Abstract
Objectives The kinesiopathology model is a new rehabilitation model classifying, evaluating, and treating patients with non-specific back pain. Sahrmann proposed this model based on movement disorder syndromes. The present cross-sectional study aimed to evaluate the radiograph of the linear and angular displacement of the lumbar spine in patients with lumbar flexion impairment syndrome (LFIS) and lumbar extension impairment syndrome (LEIS). Methods In this study, 50 adults aged 18-46 years were enrolled, including 25 patients with LFIS and 25 with LEIS. The eligible participants were referred to the radiology department for radiography in the common position of neutral, full extension, and full flexion position while standing. The White and Panjabi's method was used to measure the linear and angular displacements. Moreover, pain intensity was assessed using the visual analogue scale, and functional disability was investigated using a modified Oswestry Disability Questionnaire. Results The parameter of the linear displacement at the L3-L4 level was significantly different between the two groups (P=0.02). The mean duration of low back pain was longer in the LEIS, compared to the LFIS group (P=0.01). Conclusion In patients with LEIS, compensatory responses occur that cause less linear displacement at the L3-L4 level, compared to the patients with LFIS. Therefore, it is important to design appropriate exercises to better control the linear displacement at the L3-L4 level during the full range of motion in patients with LFIS.

Abstract
BACKGROUND/OBJECTIVES Several clinical tests have been proposed to diagnose lumbar instability, but their accuracy is still in question. The primary purpose of this study was to evaluate the diagnostic accuracy of the clinical lumbar instability tests. The secondary goal was to design a model to detect lumbar instability. DESIGN A prospective diagnostic cross-sectional study. METHOD A sample of 202 patients with chronic low back pain were participated in the study. Five lumbar instability tests including Aberrant movement, Passive lumbar extension, Prone segmental instability, H and I and pheasant tests were compared to flexion/extension radiography as the gold standard for diagnosing lumbar instability using two by two tables. Multiple Logistic Regression analysis was applied to develop a model using demographic information as well as the patients' pain intensity, disability level, lumbar lordosis and the clinical tests. RESULTS Among the five examined tests, Prone segmental instability, H and I and pheasant tests showed very small likelihood ratios and diagnostic odd's ratio. The largest values were for H and I test with the positive likelihood ratio of 1.28 (95% CI: 0.72 to 2.29) and diagnostic odd's ratio of 1.37 (95% CI: 0.66 to 2.83); the diagnostic accuracy measures were smaller for the other studied clinical tests. The model was developed using weight (t = 1.15, p = 0.03) and lumbar lordosis (t = 3.04, p = 0.00) (which showed a significant relationship with lumbar instability) and prone segmental instability test. The final model has the positive likelihood ratio of 2.07 (95% CI: 1.41 to 3.05) and diagnostic odd's ratio of 3.77 (95% CI: 2.03 to 7.01). CONCLUSION Each individual test had very small to no power in discriminating patients with lumbar instability. The developed model just slightly improved the accuracy of radiological instability detection.

Abstract
Background: Nurses in emergency departments are exposed to stress and ethical issues due to the specific nature of their job. Therefore, the aim of the present study was to present a relationship between health anxiety and perceived stress with Moral distress and mediation of turmoil tolerance in emergency department nurses. Methods: This descriptive correlational study was performed on 230 emergency nurses in Tehran in 1399 using available sampling method. In this study, the Cohen, Kamark and Marmelstein (1983) Perceived Stress Questionnaire, Salkowski and Warwick (2002), Simmons and Gahr (2005) Perturbation Tolerance, and Jamton's Moral Perturbation Questionnaire were used. Data analysis was performed by path analysis using SPSS-24 and Amos-24 software. Results: The findings of the study showed that perceived stress (t = 5.58) and health anxiety (t = 7.1) had a positive and direct effect on Moral distress and distress Tolerance(t = 8.33) on Moral distress. The effect is negative and direct (P <0.01). The results also showed that disturbance tolerance has a mediating role in the relationship between perceived fear and health anxiety with moral distress (P <0.01). Conclusion: distress Tolerance mediates the relationship between perceived stress and health anxiety with Moral distress. The findings of this study can be used to improve the degree of distress Tolerance and improve the level of work ethic and reduce the Moral distress of emergency department nurses.

