Purpose: To investigate the difference in donor corneal cell changes after penetrating keratoplasty in various corneal diseases. Methods: Subjects included 36 eyes from 35 people with at least 6 months of follow-up who had undergone penetrating keratoplasty between August 2000 and December 2002. The patients were classified into three groups based on the state of the corneal endothelium. Changes in cell density, polymorphisms, and polymegathism of the donor cornea were compared between groups. Results were analyzed by ANOVA. Results: The overall corneal endothelial cell density after grafting was lower, but the differences in endothelial cell states between the recipient cases were not statistically significant. The change in corneal endothelial cell density showed a significantly higher difference (p=0.0013) when patients had either undergone a rejection episode during recovery or recurred herpetic uveitis. Conclusions: The preoperative state of the corneal endothelium may affect the survival of donor corneal endothelium after grafting. However, rejection of the transplant contributes more significantly to the survival of the donor corneal endothelium than other factors. We suggest close observation and keen therapy with respect to rejection after grafting.

Purpose: To access the effect of phacoemulsification, using Neosonix? (Alcon Laboratories, TX, USA), on the cornea and lens opacity. Methods: This study involved 42 eyes of 37 patients who underwent phacoemulsification using the Neosonix from December 2005 through March 2006. We measured the density and the thickness of lenses using a Scheimpflug camera and evaluated the correlation between the density and the phaco time. To evaluate the effects of Neosonix? on the corneal endothelium, we measured various corneal endothelial cell parameters, including corneal endothelial cell density, corneal thickness, and morphologic changes up to two months postoperatively. Results: The preoperative mean values of lens density for the anterior cortex, nucleus, and posterior cortex were 105.86±34.99 CCT, 82.17±35.14 CCT, and 77.88±52.98 CCT, respectively. The mean phacoemulsification time was 48.67±29.79 seconds and increased significantly, according to the increase of the densities of the lens nucleus and cortex (p<0.01). Postoperative mean corneal endothelial cell density was 2741±474 cell/mm2 at one day, 2757±447 cell/mm2 at one month, and 2765±422 cell/mm2 at two months. Corneal endothelial cell loss was 4.39%, 3.83%, and 3.56% at one day, one month, and two months postoperatively, respectively. There was no statistically significant difference between the preoperative and postoperative values of corneal endothelial cell density (p>0.05). Conclusions: The phacoemulsification time using oscillation device significantly increased as the density of the lens cortex and nucleus increased, and there was no statistically significant difference between the preoperative and postoperative values of corneal endothelial cell density.

