Abstract: Xylene is an important component of petrol and a widely distributed environmental contaminant. About 98% of Xylene is derived from the petrochemical and petroleum refining industries. When human get expose to xylene, which is one of the major Geno toxicants, may be associated with a range of acute/chronic diseases and cancer still literature is not available. Taking into our mind that occupational exposure to such derivatives may possess genotoxic risk or not. Hence our study aims to investigate and correlate the cellular changes in exfoliated oral epithelial cells oral smears with urinary methyl hippuric acid level estimation in petrol pump workers and to identify the significant role of xylene on oral mucosa.
Materials and Methods: Urine samples and oral buccal mucosa smears were collected from 30 healthy individual (control) and 30 petroleum pump workers (case) working in petroleum station who are above 18 years of age. The urine was collected before exposure/work shift and after completion of work shift. The urinary methyl hippuric acid (MHA) level was analyzed by using Shimadzu UV-Visible Spectrophotometer procedure. The smeared slides were stained with PAP stain and analyses the cytomorphometric changes of exfoliated epithelial cells by using Axio Vision SE64 Rel 4.9.1. Ink Software.
