【Abstract】 Objectives:The lens metabolism and physiology changes in autoimmune cataract of rabbits were studied. Methods:Ten rabbits (20 eyes) received isologous lens protein antigens (IL Ags) in complete Freund’s adjuvant(two times) and incomplete Freund’s adjuvant(two times), and then were divided into group A(Autoimmune Cataract, AIC formed) and group B(non AIC formed). Another 5 rabbits (10 eyes) were served as the control group (group C). Physiological functions and enzyme activities of lenses were observed. Results:Following the AIC formation, the activity of Na + K + ATP ase in lenses of group A was declined, supported by the statistical significance in lens enzyme activity changes between group A and B, group A and C. However, there was no statistical significance between group B and C. Conclusions:There was a close relationship between the AIC formation and lens metabolism changes of rabbits. Therefore, we would assume that the changes of enzyme metabolism in lenses induced by IL Ags is the pathological foundation of AIC.更多还原