Abstract
Abstract
Background
Ischemic heart diseases (IHD) is the leading cause of mortality, worldwide. Understanding of the status of risk factors contributing to IHD and mortality helps control this public health issue.
Purpose
This study aims to provide global, regional, and national estimates of the trend of IHD burden and deaths attributable to the modifiable risk factors, from 1990 to 2019.
Methods
Using the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 methodology, we evaluated the IHD incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life-years (DALYs). IHD deaths attributable to the different metabolic, behavioral and environmental risk factors were estimated based on risk exposure, relative risks, and the theoretical minimum risk exposure level input from 204 countries and territories, stratified by sex and Socio-demographic Index (SDI). Trends were estimated from 1990 to 2019, with an emphasis on 2010 to 2019.
Results
Globally, there were 21·2 million (95% uncertainty interval [UI] 18·8–23·7) new cases, 9·1 million (8.4–9·7) deaths, and 182·0 million (170·2–193·5) DALYs due to IHD, in 2019. From 1990 to 2019, IHD incident cases, deaths and DALYs increased globally by 29.1·9% (27.0–31·3), 32·4% (25.3–37·8), and 53.9% (42·7–64·3), respectively. Although high SDI regions succeeded to reduce DLAYs due to IHDs by −36.7% (−33.8 to −39.2), low SDI regions faced an increase in DALYs due to IHDs by +104.4% (+75.0 to +135.3). In 2019, the five leading risk factors of deaths due to IHDs were; high systolic blood pressure [2.2 million deaths (1.7–2.7)], high LDL cholesterol [1.7 million deaths (1.2–2.3)], high fasting plasma glucose [1.1 million deaths (0.6–1.8)], high body-mass index [0.8 million deaths (0.5–1.1)], and diet low in whole grains [0.6 million deaths (0.2–0.8)]. From 1990 to 2019, high SDI regions succeeded to reduce the age standardized death rate of IHDs attributable to metabolic risk factors by −60.1% (−61.9 to −57.7), behavioral risk factors by −61.2% (−62.8 to −59.2) and environmental risk factors by −65.8% (−71.4 to −59.3). During the same period, the age standardized IHD death rate attributable to environmental risk factors decreased by −16.0% (−30.4 to −1.6), while the age standardized IHD death rate attributable to metabolic and behavioral risk factors didn't change significantly, in low SDI regions.
Conclusions
During the past two decades despite steadily increase in incident cases of IHDs, the age standardized burden of IHDs has decreased in high SDI regions most probably due to control of attributable risk factors. However, burden of IHDs has increased dramatically in low SDI regions. Preventive measures such as “polypills” for high blood pressure control programs and life-style modification should be prioritized in these settings.

Abstract
Abstract
Background
Hypertensive heart disease (HHD) is a major cause of heart failure, cardiovascular related hospitalizations, and mortality. Diet high in salt is one of modifiable risk factors of HHD that can be controlled by appropriate policies.
Purpose
This study aims to provide the HHD burden attributable to diet high in sodium in the United States compared to European and the global trends from 1990 to 2019.
Methods
Using the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 methodology, we calculated the HHD, mortality, years lived with disability, years of life lost, and disability-adjusted life-years (DALYs). Diet high in sodium was defined as a diet with more than 1,000 milligrams of sodium per day. HHD deaths attributable to the diet high in sodium was estimated based on risk exposure, relative risks, and the theoretical minimum risk exposure level Trends of HHD attributable to diet high in sodium was estimated from 1990 to 2019.
Results
Globally, there were 170·3 thousand (95% uncertainty interval [UI] 31.2 to 459.5) deaths, YLLs, YLDs, DALYs due to HHD attributable to diet high in sodium, in 2019. In the United States, 4525 deaths happened because of HHD caused by the diet high in sodium, with 208.4% rise from 1990. In the European Union, 18,143 deaths happened because of HHD caused by the diet high in sodium, with 78.0% rise from 1990. To address the impact of population aging and population growth, we estimated the age standardized values for burden of HHD attributable to the diet high in sodium. From 1990 to 2019, worldwide age standardized YLL, YLD, and DALY rates per 100,000 for HHD attributable to the diet high in sodium changed by −44.0% (−63.6 to −30.6), +3.7% (−14.3 to +13.6), and −41.8% (−61.3 to −28.8), respectively (Figure 1). In the European Union, age standardized YLL, YLD, and DALY rates per 100,000 for HHD attributable to the diet high in sodium changed by −14.8% (−44.6 to −0.2), −13.5% (−45.8 to −14.0), and −14.8% (−43.5 to −0.9), respectively. Compared to the European Union and the worldwide trends, United Sates had the opposite increasing trend of HHD caused by the diet high in sodium. In the United States, age standardized YLL, YLD, and DALY rates per 100,000 for HHD attributable to the diet high in sodium changed by +110.4% (+42.0 to +631.0), +44.2% (+106.4 to +300.5), and −14.8% (−43.5 to −0.9), respectively. As shown in figure 2, the United States' increasing trend of HHD attributable to the diet high in sodium was caused mainly by the increasing trend observed in men.
Conclusions
Despite worldwide success in the restriction of the diet high in sodium, HHD burden attributable to high consumption of sodium is rising in the United States. This warning results requires public health attention to taking actions such as advocating for healthy diet, restricting foods high in sodium such as fast foods, and increasing the access to low salt foods for working groups.

Abstract
The outbreak of SARS-CoV-2 (COVID-19) has attracted much attention to study its possible presence and airborne transmission. The possibility of COVID-19 airborne transmission in indoor environments is debatable. The present study examined the concentration of viral RNA-containing particles produced directly or indirectly by breathing or coughing of confirmed COVID-19 patients or by carriers without symptoms. Some studies do not accept this method of transmission (COVID-19 airborne transmission). The present study aimed to measure the possible exposure of health care personnel to SARS-CoV-2 particles that may have been suspended in the air to respond to the hypothesis of COVID-19 airborne transmission. Airborne particle sampling was performed using impingement method based on NIOSH (chapter BA) and ASHRAE. Selection of sampling sections was in line with the WHO guidelines. The samples were analyzed using RT-PCR technique. Based on the given results, airborne particles of COVID-19 may present in the air and affect the health of hospital personnel. In fact, the analysis of gene expression in ambient conditions and thereby aerosol transmission of SARS-CoV-2 through air is possible and may lead to occupational exposure of health care personnel. Furthermore, it was found that airborne emission of COVID-19 through the breathing zone of patients, particularly in ICU wards with confirmed cases of COVID-19, may be higher than in other ICU wards. Also, the demonstrated results showed that there is a possibility of reaerosolization (reintroduction) of previously airborne SARS-CoV-2 particles into the atmosphere due to health care personnel frequently walking between different wards and stations of ICU.

