Values represented as mean ±SEM. * Significant change in comparison with control at P < 0.05. # Significant change in comparison with gentamicin only treated at P < 0.05. group 1 as control; group 2 received daily GS (100 mg/kg Ip); group 3 received oxygen 2 hr daily for 2 days and then received daily GS; group 4 received oxygen 4 hr daily for 2 days and then received daily GS; group 5 received oxygen 4 hr daily for 4 days and then received daily GS and group 6 received oxygen 2 hr daily for 2 days and then during daily injection GS received 2 hr oxygen before injection
