Purpose: To assess the changes of retinal function together with recovery progress in a patient with Vogt-Koyanaki-Harada syndrome using a multifocal electroretinogram (mfERG). Methods: The retinal changes of a 32-year-old woman diagnosed with Vogt-Koyanaki-Harada syndrome have been investigated and compared for different times such as before treatment and 3 and 6 months after treatment using a fluorescein angiogram, electroretinogram (ERG) and mfERG. Results: As time passed, the patient`s visual acuity was recovered, the serous retinal detachment in the posterior pole was restored, and the phenomenon of late subretinal leakage disappeared on fluorescein angiogram, while aggregation and atrophy of the retinal pigment epithelium were detected. The early-stage responses of the retina decreased on ERG; however, it has gradually recovered and was determined to be normal after 6 months. Responses measured on the mfERG have increased during the 6 months after surgery compared to the pre-treatment, but there was still a partial lack of response. Conclusions: In this case, the abnormal condition of retinal function existed continuously on the mfERG, even when the serous retinal detachment in the posterior pole was recovered. In this regard, a long-term systematic investigation and subsequent mfERG treatment have been thought to be necessary for patients with this disease.

Purpose: To evaluate stability and effects of photochromic lenses in light-sensitive patients. Methods: Analyzing 65 patients, this research employed a standardized survey, fundus examination, and slit-lamp biomicroscopy to evaluate the changes in photophobia, tears, asthenopia, and the deterioration of outdoor visual acuity after wearing photochromic lenses for one month. Measurement of visual acuity was performed outdoors at noon on a bright day using Dr. Hahn’s standard test chart for 3 m. Results: Photochromic lenses, considerably decreased photophobia, tears, and asthenopia. The “normal” visual acuity of 38 patients was established without photochromic lenses. Re-examination after the lenses had been worn for a specified period of time showed that 29 subjects could discern at least one line higher than their “normal” acuity. Conclusions: Photochromic lenses reduced photophobia and the disabling effect of bright light such that comfort was increased. Not only did the lenses improve vision, they also enhanced the overall quality of vision.

돌단풍 잎의 항산화, 항염, 항당뇨, 항비만 활성을 탐색하고자 강원도 양구에서 자생하고 있는 돌단풍의 잎을 채집하여 에탄올과 증류수로 각각 추출하였다. 항산화 활성은 DPPH 라디칼 소거반응, 총 폴리페놀 함량 및 총 플라보노이드 함량을 측정하여 검정하였다. 돌단풍 잎의 에탄올과 물 추출물의 DPPH 라디칼 소거능 IC50값은 각각 549.86과 62.14 ㎍/mL이었고, 총 폴리페놀 함량은 에탄올 추출물이 307.63 ㎎/g으로 물 추출물의 총 폴리페놀 함량인 86.96 ㎎/g보다 높게 나타났으나 총 플라보노이드 함량은 에탄올과 물 추출물 각각 118.98과 110.16 ㎎/g으로 비슷한 함량을 나타냈다. 항염 활성은 RAW264.7 세포에 LPS와 돌단풍 잎 추출물을 동시에 10 ㎎/mL 처리하여 NO 생성량을 측정하였으나 효과는 없었다. 항당뇨 활성은 α-glucosidase와 α-amylase 저해활성을 측정하였으며, 돌단풍 에탄올과 물 추출물의 α-glucosidase IC50값은 각각 5.62와 425.63 ㎍/mL이었고, α-amylase IC50값은 각각 4,623.87과 10,000 ㎍/mL 이상으로 돌단풍 에탄올 추출물의 항당뇨 활성은 매우 뛰어났다. 항비만 활성 탐색은 pancreatic lipase의 활성저해를 측정하였으며, 그 결과 돌단풍 잎의 에탄올과 물 추출물의 IC50값은 모두 10,000 ㎍/mL 이상으로 항비만 활성은 없는 것으로 나타났다. 이러한 결과 돌단풍 잎 추출물의 항산화, 항당뇨의 기능성활용 가공식품 및 건강기능식품으로의 개발이 기대된다. In this study, the bioactivities of ethanol (EEAR) and water extract (WEAR) from the leaf of Aceriphyllum rossii were investigated. In the anti-oxidative activity, IC50 of DPPH radical scavenging activity was respectively 549.86 and 62.14 ㎍/mL by EEAR and WEAR. Anti-inflammatory activity of EEAR and WEAR has been evaluated on inhibition of lipopolysaccharide (LPS)-induced nitric oxide (NO) release by the macrophage RAW 264.7 cells. EEAR and WEAR inhibited inflammatory by 5.58 and 16.85% in 10 ㎎/mL, respectively. In the anti-diabetic activity, IC50 of α-glucosidase inhibitory activity was 5.62 and 425.63 μg/mL by EEAR and WEAR. IC50 of α-amylase inhibitory activity of EEAR and WEAR was 4,623.87 and over 10,000 ㎍/mL, respectively. In the anti-obesity, all lipase inhibitory activity (IC50) of EEAR and WEAR was up 10,000 ㎍/mL. Finally, EEAR and WEAR exhibited anti-oxidative and anti-diabetic activity. It suggests that Aceriphyllum rossii could be potentially used as a resource of bioactive materials for health functional foods.
