Abstract
Abstract Background and objectives: In diabetic patients, infectious disease is one of the most important cause of admission, and sometimes a life threatening condition. The aim of this study was to determine the clinical features of infection in the hospitalized diabetic patients. Material and Methods: In This retrospective study, we evaluated the files of 122 diabetic patients aged over 20 years in 2004-2005. According to medical document coding, the data was collected by a checklist and then descriptive statistical analysis performed. Results: The subjects’ age is 57+11.76 years (23-83). The Mean time of diabetes diagnosis is 12.62+9.27 years. Sixty-six of them are male (54.5%).and the rest female. most of them (62.2%) were used oral hypoglycemic drugs on admission. Their median fasting blood sugar was 224mg/dl and 164mg/dl for the first and second measuring, respectively. The etiologies are soft tissue infection and diabetic foot ( 49.3%), sepsis(36%),pneumonia(5.7%),urinary infection(3.2%) and unknown(5.7%). None of diabetic foot patients was given specific education for taking care of their feet. Conclusion: in sixty -five percent of the subjects, fasting blood sugar was not in normal limit. Soft tissue infection and diabetic foot was the most infectious cause of admission. It seems that frequent control of blood sugar and foot- care related education can prevent from the most common cause of hospital admission in these patients.

Abstract
Background and objectives: ABO phenotyping is one of the essential tests in Immunohematology. Incompatible blood group transfusion leads to acute hemolysis reactions and other serious complications. Anti A1 is a cold Antibody with no clinical significance, but if it is reacted at 37˚c can be clinically significant, which will be happened rarely. At the present, we report a Case with anti A1 having clinical significance and Anti C.
Material and methods: The patient was suffering from Paroxysmal nocturnal hemoglobinuria (PNH) and received repeated blood transfusion. The tests performed for this patient were blood grouping, Antibody screening, panel test and cross match.
Result: the patient’s blood group is AB (A2B) with anti A1. The presence of anti C is verified by applying Panel test.
Conclusion: to prepare appropriate blood, Cross mach test was performed on A2B blood bags without C Antigen. During laboratory tests and blood transfusion, no reaction was observed. This report indicates that being aware of anti-antigen antibodies is an important point.
Key words: Anti C and Anti A1 with Clinical importance, PNH, Ab Screening

Abstract
Abstract Background and Objective: Vancomycin is used for treatment of methicillin-resistant S. Aureus (MRSA) infections therefore, resistance to this antibiotic is increasing. We aimed to determine the antibiotic resistance pattern and frequency of vancomycin resistant S. Areas (VRSA) strains isolated from clinical samples. Material and Methods: In this cross-sectional study, 100 S. Aureus isolates collected from hospitals in Shiraz during six months, 2012, were identified by biochemical, microbiological and molecular methods. After determination of antibiotic susceptibility pattern by disc diffusion method and vancomycin agar screening test, Minimum Inhibitory Concentration (MIC) was determined by E-test for vancomycin, thicoplanin, linezolid and quinupristin-dalfopristin. Results: The most resistant and the most sensitive antibiotic were ampicillin (%95) and quinupristin-dalfopristin (99%), respectively, and 44% of isolates were resistant to methicillin. In agar screening test, 48% of strains had reduced sensitivity and in disc diffusion 3% strains were resistant to vancomycin. In E-test method, only one isolate was resistant to vancomycin. Conclusion: given the presence of VRSA and new antibiotic resistant strains, we recommend doing some intervention to prevent from spreading these strains in hospitals. .

