Each medicine used in the study totally has obivious effect on lens sodium-pump. Either on the molecular and cellular level or on the histological and organic level , they all have their distinctive demonstration. 1.Ouabain、Digoxine、DMSO decrease the expression of αsubunit of sodium pump on mRNA level , the cell morphology and ultramicroscopic structure demonstrated destructive effect,it indicates the cause of cataract of the medicines.2.D-thyroxine、Amphotericin B、Vitamin E increase the expression of αsubunit of sodium pump on mRNA level ,from the demonstration of the cell morphology and ultramicroscopic structure ,it indicates the medicines have protective or anti-distructive effect on lens.3.The medicines have isoform-specific action on lens sodium-pump,it indicates exploitting isoform-specific medicine has a promising clinical application.4. Lens sodium-pumps are inhibited probably lead to cataract, so in clinical medication, especially to the cardiovascular doctor, while he is using the sodium-pump inhibitors, he should pay more attention to adjust the dosage and duration of the drug therapy. 5. To creat the animal model of cataract through inhibiting lens sodium-pump, whether it can be a kind of classical method or not, it is worthy of further research.