Abstract
Alzheimer's disease (AD) is a neurodegenerative condition mostly communal in people of advanced years accompanying various dysfunctionalities especially cognitive impairments. A number of cellular damages, such as amyloid-beta aggregation, tau protein hyperphosphorylation, some neurotransmitter imbalances, apoptosis, oxidative stress, and inflammatory responses are responsible for AD incidence. As a reason for inadequate efficacy, side effects, and pharmacokinetic problems of conventional drugs used for AD, the discovery of novel therapeutic agents with multi-targeted potential is desirable. Protective properties of phytochemicals combat numerous diseases and their vast acceptance and demand in human beings encouraged scientists to assess their effective activities. Zingiber officinale, gingerol, shogaol, and borneol were evaluated against memory impairments. Online databases including; Web of Science, Scopus, Embase, Pubmed, ProQuest, ScienceDirect, and Cochrane Library were searched until 3th February 2020. In vitro, in vivo, and clinical studies are included after screening their eligibility. Mostly interventive mechanisms such as; oxidative stress, neuroinflammation, and apoptosis are described. Correlation between the pathogenesis of AD and signaling pathways is explicated. Results and scores of cognition measurements are clarified due to in vivo studies and clinical trials. Some traditional aspects of consuming ginger in AD are also mentioned in the present review. In accumulation ginger and its components possess great potency for improving and abrogating memory dysfunctions but conducting further studies to evaluate their pharmacological and pharmaceutical aspects is required.

Abstract
This study investigated the effects of garlic on anxiety- and depression-related behaviors and brain oxidative markers in streptozotocin (STZ)-induced diabetes in rats. Fifty-six male Wistar rats were randomly divided into seven experimental groups (n = 8/group): control, diabetic + saline, diabetic + garlic, diabetic + imipramine, and diabetic + diazepam groups. Animals received garlic homogenate (0.1, 0.25, and 0.5 g/kg) for 10 days. At the end of the treatments, anxiety- and depressive-related behaviors were evaluated by elevated plus maze (EPM) and forced swimming test (FST), respectively. Superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities and malondialdehyde (MDA) levels were measured in the brain. Diabetic + garlic (0.5 g/kg) group showed lower anxiety- and- depressive-like behaviors as compared to the diabetic rats. Furthermore, garlic treatment (0.5 g/kg) attenuated MDA levels and enhanced SOD and GPx activities in the brain. Our findings indicate that garlic alleviates anxiety- and depression-related behaviors in the diabetic rats possibly by attenuation of brain oxidative stress.

Abstract
OBJECTIVES Maternal high-fat diet (HFD) consumption has been linked to metabolic disorders and reproductive dysfunctions in offspring. Troxerutin (TRO) has anti-hyperlipidemic, anti-oxidant, and anti-inflammatory effects. This study examined the effects of TRO on apelin-13, its receptors mRNA and ovarian histological changes in the offspring of HFD fed rats. MATERIALS AND METHODS Female Wistar rats were randomly divided into control diet (CD) or HFD groups and received these diets for eight weeks. After mating, dams were assigned into four subgroups: CD, CD + TRO, HFD, and HFD + TRO, and received their respective diets until the end of lactation. Troxerutin (150 mg/kg/day) was gavaged in the CD + TRO and HFD + TRO groups during pregnancy. On the postnatal day (PND) 21 all female offspring were separated and fed CD until PND 90. On PND 90 animals were sacrificed and ovarian tissue samples were collected for further evaluation. RESULTS Results showed that HFD significantly decreased serum apelin-13 in the female offspring of the HFD dams, which was significantly reversed by TRO. Moreover, real-time polymerase chain reaction (PCR) analysis revealed that TRO treatment significantly decreased the ovarian mRNA expression of the apelin-13 receptor in the troxerutin-received offspring. Furthermore, histological examination revealed that TRO increased the number of atretic follicles in the ovaries of HFD+TRO offspring. CONCLUSION Maternal high fat feeding compromises ovarian health including follicular growth and development in the adult offspring and troxerutin treatment improved negative effects of maternal HFD on the apelin-13 level and ovarian development of offspring.

Abstract
Objective This study investigated the effects of the administration of ethanolic saffron petal extract (SPE) and vitamin E on growth performance, blood metabolites and antioxidant status in Baluchi lambs. Methods Thirty-two Baluchi male lambs (35.22±5.75 kg) were randomly divided into 4 groups. The 1st (control), 2nd (ISPE) and 3rd (Vit. E) groups were respectively injected subcutaneously with either physiological saline (5 ml), SPE (25 mg/kg BW) or DL-α-tocopheryl acetate (225 IU) once a week. An oral dose of SPE (500 mg/kg BW) was also administered to the 4th group (OSPE). Feed intake and body weight were measured for 42 days and blood samples were taken on days 1, 14, 28 and 42. The lambs were slaughtered and tissue samples were taken. Results Growth performance and many blood metabolites were not affected (p>0.05) by the treatments. Cholesterol of plasma in the ISPE and Vit. E groups was similar and less (p<0.01) than both the OSPE and control groups. Although there was no significant difference between the control and other groups for plasma triglyceride, the ISPE group showed lower (p<0.05) triglyceride than the OSPE and Vit. E groups. The highest (p<0.01) plasma glutathione peroxidase (GPx) was detected in the OSPE group, while the ISPE and Vit. E groups showed higher (p<0.01) superoxide dismutase (SOD) of plasma than the control. Malondialdehyde of plasma in the ISPE group was lower (p<0.05) than the OSPE. No differences (p>0.05) were observed among the groups for antioxidant status of both of the longissimus dorsi muscle and liver. However, the activity of GPx in the kidney and heart, as well as SOD activity in the kidney, were influenced (p≤0.01) by the treatments. Conclusion Adding ethanolic SPE improved antioxidant status and lowered lipids oxidation in lambs. The SPE and vitamin E demonstrated similar effects on antioxidant status in lambs.

