Abstract
71/Spring summer 2010, Vol.4, No.1 Medical Laboratory Journal The Effects of Anabolic-Androgenic Steroid Drugs Consumption on Blood Factors in Bodybuilder’s Athletes in Jahrom,Iran Abstract Background and objectives: Mass media and the press present documentary reports of taking illegal energetic drugs by athletes who are tempted to enhance their performance. The present study aims at determinrg the effect of two illegal drugs on the athletes, blood factors. Material and Methods: The participants are 20 volunteer athletes selected unrandomly, 10 as a control and 10 as an experimental group. First, their blood samples were obtained from the medial cubital vein of left hand and then they were subjected to body building exercises for six weeks. The control group did not take any drugs while, the experimental one took oxymetholone steroids and methandrostenolone orally, based on pre – determined schedule during the exercises. During this period, Venipuncture was carried out for five times and the effects of drug on the blood factors were investigated. Finally, we analyses the findings by statistical Tests. Results: The results show that the levels of HCT (51.1 % vs. 46%), Hb (16.6 g/dl vs.15.6g/dl) and Reticuloeyte (0.9% vs. 0.5%) are increased significantly (P<0.05). there is no meaningful differences in the other blood factors such a WBC, MCV, MCHC an MCH. Conclusion:Based on this, findings, taking oxymetholone and methandrostenolone, which have prominent effects on the body functions, result in major changes in some blood factors such Hb, Hct and Retic. Key Words: Oxymetholone, Methandrostenolone, blood factors Dorry K (MSc) Instructor ofMicrobiology, Islamic Azad University, Jahrom Branch Nedaeinia R (MSc) Microbiology, Undersecretary for Food and Drug, Isfahan University of Medical Sciences Hemayatkhah JahromieV (PhD) Instructor ofMicrobiology, Islamic Azad University, Jahrom Branch NaderianM (PhD) Assistant Professor of Physical education, Isfahan University Corresponding: Dorry K Email: s.dorry@gmail.com

Abstract
Abstract Bachground and objectives: The ability of adherence to the surface of host cell is very critical in the colonization of microbial pathogens. It has been revealed that E. coli strains that infect urinary tracts have different fimbrea such as I, S, FIC, Dr, and fimbrial adhesions. Material and Methods: In this study, 363 urine samples were obtained from patients with urinary tract infections reffered to clinical laboratories in Western areas of Tehran ,2008-2010 by using biochemical tests,200 samples were confirmed to be E.coli.First, DNA was extracted by boiling method and then the presence of fimbria fim, sfa, pap, foc, and afa genes tested by PCR. Results: In 200 samples, the frequency of fimbria fim, sfa, pap, foc, and afa genes are188 (%94 ), 34 (%17), 20 (%10), 61 (%31) and 71 (%35.5), respectively. Conclusion: The resultes show that FIM ans SFA are the most fimbrial genes of E. coli isolated from urine samples .This information can be valuable in etiology of urinary tract infection (UTI), UTI administration, and making of new vaccines. Key words: Urinary tract infection, fimbria, Uropathogenic E. coli (UPEC)

Abstract
Abstract Background and objectives: Pathogens can be transferred via the hands of the personnel not only to themselves but also to their families or to the patient causing infection especially nosocomial infections. Microbial contamination of hand is caused by contact with patients and their environments or usual devices in the workplace. It seems that contamination of computer devices and handsets are more in hospital than official buildings. The aim of this study was to assess and compare the microbial contamination of computer keyboards, mouse and telephone receivers in a hospital department and an official building. Material and Methods: the sterile swab samples obtained from 32 keyboards, 31 computer mouse and 30 telephone receivers in the official building of Mashhad medical university and central laboratory of Imam Reza hospital were cultured on Blood agar and MacConkey agar plates. Results: Out of 64 samples from the official building, we identify 83 microbial germs. The most common ones are gram-positive Bacilli (n =34, 40.95%) and coagulase-negative Staphylococci (n = 32, 32.53%). Of 29 samples of central laboratory, there are 33 microbial germs .The most common of them are grampositive Bacilli (n = 19, 57.57%) and coagulase-negative Staphylococci (n = 7, 21.21%). Overall, microbial contamination of the computer equipment and handsets is not statistically meaningful (P< 0.05). Some germs like diphtheroid are not existed in laboratory, but two cases of Aspergillus are found. Conclusion: The presence of most of the germs on these devices is due to dusting or normal flora transferred via staffs’ hands. Only two of them, coagulase-positive Staphylococci and Aspergillus, should be considered carefully because they may cause serious infections in staff, their families or patients.

Abstract
Background and Objective: Cross-transmission of microorganisms by the hands of health care workers is considered as a main transmission route of nosocomial infections. The aim of this study was to investigate the microbial contamination of health-care worker’s hands while going out of hospital.
Material and Methods: Wearing the sterile glove with liquid culture, we obtained 100 Samples from the staff’s hands of three departments (clerical department, emergency ward and central laboratory) of Emam Reza hospital. After that, the samples were cultured.
Results: Of all personnel, 40% have the habit of washing their hands. Of these, 95 percent wash their hands with water and soap, and 5 percent with alcohol rubs. Of 100 cultured samples, 90 have microorganisms including non-pathogen gram-positive bacillus (29%), coagulase-positive staphylococcus (39%), coagulase-negative staphylococcus (47%), Enterococci (3%), micrococcus (25%) and candida (3%). Contamination in those who had not washed their hands is 62.6% and in those who washed is 37.7% (P=0.04).
Conclusion: Hands of health-care workers become progressively contaminated by the potential pathogens during daily activities. To reduce the rate of contamination, it is helpful if we ask staff to wash their hands while going out of hospital.

Abstract
ABSTRACT
Background and Objective: Anaerobic bacteria are the main cause of periodontitis. It has been shown that green tea and black tea have antibacterial effect. The aim of this study was to determine he antibacterial effect of Iranian green tea and black tea against
Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis and
Prevotella intermedia.
Methods: Aqueous and methanolic extracts of Iranian green tea and black tea at concentrations ranging from 10 to 500 mg/ml were tested against standard strains of
A. actinomycetemcomitans (ATCC 33384),
P. gingivalis (ATCC 33227) and
P. intermedia (ATCC 25671) using agar disk diffusion, broth microdilution and determination of minimum inhibitory concentration.
Results: P. gingivalis, A. actinomycetemcomitans and
P. intermedia were sensitive to the methanolic extract of Iranian green tea at concentrations of 100-500 mg/ml, 10-500 mg/ml and 50-500mg/ml, respectively.
P. gingivalis, A. actinomycetemcomitans and
P. intermedia were sensitive to the methanolic extract of Iranian black tea at concentrations of 200-500 mg/ml, 20-500 mg/ml and 200-500 mg/ml, respectively.
In addition, P. gingivalis, A. actinomycetemcomitans and
P. intermedia were sensitive to the aquatic extract of Iranian green tea at concentrations of 200-500mg/ml, 100-500 mg/ml and 200-500 mg/ml
, respectively.
Conclusion: The aquatic and alcoholic extracts of Iranian green tea and black tea have antibacterial activity against
A. actinomycetemcomitans,
P. intermedia and
P. gingivalis. Therefore, incorporation of Iranian black tea as an effective native herb could be beneficial for prevention of oral cavity diseases.
