Background: The prevalence and incidence of cancer in different parts of the world have different patterns. To recognize the frequency of malignancies in different social groups according to climatic conditions is considered as the primary component of prevention programs at different levels. This study was conducted to investigate the epidemiology, survival rates and geographical epidemiology of breast cancer in Markazi province.

Materials and Methods: In this epidemiological study, needed data were obtained from cancer registration program and death registration data. The data were analyzed by using SPSS software version 16 and Winpepi and significant level was 0.05. And to draw a map to show the breast cancer incidence rate in Markazi district, Arc view software was used.

Results: Out of the 400 cases recorded during the 5-year, 8.5% died due to breast cancer. 5-year survival rate was 87% and there was a significant correlation between survival rate and age. Most records were related to the age group 49-40 years and the highest incidence rate was in Arak. The trends of incidence rate was not significant.

Conclusion: The results showed that 5-year breast cancer survival rate is more than some other places which could be due to new and improved methods of treatment and methods of screening and early detection of disease. Other aspects of the epidemiology of the disease is similar to other parts of Iran.

Background: Occult hepatitis C virus (HCV) infection is defined as the presence of HCV-RNA in liver or peripheral blood mononuclear cells (PBMCs) in the absence of detectable hepatitis C antibody (anti-HCV) or HCV-RNA in the serum. Although occult HCV infection is less aggressive than classic chronic HCV infection, nevertheless it is important in management of hemodialysis (HD) patients. Occult HCV infection has been described in two different clinical settings: in patients with normal liver enzymes or in patients with abnormal values of liver enzymes. The aim of this study was to detect the occult HCV infection in hemodialysis patients with elevated liver enzymes.

Materials and Methods: This cross sectional study was performed in hemodialysis patients referring to 3 dialysis units in Tehran. In 30 anti-HCV negative HD patients with elevated liver enzymes, presence of HCV-RNA in plasma samples was tested by Reverse Transcriptase-Nested Polymerase Chain Reaction (RT-nested PCR). In cases with negative anti-HCV and plasma HCV-RNA, HCV-RNA was checked in PBMC specimens by RT-nested PCR.

Results: A total of 30 HD patients with mean age 54.4± 14.1years and mean dialysis duration 81.2 ±64.4 months were enrolled in the study. All HD subjects were negative for HCV-RNA in plasma and occult HCV infection with RT-nested PCR method.

Conclusion: Occult HCV infection was rare in HD patients with elevated levels of liver enzymes.

Background: Thymus is essential in creating some of the disorders and diseases. Treatment of these disorders (particularly tumors and myasthenia gravis) is possible with complete removal of the thymus.

Materials and Methods: In this retrospective study over a period of eleven years, all case of thymectomy performed at the Department of Thoracic Surgery of shahid Beheshti University has investigated. Variables examined included age, sex, primary diagnosis, surgical technique, complications and results of surgery.

Results: The total number of patients was 50 (46% male and 54% female) with a mean age of 85.14 ± 46.41 years. Primary diagnosis was myasthenia gravis in 40% of patients and thymoma in 42% of them. Myasthenic symptom was the most common presenting symptom (50%). Radical thymectomy surgery was performed in 64% of patients. Fever and atelectasis (10%) and respiratory failure (12%) were the most common postoperative complication and mortality rate was 4%. Thymoma (64%) and thymus hyperplasia (20%) were the most frequent pathology. Clinical symptoms were gone or greatly reduced in 40% of patients. The majority of them had a primary diagnosis of myasthenia gravis (36%). 50% of patients have been followed up. The mean follow-up time in these patients is 32.20 ± 36.41 months.

Conclusion: Thymectomy surgery with low morbidity and mortality, provides the possibility of treatment of thymic lesions. Especially Thymoma and Myasthenia Gravis

Background: Planning of educational programs to inform the people about the prevention of diseases such as cancers is necessary. This study was conducted to determine the effect of educational interference based on HBM on practices of women about gastric cancer.

Materials and Methods: In this semi-experimental study, 88 women participated from Arak. The subject were randomly divided in two groups, experimental group and control group (each group includes 44 women). Inclusion criteria were absence of cancer, Iranian nationality, age over 18 years, living in the city. Data collected with a questionnaire based on HBM and performance checklist about colorectal cancer prevention was used in order to evaluate the effectiveness of the educational program. Intervention was done in 1 month consist of 3 session each session 45 minutes. Three months later data were recollected and analyzed.

