Abstract
Background & Objectives: The incidence of neonatal hyperbilirubinemia disease is noticeable. Studying neonatal hyperbilirubinemia and its related factors is a step to reduce its incidence and remarkable treatment expenses. On the other hand, due to lack of on time recognition and suitable treatments, this disease can cause irreversible neuro-cerebral complications. This study was conducted to examine the etiology of neonatal hyperbilirubinemia and its associated signs, in order to provide on time and suitable treatment measures.
Methods: This cross-sectional study was performed in 2003 on neonates affected by neonatal hyperbilirubinemia in Ardabil Sabalan hospital. The data obtained from their conditions, clinical examination, and measurment of total and direct bilirubine was used to fill out a questionnaire. The data were analyzed by SPSS software (release 10).
Results: From among 132 neonates affected by neonatal hyperbilirubinemia, 50% were male and others were female. 85.6% of these subjects were fullterm births and the rest were premature. 56% of these neonates were born by C/S. 6.8% of hyperbilirubinemia cases, which were considered as “pathologic”, occurred during 24 hours after birth. 72% were related to the second to seventh days of birth, 17.2% to second week of birth, and the rest (4%) had prolonged Icter. 65% of these neonates were the first children of the family. The average time of hospitalization was 4.8 days. 34.8% of these neonates had pathologic signs beside hyperbilirubinemia and had a clinically serious condition. About 23% of these neonates were born by C/S and only 11.8% of them were vaginal births. 46 cases (34.8%) had accompaynig pathologic problems in addition to Icter, among whom 33 children (25%) had evident infection. The causes of hyperbilirubinemia were Crigler-Najjar syndrome in one case, ABO in 11 cases (8.33%) and RH discord in 4 cases (2.8%). Generally speaking the precise cause of 36.89% of Hyperbilirubinemia was determined.
Conclusion: Some factors such as children by C/S, neonatal infection, prematurity, ABO discords and RH discords play an important role in hyperbilirubinemia incidence and severity.

Abstract
Background & Objectives: Benign prostatic hyperplasia is one of the most common diseases in males and Transurethral Resection of Prostate (TUR-P) is a standard method for its surgery. Distilled water is used to clean the field of operation from blood and debris. The overabsorption of this washing fluid can lead to hemodynamic disorders and neurological complications called TUR-P syndrome. Because of hemolysis and ATN, most of the urologists, nowadays, prefer to use non-hemolytic solutions such as cytol and glycine 1.5%. Distilled water is widely used in Iran. Replacing this water with a nonhemolytic and hypoosmolar solution with reasonable price such as manitol 3% seems reasonable. This study was carried out to campare manitol 3% with distilled water during TUR-P. Methods: In a double-blind randomized clinical trial, we studied 78 patients with BPH who were admitted to Shahid Moddares hospital in Tehran for TUR-P. These patients were allocated to disstiled water group and manitol 3% group. Na, K, Cr, BUN, CBC, U/A, U/C, 24 hr urine volume and creatinine were checked preoperatively to determine GFR, Na, K, BUN and CBC were checked right after, 4 hours after and on the morning after the operation. Clinical signs of TUR-P syndrome were recorded in the patients as bradycardia, hypertension and neurologic sign. Results : Mean age was 68.6 in distilled water group and 66.4 in the manitol group. Mean weight of resected tissues, mean volume of the solution used and mean resection time were 19.8 gr, 19 litre, 50.8 minutes respectively in distilled water group and 20.2 gr, 20.3 litre and 51 minutes in the manitol 3% group. These differences were not statistically significant. The difference between decrease in serum Na and serum osmolality was not significant in two groups, however, hemolysis rate in two groups was statistically significant (p<0.01). The incidence rate of TUR-P syndrome was 34% in the distilled water group and 18% in manitol group. This difference was not statistically significant. Postoperative creatinine increase was 0.625 mg/dl in distilled water group and 0.04 mg/dl in manitol group. This was not statistically significant. Conclusion: Regarding the role of distilled water in hemolysis and ATN and due to the unavailability of non – hemolytic solutions such as glycine and cytol in Iran, the use of manitol 3% soluion which is a cost-effective, non hemolytic and hypoosmolar solution is recommended.

