Abstract
INTRODUCTION Alcohol consumption is frequently associated with gastric mucosal lesions. The purpose of this study was to determine the effect of Coenzyme-Q10 (CoQ10) supplementation on the ethanol-induced gastric mucosal damage in a rat model. MATERIAL AND METHOD Sixty-four female wistar albino rats were randomly divided into 8 groups (n = 8). Studies were performed in ethanol induced gastric ulcer model in Wistar albino rats. Famotidine at a dose of 5 mg/kg or 20 mg/kg and CoQ10 at a single dose of 10 mg/kg or 20 mg/kg and 30 mg/kg for 7 days were administered as pretreatment. All the rats in study groups received 2 ml/kg ethanol 95 % intragastrically, 30 minutes after pretreatment. Four hour after ethanol administration, all rats were sacrificed and their stomachs were removed under ketamin anaesthesia. Gastric protection was evaluated by measuring the ulcer index, MDA concentrations, and histopathological studies. RESULTS AND DISCUSSION Rats pretreated either with famotidine or CoQ10 had significantly diminished gastric mucosal damage which was assessed with gross and microscopic analysis (p < 0.00625). MDA levels were significantly lower in famotidine 20 mg/kg and CoQ10 pretreatment for 7 days group (p < 0.00625).

Abstract
The molecular structure and vibrations of 5-[(3-methylphenyl) (phenyl) amino] isophthalic acid (MePIFA) were investigated by infrared and Raman spectroscopies, UV-Vis, (1)H and (13)C NMR spectroscopic techniques and NBO analysis. FT-IR, FT-Raman and dispersive Raman spectra were recorded in the solid phase. (1)H and (13)C NMR spectra and UV-Vis spectrum were recorded in DMSO solution. HOMO-LUMO analysis and molecular electrostatic potential (MEP) analysis were performed. The theoretical calculations for the molecular structure and spectroscopies were performed with DFT (B3LYP) and 6-311G(d,p) basis set calculations using the Gaussian 09 program. After the geometry of the molecule was optimized, vibration wavenumbers and fundamental vibration wavenumbers were assigned on the basis of the potential energy distribution (PED) of the vibrational modes calculated with VEDA 4 program. The total (TDOS), partial (PDOS) density of state and overlap population density of state (OPDOS) diagrams analysis were made using GaussSum 2.2 program. The results of theoretical calculations for the spectra of the title compound were compared with the observed spectra.

Abstract
BACKGROUND Ulcerative colitis is a chronic inflammatory condition of the colon, and reactive oxidative metabolites (ROMs) play an important role in its pathogenesis. Alternative therapies such as herbal remedies are increasingly being used in the treatment of ulcerative colitis for better clinical outcome of ulcerative colitis and less adverse effects. Echinacea has many features including antioxidant and wound-healing properties. Hence, the present study was undertaken to evaluate the protective effect of Echinacea spp. on experimental colitis model induced by acetic acid in Wistar albino rats. METHODS Acute colitis was induced by intrarectal administration of acetic acid. Rats were divided into four groups, namely control, Echinacea-administered, Echinacea-administered-colitis and colitis. Malondialdehyde and total antioxidant status were assayed in tissue samples. Histopathological evaluation was also performed. RESULTS Macroscopic and microscopic scores were significantly higher in colitis group compared to control, Echinacea and Echinacea-colitis groups (p < 0.001). There was no significant differences in respect of macroscopic and microscopic scores between control, Echinacea and Echinacea-colitis groups (p > 0.3, p > 0.22). Malondialdehyde levels were elevated in colitis group compared to other groups (p < 0.001). Total antioxidant status was significantly higher in Echinacea group compared with other groups and also significantly higher in Echinacea-colitis group compared with colitis group (p < 0.001, p < 0.001, respectively). CONCLUSION Echinacea may possibly have some therapeutic usefulness in the management of ulcerative colitis (Tab. 2, Fig. 4, Ref. 35).