Results: In this study, the mean age in case and control group was 38.3±9.6 and 36.3±11.1 years respectively, with no significant differences (p=0.381). Average scores of knowledge and practice in experimental was 72.8±13.06 and 30.81±6.2 respectively group before the intervention, which was 88.05±12.2 and 65.3±8.9 respectively after the intervention (p<0.05). Moreover before of intervention susceptibility, severity and percieved benefit about practice of mothers was moderate but after intervention the entire items between experimental and control groups was significantly different (p<0.05).

Conclusion: Finding of this research confirms the effect of Health Belief Model on prevention from gastrointestinal cancer in women of Arak.

Background: Drugs residual discharge into the environment through municipal and hospital wastewaters is one of the emergent environmental problems. Imipenem as a professional hospital antibiotic is widely used against gram- positive and negative bacteria and with entrance to the aquatic environments could prompt a lot of risks such as bacteria resistance, allergies, spoiling alga and daphnia and interrupting in wastewater treatment processes. Therefore there is a command to develop a method for extraction and determination of Imipenem from hospital sewage.

Materials and Methods: Solid phase extraction (SPE) was used to extract Imipenem from samples. Recovery percentage calculated at different pH of 3 and 7. The extracted samples analyzed by High Performance Liquid Chromatography (HPLC) equipped with UV detector. HPLC operated using borate buffer/methanol as mobile phase at flow rate of 0.7 ml/min, column temperature of 20 °C, and UV wavelength of 280-300 nm.

Results: Maximum recovery percentage was obtained 68% at pH=7. The best condition for HPLC was 80:20 ratio of borate buffer/methanol with pH=7.5 and at UV wavelength of 300 nm. Linearity calculated 0.9829, primary and intermediate precision both were more than 95%. Limit of detection (LOD) and limit of quantification (LOQ) were 3 and 10 µg/l respectively.

Conclusion: The method could simply and with significant reliability be applied to extract and determinate Imipenem in complex hospital wastewater matrixes.

Background: Considering the increased activity of hypothalamic orexinergic neurons due to morphine administration, and its extensive projections to the hippocampus, it is probable that morphine effect on CA1 neuronal function is mediated by orexinergic system. So the effect of hippocampal orexin-1 receptors (OX1R) blockade on CA1 baseline synaptic response and short term synaptic plasticity was investigated.

Materials and Methods: In this experimental study, animals received morphine 10 mg/kg/12h/(SC) for 10 days. SB-334867-A, OX1R antagonist (0.5&mug/0.5 &mul), was microinjected intrahippcampally for OX1R inhibition before each morphine injection. Baseline synaptic response and short term synaptic plasticity were evaluated by field potential recording. fEPSP was recorded from CA1 following Schaffer collaterals stimulation. After Input/Output construction, short term synaptic plasticity was induced by paired pulse stimulations.

Results: Chronic use of morphine did not affect the baseline synaptic response (p>0.05). SB- 334867-A microinjection in CA1 did not have any effect on baseline synaptic response in morphine dependent rats. Morphine increased paired pulse index (PPI) at 80 ms inter pulse interval (IPI, p<0.05). SB-334867-A pretreatment did not affect this morphine induced PPI change.

Conclusion: The results suggest that orexin-1 receptors (OX1R) do not mediate the effect of morphine on baseline synaptic response and short term synaptic plasticity in CA1 area of the hippocampus.

Background: Hematopoietic stem cell transplants are routinely used to treat patients with cancers and other disorders of blood and immune systems. Osteoblasts constitute part of the stromal cell support system in marrow for hematopoiesis by participating in the formation of the HSC niche. It is believed that interaction between hematopoietic cells and bone forming osteoblasts regulate each other’s function. It is established that acute blood loss in animal models activates bone formation and niche development because of EPO stimulation. In this experimental study we have examined the co-culture of HSCs derived from cord blood which treated with EPO in vitro, on osteoblastic differentiation of mesenchymal stem cells.

Materials and Methods: In this experimental study MSCs isolated from bone marrow and co-cultured with CD 34+ CD38- HSCs isolated from cord blood. These co-cultured cells were treated with different doses of erythropoietin for 14 days, after that RNA were extracted from MSCs and analysed with RT-PCR to evaluate the expression of osteopontin and osteocalcin. Alizarin red and alkaline phosphatase staining were done for osteoblastic differentiation.

