전안부 빛간섭단층촬영계를 이용한 연성콘택트렌즈의 산소투과율에 따른 중심각막두께 변화 비교
송미령(Miryoung Song),채민병(Minbyung Chae),황제형(Je-hyung Hwang),김태진(Tae Jin Kim) 대한검안학회 2013 Annals of optometry and contact lens Vol.13 No.2
목적: 전안부 빛간섭단층촬영계를 이용하여 산소투과율이 다른 연성콘택트렌즈를 착용하였을 때 각막의 저산소 상태에서 산소투과율에 따른 중심각막두께의 변화를 비교하여 알아보고자 하였다. 대상과 방법: 건강한 성인 30명을 대상으로 렌즈를 착용하지 않은 눈을 대조군으로 하고 산소투과율이 낮은 렌즈와 산소투과율이 높은 렌즈를 각각 착용하여 눈을 감은 상태를 유지하면서 120분 동안 30분 간격으로 전안부 빛간섭단층촬영계를 이용하여 중심각막 두께를 측정하였다. 결과: 상피층의 두께 변화는 세 그룹 간에 유의한 차이는 없었지만, 기질층 두께의 변화에서는 산소투과율이 낮은 그룹이 다른 두 그룹에 비해 증가하였으며 30분마다 약 1%씩 통계적으로 유의한 증가를 보였다(p<0.05, ANOVA). 전체 각막 두께의 변화에서도 산소투과율이 낮은 그룹이 다른 두 그룹에 비해 유의하게 증가하였고 산소투과율이 높은 그룹과 대조군은 두 그룹 간에 유의한 차이가 없었다. 중심각막두께의 최종변화는 산소투과율이 낮은 그룹은 27.69 ± 9.36 um, 산소투과율이 높은 그룹은 15.07 ± 11.49 um로 산소투과율이 낮은 그룹이 산소투과율이 높은 그룹에 비해 유의하게 증가하였다. 결론: 전안부 빛간섭단층촬영계를 이용하여 저산소 상태에서 산소투과율이 낮은 렌즈가 산소투과율이 높은 렌즈에 비해 기질층의 부종을 통하여 중심각막두께를 증가시키는 것을 알 수 있었다. Purpose: With anterior segment optical coherence tomography(OCT), changes of central corneal thickness should be compared by contact lens oxygen transmissibility when wearing different soft contact lens under the corneal hypoxic and closed-eye condition. Methods: Control group is eyes which don t wear lens for 30 healthy adults. They wore lens with low oxygen transmissibility (Lens A) and lens with high oxygen transmissibility (Lens B). Central corneal thickness was measured by anterior segment OCT every 30 minutes maintained closed-eye during 120 minutes. Results: There was no significant change among the three groups for the changes of epithelial thickness. But, in the changes of stromal thickness, Lens A group was increased in comparison with other two groups and showed statistically significant increase of about 1% every 30 minutes (p < 0.05). In changes of the whole corneal thickness, Lens A group showed significant increase in comparison with other two groups and there was no significant difference between Lens B group and control group. In the final changing rate of the central corneal thickness, Lens A group was 5.07 ± 3.06% and Lens B group was 2.68 ± 1.67%. Lens A group showed more significant increased than Lens B group. Conclusions: Under the hypoxic condition, when wearing lens with low oxygen transmissibility for 120 minutes, central corneal thickness showed significant increase. And, usages of anterior segment OCT should be gradually increased for several diseases of various purposes because it can grasp with the whole anterior video under the condition wearing lens.

反應性染料의 着色拔染에 對한 顔料 및 拔染劑의 處理條件에 關한 硏究
宋美令 同德女子大學校 1984 同大論叢 Vol.14 No.1
For this study, colcor discharge was made of the discharge agent Emulsion paste following the dip dyeing by applying the reaction dyes to the cotton fabrics, and given steam heat treatment by printing it on dip dyed fabric, and then the spectrophotometer was used to find out dyeing effect depending on its respective density, through which the color differences were obtained, the clearness were compared with each other, light fastness and washing fastness were measured and the optimal discharge agent and treatment conditions were viewed. With the results of above process, the following phenomenon have been noticed. 1) It was found that the color blots with the thicker density of the discharge agent. The optimal density could be best obtained from Decroline 5%, Rongarite 10%, and Stannous chloride 3%. 2) The clearness measured by the spectrophotometer proved that Stannous chloride 3% and 30 minute heat treatment steaming showed 1.1 color differences, the best effect of color differences. 3) In the light fastness, the Stannous chloride was effective more than 5th grade in the color fastness. In the light fastness, the color in pigment was 1 grade better than the dip dyed fabric. 4) In the washing fastness, the dip dye4 fabric could obtained 4 grade better effect. However, the color in pigment is 1 or 2 grade lower in the Decroline and Rongalite, and the fabrics ironed by using of Yeomwhaje 1 suk showed 4 grade superior. 5) In preparation of color discharge paste gives a significant affection on Viscosity depending on the mixing process. And it is recommendable to following process in its preparation: color discharge-glycerine-pigment-emulsion in that order. with the result above, it was found that among the 3 color discharge paste, the Stannous chloride was superior in all the clearness, light fastness and washing fastness. Also it can be viewed that the Rongalite or Decroline were not so effective in the adherence of Emulsion. I wish to continue further studies on the scientific optimal conditions of the color discharge paste to contribute to the growth of dyeing industry.
