Spring summer 2010, Vol.4, No.1 /72 Medical Laboratory Journal Evaluation of Cholesterol Panel Changes in Fish Consumers in the West of Mazandaran Province, Iran Abstract Bachground and objectives: Eating fish reduces low-density lipoprotein cholesterol (LDL-C) and increases high density lipoprotein cholesterol (HDLC). Because of different factors, such as physiological conditions and kind of fish consumption, the findings can be different. We decided to investigate the reducing effect of regular fish eating on plasma lipids and lipoproteins of different groups. Material and Methods: the Subjects were 50 clients (control group) with normal Lipid and 50 ones with high Lipid (case group). The subjects, with different sex and age, were asked about smocking, heart disease and diabetes. Fast blood samples were collected and analyzed for total cholesterol (TC), low and high density lipoprotein cholesterol (LDL-C, HDL-C and VLDL), TG, HDLC, apolipoprotein A and B. Results: The data shows a significant difference in cholesterol, LDL, apoA and VLDL levels in moderate and high consumers. (P<0.005). In subjects with high LDL, the kind of fish consumption was stir- fried (0.96%) and grilled and boiled (7.4%). The Subjects with high-fish consumption is 32.2% for normal LDL Level and Just 1.1% for ab normal Level. There is no significant effect on HDL and apoB levels due to fish intake in any dosage. The relation is seen between abnormal lipid and rare fish consumption. Conclusion: Present study shows the reducing effect of fish consumption on cholesterol level and LDL-C. More studies are needed to be conducted to evaluate the type of faty acids in fishes. . Key words: Fish, dietary, cholesterol panel.

Abstract Bachground and objectives: Dientamoeba fragilis is a habitant protozoa in human colon causing clinical symptoms, such as local stomach pain, weight loss, lack of appetite and flatulence. It is important to diagnose this infection correctly and differentiate it from other Protozoa. In this study PCR and Iron Hematoxylin methods were used to detection of this protozoa in Chalous Medical centers refers in 2010. Material and Methods: The stool samples (n=302) of this cross-sectional study were selected via cluster random sampling. After wet mount study the samples were preserved in PVA (for staining) and Ethanol (for molecular). The samples were studied both Staining and Molecular methods. Sensitivity and specificity were assessed. Results: Of 302 samples, six of them are positive via staining method (1.99%) and five by molecular method. All negative results with staining method are also negative with PCR. Contamination with E.coli in 2 samples and with Balstocystis homonis were seen in one sample. Sensitivity and specificity of PCR was 85% and 100% respectively. Conclusion: The discrepancy between two methods maybe caused by observer errors in staining method and unsynchronized molecular and microscopic studies.

Abstract Background and Objective: The hormonal responses are different, according to type, intensity and the duration of training. We aimed to compare the effect of endurance and resistance training in untrained men on the level sexual hormone including testosterone, estradiol, and on sex hormone binding globulin (SHBG). Material and Methods: this study was conducted on male Student Volunteers divided randomly into three groups of eight members, including endurance, resistance and control. To measure the variables, we performed sampling before and after the training program. Results: the levels of testosterone and estradiol, in both groups have a significant (p<0.05) increase and decrease respectively. SHBG level was significantly increased only in endurance group (p<0.05), But LH level was meaningfully increased only in the resistance group (p<0.05). Conclusion: The endurance and resistance training can increase the production of testosterone .Increased testosterone and decreased estradiol in men lead to sperm production and improve fertility.

Background and Objective: Nosocomial infection is one of the main factors of mortality in hospitals . One of the most important measures to control infection in hospitals  is sampling of equipment and  culturing the samples . This study aimed to investigate the prevalence of gram-negative bacilli obtained from the equipment of the hospital wards .

Material and Methods: This Descriptive study was carried out on 488 specimens taken from medical and non-medical devices and equipment of various wards, via census sampling. the samples taken by sterile swabs in Tryptic Soy Broth (TSB) were inoculated in blood agar and Eosin-Methylene Blue agar, and by biochemical standard tests the isolated colonies  were identified.

Results: Of 488 isolates, 157 (32.17%) were positive for the presence of gram-negative bacilli. The highest bacterial contamination was related to Enterobacter (37.58%). Of  hospital wards, the highest infection related to the surgical wards (19.75%), and the highest contamination is related to laryngoscope blades (12.74%) and ECG sensor device and the monitoring interface (7%).

Conclusion: Microbial infection with gram-negative bacilli  is an overwhelming condition  in hospital equipment.

Background and Objective: Bacterial infections are of the leading causes of morbidity and mortality in ICU patients with underlying immunodeficiency. This study aimed to determine the frequency of microorganisms in patients admitted to the ICU of Panje Azar Hospital in Gorgan.

Material and Methods: This cross-sectional study was conducted on the patients admitted in three wards, each having at least 48, of ICU in Panje Azar Hospital in Gorgan. All microbial cultures requested by patientschr('39') physician were recorded.

