Silica nanoparticles (NPs) are widely applied in many fields, such as chemical industry, medicine, cosmetics, and agriculture. However, the hazardous effects of silica NPs exposure are not completely understood. In this study, the two different sizes (20 nm and 100 nm) and different charges (negatively charged [NC] and weakly negatively charged [WNC]) of(More)
Zinc oxide (ZnO) nanoparticle is added in various materials and products such as paints, plastics, ceramics, glass, rubber, pigments and sunscreen. Especially, ZnO nanoparticles are widely used in UV protection, because of their property of absorption ultraviolet light. Despite the widespread use of ZnO nanoparticles, there are many unknowns in(More)
In spite of widely use of zinc oxide (ZnO) nanoparticles (NPs) in cosmetic industry and in our daily lives, insufficient studies have evaluated the potential of their toxic response. This study was conducted to investigate the potential of cytotoxicity induced by ZnO NPs, especially influences of the surface charge and different particle size. Assessment of(More)
In order to determine the efficacy of functional foods, objective measurement of the severity of atopic dermatitis (AD) after taking foods is important. The aim of this study was to conduct an objective evaluation of whether Korean red ginseng (KRG) might be helpful for improvement of skin condition and serum IgE in patients with AD. Thirty atopic patients(More)
PURPOSE This study examined the need for public communication about nanotechnologies and nanoparticles by providing a comparative analysis of the differences in risk awareness of nanotechnologies and nanoparticles between consumers and experts. METHODS A total of 1,007 consumers and 150 experts participated in this study. A questionnaire was prepared(More)
Nanoparticles (NPs) are used commercially in health and fitness fields, but information about the toxicity and mechanisms underlying the toxic effects of NPs is still very limited. The aim of this study is to investigate the toxic effect(s) of 100 nm negatively (ZnO(AE100[-])) or positively (ZnO(AE100[+])) charged zinc oxide (ZnO) NPs administered by gavage(More)
This study was undertaken to investigate the potential toxicity and establish the no observed adverse effect level (NOAEL) and target organ(s) of negatively charged colloidal silica particles of different sizes, ie, SiO2 (EN20(-)) (20 nm) or SiO2 (EN100(-)) 2(100 nm), administered by gavage in Sprague-Dawley rats. After verification of the physicochemical(More)
Alopecia areata (AA) is an autoimmune disease that can affect any hair-bearing area. AA is known to be caused by immunological disorder but still, the pathogenesis is not fully understood. Many therapeutic modalities have been used to treat alopecia areata, with variable efficacy and safety profiles. Unfortunately, none of these agents is definitely(More)
BACKGROUND Topical calcineurin inhibitors (TCIs) have been successfully used to treat seborrheic dermatitis (SD) patients. Meanwhile, treatment of atopic dermatitis (AD) with low-dose, intermittent TCI has been proved to reduce disease flare-ups. This regimen is known as a maintenance treatment. OBJECTIVE The aim of this trial was to investigate the(More)
BACKGROUND Since the treatment guidelines for atopic dermatitis (AD) were released by the Korean Atopic Dermatitis Association (KADA) work group in 2006, there have been several advances in AD management. OBJECTIVE We aimed to establish updated evidence- and experience-based treatment guidelines for Korean AD. METHODS We collected a database of(More)
