Introduction: Plantar fasciitis is one of the common complications in adults. It can be treated by surgical and nonsurgical interventions. Nonsurgical treatments (functional foot orthosis, heel pad, night splint and wedge) are emphasized as the main option in management of plantar fasciitis. Wedge can be used effectively because of its low weight, low price, easy making and availability to the patient. In this study the effect of medial heel wedge on managing pain in patients suffering from plantar fasciitis was examined. Materials and Methods: In this before and after clinical trial, 15 patients with plantar fasciitis including 6 male and 9 female with 18 involved extremities were selected by non probability sampling.Variables including pain, ADL, sport and recreational activity, quality of life, stride length and step length were measured in three stages: once before intervention and then two and four weeks after intervension. For evaluating the variables, FAOS questionnaire was used. Data was analyzed using ANOVA. Results: The improvement of variables such as pain, ADL, quality of life, sport and recreational activity, step length and stride length was significant (p=0.05). Conclusion: Medial heel wedge reduced pain by shifing the center of force into lateral border of heel in addition to reduce the tension of plantar fascia.

Introduction: About 21 millions low birth weight infants are born throughout the world and have less surviving chance compared to death rate of infants due to other causes. The aim of this study is to determine the relation of mothers' nutrient intake in the last trimester with the delivery of low birth weight infants. Materials and Methods: This Cohort study with a 3-months follow up was carried out on all the pregnant mothers visiting health care centers in Shahrood during their third trimester. Simple sampling was done and samples included 424 subjects. One-week food record of subjects was documented biochemical and hematological tests and also anthropometric examinations were done, and demographic data were gathered. The infants’ birth weight was measured after delivery. Data was gathered by a questionnaire and analyzed using Chi square, Mann-Whitney and Leven tests and logistic regression. Results: Total number of 424 pregnant mothers was studied in accordance with their amount of energy and protein intakes, and was classified in two groups of adequate and inadequate status. It was disclosed that 75% of mothers received low energy (less than 2500 k cal) and 20% were low in protein intake (less than 60gr). Low birth weight prevalence was detected to be 13%. Among low birth weight infants 14%, 25% and 43% were attributed to mothers with low energy, low protein, and non-iron tablets intake respectively. There was a significant relationship between birth weight and iron supplementation (P=0.015), as well as multi-vitamins (P=0.048) during the last trimester of pregnancy. It was also disclosed that the probability of low birth weight infants among low weight mothers was 86%. Conclusion: According to the results there is a significant relationship between mother's nutritional status in the last trimester of pregnancy and infant's birth weight, so it is recommended that mother's weight gain especially in the third trimester and using adequate supplementations be considered.

Introduction: Diabetes mellitus is a chronic disease that has well known effects on most organs, but there have been controversies in few different studies about the effects of diabetes on hearing. So this study was carried out in 2003-2004 in Kermanshah Diabetes Research Center to assess the effect of diabetes on hearing. Materials and Methods: This is a case-control study. 82 diabetic cases (26 types I and 56 type 2 cases) were studied along with 82 controls matched both in age and sex. Cases were selected randomly, their range of age was 15 to 55 years and their duration of diabetes was more than 3 years. After completing questionnaires, all cases and controls undergone autoscopic examination. Those with other ear disease with hearing impairment were omitted. Audiometery including pure tone audiometery, speech audiometery, and impedance audiometrey with well tone AD19 formed was done on 164 (diabetic and control) persons. Data was analyzed using t-test. Results: Audiometric findings with different frequencies in the two groups revealed that there was a significant relationship between diabetes and hearing impairment (p<0.001). This relationship was more significant in high frequencie, older age and type 2 diabetes, but there were no relationship between control of blood sugar (HbA1c), duration of diabetes, sex, microvascular and macrovasculur complications with hearing loss in diabetic patients. Conclusion: These finding demonstrate that diabetes can cause mild to moderate hearing impairment especially in high frequencies. The mechanism of this effect is unknown. Complementary studies with more patients and with more accurate devices such as Otoacustic Emission (OAE) and Audiometric Brainstem Reflex (ABR) are recommended