Results: Osteopontin and osteocalcin were expressed in MSCs. Cellular staining were positive for osteoblastic differentiation. Differentiated cells expressed osteoblastic markers.

Conclusion: These data suggest that EPO regulates the osteoblastic differentiation from bone marrow MSCs in vitro.

Background: Environmental signals have a crucial role in development of brain’s structure and function during critical period of brain development. Gt was valuated the devebpmental effeck in developmental effect of visual deprivation on synaptic plasticity of Dentate Gyrus neurons was evaluated.

Materials and Methods: This experimental study was carried on 2 groups (n=48) rats kept in standard 12-hour light/dark condition (Light Reared-LR) or in complete darkness (Dark Reared-DR) since birth throughout the study. Each group, in turn, was divided into 3 groups of 2, 6 and 10 weeks old subgroup (n=8 for each). Stimulating the perforant path, field potentials were recorded in the Dentate Gyrus area for 30 minutes. Then, the tetanic stimulation was applied to the Schaffer collaterals and the field potentials were pooled for 120 minutes post-tetanus in all animals.

Results: The basic responses of the LR animals decreased and the amplitude of the DR rats increased, across aging. After the LTP induction, amplitude of responses increased in all groups but the amount and stability of them were lower dark reared in animals than the LR ones.

Conclusion: Change in environmental visual signals impairs basic response and LTP induction in neurons of Dentate Gyrus area of hippocampus.

Background: Nitric oxide is synthesized in endothelial cells by eNOS and acts as a pleiotropic regulator involved in carcinogenesis. Most gastric cancers develop from stomach epithelial cells therefore, NO may play a role in their development. Polymorphisms of eNOS have been shown to be associated with cancer susceptibility. In the present study, we investigated the association of the eNOS genotypes with gastric cancer risk in Guilan Population.

Materials and Methods: In this case-control study, we analyzed the Glu298Asp polymorphism of eNOS in 87 patients with gastric cancer and 90 healthy controls. The genotyping of eNOS polymorphism was performed using polymerase chain reaction–restriction fragment length polymorphism assays. All statistical analyses were conducted by the MedCalc statistical software.

Results: No association between the eNOS genotypes and gastric cancer risk was found. Among the 87 patients, 45 had Glu/Glu, 38 were Glu/Asp, and 4 were Asp/Asp. In the control group, 44 had Glu/Glu, 40 were Glu/Asp, and 6 were Asp/Asp. We found no significant differences in allele and genotype frequencies between control and patient specimens.

Conclusion: We found that there was no association between this polymorphism and gastric cancer risk. Results suggest that eNOS polymorphism may play a role in inhibition of gastric cancer. However, larger population-based studies are needed for clarifying the role of eNOS polymorphism in gastric cancer.

Background: Vascular endothelial growth factor (vegf) is one of the most important regulator of angiogenesis, there are some reports about the relation of VEGF over expression and progression of tumor in several cancers. The aim of this study is assay of four VEGF isoforms expression in breast cancer tumor samples.

Materials and Methods: 25 breast cancer tumor samples and 25 health samples were used in this study, mRNA was extracted from each sample and then cDNA was made. The expression of four isoforms VEGF121, VEGF165, VEGF183 and VEGF189 was measured by real time reverse transcription PCR (RT-PCR) and gel electrophoresis.

Results: Among the four isoforms, VEGF165 and VEGF 121 had maximum and VEGF 183 and VEGF 189 had minimum expression level in all samples. The total expression level of VEGF had a significant increase in tumor samples in comparison with the control samples (4/6, p<0.01).

Conclusion: There is a significant relation between the VEGF over expression and breast cancer tumor formation, which it can be used as a prognosis marker of breast cancer in future.

Background: Statins are the most effective drugs for treatment of elevated level of cholesterol. In addition, they exhibit other effects unrelated to their lipid lowering effects (pleiotropic actions). In recent years, experimental and clinical evidences demonstrate that statins exert anti-inflammatory properties. The aim of this study is evaluation of association Atorvastatin in reduction of peak threshold in patients with permanent pacemaker.

Materials and Methods: In these clinical trial 64 eligible patients that candidate for permanent pacemaker enrolled. After in formed consent patients randomly divided to two equal groups. In first group atorvastatin 20 mg/daily administered orally for six weeks and second group considered as control. Peak atrial and ventricular threshold were measured in beginning of study and in sixth week. The data collected and analyzed and p<0.05 considered statistically meaning full.

