Values are Mean ± S.E.M of 4-6 separate experiments. Each group consist 6-8 neonatal rats.
a p < 0.001 when compared with control
b p < 0.001 when compared with hypoxic group.
Hypoxic rats- Hx, Hypoxic rats glucose treated - Hx+G, Hypoxic rats oxygen treated - Hx+O, Hypoxic rats glucose and oxygen treated - Hx+G+O, Hypoxic rats epinephrine treated - Hx + E, Hypoxic rats glucose, epinephrine and oxygen treated - Hx+G+E+O
