Response of the infantile rat to stress.

摘要: The adrenal gland of the neonatal rat is responsive to stress. Three-min exposure at 2 days age either heat or electric shock caused a significant increase in plasma corticosterone from resting level approximately 11 27 μig/100 ml following stress and 16 shock. In 9-day-old levels rose normal 6 14 μg/100 13 time required for maximum response was 30 min 2-day-old 60 rat. Corticosterone increased shock; however, only adequate induce concentration gland. obtained, when present, 5 both (Endocrinology 79: 631, 1966)
