Body weight and survival rate of premature rats exposed to oxygen at different concentrations (21, 40, 60 or 95%) with or without exposure to CGRP8–37. a Changes in the body weight of premature rats exposed to 21, 40, 60 or 95% oxygen for 3, 7 and 14 days. b Changes in the survival rate of premature rats exposed to 21, 40, 60 or 95% oxygen for 3, 7 and 14 days. *p < 0.05 vs. 21% group; p < 0.05 vs. 40% or 60% group. c Changes in the body weight of premature rats exposed to 21 or 95% oxygen with injection of CGRP8–37 or normal saline (NS). d Changes in the survival rate of premature rats exposed to 21 or 95% oxygen, with injection of CGRP8–37 or normal saline (NS). *p < 0.05 vs. 21% group; p < 0.05 vs. 95% or 95% + NS group
