We experienced nutiple brain abscess in two neonates. Diagnosis was made CT scan, Which revealed multiple ring-like enhancing leason in both frontoparietal and left posterior parietal cerebral parenchyme. Therapy was consisted of systemic antibiotic treatment and CSF V-P shunt operation due to complicated hydrocephalus. One neonate was died and the other neonate has been followed up due to convulsion and neurological sequale.

The folling results were obtained through the clinical review and Virology Laboratory of 100 cases of meningitis seen at ward of the pediatric department of Has Sung Hospital during the period from May to June, 1993. 1) Early childhood period was the most frequent age group and male was predominant in aseptic meningitis. 2) The common chief complaints were fever, vomiting, headache in order. 3) On physical examination meningeal irritation signs were not prominent. 4) On admission, leukocytosis (WBC count>10.000/mm(3)) on peripheral blood was showed in 36%. 5) The findings of cerebrospinal fluid showed that cells (Mean WBC count 671.8/mm(3)) were increased in all cases, and protein and sugar were mostly within normal limit. 6) Echovirus 9 was thought to be main causative agent according to the cerebrospinal fluid culture and antibody test. 7) On follow up study 2 months after discharge, 14 cases showed minimal abnormalities of EEG but no abnormal finding in BERA.

PURPOSE: As the first-line pharmacotherapy for erectile dysfunction (ED), phosphodiesterase type 5 (PDE5) inhibitors are widely used and their clinical efficacy is well established. But up to now, most of these comparative studies have been based on questionnaires, and Udenafil and Mirodenafil, which have recently been developed in South Korea, have not yet to be compared in clinical studies. We compared and analyzed the efficacy of five PDE5 inhibitors using the sexual stimulated (SS)-Penogram. MATERIALS AND METHODS: A total of 347 patients taking PDE5 inhibitors for the treatment of ED and underwent SS-Penogram was enrolled in this study. AUC (area under the curve) of SS-Penogram was compared in each PDE5 inhibitors. Differences in AUC according to age, combined disorders, serum testostereone and prolactin, cholesterol and IIEF were also analysed using Chi-square and Kruskal-Wallis test. P-value less than 0.05 was considered as statistically insignificant. RESULTS: Ratios of Type I curves in medication groups with normal erection were not statistically different before and after medication. Ratios of the excellent response (>50 % increase in area under the curve) and non-response groups (no increase or even decrease in area under the curve) in each medication group were not statistically different. CONCLUSIONS: In this clinical comparative study of the efficacy of PDE5 inhibitors using the SS-Penogram, there were no definite differences in efficacy among PDE5 inhibitors.

PURPOSE: This study aimed to assess the effect of gas injection and laser photocoagulation for patients with opened macular holes who had previously undergone trans pars plana vitrectomy. METHODS: A retrospective study for 6 patients (6 eyes) who had opened macular holes after vitrectomy were treated by an outpatient method consisting of laser photocoagulation to the foveal pigment epithelium followed by injection of 100% SF6 gas. Visual acuity, anatomic status of the macular hole, and complications were evaluated. RESULTS: The length of period of gas injection and laser photocoagulation was distributed to 1 month to 8months (mean 3.2 months) and follow up period was distributed to 8 months to 25 months (mean 14.3months). Three of six eyes with gas injection and laser photocoagulation achieved anatomic success and two of them achieved visual improvement by more than two lines. Three eyes among four phakic eyes developed nucleosclerosis of the lens and one eye developed transient elevation of intraocular pressure. CONCLUSIONS: The outpatient gas injection and laser photocoagulation appears to be a safe and cost-effective alternative to repeated surgery for opened macular holes after trans pars plana vitrectomy.

