Fig 3. Low power transmission electron micrograph of the SGCs taken from the cochleae of the animals treated with kanamycin and furosemide.

Fig 3

A: The SGCs in the cochlea from the control group. The SGCs were arranged tightly. B: The SGCs in the experimental group 1 day following the end of drug administration. Compared with the control group, no reduction in SGC number occurred. C: The 5th-day experimental group. Also no significant reduction in SGC number occurred. D: The 15th-day experimental group. Compared with the control group, a significant reduction in SGC number appeared. E: The 30th-day experimental group. SGC loss was progressive. F: The 60th-day experimental group. SGC loss was further aggravated. Black arrow: spiral ganglion cells; white arrow: myelinated nerve fibers. Scale bar = 50μm.
