Clostridium perfringens is an anaerobe responsible for a wide range of diseases in animals and humans. Symptoms associated with C. perfringens food poisoning are caused by enterotoxin expressed only during sporulation of C. perfringens. It has been known that only 6% of global C. perfringens isolates carry the enterotoxin gene. We found 2 strains of enterotoxigenic C. perfringens out of 33 strains isolated from various sources in Korea using PCR. It was also found that these two strains were both type A that were strongly associated with food poisoning by checking the presence of four major lethal toxins (a-, B-, e-, l-toxin) using PCR. These results suggest that foodborne illness caused by C. perfringens may be common in Korea and that public education is necessary to prevent contamination of foods by this organism.

Lymphoma of the prostate is exceedingly rare. Much more common than primary lymphoma of the prostate id secondary involvement of malignant lymphomas originating at other sites. A variety of treatments have bee n used, including prostatectomy, radiotherapy or combinations of chemotherapy and radiotherapy. Generally, the prognosis is very poor, and there is currently no consensus regarding treatment. We report on a patient with T-cell lymphoma who presented with symptoms of bladder neck obstruction. The patient has been asymptomatic and under complete remission after completion of doxorubicin-based chemotherapy for 2 cycles.

PURPOSE: Although the process by which intravitreal perfluorocarbon gas is absorbed is incompletely understood, it is known that considerable absorption of intravitreal perfluorocarbon gas occurs through the aqueous humor. The aim of the study was to evaluate experimentally the effect of topical aqueous humor suppressants on the intravitreal perfluorocarbon gas bubble duration. METHODS: After sulfur hexafluoride and perfluoropropane were injected intravitreally in ten rabbits, we measured the time of gas bubble disappearance in eyes treated with topical aqueous humor suppressants and in those not treated. RESULTS: The mean time(+/-SD) to disappearance of 0.4 cc of sulfur hexafluoride was 6.0+/-0.71 days, which was prolonged to 8.0+/-0.71 days with topical aqueous humor suppressants. The mean time(+/-SD) to disappearance of 0.2 cc perfluoropropane was 14.8+/-0.84 days, while it was prolonged to 22.0+/-1.58 days with topical aqueous humor suppressants. CONCLUSIONS: Sulfur hexafluoride and perfluoropropane intravitreal gas bubbles last longer in rabbit eyes treated with aqueous humor suppressants than in fellow control eyes.

When illuminated by blue light, the human crystalline lens exhibits green autofluorescence. Autofluorescence of the human lens were analyzed quantitatively in vivo as a function of age in 75 healthy individuals{150 eyes) without cataract, ranging in age from 17 to 63 years. Lenses were scanned through the dilated pupil along the optical axis, generating a fluorescence profile consisting of anterior and posterior peaks of lens, using an automated scanning fluorophotometer(Fluorotron master) coupled with a lens system designed for high resolution of the anterior segment structures. Anterior peak autofluorescence increased linearly by 90 ng fluorescein/ml per decade and posterior peak autofluorescence by 70 ng fluorescein/ml per decade. No significant difference between right and left eyes was demonstrated for anterior or posterior peak autofluorescence. We suggest that the quantitative analysis of the autofluorescence of the human lens might be useful to investigate the changes of the aging lens proteins and the pathogenesis of cataract.

8.Histopathologic Findings of an Unsuccessful Molteno Implant.
Journal of the Korean Ophthalmological Society 1999;40(7):1944-1949
We documented the histopathologic findings of an eye with Molteno implant that was nonfunctional at 3 years after implantation.In 1995,a 62-year-old woman developed neovascular glaucoma in her right eye,and installation of a Molteno implant was performed.However,she was lost to follow-up until 1998,when she presented with a blind eye that have to be enucleated with molteno implant because of painful phthisis bulbi.On external examination the implant plate was located in the superotemporal equatorial region of the globe,8 mmposterior to the limbus and 9 mm anterior to the optic nerve.There were adhesions between the plate and surround-ing fibrous tissue.The drainage tube into the anterior chamber left in situ. On microscopic examination the adjacent bleb wall consisted of multilayer, degenerated collagenous connective tissue,maximal 0.7 mmin thickness.Its inner portion mainly consisted of paucicellular,hyalinized and sclerotic col-lagen fibers and outer portion was relatively fibrovascular tissues with a few vascular endothelial cells and fibroblasts.And,there were chronic lym-phocytic infiltrates around a silicone tube insertion site into the anterior chamber.

OBJECTIVES: The objective of this study was to identify the factors associated with suicidal ideation among the elderly living alone received the elderly care service in a rural area. METHODS: This study was surveyed 206 the elderly living alone who received the elderly care service in G-gun, Jeollanamdo. The collected data were socio-demographic and health-related characteristics, family support and suicidal ideation. The used methods for statistical analysis were used t-test, analysis of variance, Pearson's correlational analysis and the multiple logistic regression analysis. RESULTS: In univariate analysis, the suicidal ideation of the elderly living alone was statistically significant associated with age, monthly income, sufficiency of sleeping, depression, stress, activities of daily living, instrumental activities of daily living, perceived health status and family support. As a result of multiple regression analysis, the associated factors with suicidal ideation were age, depression, stress and the activities of daily living. CONCLUSIONS: The suicidal ideation of the elderly living alone in the rural area was associated with age, mental health and independency of living. It will be needed the multidisciplinary approaches to prevent the suicidal ideation and attempts of the elderly living alone.
