...J. Borovanskỳ; J. Duchoň The chemical composition of isolated human hair melanosomes was studied. It was found that hair melanosomes contained 60.54 ± 3.99% of melanin which puts them among the most melanized particles. The amino acid analysis revealed all 18 usual amino acids in the hydrolysate...

.... Moreover, there were much fewer melanocytes and melanosomes in the epidermis of both lesions. The corneal layer of the brown papules was far thicker than that of the leukoderma. Therefore, the thick corneal layer of the brown papules may prolong the retention of a few melanosomes or a little melanin...

...Akira Ichikawa; Hidemi Takagi; Koichi Suda; Takashi Yao Background: During melanogenesis, the activity of tyrosinase (the key enzyme for melanin synthesis) is important in the diagnosis of melanomas. Methods: Nine samples were included in this study, based on the availability of four malignant...

... more melanin, this could promote the formation of a melanin-minocycline complex, which could explain the severe and prolonged DRESS which may occur in this subgroup of patients. We researched the variant sequence that corresponds to a 2-extra-nucleotide insertion (TA) within the TATA box resulting...

...) is a noncytotoxic inhibitor of melanin production in cultured B16 melanocytes. It was further demonstrated that the topical application of 5% MMI on brown guinea pig skin for 6 weeks causes a significant reduction in the amount of epidermal melanin, resulting in visually recognizable cutaneous depigmentation...

... (6.4%), has a higher skin-depigmenting potential than RA 0.05% in the tail skin of C57BL/6 mice. This effect was observed in reducing the number of functioning melanocytes and/or in inhibiting their ability to synthesise melanin. In addition, the visually recognisable depigmenting effect of RALGA...

... plantar warts. We report a 51-year-old Japanese female with a HPV-60-induced plantar wart which showed the clinical appearance of both pigmented and ridged warts. Masson-Fontana staining revealed increased melanin granules in the epidermis of the wart. This observation suggests that HPV-60 may...
