Background and Objective: Child abuse is a common phenomenon with variety of reasons; the most important one is mother psychiatric disorders. Concurrent interventions in the family can recover the mother and reduce child abuse. This study was done to evaluate the effect of therapeutic intervention on general health of child abused mothers.Methods: This clinical trial study was conducted on 57 children and their child abused mothers whom referred to child psychiatry and pediatric department of Imam Hossien hospital, Tehran, Iran during November 2009- April 2010. Children and their families were visited by a psychiatrist and depend on the child and the family after either pharmaceutical or psychological interventions was taken. Parent management training was done for all mothers in 8 weekly sessions. General health questionnaire were filled by mothers before intervention in the third and sixth months following the intervention.Results: Total score of general health, depression and anxiety of child abused mothers were 31.3±1.90, 5.26±0.66, 8.10±0.46, respectively. It was significantly increased after six months intervention in comparison with pre-intervention (37.3±2.34, 7.48±0.72, 10.44±0.58, respectively).Conclusion: Appropriate therapeutic intervention and parent management training for mothers can improve general health of child abused mothers.

Background and Objective: Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease, leading to progressive disability, reduces daily activity and function and emerges with a wide range of physical symptoms. This study was done to determine the effect of relaxation on the physical symptoms in women with Multiple Sclerosis.Methods: In this clinical trial study, 50 patients with MS were randomly divided into relaxation and control groups. In the interventional group, Jacobson and Benson method was performed for 4 weeks, twice a week for 40 minutes and patients in the control group were received only care and routine medical treatment. Data was collected via fatigue severity scale (FSS), numerical rating scale (NRS) before, immediately after and two months after intervention.Results: The mean severity of fatigue score, before, immediately and two months after the intervention were not the same and time trends was effective on severity of fatigue score (P<0.05). The mean of fatigue score were significantly reduced in intervention group (immediately and two months after intervention) in compared to pre-intervention. The mean severity of pain score, before, immediately and two months after the intervention were not the same and time trends was effective on mean severity of pain score (P<0.05). The mean intensity of pain score over time in the relaxation group non-significantly reduced in compared to the control group.Conclusion: Relaxation technique is effective as a low-cost, safe and easy method to reduce fatigue and pain in patients with MS.

Background and Objective: Different organizers are involved in spinal cord development and differentiation by sending various messages. Specific glycoconjugates secreted from the cells of lateral wall of spinal cord can also act as neurogenesis and neural differentiation messengers. This study was carried out to determine the distribution of sugar compounds in the lateral walls of spinal cord during mice morphogenesis using lectin histochemistry method.Methods: In this experimental study, sections of BALB/c mice from 10-16 embryonic days were fixed in formalin and then histological sections were prepared. Tissue samples for reaction to the glycoconjugates were incubated with DBA, OFA, GSA1B4 and MPA lectins. Alcian blue with pH equal 2.5 was used for background staining.Results: DBA lectin did not react with the lateral wall of the spinal cord. MPA lectin showed severe reaction but consistent, especially in nerve fibers of the lateral wall of spinal cord. GSA1B4 lectin showed weak reaction in the cells and nerve fibers of the spinal cord, but severe reaction was clearly observed in blood vessels. OFA lectin showed severe reaction with a-L-Fucose terminal sugar in the lateral walls of the spinal cord in early stages of morphogenesis.Conclusion: The most reaction in the lateral walls of the spinal cord was related to OFA, which reflects the importance of fucose terminal sugar by connecting (1®6) to the penultimate sugar N-acetyl-Dglocosamin (Glc-Nac) in the development of spinal cord. Due to severe reaction of GSA1B4 to blood vessels of spinal cord, use of this lectin for vascular studies, is recommended.

