Korean Red Ginseng (KRG) has been reported to exert anticancer, anti-oxidant, and anti-inflammatory effects. However, there has been no report on the effect of KRG on skin pigmentation. In this study, we investigated the inhibitory effect of KRG on melanocyte proliferation. KRG extract (KRGE) at different concentrations had no effect on melanin synthesis in melan-A melanocytes. Saponin of KRG (...
The retention of particular genes after the whole genome duplication in zebrafish has given insights into how genes may evolve through partitioning of ancestral functions. We examine the partitioning of expression patterns and functions of two zebrafish kit ligands, kit ligand a (kitla) and kit ligand b (kitlb), and discuss their possible coevolution with the duplicated zebrafish kit receptors ...
Vitiligo is an acquired hypomelanotic disorder characterized by the absence of melanocytes. The mechanism melanocyte loss remains unclear. In this study, we aimed to explore underlying mechanism. By electron microscopy and immunohistochemistry, branching fragmented basement membranes (BM) were identified in vitiligo skin. To determine why BM was altered vitiligo, expression matrix metalloprotei...
The preputial glands in the rat are large modified sebaceous glands, which are believed to be the source of a sex pheromone (Gawienowski et al., 1975). Their main secretory product is neutral lipid, which contains an unusually high proportion of squalene as well as wax esters and glyceryl ether lipids (Nicolaides, 1965; Helmy & Hack, 1967). Like cutaneous sebaceous glands their secretion is hol...
Vitiligo is a common acquired disease of pigment loss. Though various non-invasive treatments (including local immunosuppression, ultraviolet light irradiation, etc.), transplantation cultured autologous melanocytes as cell suspension an emerging choice. An epidermal graft about 1cm2 was obtained by suction blistering from the abdomen patient, then dissociated into single cells and in different...
