Abstract
The study aimed to investigate the effect of erdosteine on middle ear effusion in rats through mediating the Toll-like receptor 4 (TLR4) signaling pathway. Rats were injected with endotoxin to prepare the model of acute secretory otitis media (SOM). Then, they were divided into an acute SOM model group (model group, n = 15) and erdosteine treatment group (18 mg/kg, gavage, treatment group, n = 15). Besides, a normal group (n = 15) was set up. Two weeks later, routine biochemical indicators such as aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were detected. The inflammatory effusion due to otitis media was scored. The content of myeloperoxidase (MPO), matrix metalloproteinase (MMP), and tumor necrosis factor-beta (TNF-β) in middle ear lavage fluid was detected via enzyme-linked immunosorbent assay (ELISA). Additionally, histomorphological changes were observed with the help of hematoxylin-eosin (HE) staining, and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blotting assays were carried out to measure the expression levels of TLR4 pathway genes and proteins as well as the messenger ribonucleic acid (mRNA) expression levels of key factors for otitis media (mucin 2 (MUC2) and MUC5A). In the model group, the levels of AST, ALP, and glutamic-pyruvic transaminase (GPT) were significantly increased (p < 0.05). Besides, the content of MPO, MMP, and TNF-β was overtly raised in the model group (p < 0.05), while it was notably lowered in the treatment group (p < 0.05). In the treatment group, the cilia were slightly swollen, and inflammatory cells were fewer. The mRNA levels of MUC2, MUC5A, and pathway genes TLR4 and c-Jun N-terminal kinase (JNK) were elevated in the model group. In addition, the protein assay results revealed that the protein levels of TLR4 and JNK were evidently increased in the model group. Erdosteine can treat the middle ear effusion in rats by repressing the activation of the TLR4 signaling pathway.

Abstract
We aimed to investigate the effects of grape seed extract (GSE) and vitamin E (Vit E) on oxidative stress and apoptosis in the hippocampus of streptozotocin-induced diabetic rats. In Control, Diabetic, and Diabetic treated with GSE (Diabetic+GSE) and vitamin E (Diabetic+Vit E) groups, oxidative stress index (OSI), TUNEL staining and Bcl-2, Bcl-XL, Bax, caspase-3, -9, and -8, Cyt-c, TNF-α, and NF-κB gene expressions were evaluated. OSI was significantly increased in the plasma and hippocampus of the Diabetic compared to Control group and decreased in Diabetic+GSE and Diabetic+Vit E groups compared to Diabetic. TUNEL positive neurons significantly increased in the hippocampus of the Diabetic group compared to Control and decreased in Diabetic+GSE (more prominently) and Diabetic+Vit E groups compared to Diabetic. In the hippocampus of the Diabetic group, Bcl-2 and Bcl-XL gene expressions were significantly decreased; Bax, caspase-3, -9, and -8, Cyt-c, TNF-α, and NF-κB gene expressions were significantly increased compared to Control. In Diabetic+GSE and Diabetic+Vit E groups, Bcl-2 gene expressions were significantly increased; Bcl-XL gene expressions did not differ compared to the Diabetic group. The expression of Bax, caspase-3, -9, and -8, Cyt-c, TNF-α, and NF-κB genes in the Diabetic+GSE group and the expression of caspase-3 and -9, TNF-α, and NF-κB genes in the Diabetic+Vit E group were significantly decreased compared to Diabetic. In conclusion, GSE (more prominently) and vitamin E decreased oxidative stress and neuronal apoptosis occurring in the hippocampus of diabetic rats.

Abstract
Experimental data on the effect of nicotine on cerebral microvessel thrombosis is lacking. Therefore, this study was carried out to elucidate the effects of nicotine on platelet aggregation in cerebral (pial) microcirculation of the mouse, and the possible protective effect of vitamins C and E. Male TO mice were divided into six groups, and injected i.p. with saline as a control, nicotine (1 mg/kg), vitamin C alone (100 mg/kg), vitamin E alone (100 mg/kg), nicotine plus vitamin C or nicotine plus vitamin E, all for one week before the experiment. After one week, platelet aggregation in cerebral microvessels of these groups of mice were studied in vivo. The appearance of the first platelet aggregation and total blood flow stop in arterioles and venules were timed in seconds. In the animals treated with nicotine, venules did not show any alteration in the platelet aggregation time in comparison to the control animals. However, in arterioles platelet aggregation time was significantly accelerated (p<0.001) in nicotine-treated animals as compared to controls. Both vitamins C and E prevented the shortening of arteriolar platelet aggregation time significantly (p<0.001) when applied with nicotine but not alone. It can be concluded that nicotine enhances the susceptibility to thrombosis in the cerebral arterioles in vivo and that vitamins C and E have alleviating effect on nicotine-induced thrombotic events in mice pial microvessels.

