Introduction: The phone's sound beams are known to be a valid test that reflects the activity of foreign hair cells, and are therefore very useful for assessing cochlear changes, such as those that occur after exposure to noise.
method: In one clinical trial, 74 volunteers aged 18-25 were examined by simple random sampling. The results of audiometric tests of the participants' pure sounds and tympanometry were within the norm on the day of the experiment. In this study, the phonetic tests of the phone were spontaneous, transient, and distorted from both ears of the subject, which was considered as a basic level of evaluation for us. Then a person's ear was selected and in the intensity of SPL 100 decibels and for 5 minutes in his ear was given a turn. After 2 minutes after the end of the presentation, the previous evaluations were repeated in both ears and the range of responses in both ears was compared.
Results: In 34 participants, submucosal nostrils led to a decrease in amplitude or SOAE responses. One of the interesting findings in this study was the emergence of new peaks in SOAE responses in the opposite ear after the presentation of the sound. The proposed noise created a significant statistical decrease in the range of TEOAE response both in the affected ear and in the opposite ear. Comparing the mean amplitude of DPOAE responses before and after exposure to shift-induced noise in the ear was significant in the Hertz range of 1699-6299, but this comparison was not significant in the opposite ear. The mean time of DPOAE incubation before and after exposure to shingles did not show a statistically significant difference in both the affected ear and the opposite ear.
Conclusion: The findings show that the phone's sound beams are a good tool for tracking hearing damage caused by noise. TEOAEs are also more sensitive to tracking than other tests, and can even be used as a very fast screening tool to assess susceptibility to hearing damage caused by noise before entering high-end industrial environments. And considered sound.

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 .

Introduction: Disturbance  between  production  of  free radicals  and  antioxidant  defense is  named  oxidative  stress. One  of  the  main  sources  of  free  radicals  is  smoking  that  induce  oxidative  stress.
Materials  and  Methods: This  is  a  cross  sectional  study  in  which  questionnaires  including  information  such  as  age, sex, education, history  and  number of  smoking  and  history  of  special  disease  were  filled. Case  group  were  smokers (n=43)  who  were  smoking  at  least  5  years  and  their  mean  age  was  37.7  year. The control  group  was  consisted  of  43  nonsmokers  which  were  matched  for  age  and  sex.  They  were  evaluated  for  oxidative  stress  markers  including  thiobarbituric  acid  reactive  substance  (TBARS)  indicator  of  lipid peroxidation (LPO), ferric  reducing  ability  of  plasma (FRAP) indicator  of  total  antioxidant  capacity, total  thiol (SH)  groups  and  gammaglutamyl  transferase (GGT) levels  in  blood.
Results: Results  showed  that  induction  of  oxidative  stress  in  smokers  as  revealed  by  decreased  FRAP (1.89±0.03 vs  2.24±0.04, p=0.01) and  plasma  Sh  groups  (0.22±0.08 vs  0.81±0.48, p=0.01)  in  comparison  to  those  of  controls. The  activity  of  GGT  and  level  of  LPO  increased  but  were  not  significant . Also  the  correlation  between  history  of  smoking  and  oxidative  stress  was  not  significant.
Conclusion: It  is  concluded  that  smoking  have  decreased  FRAP  and  SH  groups which  may  put  smokers  at  future  consequences  of  oxidative  stress.  It  seems  that  improving  antioxidant  system  in  smokers  is  effective.

Introduction: Investigations has showed that prenatal exposure to Morphine causes drug dependency and behavioral complications in new born rats. In this study effect of prenatal Morphine on the development of basal ganglia in rat embryos is investigated. Materials and Methods: In this experimental study 36 female rats with body weight between 250-300 grams were selected. After crossing with male rats they were divided into six groups of 12days control-Morphine, 14days control-Morphine and 17days control-Morphine groups. Morphine groups received 0.01mg/ml Morphine through their drinking water until the 12, 14 and 17th day of pregnancy (20ml each rat). Then rats were anesthetized and embryos were taken out and fixed. Their body weight and crown-rump length were measured. Then 5 micrometers sections were provided and stained using H & E method which were then evaluated using mutic program. Results: Body weight and length of embryos were reduced significantly in the 12&14th day of Morphine group rats in compare to their controls. The significant reduction of Basal Ganglia thickness was also found in all Morphine groups compared to their controls. Conclusion: Results showed that prenatal Morphine exposure may cause impairment in change development of Basal Ganglia.