Abstract
Aims The crucial role of the radial head in the stability of the elbow in terrible triad injury is acknowledged. This retrospective study aims to compare the results of resection of a severely comminuted radial head with or without prosthetic arthroplasty as part of the reconstruction for this injury. Patients and Methods The outcome of radial head resection was compared with prosthetic arthroplasty in 29 and 15 patients with terrible triad injuries, respectively. There were ten female patients (34.5%) in the resection group and six female patients (40%) in the prosthesis group. The mean age was 40.7 years (sd 13.6) in the resection group and 36 years (sd 9.4) in the prosthesis group. The mean follow-up of the patients was 24.4 months (sd 12) in the resection group and 45.8 months (sd 6.8) in the prosthesis group. Outcome measures included visual analogue scale (VAS) for pain, Mayo Elbow Performance Score (MEPS), Disabilities of Arm, Shoulder and Hand (DASH) Score, and range of movement. Postoperative radiological complications were also recorded. Results The mean ranges of extension, flexion, supination, and pronation were not significantly different between the two study groups (p = 0.75, p = 0.65, p = 0.82, and p = 0.68, respectively). The mean VAS score, DASH score, and MEPS of the two groups were also not statistically significantly different (p = 0.93, p = 0.19, and p = 0.32, respectively). At the final visit, the elbow was stable in all patients. No patient was found to have developed an Essex–Lopresti injury. Osteoarthritis grade I and II was observed in five and three patients of the resection group, respectively, and four and one patients of the arthroplasty group, respectively. Conclusion The outcome of patients undergoing treatment for terrible triad injuries is similar whether the patient’s radial head was excised or replaced.

Abstract
Objective: Glioblastoma (GBM) is the most malignant and aggressive type of glioma, associated with a high rate
of mortality. The transforming growth factor-β receptor II (TGFβ RII) is involved in glioma initiation and progression.
On the other hand, TGFβ RII silencing is critical to the inhibition of GBM. Therefore, we aimed to determine the
effects of specific TGFβ RII siRNA on the survival of U-373MG cells. Methods: TGFβ RII siRNA was transfected,
and qRT-PCR was performed to examine TGFβ RII mRNA expression. Cell survival was determined using colorimetric
MTT assay, and platelet-derived growth factor-BB (PDGF-BB) level was measured in the culture supernatant using
ELISA assay. Result: Our findings indicated that specific siRNAs could dose-dependently suppress TGFβ RII mRNA
expression after 48 hours. In addition, treatment with TGFβ RII siRNA significantly reduced tumor cell survival and
decreased the amount of PDGF-BB protein in the cell culture supernatant. Conclusion: Our results suggest that TGFβ
RII silencing can be a promising complementary treatment for glioma.

Abstract
Due to key role of inflammation in pathogenesis of type 2 diabetes mellitus (T2DM), aim of this study was evaluating the influance of regular swimming on serum levels of C-reactive protein (CRP), interlukin-6 (IL-6), tumor necrosis factor-α (TNF-α) in high-fat diet-induced diabetic rats. Fourty male Wistar rats were randomly divided into control, diabetic, exercise and diabetic-exercise groups (n = 10). Diabetes was induced by high-fat diet and streptozotocin (35 mg/kg, i.p.). In exercise groups, after induction of diabetes, animals were subjected to swimming (60 min/5 days a week) for 10 weeks. At the end of training, rats were anestatized and blood samples and pancreatic tissues were collected and used for evaluation of CRP, IL-6, TNF-α and pancreatic histopatholology. Our results showed significantly increase in lymphocytes, monocytes and decrease in neutrophils in diabetic rats (p < 0.01), which these parameters significantly reversed to control levels by induction of swimming (p < 0.01). In diabetic group, the levels of CRP, IL-6 and TNF-α increased (p < 0.01), and swimming decreased these factors significantly. Histopathological results of this study also showed that swimming can prevent damage induced by diabetes. The present study indicates that swim training is associated with improved inflammation and inflammatory mediators and pancreatic damage.

