The present study was carried out to evaluate the dermal toxicity of topically administered rice bran supercritical CO2 extract (RB-SCE; 500, 1,000, and 2,000 mg/kg) in male and female rats when given as a single dose and a 4-week repeated dose. In all rats that underwent the single-dose toxicity test, there were no abnormal changes in clinical signs or body weight and no deaths or abnormal gross necropsy findings related to RB-SCE. Based on the above results, the LD50 is >2,000 mg/kg in both sexes. In all rats that underwent the 4-week repeated dermal toxicity test, there were no abnormal RB-SCEassociated changes with respect to external signs, urine and blood, or organs. The no-observed-adverse-effect level (NOAEL) of RB-SCE was thus considered to be 2,000 mg/kg/day for both sexes and the target organ. RB-SCE can be regarded as a very safe agent for topical dermal administration at a moderate dose. © 2015, The Korean Society of Food Science and Technology and Springer Science+Business Media Dordrecht.

Rice bran oil extracted by supercritical CO2 extraction (RB-SCE) reportedly exhibits pharmacological activities such as antioxidant and in vivo hair growth-inducing effects. Such activities raise the possibility of the development of novel hair growth-inducing agents using RB-SCE. The aim of this study was to investigate the potential genotoxic effects of RB-SCE in three short-term mutagenicity assays (bacterial reverse mutation assay, in vitro mammalian chromosomal aberration test, and in vivo micronucleus assay). RB-SCE showed no genotoxicity in the bacterial reverse mutation assay up to 5000 mg/plate and in the in vivo micronucleus test up to 600 mg/kg body weight. However, at 120 μg/mL with S9 mix and 200 μg/mL without S9 mix RB-SCE showed significantly different genotoxicity than the negative control in the in vitro chromosome aberration test. The induction of chromosomal aberrations under the present conditions may have no biological significance. We have herein demonstrated that RB-SCE can be regarded as a non-genotoxic material based on the available in vivo and in vitro results. © 2014 The Pharmaceutical Society of Japan.

Provided is an optical treatment device for a scalp and a hair. According to the optical treatment device for the scalp and the hair, LEDs are mounted on a device to irradiate an ultraviolet light and visible light to the scalp and the hair, so that the metabolism of cells is activated. Iontophoresis equipment is mounted at the upper portion of the device or the lateral side portion of the device to apply the potential difference to the skin, thereby changing an electric environment of the skin, so that the transmittance of ionized medicine through the skin is increased. The optical treatment device includes a body, an MTS cartridge detachably provided at one side of the body, and an LED lamp interposed between the body and the MTS cartridge.

The purpose of this study was to develop a simple and effective method using conventional solvent extraction and antisolvent precipitation for the isolation of lycopene from Lycopersicon esculentum. A total of 100 grams of freeze-dried L. esculentum powder was weighed into a glass tube with a glass filter at the bottom. The material was extracted for 1 hour using 1 L of the following solvents: hexane, ethyl acetate, and ethanol. The extraction yields were 3.58, 4.39, and 1.25 mg/g, respectively, indicating that ethyl acetate was the most effective of the studied extraction solvents. Next, all carotenoids, except lycopene, were removed from the crude extract using an anti-solvent (methanol) salting-out method. The precipitated and isolated lycopene totaled 3.50 mg/g, indicating a 77.43% lycopene recovery rate. The lycopene isolation method developed in this study was more effective than the previous reported methods for the large-scale preparative isolation of lycopene.
