Whitening effects of cosmetics have been evaluated with change of skin reflectance of the colorimeter. However, skin color implies Hue (H) and Saturation (S) as well as skin reflectance (Value). We have developed a new evaluation method of change of skin color using computer analysis of the video-captured digital image. We have also investigated whitening effects of a new whitening cosmetic essence, 'Concentre anti-tache nuit' (CAN; Parfums Christian Dior, France), which contained 3% ...

We describe a case of photosensitivity due to pyridoxine hydrochloride (vitamin B(6)) in a heterozygote of hypophosphatasia. Photopatch tests using pyridoxine hydrochloride and pyridoxal 5'-phosphate, compounds referred to as vitamin B(6), with ultraviolet light A irradiation were positive. Laboratory examination showed low serum alkaline phosphatase. Tissue-nonspecific alkaline phosphatase exon amplification from DNA of the patient's lymphocytes detected deletion 1154-1156 ...
