Abstract
Background: Quercus infectoria gall (Oak) has a long history of use as a medicinal plant. Andricus moreae galls arise on young branches of Quercus infectoria as a result of attack by bees.In this research, the antibacterial activity of methanol and acetone extracts of gall (Quercus infectoria) against Staphylococcus aureus, Bacillus cereus, B.subtilis strains was evaluated.
Material and methods: this empirical-experimental study was carried out in Autumn,2011. Getlls were collected from Lorestan oak forests and then were dried and grinded. Acetone and methanol extracts of the galls were prepared by maceration. The viscosities of 50,25,12.5,6.25,3.12 and 1.56 mg/ml were provided from methanol and aceton extracs by serial dilution method. The agar plate well diffusion method was used for antibacterial assay of different samples. Broth microdillution method was used for evaluate MIC and MBC of extracts. Data was analyzed by SPSS-16 software.
Results: All extracts demonstrated significant inhibitory effect against selected bacterial strains. There were statistically significant correlations between antibacterial activity and extracts concentration (p<0.05). Antibacterial activity of Andricus moreae gall methanol and acetone extracts against Staphylococcus aureus was more than Bacillus cereus, B.subtilis.
The MIC values of the Andricus moreae gall extracts ranged from 1.56 mg/ml to 3.13 mg/ml whereas the MBC values ranged from 3.13mg/ml to 6.25 mg/ml.
Conclusion: Methanol and acetone extracts of Andricus moreae were effective against all of tested bacteria. These findings show that methanol and acetone extracts of galls of Quercus infectoria may can be suggested as a natural antibacterial treatment .

Abstract
Background : Health systems in order to confirmity with changing conditions and responding to community needs, community needs to change and continuous improvement of their structure, function, and subsequent evaluationindicators. Therefore the purpose of this study was to evaluate effect of health system reform plan on performance indicators.
Materials and Methods : This study was a cross-sectional descriptive study using data from the years 1392 to 1394, the years before and after the implementation of healthcare reform was carried out. The population consisted of all hospitals of the Lorestan University of Medical Sciences (14 Hospitals). For data analysis using SPSS version 16, Paired sample T tests and Wilcoxon software were used.
Results: After health system reform plan all indicators had better than before and this development was significant in all cases. After health reform plan average length of stay was slightly increased (0.5%), although this was not significant statistically (P = 0.653). Before the health reform plan, the difference between the average bed occupancy indicator only for educational and non-educational centers were significant statistically (p = 0/05), but after the reform mean for all the indicators except indicator of average length of stay (p = 0/038), was significant.
Conclusion: The health system reform plan has been positive changes in indicators of hospital performance. Therefore, while considering the current trend of continuous improvement, the continuity of the project was advised based on the results of this study.
