Topic 2% minoxidil solution has been proved to be effective for hair regrowth in 30-40% of male pattern baldness in the United States and Europe. There was no report concerning topical minoxidil in Chinese patients, therefore, we selected 40 patients to investigate the efficacy and safety from December 1988 to January 1989. Those selected patients were consistent with male pattern baldness without systemic disease, and had never used topical hair regrowth agents. Patients applied topical medication 1 ml twice daily and were examined at 1 month intervals. Thirty two patients completed 6 to 12 months (average 9.6 months) of the study, moderate hair growth was found in 22% while minimal growth in 59% of the studied patients. All patients noted their shedding decrease after the application of drugs for 1 to 3 months. Scalp dryness and mild scaling appeared in 2 patients, but were tolerable. Before and after the trial, all patients had a chest roentgenogram, EKG, complete blood counts, urinalysis and blood chemistry studies, and no apparent abnormality was found. The efficacy of 2% minoxidil solution application in our study was less than that in the United States. which might be because some patients did not follow the application order regularly and a more strict evaluation standard was adopted in our series. However, the safety of no systemic adverse effect and the potential of inhibiting progressive shedding of hair were valuable as a topical drug.

[Significance of HLA-DR+ T cells and natural killer (NK) cells in the peripheral blood lymphocytes of alopecia areata (AA)]

HLA-DR+ T cell and NK cell subsets in peripheral blood lymphocytes of patients with AA were investigated. The percentages of HLA-DR+ T cell and NK cell subsets from a mild condition of patchy AA and an acute condition of alopecia totalis, for which hair regrowth occurred frequently with ease, were similar to those of the normal control. On the other hand, the percentages of HLA-DR+ Leu3a+ cells HLA-DR+ Leu2a+ cells and Leu7-Leu11+ cells from a severe condition of patchy AA and alopecia universalis, for which hair regrowth did not easily occur, were significantly higher than those of the normal control. The increase in the percentages of HLA-DR+ Leu3a+ cells, HLA-DR+ Leu2a+ cells and Leu7-Leu11+ cells from the severe condition of patchy AA and alopecia universalis was lessened and normalized by treatment with betamethasone. These findings suggest that the auto-immune disorders of HLA-DR+ T cell and NK cell may play important roles in disease activities related to severe patchy AA and alopecia universalis.

Alopecia areata: more on topical sensitizers.

Our experience on treating alopecia areata with topical sensitizers (diphencyprone, squaric acid dibutylester) is reported: staging, prognosis, side effects, follow-up, and psychological attitude of the patients towards this therapy and wigs are the focused aspects. The possible mechanisms of action of these allergens are discussed, reporting the case of a female patient with concomitant appearance of hair regrowth and psoriatic plaques in the same area after SADBE therapy.
