Fig. 2.
Microscopic images of phalloidin labeled inner hair cell and outer hair cell. All examples are from comparable basal, middle and apical regions of explants. (A-C) depict basal, middle and apical region of explants of untreated group. (D-F) depict basal, middle and apical region of gentamicin (GM; 0.3 mM) treated group. (G-I) depict basal, middle and apical region of 1 µg subfraction of SPL extract and GM treated group. (J-L) depict basal, middle and apical region of 5 µg SPL extract and GM treated group. (M-O) depict basal, middle and apical region of 10 µg SPL extract and GM treated group. GM, gentamicin; PL, Piper longum L.; SPL, subfraction of PL.