Background: Smartphone usage time has been increasing every year causing smartphone addiction, also known as cell phone dependency. This study investigated and analyzed the effects of family characteristics on adolescent smartphone use. Methods: The subjects were 908 middle school students in Gangneung whose legal guardians agreed to participate in the study. We investigated general characteristics, family structure, smartphone usage time of family members, using Korean Smartphone Addiction Proneness Scale (K-SAPS), Family APGAR, and Family Adaptability and Cohesion Evaluation Scale III (FACES III). The participants were classified into three groups according to the scores of the SAPS: addiction proneness, addiction tendency group, and normal user. Results: The prevalence of the addiction proneness group was 47 (5.2%). The K-SAPS scores were higher in the following categories: female (P<0.001); more monthly allowance (P<0.05); lower academic performance (P<0.001); fewer hours of exercise (P<0.001); longer smartphone usage time (P<0.001); and younger owners of smartphones (P<0.05). In family characteristics, the K-SAPS scores were significantly higher in single parent families (P<0.05), longer smartphone usage time of mother and siblings (P<0.05), less time spent watching TV with family members (P<0.05), more exposure to smartphones in childhood (P<0.05), and less time spent with mother (P<0.05). The K-SAPS scores were significantly higher when family APGAR, family adaptability, and cohesion scores were lower (P<0.001). Conclusion: This study indicated that the smartphone addiction in middle school students is closely related to smartphone usage of family members and family functions. Therefore, family behavior that can be corrected should be considered for counseling to prevent smartphone addiction. 연구배경: 중학생에서 다른 연령대에 비하여 스마트폰 이용 시간이 가장 긴 것으로 보고되었다. 스마트폰 사용의 증가는 습관적 의존으로 대표되는 중독 문제를 일으킨다. 이에 본 연구는 청소년의 스마트폰 중독에 미치는 가족의 영향을 알아보고자 하였다. 방법: 강릉 지역의 4개 중학교 전교생 중 학생과 법적 보호자가 본연구에 동의한 908명을 대상으로 하였다. 연구 대상자의 일반사항 및 가족의 구조적 특성, 스마트폰 사용 시간, 청소년 스마트폰 중독 위험 자가진단척도, 가족기능점수등을 조사하였다. 연구 분석은 스마트폰 중독 위험 자가진단척도에따라 중독위험군, 중독성향 일반 사용자 군, 일반 사용자 군으로 나누어 분석하였다. 결과: 스마트폰 중독 위험 자가진단척도에 따른 중독위험군은 47명(5.2%) 중독 성향 일반 사용자 군은 194명(21.6%)이었다. K-SAPS점수는 남학생보다 여학생에서(P<0.001), 학업성적이 낮을수록(P<0.001), 운동 횟수가 적을수록(P<0.001), 용돈액수 5만 원 이상에서(P<0.05), 일찍 스마트폰을 가질수록(P<0.05), 본인의 사용 시간이 길수록(P<0.001) 높았다. 가족특성을 살펴보면, 편부모가정일 때(P<0.05), 어머니와 형제자매의 스마트폰 사용 시간이 길수록 (P<0.05), 어머니와 함께 지내는 시간이 적을수록(P<0.05), 가족과 함께 TV를 보는 시간이 적을수록(P<0.05), 유년기에 스마트폰에 노출된 경험이 많을수록 (P<0.05) 스마트폰 중독 척도 점수가 높게 나타났다. 가족기능과의관계에서는 가족기능이 낮고, 가족과 이탈하여 소외되어 있을수록, 가족의 적응력이 낮고 경직되어 있을수록 스마트폰 중독점수가 유의하게 높았다(P<0.001). 결론: 본 연구를 통해 중학생의 스마트폰 중독 성향은 가족의 스마트폰 사용 및 가족의 기능과 밀접한 연관성이 있음을 확인하였다. 향후 스마트폰 중독 예방을 위한 상담 시 가족의 영향을 고려 할 것을 제언한다.

Purpose: To evaluate the correlation between the conventional method and the clinical history method those determine intraocular lens (IOL) power for cataract surgery in eyes with prior laser in situ keratomileusis (LASIK) in the absence of pre-LASIK data. Methods: The medical records of 200 eyes in 100 patients who had been treated with LASIK for myopia and were followed up for more than 6 months were reviewed. The IOL powers by conventional method using post-LASIK keratometric value and by clinical history method were compared. Results: The mean values of IOL powers by conventional method, and by clinical history method were +20.00±1.48D (+13.74~+23.23D) and +20.79±1.28D (+17.27~+24.32D), respectively. The following equation describes the regular relationship between the two methods: IOLCHM (clinical history method)=0.708*IOLCM (conventional method) +6.624 (r=0.816, p<.01). Conclusions: This equation may offer more accurate IOL power for cataract surgery in eyes with prior LASIK surgery in the absence of pre-LASIK data.

