Road accidents are a major public health problem and one of the leading causes of death in the world. Some survivors of traffic accidents experience acute stress disorder and post-traumatic stress disorder during weeks to months following the accident. These disorders can have disastrous effects on victims and their inability to return to normal living conditions.
 

This was a cross-sectional descriptive study. The Post-Traumatic Stress Disorder checklist (PCL5) was used to assess acute stress disorder and post-traumatic stress disorder. The sample size was 384 people and the data were collected one week and two months after the trauma in the orthopedic, emergency and inpatient wards of Taleghani, Shohadaye Tajrish and Haftom Tir hospitals. This study was conducted between October and January 2016.
 

This study was conducted on 350 participants. About 49% of the participants (n = 172) met the diagnostic criteria for acute stress disorder and 40.6% (n = 142) met the diagnostic criteria for post-traumatic stress disorder. There was a relationship between demographic variables of age and death of a close family or friend and the severity of post-traumatic stress disorder.
 

According to the results, about half of the participants had acute stress disorder and met the diagnostic criteria of post-traumatic stress disorder. This result highlights the high prevalence of this disorder in traffic accident victims and the importance of its follow-up and control.

Application of plants and their compounds has long been significant in treating diseases mainly due to their natural potential and lower side effects than chemical drugs and presence of alkaloids, and polyphenols in their extract. Despite research carried out on the properties of such plants and popularity of blood diseases, few studies have been done on its effects on blood cells, thus, it was attempted for the first time to evaluate the effect of hydroalcoholic extract of the Pseudium guava leaf on blood cells in rats.

After extracting the leaves of guava plant, 40 adult male rats were divided into four groups. Which included control (cases with no treatment during the study) and experimental groups (cases receivied of hydroalcoholic extract of Psidium guava leaf, in different doses daily for 3 months). At the end of the test period, blood samples were counted.

The results of this study showed that the hydroalcoholic extract increased White Blood Cells and Red Blood Cells, but no significant change was observed. This increase in hematocrit was significant in the group receiving hydroalcoholic extract at a dose of 5000 mg/kg compared to the control group.

The results of the study had a positive effect on blood cells. Also, the lack of cytotoxicity with high doses of the extract of this plant means its safe use in traditional medicine.
