Abstract

Extirpation of the cervical sympathetic ganglia (CSG) results in retardation of the growth of young rats (EAYRS and TAYLOR, 1951; LEPEKHINA, 1975). Our purpose was to show the hypothalamic nuclei (supraoptic — SO, paraventricular — PV, suprachiasmatic — SCH, ventromedial — VM, dorsomedial — DM, arcuate — ARC) in which morphologic changes occur after extirpation of CSG in young rats, and to show how these changes are correlated with growth retardation. Twenty intact and twenty-six operated animals were studied during the course of 5 months of postnatal ontogenesis. A karyo- and cytometric study was made on the 10th, 20th, and 30th days after birth as well as at the ages of 2, 3, and 5 months. The results were treated statistically on the computer. Bilateral extirpation of the CSG was made within the first 5 days after birth.
