Background: Septicemia is a life threatening status and needs rapid antibiotic treatment. Enterobacteriacea are one of the most important causes of septicemia. So this study is therefore aimed to evaluate antibiotic susceptibility of enterobacteriacea isolates in blood cultures in Shariati Hospital, Tehran, Iran.
Methods: This retrospective study was performed on 138 patients with positive blood culture in Shariati Hospital, Tehran, Iran in 2004, using disk diffusion and Macfarland standard.
Results: Prevalence of isolated enterobacteriacea was respectively E. coli (n=74, 53.6%), Klebsiella (n=37, 26.8%), Enterobacter (n=21, 15.2%), Citrobacter (n=4, 2.9%), Salmonella paratyphi (n=1, 0.7%) and Proteus mirabilis (n=1, 0.7%). The most antibiotic susceptibility among enterobacteriaceaes was ciprofloxacin (60.4%), cloramphenicol (56.8 %) and gentamycin (49.3%). The most antibiotic resistance were seen among cephalotine (78%), cotrimoxazole (62.3 %) and ceftriaxon (57.5 %).
Conclusions: Due to dissimilarity between antibiotic consumption in laboratories and hospitals, it seems that to reach more proper conclusions and choosing better strategy for antibiotic consumption, cooperation should be between laboratories and physicians, plus synergism between drug prescription and antibiotic discs in laboratories.

Background and Aim: Candida species are among the most common causes of opportunistic fungal diseases. Among Candida species, Candida albicans is responsible for most infections. Having many strains, C.albicans is highly polymorph. C. dubliniensis is very similar to albicans species both morphologically and physiologically. For an infection to occur, cell wall proteins play an important role as they enable yeasts to adhere to host cells and begin pathogenesis. Therefore, we decided to extract these proteins and examine them through molecular methods of protein analysis. Finally we came up with the idea of a modified staining in our analysis.
Materials and Methods: Initially cell wall proteins of two C. albicansstrains (CBS 562 & PTCC6027) and one C. dubliniensis strain (CBS 7987) were extracted by using a solution of beta-mercaptoethanol and ammonium carbonate. After dialysis, SDS gel electrophoresis was performed on the protein extract. Bands were then visualized by using three different staining methods among which one method was modified by us.
Results: By using Coomassie Brilliant Blue staining method, proteins with molecular weight of 42, 66.2 and 200 kDa were detected. By using Silver staining method, proteins with molecular weight of 21.5, 28.5 and 37 kDa were detected. However, using combined staining methods visualized more bands resulting improved detection.
Conclusion: To answer many questions about fungal diseases, fungi cell wall proteins are necessary to be examined. A simple method to enhance such molecular studies is the use of a modified staining method that combines both Coomassie Brilliant Blue and Silver staining.

Background and Aim: Hospitals are among the most important establishments providing health services, in which -- due to special hazards -- the observance of safety principles is of great importance. This research aimed to study the safety conditions at educational hospitals of Shiraz University of Medical Sciences(SUMS).
Materials and Methods: This cross-sectional descriptive study was conducted in all educational hospitals in Shiraz and their safety status was investigated using safety audit technique. To this end, audit checklists were prepared and completed through observation, interview with managers and officials of various departments as well as studying the related documents. Then, based on the realization of safety requirements, hospitals were classified into three levels of poor (lower than 50%), medium (5o-75%), and good (higher than75%).
Results: The mean realization of safety requirements in the studied hospitals was 58 percent. The highest and lowest levels of realization of safety requirements were related to radiation safety and safety management, respectively. Safety status was evaluated as poor in 25% and medium in 75% of the studied hospitals.
Conclusion: The safety conditions of the studied hospitals, especially as regards safety management, emergency response plan, and fire safety aspects were relatively poor. The most important reason for that was the lack of clarity of responsibilities and of safety organizational structure. To improve the safety status, hospitals are required to establish the Occupational Health and Safety Management System (OHSAS 18001).

Materials and Methods: This is a survey study. Data were collected by a self-made questionnaire and the population included postgraduate students of Qazvin University of Medical Sciences in the first semester of 94-95.
Results: More than half of the students stated that images and videos have an average or more-than-average effect on their learning achievements. There is no significant relationship between students’ fields of study and their feeling the need for specialized images and videos. To get advice, they refer more to their professors or classmates than to librarians. A large number of responding students had not heard even the names of specialized image-and-video databases or they had never used them before. Low-speed internet and filtering of sites are the most important factors in students’ failure to access their required images and videos while students themselves have ranked ‘unfamiliarity with specialized databases’ as the fourth important factor.
Conclusion: The students know the importance of images and videos in learning achievements, but since they don’t know the professional databases and don’t have an appropriate interaction with librarians, they resort to general search-engines and, as a result, they face with blocked sites and are deprived from what they really want.