Abstract
PURPOSE We aimed at investigating the effect of erdosteine administration on amikacin induced visual evoked potentials (VEPs) alterations in rats. METHODS For this purpose, forty male Wistar rats were divided into 4 groups: control, amikacin treated, erdosteine treated, and amikacin + erdosteine treated. Amikacin (600 mg/kg/day) was applied as a single dose of intramuscular injection for 14 days, and 10 mg/kg/day erdosteine was given by gastric gavage for the same period. We recorded all VEP components and measured plasma thiobarbituric acid reactive substance (TBARS) levels in all groups. RESULTS Amikacin increased the latencies of all VEP components (P1, N1, P2, N2, and P3) and elevated plasma TBARS levels compared with control and erdosteine treated rats (p < 0,01). However, prolonged latencies of VEP components in amikacin treated rats returned to control levels after erdostein administration. Treatment of amikacin and erdosteine together significantly decreased plasma TBARS levels (0.05 ± 0.018 nmol/g protein) compared with amikacin group (0.12 ± 0.038 nmol/g protein). CONCLUSIONS These results show that erdosteine has a protective effect on amikacin induced changes in the visual system.

Abstract
Background Epidemiological and in vitro studies suggest that antioxidants such as quercetin and vitamin E (VE) can prevent lung tumor caused by smoking; however, there is limited evidence from animal studies. Methods In the present study, Swiss mouse was used to examine the potential of quercetin and VE for prevention lung tumor induced by smoking. Results Our results suggest that the incidence of lung tumor and tumor multiplicity were 43.5% and 1.00 ± 0.29 in smoking group; Quercetin has limited effects on lung tumor prevention in this in vivo model, as measured by assays for free radical scavenging, reduction of smoke-induced DNA damage and inhibition of apoptosis. On the other hand, vitamin E drastically decreased the incidence of lung tumor and tumor multiplicity which were 17.0% and 0.32 ± 0.16, respectively (p < 0.05); and demonstrated prominent antioxidant effects, reduction of DNA damage and decreased cell apoptosis (p < 0.05). Combined treatment with quercetin and VE in this animal model did not demonstrate any effect greater than that due to vitamin E alone. In addition, gender differences in the occurrence of smoke induced-lung tumor and antioxidant intervention were also observed. Conclusion We conclude that VE might prevent lung tumor induced by smoking in Swiss mice.

Abstract
Coenzyme Q_{10} (CoQ_{10}) is an obligatory element in the mitochondrial electron transport system and functions as a potent antioxidant of lipid membranes. In-vivo and in-vitro studies indicate an involvement of CoQ_{10} in inflammatory pathways. Here we studied in the human monocytic cell-line THP-1 the influence of CoQ_{10} on LPS-induced secretion of the pro-inflammatory chemokines Macrophage inflammatory protein-1 alpha (MIP-1alpha), Regulated upon activation, normal T cell expressed and secreted (RANTES) and Monocyte chemoattractant protein-1 (MCP-1). In comparison to unstimulated cells, LPS leads to 22-, 3- and 4.5-fold higher levels of MIP-1alpha, RANTES and MCP-1 in the cell culture medium, respectively. Pre-incubation of cells with 10 microM CoQ_{10} resulted in a significant decrease of LPS-induced MIP-1alpha and RANTES secretion to 55.04% (p = 0.02) and 76.84% (p = 0.04), respectively. In conclusion, CoQ_{10} reduces the LPS-induced secretion levels of the pro-inflammatory chemokines MIP-1alpha and RANTES in the human monocytic cell line THP-1. These data suggest that CoQ_{10} possesses anti-inflammatory properties.