Abstract
Background & Objectives: The ischemic stroke is defined as cerebral dysfunction due to brain infarct which is induced by vascular obstruction. The related risk factors including hypertension, diabetes mellitus, cardioembolism and hyperlipidemia are investigated in several studies. The aim of this study was to determine the etiology of cerebral infarction in young adults ( - year-olds). Methods: All the patients in the age rang of - admitted to the neurology ward of Alavi Hospital in Ardabil between 2004 and 2005 with a diagnosis of cerebral infarction were included in this study. A questionnaire including demographic data, personal and family history of stroke and cardiac infarct, hypertension, diabetes, smoking and hyperlipidemia was filled out for all patients. Blood sugar, cholesterol, anticardiolipin antibody and beta- glycoprotein were examined. The patients underwent echocardiography. The data were analyzed using SPSS software (release ). Results: The total number of the patients was , including females (71.1%) and males (28.9%). The mean age was (SD= ). The etiologic factors based on their frequency were: cardioembolism ( ), positive antiphospholipid antibodies (35.5%), hyperlipidemla ( ), smoking ( ), hypertension ( ), oral contraceptive use ( ) and diabetes mellitus (13.7%). Conclusion: The most frequent etiologies of the cerebral infarcts in the young adults in this study were cardiogenic embolism and positive antiphospholipid antibodies. Other background factors were hyperlipidemia, smoking, hypertension, oral contraceptive use and diabetes mellitus respectively. Most of these etiologies can be intervened and prevented. The identification of these factors before occurrence of cerebral infarction can prevent this debilitating event.

Abstract
Background & Objective: Visceral leishmaniasis is a reticulo endothelia system and it is known as 'black fever' by Indians. According to WHO every year there are 500 thousand new cases of it in the world. The province of Ardabil, with 25-40% from all the country's leishmaniasis has a major part in the country and is considered as one of the main focuses in Iran. Due to its importance, this study was done to identify clinical signs and demographic characteristics of the patients. Methods: This was a descriptive cross-sectional study which was done retrospectively 110 children who were hospitalized in three different active hospitals between 1375-1382 entered in this study. Disease definition include parasite detection in bone marrow aspivation or special clinical signs (fever, spleenomegal, pansytopenia and weight loss) in addition direct agglutination test was positive. The samples were investigated in terms of demographic information. Place of living, clinical signs and the length of time between the symptoms of the disease and its diagnosis. To get to the results, simple descriptive statistics was used. 37.8% of the patients were diagnosed from the beginning of symptoms with in a month. Results: There were 56.4% boys and 43.6% girls of all the 110 children. DAT test was done in 97 patients which was positive in 91 cases (minimum positive titer 1/400). In 42 patients biopsy and bone marrow aspiration was done which was positive in 26 cases (lishman body detection). The age of the patients was 4 months -14 years. The most common findings were fever 97.3% and anorexia 97.1%. There was anemia in 90% thrombocytopenia in 60.8% and leukopenia in 24.8%. There was death in 6 patients (5.5%) and unresponsiveness to the treatment in 3 cases (2.7%). Conclusion: The results of the present study nearly corresponds to those of other studies. The main vulnerable community of visceral lieshmaniasis are mainly children. In order to decrease the mortality and morbidity its early diagnosis is essential. It is necessary that the physicians working in endemic regions be familiar enough with the disease.

Abstract
Background & Objectives: The high incidence of low birth weight (LBW) occurs in developing countries, and diarrhea and respiratory infections are the main causes of infant mortality and morbidity. This study was done to find out whether there was a growth or morbidity response to zinc supplememttion, among LBW infants during the first 6 mo of life. Methods: The study was a randomized, placebo-controlled, and double-blind trial study. LBW infants were given daily for 6mo 5mg zn, or a placebo. Questionnairs were filled out during the study by a pediatrician and a GP. Anthropometric measurements were made at 0, 4, 8, 12, 16, 20 and 24 wk via home visits by trained interviewers. Results: Baseline characteristics were similar in zinc and placebo groups. Weight gain in zinc group was significantly higher that of placebo group between 1 to 6 months (p=0.036). Length and head circumference gain were also greater in zinc group than in placebo groups, (p=0.04, p<0.001). The episodes of upper respiratory infections was greater in placebo group than zinc group (mean Episodes in zinc groups= 1.7 and in placebo group was 3) and there was significant difference between two groups (p=0.005). 8 Cases of lower respiratory infections in placebo group and 5 cases in zinc group were observed, but it was not significan diarrheal episods were observed only in placebo groups. Conclusion: It was found that low birth weight infants had better growth and lower morbidity during the first 6 months of life by receiving zinc supplementation.