Background and Objective: Rapid and adequate rehydration is important for many athletes, especially those taking multiple sessions of exercise each day, or those involved in weight category sports. The macronutrient and electrolyte concentration of the fluid ingested following exercise can affect the amount retained within the body can influence hydration status. This study was done to compare the effect of milk consumption on healthy young men rehydration and endurance performance after dehydration due to intermittent exercise in warm environmental condition.Methods: In this quasi-experimental study, the labroratory protocol was carried out by ten young healthy men in three sessions within one week intervals. Participants were on drinking regiment including water, low-fat milk, and powerade. Urine samples were collected pre-exercise, post-exercise, post-drinking and 1, 2 and 3 hours over recovery. Exercise capacity test commenced within 10 min after 3h recovery. This was undertaken in warm environmental condition at a power output corresponding to 70% VO2 max.Exercise continued until voluntary exhaustion. Heart rate and RPE were recorded at 5 min intervals throughout exercise.Results: Pre-exercise urine specific gravity value was not different between the milk and the, powerade and the water groups. Total urine output was significantly reduced in the milk group in compared to powerade and the water consumption (P<0.05). At the end of the study, net fluid balance was significantly positive in milk group compared to powerade and water groups (P<0.05). Time of exhaustion on the exercise capacity test (70% VO2 max) was significantly more in milk in comparision with powerade group (P<0.05).Conclusion: Low-fat milk is more effective at rehydrating compared to water and exercise capacity in intermittent activity of heat in healthy young men.

Background and Objective: Neonatal mortality rate is one of the most important health criteria, worldwide. Understanding the major neonatal mortality causes will help to plan for better pregnancy, prenatal and neonatal care systems. This study was conducted to determine the neonatal mortality risk factors in Maraveh Tapeh County in Golestan province, north of Iran.Methods: In this case-control study, according to either death or live in 28th day after birth, 52 neonates were considered as case group and 201 neonates were considered as control group. Data collection questionnair were adjusted and completed for each neonate.Results: Neonatal mortality rate was 11.76, 13.36 and 6.46 per 1000 live birth in 2011, 2012 and 2013, respectively. Five main causes of death were prematurity, events, birth defect, respiratory distress syndrome and sepsis, respectively. There was a significant relation between death and prematurity, birth weight and gender (P<0.05). There was relationship between birth weight and neonatal mortality (Odds Ratio=29.6).Conclusion: Prematurity and low birth weight were the most important causes of neonatal mortality in Maraveh Tapeh county in Golestan province, north of Iran.

Background and Objective: Ovarian cancer is the second most common gynecological malignancy. One of the most important genes in Wnt signaling pathway is E-cadherin (CDH1), which is involved in epithelial cell-cell interaction and plays an important role in the establishment and maintenance of intercellular adhesion, cell polarity and tissue architecture. E-cadherin codes a group of connector proteins which caused to intercellular adhesion. It has an important role in adhesion of blastomere and ability to bind fetal tissues. Nucleotide change in the coding region of this gene may lead to develop ovarian cancer. This study was conducted to evaluate the association of+54C/T (Rs1801026) 3΄UTR of E-cadherin gene polymorphism with ovarian cancer risk.Methods: This case-control study was done on 100 tissue samples of patients with ovarian cancer as cases and 100 age-matched healthy women as control in Imam Khomeini Hospital, Tehran, Iran. The E-cadherin gene polymorphism was determined by using the PCR-RFLP method.Results: There was no association between CT (95% CI: 0.81-4.31; OR=1.87; P<0.14) and TT (95% CI: 0.73-2.38; OR=1.44; P<0.29) genotypes and ovarian cancer. No association was found between genotypes with grade and stage of cancer.Conclusion: There is no correlation between+54C/T (Rs1801026) 3’UTR of E-cadherin gene polymorphism with ovarian cancer.

Background and Objective: Colorectal cancer can significantly cause physical, psychological and social problems. This study was done to determine the prevalence of anxiety and depression in patients with colorectal cancer in Babol located in north of Iran.Methods: This cross-sectional, analytical study was done on 120 (75 males, 45 females) patients with colorectal cancer which registered in the Babol cancer registry in north of Iran during 2008-12. A questionnaire containing demographic information, aspects of the disease and HADS questionnaire was completed by interviewing to assess anxiety and depression for each patient.Results: The prevalence rate of depression and anxiety in patients was 23.4% and 30.8%, respectively.Gender, residency of rural area, and having comorbidities are related to depression among which location was identified as an independent predictor. Urban residency had 79% less risk of depression than rural residents (95% CI=0.06-0.67, OR=0.21, P<0.009). Gender, resident of rural areas, unemployed, having comorbidities, low income and lack of education were associated with anxiety, among which only education was identified as an independent predictor (95% CI=1.32-13.81, OR=4.27, P<0.015).Conclusion: The prevalence of anxiety and depression in colorectal cancer patients was high in this area.Therefore, interventions are recommended to increase awareness and greater attention to rural women and controlling comorbidities.