Abstract
α-hederin, a saponin that is a major constituent of English Ivy (Hedera helix) is effective in the treatment of asthma. In the present study, the effect of α-hederin on lung tissue pathology and the levels of the inflammatory mediators; IL-2 mRNA, IL-17 mRNA, and MicroRNAs (miRNA)-133a was evaluated in a rat ovalbumin (OVA)-sensitized model of asthma. Rats were divided randomly into control (C), OVA-sensitized (S), OVA-sensitized pretreated with the antioxidant, thymoquinone (3 mg/kg, S + TQ) or OVA-sensitized pretreated with α-hederin (0.02 mg/kg, S + AH) groups. Levels of IL-2 and IL-17 mRNA were higher in the OVA-sensitized group than controls while the level of miRNA-133a gene expression was lower. IL-2 mRNA and miRNA-133a gene expression in the S + TQ group was higher than in the control and OVA-sensitized groups while the level of IL-17 mRNA in the S + TQ group was lower than in the OVA-sensitized group. Pretreatment with α-hederin decreased IL-17 mRNA levels and increased miRNA-133a gene expression compared with OVA-sensitized animals. All pathological changes in pretreated groups were lower than the OVA-sensitized group. These results showed a beneficial effect of α-hederin in OVA-sensitized rats, suggesting that α-hederin affects the IL-2 and IL-17 secretion pathways, altering miRNA-133a expression.

Abstract
OBJECTIVE In previous studies the therapeutic effects of Nigella sativa have been demonstrated on asthmatic animals. In the present study, the preventive effect of single dose of alpha-hederin, its active constituent, has been evaluated on lung inflammation and some inflammatory mediators in lungs of ovalbumin sensitized rat in order to elicit its mechanism. MATERIALS AND METHODS Forty rats were randomly grouped in 4 groups; control (C), sensitized (S), sensitized pretreated groups with thymoquinone (3 mg/kg i.p., S+TQ) and alpha-hederin (0.02 mg/kg i.p., S+AH). Levels of IL-13 mRNA and miRNA-126 in lung tissue and its pathological changes in each group were assessed. RESULTS Elevated levels of miRNA-126, IL-13 mRNA and pathological changes were observed in the sensitized group compared to the control group (p<0.001 to p<0.05). All of these factors were significantly reduced in S+TQ and S+AH groups in comparison to S group (p<0.001 to p<0.05). Although alpha-hederin decreased the levels of miRNA-126, IL-13 mRNA and pathological changes in comparison with thymoquinone, the results were statistically not significant. CONCLUSION The results suggested that alpha-hederin had preventive effect on sensitized rats like thymoquinone. It may intervene in miRNA-126 expression, which consequently could interfere with IL-13 secretion pathway leading to a reduction in inflammatory responses.

Abstract
Environmental manipulation at early critical periods could have long-lasting effects. In spite of the great interest in the biological effects of the environmental condition so far, its long-lasting effects are less documented. This study looks at the enduring effects of rearing condition on tasks that measure affective responses and exploratory behavior in male Wistar rats. The animals were reared from weaning to adulthood in an enriched environment, standard laboratory condition, or isolated condition. Then, all rats were housed in standard laboratory cages to provide a common environment, and successively exposed to different tests between 0 and 11 weeks post-manipulation. The open field test indicated a more efficient exploratory behavior in the enriched group, and an enhanced spontaneous motor activity in both standard and isolated groups. In addition, rats reared in standard condition showed heightened motor activity in forced swimming test and elevated plus maze. Forced swimming test showed an antidepressive-like effect in the enriched environment group by increased climbing behavior. In respect to the anxiety behavior, environmental enrichment improved threat detection ability. It is concluded that rearing condition from weaning to adulthood has important and long-lasting effects on depressive- and anxiety-like and exploratory behaviors as well as motor activity.

Abstract
This study was designed to investigate the anti-arrhythmic effect of diosgenin preconditioning in myocardial reperfusion injury in rat, focusing on the involvement of the nitric oxide (NO) system and mitochondrial ATP-dependent potassium (mitoKATP) channels in this scenario. After isolation of the hearts of male Wister rats, the study was conducted in an isolated buffer-perfused heart model. Global ischemia (for 30 min) was induced by interruption of the aortic supply, which was followed by 90-min reperfusion. Throughout the experiment, the electrocardiograms of hearts were monitored using three golden surface electrodes connected to a data acquisition system. Arrhythmias were assessed based on the Lambeth convention and were categorized as number, duration and incidence of ventricular tachycardia (VT), ventricular fibrillation (VF), and premature ventricular complexes (PVC), and arrhythmic score. Additionally, lactate dehydrogenase (LDH) levels in coronary effluent were estimated colorimetrically. Diosgenin pre-administration for 20 min before ischemia reduced the LDH release into the coronary effluent, as compared with control hearts (P < 0.05). In addition, the diosgenin-receiving group showed a lower number of PVC, VT and VF, a reduced duration and incidence of VT and VF, and less severe arrhythmia at reperfusion phase, in comparison with controls. Blocking the mitoKATP channels using 5-hydroxydecanoate as well as inhibiting the NO system through prior administration of L-NAME significantly reduced the positive effects of diosgenin. Our finding showed that pre-administration of diosgenin could provide cardioprotection through anti-arrhythmic effects against ischemia-reperfusion (I/R) injury in isolated rat hearts. In addition, mitoKATP channels and NO system may be the key players in diosgenin-induced cardioprotective mechanisms.

