Objective(s): 5-FU, an anticarcinogenic agent, is reported to have side-effects that include hepatotoxicity and nephrotoxicity. The study objective was to investigate the protective effects of naringin on 5-FU-induced hepatotoxicity and nephrotoxicity.Materials and Methods: Thirty rodents were assigned to three groups. The control group received 1 ml of intragastric distilled water for 14 days. The 5-FU group received 1 ml of distilled water for 14 days as a placebo. On day 9, this same group received a 20 mg/kg dose of 5-FU administered intraperitoneally(IP) for a further five days. The naringin+5-FU group received a 100 mg/kg dose of naringin (IP) for 14 days. On day 9, 20 mg/kg of 5-FU was administered (IP) to this group for a further five days. On day 15, the rats were decapitated, and blood and renal and hepatic tissues were taken.Results: It was determined that serum creatinine, BUN, AST, ALT, ALP, and LDH levels, as well as cytokine levels in the liver and kidney tissues were significantly elevated in the 5-FU group, compared to the control group. The comparative values were similar in the control and naringin+5-FU groups. When the liver tissue was examined histopathologically, in the control group it was found to be normal in structure. However, necrosis was observed in the hepatocytes of the pericentric region in the 5-FU group. 8-OHdG cell density was significantly elevated in the 5-FU group, compared to the control and naringin+5-FU groups.Conclusion: Naringin was observed to have a protective effect on 5-FU-induced liver and kidney damage.

The protective effect of propolis on rat ovary against ischemia-reperfusion injury: Immunohistochemical, biochemical and histopathological evaluations.

Allergic rhinitis is an immunoglobulin-E (Ig-E)-mediated response driven by type 2 helper T cells. Hesperidin and thymol are biological agents that possess antioxidant and anti-inflammatory characteristics. The purpose of this study was to investigate the effects of hesperidin and thymol in rats with ovalbumin-induced allergic rhinitis. Thirty adult Sprague–Dawley rats were randomly assigned into five groups, each containing six animals. The first group constituted the negative control group, while the remaining groups were exposed to an ovalbumin-induced model of allergic rhinitis. In the provocation stage, 4 mL/kg saline was administered to the positive control group, 10 mg/kg desloratadine to the reference group, 100 mg/kg hesperidin to the hesperidin group, and 20 mg/kg thymol to the thymol group, all by gastric lavage for 7 days. Nasal symptoms were scored on day 22. Rats were then sacrificed, and intracardiac blood specimens were collected to measure plasma total Ig-E, IL-5, IL-13, total antioxidant capacity (TAC), and total oxidant status (TOS) levels. Nasal tissues were extracted for histopathological and immunochemical examination. Nasal symptom scores were highest in the positive control group, while hesperidin and thymol ameliorated these symptoms to the same extent as desloratadine. Ig-E, IL-5, IL-13, and TOS levels increased, while TAC levels decreased significantly in the allergic rhinitis group compared to the other groups. Significant improvement in these parameters was observed in both the hesperidin and thymol groups. At histopathological and immunohistochemical examination of the nasal cavity, severe allergic inflammation and severe TNF-α expression was determined in rats from the allergic rhinitis group. Mild inflammatory changes and mild TNF-α expression were observed in all three treatment groups. Both hesperidin and thymol were effective in suppressing allergic symptoms and inflammation in the treatment of allergic rhinitis.

The amendatory effect of hesperidin and thymol in allergic rhinitis: an ovalbumin-induced rat model

Living organisms have an innate ability to regulate the synthesis of inorganic materials, such as bones and teeth in humans. Cadmium sulfide (CdS) can be utilized as a quantum dot that functions as a unique light-emitting semiconductor nanocrystal. The increased use in CdS has led to an increased inhalation and ingestion rate of CdS by humans which requires a broader appreciation for the acute and chronic toxicity of CdS. We investigated the toxic effects of CdS on cerebellar cell cultures and rat brain. We employed a ‘green synthesis’ biosynthesis process to obtain biocompatible material that can be used in living organisms, such as Viridibacillus arenosi K64. Nanocrystal formation was initiated by adding CdCl2 (1 mM) to the cell cultures. Our in vitro results established that increased concentrations of CdS (0.1 μg/mL) lead to decreased cell viability as assessed using 3-[4,5-dimethylthiazole-2-yl]-2,5-diphenyltetrazolium bromide (MTT), total antioxidant capacity (TAC), and total oxidant status (TOS). The in vivo studies showed that exposure to CdS (1 mg/kg) glial fibrillary acidic protein (GFAP) and 8-hydroxy-2' -deoxyguanosine (8-OHdG) were increased. Collectively, we describe a model system that addresses the process from the synthesis to the neurotoxicity assessment for CdS both in vitro and in vivo. These data will be beneficial in establishing a more comprehensive pathway for the understanding of quantum dot-induced neurotoxicity.
