Abstract
Background & Objective : Regional anesthesia is a method of choice in cesarean section. But in emergency cesarean sections general anesthesia is usually preferred. On the other hand, intravenous sedative drugs used in general anesthesia induction rapidly crosses the placenta and result in fetal depression. Because of higher prevalence of general anesthesia in Iran it is reasonable to conduct more researches in this field. This study set out to compare the effects of Propofol and Thiopental-Na as induction agents on the neonatal Apgar score and maternal hemodynamic status. Methods: In this double blind clinical trial 60 pregnant women with ASA class I & II were studied. In a random way 30 patients received 2mg/kg Propofol and the rest of them were given 4mg/kg of Thiopental-Na. All these subjects had full term and normal fetus. Pre and post-induction status of the patients was monitored noninvasively after tracheal intubations and during 12 minutes after that. Also time intervals between induction and birth (cord clipping) and between uterus incision and birth were measured. Apgar score of neonates was evaluated through clinical examination in 1st, 5th, 10th and 15th minutes after birth. The data were analyzed in SPSS software using descriptive and analytical statistics such as T-test, chi-square and ANOVA. Results: Apgar score in different times (1.5,10&15 minute) had no significant difference between two groups. (In the 1st minute Propofol was 7.1 ± 2.2 and Thiopental was 74 ± 1.8, in the 5th minute Propofol was 9.2 ± 0.7 and Thiopental was 9.1 ± 0.9) Maximum variation of heart rate and blood pressure in two groups were not significantly different. The time intervals between induction and birth (less than 8 minutes) on the one hand and uterus incision and birth(less than 130 seconds) on the other were similar in two groups. Conclusions : Thiopental-Na and Propofol can be used with similar results for induction of general anesthesia in cesarean section.

Abstract
Background & Objectives : Laryngoscopy and tracheal intubation may lead to tachycardia, hypertension and dysrhythmia or myocardial ischemia. In this double blind study, the effects of midazolam and lidocaine on hemodynamic response to endotracheal intubation have been examined. Methods : 52 ASA class one patients, aged 20-50, who were candidate for elective inguinal hernia surgery with general anesthesia, were randomly assigned to two groups. All patients received normal saline or Ringer's lactate solution (5ml/kg) about 5-10 minutes before induction of anesthesia and were preoxygenated for 3 minutes. Group 1 received midazolam (0.05 mg/kg) and group 2 received lidocaine (1.5 mg/kg) during 3 minutes prior to intubation. Anesthesia was induced with fentanyl (100 µ g) and thiopental (5 mg/kg) and trachea was intubated by the aid of succinyl choline (1.5 mg/kg). Anesthesia was maintained with halothane (0.5-0.75%) and equal proportions of nitrous oxide and oxygen. Systolic and diastolic blood pressure, mean arterial pressure (MAP) and heart rate were recorded before premedication and intubation, as well as immediately two and five minutes after intubation. The data were analyzed by SPSS software using paired t-test. Results : After intubationSystolic and diastolic blood pressure, MAP and heart rate increased in both groups compared to the baseline values. The difference in increasing diastolic blood pressure and MAP between the two groups was significant (p<0.05), but the difference in increasing systolic blood pressure and heart rate between two groups was not statistically significant. The increase in diastolic blood pressure and MAP in group 1 was significantly more than group 2 (p<0.05). Conclusion : Clinically, midazolam was as much effective as lidocaine in controlling response to intubations. Consequently it can be used as an alternative lidocaine in intubations. It has also other priorities such as amnesia, anti-anxiety and anti-agitation.

Abstract
Background & Objectives: Respiatory Distress Synderome (RDS) is one of the major risks of elective cesarian section whose negative health and econemical outcomes are obvious. Maternal prophylactic injection of corticosteroid drugs can reduce RDS of neonate to some extent. On the other hand corticosteroid drugs have some side effects such as delay in the healing of the incision. This study considered the effect of betamethasone on surgical incision. Methods: This study was conducted on 60 primipara women divied into two equal groups that were candidate for elective cesarean. We injected betamethasone (IM) to trial group twice 48 hours poior to operation, (every 24 hours) and complication of surgical incision was clinically evaluated within 7 days after operation in both groups. The data were collected and analyzed by SPSS software chi-square and Fisher tests. Results: Most patients (60%) were 20-30 years old and the average age in both groups was 21. The relative frequency of patients with complication of surgical incision in trial group (betamethasone recipients) was 30% and in control group was 23.33% (the difference between them was not statistically significant). The most common complications were erythema and hyperemia. Other complications observed in 15% of the patients included serousal discharge, local warmness and enduration. Rgarding these complications also there wasn’t a statistically significant difference between two groups. Conclusion: Betamethasone does not increase early onest complications of surgical incision and we can safely use betamethasone prophylactically for fetal maturion in elective cesareans.

