 Role of silis in esophageal cancer
 Ali Jabbari;Sima Besharat;Shahryar Semnani
 　　Association of silica with diseases like cancers has been determined previously. This study was designed to determine the quantity of silis in flour produced in Golestan Province, and its relation to esophageal cancer (EC). We took flour samples from all flour millings in Golestan Province. Base-melting method in nickel cruise was used at 550℃. The extract was reduced with acids. Different silis concentrations in various regions were compared. P < 0.05 was considered statistically significant. The median silis concentration was 0.0030 g, the mean silis concentration was 0.008760 ± 0.004265 g in each 100 g flour. The difference of mean silis concentrations in various regions was not significant. No high level of silica was found in the flour of Golestan Province. We could not find any significant difference in various areas between silica contaminations. Studies on the consumed bread and rice in various regions of Golestan Province can be helpful.
