Summary
The effect of hydrocortisone, prednisolone, estrogen, progesterone and testosteron on the differentiation of the paracervical ganglion of the rat uterus was examined by the formaldehyde induced fluorescence (FIF) method. Prednisolone and hydrocortisone treatment caused about a tenfold increase in the number of small, intensively fluorescent (SIF) cells. The SIF-cells were larger and organized in larger groups than in untreated animals. The SIF-cells were also arranged in a satellite cell position around the ganglion cells, which were non-fluorescent or showed a weak to moderate FIF. The amount of solitary SIF-cells was increased. No effects detectable by the FIF-method were found with certainty after administration of estrogen, progesterone or testosterone.
The effect of glucocorticoids on the differentiation of autonomic ganglia is discussed. It seems probable that the main part of the developing SIF-cells after glucocorticoid treatment develop from undifferentiated neural cells.
