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: Marital conflicts have great impact on social, economic and cultural aspects of the couples and their children. New Psychological interventions like “Imago Relationship Therapy” (IRT) have been widely used for resolving these conflicts. This study examined the efficacy of couple dialogue technique on marital relationship and children`s behavior in Iranian society. Methods and Materials: In a Clinical Trial study eighty consecutive couples refered to general pediatric clinics due to their children’s diseases, randomly allocated to intervention group(couple dialogue technique) and control group (consult usual treatment method) in consultation center. They filled "Distance and Isolation Questionnaire" and "Gottmann Love and Respect Scale" at baseline, post treatment and three months after intervention as follow up all of them. General linear Model with Repeated Measurements was used to analyze the data. Results: In this study, scores of mutual love and respect in marital relationship (Gottmann scale) and scores in Flooding, Loneliness and Retreatment subscales of Distance and Isolation Questionnaire had a better condition in IRT group just after the trial (P<0.05) but after three months, the differences between two groups were only marginal significant (P<0.1). In Parallel lives` subscale, scores were decreased in two groups, but right after trial there was not significant scores of the groups did not difference between scores. Scores after three months in IRT group was significantly lower in compare to control group. Scores of CBCL have not statistically significant differences in both groups at any time (P>0.05). Conclusion: This study revealed couple dialogue technique was an effective intervention in solving marital conflicts in Iranian population but had not a significant effect on children’s behavioral profile. This may be due to other factors or insufficient duration of intervention and needs more investigation and needs more investigation.

Previous study show that arrest and retardation in embryo development can produced by low temperature exposure. We aimed to evaluate the effect of Ethanol on growth and development of mouse two-cell arrested embryo. Material and methods: The 4-6 week old female mice were coupled with male mice following superovulation and positive vaginal plaque mice were killed 48 hour after HCG injection by cervical dislocation method. Two cell embryo were collected in RPMI medium and divided and cultured (in M16 medium) in three groups. The 2nd and 3rd groups were exposed to 4°C for 24 hour in order to delay and arrest for cleavage and developmental rate. The 2nd group (2nd control) were incubated immediately, while the 3rd group (experiment) were exposed to % 0.1 Ethanole for 5 minutes and the 1st group (1st control) without any exposure to low temperature group were incubated . Results: The data analysis by one-way ANOWA show that the developmental rate of embryos exposed to low temperature (4°C) significantly decreased (P=0.001), retardation and arrest being produced. The mean of cleavage rate between groups were not significantly affected, but the mean percent of degenerated embryos between groups have significant differences (P=0.045). On the other hand the mean percent of morulla is significantly different between groups (P=0.005) similarly the mean percent of blastocyst and hatched blastocyst have significant differences between groups (P=0.014) (P=0.001) after 120 hr evaluation. Conclusion: Effect of %0.1 Ethyl-alchol on arrested two cell embryos can significantly increase the mean percent of morulla and development up to blastocyst and hatching blastocyst stage related to control group, without any significant effect on cleavage rate

Background: Urolithiasis is one of the causes of renal colic. The annual incidence of this disease is 1-2/1000 people. Due to the severity of pain, adverse effects of routine treatments and incomplete pain relief, more effective methods of treatment have always been sought for. Alhagi Pseudalhagi distillate is a traditional herbal medication used for urolithiasis. Due to its wide availability and no previous report of adverse effects, we decided to evaluate its impact on ureteral stone expulsion. Materials and Methods: In this single-blind randomized clinical trial, 100 renal colic patients whom visited in Arak Vali-asr Hospital or its clinics were divided into two groups. Group1 received Thiazide, Tamsulosin, and analgesics and group 2 received Alhagi Pseudalhagi distillate in addition to aforementioned drugs. The patients were followed upto 4 weeks and the stone expulsion rates and their times were compared. Results: The average stone sizes for groups 1 and 2 were 4.66 and 4.32 mm, respectively (p=0.128). Stones in both groups were mostly located in lower ureter (p=0.551). Expulsion occurred in 40% of group 1 and 66% of group 2 patients (p=0.009). The mean expulsion times for groups 1 and 2 were 11 and 9 days, respectively (p= 0.291). Conclusion: Alhagi Pseudalhagi distillate had a significant effect on the rate of stone expulsion and it is likely to decrease the time needed for the passage of Urolithiasis stones.

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: Candida vaginitis which is mostly caused by Candida albicans is the second common cause of vaginal candidiasis in women. This study was designed to determine the clinical symptoms of Candida vaginitis and their relationship with the types of Candida species in women referring to the clinics of Shiraz University of Medical Sciences. Materials and Methods: In an analytical study, over a seven month period of sampling, through the examination of the history of 1100 patients, 450 were identified with chief complaints regarding genital infection. Samples were obtained from 280 of these patients according to their histories and the characteristics of their vaginal discharges. Of these patients, 105 were diagnosed with Candida vaginitis. The analysis of Candidal species was done through germ tube and chlamidospore agar tests. Results: Urogenital itching was severe in more than 43.8% of patients. White color genital discharges were more observable than other symptoms (88.6%). In negative Candida culture samples, severe itching, white color discharge, and disuria were reported to be 23, 80.8, and 43.5%, respectively. Candida albicans composed 70.5% of the samples. Colony count was between 51 and 500 in 49.5% of all samples. There were no significant relationships between colony count and rate of itching, family planning program, and other symptoms. Conclusion: Due to the uncertainty of diagnosis of this disease according to clinical symptoms and also, due to the consistency and resistance of Candida species, using culture method is recommended as a standard method of diagnosis.

Background: Bacterial vaginosis is one of the most common infections in women at reproductive age. Although metronidazole is recommended as the first-line treatment, it has various side effects which make it difficult for patients to continue the treatment. Thus, the need is felt for finding a medication with fewer side effects. The aim of this study is to compare the effects of micosin vaginal cream (made of garlic) and metronidazole vaginal gel on treatment of patients with bacterial vaginosis. Materials and Methods: This study was a clinical trial which was conducted on 100 married women, aged 18-44, whose infection with bacterial vaginosis was diagnosed through clinical Amsel criteria. The participants were randomly divided into two groups of 50 persons each: Micosin vaginal cream and metronidazole vaginal gel. Patients identified with tricamona or candidiadis infections were excluded from the study. Treatment period in each group lasted for seven days. Clinical Amsel criteria and patient complaints were again checked 2 to 7 days after completion of the treatment period, and the side-effects were registered. Results: Following the treatment with micosin vaginal cream and metronidazole vaginal gel, patient complaints and clinical Amsel criteria showed a significant decrease (p<0.05), in a way that clinical recovery rates in micosin and metronidazole groups were 80% and 70%, respectively. Conclusion: Micosin vaginal cream seems to be an appropriate alternative for metronidazole vaginal gel in treatment of bacterial vaginosis.