Abstract
Background & Objectives: One of the most common gastrointestinal diseases is gallstone and its complications, that leads to hospitalization and expensive cost. Since Causative factors in this disease are so many that some of them can be preventable and there has not been a study on the risk factor and gallstone, this study investigates the relationship between riskfactor and gallstone, Methods: This was a case-control. study A total of 150 patients with gallstone using the simple nonrandomized method were selected and were compared with 150 hospital controls with which they were matched. The risk factors for gallstone formation (age, gender, family history, parity, obesity, diabetes mellitus, hyperlipidemia) were assessed in all of subjects. The association of gallstone with all these risk factor was evaluated with statistical tests including chi-square, ANOVA. Results: In this study, 117 cases (78%) were female and the other 33 cases (22%) were male. 42 persons (28%) were between 40-49 years old and about body mass index 63 persons (42%) were at the range of 25-299 (overweight). The mean serum level of triglyceride in women of case-group was 152.7 ± 7.5 in comparison with 117.8 ± 57.7 mg/dl in control group (p=0.001). Mean duration of oral contraceptive pills in case was 6.9 ± 4.9 in comparison with 3.1 ± 2.9 years in control group. There was a positive correlation between Goldstone, BMI and mean serum trighyceridz level in women (p=0.001, p=0.001). There was not any arelationship between the parity, smoking, hyper chlostrolemia, hypertriglyceride (in men), positive family history and gallstone. Conclusion: In this study, bidy mas index, the period of taking oral contraceptive pills and triglyceride play roles in gallstone formation. Since these factors can be interventional, it is essential that good plannings be devised to improve them.

Abstract
Background & Objective: Cerebrovascular disease mortality rates have declined in some countries during recent decades. Changes in mortality rates over time could be attributed to changes in disease incidence or case fatality rate. Very few studies have provided information regarding survival after stroke. We aimed to determine the case-fatality rate (28 days) among patients with first-ever stroke from a population-based study in Ardabil province, Northwest of Iran. Methods: This study was conducted between May 2005 and February 2006, all individuals with an acute stroke who were residents in Ardabil province and hospitalized at Alavi Hospital, were registered prospectively and assessed according to standardized diagnostic criteria. The data were analyzed through SPSS, Chi square and variance analysis. Results: A total of 352 patients with first-ever stroke were registered, and 346 (96%) were followed up. 288 (81.8%) ischemic stroke, 16.2% (57) ICH and 2% SAH. By 28 days, 70 patients (20.3%) had died. Hypertension, diabetes and cardiac disease history were reported in 61.6%, 16.8% and 26.1% respectively and 19.8% of patients were smokers. Mean age of survivors was different from patients who died at 28 days after index event (64.2±12.9 VS 69.1±10.9, p=0.03). The proportion surviving 28 days varied from 16.2% among patients with ischemic stroke to 43% among ICH and SAH. For ischemic stroke, Survival rates were similar for men and women, whereas men with ICH had lower survival than women. Conclusion: Case fatality rate after first-ever stroke is substantial. Rates of mortality differ according to patients diagnosis, age, sex, and heart disease. These data highlight the importance of long-term secondary prevention.

Abstract
Background & Objectives: hyperphosphatemia and hyperkalemia have major roles of mortality and morbidity in hemodialysis patients. In this study we evaluated the effectiveness of increase in blood flow rate on blood potassium and phosphate of hemodialysis patients.
Methods: This is a clinical trial study 42 patients were assessed during the hemodialysis. A questionnaire and laboratory tests were used for gathering data. At first questionnaire of demographic data was completed and then the weight of patients was connected to each session of dialysis. Then the patient was connected to dialysis machine and blood sample was gathered before dialyzer. After taking blood sample, flow rate was regulated on 200 ml/min in the first session and on 250 ml/min in the next session. During hemodialysis, hemodynamic status and clinical status of patients was controlled. At the end of hemodialysis and before disconnection patient from dialysis machine, a blood sample was taken from arterial set before dialyzer (4 blood samples for each patient). Blood sample was sent to laboratory and all of them were analyzed by one technician and with one set.
Results: Average phosphorus changed significantly from 3.35 to 2.94 with increasing Qb from 200 to 250 similar to the increase in Qb in potassium removal (from 3.43 to 3.52) meq/lit. Paired t-test (p0.005).
Conclusion: It can be concluded so that increase in blood flow rate from 200ml/min to 250ml/min, can affect removal phosphorus but can not affect removal of potassium