Abstract
Background and Objectives: Laryngoscopy and tracheal intubation could lead to hemodynamic responses in the from of hypertension and tachycardia as well as arrhythmia and myocardial ischemia. This alterations can be life-threatening particularly in elderly people. This clinical trial compared the effects of two rapid-onset narcotics, Alfentanil and Remifentanil, on the hemodynamic responses to the induction and tracheal intubation in elderly patients. Methods: This double-blind clinical trial was conducted on 40 subjects aged 65 and above. They were candidate of cataract surgery under general anesthesia. The patients were randomly allocated to two groups of 20. The first group, was gaiven Alfentanil 10 m g/kg and for second group Remifentanil 0.5 m g/kg was injected prior to the induction of anesthesia. Both groups were similiar in the method of anesthesia except in narcotics. The first group was infused with Alfentanil 1 m g/kg/min and Remifentanil 0.1 m g/kg/min was used for the second group. Hemodynamic variations including heart rate, systolic, diastolic and mean arterial blood pressure were measured and recorded eight times (before induction, aften injection, after intubation and five times during anesthesia). Data were analyzed with SPSS software using descriptive and analytical statistics such as T-test, chi squre and ANOVA. Results: Immediately after injection of narcotic drugs, all hemodynamic variants decreased. Howerver diastolic blood pressure in Remifentantil group significantly more than Alfentanil group (P<0.05). After laryngoscopy and tracheal intubation all hemodynamic variants increased and slowly decreased in less than 10 minutes. Systolic, diastolic and mean arterial blood pressure decreased significantly in remifentanil group than alfentanil group (P<0.05). Although heart rate decreased during few minutes after intubation, there was not significant difference between two groups regarding this decrease (P>0.05). Ephedrin was used to treat severe hypotention in those under Remifentanil (11 patients) more than those under Alfentanil (4 patients) (P<0.05). Conclusions: According to the resukts of this study Remifentanil could prevent hemodynamic variation induced by laryngoscopy and treacheal intubation more than Alfentanil. However in some cases Remifentanil leads to hypotension during anesthesia. There is no important difference between two drugs in increasing heat rate after laryngoscopy and intubation.

Abstract
Background & Objectives: Postoperative nausea and vomiting are among the main complication after anesthesia and various methods are used for the prevention of this complication. In this study, the effect of the pre induction use of 10mg Metoclopramide’ 8 mg Dexamethasone and the combination of the both, on decreasing in the rate of nausea and vomiting after cataract surgery in intravenous anesthesia is compared with placebo. Methods: In this double blind clinical trial, one hundred patients of cataract surgery who are appropriate for this study were, randomly divided in to four groups. In the group of placebo (P), 2cc normal saline, in group (M), 10mg metoclopramide, in group (D), 8mg Dexamethasone, and in group (M+D), 10mg metoclopramide and 8 mg Dexamethasone, one minute before the induction of anesthesia was injected. Patients were received the anesthetic drugs in the sameway and after the tracheal intubation infusion of propofol was started. After the end of surgical operation, the appearance of nausea and vomiting in the recovery room and also 6 and 24 hours after the surgery are recorded in the patients' information forms. Finally the data were analysed by statistical software of SPSS and the statistical tests. Results: After the use of these drugs, the rate of nausea in the recovery room decreased from 44% in placebo to 20% in metoclopromide group, 16% in Dexamethasone group, and 8% in combination of metoclopromide and Dexamethasone and the rate of vomiting decreased from 20% in placebo group to 4% in metoclopromide group, 4% in Dexamethasone group, and 0% in combination of these two drugs, both the nausea and vomiting the effect of combination of metoclopromide and Dexamethasone in decreasing of postoperative mausea and vomiting was significant (P<0.05). The 24 hour following of nausea and vomiting, also had the same results. Conclusion: With regrard to the results of this study, implication of the combination of 10mg metoclopromide and 8mg Dexamethasone before the induction of anesthesia remarkably decreased the rate of postoperative nausea and vomiting and is useful for the high risk groups for this complication especially in out patient surgery.