Methods: This study comprised 47 eyes of 43 patients having phacoemulsification with the AquaLase?. Various corneal endothelial cell parameters, including corneal endothelial cell density, corneal thickness and morphologic change, were evaluated up to 2 months postoperatively. Results: Preoperative mean corneal endothelial cell density was 2818±282 cell/mm2. Postoperative mean corneal endothelial cell density was 2682±390 cell/mm2 at 1 day, 2701±263 cell/mm2 at 1 month and 2721±396 cell/mm2 at 2 month. Corneal endothelial cell loss was 4.74%, 4.00% and 3.55% at postoperative 1 day, 1 month and 2 months respectively. There was no statistically significant difference between preoperative and postoperative corneal endothelial cell density (p>0.05). The corneal endothelial cell loss was not increased even though the phacoemulsification time with the AquaLase? was increased (p>0.05). Preoperative mean corneal thickness was 559.4±37.4 ?m. Postoperative mean corneal thickness was 586.9±35.1 ?m at 1 day, 573.3±30.1 ?m at 1 month and 554.9±26.7 ?m at 2 month. There was a significant increase in corneal thickness at postoperative 1 day (p=0.001). However, there was no statistically significant difference of corneal thickness between preoperative and postoperative 1 month and 2 month (p>0.05). Conclusions: The phacoemulsification with the AquaLase? dose not cause the significant corneal endothelial cell density and corneal thickness change postoperatively.

안세연 ( Seyeon Ahn ),길소연 ( Soyeon Gil ),권오선 ( Ohsun Kwon ),장윤희 ( Yunhee Chang ),진무현 ( Mu Hyun Jin ) 대한화장품학회 2017 대한화장품학회지 Vol.43 No.3

본 연구는 순채 점액질 다당체의 인체 피부와 in vitro에서의 피부 보습효과를 확인하고 화장품 원료로서의 가능성을 평가하기 위한 것이다. 다양한 환경적 스트레스와 노화로부터 피부를 보호하기 위해서는 피부의 수분 보유량을 증가시키고 수분의 손실을 예방해야 한다. 본 연구진은 순채의 점액질로부터 추출한 다당체를 인체 피부에 도포했을 때, 특이적인 윤활성으로 피부에서의 거칠기(roughness)를 개선시켰다는 것을 확인했다. In vitro에서 각질형성세포에 순채 점액질 다당체를 처리했을 때, 피부장벽의 가교 역할을 하는 transglutaminase 1 (TGM1) 유전자의 발현이 증가하였다. 또한 물과 글리세롤의 이동을 조절하는 막관통 단백질 aquaporin 3 (AQP3)와 수분 보유 기질 히알루론산을 합성하는 효소인 hyaluronan synthase 3 (HAS3) 유전자의 발현 또한 증가함을 확인했다. 추가적으로 화장품 원료로서의 가능성을 평가하기 위한 실험에서, 항염증과 콜라겐 합성 촉진 효능을 보였다. 결과적으로 순채의 점액질 다당체는 기존에 없는 새로운 천연 원료로서, 피부에 보습 효과와 항염증, 콜라겐 합성 촉진 효능이 있음을 밝혔다. In this study, we evaluated the skin moisturizing effect of Brasenia schreberi (B. schreberi) mucilage polysaccharide on human skin and in vitro and the potent cosmetic ingredient for skin. To protect skin from various environmental stresses and aging, we should increase moisture content of skin and prevent water loss. We have found that polysaccharides extracted from mucilage of B. schreberi improved the roughness of skin with its lubricating behavior. In vitro, the expression of transglutaminase 1 (TGM1) gene, which plays a role in cross-linking the skin barrier, was increased when the keratinocytes were treated with B. schreberi polysaccharides. In addition, the expression of hyaluronan synthase 3 (HAS3) gene, an enzyme that synthesizes water-binding matrix hyaluronic acid, aquaporin 3 (AQP3), which regulates the movement of water and glycerol were also increased. In addition, an experiment to evaluate its potential as a cosmetic ingredient has shown anti-inflammatory and collagen synthesis-promoting effects. As a result, the mucilaginous polysaccharide from natural products which has not existed before, showed moisturizing effect, anti-inflammation and collagen synthesis-promoting effects for skin protection and hydration.

