Abstract :

The city of Ahvaz is considered the most polluted city in the world by blowing dust from neighboring countries which makes this study important. The results show that the smaller the particles, the more permeable they become and pass through the respiratory filters and causing disease. In this study, the effect of fine particulate matters in different cities of Khuzestan province of Iran was compared on the liver histology and oxidative stress enzymes of male rats. 30 adult male rats were divided into six equal groups including control, Ahvaz, Ramhormoz, Andimeshk, Abadan, and Susangard which were treated for two months. The results of serum oxidative stress enzyme activity increased only for the glutathione peroxidase in Ramhormoz and Abadan groups. The histological examination of liver revealed bleeding, mild hyperemia, and changes in hepatocyte cells. The nuclear area in central vein region, hepatocyte area in portal, and vein regions showed significant changes. Moreover, kupffer cell number of the portal region significantly increased in Ahvaz, Abadan, and Andimeshk groups. Therefore, due to different heavy metals composition, fine dusts have different effects on blood and liver parameters which depend on their amount and duration of exposure.
