The molecular mechanisms and pathogenesis of chronic hepatitis C (CHC) infection are unclear. Innate immune cells such as natural killer (NK) cells and dendritic cells are responsible from molecular mechanism of CHC. NK cell cytotoxicity such as TRAIL expression is important pathway for viral clearance. The aim of this study was to evaluate the relationship between HCV RNA and sTRAIL levels during the first 12 weeks of Peg-IFN and ribavirin treatment. Twelve treatment naive patients with CHC treated with Peg-INF and ribavirin were included in this study. Circulating sTRAIL and HCV RNA levels were measured at baseline, 4th and 12th week of treatment and their correlation was investigated. sTRAIL and HCV RNA levels decreased gradually with Peg-INF plus ribavirin treatment. The differences were significant between day 0, 4th week and 12th week of treatment. The expression of sTRAIL was correlated with HCV RNA level at baseline, at 4th and 12th week of treatment (P = 0.021 P = 0.012, P = 0.001 respectively). IFN binds to its receptor on the infected hepatocyte surface during Peg-IFN and ribavirin treatment. So the polarized phenotype of NK cell is not displayed and NK cell cytotoxicity such as TRAIL expression is blocked. We suggest that the decreased level of circulating sTRAIL may reflect increased binding to its ligand expressed on hepatocyte and decreased TRAIL production under the influence of Peg-IFN plus ribavirin treatment. Therefore TRAIL may be probably a immunologically predictive factor such as HCV RNA during treatment.

Methotrexate is a chemotherapeutic agent used for many cancer treatments. It leads to toxicity with its oxidative injury. The purpose of our study is investigating the medical ozone preconditioning and treatment has any effect on the methotrexate-induced kidneys by activating antioxidant enzymes in rats. Eighteen rats were divided into three equal groups; control, Mtx without and with medical ozone. Nephrotoxicity was performed with a single dose of 20 mg/kg Mtx intraperitoneally at the fifteenth day of experiment on groups 2 and 3. Medical ozone preconditioning was performed at a dose of 25 mcg/ml (5 ml) intraperitoneally everyday in the group 3 and treated with medical ozone for five more days while group 2 was received only 5 ml of saline everyday for twenty days. All rats were sacrificed at the end of third week and the blood and kidney tissue samples were obtained to measure the levels of TNF-, IL-1, malondialdehyde, glutathione and myeloperoxidase. Kidney injury score was evaluated histolopatologically. Medical ozone preconditioning and treatment ameliorated the biochemical parameters and kidney injury induced by Mtx. There was significant increase in tissue MDA, MPO activity, TNF- and IL-1 (P<0.05) and significant decrease in tissue GSH and histopathology (P<0.05) after Mtx administration. The preconditioning and treatment with medical ozone ameliorated the nephrotoxicity induced by Mtx in rats by activating antioxidant enzymes and prevented renal tissue.

The aim of this study is to determine the effects of medical ozone preconditioning and treatment on the methotrexate acute induced hepatotoxicity in rats that has not reports elsewhere. Eighteen rats were randomly assigned into three equal groups; control, Mtx and Mtx with ozone. Hepatotoxicity was performed with a single dose of 20 mg/kg Mtx to group 2 and group 3 at the fifteenth day. The medical ozone preconditioning was administered intraperitonealy in group 3 for fifteen days and more five days after inducing Mtx. The other rats of the group 1 and 2 received saline injection. At the twentyfirst day the blood and the liver tissue samples were obtained to measure the levels of liver enzymes ALT and AST, proinflamatory cytokines TNF-, IL-1, malondialdehyde, glutathione and myeloperoxidase. And the histolopatological examination was evaluated for injury score. In our study Mtx administration caused a significant increase on the liver enzymes ALT and AST, the tissue MDA and MPO activity and significant decrease in the tissue GSH. Moreover the both pro-inflammatory cytokines were significantly increased in the Mtx group. Medical ozone preconditioning and treatment reversed all these biochemical parameters and histopathological changes of the hepatotoxicity induced by Mtx. We conclude that medical ozone ameliorates Mtx induced hepatotoxicity in rats.

Minimally invasive surgical techniques have attracted interest in all surgical specialties since 1980. The thyroidectomy technique requires meticulous surgical dissection, absolute hemostasis, en bloc tumor resection and adequate visualization of the operative field, all of which can be accomplished with minimally invasive techniques.The study group comprised all patients undergoing MITS from its introduction in 2010 until July 2012. All data were prospectively recorded in the Elbistan Hospital and Suleyman Demirel University in Turkey. This study was designed to demonstrate our experience with mini-incision-technique in thyroidectomy.Over the 2-year period, 37 patients underwent bilateral MITS procedures. The procedure made with a small (2.5 cm) anterior incision made above the isthmus. The final diagnoses were benign multinodular goitre (37%), follicular adenoma (28%) incidental carcinoma (11%), Hashimotos thyroiditis (15%), Hurtle cell adenoma (5%), subacute thyroiditis (3%), residual thyroid-non carcinoma (2%), simple cyst (1%), diffuse hyperplasia (1%) and other (1%). Of the carcinomas, 80% were papillary thyroid cancer, 13% were follicular, and the remaining 7% were Hurtle cell carcinomas. We dont need to extend our incision in any cases. Two patients had temporary recurrent laryngeal nevre paresis and one patient had temporary hypocalcemia.It is not easy to demonstrate the advantages of MIT over conventional and video-assisted surgery. The main complications, such as nerve injury, hypoparathyroidism, or hemorrhage, are the same as in other surgical approaches. MIT has demonstrated advantages over conventional open approaches for both hemi- and total thyroidectomy and the benefits do not depend on the open or video-assisted approach. The anterior mini-incision approach can be performed with an operative time and postoperative complication profile equivalent to conventional thyroidectomy while providing excellent cosmesis with a 2 cm scar in both total thyroidectomy and lobectomies.
