Rat mouse, and chick lenses incubated with 3-aminotriazole under long-wave ultraviolet (UV) show reduced accumulation and incorporation of leucine and a loss of glutathione. The effect on leucine incorporation is strikingly enhanced when capsule-epit

Emory mice (EM) are genetically predisposed to late-onset cataract formation. Our early work has shown UV-exposure slightly enhanced the expected 2 SH----SS conversion of normal mouse lenses only in the cortical regions. There was essentially no diff

Brunescent lenses and normal human lenses more than 70 years old exhibit red fluorescence due to a fluorophor with emission maximum at 672 nm under excitation by the 647.1 nm line of krypton ion laser. The properties and mode of occurrence of this fl

Isolated alpha-, beta-, and gamma-crystallins from young rat lenses were incubated in solution for 16 hr with 3-hydroxykynurenine under ultraviolet (366 nm) light. Controls included: incubation without light, without kynurenine, and with 2-mercaptoet

A series of lens pairs (each pair from the same donor) from human eyebank eyes were incubated in a medium containing tracer leucine. One lens of each pair was exposed to long-wave ultraviolet light. The other was shielded. The irradiated lenses accum

Total calcium and total protein contents have been determined in Emory mouse cataracts from 6 to 19 months of age and also in age-matched Cataract-resistant control lenses. The normal lens calcium is about 0.006 micrograms/mg fresh lens weight; in ca

A blue-green fluorophor (496 nm emission/406.7 nm excitation) occurs in the mouse lens; its increase with age is more pronounced in the nucleus than in the cortex. The level of fluorophor and its rate of production are the same for animals reared in

The authors have put quantitation of human lens fluorescence on a rational basis by using the accompanying Raman signal from lens protein as a normalization factor. The intensity ratio, Fluorescence/Raman (F/R), may be used to compare lenses of diffe
