Increased lens dipeptidase activity in aging and cataract

Increase in lens gangliosides due to aging and cataract progression in human senile cataract.

Gangliosides were isolated from human senile cataractous lenses by solvent extraction, DEAE-Sephadex column chromatography, and thin-layer chromatography. The content and composition of gangliosides were examined in individual lens tissues. Three predominant gangliosides, GM3, GM1, and GD1a, were tentatively identified in comparison with authentic brain gangliosides, and several unidentified ga...

Treatment of ophidism-induced bilateral canine cataract by extracapsular lens extraction and intraocular lens implantation

The aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. A 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. The dog was bitten by a snake nearly 4 months ago. A 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. In the left eye, posterior synechia was detected in the ...

Germ-line and somatic EPHA2 coding variants in lens aging and cataract

Rare germ-line mutations in the coding regions of the human EPHA2 gene (EPHA2) have been associated with inherited forms of pediatric cataract, whereas, frequent, non-coding, single nucleotide variants (SNVs) have been associated with age-related cataract. Here we sought to determine if germ-line EPHA2 coding SNVs were associated with age-related cataract in a case-control DNA panel (> 50 years...

Antibodies to lens antigens in cataract and after cataract surgery.

By means of an enzyme-linked immunosorbent assay (ELISA) antibodies to whole lens homogenate were found in 50.0% of 38 patients with senile cataract and in 57.3% of 75 controls. The antibody titres were in the range of 10-160 in both groups. IgG antibodies occurred in 44.7% of patients and in 45.3% of controls, whereas IgM antibodies were found in 21.1% of the patients and in 40.0% of the contr...
