ABSTRACT
Objective To observe the effect of furosemide on stria vascularis cultivated in vitro from guinea pig, to explore the probable mechanism of furosemide ototoxicity.Methods 20 healthy pigmented guinea pigs was randomly divided into two groups Furosemide group (n=16), control group (n=4). The stria vascularis explant were cultured for 24 hours using the explant-culture technique. Experimental groups were added into imediately different final concentration of Furosemide (60ug/ml?300ug/ml?600ug/ml?1250ug/ml?2500ug/ml) differently, and continuously cultivated 30 minutes or 90 minutes , then observed structure feature of the cultivated stria vascularis .Results Furosemide group did not show pathological changes such as edema of stria vascularis,shrinkage of the intermediate cells and enlargement of intercellular spaces. No significant changes were found in the stria vascularis structure features between furosemide group and control group. Conclusion Furosemide did not induce remarkable edema on cultivated stria vascularis from guinea pig.These findings suggested that furosemide might induce ototoxicity by indirect mechanism.
