Abstract
Tympanic membrane perforation is a world wide common problem particularly in under developed & developing countries. In the current study 352 patients were studied in a period of 6 months period. The age of the patients were between 2.5 to 86 years old. It wasn’t possible to find any significant difference between men and women. The most common form of perforation was central, and the least form was total. The most common cause of perforation was infection with traumatic manipulations and compression injuries coming after. The average amount of hearing loss was found to be 31.9 db which shows presence of some degrees of ossicular and middle ear malfunction.

Abstract
Introduction: Tension headache is the most common type of headache. Tension headache is mostly caused by stress, anxiety and depression. Treatment is by pharmacological and nonpharmacological methods. Nowdays nonpharmacological methods are used increasingly. This is a response to the over use of drugs, side effects and cost. The purpose of chronic tension headache.
Materials and Methods: This research is a clinical trial study. 25 women suffered from chronic tension headache were treated by massage during 5 weeks. Samples were asked to record headache indexes in a checklist four times a day (before breakfast, before launch , before dinner and before sleep) through these 5 weeks. Data from the first and fifth weeks were recorded as pre and post intervention data and data from the second, third and fourth weeks of investigations were recorded as the data during intervention. During the intervention samples were treated twice a week for 20 minutes each time with the friction massage on posterior parts of the neck and shoulders. Headache indexes included: intensity, frequency and duration of headache, headache intensity was recorded using 11 points criteria. Headache frequency was measured by calculating the days of headache in a week and the duration of the headache was calculated by dividing sum of headache hours in a week to the frequency of attacks. Data was analyzed by analysis of variance and Tukey test.
Results: Results showed the positive effect of massage in which headache indexes showed a meaningful difference in three stages of pre, during and post intervention (p<0.01).
The recovery rates for each index were 52%, 28% and 57% respectively.
Conclusion: Massage therapy resulted in the reduction of intensity, frequency and duration of tension headache and can be useful in treatment of tension headache .

Abstract
Introduction: Sodium arsenite is an environmental pollutant which its amounts in industrial cities are more than other places because of its use in chemical industry. Human populations are exposed to this chemical compound through food, soil, air and water which has toxic and histopathological effects on different body organs including kidney. The aim of this investigation is to study the quantitative histopathological effects of sodium arsenite on the kidney structure of rats. Materials and Methods: 12 male Wistar rats with mean body weight of 200±20 g were randomly divided into 2 groups (n=6). One treated with sodium arsenite (8 mg/kg/day in drinking water) and the other one (the control group) received drinking water only. 2 months after treatment the rats were weighed, anesthetized with ether and dissected. The left kidney was taken out, cleaned, weighed and then fixed in 10% formaldehyde solution. After obtaining 1mm thick slices, tissue processing was carried out, then 5µm thick sections were prepared and stained using H&E method. Slides were finally studied stereologically and data was statistically analyzed using paired sampled t-test and the means were considered significantly different at p<0.05. Results: The results of this investigation indicated significant reduction in the total mean volume of kidney (p<0.001), cortex (p<0.001), and medulla (p<0.003) in sodium arsenite treated group compared to the control rats. The mean volume of tubules and interstitial tissue as components of cortex reduced significantly compared to the control group (p<0.003).The mean volume of glomeruli and Bowman's capsule was significantly reduced in treated group (p<0.001), while the other components did not show a significant reduction in volume. A significant reduction was also found in the kidney (p<0.002) and the body weight (p<0. 01) in the treated group compared to the control ones at the end of the experiment. Conclusion: It was concluded that exposure to sodium arsenite leads to histopathological changes in kidney structure, however more studies are needed to determine the effects of these structural changes on the kidney function.