Results: from 32 subjects in Atorvastatin group 17 (53.12%) were male and 15(46.87%) were female. Average mean age in Atorvastatin and control group was 72.43±17.27 and 68.59 ±10.98 years, respectively. No difference showed in atrial and ventricular threshold in two groups at beginning of study. At end of study atrial threshold in atorvastatin and control group were 0.55±0.23 and 0.45±0.19 respectively (p=0.4) and ventricular threshold in atorvastatin and and control group were 0.73±0.23 (p=0.4).

Conclusion: There is no association between atorvastatin therapy and reduction in pacemaker peak arterial and ventricular threshold.

Background: Doxorubicin is a chemotherapeutic agent still in widespread use in hematologic malignancies. A side effect of anthracyclines such as doxorubicin is the activation of nuclear factor-&kappaB (NF-&kappaB), a potent inducer of antiapoptotic genes, which may blunt the therapeutic efficacy of the drugs. In this study, the effect of indole -3-carbinol (I3C) on the activation NF-&kappaB and the anti-apoptotic genes whose expression is regulated by NF-&kappaB was assessed in NALM-6 cells.

Materials and Methods: NALM-6 cells were preincubated with various concentrations of I3C and then treated with doxorubicin. Cellular DNA content assay and Annexin V-FITC staining were performed by flowcytometry for evaluation of apoptosis. For assessing the effect of I3C on the expression of XIAP, survivin, and nuclear p65 proteins, NALM-6 cells were pretreated with I3C and then incubated with doxorubicin. Whole-cell and nuclear extracts were prepared for Western blot analysis. A paired t-test was conducted to evaluate the results.

Results: DNA histogram analysis of NALM-6 cells indicates a combination of I3C with doxorubicin significantly escalated the percentages of sub-G1 population cells compared with doxorubicin - only treated group (p<0.05). Annexin V-FITC staining also showed that cotreatment of NALM-6 cells with I3C and doxorubicin significantly increased the proportion of Annexin-V positive cells in comparison with the doxorubicin treated cells (p<0.05). The western blot analysis indicated I3C significantly inhibits both doxorubicin -induced nuclear translocation of p65 and the expression of doxorubicin-induced NF-&kappaB target.

Conclusion: Our results indicated that using natural non-toxic inhibitors of NF-&kappaB such as I3C in combination with anthracyclines might be a rational combination therapy for BCP-ALL cells in which NF-&kappaB is constitutively active.

Background: Due to increasing antibiotic resistance, it is important to identify the antimicrobial activity of herbs. This experimental study aimed to evaluate the antimicrobial activity of herbal extracts of common hop (Humulus lupulus) and oak (Quercus castaneifolia) against several microbial standard strains.

Materials and Methods: The alcoholic and aqueous extracts of H. lupulus and Q. castaneifolia were extracted. The inhibitory effects of herbal extracts were evaluated against the microbial standard strains (Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans) by both agar diffusion and macrobroth dilution methods. In the agar diffusion method, concentrations of extracts were 125, 250, 500 and 1000 mg/ml. In order to determine the MIC, serial dilutions were prepared with a range from 1 to 512 mg/ml.

Results: Alcoholic extract of both hop and oak showed higher inhibitory effect against microbial standard strains, compared to the aqueous extract. Staphylococcus aureus ATCC 29213 and Candida albicans ATCC 76615 showed higher susceptibility to both alcoholic and aqueous extracts compared to Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853. Statistically significant difference was found on the MIC of alcoholic and aqueous extracts (p<0.05).

Conclusion: This study revealed the considerable inhibitory effects of herbal hop and oak extracts on the various microorganisms, including bacteria and fungi. Although more research is needed in this field, they can be used as new antimicrobials in medicine.

Background: Estrogen hormone regulates cell proliferation in breast tissue physiologically. Evidences show that changes in estrogen signaling pathways, including the receptor alpha (ER&alpha), happen during breast cancer progression. ER&alpha is expressed in most breast tumors and its association with the development of low-grade tumors has been demonstrated. Single nucleotide polymorphisms (SNPs) in genes may differ in susceptibility to cancer and result in different respond to treatment in different populations. The present study aimed investigated the association between single nucleotide polymorphisms (rs2234693: C/T) in gene ESR&alpha in patients with breast cancer.

Materials and Methods: In this case-control study 150 women with breast cancer and 142 healthy women without a family history of breast cancer were enrolled. DNA was extracted from blood samples. After primer design, technique of PCR-RFLP was used and samples were genotyped by acrylamide gel electrophoresis. Statistical analyzes were performed using SPSS version 20 and chi square test and Final findings were specified.

