Introduction: Traffic accidents are the second cause of death and injury and the first cause of loss of life in Iran. This study was done to recognize the relation between human Attributes and traffic events of the drivers of Ilam.

Maerials & methods: Data on traffic accidents Ilam Province during study (cross-sectional) with census method, in a one-year period (2012) were analyzed. These data were collected depending upon com form 114 and traffic experts in the accident scene. Data were entered in spss software. Statistical analyses were done by T-test, Chi-square test and logistic regression.

Findings: From 3746 traffic accidents were studied, 3317 were men (88.5%) and 107 people were women (2.9%). The average age of the drivers was (33.63±10. 83). The highest age group was between group was 21 to 30 and the minimum age group was between ages 71 to 80 years old. there was a significant statistic relation between driver’s occupation, , driver’s education, and safety belt use, violation of traffic regulation, and deaths from traffic events (P=0.001). The adjusted odds ratio for traffic accidents resulting in death or injury in the non-use of seat belts 4.70 times higher than safety belt use and traffic accidents resulting in death or injury to the adjusted odds ratio of 2.9 times higher than seen driving license was the basis of a license(p<0.05).

Discusion & conclusion: training of drivers and requiring them to legality and safety belt use can play important roles in adjusting death and injuries caused traffic accidents.

Introduction: Aging is accompanied by an increase in inflammation in the tissues of the body, which also causes lung inflammation. This study aimed to compare the effect of high-intensity interval training and moderate-intensity continuous training on gene expression of NF-κB and IL-6 in lung tissue of old and young male rats.
 
Materials & Methods: In total, 42 young and old male Wistar rats were randomly divided into 6 groups, namely young control, old control, young continuous training, old continuous training, young high-intensity interval training, and old high-intensity interval training. The training protocol included high-intensity interval training and moderate-intensity continuous training during six-week (5 sessions per week). The gene expression of NF-κB and IL-6 were evaluated using a real-time polymerase chain reaction technique, and the data were analyzed through a one-way analysis of variance and the Scheffe post hoc test (P<0.05). Ethics code: IR.ut.Rec.1395005
 
Findings: There were significant differences between old control and old continuous training (P<0.001), old control and old high-intensity interval training (P<0.001), as well as old continuous training and old high-intensity interval training groups (P=0.007) regarding the gene expression of NF-κB. Moreover, significant differences were observed between old control and old continuous training (P<0.001), as well as old control and old high-intensity interval training groups (P=0.006) in terms of the gene expression of IL-6. In addition, there was a significant difference between young high-intensity interval training and old high-intensity interval training groups (P=0.035) regarding the gene expression of IL-6.
 
Discussion & Conclusions: According to the results, both high-intensity interval training and moderate-intensity continuous training can result in the prevention of the incidence of aging-related diseases and disorders as well as the reduction of inflammatory factors in lung tissue in aged rats. However, it seems that moderate-intensity continuous training is more effective than high-intensity interval training.