Abstract
Introduction: Opioids abuse is a nationwide problem in our country. Regarding the potential of these drugs in crossing placenta they can cause many defects in fetuses of human and also animals. In the present study, the effects of maternal Morphine consumption on olfactory bulb development in rats have been investigated. Materials and Methods: Female Wistar rats (weight: 250-300g) were crossed with male rats and the zero time of pregnancy was detected. Existence of vaginal plug and also sperm in vaginal smear were indicators of mating and pregnancy. Experimental group received 0.05 mg/ml of Morphine in drinking water daily. On embryonic day 19, pregnant animals were anesthetized by Chloroform and embryos were taken out surgically. Weight of the embryos was determined by a digital balance and their length (Crown-Rump, Frontal-Occipital, Biparietal, Abdominal-Transfer and Anterior-Posterior diameters) were determined by a caliper. Then embryos were fixed in Formalin 10% and tissues were processed and sectioned and stained in Hematoxilin & Eosin and Bielschwosky staining methods. These sections were investigated for olfactory bulb development by MOTIC software and light Microscope. Data was analyzed using t-test. Results: The decrease in embryonic weight and their diameter for experiment group was significant. In microscopic study, the increase in thickness of mitral layer and the decrease in total number of Tufted, Mitral and Granular cells in experimental group were significant. Conclusion: This study showed that oral Morphine consumption leads to olfactory bulb defects.

Abstract
Background: Molybdenum is an essential trace element for both animals and plants. Molybdenum (Mo), which functions as a cofactor for a limited number of enzymes including xanthine dehyrogenase, aldehyde oxidase, and sulfite oxidase in mammals, is believed to be an essential trace element in animal nutrition. The aim of this study is to evaluate the hepatoprotective potential of sodium molybdate against carbon tetrachloride (CCl4) induced liver damage. Materials and Methods: In an experimental study, adult male rats received daily oral administrations of different doses of sodium molybdate (0.05, 0.1, and 0.2 g/kg bw) along with intrapertioneal CCl4 (50% CCl4 in olive oil, 1 ml/kg bw) twice a week for 28 consecutive days. Results: Histopathological examinations in CCl4-treated rats showed extensive liver injuries characterized by extensive hepatocellular degeneration and necrosis, fat degeneration, and inflammatory cell infiltration while histopathological changes induced by CCl4 were significantly attenuated by sodium molybdate treatment. Conclusion: The results of this study suggest that sodium molybdate could protect liver against the CCl4-induced oxidative damage in rats, and this hepatoprotective effect might be contributed to the protection of liver by preventing the toxic chemical reactions which generate oxidative stress, lipid peroxidation, and molecular changes which ultimately lead to liver tissue necrosis.

Abstract
Background: Sodium arsenite has adverse effects on the reproductive system and vitamin E is a strong antioxidant and reproductive factor in the reproductive system. The aim of this study was to investigate the effect of vitamin E on the structure and the number of ovarian follicles during its development in rats treated with sodium arsenite. Materials and Methods: Pregnant Wister rats (n=4) were divided into 4 equal groups, including control, vitamin E (100mg/kg/day), sodium arsenite (8mg/kg/day), and sodium arsenite+vitamin E. Oral treatment of the pregnant rats started from the 7th day of pregnancy till the end of the weaning and continued till the age of 120 days. After the treatment period, the right ovary was removed and fixed, and then the mean number of ovarian follicles and atretic follicles, mean thickness of zona pellucida, and volume of oocytes and its nuclei in different types of follicle were determined. Data were analysed using one-way ANOVA and the mean difference was considered significant at P<0.05. Results: In the vitamin E+sodium arsenite group, significant increase(P<0.05) in the total number of follicles, mean number of primordial, primary, secondary, antral, and graafian follicles, significant reduction (P<0.05) in atretic follicles, and significant increase(P<0.05) in the thickness of zona pllucida in secondary and antral follicles as well as oocyte volume in parimordial and primary follicles and its nuclei in primary, secondary, antral, and graffian follicles were observed in comparison with the other groups. Vitamin E in the sodium arsenite+vitamin E group increased the number of different types of follicles and the thickness of the zona pllucida (P<0.05), decreased the number of atretic follicles, and increased the volume of oocyte and its nuclei to the level of the control group. Conclusion: Vitamin E can be administered as a supplement to compensate for the adverse effects of sodium arsenite.

