BACKGROUND The effects of amblyopia on the glucose metabolism in the visual cortex in the resting state are evaluated, the asymmetry of glucose metabolism in the ipsilateral and the contralateral occipital lobes was examined by comparing the number of hypometabolic pixels in both occipital lobes, and the correlation between this asymmetry and the results of(More)
To examine the possibility of luteolin as a whitening agent, we measured antioxidant activity using DPPH assay, NBT/XO assay and intracellular ROS scavengning assay and depigmenting activity using tyrosinase assay, alpha-MSH-induced melanin production in B-16 cells. Luteolin showed dose-dependent anti-oxidant activity in DPPH, NBT/XO and intracellular ROS(More)
OBJECTIVE To investigate the clinical features and visual outcome of patients with peripapillary staphyloma. METHODS The medical records of patients diagnosed as having peripapillary staphyloma at Seoul National University Children's Hospital, Seoul, Korea, between January 1, 1991, and December 31, 2003, were reviewed. Visual acuity and associated ocular(More)
PURPOSE To compare the outcomes of unilateral lateral rectus recession between the first operation and second operation for exotropia. METHODS Thirty-two patients who underwent unilateral lateral rectus recession for exotropia of 15 to 20 prism diopters (PD) were investigated. The follow-up period was at least 6 months. We classified 17 patients without a(More)
A 59-year-old woman was referred to our clinic with sudden visual loss in her right eye after she was treated with 40 mg/day of oral prednisolone for 2 weeks under the diagnosis of idiopathic optic neuritis. At that time, computerized tomography (CT) of the brain showed no evidence of optic nerve or brain pathology. However, there was progressive diminution(More)
OBJECTIVE Mesenchymal stromal cells (MSCs) are multipotent progenitor cells in adult tissues. Current challenges for the clinical application of MSCs include donor site morbidity, which underscores the need to identify alternative sources of MSCs. This study aimed to explore potential new sources of multipotent MSCs for use in tissue regeneration and the(More)
OBJECTIVE This study was performed to confirm the effect of transplantation of human umbilical cord blood mesenchymal stem cells (UCB-MSCs) on hearing restoration in a sensorineural hearing loss (SNHL) animal model. MATERIAL AND METHODS UCB was collected from pregnant women after obtaining consent, and mesenchymal stem cells (MSCs) were extracted. We(More)
The aim of this study was to investigate whether acteoside isolated from Clerodendron trichotomum Thunberg may act as a selective inhibitor of phospholipase A(2) in RBL-2H3 cells. Acteoside dose-dependently inhibited 0.5 μM melittin-induced release of [(3)H]arachidonic acid, which was due to the inhibition of cytosolic Ca(2+)-dependent phospholipase A(2)(More)
Employing microfluorometric system and patch clamp technique in rabbit basilar arterial myocytes, regulation mechanisms of vascular excitability were investigated by applying intracellular pH (pHi) changers such as sodium acetate (SA) and NH4Cl. Applications of caffeine produced transient phasic contractions in a reversible manner. These caffeine-induced(More)
