The comparative detergency of Sodium dodecyl sulfate (SDS) solution near the first critical micelle concentration (CMC) was measured by means of a 131 I-labelled castor oil as a soil. More than 95% radiochemical purity of 131 I-labelled castor oil was obtained using potassium lidide as a carrier. Polyester test fabric was soiled with 131 I-labelled castor oil, and washed in a conventional washing apparatus mounted on appropriate devices. Fabric radioactivities were measured before and after washing by a scintilation counter. Near the first CMC, the detergency of SDS was increased with decreasing of surface tension of SDS. It was also shown that 131 I-labelled castor oil was useful for studying the detergency of SDS.

We have used a novel liquid surface forces apparatus to determine the variation of disjoining pressure with film thickness for dodecane-water-dodecane emulsion films. The LSFA allows measurement of film thicknesses in the range 5-100 nm and disjoining pressure from 0-1500 Pa. Disjoining pressure isotherms are given for films stabilised by the nonionic surfactnat n-dodecyl pentaoxyethylene glycol ether$(C_{12}E_5)$ and n-decyl-$\beta$-D-glucopyranoside($C_{10}- $\beta$-Glu)$ and the anionic surfactant sodium bis(2-ethylhexyl) sulphosuccinate(AOT) in the presense of added electrolyte. For $C_{12}E_5$ and AOT, the emulsion films are indefinitely stable even for the highest concentration of NaCl tested (136.7 Nm) whereas the $C_{10}-{eta}-Glu$ film shows coalescence at this salt concentration. For film thicknesses greater than approximately 20 nm with all three surfactants, the disjoining pressure isotherms are reasonably well described in terms of electrostatic and van der Waals, forces. For the nonionic surfactant emulsion films, the charge properties of the monolayers are qualitatively similar to those seen for foam films. For AOT emulsion films, the monolayer surface potentials estimated by fitting the isotherms are similar to the values of the zeta potential measured for AOT stabilised emulsion droplets. For thin emulsion films certain systems showed isotherms which suggested the presence of an additional repulsive force with a range of approximately 20 nm.

This Study was performed to get the suitable oil dispersion agent by assessment of color strength of organic pigment in non-aqueous systems. Organic pigment is used as a color expression material with other body pigments in the make-up products. But occasionally aggregation or agglomeration occurs for the lack of affinity with medium, This function is the cause of disturbing homogeneous dispersion, and then bring about an instability of products. Our study, research of dispersion mechanism between the pigment and oil phase, has been executed to solve this problem, and find a oil dispersion agent having optimum dispersion condition. Generally dispersion is related to between the solid-liquid mutual properties and electrical phenomena associated with solid-liquid interface. This factor is determined to input energy, milling time, optical properties, particle size, rheological properties, etc. Ideal dispersion state is told that coloring primary solid particle is homogeneously dispersed in medium. Good dispersed colorants are strongly and clearly appeared. We are already known that the particle size of organic pigment, chemical properties and viscosity of medium, refractive index. Consequently We determine the affinity of medium and organic pigment by measuring of color strength in the same mechanical condition. UV-VISIBLE RECORDING SPECTRO PHOTOMETER is used for measuring apparatus. We can decided the dispersion level of oil dispersion agent by measuring absorbance of color strength in the visible range that diluted medium for colloid colorant particles.

Telecanthus is a common symptom accompanied by Waardenburg syndrome, a rare genetic disorder. The optimal surgery for telecanthus correction is still debated. A 28-year-old patient with Waardenburg syndrome underwent transnasal wiring canthopexy using a Y-V epicanthoplasty for telecanthus correction. A Mini-Monoka stent was used to prevent damage to the lacrimal apparatus. The intercanthal distance decreased from 50 mm to 43.2 mm. The easily designed Y-V epicanthoplasty incision provides sufficient operative field for oblique transnasal wiring, which is effective in properly positioning the medial canthal tendon. It has minimal scarring resulting in satisfactory cosmetic outcomes.

