In this study, the protective effect of melatonin was investigated in lipopolysaccharide induced sepsis model. Twenty‐eight rats were randomly divided: Control, Melatonin, LPS and LPS + Melatonin. After LPS application, surgically remove kidney and liver tissues. The level of malondialdehyde (MDA) an oxidative stress marker and the immunoreactivity of Toll‐like receptor‐4 (TLR4), tumor necrosis factor‐α (TNF‐α), and transcription factor NF‐κB were evaluated immunohistochemically. Expression levels for TLR4, TNF‐α, NF‐kB, IL‐1β (interleukin 1 beta), and IL‐6 (interleukin 6) were evaluated. Additionally, Argyrophilic NOR staining was performed in tissues. Vacuolization and inflammation were more intense in the kidney and liver sections in the LPS group compared to the other groups. It was observed that vacuolization and inflammation were decreased in LPS + Melatonin applied groups. It was determined that glomerular damage was increased in the LPS and LPS‐melatonin groups, but the damage rate LPS‐Melatonin group was decrease in the LPS group. It was determined that the MDA level in tissues of the LPS group was importantly increased compared to other groups. Additionally, TAA/NA ratio statistically significant differences were discovered between the groups. This study supports the potential protective effects of 10 mg/kg melatonin by modulating critical markers of local immune reaction in a model of LPS‐induced sepsis.

The development and progression of sepsis are multifactorial and influence the immunological, endocrine, and cardiovascular systems of the body. Our knowledge of the key mechanisms involved in the pathogenesis of sepsis has expanded exponentially, yet this still needs to be translated into effective targeted therapeutic regimes. In the present study, we aimed to determine whether resveratrol has positive effects in the experimental sepsis rat model. Twenty‐eight male Spraque–Dawley rats were randomly divided into four groups (n = 7) as follows: control, lipopolysaccharide (LPS) (30 mg/kg dose), resveratrol, and LPS and resveratrol. After the experiment, liver and kidney tissues were collected for histopathological evaluation, blood serums were collected to measure malondialdehyde levels with enyzme‐linked immunosorbent assay, and Toll‐like receptor‐4 (TLR4), tumor necrosis factor‐α (TNF‐α), nuclear factor‐κB (NF‐κB) immunoreactivity density was evaluated immunohistochemically. In addition, messenger RNA expression levels for TLR4, TNF‐α, NF‐κB, interleukin‐1β, and interleukin 6 were measured. In addition, the damage observed in liver and kidney tissue was determined by AgNOR (argyrophilic nucleolar organizer regions) staining. LPS application caused severe tissue damage, oxidative stress, and increased the expressions of proinflammatory proteins and genes we evaluated, while resveratrol application eliminated these negativities. Resveratrol has been proven to suppress the TLR4/NF‐κB/TNF‐α pathway, a possible therapeutic signaling pathway that is important in initiating the inflammatory response in an animal model of sepsis.

Introduction One of the most important health problems today is cancer. The aim of this study was to investigate the in vitro effect of yarrow (Y) with known anticarcinogenic effect on Ehrlich ascites tumor (EAT). Materials and Methods The above-ground part (300 g) of Y was macerated with water and extracted three times for 24 hours at 37°C in a shaking water bath. In the study, EAT cells were divided into control, DMSO group 5-FU, 50, 100, 200, 400 and 800 μg/ml YP groups. Results At the end of the hour, it was observed that total apoptosis increased significantly in Y groups (especially 50 μg/ml) compared to the control group (p<0.05). It was observed that Y slowed the division of EAT cells (especially 800 μg/ml) by stopping the cell cycle at the G0/G1 stage. It was concluded that Y (especially at high doses) triggered apoptosis by significantly increasing the percentage of total depolarized cells (p<0.001) in all three time periods. Conclusions The results obtained showed that Y extract may have an antitumoral effect on EAT cells. It is thought that this study will contribute to studies on cancer treatment.

Introduction Mistletoe has been used alone or as a complementary therapy in the treatment of different diseases for years. In this study, the antitumoral effect of mistletoe fruit extract on Ehrlich ascites tumor (EAT) cells was evaluated. Materials and Methods EAT cells from preformed stock mice were transferred to culture dishes containing 5-fluorouracil (5-FU) and mistletoe extracts at different doses (100, 200, 400, and 800 μg/ml). These cells were incubated at 37 °C in an environment with 95% humidity and 5% CO2. At the end of the incubations, the apoptosis status of the cells, cell cycle, mitochondrial membrane potential, and proliferation status with the argyrophilic (Ag) nucleolar organizer region staining (NORs) method were evaluated. Results As a result, it was observed that the mistletoe fruit extract and 5-FU induce apoptosis of EAT cells. It was concluded that the 5-FU substance arrests the cell cycle at the G0/G1 stage, while the mistletoe arrests the cell cycle at the S and G2/M stages. The depolarization rate of the mistletoe treated cells was higher. As a result of the evaluation made with the AgNORs method, it was seen that mistletoe and 5-FU could be effective in reducing the proliferation of EAT cells. Conclusions It was seen that mistletoe fruit extract could be effective in stimulating the apoptosis and depolarization of cancer cells. The results of other studies in the literature and our study support each other. It was concluded that the mistletoe plant may be useful in cancer treatment.

Aim: Vestibular neuritis is one of the most common causes of acute spontaneous vertigo. In our study, we aimed to analyze the cerebellum volume and cerebellum connections in patients diagnosed with vestibular neuritis using the VolBrain program. Materials and Methods: 10 patients and 9 healthy (control) persons were included in the study. Automatic segmentation and volumetric analysis of cerebellum and cerebellum lobules were investigated using magnetic resonance images (MRI) of 19 people. Results: The volumes of 10 cerebellar regions were measured and compared between the patient and control groups. The total volume of the cerebellum was calculated as 123.82 ± 2.57 cm3 in the control group and 119.97 ± 4.15 cm3 in the patient group. In addition, the average amount of gray matter in the cerebellum was 90.63 ± 6.59 cm3 in the control group and 87.87 ± 16.12 cm3 in the patient group. We found volumetric changes to be statistically significant. Conclusion: By performing cerebellum segmentation with 3D T1 sequence of MRI images taken from patients diagnosed with vestibular neuritis, volume measurement and more detailed examinations can be performed easily with the help of the volBrain program. Moreover, its low cost and its usefulness in diagnosis suggest that this method will be beneficial.
