title: Development of the NADPH-diaphorase-positive neurons in the sympathetic ganglia.
abstract: Changes in the distribution of NADPH-diaphorase (NADPH-d) were studied in neurons of the superior cervical ganglion (SCG), stellate ganglion (SG) and celiac ganglia (CG) in newborn, 10-, 20-day-old, 1-month-old, 2-month-old and 6-month-old rats, mice and kittens. NADPH-d-positive neurons were revealed in all sympathetic ganglia in kittens but not in rodents from birth onwards. In kittens, the largest population of NADPH-d-positive cells was found in the SG, the smallest in the SCG (<1%) and we observed only a few cells in the CG. The proportion of NADPH-d-positive cells in the SG increased from 3.1 +/- 0.15% in newborn kittens to 9.3 +/- 0.63% in 20-day-old animals and decreased further from 8.1 +/- 0.75% in 30-day-old kittens to 3.4 +/- 0.54% in 2-month-old animals. The content of NADPH-d-positive cells in the CG and SCG did not change during development. There were no differences in cross-sectional area between neurons located in different ganglia of animals from the same age group under study. We conclude that the development of NADPH-d-positive neurons in different sympathetic ganglia has its own time dynamics and is completed by the end of the second month of life.
