이경열,신경열,박천욱,이철헌 ( Kyung Ywal Lee,Kyung Yul Shin,Chun Wook Park,Cheol Heon Lee ) 대한피부과학회 1997 대한피부과학회지 Vol.35 No.3

Background: Sodium lauryl sulfate(SLS) is the most widely utilized model for studying acute and cumulative irritation. Sodium lauroyl glutamate(SLG) has exhibited a low irritation potential and an anti-irritating effect on other anionic surfactants. Objective : Our study was done to compare the skin irritancy of SLS and SLG using non-in- vasive techniques. Methods : Patches with 1% SLS and SLG solution were applied to the volar forearm of 20 healthy volunteers for 24 h. Finn chambers with 8mm(20pl) and 12mm(60pl) inner diameters were used. Visual scores, transepidermal water loss(TEWL) and an erythema(E)-index were measured at 30 min after removal of the patches, and every 24hours(h) up to 4 days. Results : The results are summarized as follows. 1. Visual scores were 0.20+0.30(8mm) and 0.73+0.34(12mm) at 24 h after removal of 1% SLS and were 0.15+0.29(8mm) and 0.30+0.41(12mm) at 24 h after removal of 1% SLG. They were increased at 30 min and 24 h after removal and decreased towards normal at 4 days after removal. By chamber size, the skin response with large Firin chamber(12mm) increased more significantly than with the small Finn chamber(8mm). In the small Finn chamber, there were no significant differences in the skin response between 1% SLS and 1% SLG. In the large Finn chamber, the skin response with 1% SLS increased more significantly than with 1% SLG. 2. TEWL values were 11.14+4.77(8mm) and 20.48+10.61(12mm) at 24 h after removal of 1 % SLS and were 10.38+3.99 and 14.87+7.46 at 24 h after removal of 1% SLG. They were increased at 30 min after removal and decreased towards normal 4 days after removal. By chamber size, their results were the same as the visual scores. Also, on comparison between 1% SLS and 1% SLG, their results were the same as the visual scores. 3. E-index was 10.05+2.70(8mm) and 11.15+2.56(12mm) at 24 h after removal of 1% SLS and was 10.15+2.16 and 10.60+2.26 at 24 h after removal of 1% SLG. They were increased at 30 min after removal and decreased towards normal 4 days after removal. By chamber size, their results were the same as the visual scores. In the small and large Finn chamber, there were no significant differences in the skin response between 1% SLS and 1% SLG. Conclusion : SLS is more irritating than SLG. The large Finn chamber may be more suitable to yield positive irritant reactions than the small Finn chamber. Also, TEWL measurements may be a more accurate and sensitive method than the E-index.

Tape Stripping과 Sodium Lauryl Sulfate에 의한 피부 장벽기능의 손상 및 회복에 관한 연구

신경열(Kyung Yul Shin),박천욱(Chun Wook Park),이철헌(Cheol Heon Lee) 대한피부과학회 2000 대한피부과학회지 Vol.38 No.2

N/A Background:The main function of the stratum corneum is to serve as a barrier preventing the penetration of irritants and transepidermal water loss (TEWL). Previous studies have shown that the cutaneous barrier disruption by application of acetone or sodium lauryl sulfate (SLS) and tape stripping leads to various metabolic changes. Recent studies showed that there was some difference in the recovery rate between tape-stripped groups and acetone-treated groups, and an individual irritant not only exerted rather specific morphologic effects on the cellular components of the keratinocyte but also induced distinct morphological alterations of the different components of the stratum corneum. In other words, this data suggested that individual irritants could show different cutaneous barrier recoveries. Objective:This study was done to compare the recovery rate after cutaneous barrier disruption between a tape-stripped group and a SLS irritated group, and to test the relationship among baseline TEWL, TEWL after the SLS irritation, recovery of TEWL, and number of strippings needed to increase TEWL up to 20g/m2/h. Methods:The permeability barrier of normal human skin was disrupted by tape stripping and patch of SLS and the recovery rate was assessed by measure of TEWL and erythema (E-) index. Results:The number of tape strippings needed to increase TEWL up to 20g/m2/h was 32.7±9.6 (20-50). The recovery rate of TEWL was 56.85±17.97% twenty-four hours after tape stripping and (Korean J Dermatol 2000;38(2):183~190)

These experiments were performed to investigate the purification, the characteristics and the hydrolysis products on various Polysaccharides and oligosaccharides of thermophilic α-amylase produced by Bacillus licheniformis IAM 11054. The optimum culture time, the optimum initial pH and the optimum culture temperature for the production of α-amylase were 72hrs, pH 6.5 and 40℃, respectively. The crude enzyme was purified to 568- fold by starch adsorption, ammonium sulfate fractionation, DEAE-cellulose column chromatography and CM cellulose column chromatography. The specific activity of the purified enzyme was 312.5u /mg ㆍ protein and the yield of enzyme activity was 13.0%. The purified enzyme showed a single band (relative mobility 0.25) on polyacrylamide gel electrophoresis and the molecular weight was estimated to be approximately 145,000 by SDS-polyacrylamide gel electrophoresis, and isoelectric point was pH6.0. The optimum pH, the stable pH range, the optimum temperature and the stable temperature of the purified enzyme were pH6.0∼7.5, pH6.0∼10.5. 80℃ and below 75℃, respectively. The purified enzyme was greatly inhibited by Hg++ Ag+ and I2, and the thermostability of it was greatly increased by Ca++. The purified enzyme hydrolyzed soluble starch, corn starch, glutinous rice starch, green banana starch, arrow root starch, potato starch, yam starch, oyster glycogen, maltopentaose and maltohexaose, but did not hydrloyze α, β, γ -cyclodextrin, pullulan, maltose, maltotriose, maltotetraose, raffinose, lactose and sucrose. The purified enzyme hydrolyzed various starch to G1, G2, G3, G4, G5, G6 and others, and G5 to G2 and G3 and G6 to G1, G2, G3, G4 and G5. Among various gelatinized starches, potato starch and green banana starch were favorably hydrolyzed by the purified enzyme.
