Introduction: Sensory stimulation of comatos patients is an important nursing intervention for increasing their LOC and tactile stimulation especially massage is one of the most important stimulations. The nurse as a person, who is responsible for this, must know the effects of this intervention on patients. But there are some conflicts about this intervention's effects especially on vital signs (pulse, blood pressure and respiration). This study was done to determine the effect of massage on comatos patient's vital signs who were hospitalized in intensive care unit. Materials and Methods: This study is a clinical trial. Samples were consisted of 100 comatos patients, divided into two equal groups randomly. The two groups were matched in age, geneder and glascow coma scale. Samples in experimental group received 20 minutes massage on their back, feet and hands in three continuous days. Vital signs in experimental group were measured before and immediately after intervention and vital signs in control group were measured at the same time with experimental group. A check list used was used for collecting data. Data was analyzed using descriptive and analytic statistics (T, paired T and Chi-square tests). Results: Findings showed that massage decreased vital signs significantly as followed: pulse rate and diastolic blood pressure in each three days (p<0.05), systolic blood pressure in first and third days (p<0.05), respiration rate in second day (p<0.05). Conclusion: This study showed that massage can decrease comatos patients' vital signs which can be the indicator of their relaxation and decreasing stress.

Introduction: End stage renal disease (ESRD) is a major health problem and each year the number of patients is increasing. If the disease becomes irreversible, patients must always be hemodialyzed. Since mortality rate will increase due to inadequate dialysis, determining the efficacy of hemodialysis and improving its quality is very important. The main goal of this research is investigating the efficiency of hemodialysis. Materials and Methods: This is a cross-sectional analytical study which was conducted on 103 people who were under dialysis treatment in the Vali-e-Asr hospital of Arak in year 2003. Weight, blood pressure (before and after dialyze), time of dialysis, BUN and Cr before dialysis and 5 minutes after turning of the pump and before the second dialysis were measured. Data was analyzed by T test and Pearson correlation. Results: The mean of KT/V was 0.58 ± 0.1 normal protein catabolic rate (nPCR), 0.36 ± 0.11 g/kg per day and time average concentration of urea (TAC), 43.3 ± 14 mg/d which had a significant difference with standard measures (p<0.05). KT/V was 0.49 ± 0.18 and 0.47 ± 0.10 for men and women respectively which was significantly different (p<0.03). There was a positive and linear relationship between education level and TAC, KT/V and number of dialysis per week. Conclusion: Regarding the low efficiency of hemodialysis in 80% of patients and lower levels of hemodialysis efficacy indicators in comparison to standard measures, periodic assessment and also investigating the reasons of low efficacy of hemodialysis is recommended.

Introduction: Menopause is a natural period of life. It means the permanent cessation of menstruation and the end of reproductive period which occurs between 45-52 years old. It also serves as an indicator of population health as the occurrence of menopause indicates the increased risk for the onset of several chronic diseases. In this study, the mean age of natural menopause among women in Arak (Central Iran) was investigated, considering their reproductive and socio-economic-demographic factors and their health behaviors. Materials and Methods: This study was an observational cross-sectional study on a population base, carried out in 2007 year. Interviews and questionnaires were used for gathering data from 458 women resident in Arak city, who had undergone a natural menopause. Sampling was multistaged using postal zones and selecting samples in each zone. Data was analyzed using variance analysis, multiple regression, T and correlation coefficient tests. Results: Findings showed that the mean age of menopause in our sample was 48.2±2.34 years (95% CI: 47.98- 48.41) and its median was 49 years. The mean age of menopause in women who were never married was less than married women (P= 0.015). Low income level (P= 0.003), having physical activity (P= 0.004), number of pregnancies (P<0.001), age of last pregnancy (P=0.026) and place of birth (P=0.003) were meaningfull factors in age of menopause. Conclusion: This phenomenon must be documented in Iran because of its strong link with mortality and morbidity of the growing number of women who are reaching advanced ages whose one forth of life is after menopause. Therefore health education as the best way for changing their lifestyle is suggested.