Abstract
Background: Alpha-tocopherol, as a strong antioxidant, plays an important role in testraining free radicals. The aim of this study was to investigate the effect of Alpha-tocopherol on cell proliferation and restraining apoptosis in rat bone marrow mesenchymal stem cells.
Materials and Methods: In this research study, the rat bone marrow mesenchymal stem cells were extracted under sterile conditions using flashing-out method. At the end of the third passage, cells were divided into groups of control and Alpha-tocopherol with doses of 15 and 25 µM and were treated in the osteogenic media cell medium containing 10% fetal bovine serum, 10 mM β-glycerol phosphate, 10 nM dexamethasone and 50 µg/ml ascorbic 3-phosphate] for a period of 21 days. Then, cell proliferation, DNA damage, expression of Bcl-2 and Bax genes and the morphologic changes of the cells were investigated during the procedure of osteogenesis. Data were analyzed using one-way ANOVA and means difference was considered significant at p<0.05.
Results: Cell proliferation, the size of nuclei diameter and expression of anti-apoptotic Bcl-2 gene showed a significant increase in mesenchymel stem cells treated with Alpha-tocopherol (p<0.05) in a dose dependent manner compared to the control cells. Also, cytoplasm extension was seen in the cells treated with Alpha-tocopherol, compared to the control group. Since Alpha-tocopherol causes a significant decrease in DNA damage and the expression of apoptotic Bax gene, compared to the control group, therefore it can suppress apoptosis in bone marrow mesenchymal stem cells, in a dose dependent manner .

Abstract
Background: The aim of this study was to investigate the acute effect of supplementation Jadvar on aspartate aminotransferase (AST) and alanine aminotransferase (ALT) enzymes after exhaustive incremental exercise in men's handball.
Materials and Methods: In this semi-experimental double blinded study 12 handball players with at least 2 years record in league (with average age=21.42, height=186cm, weight=83.25, and body mass index=24.09kg/m2) divided into 2 groups (n=6) accidentally. Both groups performed maximum Bruce protocol until exhausting level. Before (fasting) and after performing protocol ,blood samples were taken from middle forearm vein and transferred to lab then supplementation group consumed three 500 mg jadvar capsules and control group consumed three 500 mg maltodextrin for 7 days daily. 24 hours after eating last capsule ,they performed maximum Bruce protocol up to exhausting level and the samples were collected like primary protocol blood samples before (fasting)and after performing protocol and were transferred to the laboratory.
Results: The results of dependent and independent t-test showed that consuming jadvar supplements for 7days did not have significant effect on aspartate aminotransferase(AST) and alanine aminotransferase(ALT)(p≥0.05).But alanine aminotransferase in supplementation group (16.83 mg.dl-1) decreased in comparison to placebo group (20.5 mg.dl-1). Also, aspartate aminotransferase was increased from 28 mg.dl-1 to 35.17 mg.dl-1 , but neither decrease nor increase was not meaningful (p≥0.05).
Conclusion: It seems that acute consuming of jadvar supplement and one session incremental exercise does not have meaningful effect on AST and ALT in man handball players.

