| Research Abstract |
We examined changes in the hypothalamic-pituitary-adrenal(HPA) axis in a mouse restraint stress model of psychological abuse and in autopsy cases to determine a possible indicator for the diagnosis of child abuse. Both results of animal experiments and autopsy samples indicate that stress including abuse for relatively short periods causes adrenal hypertrophy due to the overproduction of glucocorticoids, decrease of adrenal cholesterol which is material for glucocorticoids, and increase of adrenal gene expression of SR-BI, HMGR and HSL that are related to cholesterol supply to the glands. Our results suggest that the analysis of the HPA axis may be useful for the diagnosis of child abuse and determining the duration.
