There is general consensus about the exercise therapy، as a prevention and treatment of low back pain. But because of different methods of treatment، there is no sufficient evidence about the superiority of one method to another. In this study، the effect of 6 weeks of core stability exercise on pain، and trunk endurance muscles were investigated in girl’s students with chronic low back pain. A total of 18 patients with a mean age، (24/11±0/31 years)، height، (155/42 ±0/003 cm) and weight، (67/59±4/50 kg)، were selected among all recalling student that volunteered for this study in Birjand University، and then randomly divided in two groups، as training (10 subjects)، and control (8 subjects) groups. The pain levels and trunk muscles endurance were measured by Quebec back pain questionnaire، Sit- up and Sorensen، test respectively. The core stabilization exercises were exerted on a regular basis within six weeks of each 3 sessions a week، each session was conducted for about 45 minutes. For statistical analysis، the Kolmogorov - smirnov normality test، Pearson correlation and T test were used. the results showed، a significant reduction in pain levels، significant increase in trunk muscle endurance (P˂0/05)، however، no significant difference was found between two groups. it can be stated that the core stabilization exercises، can be used for reduction of the pain، and it can be considered as a suitable exercise for treatment of low back pain.

Diabetes mellitus is a chronic disease recognized by a reduction in insulin secretion due to the malfunction of β cells in the pancreas or an increase in the cell’s resistance to insulin. Todays، the trend in the treatment of diabetes by herbal medicines which have fewer side effects than chemical drugs has promoted. The aim of the present study was to evaluate the effect of hydro - alcoholic Prosopis farcta leaf extract on the blood glucose in diabetic rats. In this study، 45 male rats were randomly divided into three groups: 15 healthy controls and diabetic controls and diabetic treated by Prosopis farcta leaves extract. Type 1 diabetes was induced in rats with 300-150 g weight by injected Streptozotocin at 60 mg / kg dose. Diabetic rats were treated daily with 300 mg / kg hydroalcoholic leaf extract of P. farcta for 30 days. Healthy control and diabetic control groups received distilled water during this time. Then the blood glucose was measured at day before and days 15 and 30 after injection of extract. Based on the results، the weight of rats did not change in healthy controls and diabetic controls and treated diabetic. Blood glucose level in the treated diabetic group decreased compared to the control group at day 15. The results of this study showed that hydroalcoholic leaf extract of P. farcta had antidiabetic effects.

particulate air pollution is one of the main sources of air pollution in urban areas that is generated usually from various sources such as vehicle exhaust، industrial combustion processes or secondary conversion of gaseous pollutants. Particulate matterlessthan2. 5micronsin diameter، penetrate deep into the lungs and are caused respiratory problems. 24-hour standard of PM2. 5 is 35micrograms per cubic meters. The aim of this study was analysis of PM2. 5concentration in Mashhad city، Iran in 2013. this study was cross-sectional and within a year (from April to March2013) was conducted. Results were analyzed using one-way ANOVA.، and then compared with the Environment Protection Organization’s standard rates. the results revealed that the maximum concentration of PM2. 52. was، 42. 34μ/m3 at Daneshgah station. The results revealed that24-hour maximum concentration of PM2. 5 was46. 88 in the autumn. The results showed that September and winter seasons had the highest prevalence rate that in some cases، PM2. 5concentration is more than the standard rate. The Daneshgah station has the highest density of PM2. 5 to be allocated.

Premature baby mothers are more anxious than other parents. High levels of anxiety change the interactions between mother and baby and have negative consequences which cause anxiety disorders and cause their parents to fail to play their roles well. This anxiety can be effective on the growth of baby. Therefore، this study was conducted to control their anxiety and to provide training for them. This study was a clinical trial study (code: 18035N1) on 50 primiparous mothers with premature infants at Nohom DeyHospital of Torbat Heydariyeh. The simple random method assigned to experimental and control groups. The tool was Spielberger anxiety questioner. One day after being admitted to the newborn، neonatal care، was given to intervention group in 45 to 60 minutes. Mothers’ level of anxiety was collected two times، 24 hours after admission (pretest) and at discharge from the neonatal unit (post-test) and the results were analyzed through chi-square and t-test. In demographic variables there was no significant difference between the two groups (p < 0/005). Before the intervention، the mean anxiety scores in intervention group and control group were 63/67 ±8/32 and 58/17±10/03، respectively. There was no significant difference (p = 0/431) while the mean anxiety scores after the intervention in intervention group and control group were 29/41±9/06 and 67/15±12/3 (p = 0/002)، respectively. The present study showed that infant care training reduces anxiety in mothers of preterm infants، so this strategy can be applied by the authorities to reduce the consequences of the problem caused by this anxiety for mother and baby

