[Structure and functional changes in the gastric intramural nervous plexus in emotionally stressed rats exposed to low doses of long-term ionizing irradiation and lead].
Changes in the catecholamine content in adrenergic fibres, acetylcholinesterase activity, and in the energy metabolism enzymes lactate dehydrogenase and succinate dehydrogenase in neurons of the gastric intramural plexus during emotional stress in rats a day after combined exposure to prolonged (30 days) ionizing radiation in a total dose 1.0 Gy and 0.6 mg/kg lead were studied. A decrease in catecholamines in adrenergic fibres and acetylcholinesterase and lactate dehydrogenase activity in neurons was observed. An enhanced sensitivity of the gastric intramural plexus after the prolonged exposure to small doses of ionizing radiation and lead in conditions of emotional stress was suggested.