Abstract
Background & Objectives: Diabetes Mellitus is a metabolic disorder in which lacking of control and suitable care lead to disability and mortality. American Diabetes Association (ADA) has emphasized the medical care of diabetic patients and has suggested several objectives to increase survival and improve health outcomes with low complications by controlling the glycemic, lipids, nerupathy and hypertension as well as foot care, nutritional therapy and screening of cardiovascular disease. The aim of this study was to evaluate the quality of care in diabetic patients from Ardabil and its concordance to the standards recommended by ADA. Methods: In a cross sectional study, 100 diabetic patients referring to a clinic of diabetes in Ardabil (2005) were randomly selected and enrolled. The study was conducted according to a questionnaire with 90 questions and physical examination and Final lab tests. Data were collected and analyzed with Spss version 12. ANOVA test was used to compare groups. Results: The 12 months recorded lab tests for diabetic patients were as follows: Hb A1C in 33%, MicroAlbuminuria in 16%, HDL in 58% and LDL in 55% of patients had been checked. Foot and peripheral pulses exams were only recorded in 9 and 5% of patients respectively. In final lab tests, 24% of patients had favorable FBS level (90- 130mg/dl). 46% of patients had suitable Hb A1C and 32% patients had MicroAlbuminuria. Aspirin was recommended to 45% of patients over 50 years old. Only 10% of patient for three lab tests (FBS, LDL cholesterol, Hb A1C) achieved the intended aims. According to ADA recommendations 22% of patients for three risk factors (BP, LDL cholesterol & Total cholesterol) were in optimal level. Conclusion: There is a high difference between current diabetes care in our clinic and ADA goals.

Abstract
Background & objectives: Micro-RNAs are non-coding RNAs with a length of approximately 22 nucleotides, which, by binding to the target gene's mRNA, regulate its expression and play an important role in tumor suppression. Changes in the expression level of microRNAs play a crucial role in the pathobiology of multiple cancers. In this study, the expression levels of miR-143 and miR-338 were compared in gastric cancer and its margin.
Methods: This case-control study was performed on 35 biopsy samples of gastric cancer and adjacent tissue of the patients who were admitted to Imam Reza Hospital. Total RNA was extracted from the tissue using Trizol reagent and based on the company's instructions. Then, the acquired microRNAs were used to synthetize cDNA. Expression of microRNAs was measured by RT-PCR. U6 was used as a house keeping gene. Statistically, the obtained results were analyzed using Graph pad Prism software.
Results: According to the results obtained in this study, the expression levels of miR-143 (p≤0.1244) and miR-338 (p≤0.0059) in tumor tissue, compared to the adjacent tissue, were down-regulated. Reduced expression of miR-143 and miR-338 in the tumor tissue, in comparison to margin tissue, was about four folds.
Conclusion: This study showed that the average expression level of miR-143 and miR-338 was significantly decreased in gastric cancer tissues compared to adjacent non-tumor tissues, and these results strongly suggest that miR-143 and miR-338 may play a key role in gastric cancer progression; therefore, they may be considered tumor markers.

Abstract
Background & objectives: Irisin is a novel myokine that encoded by FNDC5 gene and effects on obesity, metabolism and glucose homeostasis through browning of white adipose tissue and thermogenesis. The main purpose of this study was to investigate the changes of FNDC5 gene expression and Irisin protein level of visceral fat tissue after eight weeks of resistance training in type 2 diabetic rats.
Methods: Eighteen male Wistar rats (8 week old) were used for this study. Diabetes was induced using nicotinamide and streptozotocin . Five days after inducing diabetes, rats with fasting blood glucose levels between 127-600 mg / dl were selected as diabetic subjects. Rats were homogenized according to the body weight and assigned into two groups including control-diabetes (n=9) and resistance training-diabetes (n=9). Training group exercised resistance training for eight weeks (5 days a week). The resistance training protocol consisted of climbing a one-meter- high ladder, with a weight attached to a tail sleeve. Quantitative Real time RT-PCR and ELISA Kit were used for assessment of expression level of FNDC5 gene and Irisin protein, respectively. Data were analyzed using independent t- test at p≤0.05.
Results: Resistance training significantly increased the expression level of FNDC5 gene and Irisin protein in visceral adipose tissue in type 2 diabetic rats.
Conclusion: It seems that FNDC5 gene and Irisin protein have an important role in metabolic diseases and can be affected by resistance training. Perhaps the changes in the levels of these metabolic indicators is a potential new target for the treatment of metabolic disorders, such as T2DM (type 2 diabetes).