Results: TT and CT genotypes for ra2234693: C/T site compared with the CC had 5.5 and 1.5-fold increased risk respectively. Statistically significant differences were found between cases and controls for fibrocystic disease and age at menarche.

Conclusion: We not found an association between C/T polymorphism and breast cancer. But CC and TT genotypes of this polymorphism in estrogen receptor alpha gene related with breast cancer that are consistent with the findings of some other researchers.

Background: Newcastle disease virus (NDV) is one of the major pathogens in poultry and vaccination is intended to control the disease, as an effective solution, yet. Fusion protein (F) on surface of NDV, has a fundamental role in virus pathogenicity and can induce protective immunity, alone. With this background, here our aim was to construct a baculovirus derived recombinant bacmid shuttle vector (encoding F-protein) in order to express it in insect cell line.

Materials and Methods: In this experimental study, at first complete F gene from avirulent strain La Sota of NDV was amplified by RT-PCR to produce F cDNA. The amplicon was cloned into T/A cloning vector and afterwards into pFastBac Dual donor plasmid. After the verification of cloning process by two methods, PCR and enzymatic digestion analysis, the accuracy of F gene sequence was confirmed by sequencing. Finally, F-containing recombinant bacmid was subsequently generated in DH10Bac cell and the construct production was confirmed by a special PCR panel, using F specific primers and M13 universal primers.

Results: Analysis of confirmatory tests showed that the recombinant bacmid, expressing of F-protein gene in correct sequence and framework, has been constructed successfully.

Conclusion: The product of this F-containing recombinant bacmid, in addition to its independent application in the induction of protective immunity, can be used with the other individual recombinant baculoviruses, expressing HN and NP genes to produce NDV-VLPs in insect cell line.

Background: Breast cancer is the most common cancer and one of the main causes of cancer-related death all over the world that has become a major public health concern. Human apurinic/apyrimidinic endonuclease (ApE1) is a multifunctional protein that has an important role in the base excision repair (BER) pathway. Single- nucleotide polymorphism T>G found in exon 5 led to substitution of Asp>Glu at codon 148 (Asp148Glu). In this case-control study, we aimed to evaluate the association of this polymorphism on the risk of breast cancer in Guilan population.

Materials and Methods: To study gene polymorphism APE1 (Case- Control), blood samples were collected from 75 patients diagnosed with breast cancer and 75 control subjects, and genotyped by allele-specific PCR (AS-PCR). To estimate the association between genotype and allele frequencies in cases and controls, Chi-Square analysis was used.

Results: Analysis revealed no significant differences were found in genotype and allele distributions of ApE1 Asp148Glu polymorphism between breast cancer patients and controls (p=0.1, p=0.6 respectively) in this population.

Conclusion: Data from this study indicated no significant association between the Asp148Glu polymorphism and breast cancer risk (p=0.1). Further study is needed to clarify the impact of Asp148Glu polymorphism on the breast cancer.

Background: Exclusive breastfeeding for the first six months after delivery plays a crucial role in preventing infants morbidity and mortality. Exclusive breastfeeding intention during pregnancy is one of predictors of this behavior. Determining the effective factors in exclusive breastfeeding intention helps plan for promoting breastfeeding intention and behavior. The aim of this study is to determine predictive factors of exclusive breastfeeding intention in pregnant women, based on the theory of planned behavior.

Materials and Methods: This analytical study was conducted in 2014 on 224 primigravide women referred to Health Centers of Kashan. The samples were randomly selected from 16 health centers. The mothers completed the questionnaires of demography, intention, attitude, subjective norms and the perceived behavior control. A linear regression analysis was used to identify independent predictors of the exclusive breastfeeding intention.

Results: In regression model, the perceived behavior control (&beta=0.42, p<0.001), attitude (&beta=0.27, p<0.01) and subjective norms (&beta=0.18, p=0.059) were predictors of the exclusive breastfeeding intention. This model could explain 63% of the variance of the exclusive breastfeeding intention. The knowledge and demographic factors were not predictors of the intention.

Conclusion: The results reveal the perceived behavior control, attitudes and subjective norms could predict exclusive breastfeeding intention, so they should be considered as general guidelines in designing educational interventions in order to improve exclusive breastfeeding in women.

