Abstract: Method for diagnosing a cellular aging or inflammation condition of keratinocytes of the skin or a pilous follicle in a person, or for diagnosing the efficiency of a treatment intended to combat said condition. To this effect, the concentration or activity of certain markers (catalase, glutathion or glutathion peroxydase) is compared in the keratinocytes suspected of being pathological and the keratinocytes of a reference non pathological area. The pathological condition intensifies the activity of the catalase, or reduces the activity of other markers. Application particularly to the diagnosis of alopecia, and to the estimation of the efficiency of a treatment of baldness with minoxidil in a given individual.

Abstract: This biosensor comprises a membrane (8), in which an enzyme catalyzing the transformation of a substrate used in the cutaneous metabolism is immobilized, means for detecting and measuring a phenomenon caused by said transformation, which is representative of the concentration of the substrate to be measured, with said substrate being brought into contact with the enzymatic membrane (8), and a measuring cell (13), a wall area of which is formed by the membrane (8) and which is capable of being closed, during the measurement, by a cutaneous covering area (15), with the cell (13) being combined with means for making circulate therein a liquid for placing in solution the substrate to be measured. For the measurement, the biosensor is applied to the skin, the buffer is injected into the cell and, once said cell is filled, the detection and the measurement are carried out, then the buffer is again made to circulate in order to remove the solubilized substrate.

Abstract: A process for stimulating the growth of epidermis cells.The epidermis cells are contacted with an aqueous saline extract (RE) of ocular tissues. The process is especially applied for human epidermis cells.Application to the study of chromosomes of the human epidermis cell, particularly for the detection of natural or induced chromosome anomalies, and to the production of grafts, and especially autografts, usable on man, for example in the treatment of burns, cosmetic and diagnostic products.