Abstract Background: Information on patients' physical and mental disabilities, their lifestyle during rehabilitation period and probably their death due to severe head injury in acute phases is too insufficient and in some cases, it does not exist at all. The aim of this study is to determine the outcome of patients who were hospitalized in Vali-asr Hospital of Arak according to Glascow Coma Scale (GOS). Materials and Methods: In this cross-sectional retrospective study, using the patients' files in Vali-asr Hospital which is situated in Arak, the patients, who had been hospitalized with severe head injury during 2005-06, were identified. Based on the information existing in their files or visiting them individually in their place of living, 24 months after their release from hospital, their physical and mental performances were examined according to Glascow Outcome Scale (GOS) and were compared to the time of their release from the hospital. Results: Out of 130 patients, 55.4% died within 2 years after the hospitalization period. Among those dead, 32% died in the first 24 hours of hospitalization, 44.4% after the first 24 hours and before release from the hospital and 23.6% after being released from the hospital. The mean of GOS score, from the time of release until 2 years after that, improved from 2.7 to 3.3. Conclusion: Noticing the fact that more than half of the patients died after getting to hospital either in acute level or during rehabilitation, the need is felt for making revisions in the programs for taking care of these patients in different phases of treatment

This study considers the art of Quran in healing human psychological and spiritual disorders. Since the subject matter of Quran and medicine is human and the objective of both is health and welfare of human body and soul, it is suggested that man can learn how to remedy his psychological pains through Quran. Accordingly, after providing definitions for sick and healthy heart and soul, we will look at some instances of psychiatric disorders and investigate them closely through ideas put forward by scientists. Also, we argue that the origin of these diseases goes back to human motivations, belief system, and social and political matters, while some are related to ethical principles. Then we will focus on the qualities and effects of healthy soul in the view of Quranic verses. Eventually, it will be stated that since human behavioral reactions are the signs of a healthy soul or a psychotic one, those who seek peace in this world and salvation in the afterworld are suggested to prevent and cure psychological problems and create balance in their personality by using commandments given by Quran since the aim of Quran is maintaining balance between different instincts.

Background: Today, there is growing interest in using traditional medicine for healing cutaneous wounds. Probiotics are defined as different microorganisms that may have positive effects on prevention or treatment of special pathologic conditions. The present study was designed to investigate the effect of Lactobacillus brevis on cutaneous wound healing. Material and Methods: In this experimental study, through phenol-sulfuric acid method, 22 strains of lactobacillus isolated from dairy-traditional products were investigated in terms of exopolysaccharide production. Lactobacillus brevis, which had high exopolysaccharide (EPS) production, was selected. A wound was created on the back of male Wistar rats in control, negative control, and experimental groups. Control and experimental groups underwent regional treatment by eucerin and eucerin contained Lactobacillus brevis, respectively, but the negative-control group did not receive any treatment. On days 1, 7 and 21, the rats were killed and their cutaneous wound samples were studied. Data analysis was done through SPSS version 11.5. Results: The percentage of wound healing (99.53%) and inflammation in the experimental group on day 21 compared to control (90.55%) and negative groups (91.14%) was significantly higher (P<0.001). The number of neutrophils in the experimental group decreased in later phases of wound healing compared to the control and negative control groups. Conclusion: The present study showed that Lactobacillus brevis significantly decreases inflammation and accelerates wound healing in treated rats. The findings of this study can be applied clinically in near future

Background: The major aim of this study was synthesis and assay of antimicrobial activity of peptide D28 and its new analogues derivatives as dimeric peptides. Materials and Methods: Three antimicrobial peptides known as D28, Di-D28-Lys,Di-Cys-D28 including 20, 41, 42 residues were synthesized respectively. For peptide synthesis, solid phase peptide synthesis method using blocked amino acids with flourenyl methoxy carbonyl group and for peptide purification HPLC were used. Peptides compositions were confirmed by amino acid analysis and SDS-PAGE electrophoresis. Antimicrobial tests against Staphylococcus aureus and Pseudomonas aeruginosa were performed as disk and well diffusion on plate and by adding to liquid broth culture (Broth macrodilution) in different concentrations. Results: Three required peptides (D28, Di-D28-Lys, Di-Cys-D28) successfully were synthesized. All three peptides were effective against S. aureus, but Di-Cys-D28 on the contrary to two other ones, showed no antimicrobial activity against P. aeruginosa. The inhibitory activity of Di-D28-Lys against P. aeruginosa was more than that of D28 peptide. Conclusion: Improvement of antimicrobial peptides activity through dimerization depends on the methods of dimerization and the strain of bacterium. Di-D28-Lys peptide in comparison with D28 and Di-Cys-D28 showed wide range and more antimicrobial activity. Therefore, Di-D28-Lys peptide could be a suitable antibiotic candidate for future studies.

