OBJECTIVE: To study the ability of homoharringtonine, 5-fluorouracil and adriamycin on inhibiting the proliferation of rabbit lens epithelial cells (RLEC) and the prevention of after cataract by using homoharringtonine.
METHODS: RLEC were isolated and cultured. (1) The passage RLEC were placed in 24-well tissue culture plates and incubated for 48 hours, then exposed to different concentrations of homoharringtonine, 5-fluorouracil and adriamycin for 24 and 72 hours; (2) The passage RLEC and homoharringtonine, 5-fluorouracil, adriamycin were placed and cultured for 24 hours to investigate the rate of attached cells; (3) The morphological changes of RLEC were studied under light microscope.
RESULTS: The ID50 of homoharringtonine, 5-fluorouracil and adriamycin exposed to RLEC for 24 hours were 0.84 micrograms, 0.58 micrograms and 4.50 ng/ml and those for 72 hours were 0.49 micrograms, 0.33 micrograms and 3.85 ng/ml respectively. In the homoharringtonine group, the rate of attached cells was less than that of 5-fluorouracil and adriamycin groups. The study of the morphological changes showed that the different concentrations of antiproliferative drugs affected on RLEC at different regions.
CONCLUSION: The authors consider that homoharringtonine may be more effective for the prevention of after cataract than 5-fluorouracil and adriamycin.