Abstract
Background & objectives: Shigella species are one of the most common causes of dysentery and sometimes death, especially in children and those with immunodeficiency. The variety of causative agents (Shigella species) and the development of drug-resistant strains make it difficult to select an appropriate antibiotic for the treatment of shigellosis. One of the most important factors involved in the resistance of Shigella isolates is the presence of extended spectrum beta lactamases (ESBLs) genes. The aim of this study was to determine the frequency of blaPER, blaGES and blaVEB genes in Shigella sonnei isolated from patients with dysentery using multiplex-PCR method and to determine the antibiotic susceptibility patterns of these isolates.
Methods: A total of 60 isolates of Shigella sonnei were collected from different hospitals and medical diagnostic laboratories in Kerman province. Specimens from different age groups were cultivated in special media and confirmed by biochemical tests. The presence of blaPER, blaGES and blaVEB genes were investigated using specific primers and multiplex-PCR method. Antibiotic susceptibility test was performed by disc diffusion method based on CLSI standards.
Results: Multiplex-PCR results showed three samples had blaPER gene, but none of them had blaVEB or blaGES genes. Also, the results of antibiotic susceptibility test showed the highest resistance for amoxicillin- clavulanic acid (53.3%) antibiotic and the highest sensitivity for tetracycline (85%) antibiotic.
Conclusions: The results of the experiments indicated the presence of blaPER gene in Shigella sonnei isolates. In addition, the results showed high resistance of isolates to amoxicillin clavulanic acid and ceftriaxone antibiotics. Therefore, careful medical care and proper and timely use of appropriate antibiotics are essential to prevent the spread of resistant isolates.

Abstract
Background & objectives: Staphylococci are considered as one of the most important etiological agents of omphalitis. Due to the importance of early diagnosis of omphalitis in newborns, this infection can be diagnosed by novel techniques such as multiplex PCR which is rapid, cost- effective and more accurate than microbial culture. The aim of this study was to determine the frequency of Staphylococcus aureus, S. epidermidis and S.hominis species in umbilical cord infection in newborns.
Methods: In the present study, 45 umbilical cord samples were collected from Shahid Afzali pour hospital in Kerman, Iran. Followed by DNA extraction, Multiplex PCR reactions were performed using specific 16srDNA primers for S. aureus, S. epidermidis and S.hominis. Finally, PCR products were analyzed using electrophoresis and sequencing. Also, microbiological and biochemical differentiation tests were performed for the diagnosis of Staphylococci on all specimens.
Results: Amplification of 16srRNA genes for S. aureus, S. epidermidis, and S. hominis using Multiplex PCR demonstrated that the frequency of S. epidermidis ,S. aureus and S.hominis were 4.4%, 6.6% and 2.2% in the studied samples, respectively. The prevalence of staphylococcal isolates using differential tests was shown to be 33.3%.
Conclusion: This study indicated that, Multiplex PCR is a proper method for simultaneous identification of S. aureus, S. epidermidis and S.hominis species. Also, Staphylococci can be considered as a significant cause of umbilical cord infection in newborns. However, further studies urgently are needed to confirm this finding.

Abstract
Background & objectives: Trichostrongylus spp. are common parasites of herbivorous animals and trichostrongyliasis is an important zoonotic disease in Iran, especially in northern Iran. Routine laboratory methods for diagnosis of these infections are direct smear and formalin-ethyl acetate techniques. There is no enough evidence about the sensitivity of nutrient agar plate culture for detection of Trichostrongylus spp infections. The objective of this study was to compare the nutrient agar plate culture and the formalin-ethyl acetate sedimentation techniques for laboratory diagnosis of human trichostrongyliasis in an endemic area of northern Iran.
Methods: A total of 1553 fresh stool samples were collected from residents of 31 villages within the Fouman district in Guilan province during 2015–2016. All samples were examined using nutrient agar plate culture and formalin- ethyl acetate concentration techniques for detection of Trichostrongylus spp. infections.
Results: Overall, 71 cases were diagnosed with Trichostrongylus spp. by at least one of the methods. Considering parasitological results as the diagnostic gold standard, the sensitivity and specificity of nutrient agar plate culture were 90.1% and 100%, respectively. Also, the sensitivity and specificity of the formalin ethyl acetate concentration method were 95.8% and 100%, respectively.
Conclusions: According to the results of this study, the formalin ethyl acetate method is more sensitive than nutrient agar plate culture in the diagnosis of human trichostrongyliasis, especially in humid climate regions such as North of Iran.