Abstract
Background and Objective: Biological weapons, like other weapons of mass destruction such as chemical, nuclear and radiological are very dangerous. In recent years, they are employed in biotterrorist attacks by many countries because of some properties such as: the ability to make massive injury, having latent period, creating a prolonged illness, potential outbreaks and epidemics and more important because of having nonspecific symptoms and difficulty in diagnosing.
Material and Methods: The objective of this study was to describe the role of microbiology laboratories and their experts in the interventions of bio-passive defense. In this study, we use CDC, Medline, Google Scholar, Pubmed and World Health Organization (WHO).
Result: Detection of biological agents is difficult and sometimes impossible due to features such as lack of odor, color and other physical characteristics. The most important measures for defense against biological agents are rapid detection and intervention. Thus, the laboratories should highly be equipped and the personnel be extremely sophisticated to deal with the crisis.
Conclusion: Regarding the presence of highly advanced molecular procedures, Microbiology laboratories have to be updated to deal with the potential threats .in addition, the Laboratories professionals must be trained for the latest guidelines and specific diagnostic techniques to work with biological agents.

Abstract
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.

Abstract
Background and objectives: The hoteling quality promotion is part of the health system development plan, based on which the physical appearance of laboratories of public hospitals are improved and renovated. The present study aimed to evaluate the policy-making gap in the hoteling quality promotion of the health system development plan in providing laboratory services in public hospitals in the Golestan Province, Iran.
Methods: This descriptive-analytical and cross-sectional study was performed on 384 medical staff and physicians working in laboratories of public hospitals affiliated with the Golestan University of Medical Sciences, Golestan Province, Iran. Data were collected using a 35-item researcher-made questionnaire that was distributed and collected over a period of six months. We examined the extent of the gap between the current and expected status based on the two components: the alignment of key stakeholders with health system development policies and stakeholders' opposition to health system development policies, as well as the extent of the gap
Results: The hoteling quality promotion was about -0.05 in providing laboratory services in public hospitals of the Golestan Province, indicating a low gap between the current and favorable status in the fifth axis of the health system development plan in terms of supervision.
Conclusion: The implementation of the hoteling quality promotion plan in providing laboratory services in public hospitals of the province is not consistent with the expected goals of the fifth axis of the health system development plan. Therefore, there is a need to examine and eliminate effective factors contributing to this gap.

Abstract
Background: Although the anti-diabetic effects of various Ficus species have been investigated in animal models, research on the blood glucose-lowering potentials of Ficus lacor Buch Ham bark remains sparse. This study evaluated the blood glucose-lowering potentials of an aqueous extract derived from Ficus labor bark in a diabetic rabbit model.
Methods: Diabetes was induced in rabbits through intravenous administration of alloxan monohydrate (120 mg/kg). 36 rabbits were divided into six groups, each consisting of six animals. Control groups included a non-diabetic control (Distilled water) and a diabetic control (Distilled water). Two experimental groups received Ficus lacor extract at doses of 100 mg/kg (Low-dose) and 200 mg/kg (High-dose) orally for six weeks. Metformin was used as an active control. A non-diabetic group (Extract control) was also administered Ficus lacor extract at 200 mg/kg. Fasting blood sugar (FBS) and post-prandial blood sugar (PP2BS) levels were measured weekly over the 6 weeks. The percentage reduction in blood glucose levels was calculated and compared for each group.
Results: The administration of both low-dose and high-dose Ficus lacor extracts resulted in significant reductions in FBS and PP2BS levels in diabetic rabbits. After six weeks, the low-dose extract group exhibited an average reduction of 38.3% in FBS and 40.5% in PP2BS, whereas the high-dose extract group showed average reductions of 35.3% in FBS and 36.3% in PP2BS.
Conclusion: The aqueous extract of Ficus lacor bark demonstrates substantial glucose-lowering activity, indicating its potential utility as a therapeutic agent in diabetes management.

Abstract
Hairy cell leukemia (HCL) is characterized by pancytopenia and usually associated with massive splenomegaly, however the same may not be true in the clinical settings. Here we report a case of HCL without the classical clinical feature of splenomegaly. Absence of splenomegaly doesn’t exclude he diagnosis of HCL. A careful study of morphological findings on bone marrow aspirate and biopsy followed by appropriate ancillary tests aids in correct diagnosis. A high index of suspicion is essential for diagnosing and appropriately
managing such cases. A strong suspicion on morphology in such cases is a prerequisite for reaching onto a correct diagnosis , even in absence of usual clinical presentation.
