Abstract
One of the useful function of melatonin is its protective effect against endogenous oxidants. The object of this investigation was to study the protective effect of melatonin on stress-induced gastric lesions.
Results: Our results show that pretreatment of animals with melatonin decrease the stress-induced gastric lesions dose dependently.
L-NAME, a nitric oxide synthesis inhibitor, potentiat the stress-induce gastric lesions and melatonin produced gastro-protective effect against concurrent stress and L-NAME-induced gastric lesions.
Conclusion: Our results indicate that melatonin may produce its gastro-protective effect Via increasing level of nitric oxide.

Abstract
Background: Ventilator associated pneumonia (VAP) is one of the serious complications of ventilatory support, occurring in ICUs. The aim of this study was to determine various risk factors associated with the acquisition of Acinetobacter infection and its antimicrobial susceptibility pattern.
Methods: This cross-sectional study was performed in the ICUs of Rasoul-e-Akram Hospital in Tehran, Iran during the year 2011. A total of 51 endobronchial aspirates from intubated patients who had been clinically diagnosed to have VAP were studied bacteriologically. The in vitro susceptibility was determined by disk-diffusion and broth microdilution MIC methods.
Results: Out of 51 patients with VAP, 35 (66.66%) had positive cultures for Acineto-bacter species. In vitro susceptibility test revealed that a high percentage of isolates were resistant to imipenem, piperacillin-tazobactam, third generation cephalosporines, and aminoglycosides.
Conclusion: The antimicrobial resistance of gram negative bacteria, particularly Acine-tobacter species, is increasing and preventive measures need to be taken as a matter of urgency.

Abstract
Background: Breast cancer is one of the most important causes of death in women. One of the various gene expression involved in breast cancer is human epidermal growth factor receptor 2 (HER2/neu) gene expression increases. Factors of dietary affect on regulation of hormone secretion and the rate of breast cancer. One of these factors is amount and type of fats in diet. Gamma-linolenic acid (GLA) and Docosah-exaenoic acid (DHA) are members of poly unsaturated fatty acids. In this study, effects of dietary GLA and DHA alone or together with paclitaxel on treatment of mice mammary carcinoma has been evaluated.
Methods: Thirty female balb/c mice were divided in six groups randomly. Carcinoma-tous mass induced by tumor implantation method. Spontaneous breast adenocarcinoma of mice were used as tumor stock. The tumors of these mice were removed aseptically, dissected into 0.5 cm3 pieces. These pieces were transplanted subcutaneously into their right flank. GLA and DHA added to the mice diet two week prior to tumor implanta-tion. At the end of intervention, tumors were removed and HER2 gene expression was measured. The weight of animal and tumor volume measured weekly.
Results: It was not significant change in the weight of animals that consumed DHA and DHA with taxol. Tumor volume in those groups that received corn oil with taxol (P<0.01), DHA (P<0.05) and DHA with taxol (P<0.001) showed significant decrease in comparison with control group. HER2 gene expression in DHA with taxol decreased significantly in comparison with control group (P<0.05).
Conclusion: Consumption of DHA oil with taxol causes decrease the volume of carcin-oma mass. The future studies with large number of sample is needed to support this finding.