Abstract
PURPOSE Hypoxia is a condition of decreased availability of oxygen. To adapt hypoxia, some changes in blood cells occur in the body. The aim of this study was to evaluate the effect of ghrelin on different types of blood cell in normobaric hypoxia situation. METHODS Thirty-two animals were divided in 4 groups (n=8): control (C), ghrelin (G), hypoxia (H), and hypoxic animals that received ghrelin (H+G). Hypoxia (11%) was induced by an Environmental Chamber System GO2 Altitude. Animals in ghrelin groups received a subcutaneous injection of ghrelin (150 μg/kg/day) for 14 days. RESULTS Our results show that ghrelin significantly (p<0.05) increased RBC and Hct levels, whereas it significantly (p<0.05) decreased lymphocytes in the blood. RBC, Hct, Hb concentration, platelet and MCV increased significantly (p<0.05) in hypoxic conditions but lymphocytes, monocytes and Polymorphonuclears did not show any significant changes. Platelets had a significant (p<0.05) decrease in hypoxic conditions and ghrelin administration in hypoxic conditions could increase lymphocyte levels significantly (p<0.05). CONCLUSION Effect of ghrelin on blood cells could be related to blood oxygen level. Ghrelin in normal oxygen conditions increases RBC and Hct levels but decreases lymphocytes, whereas in hypoxic conditions, ghrelin increases blood lymphocytes.

Abstract
Oral mucositis is a common and irritating complication of chemotherapy and radiotherapy for malignancies. Current treatments have failed to achieve complete remission of this complication. The St. John's wort plant (Hypericum perforatum) has long been known for its anti-inflammatory and antibacterial effects. The current study was designed to investigate the therapeutic efficacy of the topical and systemic administration of H. perforatum extract on oral mucositis. Oral mucositis was induced in 72 male golden hamsters by administration of 5-fluorouracil (60mg/kg), on days 0, 5, and 10 of the study. The cheek pouch was scratched with a sterile needle on days 1 and 2. On days 12-17, H. perforatum extract topical gel 10%, oral H. perforatum extract (300mg/kg), and gel base groups were treated and then compared with a control group. Weights and blood samples were evaluated, biopsies from buccal lesions were examined histopathologically, and tissue malondialdehyde (MDA) was measured. Both of the H. perforatum extract treatment groups saw a significant relief in oral mucositis compared to the control and base gel groups; the systemic form was superior to the topical form. H. perforatum extract, administered orally or topically, expedited the healing of chemotherapy-induced oral mucositis in hamsters.

Abstract
PURPOSE Ghrelin has been shown to have antiepileptic function. However, the underlying mechanisms by which, ghrelin exerts its antiepileptic effects are still unclear. In the present study; we investigated antiepileptic mechanism of ghrelin through GABAB receptors using CGP35348 (selective GABAB receptor antagonist). METHODS Male Wistar rats' hippocampi were bilaterally microinjected with the single dose or 10-day ghrelin (0.3 nmol/µl/side). CGP35348, GABAB receptor antagonist, (12.5 µg/µl/side) or saline injected into the dorsal hippocampus 20 minutes before ghrelin administration. Thirty min after ghrelin microinjection, a single convulsive dose of pentylenetetrazole (PTZ) (50 mg/kg) was injected intraperitoneally (i.p). Afterwards, seizure duration and total seizure score (TSS) were assessed for 30 minutes in all animals. RESULTS Our results demonstrated that acute and chronic intrahippocampal (i.h.) injection of ghrelin could significantly (p<0.001) attenuate the severity of seizures. Ghrelin 0.3 nmol/µl/side decreased duration of seizure significantly both in acute (p<0.001) and chronic (p<0.01) injections. The ghrelin antiepileptic effect was completely antagonized by GABAB blockade. The suppression of both duration and TSS induced by ghrelin in hippocampus was significantly (p<0.001) blocked by CGP35348 in PTZ-induced seizures. CONCLUSION In summary, our findings suggest that GABAB receptors may mediate the antiepileptic action of ghrelin in the hippocampus. Therefore, it is possible to speculate that ghrelin acts in the hippocampus to modulate seizures via GABA.

Abstract
PURPOSE Ghrelin has been shown to have antiepileptic function. However, the underlying mechanisms by which, ghrelin exerts its antiepileptic effects are still unclear. In the present study, we investigated whether neuropeptide Y (NPY) mediates ghrelin anticonvulsant effect in the brain through its Y1, Y2 or Y5 receptors. METHODS Male Wistar rats were bilaterally microinjected with ghrelin 0.3 nmol/μl/side and NPY antagonists; GR231118 (Y1 receptor antagonist), BIIE0246 (Y2 receptor antagonist), CGP71683 (Y5 receptor antagonist) or solvents (Saline, DMSO) into the dorsal hippocampus 20 minutes before ghrelin administration. Thirty minutes after ghrelin microinjection, a single convulsive dose of pentylenetetrazole (PTZ) (50 mg/kg) was injected intraperitoneally (ip). Afterwards, duration of seizure and total seizure score (TSS) were assessed for 30 minutes in all animals. RESULTS Intrahippocampal injection of 0.3 nmol/μl/side ghrelin decreased duration of seizure and TSS induced by PTZ. The suppression of both duration (p<0.001) and TSS (p<0.001) induced by ghrelin in hippocampus were significantly blocked by GR231118 (10 μg/μl/side), BIIE0246 (400 pmol/μl/side) and CGP 71683A (5 nmol/μl/side). CONCLUSION Our findings suggest that NPY Y1, Y2 and Y5 receptors in the hippocampus may somehow mediate the anticonvulsive action of ghrelin. Therefore, it is possible to speculate that ghrelin acts in the hippocampus to modulate seizures via NPY.

