[Comparison of static and dynamic resistance exercise effects on some functional cardiovascular indices, plasma lactate and peripheral blood leukocytes in healthy untrained women]

Considering the conflicting results related to the resistance exercise-induced cardiovascular and inflammatory response, the present study was conducted to compare the effects of static and dynamic resistance training on some functional cardiovascular indices, plasma lactate and peripheral blood leukocytes in healthy untrained women. In a quasi-experimental design, twenty healthy untrained volunteers [Female, aged 20-25 years and BMI 20-25 Kg/m[2]] in two random homogeneous groups were participated in an exhaustive static [40% of maximum voluntary contraction] or dynamic leg press resistance exercise [40% one repetition maximum with 45 to 55 repetitions]. Heart rate, blood pressure, rate-pressure product [RPP] along with plasma lactate and peripheral blood leukocytes counts were determined immediately before and after the resistance exercises. Data were expressed as mean [ +/- SD] and analyzed by paired and independent t-tests at alpha

[Quality of life in burn disfigurement individuals as life in suffocation - a qualitative study]

Nowadays with improving the taking care of the burnt patients, mortality rate decreased. With the increased survival of these patients, the number of the survivors with complications increased. Among these consequences, disfigurement is the most important ones. So recently, psychosocial problems of burnt patients and their rehabilitation have been deeply paid attention to. Therefore, a qualitative study was conducted so as to obtain information concerning quality of life with burn disfigurement after being discharged from the hospital, in order to devise psycho-social support programs based on this evidence. This article reports part of a greater qualitative study. Purposive sampling and theoretical sampling was used to selecting the participants. The main data collecting tool was in-depth interviews. Thirty-four individual in-depth interviews were performed with 22 participants. The interviews were analyzed by the content analysis method and constant comparative method. After analyzing, for quality of life with burn disfigurement theme's "life in suffocation" with three core category "ruin lives", "to get tired" and "slavery disfigurement" appeared. Despite the severity of suffocation for different people was different, but it was for all participants. The evidences indicate quality of life with disfigurement even in people who few years living with problem, in a way that is inappropriate and uncomfortable as life is suffocating. Hence there exists a need to devise a proper supportive plan to enhance quality of life for these people

[ comparison of the effects of anethum graveolens and wheat germ oil on the blood oxidative stress in wistar rats]

Oxidative stress is the imbalance between production of free radicals and antioxidant defense system. Antioxidants, in little amounts, are substances which delay the oxidation of oxidants. They neutralize free radicals in different ways and consequently prevent the affliction and aggravation of different diseases such as Parkinson and cancer in which oxidants have an important role. Anethum graveolens is a highly consumed plant in Iran. This study tries to make a comparison between the antioxidant effect of Anethum graveolens and wheat germ oil as the richest source of Vitamin E. This research is designed in the experimental form and 24 male wistar rats those were randomly divided into 3 groups. Anethum graveolens water extract was given to group A orally with the dose 3 gr/kg B.W. Group B received 0.5 gr/kg wheat germ oil and the third group [C] was considered as the control group. After two weeks about 5[cc] blood was taken from the rats' hearts. The serum total antioxidant capacity was measured by FRAP method with the use of TPTZ indicator and also the rate of serum thiol groups was measured by Hu method with the use of DTNB indicator. In this method descriptive statistics [mean +/- SD] and Analyze Nonparametric Test [Kruskal-Wallis] were used. The mean and the standard deviation of the serum total antioxidant capacity were as follows: in group A 0.23 +/- 0.045 micro mol/ml, in group B 0.161 +/- 0.149 micro mol/ml and in the control group 0.144 +/- 0.175 micro mol/ml. The data showed a significant difference between A, C groups [P=0.035] and the rates of the serum thiol groups were: in group A: 0.591 +/- 0.68 micro mol/ml, in group B: 1.29 +/- 0.576 micro mol/ml, and in group C: 0.264 +/- 0.179 micro mol/ml; and between groups B and C a significant difference was shown. The results showed that Anethum graveolens water extract decreased the oxidative stress more than wheat germ oil. Therefore antioxidant defense system has been strengthened by consuming Anethum graveolens water extract which can be used as a useful supplement in a diet

determination of saliva antioxidant capacity in 15-17 year old Students of Arak high schools

Free radicals are molecules or atoms that due to their single electron have high reactivity. An imbalance between production of free radicals and antioxidant defensive system of human causes oxidative stress, which can create more than one hundred kinds of disease. Since environmental pollutants are a source of free radicals and Arak is an industrial city, this study was performed to determine the antioxidant capacity of 15-17 years old students of the city. This descriptive-analytical study was performed on 720 students [395 females and 325 males] selected by multiuse sampling. The total antioxidant capacity of saliva in these students was measured by ferric reducing ability of plasma [FRAP] method, which is based on the ability of saliva to reduce ferrous [Fe[+3]] to ferric ion [Fe[+2]]. The total antioxidant capacity of saliva was 1.53 +/- 0.065 micro m/ml. This amount was 1.64 +/- 0.071 in males and 1.42 +/- 0.059 micro m/ml in females. Our results showed that antioxidant capacity of Arak students was lower than that of antioxidant capacity in other studies. This factor, as an antioxidant disturbance, may cause different diseases in the students of this city
