In recent times, the demand for edible medication for the treatment of hyperpigmentation has increased significantly. Therefore, the discovery of a stable, safe and inexpansive antimelanogenic component from natural substances, such as grains, is of particular interest. The levels and activities of some metabolites and/or enzymes can be increased. In the present study, we investigated the antimelanogenic effects of water-soluble extracts from barley (BE), malt (ME) and germinated barley (GBE) in melan-a cells. The inhibitory effects of ME and GBE on melanin production were significantly greater than that of BE. Interestingly, the content of ferulic acid, the proposed active component of barley, was also higher in ME and GBE than in BE by HPLC analysis. Western blot analysis of the expression of melanogenic enzymes in melan-a cells treated with BE, ME or GBE indicated the expression of both tyrosinase and tyrosinase-related protein 2 (TRP-2) significantly decreased after treatment with BE, ME or GBE. These results suggest that besides BE, ME and GBE also inhibit melanin production most likely through suppression of tyrosinase and TRP-2 expression. ME and GBE were more efficacious at inhibiting melanin production than BE was and may also represent potential skin-whitening agents.

Natural products have received revived interest via traditional remedies or alternative medicine used for the treatment of various diseases. Zanthoxylum piperitum (ZP) has been utilized in traditional medicine for various medicinal purposes. The present study was conducted to evaluate whether ZP modulates allergic inflammation both in vivo and in vitro. We examined the pharmacological effects of ZP on 2, 4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD) symptoms in mice. Additionally, in order to clarify the anti-inflammatory mechanisms of ZP, we elucidate the effect of ZP on the expression levels of inflammatory cytokines and nuclear factor-κB (NF-κB) in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). The results demonstrated that ZP attenuated AD clinical symptoms such as erythema, edema and dryness as well as histamine and IgE serum levels in DNCB-induced AD model mice. Additionally, ZP suppressed the expression of inflammatory cytokines and activation of NF-κB in AD-like skin lesions and stimulated HMC-1. These results provide experimental evidence that ZP may be useful candidate for treating allergic inflammation including AD.

Surfactants which have ability to decrease surface tension through surface activation between the interfaces are used as essential major raw materials for detergents and cosmetics. Typical synthetic detergents such as EO (ethylene oxide), LAB (linear alkylbenzene) are made from chemical surfactant derived from petrochemicals, therefore, they are responsible for major environment contaminations and ecosystem destruction, especially of rivers and also cause atopic dermatitis through strong skin stimulus of these small molecular's powerful permeability and lead to cancers if they get into organs through capillary. Now worldwide interest is increasing to develop new natural surfactants and biosurfactants as ecological, biodegradabl, harmless and multi-functional new amphiphillic materials which replace these synthetic surfactants.

As a dental technician, the aim of the present study on maxillofacial prosthesis was to research its relation with dental technology and further development aspects by looking into its history, kinds, production materials and process. Dental technicians are to expect a great potential to work as maxillofacial prosthetist if having an interest in education of maxillofacial prosthesis field, and developing and operating the education process by expanding the range of dental technology. This article is to present overall history of maxillofacial prosthesis and some background information on the materials which have been used from the past. The maxillofacial field plays essential functions of mastication and speech, as well as performs appearance, which evokes good or bad feelings as an instant and instinctive response. The use of maxillofacial prostheses is not merely the replacement of a missing part of the face, resulted from injuries, but a rehabilitation process to help individuals come back to society. Rehabilitation includes both patient's physical and psychological recovery, such as self-esteem and selfconfidence. There has been a rapid development in application potentials of maxillofacial prosthesis technology which include implant, which can penetrate skin, and new materials. In order to produce maxillofacial prosthesis, general procedures of maxillofacial laboratory work should be understood first. Maxillofacial prosthesis and the dental prosthesis have many similarities in its academic perspective and originality. Maxillofacial prosthesis should be added into the curriculum for dental technology to achieve co-enhancement of the two fields.