Abstract
OBJECTIVE OF THE STUDY Candidiasis is an opportunistic fungal infection caused by many species of Candida that affects different sites of the body. Secretion of exoenzymes plays an important role in virulence and pathogenesis. The aim of this study was to evaluate the potential role of phospholipase, esterase and hemolytic activity of Candida species isolated from onychomycosis and oral lichen planus patients in candidiasis. METHODS A total of 84 Candida isolates including 24 C. albicans and 46 C. parapsilosis from onychomycosis, and 14 C. albicans from oral lichen planus patients were included in our study. Egg yolk agar, Tween 80 opacity medium and blood agar plate assays were used for determining phospholipase, esterase and hemolytic activities, respectively. Statistical analyses were performed using the Fischer exact test. RESULTS C. parapsilosis isolates had the least exoenzyme activity among the isolates (P≤0.001). C. albicans isolates from lichen planus showed less exoenzyme activity in comparison to the onychomycosis isolates. Only 16.08% of C. parapsilosis isolates had phospholipase activity. This difference between C. albicans and C. parapsilosis was statistically significant (P≤0.001). All of the C. albicans isolates from onychomycosis patients had beta hemolysin activity. There was more hemolytic activity in the C. albicans isolates when compared with C. parapsilosis and between C. albicans isolates, no significant difference was seen. All of the C. albicans isolates produced esterase enzyme on day three and no significant differences were seen between the two groups of C. albicans for esterase activity. Two strains of C. albicans had no phospholipase or esterase activity. CONCLUSION This study showed that most of the isolates tested had different enzymatic patterns and C. parapsilosis strains had less phospholipase activity.

Abstract
Hypoxia is an important pathogenic factor for the induction of vascular leakage and brain edema formation. Recent studies suggest a role for TNF-α in the induction of brain edema. Ghrelin attenuates the synthesis of TNF-α following subarachnoid hemorrhage and traumatic brain injury (TBI). Therefore, we examined the effects of ghrelin on the brain edema, serum TNF-α levels and body weight in a systemic hypoxia model. Adult male Wistar rats were divided into acute and chronic controls, acute or chronic hypoxia and ghrelin-treated (80μg/kg/ip/daily) acute or chronic hypoxia groups. Systemic hypoxia was induced in rats by a normobaric hypoxic chamber (O(2) 11%) for two days (acute) or ten days (chronic). Effect of ghrelin on brain edema and serum TNF-α levels was assessed by dry-wet and ELISA method, respectively. The results showed that acute (P<0.001) and chronic (P<0.05) hypoxia caused an increase of brain water content. Administration of ghrelin only in the acute hypoxia group significantly (P<0.001) reduced brain water content. Acute hypoxia caused an increase of serum TNF-α level (P<0.001) and ghrelin significantly (P<0.001) reduced it. TNF-α level in chronic hypoxia did not change significantly. Both acute and chronic hypoxia decreased body weight significantly (P<0.001) and administration of ghrelin only could prevent further weight loss in chronic hypoxia group (P<0.001). Our findings show that administration of ghrelin may be useful in reducing brain edema induced by acute systemic hypoxia and at least part of the anti-edematous effects of ghrelin is due to decrease of serum TNF-α levels.

Abstract
INTRODUCTION Alzheimer's disease (AD) is a common neurodegenerative disorder in elderly people with an impairment of cognitive decline and memory loss. β-amyloid (Aβ) as a potent neurotoxic peptide has a pivotal role in the pathogenesis of AD. This disease begins with impairment in synaptic functions before developing into later neuro¬degeneration and neuronal loss. The aim of this study was to evaluate the synaptic plasticity and electrophysiological function of granule cells in hippocampal dentate gyrus (DG) after intracerebroventricular (i.c.v.) administration of aggregated Aβ (1-42) peptide in vivo. METHODS Animals were divided to control and Aβ (1-42) groups. Long-term potentia¬tion (LTP) in perforant path-DG synapses was assessed in order to investigate the effect of aggregated Aβ (1-42) on synaptic plasticity. Field excitatory post-synaptic potential (fEPSP) slope and population spike (PS) amplitude were measured. RESULTS Administration of Aβ (1-42) significantly decreased fEPSP slope and PS amplitude in Aβ (1-42) group comparing with the control group and had no effect on baseline activity of neurons. CONCLUSION The present study indicates that administration of aggregated form of Aβ (1-42) into the lateral ventricle effectively inhibits LTP in granular cells of the DG in hippocampus in vivo.

Abstract
BACKGROUND Recurrent aphthous stomatitis (RAS) appears to be the most common type of oral ulcers. The lesion is usually self limited but its painful presentation results in some difficulties. Therefore, an efficient therapeutic strategy is required and currently existing therapies seem to be inadequate because of its unclear etiology. Here the therapeutic effect of triamcinolone acetonide ointment as a relatively expensive medication has been compared with phenytoin syrup on aphthous ulcers in patients with Behcet's syndrome. METHODS Thirty out of 60 our patients with Behcet's syndrome were randomly treated by phenytoin syrup and the remaining were advised to use 0.1% triamcinolone acetonide ointment. After a week, they were visited again to determine the status of aphthous ulcers. RESULT Positive response in the triamcinolone acetonide group and phenytoin group was 86.7% and 53.3%, respectively. CONCLUSION The effectiveness of triamcinolone acetonide ointment was more than phenytoin on aphthous ulcers in patients with Behcet's syndrome.

