Abstract
The present research is a cross-sectional study which was done in Vali-Asr hospital in the b first nine months of 1378. The highest percent of infection was observed in surgery ICU with 34.6% (p<0.05) and the infection rate was higher in the women than the men. Staphilococcus Areus, with 41.1% incidence, has been the most common microorganism. In fact gram positive bacteria are the cause of nosocomial infections.

Abstract
Introduction: There is little information about essence and combination of ductuli efferentes secretions. Glycoconjugates importance in sperm production and maturation has been confirmed in previous studies therefore this study is done in order to recognitize Glycoconjugates in ductuli efferentes epithelium and determination of their distribution pattern by means of lectin histochemistry. Materials and Methods: In this descriptive study tissue species were obtained from 30 adult male BALB/c mice. After fixation and routine laboratory processes, 5 μm sections were prepared from paraffin blocks. These slides were exposed to different lectins by means of lectin histochemistry. Reaction intensity in different cells was investigated by light microscope and graded according to the previous related studies. Then results were compared with each other by Kruskal-Wallis and Dunn statistical tests. Results: The mean of reaction intensity in ductuli efferentes epithelium in reply to different lectins, showed significant statistical difference (p<0.005). The most intense reaction was seen in response to WGA (Wheat Germ Agglutinin) lectin and after that to SBA (Soybean Agglutinin), VVA (Vicia Villosa Agglutinin) and PNA (Peanut Agglutinin) respectively. But the staining was negative with GSA-I (Griffonia Simplicifolia Agglutinin-I) lectin. Conclusion: Results indicate that the cells of ductuli efferentes epithelium in mouse are involved in synthesis and secretion of sperm maturation related glycoconjugates and produce a variety of these components in various amounts. There is a large amount of components, containing terminal sugars such as Sialic acid,Galactose-N-Acetylgalactosamine and N-Acetylgalactosamine in ductuli efferentes cells. The lack of Galactose in this epithelium shows that, it hasn’t a role in sperm maturation.

Abstract
Background: The effectivity of applying antiseptics in preparation of the operative site on the reduction of post-operative infections is not quite clear and controversies exist about the best method for doing this. The aim of this study is to compare the traditional two-stage method of first, washing the site with povidone iodine scrub and then painting with aqueous povidone iodine with the method of washing the site only with povidone iodine scrub. Materials and Methods: In this retrospective study, patients who had been under knee arthroscopy in 2 separate hospitals by the same surgeon were compared with regard to post operative infection. In one hospital, the operative site was only washed with povidone iodine scrub, while in the other hospital this same procedure was followed by painting with aqueous povidone iodine. The primary goal of this study was to identify the patients who had manifested clinical and laboratory signs of superficial or deep infection or septic arthritis one month postoperatively. Results: A total 300 patients were studied in two equal groups. All the patients had only been under diagnostic or curative non-bony operations. No superficial or deep infection or septic arthritis were seen in any of the patients in the two groups. Conclusion: Preoperative preparation of the knee with povidone iodine scrub is a safe method for prevention of infection and can be used instead of the common two-stage method of using povidone iodine scrub and then painting with aqueous povidone iodine since this can decrease the time and cost of surgery.

Abstract
Background: Candida species are the most common yeasts that reside in oral cavity in 30 - 50% of people, and are capable to produce opportunistic infections within the oral cavity. This study was done to determine the effect of cigarette smoking on the type and degree of Candida oral carriage.
Materials and Methods: In this case-control study, oral Candida flora in 34 smoker and 66 non-smoker men were compared. All of the samples were collected by swab and examined by direct microscopy and culture on CHOROM agar Candida and corn meal agar media. Isolated colonies were identified by carbohydrate assimilation method using RapID Yeast PLUS System.
Results: Out of the 34 smoker individuals, 27(79.4%) had Candida colonization in their oral cavity while 30(45.5%) of the 66 non-smoker individuals had developed this kind of colonization. A significant difference was observed between the two groups (p<0.05). Additionally, there was a significant difference in the degree of colonisation and the type of candida species which were isolated from the oral cavity of the smoker and nonsmoker groups.
Conclusion: Cigarette smoking can act as an important underlying factor in oral candidiasis.