Abstract
Background & Objective: With consideration the daily increased development of outpatient surgeries and high rate of these operations in elderly patients, rapid and safe recovery of patients for coming back to daily life is necessary. In this clinical trial study recovery time and nausea and vomiting after the use of two rapid-onset narcotic, alfentanil and remifentanil in elderly patients has been compared. Methods: In this double-blind clinical trial 40 elderly patients (age above 65) candidated to cataract surgery with general anesthesia were studied. The patients were divided randomly into two groups and for first group alfentanil was injected 10 m g/kg and for second group remifentanil 0.5 m g/kg during 30 seconds one minute before induction. Both two groups were under general anesthesia with same method and during the anesthesia first group took infusion of alfentanil 1 m g/kg/min and second group remifentanil 0.1 m g/kg/min. At the end of surgery the time intervals between end of anesthesia drug adminstration and autonomic respiration, eyes opening with stimulation, verbal response and discharge of recovery room, also the incidence of complications related to narcotic drugs especially nausea and vomiting were recorded. The data were analyzed in SPSS software using descriptive and analytical statistics as T-test, chi square and ANOVA. Results: The time of autonomic respiration in alfentanil group was 2 minutes and in remifentanil group 3.3 minutes,this time in alfentanil groupe1.3 minutes shorter but the difference was not significant. The time of eyes opening with stimulation, verbal response and discharge of recovery room were not significantly different. During recovery incidence of nausea and vomiting in remifentanil group (30% of patients) was significantly more than alfentanil group (5% of patients) (P<0.05). Conclusion: The time of recovery between alfentanil and remifentanil group was not significantly different, but incidence of nausea and vomiting in remifentanil group was higher than alfentanil group significantly.

Abstract
Background & Objectives:Primary Dysmenorrhea (PD) is common gynecology problem in women. It is defined as a menstrual pain that occur in absence of pelvic pathology. PD is common reason of women and girls’ absence from schoole. Pain is main complain of PD but other systemic symptoms like headache, nausea and vomiting, diarrhea, fatigue, irritability and dizziness are common. Many chemical drugs have been used to cure dysmenorrheal, but each has its own side effects. Cinnamomum zeylanicum has been used as an anti-spasmodic agent in traditional medicine . Methods : This study was a placebo-control, triple blind and randomize clinical trial. We research. The efficacy of C. zeylanicum on severity of symptoms with PD Severity of symptoms were assessed. Data were collected by question validated questionnaires. The subjects of study were 47 single women, who sufrred from primay dysmenorrhes, They were randomly selected and their age use between 18-30 years old. We divided them two group, 26 case women in (treatment group) whom needed capsules contain C. zeylanicum and control group whom revided placebo capsules. administered as soon as onset of pain feeling or bleeding, five capsule a day and continued for minimum three days. Severity of systematic symptoms was assessed with Andersch & Milsom verbal multidimensional scoring system. Data were analyzed through by SPSS software. Results: The mean age of women in case and control groups were 20.69 ± 1.93 and 21.7+4.6. There was a significant differences (p<0.001) in the Severity of pain between two groups. The severity of all the systematic symptoms decreased in both groups, but this reduction was not significant between two groups. No significant difference was seen for systematic symptoms between twogroups. In this study, had not been observed any side effects by using of C. zeylanicum . Conclusion: The results our study should that C. zeylanicumcan be effective in reducing the severity of dysmenorrheal, but C. zeylanicum has no sufficient effect on relief of systematic symptoms accompanying with dysmenorrhea.

