Comparison of pathological findings between the groups. Pathological score: Grade 0 –normal, grade 1 –minimal changes only (weak and focal), grade 2 - < 25% of the cortex underwent histopathological changes, grade 3–25–50%, grade 4–50–75%, and grade 5 - > 75%. Group 1 received no treatment except for gentamicin. Group 2 received 100% oxygen therapy + gentamicin. Group 3 received hyperbaric oxygen treatment + gentamicin
