Background & Objective: Emphasiz to the research in any country leads to develop and progress of it, and it presents the self- sufficiency and real independence for that country .The first step to optimize the research in society is to obtain the correct understandding from
capabilities, possibilities and to find the weakness and strength aspects of investigations. This study aspeet's of has been done regarding the above-mentioned aims.
Methods: This was a descriptive-cross-sectional study, that has been done to determine the view of Ardabil province Universities scientific members' about research and its limitations by simple sampling. Data collection tools were questionnaire including two parts: the first part, consisted of personal-social specifications and the second part, consisted of five parts (personal, intra- organizational, extra-organizational limitations, characteristics and their attitudes to research.
Results: the results showed that in related to the personal limitation overworking with mean 2/75±2/48, in the intra-organizational limitations, to be low the investigation payment in relation to the passed time with mean 3102±1/14 ,in the extra-organizational ones, ineffectiveness of the investigation results in managers decision 2/81±/44, in the characteristics, sensitivity of the scientific research 2/8±1/17 and in to promote and progress of the society , with mean 4/72 ± /53 had the highest scores.
Conclusion: many factors such as parsonaling, intra-and extra-organizational and characteristic factors, attitude to research on the view of scientific members of the restriction factors

Background & objectives: Brain trauma is one of the most common causes of damage to the central nervous system which can lead to death and long-term disability. The present study aimed at investigating the effect of 8 weeks of swimming exercise on the level of memory and interleukin 10 (IL-10) in the hippocampus and prefrontal cortex of mice with brain trauma.
Methods: 40 male NMRI mice were randomly divided into four groups (control, swimming, trauma, swimming + trauma). After completing the exercise protocol, induction of trauma was performed by the weight -drop method. Ten days after trauma induction, the mice were evaluated for spatial memory with Y-maze test. The IL- 10 level was measured using ELISA technique. One-way analysis of variance and Tukey post hoc test were used for statistical analysis at a significance level of p<0.05 and using SPSS software version 26.
Results: The study results indicated that eight weeks of swimming exercise significantly increase memory in mice with brain trauma (p=0.001). Furthermore, eight weeks of swimming exercise significantly increase the level of IL-10 in the hippocampus of mice with brain trauma (p=0.001). However, this increase was not significant in the prefrontal cortex (p=0.126).
Conclusion: The results of the present study showed that swimming exercise before induction of brain trauma reduces inflammation and memory disorders and facilitates recovery after injury. Previous exercise training can probably reduce inflammation by increasing the amount of anti-inflammatory cytokines, including interleukin-10, and limit secondary damage with its protective effect.
