Measurement of Phosphocreatine in Cutaneous Tissue by High Pressure Liquid Chromatography

A high pressure liquid chromatography technique for measuring phosphocreatine and adenine nucleotides in human cutaneous tissue is described. The presence of phosphocreatine in human skin was confirmed by this analytic method. Molar concentration of phosphocreatine and adenine nucleotides were determined in normal skin and in benign and malignant skin lesions. The preliminary results suggest that absolute amounts of phosphocreatine and adenine nucleotides and phosphocreatine/adenosine triphosphate ratios in malignant skin neoplasms and benign cutaneous lesions are different from those measured in normal nonischemic human skin.
