    Summary: Chemical peeling is a well-known method used to restore a more youthful appearance and improve dermatologic defects. In recent years the technique has been marked by constant innovation. This book is the first atlas on chemical peels and has been significantly revised and updated since the first edition so as to reflect the state of the art in the field. The various types of chemical peel and peeling techniques, including new combined procedures, are first discussed in a step-by-step manner with the aid of supporting illustrations. Pathogenesis and treatment options are then considered, with each author reporting on his or her personal experience and preferred approach for different diseases and conditions, including acne, rosacea, melasma, photoaging, postinflammatory hyperpigmentation, actinic keratosis, and dark skin. An entirely new section addresses how to deal with side-effects and complications of the different procedures. This atlas has been specifically designed as a reference tool for dermatologists who deal with cosmetology. In particular, by providing clear and practical information on the different peeling procedures and their indications, it will prove invaluable for dermatologists and other doctors who wish to start performing chemical peels.

    Supernates of human T cells stimulated with TT antigen contain a factor that induces mitogenesis and immunoglobulin synthesis in autologous as well as allogeneic B cells. A fraction of the IgG produced has specificity against TT. The T-cell-derived LMF-TT eluted after albumin on Sephadex G 200 and did not contain immunoglobulin heavy chain determinants. LMF-TT was active on B cells from TT immune as well as TT- nonimmune individuals but in the latter instance the IgG secreted had no specificity against TT. B cells incubated with LMF-TT in the presence of a second antigen (DT) made IgG with specifity to that antigen provided the B-cell donor was immune to that second antigen. LMF-TT-containing supernates were depleted of TT antigen by Sephadex G 200 chromatography followed by passage over anti-TT immunosorbent columns. The antigen-free supernates were able to induce mitogenesis and IgG synthesis in B cells but the IgG produced failed to exhibit specificity against TT unless the TT antigen was readded to the B-cell cultures. The optimal concentration of LMF-TT (50 percent) inducing B-cell mitogenesis was different from the optimal concentration (20 percent) causing IgG synthesis by B cells. At low LMF concentrations (less than or equal 10 percent) addition of a second antigen to which the cell donor was immune caused an increase in the degree of B-cell mitogenesis. Submitogenic concentrations of LMF-TT (less than or equal to 5 percent) were still capable of inducingimmunoglobulin synthesis in B cells At these low concentrations of LMF-TT the proportion of anti-TT IgG over total IgG increased sharply. B cells from TT immune donors were separated on TT immunosorbent columns. Cells that bound to the column were more sensitive to the mitogenic and IgG synthetic effects of LMF-TT than unfractionated B cells. Thus, LMF is a nonspecific human T-cell helper factor which behaves like a polyclonal B-cell activator. However, in the presence of specific antigen (TT) the antigen-specific B cell is preferentially triggered by LMF. The experimental design of the present study does not rule out the additional presence of an antigen-specific helper factor in the supernates of TT-stimulated human T cells.