Introduction: Hypomagnesemia hypercalciuria nephrocalcinosis (HHNC) is a rare syndrome due to mutation defect in CLDN-16 gene. Its product is paracellin, a protein in henle loop paracellur area which acts in magnesium and calaium reabsorption. In this article a case of HHNC is reported. Case: The patient is a 3 years old boy presented with tetany, polyuria and polydipsia. Imaging study revealed medullary nephrocalcinosis. Laboratory investigations showed hypomagnesemia, hypercalciuria, hypermagnesiuria and normal arterial blood gases. In 2 years follow up, no neurological diseases, growth failure, or rickets were seen. He was treated with Hydrochlorothiazide and Potassium polycitra for prevention of nephrocalcinosis and progressive renal failure. Conclusion: HHNC is a rare syndrome presenting with hypercalciuria, hypo- magnesemia nephrocalcalcinosis, tetany, polyuria and polydypsia which progresses to end stage renal failure in 2nd or 3rd decades. Early diagnosis and some treatment modalities like Hydrochlorothiazide or polycitra-k can delay this process.

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 Background: Approximately 15-20% of pregnancies terminate to abortion. More than 50% of spontaneous abortions in 8-15 weeks pregnant mothers are related to genetically abnormalities. So, approximately 95% of them are related to numerical and 5% structural chromosome aberrations. Until now, neither of known human chromosomal abnormalities are treatable, and only way against these diseases limit to prenatal diagnosis and abortion of affected fetuses. The purpose of this study was determined the chromosome aberrations with cytogenetically methods. Materials and Methods: In this cross-sectional analytic study, 56 aborted fetuses were studied to detection of abnormalities frequency. Amnion-chorine culture, placenta, fetal tissue and aborted products from metaphase cells for gathering metaphase cells were used. Results: After cell culture, chromosome typing and GTG-banding Technique, trisomy 21 with highest frequency (12.5%) and isochromosomy 21, X and monosomy X with lowest frequency (1.8% for each them) was resulted. Conclusion: Not only chromosomal aberrations have important role in recurrent miscarriages, but also frequency rates of chromosomal aberrations in our country are similarity with other countries. Also cytogenetically diagnostic methods such as GTG-banding are a powerful and reliable technique for investigation of parents with recurrent abortion.

Background: The theory of mind acts as an umbrella which covers the perception of children of others’ mental conditions under its banner and paves the way for child’s social cognition. This study was designed to compare the effects of different variables such as intelligence quotient (IQ), sex, age, and mental maintenance on the theory of mind development levels in autistic and normal children. Materials and Methods: In this case-control study, 19 autistic and 19 normal children were selected based on the in-reach sampling procedure and were also matched by age. The participants completed Wechksler intelligence scale for children, Stimman theory of mind task, and mental maintenance task. Results: In comparison to normal children, autistic children showed a clear deficiency in their theory of mind development levels however, age did not have a significant effect in this regard. Conversely, IQ and sex had significant impacts on the development of theory of mind. In addition, mental maintenance, alone, had a significant effect on the theory of mind. Conclusion: Noticing the existence of some primary levels of theory of mind in autistic children, some aspects of theory of mind can be compensated for through the provision of basic instructions and guidelines for development of intellectual and cognitive abilities in early childhood and primary stages of diagnosis.

Background: Lead (Pb) brings about a variety of cognitive, mental, renal, and blood system disorders by inducing oxidative stress. The aim of this study is to compare blood and urine parameters in the workers exposed to Pb and zinc (Zn) with those in the control group. Materials and Methods: An analytical cross-sectional study was conducted with a total number of 134 subjects. The case group included 67 male workers with the age range of 22-65 who had at least worked a minimum of one work shift for two years in the Zn-Pb mine located in the southwest of Arak, Iran. Control subjects consisted of 67 farmers of a village near the mine who had no history of occupational exposure to Pb, Zn, and other metals. Mental disorders were evaluated through the standard Scl-90-R while cognitive disorders were evaluated via the Mini Mental Status Examination (MMSE). Results: The mean level of blood and urine parameters did not reveal significant differences between the two groups. The mean scores of physical complaints, anxiety, and aggression scales were significantly higher in the case group than the control (p<0.05), whereas the mean scores on MMSE did not reveal a significant difference between the two groups. Conclusion: The oxidative stress of Pb led to mental disorders as a result, the mine workers suffered from more psycho- pathology and are in need of greater care. Due to the impacts of Pb and Zn, the proper use of safety equipments and taking daily showers can reduce the risk of absorption of toxic agents and their subsequent hazards for workers.

