We examined the variation of monocular pattern reversal topographic visually evoked potentials across a 13.6 degrees visual field and measured the parameters of the VEP waveforms in 37 locations across the field. Eighteen right and 20 left normal eyes were tested from 23 subjects. The mean response densities of the VEP decreased with increasing(More)
PURPOSE To investigate the variation of visual evoked potential (VEP) function at different eccentricities of the visual field in esotropic amblyopes and anisometropic amblyopes. METHODS Data from 5 esotropic amblyopic eyes, 6 anisometropic amblyopic eyes, and 45 control eyes were analyzed. A VERIS system was used to generate a stimulus matrix containing(More)
PURPOSE To investigate the variation of visual function in different eccentricities of the visual field in isometropic amblyopes. METHOD The stimulus matrix containing 61 hexagons was generated on a monitor. The diameter of the entire stimulating field was approximately 13.6 deg of arc; the frame rate of the monitor was 67 Hz. Every hexagon of the display(More)
Several epidemiological investigations have suggested an increased incidence of lymphoma, leukemia, and brain tumor in residents living near power transmission lines. However, some observers failed to confirm such a positive correlation. To evaluate the effects of extremely low frequency (ELF) magnetic fields on leukemogenesis, an experimental animal model(More)
PURPOSE To observe the changes in ciliary processes in endoscopic cyclophotocoagulation, and propose the principle for choosing energy of laser and access of operating. METHODS Endoscopic cyclophotocoagulation was performed in the human eyes donated for corneal transplantation through the limber or the pars plana. The coagulated tissue was checked(More)
Glaucoma has long been recognized as a leading cause of irreversible blindness. According to data on the epidemiology of glaucoma, primary angle closure glaucoma (PACG) is a major form of glaucoma in Asia. This is true especially in populations of East Asian and Chinese descent. The characteristics of glaucomatous epidemiology continued changing with the(More)
Immunized spleen lymphocytes were fused with Balb/c mouse myeloma cells to obtain hybridoma cell line 4B-2, which produces monoclonal antibodies (McAb) against bovine growth hormone (bGH). Balb/c mice were injected with 4B-2 cells to produce ascites antibodies. The specific McAb in the ascites (about 10 mg/ml, subclass IgG1) was purified by immunoaffinity(More)
Human growth hormone (hGH) gene has been inserted into the plasmid pLGV1103 to give the recombinant plasmid pLB-9. It has been introduced into the agrobacterium containing plasmid pGV3850. The recombinant Ti plasmid pGL198(hGH) has been obtained by homologous recombination. The monocotyledon Caladium bicolor has been transferred with pGL198 (hGH) with the(More)
