Abstract

Carbon black is one of the components of particulate matter (PM), known as cytotoxic, causing inflammationin the respiratory and cardiovascular system, and able to pass through the placental barrier, which may affect the fetus. The effects caused by pollutants depend on the intensity and time length of the exposure.The objective of this study is to identify Vascular Endothelial Growth Factor (VEGF) and Mitogen Activating Protein Kinase (MAPK) as an indicator of maternal placental inflammation in pregnant rats (Rattus norvegicus) exposed to carbon black with immunohistochemical technique. This study was a laboratory experiment with three treatment groups and seven replications using pregnant female white rats (Rattus norvegicus). Pregnant female rats were exposed to carbon black with a dosage of 523 mg/m3 and 1064 mg/m3 during pregnancy of day 6 up to day 11. The next phase was the observation and examination of the expressions of VEGF and MAPK by immunohistochemical staining toward placenta of the white rats exposed to carbon black. The result of the study showed an increase in the expression of VEGF in the placenta of the rats exposed to carbon black with a dosage of 523 mg/m3 and 1064 mg/m3 per inhale during the mid-period (6-11) of pregnancy. In addition, there was also an increasein the expression of MAPK on the placenta of the rats exposed to carbon black with a dosage of 523 mg/m3and 1064 mg/m3 per inhale during the mid-period (day 6-11) of pregnancy. In conclusion, the expression of VEGF and MAPK are increased along with the increased dosage of carbon black and age of gestation