Heavy metals pollution is a worldwide problem due to the chemical stability and accumulation properties in living things. High levels of these metals increased mortality، morphological abnormalities، growth retardation and genetic effects in humans. This study investigated the concentration of heavy metals in SIRJAN plain groundwater resources and compared the results with current standards. This cross-sectional study was performed in Environmental Health Engineering Research Center of Kerman University of Medical Science from April to June 2014. Samples were collected from 40 deep wells، in the middle of each month. EC، TDS، pH and temperature were measured at the sampling site. Heavy metals were measured using ICP. Sampling، sample storage and laboratory tests were done according to Standard Methods for Water and Wastewater Examinations. According to results، the mean concentration of Zinc، Chromium and Cadmium in samples were not exceeded 0. 8، 1 and 0. 5μg/l، respectively. The average concentrations of Pb and Cu were 2. 842 and 26. 743 μg/l، respectively. Average amount of electrical conductivity (EC) was 6820. 575μs/cm. Mean concentration of total dissolved solids (TDS) was 3891. 57mg/l. pH mean was 7. 5 and mean of temperature was 21. 95OC. The results show that studied resources are reliable for drinking and agricultural purposes in terms of Cadmium، Chromium، Copper، Zinc، Lead and pH. In addition، these resources are not exposed to pollution due to the various reasons such as geological compositions، limited industries in the region، reduction or absence of municipal and industrial sewage infiltration into water supplies and the geographical conditions. But the recent drought، reduced rainfall and indiscriminate withdrawal of ground water resources، has led to TDS and EC exceed national، USEPA and FAO standards and WHO guidelines for drinking and agricultural purposes.

Life style is one of the most important domains of self- care. Life style is a personal unique pattern including characteristics، behaviors and habits that everyone performs and improper life style led to diseases and accidents. According to importance of the subject، the current study was done with the aim of Identification Self- care pattern related to Life style and its related factors among female high school students in Gorgan. In this cross sectional-analytical study that was done in 2013،300 female high school students in Gorgan were selected through multi-stage sampling method (random and cluster) and Data were collected using the valid and reliable questionnaire that included demographic and life style via self report. Then data were analyzed using SPSS18 and one way ANOVA test. Educational level in their fathers and mother was Diploma and under diploma in 71. 6 and 78. 7 respectively. Their father job was non- government in 42. 3% and their mother job was housewife in 72%. Life style was in the low level in 1. 7% of the under studied population، 46. 7% in moderate level،45. 3% in good level and 3. 3% was in excellent level. There was significant relation between life style with parents income، parents education، parents job but there wasn’t significant relation between life style with Body Mass Index. Self- care pattern related to Life style in the half of the students isn’t in desirable level. So we recommended appropriate intervention، especially educational intervention for promotion of healthy life style

Many Studies about Epidemiology and medical sciences that measured desired outcome at frequently individuals over times are done based on a longitudinal design. the features of a data set is repeated observes. For this reason، requirement of independence observation in longitudinal data is violated that causes this kind of data needs the specific statistical method. One of the methods that is used for analyzing this kind of data is marginal model. generalized estimating equations (GEE) is a famous statistical inference for this. By this، the purpose of study GEE applications in data comes from the result of the clinical trail is to survey the treatment of infancy colic.

In this study، in addition to introduce generalized estimating equations benefits the usage of it on analyzing probiotics impact on infancy colic in breast milk fed by using SAS 9. 2 soft ware. These data include 98 infants that recourse pediatric gastroenterology clinic in Booali hospital in Sari. it is the result of accidental one side trial study. Patients were randomly divided in two 49 members groups. the control group was given placebo and another group was administered Biogaia oral drop in 28 days. In this study، the response variable is the average crying time of infants during the week –fist day،7th day، 14th day and 21th day were recorded respectively.

The result showed that using probiotic drop، time and Maternal smoking had significant impact on infancy colic. the crying time of those babies that used probiotic drop reduced 9 hours in compare with those who didn’t use. (p<0. 05) the children crying with the passage of per week 3. 5 hours decreased (p<0. 05). Conclution: By considering the correlations among observations and violate the independent observation default the GEE as a specific methods that considered the correlation among observations is an appropriate statistical method. The results of GEE statistic methods in longitudinal data showed that treatment with probiotics improves infant colic in children.

The environmental pollution induces rapid development of new technologies cases problems such as pollution of soil، water and air. Heavy metals contaminated can disturb Biodiversity soil. Phytoremediation is one of them new techniques in cleared of heavy metals in soil. A Phytoremediation method enables leaving a contaminated soil from the elements with accumulation of heavy metals in the shoots of plants. The purpose of this study was to evaluate the removing heavy metals in contaminated soil by phytoremediation. This study performs on studies by reviewed _ descriptive، the effects of flooding and erosion، on environmental pollution and disasters; were collected based on available reviewed articles. Criteria for entry data was related to articles the topic and containing research keyword. The results showed significant differences are between cadmium concentrations in plant shoots and roots of Helianthus plants. Also significant differences observed between Transfer factors and bioaccumulation in another species، therefore extracted potential sunflower plant higher than sorghum. The results showed that the distribution of lead in different organs of sunflower plant can had complied concentrations absorb in lead levels of these elements in soil and with increasing concentrations of soluble lead in soil، were also increased lead concentration in plants. lead and cadmium were absorbed in sunflower shoot plant higher than root.
