抄録: The adrenergic innervation of the mesenteric arteries in Wistar- Kyoto rats, spontaneously hypertensive rats (SHR) and rats neonatally treated with monosodium glutamate (MSG rats) was examined by using glyoxylic acid fluorescence histochemistry with quantitative analysis, by assaying tissue catecholamines with high performance liquid chromatography, and partly by electron microscopy. In the mesenteric arteries of SHR, fluorescence histochemistry study revealed that the plexus density of fluorescent nerve fibers was significantly higher, and tissue norepinephrine was increased as compared to control WKY. On the contrary, in the mesenteric arteries of MSG rats, the plexus density was reduced, through no significant difference was observed in catecholamine contents. Electron microscopic examination revealed that many axon bundles were adjacent to the external elastic lamina, and that occasionally the basement membranes of axon and smooth muscle cell were fused together for an at least 130 nm neuromuscular distance. The present study suggests that the adrenergic nerves of the mesenteric artery of SHR have an increase in activity and that those of MSG rats may be accompanied by a reduction in the sympathetic nerve activity.