Abstract
Background & Objectives: Uncontrolled postoperative pain can cause many adverse effects such as tachycardia, hypertension, myocardial ischemia, decreased alveolar ventilation and poor wound healing. In this study we evaluated the preoperative administration of pregabalin in relieving postoperative pain after lower limb orthopedic surgery and reducing the need for opioids and their possible side effects. Methods: This study is a randomized, double-blind clinical trial. It was performed on 60 patients under lower limb surgery in Fatemi Hospital. Patients were randomly allocated to two groups, one group has received a 150 mg pregabalin capsule 2 hours before surgery and the other group has received placebo as a control. In both groups at 2, 6, 12 and 24 hours after surgery, the patients were evaluated and the pain score by a visual analogue scale (VAS), the score of sedation by Ramsay sedation scale and the incidence of nausea and vomiting were recorded in the checklists. Then, the data were analyzed by SPSS v16. P <0.05 was considered significant. Results: In this study 51.7% of patients were male and 48.3% were female. The age averages of these patients in both group were similar (p=0.578). Visual analog pain scores at 2 h after surgery reduced in pregabalin group (p<0.0001). Similar reduction was observed in other studied hours (p<0.0001) too. In the pregabalin group nausea and vomiting scores at all hours, sedation levels at 2 h and 6 h postoperation, and pethidine consumption in all hours have significantly been reduced (p<0.05). Conclusion: Preoperative administration of pregabalin is an effective method for reducing postoperative pain for patients, and with reduction in pethidine consumption, it can decrease problems of opioid usage.

Abstract
Background & objectives : Primary dysmenorrhea (PD) is a common gynecological problem in women. It is defined as a menstrual pain that occurs in absence of pelvic pathology. PD causes school absence and job restriction for many women and girls. Pain is the main complain of PD but other systemic symptoms like headache, nausea and vomiting, diarrhea, fatigue, irritability and dizziness are common. Many chemical drugs have been used to manage dysmenorrhea, but most of them have side effects. Acupoint stimulation therapies, like acupressure, might be an effective intervention for primary dysmenorrhea. SP6 and Liv3 are two important acupoints to improve primary dysmenorrhea. The aim of this study was to compare the effect of acupressure in two points SP6 and Liv3 on primary dysmenorrhea.
Methods: This is a single-blind, randomized clinical trial study. Severity of pain and symptoms were assessed at baseline and also after two menstrual cycles of the investigation using validated questionnaires. 94 non-married women between 18-30 years old, who suffered from primary dysmenorrhea, completed the study (n=50 Liv3, n=44 SP6). The SP6 group received 20 min of acupressure during the initial intervention session and educated to perform the technique twice a day, from 3-5 days before to third days of their menstrual cycle, for two cycles. In contrast, the Liv3 group, performed this method but on Liv3 acupoint. Severity of dysmenorrhea was assessed with Andersch and Milsom verbal multidimensional scoring system. In order to analysis of data, Friedman test and GEE statistics test were used.
Results: In comparison with baseline, severity of pain in both treated groups decreased (p=0.001). But statistical significance was not observed between two groups.
Conclusion: It seems that acupressure on SP6 and Liv3, without any preference, is effective to decrease of severity of pain of dysmenorrhea.

Abstract
Background & objectives: The spontaneous abortion, loss of the fetus until the twentieth week of pregnancy, is one of the most common medical problems in reproductive age. Approximately 15 to 20 percent of all clinically recognized pregnancies lead to abortion. Failure in pregnancy involves economic costs, physical and mental problems for the family and the society. Recurrent spontaneous abortion is a multifactorial phenomenon and this study analyzed chromosomal abnormalities and the prevalence of consanguineous marriages in parents with recurrent spontaneous abortions in Ardabil province.
Methods: A total of 350 patients with at least two spontaneous abortions were analyzed using GTG-banding cytogenetic technique.
Results: Parental chromosomal abnormalities were found in 18 cases (10.28% of couples). Most of abnormalities were structural (72.2%). chromosomal aberrations were found in 10 (55.6%) females and 8 (44.4%) males. Translocations were the most common chromosomal abnormalities (55.6 %) diagnosed in this study. Also, there was a significant correlation between recurrent spontaneous abortion due to consanguineous marriage and chromosomal abnormalities (p<0.05).
Conclusion: According to the significant correlation between recurrent spontaneous abortion and chromosomal abnormalities in this study and previous studies, and also the high rate of consanguineous marriages in Ardabil province population, analysis of chromosomal abnormalities is necessary after genetic counseling for both parents with recurrent spontaneous abortions.

