Abstract:
The ultrastructural changes in growth hormone (GH) cells of rabbit adeno-hypophysis are determined quantitatively with stereological method after burn injury. Blood sugar levels are concurrently measured. The results show: the volume fraction of Golgi complex, mitochondria and rough endoplasmic reticulum shows a 2-phase curve after burn, and it may be divided into 3-periods stress, modulation and functional activation and recovery; the rate of maturation of secretory granules is increased; a close relation between the blood sugar and some activities of GH cell secretion after burn presents; the autocrine shows a negative feedback to the exocytosis in the control group,and a positive feedback in burned ones; the newly formed mitochondria may be originated from the new Golgi complex from the reutilization of plasma components.