Abstract
Ionizing radiation causes its biological effects mainly through oxidative damage
induced by reactive oxygen species. Previous studies showed that ozone oxidative
preconditioning attenuated pathophysiological events mediated by reactive oxygen
species. As inhalation of ozone induces lung injury, the aim of this study was
to examine whether ozone oxidative preconditioning potentiates or attenuates the
effects of irradiation on the lung. Rats were subjected to total body
irradiation, with or without treatment with ozone oxidative preconditioning
(0.72 mg/kg). Serum proinflammatory cytokine levels, oxidative damage markers,
and histopathological analysis were compared at 6 and 72 h after total body
irradiation. Irradiation significantly increased lung malondialdehyde levels as
an end-product of lipoperoxidation. Irradiation also significantly decreased
lung superoxide dismutase activity, which is an indicator of the generation of
oxidative stress and an early protective response to oxidative damage. Ozone
oxidative preconditioning plus irradiation significantly decreased
malondialdehyde levels and increased the activity of superoxide dismutase, which
might indicate protection of the lung from radiation-induced lung injury. Serum
tumor necrosis factor alpha and interleukin-1 beta levels, which increased
significantly following total body irradiation, were decreased with ozone
oxidative preconditioning. Moreover, ozone oxidative preconditioning was able to
ameliorate radiation-induced lung injury assessed by histopathological
evaluation. In conclusion, ozone oxidative preconditioning, repeated low-dose
intraperitoneal administration of ozone, did not exacerbate radiation-induced
lung injury, and, on the contrary, it provided protection against
radiation-induced lung damage.

Abstract
BACKGROUND We aimed to investigate the effects of nitrous oxide on plasma total homocysteine and vitamin B12 levels in patients with or without methyltetrahydrofolate reductase (MTHRF) gene mutation. METHODS After obtaining the ethics committee approval and written informed consents of patients, 93 patients between 18-70 years of age scheduled for surgery anticipated to last 1-4 hours were enrolled in the study. Patients with contraindications for nitrous oxide use were excluded. Preoperatively, blood samples were obtained from all patients for the determination of MTHFR gene mutation. Anesthesia induction was achieved with 3 mg.kg-1 of propofol and 1 µg.kg-1 of fentanyl. Anesthesia maintenance was performed with sevoflurane and with a carrier gas composed of 40 % O2 and 60 % N2O. Venous blood samples were obtained after venous canulation, and 24 hours after extubation for the analysis of plasma total homocysteine, vitamin B12 levels. RESULTS Eighty-one patients were included in the study. Postoperative vitamin B12 levels were found to be significantly lower when compared with their preoperative levels (p<0.05). It was found that MTHRF gene polymorphism had no significant effect on postoperative plasma total homocysteine and serum vitamin B12 levels (p>0.05). Postoperative plasma total homocysteine levels were found to be significantly different between patients with operation times under and over 3 hours (p=0.028). CONCLUSIONS We conclude that MTHRF gene polymorphism had no significant effects on postoperative plasma total homocysteine levels. However, we found that homocysteine levels might rise in patients who received general anesthesia with nitrous oxide for longer than 3 hours (Tab. 7, Ref. 26).

Abstract
PURPOSE To compare tear film osmolarity (TFO) between patients with diabetes mellitus (DM) and normal healthy individuals. METHODS In this prospective case-controlled study, the TFO in 46 normal subjects (control group) and 55 patients with DM (study group) was evaluated. TFO in milliosmole (mOsm) was measured by using an auto-osmometer. The serum levels of glycosylated hemoglobin (HbA1c) and blood glucose in all participants were also measured. Mean outcome measures were TFO and its relationship with HbA1c level and duration of DM. RESULTS Mean TFO was 320.40 ± 21.80 mOsm/l in the study group and 308.22 ± 18.16 mOsm/l in the control group (p < 0.001). The TFO values were significantly associated with duration of DM (r = 0.476, p < 0.001), but no significant correlation was found with HbA1c level (r = 0.225, p = 0.114). CONCLUSIONS The study shows a significantly higher TFO in patients with DM than in the healthy controls. TFO also correlates with the duration of DM.
