Abstract
In this study, our aim was to investigate the effects of restorative materials such as composite, compomer and high viscosity glass ionomer, which are frequently used in dentistry, on L929 fibroblast cells by evaluating the oxidative stress parameters, pro- and anti-inflammatory cytokines, and apoptosis markers. L929 fibroblast cells were cultured, and dental filling materials were applied in two doses (50 and 100 µl). Immunohistochemical staining was performed for experimental groups with Anti-Bax and Anti-Caspase 9 antibodies. Then, ELISA technique was used to detect the level of TNF-alpha, TGF-beta, IL-1-beta, IL-6, IL-10, LPO and CAT. In the light of the data, the examined dental filling materials were effective on increasing the TGF-beta, IL-10, LPO and CAT levels, and decreasing the TNF-alpha, IL-1-beta, and IL-6 levels. The histological micrographs were also support the issues. When the levels of H-score in Caspase 9 labeled micrographs were evaluated, the mean of the control group was lower than the mean of the experimental groups. Biocompatibility varies according to the content of the material, the amount of residual monomer, and its solubility. Although all the experimental groups have cytotoxic effects, the least effect is seen in the Omnichroma group.

Abstract
In this study, the main hypothesis is that paeoniflorin may inhibit some cellular processes such as oxidative stress and inflammation. For this reason, we aimed to investigate the potential protective effects of a natural compound, paeoniflorin, on rat model of ovarian ischemia-reperfusion injury by detecting the oxidative stress parameters and inflammatory process parameters. 42 female Wistar-albino rats were divided into 6 random groups. The rats were subjected to 3-hour ischemia and 3-hour reperfusion process. Then, paeoniflorin at doses of 25, 50 and 100 mg/kg were applied 30 min before the reperfusion. The levels of pro-inflammatory (IL-1-β, IL-6, TNF-α) and anti-inflammatory (IL-10, TGF-β) cytokines were measured by ELISA. Similarly, IL-6, IL-10, TNF-α, NF-κB p65) positivity rates were detected by immunohistochemical staining. Additionally, oxidative stress parameters (MDA, GSH, SOD) were measured by tissue biochemistry. Ischemia-reperfusion injury caused significant increase in the levels of SOD, MDA, TNF-α, IL-1-β, IL-6 and NF-κB p65, while paeoniflorin treatments improved the related parameters in a dose-dependent manner. As a conclusion, our findings support the evidence that paeoniflorin has a potential protective effects on ovarian ischemia-reperfusion injury. Further detailed studies should be performed to shed light the molecular mechanism of these protective effects.

Abstract
INTRODUCTION In this study, our aim was to investigate the possible protective and therapeutic effects of these two flavonoids, baicalein, and naringin, in 50 and 100 mg/kg doses applied both before and after cecal ligation and puncture (CLP) procedures in a polymicrobial sepsis rat model, and evaluate the possible contribution of oxidative and inflammatory markers by immunological, biochemical, molecular, and histopathological methods. METHODS Sixty-six Wistar albino rats were divided into 11 groups. The pro-inflammatory (TNF-alpha, IL-1-beta, and IL-6) and anti-inflammatory (TGF-beta and IL-10) cytokine levels were measured by ELISA technique. CD3, CD68, and nuclear factor kappa B positivity rates were detected by immunohistochemical methods. Oxidative stress parameters (MDA, SOD, and GSH) were measured by tissue biochemistry. RESULTS Sepsis caused a significant increase in all pro-inflammatory cytokine levels and MDA activity. Also, it led to an increase in the positivities of CD3, CD68, and NF-κB markers. However, especially pre-CLP doses of baicalein and naringin inhibited the inflammation process by suppressing pro-inflammatory and increasing anti-inflammatory cytokine levels, as well as regulating the oxidative stress process by normalizing the oxidant/anti-oxidant enzyme levels. CONCLUSION Both pre- and post-application of baicalein and naringin are quite effective to prevent sepsis-caused cellular processes. This protective and therapeutic effects by baicalein and naringin in animals with sepsis seems to be originated from the high antioxidant capacity and inhibition of pro-inflammatory cytokine production. Thus, those natural agents may prove to be valuable protective agent against septic shock.

