A Case of Eales' disease in a 36 years, old R.O.K. officer, male, is presented in this report. This patient has been suffered from Eales' disease for these 3 years. Although the recovery from this disease was occurred two times previously, it was resulted as Complete blindness of O. D. due to the Complications of this disease and poor visual acuity of O. S. on account of marked vitreous opacity and retinal hemorrhage in spite of intensive treatment with anti-tuber culous agents, steroids, varidase and subconjunctival injection of 3% Sodiumchloride solution.

Eradication regimens for Helicobacter pylori infection have some side effects, compliance problems, relapses, and antibiotic resistance. Therefore, alternative anti-H. pylori or supportive antimicrobial agents with fewer disadvantages are necessary for the treatment of H. pylori. We investigated the pH-(5.0, 6.0, 7.0, 8.0, 9.0, and 10.0) and concentration (0.032, 0.064, 0.128, 0.256, 0.514, and 1.024 mg/mL)-dependent antibacterial activity of crude urushiol extract from the sap of the Korean lacquer tree (Rhus vernicifera Stokes) against 3 strains (NCTC11637, 69, and 219) of H. pylori by the agar dilution method. In addition, the serial (before incubation, 3, 6, and 10 min after incubation) morphological effects of urushiol on H. pylori were examined by electron microscopy. All strains survived only within pH 6.0-9.0. The minimal inhibitory concentrations of the extract against strains ranged from 0.064 mg/mL to 0.256 mg/mL. Urushiol caused mainly separation of the membrane, vacuolization, and lysis of H. pylori. Interestingly, these changes were observed within 10 min following incubation with the 1 x minimal inhibitory concentrations of urushiol. The results of this work suggest that urushiol has potential as a rapid therapeutic against H. pylori infection by disrupting the bacterial cell membrane.

Transient transfection assay has been done to evaluate whether the c-jun activation would be prerequisite to the induction of permissiveness against human cytomegalovirus using in vitro cell model in which U937 has been induced to express CD11b and CDl4 to become potential monocyte/macrophage cells by TPA treatment. U937 cells were treated with 10 microM, 50 microM or 100 microM of TPA. The cell morphology change was observed and the expression of the CD11b and CDl4 was confirmed by FACS. Differentiated cells were transfected with pJLuc reporter vector which contained the wild type murine c-jun promoter spanning the SP1, CTF, ATF/CREB and MEF-2 binding sites upstream of the firefly luciferase gene. After 48 hrs of transfection, the cells were infected with HCMV Towne strain and the luciferase activity was assessed at 1 h and 4 h pi. The transfection assay showed no activation of the c-jun promoter at 1 h pi, instead, it showed 2 times increase of the its activity at 4 h pi. There was no difference of the c-jun promoter activation between TPA treated and untreated U937 cells, implying that c-jun activation might not be prerequisite for allowing cells to be premissive to HCMV, although HCMV infection itself could activate c-jun promoter.

OBJECTIVES: The Korean College of Neuropsychopharmacology and the Korean Academy of Schizophrenia developed the Korean medication algorithm project for schizophrenia (KMAP) to aid clinical decisions. The purpose of this study was to investigate problems and revision of Korean Medication Algorithm for Schizophrenia after feasibility test. METHODS: A total of 108 schizophrenia patients were enrolled at 19 centers and treated according to the algorithm. Prescribing investigators were able to change the recommended treatment strategies of the algorithm if necessary. All subjects were assessed over a 4-month period. Appropriateness of choice, dosage, duration and switch of antipsychotics and definition of treatment response were examined. RESULTS: Compliance of 1(st) choice antipsychotics in KMAP was favorable. Atypical antipsychotics which is a 1(st) stage drug selected first was above 84%, especially in case of no previous medical history was nearly all. In case that shift of stage was needed, there is a trend that combination treatment stage (6(th) stage) and clozapine treatment stage (5(th) stage) were preferred to rather than 3(rd) stage and 4(th) stage (typical antipsychotics and atypical antipsychotics treatment stage). The rates of switching antipsychotics at the time points other than CDP (critical decision points) was low and the reason was almost the side effects. So the compliance of CDPs in KMAP was good in case of insufficiency of treatment response. Also the reasons why many investigators continued using current antipsychotics without switching despite insufficiency of treatment response were definition of treatment response, discrepancy between brief symptom rating scale for negative symptom and decision of clinicians. In addition, compliance of co-existence symptoms and side effect of medication in KMAP was favorable. CONCLUSION: It is some difference from clinical practice such as stage of antipsychotics, definition of treatment response and usefulness of brief symptom rating scale for negative symptom. But the majority apart from points of preceding paragraph is feasible in clinical practice. These results are essential to revise the next version of KMAP.

Infectious keratitis is the most common serious ocular infection, and may be caused by various bacteria, fungi, viruses and parasites. The authors performed prospectively an epidemiological study to identify risk factors and causative organisms, and to evaluate clinical manifestations, methods and results of treatment in infectious keratitis under the identical protocol from April 1995 to September 1997. Logistic regression analysis [univariate analysis and multivariate analysis] was used to evaluate possible risk factors. Six hundred sixty cases of infectious keratitis reported from 19 hospitals were studied. Two hundred eighty-three organisms[247 bacteria, 32 fungi, 4 acanthamoeba] were detected in 626 eyes with infectious keratitis excluding 34 pherpetic keratitis. The Pseudomonas aeruginosa, coagulase negative staphylococcus, Staphylococcus aureus and Serratia marcescens were the major orgnisms in bacterial keratitis. Aspergillus, Fusarium and Candida were the major isolates in fungal keratitis. Contact lens wear was a risk factor for bacterial keratitis. Female, age[less than 40 years] and occupation[student, house-wife, office worker, servise] were associated with bacterial keratitis. Risk factors in herpetic keratitis were age[between 40 and 59 years] and ocular adnexal diseases. Male was associated factor with herpetic keratitis.

To identify risk factors and causative organisms, and to evaluate clinical manifestations, methods and results of treatment in infectious keratitis, an epidemiological study was performed prospectively under the identical protocol from April 1995 to March 2000.Logistic regression analysis was used to evaluate possible risk factors. The 1474 cases of infectious keratitis reported from 22 hospitals were studied. Five hundred forty-four organisms(442 bacteria, 82 fungi, 20 A c a n t h a m o e b a)were detected in 1320 eyes with infectious keratitis excluding 154 herpetic keratitis. The Pseudomonas aeruginosa was the most common organism in bacterial keratitis, and Fusariumspp. was the major isolate in fungal keratitis. Contact lens wear and occupation(industry, forester, miner, fisherman)were the risk factors for bacterial keratitis. Risk factors in fungal keratitis were fifth decade of age, farmer, and systemic diseases(diabetes mellitus etc.). Risk factors in herpetic keratitis were male and occupation(office worker, service, student, housewife). Risk factors in Acanthamoeba keratitis was contact lens wear.