Abstract
Background & objectives: Lipocalin family proteins, have been identified as adipokines associated with obesity, type 2 diabetes (T2D) and the metabolic syndrome. Exercise training and active compounds of plants have potency as antidiabetic that can be used for treating T2D. We have evaluated the effect of exercise training and Momordica chianti L. on Retinol binding protein-4(RBP4), Fatty acid binding proteins-4 (FABP4) and Lipocalin-2 (LCN2) in Men with T2D.
Methods: In this clinical trial study, 36 T2D men in Tehran were selected and randomly divided into four groups (control, M. charantia, training and M. charantia+training). The training groups participated in a progressive aerobic training for eight weeks, three sessions per week (40% to 70% of the reserved heart rate for 15 to 45 min). The groups of M. charantia and M. charantia+training received 2000 mg of M. charantia for eight weeks (twice a day before breakfast and dinner). Two days before and after the protocol, blood samples were taken in fasting state. Data were analyzed using Independent t test and ANOVA at p<0.05.
Results: The results showed that the RBP4, FABP4 and LCN2 decreased significantly in the experimental groups (p<0.0001). Also, RBP4, FABP4 and LCN2 levels were significantly decreased in the M. charantia+ training group compared to training and M. charantia groups (p<0.05).
Conclusions: Aerobic training and M. charantia may decrease inflammation in T2D patients by decreasing lipocalins. Furthermore, aerobic training along with M. charantia had a better effect.

Abstract
Background & objectives: The deposition of amyloid beta (Aβ) peptide in the brain is one of the most important features of Alzheimer's disease. In addition to memory loss, Aβ can lead to depression behavior. Alpha-pinene is a type of monoterpene that has antioxidant, anti-inflammatory, and neuroprotective effects. Here, by using an animal model for Alzheimer's disease, we investigated the effect of alpha-pinene on neuronal cell death in the hippocampus and depression induced by Aβ1-42.
Methods: Male Wistar rats weighing 240-260 g were divided into four groups including control, alpha-pinene, Aβ, and Aβ-alpha-pinene. Rats were placed in stereotaxic surgery apparatus and Aβ1-42 was injected into the hippocampus (4 µg per side) and alpha-pinene was treated intraperitoneally (50 mg/kg) for 14 consecutive days. At the end of the course, the level of depression was assessed using the forced swimming test. The animals' hippocampus was also examined microscopically after Nissl staining.
Results: Intra-hippocampal injection of Aβ1-42 increased the total immobility time in the forced swimming test (p<0.01), decreased the number of pyramidal neurons in the CA1 area (p<0.001), and reduced the thickness of the neuronal layer in this region of the hippocampus. Treatment with alpha-pinene largely prevented these changes.
Conclusion: It can be concluded that alpha-pinene decreased the beta-amyloid-induced depressive behavior in rats and inhibited the neuronal loss, suggesting that this neuroprotective compound may have a critical role in depression. Alpha-pinene is probably a suitable therapeutic strategy for repressing Aβ-induced neurodegeneration

Abstract
Background & objectives: Research on intelligent nanomaterials that accelerate the process of nerve regeneration and treatment by different methods such as antioxidant effects, stimulation of nerve cell proliferation, modulation of the immune system and inflammatory factors is great importance. The aim of this study was to prepare cinnamon-coated cerium oxide nanoparticles and evaluate its antioxidant and cytotoxicity effects on PC12 cell line.
Methods: Cinnamon-coated cerium oxide nanoparticles were prepared and their structural properties were evaluated by transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR). To evaluate the antioxidant properties of the compounds, free radical trapping methods 2 and 2 diphenyl-1-picryl hydrazyl were used. Cell viability in the presence of compounds was measured by a toxicity test (MTT) [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide]. Data were analyzed by one-way analysis of variance and Tukey's post hoc test.
Results: FTIR spectra and TEM images showed the processing of nanoparticles with an average size of less than 100 nm with cinnamon coating on their surface. Also, the antioxidant capacity of cinnamon-coated cerium oxide nanoparticles was significantly higher (*p<0.038) than extracts and nanoparticles alone at similar concentrations. Evaluation the results of cytotoxicity showed that the lowest toxicity was observed in the cinnamon-coated cerium oxide nanoparticles group.
Conclusion: Results showed higher antioxidant properties and low cytotoxic effects of cinnamon-coated cerium oxide nanoparticles compared to other groups, which leads to better efficacy, proliferation, longer cell survival, its green synthesis and coverage by cinnamon