Abstract
In this study, our aim was to show both the single and combined effects of cisplatin and jaceosidin in SHSY-5Y neuroblastoma cells. For this purpose, we used MTT cellular viability assay, Enzyme-Linked Immunosorbent Assay (ELISA), Transmission Electron Microscopy (TEM), Immunofluorescence Staining Assay (IFA) and Western blotting (WB) assay. According to MTT findings, IC50 dose was detected as 50 µM cisplatin and 160 µM jaceosidin co-application. Therefore, experimental groups were finally selected as control, cisplatin, 160 µM jaceosidin and Cisplatin +160 µM jaceosidin. Cell viability was decreased in all groups, and the IFA findings confirmed the viability analysis. WB data indicated that matrix metalloproteinase 2 and 9 levels, as indicators of metastasis, decreased. While LPO and CAT levels increased in all treatment groups, it was observed that the activity of SOD decreased. When TEM micrographs were investigated, cellular damages were determined. In the light of these results, it can be said that cisplatin and jaceosidin have a potential to increase the effects of each other synergistically.

Abstract
Aim: The objective of this study was to evaluate the possible protective effects of probiotic bacteria, especially Bifidobacterium and Lactobacillus strains, on 4,4'-dichlorodiphenyltrichloroethane (DDT)-induced toxicity. For this reason, we evaluated the relationship between probiotics and toxicity by checking immunological and immunohistochemical parameters. Materials & methods: Probiotic pretreatment was applied to 36 Wistar albino rats for 12 consecutive days. Serum aspartate aminotransferase and alanine aminotransferase levels were detected. CD3 and NF-κB staining methods were then performed by immunohistochemistry. Finally, pro- and anti-inflammatory cytokines were measured by ELISA. Results: DDT caused a serious increase/decrease in some cytokine parameters. The effective dose was 1 × 1011 colony-forming unit probiotic treatment. CD3 and NF-κB positivity were intense in DDT group whereas the intensity was reduced in probiotic treatment groups. Discussion: The probiotic mixture has a potential to prevent inflammatory and oxidative stress related organ injuries. Further studies should be performed to explain the possible mechanisms.

Abstract
Objective The purpose of this study was to compare the use of an intravitreal injection of infliximab and of dexamethasone combined with vancomycin to treat experimental endophthalmitis induced by Staphylococcus epidermidis. Materials and Methods The study was conducted between March 25 and April 13, 2012. Twenty-five six-month-old healthy rabbits were used, each weighing 2.5-3 kg. The rabbits were randomized into five groups with five animals per group. Endophthalmitis was induced by 0.1 mL (103 colony-forming units) S. epidermidis in all groups. In group 1, injection was not implemented after the occurrence of endophthalmitis. In groups 2, 3, and 4, the following intravitreal injections were given 24 h after the occurrence of endophthalmitis: group 2, 0.1 mg/0.1 mL vancomycin; group 3, 1 mg/0.1 mL vancomycin and 1 mg/0.1 mL dexamethasone; and group 4, 1 mg/0.1 mL vancomycin and 2 mg/0.1 mL infliximab. Group 5 was the control/uninfected group. The rabbits were clinically assessed each day for seven days. On day 9, a histopathologic evaluation was performed after enucleation. Results After a clinical evaluation, no statistically significant difference was found between the vancomycin+infliximab and vancomycin+dexamethasone groups (p>0.05). The difference was significant when both groups were compared with the vancomycin group (p<0.001). After the histopathologic evaluation, no statistically significant difference was found among the three groups (p>0.05). Conclusion An intravitreal injection of infliximab and of dexamethasone combined with vancomycin have similar clinical and histopathologic effects. To supplement the antibiotic treatment of endophthalmitis, infliximab in a safe dose range can be used as an alternative to dexamethasone to suppress inflammation and prevent ocular damage.

Abstract
OBJECTIVE We hypothesize that apigenin may inhibit some cellular process of sepsis-induced spleen injury and simultaneously improve inflammation and oxidative stress. Therefore, the aim of this study was to investigate the potential protective effects of apigenin in a polymicrobial sepsis rat model of by cecal ligation and puncture. MATERIALS AND METHODS 64 female Wistar albino rats were divided into 8 groups. The pro-inflammatory (tumor necrosis factor-alpha, interleukin-6, and interleukin-1-beta) and anti-inflammatory (tumor growth factor-beta and interleukin-10) cytokine levels were measured by enzyme-linked immunosorbent assay. CD3, CD68, and nuclear factor kappa B (NF-κB) positivity rates were detected by immunohistochemical methods. Oxidative stress parameters were measured by tissue biochemistry. RESULTS Sepsis caused a significant increase in TNF-alpha, IL-1-beta, IL-6, and TGF-beta levels whereas it reduced IL-10 level. Additionally, it led to an increase in CD3, CD68, and NF-κB positivity rates as well as oxidative stress parameters levels. However, apigenin inhibited the inflammation process, increased the IL-10 level and normalized the oxidative stress parameters. DISCUSSION AND CONCLUSION Pretreatment with apigenin results in a significant reduction in the amount of inflammatory cells. The beneficial effect of apigenin on spleen injury also involved inhibition of NF-κB pathway, suppression of proinflammatory cytokines, and induction of anti-inflammatory cytokine production. Additionally, it led to a decrease in oxidative stress in spleen tissue. Taking everything into account, apigenin may be an alternative therapeutic option for prevention of sepsis-induced organ.

