We report here the records of 10 consecutive Korean patients (10 eyes) with ocular toxoplasmosis which showed the typical clinical manifestations with seropositivity for Toxoplasma gondii specific IgG antibodies by micro-ELISA between 2006 and 2010. Nine patients were males and 1 was female; their age was $50.5{\pm}13.8$ years. The most common accompanying signs were vitritis (100%), anterior uveitis (70%), and scattered white deposit (80%). Pre-existing retinochoroidal scar was found in 1 (10%) patient. All patients received antiparasitic chemotherapy and systemic corticosteroid treatment, which resolved the presenting attack and recovered the visual acuity better than initial one in 9 patients and worse in 1. Optic atrophy, cataract, and retinal neovascularization were observed during the follow-up period and recurrence was detected in 3 eyes (30%) 6 to 20 months after the initial attack. In Korea, although rarely detected and reported, ocular toxoplasmosis needs more attention in clinical field of retinal diseases.

Aldose reductase(AR), a rate-limiting enzyme in the polyol pathway, has been demonstrated to cause the intracellular accumulation of sorbitol or galactitol and hence to play key roles not only in the cataract formation in the lens but also in the pathogenesis of diabetic complications such as neuropathy, retinopathy and nephropathy, etc. In a series of investigations to evaluate potential AR inhibitors from medicinal plants, we have shown that some hot water extracts exhibited a significant inhibition of a significant inhibition of bovine lens AR in vitro. Among active plants, the roots of Angelica dahuria (Umbelliferae) were shown to have relatively potent AR inhibitory activity. Systematic fractionation of the ether soluble fraction monitored by bioassay led to isolation of two furanocoumarins, byakangelicin(I) and ter-O-methyl byakangelicin( II), were identified as potential AR inhibitors, their $IC_{50}$ values being 6.2 M and 2.8 M, respectively.

Specific inhibitors of a calcium activated neutral protease calpain could be used for the treatment of neurodegenerative diseases, cataract and muscular dystrophy diseases because of their therapeutic effects. In the course of screening for potential calpain inhibitors from microorganisms, a new analogue of chymostatins named calmostinol was isolated from the culture filtrate of an actinomycete. The MW was determined to be 596 [(M + H)$\^$+/] by FAB-MS in glycerol matrix. The structure was elucidated to be N-[((S)-1-carboxy-2-phenylethyl)-carbamoyl]-${\alpha}$-[2- iminohexahydro-4(S)-pyrimidyl]-L-glycyl- L-valyl-phenylalaninol, by the spectroscopic methods such as NMR and MS fragmentation studies. Calmostinol exhibited strong activity against calpain while not against a Ca$\^$2+/ -independent cysteine protease papain.

An 18-month-old, female American Cocker Spaniel was presented with a cataract of left eye. The left eye was blind, and anterior uveitis was noted on ocular examination. Ultrasonography of the eye revealed a hyperechoic mass with distinct borders in the vitreous indicative of lens fiber or mass lesion extending from ciliary body. The eye was enucleated after ultrasonographic examination. On gross examination, rupture of posterior capsule was noted adjacent to the ciliary body.

A 1q21.1 microdeletion is an extremely rare chromosomal abnormality that results in phenotypic diversity and incomplete penetrance. Patients with a 1q21.1 microdeletion exhibit neurological-psychiatric problems, microcephaly, epilepsy, facial dysmorphism, cataract, and thrombocytopenia absent radius syndrome. We reported a neonate with confirmed intrauterine growth restriction (IUGR), micrognathia, glossoptosis, upper airway obstruction, facial dysmorphism, and eye abnormality at birth as well as developmental delay at the age of 1 year. These clinical manifestations, except for the IUGR and upper airway obstruction, in the neonate indicated a 1q21.1 microdeletion. Here, we report a rare case of a 1q21.1 microdeletion obtained via paternal inheritance in a newborn with upper airway obstruction caused by glossoptosis and tracheal stenosis.

Purpose: This study was conducted to examine the degree of senile macular degeneration in elders aged 65 or older and identify factors associated with senile macular degeneration in elders within communities. Methods: Participants in this cross-sectional descriptive study were 388 elders without cataract, glaucoma, and diabetic retinopathy. Data were collected through face to face interviews using a questionnaire in an urban area from June 2010 to December 2011. To detect senile macular degeneration, the participants' self-tests were carried out with Amsler grid testing. Stepwise multivariate logistic regression was performed to evaluate the effects of health behavior and knowledge about eye health on senile macular degeneration. Results: The proportion of participants with senile macular degeneration was 11.6%. Factors that significantly increased the risk of senile macular degeneration included eye discomfort and history of ophthalmic examination (p<.05). Factors that significantly decreased the risk of senile macular degeneration included regular change of magnifiers, non-use of magnifiers, and knowledge about preventive effects of non-smoking and antioxidant vitamin intake on senile macular degeneration (p<.05). Conclusion: This study showed that programs for preventing senile macular degeneration were necessary for elders within communities and the results of this study can be used for developing those programs.

본 논문에서는 기존의 백내장 추출 방법을 개선하기 위해 FCM(Fuzzy C_Means) 알고리즘을 적용하여 백내장을 추출하고 분석하는 방법을 제안한다. 제안된 방법은 애견 안구 영상에서 ROI 영역을 추출한다. 추출된 ROI 영역에서 Fuzzy Stretching 기법을 적용하여 픽셀의 상한 값과 하한 값을 조정한다. 퍼지 스트레칭 기법이 적용된 ROI 영역에 Max-Min 기반 평균 이진화 기법을 적용하여 ROI 영역을 이진화한다. 그리고 퍼지 스트레칭 기법이 적용된 ROI 영역에 FCM 알고리즘을 적용하여 양자화한 후에 양자화된 ROI 영역에서 밝기 평균 이진화 기법을 적용하여 이진화한다. 따라서 Max-Min 기반 이진화 기법을 적용하여 이진화된 ROI 영역과 밝기 평균 이진화 기법을 적용하여 이진화된 ROI 영역을 AND 연산을 적용하여 백내장의 후보 영역을 추출한다. 추출된 백내장의 후보 영역에서 침식, 팽창 기법을 적용하여 ROI 영역의 픽셀 크기를 확대 또는 축소하고 타원 형태를 가진 객체 중에서 ROI의 전체 영역의 크기가 1/5보다 적은 객체를 잡음으로 간주하여 제거한다. 잡음이 제거된 백내장의 후보 영역에서 크기가 3/5이상인 영역을 백내장 영역으로 추출한다. 제안된 방법의 성능을 분석하기 위하여 기존의 백내장 추출 방법과 제안된 백내장 추출 방법을 15개의 백내장 영상을 대상으로 실험한 결과, 제안된 방법이 기존의 백내장 추출 방법보다 백내장 추출률이 개선된 것을 확인하였다.

Purpose: The purpose of this study was to identify nursing demands according to general characteristics and diseases of inpatients to whom comprehensive payment systems apply. Methods: This study was designed as a retrospective research study using the electronic medical records of Hospital Information Systems (HIS). Participants were 836 subjects who received seven Diagnostic-Related Group diagnoses among inpatients of one tertiary hospital from January 1, 2015 to June 30, 2015. Data were analyzed using SPSS 23.0. Results: Nursing demand among inpatients'seven Diagnostic-Related Group diagnoses was relatively higher for appendectomy, cataract surgery, and hysterectomy, while there was a significant difference depending on the age, duration of admission, admission path, hospital entry method and Diagnostic-Related Group. Conclusion: The results can be utilized as basic data on accurate nursing demands that reflect various features of patients.
