Using light and transmission electron microscopy, we have performed a histopathological evaluation of the anterior lens capsule, isolated during cataract extraction from an eye revealing a cellophane-like membrane on the lens surface of the pupil area. In addition to light microscopy showing one third of the anterior capsule had partially detached,(More)
In order to clarify the clinical characteristics and effects of acetylcholinesterase inhibitors of patients with generalized myasthenia gravis with antibodies to muscle specific kinase (MuSK), we investigated seven patients with MuSK antibodies and eleven patients without both antibodies of acetylcholine receptor and MuSK. All patients with MuSK antibodies(More)
The aqueous humor supplies the lens with nutrition. Recently, the existence of epidermal growth factor (EGF) and basic fibroblast growth factor (b-FGF) has been confirmed in the human aqueous humor. For this reason, it was thought that the function of these growth factors was related to the physiological condition of the lens epithelial cells (LEC).(More)
The number of people suffering from atopic dermatitis, a recent social problem believed to have arisen from environmental pollution and changes, continues to increase today, and these patients often encounter complications such as cataract and retinal detachment. In this study, I have conducted (1) a comparative study on the rate of cell proliferation(More)
The growth promoting effect of epidermal growth factor (EGF) was studied in cultures of epithelial cells from human normal and cataractous lenses. The growth potential of lens epithelial cells was measured by MTT assay. The concentration of EGF in culture medium were classified into 7 groups (0 ng/ml-10(3) ng/ml). When the concentration of EGF was 1 ng/ml,(More)
The expression of FGFR 1, 2 and 3 but not FGFR 4 was detected in bovine lens epithelial cells. FGFR 1 expression of both the 2-lg and 3-lg forms was detected by a difference in the lengths of the PCR products. Furthermore, mRNA which included or excluded six nucleotides corresponding to two amino acids in the acid box region of FGFR 1 was detected by a(More)
