Influence of topically applied betamethasone-17-valerate on cell cycle kinetics of human anagen hair determined by DNA flow cytometry.

In 47 healthy volunteers betamethasone-17-valerate (0.1% solution and cream) was topically applied twice daily on the scalp skin. After 7 and 14 days treatment, anagen hairs were plucked in each volunteer from both treated and untreated contralateral scalp areas. Cell cycle analysis of plucked anagen hairs was performed by means of DNA flow cytometry. Already after topical betamethasone-17-valerate application for 7 days, cell kinetic changes were found showing a slightly significant decrease of S and G2 + M cell percentages and a significant increase of G0/1 cell percentages. The present study demonstrates the possibilities of DNA flow cytometry to study the pharmacological effects on cell kinetics of plucked human anagen hairs.

[DNA impulse cytophotometric studies of the modification of the proliferation behavior of the outer hair root sheath by topical glucocorticoid administration].

A corticoid preparation (C) was topically applied on the scalps of 47 healthy test persons for 7 or 14 days, resp. After this treatment, we plucked anagen hairs under standardized conditions both from the area treated with C and the contralateral, untreated area. The proliferative activity of plucked anagen hairs with root sheaths was analyzed by means of DNA flow cytometry. Already a 7 days treatment with topical C resulted in kinetic changes of the outer root sheath: The percentage of the cells in the G1/10-phase of the cell cycle was increased, whereas that of the cells in the S-phase and the G2+M-phase was decreased.
