Abstract

Objective: (i) using a new non-invasive technique capable of evaluating quantitatively and qualitatively the haemoglobin content of the skin (ii) to evaluate delipidization induced by organic solvents. Patients: 11 Caucasians treated for 1 min in a randomized manner on the volar forearm with a mixture of chloroform/methanol (2:1) (CM) and ether/acetone (1:1) (EA) to delipidize the skin. Method: erythema was evaluated by computerized remittance spectroscopy immediately after delipidization and hourly for 2 h. Results: only CM application induced subjectively observed and objectively quantified erythema. Erythema was related to a significant increase in oxygenized haemoglobin content due to dilatation of arterioles in the subpapillary plexus (P
