The ganglionated plexus of the trachea of mice was studied quantitatively with a histochemical method that stains electively the ganglion nerve cells in whole-mount preparations. The plexus lies exclusively over the muscular part of the trachea, dorsal to the muscle itself, and it varies considerably in pattern and extent between individual animals. In(More)
The nerve plexuses and ganglionic nerve cells of rat trachea were studied quantitatively in whole-mount preparations stained for acetylcholinesterase. Two nerve plexuses were observed overlaying the smooth muscle layer of the membranous part or the rat trachea. On average, 70 ganglia (range 63-78, S.D. = 6) and 549 neurons (range 334-661, S.D. = 125) were(More)
Glial cell line-derived neurotrophic factor (GDNF) is suggested as a specific neurotrophic factor for midbrain dopamine (DA) neurons, but the molecular mechanism underlying the neuroprotective action of GDNF is not well known. In the present study, we have shown that GDNF increased protein kinase CK2 activity in rat substantia nigra (SN) in a dose-dependent(More)
Only limited information relating neurotransmitters to central regulation of the respiratory system exists. L-glutamic acid has been proposed as the primary neurotransmitter in the nucleus of the tractus solitarius (NTS) of cats. To test whether or not glutamic acid has an effect on the respiratory center, we microinjected L-glutamic acid (1 M, 0.1(More)
