Linoleic Acid Levels in Arsenical Palmar Keratosis

Chronic arsenic exposure can lead to palmo-plantar keratosis. In the stratum corneum, linoleic acid is responsible for inflammation, keratinization, regeneration etc. The aim of this study was to understand the role of linoleic acid in pathophysiology of arsenical keratosis. Lipid extracts were collected from keratotic lesions of patients, arsenic exposed and non-exposed controls (all seven in number). Linoleic acid levels were estimated by RP-HPLC. The data were expressed as mean SE. There was significant (P