Abstract
Background: In recent years, changes in the composition of Iranian population into aged population have increased the need for more information about the quality of life (QOL) of this group. Proper planning for this age group for increasing their quality of life depends on the identification of factors associated with QOL. The aim of the current study was to assess the quality of life and its relationship with the quality of diet in elderly people aged 60 years and more living in the urban areas of Markazi province. Materials and Methods: This cross-sectional study was carried out on 165 elderly people in the urban areas of Markazi Province in 2010. Data obtained via general and QOL (SF-36) questionnaires and three 24-hour recalls on food. The quality of diet was measured using Healthy Eating index. Results: The means of total SF-36, physical and mental components scores were 55.66, 51.32 and 57.30, respectively. Additionally, the average overall healthy eating index score was 82.83. The results showed that the total, physical, and mental components of SF-36 scores in the elderly were positively associated with the healthy eating index but not significantly (P=0.2). QOL and diet scores were significantly associated with age, sex, education, previous employment, income, leisure activities, exercise, insurance, smoking, present disease, and drug consumption (P<0.05). Conclusion: The results showed that the QOL in the elderly was not related to their quality of diet.

Abstract
Background: Ventilator-associated pneumonia (VAP) is one of the most important causes of mortality in intubated traumatic patients admitted in ICU. The aim of current study was to determine correlation between blood products transfusion with incidence of VAP in traumatic patients under mechanical ventilation in ICU.
Materials and Methods: This study was a prospective descriptive-analytical study. Current study was carried out on traumatic patients under mechanical ventilation admitted to Imam Khomeini hospital ICU wards of Sari city, from September 2015 to September 2016. In addition to demographic data, patients' clinical information were daily recorded.
Results: Of total of 2304 patients admitted to ICU, 186 traumatic patients under mechanical ventilation longer than 48 hours were reviewed and analyzed. Among patients infected with VAP, 36 persons(87.8%) had transfusion of blood products before VAP incidence. Blood products transfusion (before and / or after 48 hours) had the highest adjusted risk ratio in the incidence of VAP (Odds ratio; OR=3.58). Also, amount of injected Packed Red Blood Cells and platelet were significantly higher in patients infected with VAP (p<0.005).
Conclusion: Considering remarkable increase in incidence of VAP following blood products transfusion and its correlation with injected PRBC and platelet, considering these modifiable risk factors for controlling and preventing the incidence of VAP in traumatic patients under mechanical ventilation in ICU is necessary and reasonable.

Abstract
Background and Aim: In patients suffer from Polycystic Ovary Syndrome (PCOS), the secretion of the Luteinizing Hormone (LH) increases while adiponectin secretion and dopamine release decreases. Dopamine and adiponectin exert inhibitory effecs on LH secretion. In the present study the effects of L-dopa and dopamine receptor antagonists were investigated on LH secretion and adiponectin gene expression of in PCOS model rats to determine whether dopaminergic pathway might be involved in the decreasing LH via affecting adiponectin.
Methods & Materials: Following estradiol valerate- induced PCOS, fifteen PCOS rats were divided into 3 groups including saline receiving group, L-dopa(100 mg/kg) or simultaneous injections of sulpride(10 mg/kg), SCH23390 hydrochloride (1 mg/kg) and L-dopa(100 mg/kg), Five intact rats received saline as negative control group. Blood samples were collected via tail vein. Ovary and hypothalamus were dissected and frozen. Serum concentration of LH and relative gene expression of adiponectin in ovary and hypothalamus were determined by radioimmunoassay and real time-PCR method.
Ethical Considerations: This study was approved by the Research Committee of University of Mohaghegh Ardabili (Code: 95.125.1).
Results: Induction of PCOS caused a significant increase in mean serum concentration of LH and a significant decrease in mean relative gene expression of ovarian and hypothalamic adiponectin compared to control group. L-dopa caused a significant decrease in serum concentration of LH, a significant decrease in hypothalamic gene expression of adiponectin compared to PCOS rats. But it did not significantly increase ovarian adiponectin gene expression in comparison to PCOS rats. Dopamine receptor antagonists inhibit the effects of L-dopa on LH and hypothalamic gene expression of adiponectin.
Conclusion: Dopaminergic signaling pathway may be involved in decreasing LH secretion via increasing hypothalamic adiponectin gene expression level in PCOS rats.