Real-time measurements of skin movement induced by air blown on the surface was measured with time. We investigated age-related changes in displacement of the skin surface on the face or the inner upper arm caused by air on 98 Japanese women volunteers aged from 10 to 70 years old. The maximum distance (the denting state) that the skin moved reached 2-5 mm within 10-15 msec on the cheek skin. After that, the skin generally recovered to the original state within 40-50 msec. The maximum speed of movement was 0.5 m/sec and the recovery speed was about 0.25 m/sec on the cheek skin. Significant changes with age were not observed in the denting state, but a significant correlation with age was observed in the recovery state. For example, the maximum recovery speed decreased significantly with age (p=-0.568, p<0.001) and the time required for recovery increased significantly with age (p=0.561, p<0.001). Although the inner upper arm also showed similar results to a cheek, a few parameters were different. This apparatus is a more practical macroscopic system for evaluating skin mechanical properties without contact. This apparatus is effective not only for measuring the mechanical properties of facial skin but also of body skin, such as swelling or sagging of body parts.

Background: Along with the increase in consumer interest in and consumption of tattoo products, the controversy over harmful heavy metals associated with the use of tattoo cosmetics is also increasing. Therefore, investigation of hazardous metals in these tattoo products is needed. Objectives: This study was performed to provide useful data for establishing reasonable standards to securely manage tattoo cosmetics, tattoo stickers, and tattoo inks distributed in the market. Methods: Thirteen kinds of hazardous metal contents (Pb, As, Cd, Sb, Ni, Co, Cu, Cr, Se, Ba, Zn, Sn, and Hg) were analyzed for 23 tattoo cosmetics, ten tattoo stickers, and 16 tattoo inks. Hg was measured through the combustion-gold amalgamation method, and other hazardous metals were measured by inductively coupled plasma-mass spectrometry (ICP-MS) after acidic decomposition using a microwave apparatus. Results: The detected ranges of Pb, As, Cd, Sb, Ni, and Hg in tattoo cosmetics were 0.07~1.18, 0.06~0.41, ND~0.07, 0.01~3.44, 0.12~2.75, and ND~0.01 ㎍/g, respectively. All of the hazardous metals detected were below the recommended maximum standards of the Ministry of Food and Drug Safety. The mean amount of Pb detected in tattoo stickers for children was 0.24 ㎍/kg and Cd was not detected, meaning both metals met the recommended criteria. There was no statistically significant difference in all measured metals between children's tattoo stickers and adults' tattoo stickers. In the results of the study on the hazardous metal content of tattoo inks, four products (25%) for Pb, one product (6%) for As, 13 products (81%) for Ni, four products (25%) for Cu, and five products (31%) for Zn exceeded the recommended standards approved by the government. The highest predicted exposure amount for hazardous metals exceeding the recommended level of tattoo inks in a single tattooing was 5.69 ㎍/kg for Ni, 8.51 ㎍/kg for Zn, 0.44 ㎍/kg for Pb, 8.07 ㎍/kg for Cu, 0.44 ㎍/kg for As, and 71.36 ㎍/kg for Ba. Conclusions: It is necessary to prepare criteria for content limitation for the management of Co, Cr, Ba and Se tattoo cosmetics, and tattoo inks require thorough quality control.

Purpose: Failure of proper migration, fusion, or maturation of the branchial apparatus components results in a variety of congenital defects. Of these, cartilaginous rests are infrequent, while branchial cysts and sinuses are more common, relatively. The purpose of this study is to examine the clinical and pathological features of rare cervical branchial remnants in order to provide basis for its correct diagnosis and treatment. Methods: We report three cases of cervical branchial remnants which were treated in our hospital from December 2004 to December 2009. These cases were examined their clinical features, histologic findings and treatments. The patients had been operated with simple excision, excision of the combined components and preoperative antiboitics. Results: A retrospective review produced 2 cases of the cervical branchial remnants and 1 case of the cervical chondrocutaneous branchial remnant. All cases were on the left side of the neck, and anterior to the sternocleidomastoid muscle. Histopathological examination showed that fistula & sinus were lined with stratified squamous epithelium, additionally, they were consisted of a cutaneous envelope containing sebaceous glands, hair follicles, various amounts of adipose tissue, and elastic fibers. And, One case revealed containing hyaline cartilage. No patient developed complications or reccurences. Conclusion: The authors recommend simple surgical excision of the remnants when discharge, infection, or cosmetic problem occur. Finally, these lesions do not have fistulous tracts or connections with important, deeper organs, and so can be safely transected at the level of the superficial musculature.