Results: In ICU positive cultures were 53.9%.  The number was 16 for Staphylococcus coagulase negative,  15 for  Enterococci  , 11 for Yeast, 11 for E.Coli, 9 for Enterobacter  , 8 for streptococcus, 5 for staphylococcus aureus. The highest  percentage was related to coagulase-negative staphylococci (16.5%) and the lowest to Alcaligenes, Diphtheroids, Acremo bacteria , Serratia with one positive case.

Conclusions:  the incidence of bacterial contamination in ICU patients compared to other parts of country is not different significant.  While it is far from world standard, it is essential that many efforts be done to reduce the level of infection.

       Background and Objective: Staphylococcus aureus is the most common and important infectious agent. This bacterium can enter the bloodstream and cause some complications in the intensive care unit (ICU).This organism can frequently be found in the nose and transmitted by the carriers. This study aimed to determine the efficiency of eradicating S. aureus from the nose of ICU personnel in reducing the risk of S. aureus infections in the Panje Azar Hospital in Gorgan, Iran.

        Methods: Sampling was done using sterile swabs collected from the anterior nasal passages.All samples containing Gram-positive cocci were sent to the laboratory of Faculty of Medicine for identification and evaluation of methicillin resistance. All S. aureus nasal carriers were treated with mupirocin ointment b.d for 5 days. The Samples were cultured again after five weeks to evaluate the eradication of S. auerus from the nose of subjects.

       Results: Overall, seven ICU personnel (11.7%) were S. aureus carriers. Two isolates (3.3%) were found as methicillin resistant using both methods of disc diffusion and PCR. The frequency distribution of positive cases indicated a significant difference in terms of work experience (P = 0.012).

        Conclusion: The findings show that treatment of carriers with 2% mupirocin topical ointment eradicates S. aureus from the nose. No S. aureus isolates was found in reculture of nasal samples. Treatment of healthy carriers can significantly reduce the risk of infections caused by the bacterium in the ICU.

          Background and Objectives: Staphylococcus aureus is one of the most common causes of morbidity and mortality among intensive care unit (ICU) patients. Nasal carriage is one of the main routs of S. aureus transmission between hospital personnel and patients. The objective of this study was to evaluate the efficacy of mupirocin ointment in eradication of nasal carriage of S. aureus in the ICU staff and patients of Panje-Azar hospital in Gorgan, Iran.
          Methods: In the first three months of the study (January to March), the prevalence of S. aureus among ICU patients was determined by routine microbiological and biochemical testing. Nasal samples were taken from ICU staff and all patients recently admitted to the ICU. Mupirocin nasal ointment (2%) was applied for treatment of S. aureus nasal carriers. Post-treatment sampling was done after five weeks. During the next three months, the presence of S. aureus and rate of resistance to methicillin was evaluated in new patients admitted to the ICU using the method used previously.
          Results: Of 60 samples from the ICU staff, seven (11.7%) samples were positive for S. aureus. Moreover, of 240 samples from the ICU patients, two samples were found as S. aureus-positive. Of the nine S. aureus-positive isolates, only two (22.2%) were methicillin-resistant S. aureus (MRSA). In the pre-intervention sampling, only five samples (2.8%) were identified as S. aureus, two of which were MRSA. However, treatment with mupirocin ointment eradicated nasal carriage of S. aureus and no isolate was found after the intervention.
          Conclusion: Our finding showed that mupirocin nasal ointment is highly effective in eradication of S. aureus nasal carriage and subsequently contribute to reduction in frequency of nosocomial infections in the ICU.

Background and objectives: Staphylococcus aureus is a frequent cause of hospital- and community-associated infections on a global scale. This organism is responsible for causing an extensive range of diseases and many of them are capable of biofilm formation for their survival. By this method, treatment of them with antibiotics become very difficult and antibiotic resistance is another rising concern.
Material and Methods: The clinical samples were collected and examined for Staphylococcus aureus by microbiological and biochemical tests. Then, the biofilm formation in Staphylococcus aureus isolates was detected by microtiter plate. Using SYBR Green Real-Time PCR, the expression of PSM was determined.
Results: A total of 60 strains of Staphylococcus aureus were isolated from clinical isolates. Of them, 47 strains (78.3%) were identified biofilm producing and the others were considered negative for biofilm formation. After real-time PCR testing to detect PSM, it was determined that 100% of the strains were positive for biofilms and PSM genes. The results of phenotypic and genotypic tests of biofilm were closely related to each other and the expression of PSM B gene was 80%. It was found that 100% of strains were biofilm producing and PSM B gene was present in 78.3% (47 strains) of them.
Conclusion: The prevalence of biofilm production in Staphylococcus aureus strains isolated from clinical samples was high, so it is highly important to monitor the prevalence of these organisms in hospitals and community as well as their antimicrobial resistance.