Abstract
OBJECTIVES In the present study, our aim was to investigate the possible protective effects of epigallocatechin gallate (EGCG) on lipopolysaccharide (LPS)-induced hepatotoxicity by using Hep3B human hepatoma cells. Specifically, the study examines the role of some proinflammatory markers and oxidative damage as possible mechanisms of LPS-associated cytotoxicity. Consequently, the hepatocellular carcinoma cell line Hep3B was chosen as a model for investigation of LPS toxicity and the effect of EGCG on LPS-exposed cells. MATERIALS AND METHODS The Hep3B human hepatoma cells were used for this study. The cytotoxic effects of chemicals (EGCG and LPS), AST and ALT levels, SOD and CAT activities, GSH-Px level and TNF-alpha and IL-6 levels were detected by using different biochemical and molecular methods. LPS and EGCG were applied to cells at various times and doses. RESULTS The highest treatment dose of EGCG (400 µM) led to a dramatic decrease in SOD level and increase in CAT and GSH levels. Additionally, the highest dose of EGCG also led to a dramatic increase in TNF-alpha and IL-6 levels. On the other hand, effective doses of EGCG (200 and 100 µM) normalized all related parameters levels. CONCLUSION LPS caused hepatotoxicity, but interestingly, a high dose of EGCG was found to be a cytotoxic agent in this study. However, other two doses of EGCG led to a decrease in both inflammatory cytokine levels and antioxidant enzyme levels. Further studies should examine the effect of EGCG on secondary cellular signaling pathways.

Abstract
BACKGROUND Hepatitis B virus infection is one of the major world health problems. Epigallocatechin-3 gallate is the major component of the polyphenolic fraction of green tea and it has an anti-viral, anti-mutagenic, anti- tumorigenic, anti-angiogenic, anti-proliferative, and/or pro-apoptotic effects on mammalian cells. In this study, our aim was to investigate the inhibition of HBV replication by epigallocatechin-3 gallate in the Hep3B2.1-7 hepatocellular carcinoma cell line. MATERIALS AND METHODS HBV-replicating Hep3B2.1-7 cells were used to investigate the preventive effects of epigallocatechin-3 gallate on HBV DNA replication. The expression levels of HBsAg and HBeAg were determined using ELISA. Quantitative real-time-PCR was applied for the determination of the expression level of HBV DNA. RESULTS Cytotoxicity of epigallocathechin-3-gallate was not observed in the hepatic carcinoma cell line when the dose was lower than 100 μM. The ELISA method demonstrated that epigallocatechin-3 gallate have strong effects on HBsAg and HBeAg levels. Also it was detected by real-time PCR that epigallocatechin-3 gallate could prevent HBV DNA replication. CONCLUSIONS The obtained data pointed out that although the exact mechanism of HBV DNA replication and related diseases remains unclear, epigallocatechin-3 gallate has a potential as an effective anti-HBV agent with low toxicity.

Abstract
Helicobacter pylori infection is usually acquired in early childhood and it can persist throughout life without antibiotic treatment. This study aimed to compare the accuracy of the noninvasive H. pylori Stool Antigen Test-applied on the stool samples with the invasive gold standart Rapid Urease Test-applied on the gastric biopy samples of patients with upper gastrointestinal complaints. After endoscopy, biopsy and stool specimens were taken in 122 patients. The infection was detected with rapid urease test which is accepted as gold standart test. Rapid, one-step H. pylori card test was applied to all patients stool specimens. In this study 106 of the 122 patients (86.8%) were positive for H. pylori infection, while 16 of the 122 patients (13.2%) were negative. H. pylori card test was negative in 13 of the 16 patients and was positive in 98 of the 106. The sensitivity, specifity, positive and negative predictive values were 92.45%, 81.25%, 97.02%, and 61.90%, respectively. H. pylori card test is rapid, easy, noninvasive and inexpensive methods for detection H. pylori infection. This test showed high sensitivity and specificity. Additionally, it may be a good alternative to invasive tests for the detection of H. pylori infections especially in children.

