bax-Bcl immunofluorescence was employed to identify apoptosis, whereas TUNEL was utilised to detect DNA fragmentation. Group III and group IV exhibited significantly decreased histopathological scores, NF kappa B expression, and DNA breaks compared to group II. The OSI and AST levels were significantly reduced in group IV compared to group II. The current investigation indicates that Ge possesses anti-inflammatory and antioxidant effects on CP-induced liver damage.

    Objective(s): Deltamethrin (DLM) is a widely used insecticide in agriculture; however, exposure to it can lead to serious health problems. This study aimed to evaluate the protective effects of hesperidin (HSP), a natural antioxidant, against DLM-induced liver toxicity. Materials and Methods: Thirty-two male Wistar Albino rats (250-300 g, 4 months old) were divided into four groups. The control group received 1 ml of corn oil via oral gavage for 30 days. The DLM group received 1.28 mg/kg DLM in corn oil for 30 days. The DLM+HSP 100 mg/kg and DLM+HSP 300 mg/kg groups received 1.28 mg/kg DLM followed by 100 mg/kg or 300 mg/kg HSP in distilled water, respectively, 30 min after DLM administration for 30 days. Liver tissues were examined histopathologically. Masson's trichrome staining and PCR assessed fibrosis. Caspase 3 and 9 expressions in liver tissues were determined by immunohistochemistry and PCR. Biochemical analyses were conducted on serum samples. Results: HSP supplementation led to a dose-dependent decrease in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. DLM exposure decreased antioxidant capacity, while HSP supplementation increased it dose-dependently. Histopathological evaluations showed increased liver damage in the DLM group, while HSP administration reduced liver toxicity. Masson's trichrome staining and analysis of collagen I (COL1A1) and collagen III (COL3A1) gene expression revealed increased fibrosis in the DLM group, which was attenuated with HSP treatment. Conclusion: The potential prevention of DLM-induced liver toxicity and apoptosis by HSP may be an alternative protective strategy.