Introduction: In this study, antimutagenesis effect of ethanolic extract of propolis by Ames test against two mutagenic substances named azide sodium and potassium permanganate in the presence and the absence of microsomal homogenate of mouse liver (S9) has been investigated. Materials and Methods: In this experimental study at first, different concentrations of ethanolic extract of propolis (0.1-5%) for determining minimum inhibitory concentration (MIC) against tester strains were used. Then by Ames test, antimutagenesis effect was assessed in nontoxic extent. In this test, various strains of Salmonella typhymurium (TA100 and TA97) that contained selective mutation in their operon histidine, were used. Mutant strains (His-) were grown on culture media containing minimum salt and glucose in the presence of mutagen substances above. So only those bacteria that were reversed by mutation (His+) could grow and form colonies on culture media. If antimutagen (EEP) and mutagen substances were gathered, reversed mutation would be reduced and the rate of mutation inhibition could be calculated by means of formula. The differences between the averages of revertants per plate of the sample in relation to the mutagens were analyzed using SPSS software and one-way ANOVA. Results: The resulted MIC values clearly showed that ethanolic extract of propolis at 5% concentration has antibacterial activity against Salmonella typhymurium, but in 0.1-4% concentrations, such effects were not seen. Findings also showed that propolis in such concentrations could neutralize mutagenic effects of those substances in a dose dependent manner. Conclusion: Finally we found that ethanolic extract of propolis that contains different kinds of major and important substances like flavonoids, has good antimutagenic effects and the best concentration for obtaining such effect is in 4% which also was confirmed with microsomal results. The mechanism of antibacterial effect of propolis is complex and it has no analogy to any classic antibiotics, but it should be emphasized that bacterial cell division is inhibited by propolis. Some researchers also argue that propolis could inhibit DNA-dependent RNA polymerase.

Background: Labor pain, which is a natural, unique and multi- factorial pain, is considereds a major part of women's anxiety at reproductive ages. There are two pharmacological and non-pharmacological approaches for reducing this pain. Since the pharmacological approach involves side effects, lots of attention has recently been given to the non-pharmacological methods. One of these methods, is use inc birth ball the, which includes sitting and rocking on the birth ball. The purpose of this study was to evaluate the effects of using birth ball on labor pain, the duration of active phase and contractions of physiologic labor. Materials and Methods: In this randomized control-clinical trial, sixty primiparous women (18-35 year old) were selected and randomly assighed into birth ball and control groups. The severity of pain was measured through Visual Analogue Scale (VAS) and the pain score, interval between contractions and duration of active phase were compared between the two groups. Results: The average pain score in the birth ball group was significantly lower than the control group (p<0.05). In terms of interval between the contractions, duration of active phase and uterine contractions, there were no significant differences between the two groups. Conclusion: Although use of birth ball did not have any effects on the duration of active phase, uterine contractions and interval between uterine contractions, this complementary therapy reduced the severity of pain during the active phase of delivery. Therefore, this safe method is suggested to be used during normal vaginal delivery and physiologic labor. Also, conducting a study, which examines the effects of using a combination of complementary methods, is recommended

Background: Eating and drinking according to health instructions is a major factor in health. Islam recommendations regarding nutrition ensure not only physical health but also mental health. While advising Muslims to consume meat as much as their body requires, Islam forbids certain types of meat. This study is to investigate the effect of pork consumption on human health from the perspective of Quran and medicine. Materials and Methods: Relevant Quranic verses and Hadith and the existing literature were reviewed and described through the use of specific keywords. We utilized relevant materials from the Holy Quran and Hadith and also conducted a literature search through specific related keywords. Results: In four Surahs of Quran and Hadith from the infallible Imams, pork consumption is forbidden. The presence of a group of amines, carcinogenic agents, high fat, and a high level of growth hormones turns pork into a sutoxin product. In addition, the presence of significant zoonotic diseases, quick decay, and easy contamination are other reasons which make pork consumption harmful for human. Conclusion: Noticing the significant role of nutrition in physical and mental health, divine religions have pronounced recommendations on using decent and healthy nutrition and refraining from using the unhealthy materials. Pork is one of these unhealthy and unusable materials which unfortunately, due to lack of sufficient awareness, is still consumed by some.