Abstract
Bortezomib (BORT) is an anti-tumour agent that inhibits proteasome, which is responsible for the degradation of many intracellular proteins. Although some side-effects and chemotherapeutic effects of BORT are known, there has not been enough research regarding its effects on different tissues of proteasome inhibition in the senile period (post-menopausal). The aim of this study was to investigate the safety of using BORT during the post-menopausal period. The post-menopausal effects of BORT were investigated on ovariectomized (OVX) Spraque-Dawley rats. The female rats were separated into three groups: control, ovariectomized (OVX), and OVX + BORT. OVX and OVX + BORT groups consisted of six rats in each. BORT was administered intraperitoneally in a dosage of 0.2 mg/kg two days a week for four weeks after OVX. The uteri of the rats were investigated using morphometrical, histopathological, and immunohistopathological methods. A striking atrophy in the endometrium and myometrium was observed due to an estrogen deficiency in the OVX group. The partial protective effect of BORT administration was observed morphometrically and histopathologically. In immunohistochemical research, cytoplasmic NF-KB activity was observed in the presence of proteasome inhibition in the endometrium. In light of these findings, the limited protective effects of post-menopausal BORT administration are worth mentioning.

Abstract
INTRODUCTION Beta-carotene is a well-known antioxidant and precursor of Vitamin A that has a preventative role in the oxidative damage process. Our aim was to investigate the possible preventive effects of beta-carotene on oxidative damage via experimental ischemia and ischemia-reperfusion models in rat ovaries. MATERIALS AND METHODS A traumatic vascular clamps were used for 3h to induce ischemia (Group 2, 3, 4, 5, 6, 7). The clamps were then removed to allow reperfusion for 3h (Group 3, 6, 7). Sham-operated rats (Group 1) underwent laparotomy without the induction of ischemia/reperfusion injury. Real-Time-PCR was performed to determine IL-1-beta, IL-6 and iNOS expression levels. Histopathological (H&E) and immunohistochemical staining (NF-kβ p65) processes were then performed. Finally, SOD, GSH, and MDA levels were determined. RESULTS Intense hemorrhagic areas were observed in both the ischemia and ischemia/reperfusion groups, whereas minimal hemorrhage was observed in the treatment groups. The ischemia and ischemia/reperfusion groups exhibited extreme immunoreactivity, detected by NF-kβ p65 staining; this reactivity decreased after the application of beta-carotene. The expression of IL-1-beta, IL-6, and iNOS in the injury groups increased significantly, whereas a dose-dependent improvement was observed in the treatment groups. Finally, MDA levels increased significantly and SOD and GSH levels decreased drastically in the injury groups. However, these values obtained from I/R groups were normalized after beta-carotene treatment. DISCUSSION In this study, we demonstrated via molecular and biochemical parameters the protective effect of beta-carotene, which is a potent antioxidant, on the experimental ischemia-reperfusion model.

Abstract
BACKGROUND Liver is one of the most important organs affected by exercise. According to the literature a few study to date has investigated the effects of estrogen supplementation on exercise-induced oxidative stress in liver tissue of rats. OBJECTIVES We aimed to investigate the effects of estrogen supplementation on oxidative stress markers in liver tissue of exercised rats. MATERIALS AND METHODS Male rats (n = 35) were divided as estrogen supplemented (n = 18) and non-supplemented groups (n = 17); these groups were further divided as rest and eccentric exercised groups. Eccentric exercise groups were further divided as rats killed after 1 hour and 48 hours of eccentric exercise. Estrogen (10 mg/kg) was administered subcutaneously for 30 days. Eccentric exercise was applied as treadmill run (15° downhill, 20 m/min) consisting of periods of "5 min" run and 2 min rest repeated 18 times. The rat liver was examined biochemically and histologically. Activities of GST, GSH-Px, CAT, SOD and MDA concentration were also measured spectrophotometrically. RESULTS Some disruptions were detected in experimental groups compared with the control group. Additionally, exercise training caused an increase in SOD and decrease in GSH-Px activities in some experimental groups. SOD activities increased significantly in group 3 (Estrogen (-), eccentric exercise (+) killed (after 1 h), compared with group 5 (Estrogen (-), eccentric exercise (+) killed (after 48 h). On the other hand, GSH-Px activities were also significantly decreased in groups 3, 4 and 5 compared with the control group. Leukocyte infiltration in liver increased after 48 hours compared with after 1 hour and estrogen supplementation was not able to prevent this infiltration. CONCLUSIONS Estrogen seemed to be not very effective to prevent eccentric exercise-induced liver damage.