Background and Objective: Mycoplasma Hominis is the smallest pathogenic bacteria, with no cell wall and free living organisms. It grows slowly and the conventional clinical microbiology techniques can not be applied due to difficulties in cultivation in particular slow growth incubation. This study was done to compare the culture and PCR methods for diagnosis of vaginal infection due to Mycoplasma Hominis.Methods: This laboratory test evaluation study was done on 150 patients with bacterial vaginosis and 50 healthy people with no infection as control, whom refereed to Imam Khomeini and Imam Zaman Hospitals in Tehran. Samples were collected in PPLO culture for growth and PBS to perform PCR method.Results: 35.3% and 76% of patients were positive using culture and PCR methods, respectively. Using PCR method 8% of control subjects was positive. There was no significant association between PCR method with abortion, place of residence and also level of educations. There was a significant association between the age (P<0.05), times of changing under wear cloths (P<0.05) and parity (P<0.05).Conclusion: PCR method is a more reliable technique to detect the vaginal infection due to Mycoplasma Hominis compared to culturing.

Background and Objective: Wilson’s disease (WD) is caused by mutation to the cooer-transporting gene ATP7B. Chelation therapy is the main protochol of treatment for patients with Wilson’s disease.D-penicillamine is one of the well-known chelator agants which is used in WD treatment but it can not enter into the intracellular space.This study was done to evaluate the synthesis and anti-intracellular Copper overload evaluation of Nanoconjugated D-penicillamine –Dendrimer in Wilson’s model cells.Methods: In this descriptive-analytic study, initially 0.01 mm polyethylene glycol (PEG) and 0.0018 mm citric acid, Dendrimer was synthesized.

After incubation and centrifugation intracellular measurement of copper concentration and FTIR test were done.Results: Copper accumulation significantly reduced in the HepG2 WD cell by Nanoconjugated D-penicillamine - Dendrimer in compared to D-penicillamine (P<0.05). Copper accumulation was determined to be 46.61. MTT assay showed no toxicological damage in HepG2 WD cell.Conclusion: Nanoconjugated D-penicillamine –Dendrimer can reduces intracellular concentration of Copper.

Background and Objective: Wound infection treatment, particularly in chronic and bacterial poly cases, is difficult and entails heavy costs. This study was done to determine the prevalence of poly bacterial infection and antimicrobial susceptibility of wound samples from different wards.Methods: In this descriptive study, wound sampling was prepared from 336 patients admitted to different wards of Baqiatallah Hospital in Tehran, Iran. Identification was performed based on biochemical tests including oxidase test, TSI, IMVIC, lysine decarboxylase, phenylalanine deaminase, urea, motility, catalase, coagulase, mannitol fermentation, optochin sensitivity, susceptibility to bacitracin and sulfamethoxazole, growth in Bile esculin and DNase production. Antibiotic resistance pattern of isolates was determined using disk diffusion method for 14 important antibiotics.Results: 294 samples were positive for bacterial culture, from which 364 isolates including 11 different isolates were obtained. Out of 294 positive samples, 245 samples were mono bacterial and 54 were poly bacterial including two-bacterial (45 samples), three-bacterial (7 samples), and four-bacteral (2 samples).S. aureus (29.7%), Enterococci (15.6%), and E. coli (15.6%) were the most prevalent isolates. S. aureus- Enterococci pattern was the most common two-bacterial pattern (33%), and majority of polybacterial patterns belonging to gram negative bacteria was in surgery ward (32.5%). Antibiogram results showed high levels of antibiotic resistance in the isolates. Imipenem and amikacin were the most effective antibiotics against Gram negative isolates, and vancomycin for Gram positive isolates. Also, 71% of S. aureus isolates were resistant to oxacillin.Conclusion: Variation of bacterial isolates was similar to other studies. Most of poly-bacterial wound infections were due to common nosocomial pathogens and their high rates of antibiotic resistance are extremely alarming.