Mammalian cell is critically dependent on a continuous supply of oxygen. Even brief periods of oxygen deprivation can result in profound cellular damage. The aim of this study was to examine the possible mechanism of apoptosis in response to hypoxia in MC3T3E1 osteoblasts. MC3T3E1 osteoblasts under hypoxic conditions (2% oxygen) resulted in apoptosis in a time-dependent manner, determined by DNA fragmentation assay and nuclear morphology, stained with fluorescent dye (Hoechst 33258) Pretreatment with Z-VAD-FMK, a pan-caspase inhibitor, or Z-DEVD-CHO, a specific caspase-3 inhibitor, suppressed the DNA ladder in response to hypoxia in a concentration-dependent manner. An increase in caspase-3-like protease (DEVDase) activity was observed during apoptosis, but no caspase-1 activity (YVADase) was detected. To confirm what caspases were involved in apoptosis, western blot analysis was performed using an anti-caspase-3 or 6 antibody. The 17-kDa protein, that corresponds to the active products of caspase-3 and the 20-kDa protein of the active protein of caspase-6 were generated in hypoxia-challenged lysates, in which the full length forms of caspase-3 and 6 were evident. With a time course similar to caspase-3 and 6 activation, hypoxic stress also caused the cleavage of Lamin A, typical of caspase-6 activity. In addition, the hypoxic stress elicited the release of cytochrome c into the cytosol during apoptosis. These findings suggested that the activation of caspases accompanied by a cytochrome c release in response to hypoxia was involved in apoptotic cell death in MC3T3E1 osteoblasts.

BACKGROUND: To investigate the influence of nocturnal ambient light on visual function and ocular fatigue. METHODS: Sixty healthy subjects (30 men and 30 women) aged 19 through 29 years with no history of ocular disease were recruited. All subjects spent 3 consecutive nights in the sleep laboratory. During the first and second nights, the subjects were not exposed to light during sleep, but during the third night, they were exposed to ambient light, measuring 5 or 10 lux at the eye level, which was randomly allocated with 30 subjects each. The visual function and ocular fatigue were assessed at 7 a.m. on the 3rd and 4th mornings, using best-corrected visual acuity, refractive error, conjunctival hyperemia, tear break-up time, maximal blinking interval, ocular surface temperature, and subjective symptoms reported on a questionnaire. RESULTS: Three men and three women subjects failed to complete the study (4 in the 5 lux; 2 from the 10 lux). For the entire 54 subjects, tear break-up time and maximal blinking interval decreased (P = 0.015; 0.010, respectively), and nasal and temporal conjunctival hyperemia increased significantly after sleep under any ambient light (P < 0.001; 0.021, respectively). Eye tiredness and soreness also increased (P = 0.004; 0.024, respectively). After sleep under 5 lux light, only nasal conjunctival hyperemia increased significantly (P = 0.008). After sleep under 10 lux light, nasal and temporal conjunctival hyperemia, eye tiredness, soreness, difficulty in focusing, and ocular discomfort increased significantly (P < 0.05). CONCLUSION: Nocturnal ambient light exposure increases ocular fatigue. Avoiding ambient light during sleep could be recommended to prevent ocular fatigue.

During 2010 and 2012 grape harvest seasons in Gyeonggi-do, Korea, a white stain symptom was observed on the harvested grape fruits in 'Campbell-Early' and 'Kyoho' varieties. In samples collected from the infected vine, two different strains of pathogenic fungi have been found and identified as Acremonium acutatum and Trichothecium roseum based on fungal morphology and nucleotide sequence of internal transcribed spacer (ITS) and supported by the phylogenetic analysis of the rDNA-ITS region. The DNA homologies of the isolated strains were 99.8% and 99.6% identical with T. roseum (IFB-22133) and A. acutatum (CBS682.71), respectively. In the pathogenicity test, the spores of A. acutatum and T. roseum sprayed on the grapes caused white stain symptoms on the fruits in two weeks after the artificial inoculation, which is similar to observations in the field. To our knowledge, this is the first report of white stain symptoms caused by A. acutatum and T. roseum on the grapes in Korea.
