Effect of MPG on glucocorticoid-induced cataract formation in developing chick embryo. 1984

H Nishigori, and R Hayashi, and J W Lee, and M Iwatsuru

Cataract in the developing chick embryo can be easily produced by administration of high doses of glucocorticoid and the cataract is preceded by a decreased level of glutathione in the lens (Nishigori et al, Exp Eye Res 36:617, 1983). In an attempt to prevent cataract formation, various natural and synthetic sulfhydryl compounds, glutathione, cysteine, ergothioneine, penicillamine, cysteamine and N-(2-mercaptopropionyl)glycine, were applied to hydrocortisone-treated developing chick embryos. N-(2-mercaptopropionyl)glycine showed the most potent delaying activity against cataract formation and also lessened the decrease of glutathione level in the lens. However, except for cysteamine, the other compounds tested had little or no effect.

D002386	Cataract	Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence).

D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick
D005978	Glutathione	A tripeptide with many roles in cells. It conjugates to drugs to make them more soluble for excretion, is a cofactor for some enzymes, is involved in protein disulfide bond rearrangement and reduces peroxides.

D006854	Hydrocortisone	The main glucocorticoid secreted by the ADRENAL CORTEX. Its synthetic counterpart is used, either as an injection or topically, in the treatment of inflammation, allergy, collagen diseases, asthma, adrenocortical deficiency, shock, and some neoplastic conditions.
