[Age-related development of calbindin-immunopositive neurons of rat sympathetic ganglia]

Neurons of cranial cervical, stellate and celiac sympathetic ganglia containing calbindin (CALB) were studied in rats (n = 60) aged 3-90 days using immunohistochemical method. The results obtained indicate that the largest population of CALB-immunopositive neurons was located in the stellate ganglion. The proportion of CALB-containing neurons in sympathetic para- and prevertebral ganglia decreased during the development. Final formation of CALB-immunopositive group of neurons was observed by the end of the first month of life.