Abstract
OBJECTIVE this study designed to test the antibacterial potency of enrofloxacin (ENR) and essential oils from Zataria multiflora Boiss (ZEO) and Trachyspermum copticum (TEO) on Aeromonas hydrophila. MATERIAL AND METHODS The antibacterial potency of test compounds was determined by several methods including the inhibition zone diameter determination, microbroth dilution method and colorimetric method of MTT. The cytotoxicity of test substances was assessed on Chinook salmon (Oncorhynchus tshawytscha) embryo (CHSE-214) cells. RESULTS RESULTS showed that ENR and tested essential oils exert antibacterial effect against A. hydrophila. Moreover, ENR exerted the most potent antibacterial effect with MIC values of 62.5 ng/ml. The natural compounds of ZEO and TEO also showed antibacterial effects with rather high MIC values of 0.315 mg/ml, and 1.25 mg/ml, respectively. None of the tested substances showed toxicity on CHSE-24 cells. CONCLUSION It is concluded that ZEO and TEO could be applied to prevent from A. hydrophila infection. Moreover, data also suggest that MTT method could be both cost- and time-effective and accurate method of MIC determination.

Abstract
BACKGROUND The interaction of diabetes with cardioprotection by postconditioning in ischemia/reperfusion injury remains unclear. The aim of this study was to investigate the concomitant effects of ischemic postconditioning (IPostC) and cyclosporine-A (CsA) on nitric oxide (NO) content and parameters of cardiac function of the diabetic myocardium injured by ischemia/reperfusion. METHODS Diabetes was induced by single injection of streptozotocin (50 mg/kg; intraperitoneally [ip]) in Wistar rats (250-320 g) and the diabetic period was 8 weeks. The hearts (n = 96) were removed quickly, mounted on Langendorff apparatus, and then subjected to 30-minute regional ischemia followed by 45-minute reperfusion. Ischemic postconditioning was induced by 3 cycles of 30-second reperfusion/ischemia at the onset of reperfusion. Myocardial function was measured throughout the experiment, and infarct size (IS) was identified by triphenyltetrazolium chloride (TTC) staining. Total amounts of NO metabolites were determined using Griess method and enzyme-linked immunosorbent assay (ELISA) reader. RESULTS Administration of either IPostC or CsA alone in nondiabetic animals significantly improved myocardial function and reduced the ISs (28% ± 1.9% or 23% ± 2.0% vs 41% ± 2.9% of the risk zone [RZ], respectively; P < .01), but they had no effect on diabetic hearts (35% ± 1.8% or 32% ± 2.1% vs 39% ± 3.1%, respectively). In addition, myocardial NO level was significantly increased by IPostC only in nondiabetic animals (P < .01). However, after administration of CsA (5 minutes before and 10 minutes after the onset of reperfusion) in postconditioned animals, the cardioprotective and NO-enhancing effects of IPostC were restored in diabetic rats (IS: 21% ± 1.1% vs 39% ± 3.1%), similar to those in nondiabetic controls (19% ± 1.3% vs 41% ± 2.9%; P < .01). CONCLUSION The present study indicated that IPostC or CsA failed to affect NO levels and failed to protect the diabetic myocardium against ischemia/reperfusion injury. Moreover, concomitant administration of CsA and IPostC at reperfusion can increase NO content and protect the diabetic myocardium.

Abstract
AIM Epilepsy is one of the most common neurologic problems worldwide. A relationship between epilepsy and hormones has been demonstrated. This study was designed to investigate the effect of seizure on blood ghrelin level. METHODS Twenty male Wistar rats were divided into two groups. The control group received saline and the pentylenetetrazole (PTZ) group received a single convulsive dose (50mg/kg) of PTZ. Thirty minutes later blood samples were collected and acylated and unacylated ghrelin levels in the plasma were assayed. RESULTS Acylated or active form of ghrelin decreased significantly (p<0.05) after a PTZ-induced seizure, but the reduction of unacylated and total blood ghrelin levels failed to reach statistical significance. CONCLUSION These findings may reflect that PTZ-induced epilepsy decreases AG of plasma.

Abstract
BACKGROUND Needlestick injuries (NSIs) are among the most important occupational injuries for health care workers (HCWs). In Iran, the problem of exposure to contaminated blood among nursing personnels has not well documented. The aim of this study was to determine the incidence of needlestick injuries in population of nurses in Shahroud Imam Hossein Hospital, northern Iran. METHODS A self-administrated questionnaire was completed by 180 nurses in September and October 2005 for their NSIs experience in the past year. In this study, needlestick injury was defined as percutaneous injury caused by hollow-borne needles, suturing needles, scalpel blades and lancets. RESULTS The case incidence of NSIs was 63.3% (114/180). The total number of episodes of NSIs among respondents was 220 (range: 1-5 episodes) with incidence rate of episodes i.e. 1.2 per person/year. 12.8% of nurses had not been vaccinated against hepatitis B virus (HBV). The causal devices in 105 cases (92.1%) were hollow-borne needles and the main causes of percutaneous injuries with hollow-bore needles were recapping (32.4%) and manipulating needles in patients (18.1%). The majority (51.8%) of injuries occurred after use and before disposal of the objects. CONCLUSION Nurses working in Imam Hossein Hospital are frequently exposed to blood-borne infection. NSIs were highly prevalent in these nurses therefore more intensive education programs should be directed at nurses to increase their awareness of and compliance with universal precautions (UP). We recommend a surveillance system and a center for managing injured persons.
