Background/aims: Sepsis is one of the major problems encountered in intensive care units, causing organ damage and increasing mortality. Suberosin (SBR) is a type of coumarin with antioxidant and anti-inflammatory activities. The goal of this study is to explore the protective effects of SBR on the lungs in a rat model of sepsis. Methods: Male Wistar rats were utilized in this study. A cecal ligation and puncture (CLP) model was applied to induce sepsis. Rats were separated into six groups with nine animals in each group, including healthy control, SBR, CLP, and CLP + SBR (5, 10, and 20 mg/kg) groups. Superoxide dismutase (SOD), glutathione (GSH) enzyme activities, and malondialdehyde (MDA) level were measured via enzyme-linked immunosorbent assay (ELISA). The messenger RNA (mRNA) expressions of tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β) were evaluated by real-time polymerase chain reaction (RT-PCR). Histopathological changes in the lungs were investigated with hematoxylin and eosin (H&E). Results: MDA levels and GSH and SOD enzyme activities were negatively affected in the CLP group, but SBR treatment ameliorated these oxidative stress parameters in the SBR1-3 groups (p< 0.05). The mRNA expressions of TNF-α and IL-1β were increased in the CLP group, and SBR treatment decreased those expression levels in a dose-dependent manner (p < 0.05). Organ damage and necrosis were seen in the CLP group and were alleviated in the SBR3 group. Immunohistochemical (IHC) analysis of lung tissues demonstrated decreased TNF-α and IL-1β immunopositivity in the SBR1-3 groups (p< 0.05). Conclusions: SBR ameliorated sepsis-related lung injury in a dose-dependent manner. This compound has significant potential as a future agent in the treatment of sepsis.

Background: Increased oxidants and proinflammatory cytokines play a role in the pathogenesis of ovarian ischemia-reperfusion (OIR) injury and related infertility. Carvacrol has antioxidant, antibacterial and anti-inflammatory properties. Methods: Protective effect of carvacrol against ischemia-reperfusion (IR)-related ovarian damage and infertility was investigated. IR process were applied to the ovaries of rats, which were divided into the following groups (n = 12): OIR, IR +50 mg/kg carvacrol (IRC-50), IR +100 mg/kg carvacrol (IRC-100) and sham group (SG). After the reperfusion process, six rats from each group were killed and the removed ovaries were examined biochemically and histopathologically. The remaining animals were kept two months with mature male rats to reproduce. Results: At a dose of 50 mg/kg, carvacrol suppressed the oxidant parameter increase and antioxidant decrease caused by IR in ovarian tissue. At a dose of 100 mg/kg, carvacrol antagonized both oxidant and proinflammatory cytokine increase and antioxidant decrease. Histopathologically, severe degeneration of follicles in the ovaries of the OIR group, necrotic cell accumulations, hemorrhage in the corpus luteum, edema in the interstitial tissue, polymorphous nuclear leukocyte (PNL) infiltration, and congestion and dilation of blood vessels were detected. Inflammatory symptoms such as edema in the ovarian tissue, congested dilated blood vessels and PNL infiltration were observed at a dose of 50 mg/kg of carvacrol, but these histopathological findings were not observed at a dose of 100 mg/kg. Conclusion: A dose of 100 mg/kg carvacrol, which eliminated inflammatory damage, significantly prevented the development of IR-induced infertility. Carvacrol may be beneficial in the treatment of IR-related ovarian damage and infertility. Copyright:

Altındağ, Fikret; Boğokşayan, Seda; Bayram, Sinan
This study aims to evaluate in vivo protective effects of eumelanin (EU) on diethylnitrosamine (DEN)-induced liver injury. Wistar albino male rats were divided into 6 groups (n = 6), Control, DMSO, DEN, DEN + EU10, DEN + EU15, and DEN + EU20. Animals in the DEN group were injected i.p a single dose of 200 mg/kg DEN, DEN + EU10 group was given 10 mg/kg EU, DEN + EU15 group was given 15 mg/kg, DEN + EU20 group was given 20 mg/kg EU for a week. The results showed that there was no significant difference in vessel volume density between the groups. Inflammatory cell infiltration, hydropic degeneration, and necrotic cells were observed in the DEN group, and these histopathological changes were significantly reduced in all treatment groups. Although there was a low intensity of PAS-positive staining in the DEN groups, moderate staining was observed in the treatment groups. While Caspase-3, PCNA, TNF-α, and IL-6 expressions increased in the DEN group, their expressions decreased in the EU-treated groups. DEN increased AST, ALT, and MDA levels and decreased CAT levels. In particular, the EU10 dose significantly improved these parameters. The present study revealed that eumelanin has protective effects against DEN-induced liver injury.

Üçel, Umut İrfan; Can, Özgür Devrim; Demir Özkay, Ümide; Ulupinar, Emel
In this study, we investigated the potential therapeutic effects of tofisopam, a 2,3-benzodiazepine derivative anxiolytic, on cognitive deficits in rats with scopolamine-induced amnesia. Cognitive performance of the rats was investigated by using the Morris water maze and passive avoidance tests. Changes in motor activity were assessed by using the activity cage and Rota-rod tests and then morphological changes in the hippocampus were assessed via immunohistochemical stainings. The results indicated that scopolamine impaired learning and memory parameters in rats. Worsened cognitive performance, neuronal loss, and decreased hippocampal synaptophysin, Ki-67, and glial fibrillary acidic protein density were observed. Tofisopam administration at a dose of 50 mg/kg for seven days improved the impaired cognitive performance, enhanced the attenuated synaptic transmission in the hippocampus, increased proliferation in subgranular zones, and improved the decrease in astrocytes in amnesic rats. These findings point out the anti-amnesic effects of tofisopam with concomitant improvements in the hippocampal synaptogenesis, neurogenesis, and glial plasticity, for the first time. Presented beneficial effects of tofisopam on cognitive dysfunctions may have a notable clinical value considering the fact that one of the most important side effects of 1,4-benzodiazepines, which are classical anxiolytic drugs, is amnesia. However, these preclinical results need to be confirmed with further clinical studies, first.