Sleep is one of the basic needs of human and any disorder in its natural flow in addition to creating psychological problems can reduce the individual performance. There are descriptions and references about sleep and its features in Quran. In Naba Surش sleep has been referred to as a weakness that indicates a disease state. However, the conditions for the occurrence of sleep can be inferred from Kahf Sura, verse 11, which states: “a major quality of sleep is that one cannot estimate its duration”. In several other verses, sleep is said to be similar to temporary death. Substances such as endorphins, cortisol, and encephalin cause euphoria and have direct impacts on different parts of the body including skeletal muscles that lead to muscle comfort during the day. The amount of secretion of these materials into the body in the morning hours significantly increases. Therefore, waking up early in the morning can bring about euphoria and can have positive impacts which last till the end of the day. According to the findings released by the International Agency for Research on Cancer World Health Organization, men and women who work night shifts are at a greater risk of developing breast cancer and prostate cancer, respectively. Night sleep is a divine blessing that God has endowed people and God in verse 23 of Rome Sura refers to sleep as “one of the signs revealed to people” and asks people to search and investigate about it so as to realize to what extent night sleep can contribute to human perfection and success

Background: Eating and drinking according to health instructions is a major factor in health. Islam recommendations regarding nutrition ensure not only physical health but also mental health. While advising Muslims to consume meat as much as their body requires, Islam forbids certain types of meat. This study is to investigate the effect of pork consumption on human health from the perspective of Quran and medicine. Materials and Methods: Relevant Quranic verses and Hadith and the existing literature were reviewed and described through the use of specific keywords. We utilized relevant materials from the Holy Quran and Hadith and also conducted a literature search through specific related keywords. Results: In four Surahs of Quran and Hadith from the infallible Imams, pork consumption is forbidden. The presence of a group of amines, carcinogenic agents, high fat, and a high level of growth hormones turns pork into a sutoxin product. In addition, the presence of significant zoonotic diseases, quick decay, and easy contamination are other reasons which make pork consumption harmful for human. Conclusion: Noticing the significant role of nutrition in physical and mental health, divine religions have pronounced recommendations on using decent and healthy nutrition and refraining from using the unhealthy materials. Pork is one of these unhealthy and unusable materials which unfortunately, due to lack of sufficient awareness, is still consumed by some.

Background: The current paper set out to investigate the level of asbestos fiber and asbestos body in sputum and assayed of haematological factors, liver enzymes and pulmonary function test in asbestos exposed group.

Materials and Methods: An analytical cross-sectional study was conducted with a total number of 100 subjects. The case group included 50 male workers with the age range of 25-60 who had at least worked for five years in the asbestos-cement factory. Control subjects consisted of 50 people who had no history of occupational exposure to asbestos. Lung function tests were measured with a portable calibrated vitalograph-PFT spirometer. liver enzymes were assayed with Pars Azmoon kits. Counts of red blood cells and white blood cells were assayed with a cell counter. We used light polarizan microscope to study the level of asbestos fiber and asbestos body in sputum.

Results: Asbestos fiber observed in sputum sample of workers and type of asbestos fiber is chrysotile. Asbestos bodies were found in only 10% of the workers. Decrease (but not significant) in lung function factors (FVC, FEV1, FVC/FEV1) had been seen in the workers in compare with control group. WBC, Eosinophil, neutrophil, lymphocyte, monocyte and liver enzymes levels were significantly higher (but in normal range) in workers as compared with the control group.

Conclusion: Presence of asbestos fiber and asbestos body in workers sputum samples showed workers exposure to asbestos and reduced level (insignificant) of lung function factors and increased level of leukocyte may be indicated pulmonary inflammation. These results also suggested that occupational exposure to asbestos dust may perturb liver mal function parameters

Background: Spinal anesthesia is an efficient method of providing intra operative analgesia and a safe alternative to general analgesia in many cesarean patients. Despite its advantages, SA is not free from adverse effects, which include unwanted cardiovascular events, in most cases: hypotension and bradycardia. Ondansetron is a 5HT3 receptor antagonist, with known efficacy on preventing nausea and vomiting. Maybe ondansetron given intravenously attenuates the fall of blood pressure and heart rate, by 5HT3 blocking in vagal nerve endings and effect on BJR.(Bezold jarish Reflex).

Materials and Methods: In this clinical trial 102 healthy pregnant women that were candidate for elective cesarean in hamedan fatemieh hospital during 3 months in 1390, studied. They were randomized into 2 groups: the ondansetron group, n= (51) received (4miligram) ondansetron intravenously before performing spinal anesthesia, and placebo group n= (51): received 2cc sterile water before spinal anesthesia. Spinal anesthesia was performed with hyperbaric bupivacaine (0.5%) 10 mg and sufentanil (5 µg) BP and HR were measured and recorded before and after anesthesia immediately. If hypotension happened, ephedrine 5- 10mg injected. Itching and nausea recorded every 10 min during operation by observation and question.

Results: There were no significant differences in SBP, DBP, MAP, HR and itching in both groups. Nausea and vomiting ,and mean consumed ephedrine was siginificantly different in both groups.(p=0.001, p=0.009).

Conclusion: Ondansetron given intravenously with antiemetic dose (4miligram), decreases mean consumed ephedrine and nausea and vomiting after spinal anesthesia, but doesn't have an influence on BP, HP and pruritus