Background: Missed abortion refers to pregnancy products remain dead with age less than 20 weeks in the womb for several weeks. This study was designed to evaluate the efficacy of castor oil on cervical ripening in the treatment of abortion.

Materials and Methods: This triple blind clinical trial was done on 72 women with missed abortion who were divided into two groups of 36 patients based on odd or even numberd of cases. The case groups received 800 mg vaginal misoprostol and 60 ml castor oil mixed with fruit juice and control groups received 800 mg vaginal misoprostol and 60 ml placebo with fruit juice, respectively. In both groups, if needed, 3 doses of vaginal suppository 800 mg were repeated with at least 24 hours. After the disposal of pregnancy products, sonography and curettage were performed if necessary.

Results: During the intervening period, the time of the opening of the cervix in the intervention group was shorter than control group and there was a statistically significant difference (p=0.032). Also, the control group required a higher frequency of administration of misoprostol than intervention group and the difference was statistically significant (p = 0.037).

Conclusion: It seems that the castor oil can be effective on cervical ripening for treatment of abortion.

Background: Upper gastrointestinal bleeding is a common medical emergency condition which can be very costly with potential risks. Prompt evaluation of the patients’ status and determination of the risks involved are of utmost significance. Rockall score is one of the Methods determining the risk of bleeding. The aim of the present study was to determine sensitivity, specificity and negative and positive predictive values of Rockall scoring system during a 3-month follow-up period in patients with upper gestronintestinal bleeding.

Materials and Methods: 340 hospitalized patients with acute upper gastrointestinal bleeding in Imam Reza hospital were studied from December 2013 to September 2014. The full and clinical Rockall scores, sensitivity, specificity and negative and positive predictive values were specified for all the subjects who were followed for 3 months in relation to complications and mortality.

Results: Of all patients, 204 were males and 136 were females who 15.6% of the subjects had a clinical Rockall score under 3, with 84.4% having a score over 3. In relation to endoscopic Rockall score, 15.6%, 66.8% and 17.6% of the subjects had a score under 3, between 3-8 and over 8, respectively. During the 3-month follow-up period, in the low-risk group, 92.5% did not exhibit hemorrhage again, 3.8% had one recurrent episode of hemorrhage, 1.9% exhibited 2 hemorrhage episodes, with 1.9% having 3 hemorrhage episodes. In the moderate-risk group, 90.9% experienced no recurrence and 9.1% exhibited 1 case of recurrent hemorrhage (p=0.4). There was no mortality in the low-risk group. In the moderate-risk and high-risk groups, the mortality rates were 8.07% and 22.7%, respectively (p<0.001). The sensitivity and specificity of the test were calculated at 11.1% and 81.1%, respectively. The positive and negative predictive values were 5% and 91.4%, respectively.

Conclusion: With due attention to the specificity of 81.8% and negative predictive value of 91.4% for the Rockall score, it might be guaranteed the patient will not suffer from the complications resulting from recurrence of hemorrhage. Given the low sensitivity of the test, the test is not appropriate to rule out disease.

Background: Heavy menstrual bleeding has a negative impact on quality of life. In this study, the effect of hydroalcoholic extract of capsella bursa pastoris on menorrhagia is evaluated.
Materials and Methods: This clinical trial was carried out on 90 women with complaint of heavy menstrual bleeding. Samples, after a control cycle of primary bleeding, were randomly divided to capsella bursa pastoris and control groups. Both groups were subjected to mefenamic acid treatment with 500 mg every 8 hours, from the first day to the end of bleeding, up to seven days, for two consecutive cycles. In capsella bursa pastoris group, in addition to mefenamic acid, capsella bursa pastoris capsule 500 mg every12 hours, from the first day to the end of bleeding, up to seven days, was prescribed. In control group, instead of capsella bursa pastoris capsules,it^,s placebo was prescribed with the same order. Data were checked and compared before and after treatment using SPSS software.
Results: The average amount of bleeding reduced in capsella bursa pastoris group from 135.27 in control cycle to 69.13 in third cycle and in control group reduced from 133.91 to 75.44 in third cycle(p<0.001). The average duration of bleeding was reduced in capsella bursa pastoris group from 7.38 in control cycle to 5.40 in third cycle and in control group was reduced from 6.91 to 5.31 in third cycle(p<0.001).
Conclusion: It seems that the extract of capsella bursa pastoris can be effective in reducing the amount and duration of bleeding in women of reproductive age with heavy menstrual bleeding.