Abstract
Background: The rhizome of Iris songarica Scherenk has been prescribed as anodyne in Persian traditional medicine system. However, its effects have never been investigated experimentally. Thus, the present study was designed to evaluate the antinociceptive and anti-inflammatory effects of alcoholic extract of Iris songarica Scherenk rhizome in mice.
Material and Methods: In this experimental study, adult male balb/c mice were used. 40 animals were allocated into five equal groups (control, morphine 5mg/kg, the extracts at doses of 100, 200 and 300 mg.kg) and tested for antinociceptive evaluation via using hot-plate in 30,60 and 120 minutes after the investigations. Also, the other 36 mice were divided into six equal groups (no-inflammation control, inflammation model, dexamethasone 4 mg/kg and the extracts at doses of 100, 200 and 300 mg.kg) and evaluated for anti-inflammatory activity in xylene induced inflammation model. All the investigations were done via intraperitoneal injection. Data were analyzed using one-way ANOVA or Kruskal-Wallis tests in SPSS.
Results: Compared to the control group, the extract at the all doses could increase latency time in hot plate test at 30, 60 and 120 minutes after investigation (p<0.05).This potential was comparable to morphine in the high doses or long time. In addition, the extracts at the all doses exhibited high anti-inflammatory activity which was comparable to dexamethasone (p<0.001).
Conclusion: The results of present study clearly showed that Iris songarica Scherenk rhizome has antinociceptive and anti-inflammatory activities in mice.

Abstract
Background and Aim: Recently, there is increasing concern about the declining of male reproductive health. Oxidative stress has been proposed as a possible mechanism contributed in reproductive system failure. Dorema aucheri that is being used in Persian folk medicine has been supposed to have male fertility-enhancing properties. Present study was done to evaluate the impacts of Dorema aucheri on oxidative status and reproductive parameters in male rats.
Materials and Methods: In this experimental study, healthy adult male Wistar rats were treated with 100, 200 and 400 mg/kg of ethanolic D. aucheri leaves extract via gavage for 70 days. Blood samples were collected for analysis of testosterone, LH and FSH serum levels. Reproductive organs weight, density, motility and morphology of spermatozoa, seminiferous tubules diameter, germinal epithelium height and also testicular levels of malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GPx) were evaluated.
Findings: Significant (p<0.05) increases were seen in the testis and epididymis weights of male rats treated with 200 and 400 mg/kg D. aucheri extract. In rats treated with D. aucheri extract sperm density and percent of morphologically normal sperm were significantly (p<0.05) higher. No significant differences were seen in serum testosterone, FSH and LH levels between D. aucheri extract-treated groups and controls. D. aucheri significantly (p<0.05) reduced malondialdehyde (MDA) levels and also increased superoxide dismutase (SOD) and glutathione peroxidase (GPx) activity in testicular tissue of rats.
Conclusion: Present study indicates that D. aucheri leaves extract has beneficial effects on reproductive parameters in male rats which might be a consequence of its antioxidant properties. |

Abstract
Background and Aim: Radiation therapy is the destruction of cancer cells that in all patients with breast cancer reduces tumor recurrence, relieves pain in local tumors and metastases. There are different treatment methods around the world such as electron, photon alone or a combination of both types of fields.
Materials and Methods: In this study, photon therapy (PT) and mixed photon-electron therapy (MPET) were used to treat malignancies of the supraclavicular lymph nodes. 30 patients with right-sided breast cancer with local lymph node metastasis were recruited. The ISOgray software was utilized to collect data about treatment planning methods with PT and MPET.
Findings: The maximum and mean delivered doses of radiation to the supraclavicular region were 52.08±1.64, 42.59±0.51 Gy and 54.24±1.64, 43.67±0.43 Gy in the PT and MPET methods, respectively. The mean irradiated volumes of supraclavicular fossa that received 90% of the radiation dose were 59.74±1.94% and 70.26±0.94% in the PT and MPET methods, respectively (p=0.004). The maximum doses delivered to the spine were 14.66±1.9 Gy and 10.22±0.92 Gy and the thyroid were 42.62±3.1 Gy and 37.67±5.02 Gy in the PT and MPET methods, respectively.
Conclusion: The maximum doses delivered to the spine and thyroid significantly diminished by the novel method. Additionally, supraclavicular region received higher maximum and mean doses in the new treatment modality compared to the conventional methods. The new method improved dose coverage for the tumor.
