A sensitive assay, utilizing high performance liquid chromatography and sulfhydryl (SH) fluorescence labeling, was used for the quantitative determination of reduced glutathione (GSH) and cysteine (CySH) in senile cataractous lens epithelial cells. The capsule-epithelia (CE), obtained following cataract surgery, were soaked in 0.3ml saline at room temperature for 1 hour. Detached epithelial cells and the capsule with attached residual cells were assayed for GSH and CySH. Regression analysis of the relation between epithelial protein content and capsule wet weight was performed to evaluate the amount of contamination of the CE samples with lens cortex. GSH levels in the cataractous lens epithelial cells were 23.0±11.2 (Mean±S.D.) nmol/mg protein (n=15); CySH levels were 0.51±0.50 nmol/mg protein (n=12). No differences in GSH levels were observed between immature and mature cataracts. Thus, GSH levels in the lens epithelial cells did not appear to decrease with the progression of the senile cataracts.