호염 미생물(Haloarcula vallismortis) 용해물의 자외선유발 피부변화에 대한 효과

김지형 ( Ji Hyung Kim ),신재영 ( Jae Young Shin ),황승진 ( Seung Jin Hwang ),김윤선 ( Yun Sun Kim ),김유미 ( Yoo Mi Kim ),길소연 ( So Yeon Gil ),진무현 ( Mu Hyun Jin ),이상화 ( Sang Hwa Lee ) 대한화장품학회 2015 대한화장품학회지 Vol.41 No.4

피부는 외부 유해물질로부터 내부기관을 보호하는 장벽기능을 하는 대표적인 기관으로 자외선(ultraviolet radiation, UV), 중금속, 각종 산화 물질들과 같은 외부의 위협에 항상 노출되어 있어 손상을 받기 쉽다. 특히 자외선 B (UVB)는 진피의 상부까지 도달하여 화상이나 홍반과 같은 염증반응을 일으키며 멜라닌 생성을 촉진시켜 색소 침착을 유발한다. 지나친 자외선 B의 피부세포로의 유입은 각질세포 및 진피 섬유아 세포의 DNA손상을 야기하고, 세포외기질의 합성을 방해하여 피부탄력감소, 주름생성, 진피 결합조직의 손상과 함께 피부장벽을 붕괴시켜 노화를 일으키며, 장기간 노출 시 심각한 피부 병변으로 이어져 피부세포 사멸 및 종양의 발생으로까지 이어진다. Haloarcula vallismortis는 사해로부터 분리 동정한 미생물로 호염성 고생물의 생장적 특징은 아직 자세히 연구된 바는 없다. 대게 10% 이상의 염도에서 자라는데 실제 생장염도는 평균 20 ∼ 25% 염도에서 자란다. 염도가 높은 호수나 염전에서 주로 발견되기 때문에 강한 햇빛에 대한 방어기작이 존재한다. 그중 하나로 다른 ATP를 생성하기 위한 bacteriorhodopsin외에 halorhodopsin이라는 색소를 이용, 광자(photon)를 흡수하고 염화이온 채널을 개방시켜 생기는 전위차를 이용해 추가로 에너지를 생산한다. 또 carotenoid 색소로 인해 농도가 높을시 분홍색 또는 빨간색을 띄는 특징이 있는데 이것이 강한 자외선에 대한 방어기작을 할 것이라고 여겨진다. 본 연구는 호염성 고세균이 자외선을 에너지 소스로 이용하는 특성을 이용하여 자외선으로부터 피부를 방어하는 방법을 개발하고자 이들의 피부각질세포에서 자외선에 의한 항염 효과 및 DNA 손상 방어 효과를 확인하였다. 그리고 이들을 천연 자외선 차단제의 소재로서 사용할 수 있음을 확인하였다. Skin carrys out protective role against harmful outer environment assaults including ultraviolet radiation, heavy metals and oxides. Especially, ultraviolet-B (UVB) light causes inflammatory reactions in skin such as sun burn and erythma and stimulates melanin pigmentation. Furthermore, the influx of UVB into skin cells causes DNA damage in keratinocytes and dermal fibroblasts, inhibition of extracellular matrix (ECM) synthesis which leads to a decrease in elasticity of skin and wrinkle formation. It also damages dermal connective tissue and disrupts the skin barrier function. Prolonged exposure of human skin to UVB light is well known to trigger severe skin lesions such as cell death and carcinogenesis. Haloarcula vallismortis is a halophilic microorganism isolated from the Dead Sea, Its growth characteristics have not been studied in detail yet. It generally grows at salinity more than 10%, but the actual growth salinity usually ranges between 20 to 25%. Because H. vallismortis is found mainly in saltern or salt lakes, there could exist defense mechanisms against strong sunlight. One of them is generation of additional ATP using halorhodopsin which absorbs photons and produces energy by potential difference formed by opening the chloride ion channel. It often shows a color of pink or red because of their high content of carotenoid pigments and it is considered to act as a defense mechanism against intense UV irradiation. In this study, the anti-inflammatory effect of the halophilic microorganism, H. vallismortis, extract was investigated. It was found that H. vallismortis extract had protective effect on DNA damage induced by UV irradiation. These results suggest that the extract of halophilic bacterium, H. vallismortis could be used as a bio-sunscreen or natural sunscreen which ameliorate the harmful effects of UV light with its anti-inflammatory and DNA protective properties.