Background: Enterotoxigenic Escherichia coli bacterium is the most important bacterial agent causing diarrhea. Specific virulence factors, such as enterotoxins and colonization factors, distinguish ETEC from other classes of diarrheagenic E.coli. In this study, heat-labile toxin was purified which could be utilized for anti-toxin assay in GM1 gangelioside receptor-ELISA based method and for identification of ETEC producing toxin. Materials and Methods: In this experimental study, bacterial strain producing heat-labile toxin was first cultivated for production and purification of toxin. Then supernatant soluble proteins were precipitated with ammonium sulfate and purified using biochemical methods. Finally, purified protein was dialyzed against Tris 0.02 mM pH 8 and analyzed on gel electrophoresis. GM1 gangelioside receptor-ELISA based method was used for detection and assessment of the purified toxin. Through this method, the effect of anti-recombinant heat-labile toxin B subunit neutralization on heat-labile toxin was investigated. Results: Toxin purification was revealed by the presence of 12 and 28 KD protein bands. This study demonstrated that anti-recombinant heat-labile toxin B subunit antibody can detect the purified toxin and can inhibit its binding to GM1 receptor up to 80%. Conclusion: Purification of heat-labile toxin and gangelioside receptor-ELISA assay can be used for accurate detection and epidemiological study of clinical isolates.

Background: One of the most important complications of tonsillectomy is laryngospasm which leads to airway obstruction, arterial hypoxemia, and hypercarbia. Thus the present study was carried out to compare the effect of propofol with sodium thiopental, as an induction agent of anesthesia, on the incidence and intensity of laryngospasm after extubation in tonsillectomy. Materials and Methods: This double-blind clinical trial was done on 60 3-12-year-old patients who were chosen for elective tonsillectomy at Qods Hospital in Qazvin. The patients were randomly divided into two equal groups. Method of anesthesia was the same in these two groups except for the induction of anesthesia one group received sodium thiopental and the other group received propofol. At the end of the operation, patients were extubated after the restoration of spontaneous respiration with adequate tidal volume and respiratory rate. Then the incidence and intensity of laryngospasm was evaluated. Data were analyzed by t-test, Chi-square, and Fisher's exact test using SPSS software. Results: Overall, 83% of the patients in the sodium thiopental group and 93% of the patients in the propofol group did not develop laryngospasm and there were no statistical differences between the two groups in terms of the incidence and intensity of laryngospasm after extubation in tonsillectomy (P=0.535). Conclusion: As an induction agent in general anesthesia, propofol has the same effect as sodium thiopental on the incidence and intensity of laryngospasm after tonsillectomy.

Background: Deaths due to cancer have been increasing in many countries in recent years. Probiotics are live microorganisms that have beneficial effects on consumer’s health. The aim of this study was to investigate antimutagenic and anticancer effects of Lactobacilli strains isolated from Tarkhineh in order to select potential probiotic strains. Materials and Methods: In this experimental study, 25 strains of Lactobacillus that had previously been isolated from Tarkhineh were used. Antimutagenicity test was performed based on proposed method of Ames. The results of the test were individuated after comparison between samples (suspensions of Lactobacilli) and positive (sodium azide) and negative (distilled water) controls. SPSS version 16 was used for statistical analysis. Results: Antimutagenic activity was observed only in four strains of Lactobacilli. The inhibitory percentage in the four strains of Lactobacilli, in its highest level was equal to 60.38 and in its lowest percentage equal to 39.37%. Also, the inhibitory percentage of mutation among the four strains in the presence of microsome were significantly different (P<0.05) than the absence of microsome. Adding the microsome of rat liver (S9) proved the anticancer effects of four Lactobacilli strains. Conclusion: Of the 25 strains of Lactobacilli, 4 strains which had the highest antimutagenicity effects were chosen as the potential probiotic strains.