Abstract
Background & Objectives: Gastric cancer is the fourth most common cancer in the world and Ardabil province is in the top ranks in the world. MicroRNAs are non-coding RNA molecules with a length of 18 to 21 nucleotides and due to their regulatory role in post- transcriptional gene expression; single nucleotide polymorphisms (SNPs) could affect their function on target genes regulation.
Methods: Genomic DNA was extracted from peripheral blood of 150 healthy volunteers, which were born and living in Ardabil province, 30 SNPs in microRNA genes have been detected by the Whole Exome Sequencing assay. Then, the obtained results were evaluated using Sanger-based PCR-Sequencing method. The Pearson correlation test was used for finding significant relationships.
Results: After confirming the WES results, the population frequency of the selected variants was compared with the general populations of Iran, Europe and the world. Based on the age-standardized rate (ASR), six variants with significant differences, including rs10061133, rs12220909, rs12983273, rs2292832, rs2505901 and rs6505162 were observed.
Conclusion: According to the previous case-control studies which indicate the association between the variants rs10061133, rs12220909, rs12983273, rs2505901, and rs6505162 and gastric carcinogenesis in various populations, the observed significant differences in our population could imply on the presence of the cancer susceptibility in Ardabil province.

Abstract
Background & objectives: Using medications that decrease postoperative pain and opioid consumption is a widely recommended approach. The aim of this study was to evaluate the efficacy of intravenous Ibuprofen and its complication in controlling pain after abdominal surgery.
Methods: This study was a randomized, double-blind, interventional clinical trial. Sixty patients aged 20 to 60 years were candidates for abdominal surgery (inguinal hernioplasty and appendectomy). Patients were divided into two equal size groups (n=30) using a random block design method. The First group received (400 mg IV) ibuprofen every 6 hours for 24 hours as well as (15 microgram/ml bolus) fentanyl pump with PCA. Second group only received (15 microgram/ml blous) fentanyl pump with PCA.
Results: Demographic characteristics and duration of surgery, ASA class, type of anesthesia and type of surgery were similar in the two groups. Pain severity in 24 postoperative hours was significantly lower in the ibuprofen group compared with the control group. Nausea and vomiting frequency in 24 postoperative hours was significantly lower in the ibuprofen group compared with the control group. Patients belonging to ibuprofen group were significantly more satisfied with their analgesic method.
Conclusion: Results showed that using 400 mg intravenous ibuprofen every 6 hours mitigates postoperative pain, reduces fentanyl consumption and is highly tolerated by patients.

Abstract
Background: Gastric cancer is a type of malignancy that affects the digestive system. Symptoms of gastric cancer are often hard to detect in the early stages, and become more noticeable only after cancer cells have grown inside the stomach wall and spread to other parts of the body. The genetic code of the cancer cells is located within the genome. Synonymous and non-synonymous mutations are two subgroups of SNP codes. The purpose of this study was to investigate the correlation between genetic variants and susceptibility to gastric cancer in Ardabil province.
Methods: The distribution of variants in the genomic DNA of 150 volunteers from the general population of Ardabil was determined using whole exome sequencing. Databases such as Iranome, Alfa, GnomAD, and 1000G were used to compare allele frequencies. After calculating the frequency of variants using standard methods, Pearson correlation was utilized to statistically analyze their correlation with age-standardized incidence rates (ASRs) for gastric cancer in related populations. A p-value below 0.05 was deemed statistically significant for all analyses. Statistical analysis was conducted using IBM SPSS Statistics version 25.
Results: Significant differences in 19 variants , including rs10061133, rs1050631, rs12220909, rs12983273, rs1695, rs2274223, rs2292832, rs2294008, rs2505901, rs2976391, rs33927012, rs3744037, rs3745469, rs4789936, rs4986790, rs4986791, rs6194, rs63750447, and rs6505162 were found between the general population of Ardabil and other populations. A statistically significant difference was observed and reported at the 0.05 and 0.01 levels in relation to the correlation between the desired variants.
Conclusion: Results suggest a correlation between gene variants in carcinogenesis, highlighting the need for functional studies on gene cooperation in gastric cancer development.
