Abstract
Backgrond & Objectives: Oligohydramnios is a disorder which is followed by unpleasant outcomes for fetus that can lead to termination of pregnancy before term and preterm delivery. For these patients' increase in gestational period and prevention of preterm delivery is the most important act. In this study the effect of intravenous and oral hydration therapy in increasing duration of gestation in patient with oligohydramnios was evaluated. Methods: In this study, the population was devided into two case and control groups with 30 female individual who were found to have oligohydramnios in course of hospital admission according to on sonographic results. Patients were randomly put in case or control groups. Case group were given 3-4 liter normal salin for 1 week and then were given oral hydration solution until the end of pregnancy, In each group whenever it was found that pregnancy was not possible the pregnancy continuance was stopped. Data collection was through history, physical examination completing relevant questionnaire and findings of sonography and in order to see the relationship among finding s, kitest and t-test from SPSS software were used. Results: The age means of case and control groups were 25 and 24 respectively. The mean of pregnancy duration from the diagnosis time in case group was 30.2 weeks and in control group 31.8 weeks. The mean of pregnancy terminatior in case group was 34.6 weeks and in control group 34.2. In increasing duration of pregnancy in case and control group. It was concluded that intravenous and oral Hydration therapy cause incerease in duration of pregnancy in patients suffering from oligo Hydraminos. According to the results of this study and significance of the difference.

Abstract
Background & objectives: Weight loss and hypernatremic dehydration is a common problem in infants with inadequate nutrition. Determination of risk factors and clinical characteristics of these neonates may help to prevent or early detection of hypernatremia. This study designed to determine the prevalence of clinical signs and risk factors for hypernatremic dehydration.
Methods: This study is a sectional descriptive study that conducted on 418 newborns during 1385 to 1393 AHS that referred to Ghaem hospital in Mashhad. The hypernatremic group consisted of 197 neonates with serum sodium level higher than 150 mg/dl and 221 isonatremic newborns with sodium level less than 150 mmol/L were included as controls. Both groups were compared in terms of clinical symptoms of dehydration and maternal risk factors. All data were recorded and coded. Data analysis performed using paired T test and chi square tests by SPSS 16 software.
Results: In the present study, 2.8% of infants were hypernatremic. The most common symptoms were neonatal jaundice (62.2%), hyperthermia (25.8%), lethargy (23.6%), agitation (20.8 %) and mucous membranes dryness (17.2%). Problems in pregnancy (p=0.002), inappropriate feeding techniques (p=0.000), the first lactation duration (p=0.022) and frequency per day (p=0.000) had statistically significant difference between case and control groups.
Conclusion: Prevalence of hypernatremic dehydrationis considerable in our study and identifying the risk factors may help to reduce its incidence or exacerbation. Weight loss, especially in newborns having jaundice, hyperthermia and irritability, may be helpful in the early diagnosis of hypernatremic dehydration

Abstract
Background & objectives: Caffeine can affect many physiological functions of the body. The aim of this study was to investigate the response of aerobic function, blood pressure and some immune system factors of trained men to acute caffeine consumption in dehydrated condition and warm and humid environment.
Methods: Thirty male athletes with a mean age of 26.6±3.9 years in dehydrated conditions voluntarily participated in this study, which was performed in a double-blind manner. Subjects were divided into three groups: caffeine consumption group (n=10), placebo group (n=10) and control group (n=10). The Caffeine group consumed 6 mg/kg body weight of caffeine. Sixty minutes later, the subjects performed an increasingly exhausting exercise. Blood samples collecting and blood pressure measuring took place before, immediately after and 24 hours after exercise. Analysis of variance with repeated measures (group * time) and one-way analysis of variance were used for statistical calculations.
Results: The duration of the exhaustion test in the caffeine consumption group was significantly longer than the control (p≤0.01) and placebo (p≤0.05) groups. In the blood sampling immediately after exercise, the level of leukocytes, neutrophils and lymphocytes in the exercise groups were significantly higher than the control group (p≤0.001). Also, the caffeine group experienced a lower increase in leukocytes and neutrophils compared to the placebo group (p≤0.001). Blood pressure values in the exercise groups were significantly higher than the control group (p≤0.001). Also, the caffeine group experienced a greater increase in systolic blood pressure at baseline and immediately after exercise compared to the placebo group (p≤0.001).
Conclusion: In general, exhausting exercise in a warm environment and dehydrated condition increases the number of immune system cells and blood pressure. In addition to improving aerobic function, caffeine seems to prevent further increases in the number of immune system cells, while increasing blood pressure in the normal range in warm and humid environment.
