The freely diffusible radical, nitric oxide (NO), has been assumed to act as a retrograde signaling molecule that modulates transmitter release. Acetylcholine (ACh) is known to function as a typical neurotransmitter. In the present work we have examined the presence of both transmitters (NO and ACh) and their possible relations in the rabbit spinal cord. In(More)
New facts about control of nuclear milieu were recently described. Because calcium is known as an important cellular regulator we designed this study to describe temporal calcium kinetics in neuronal nuclei in canine neocortex after ischemia-reperfusion injury. Seven-minute global cerebral ischemia was followed by reperfusion phase lasting from 0 to 24(More)
A new model of transient global cerebral ischemia in dogs with minimal measures of intervention is described together with a simple scale for evaluation of functional outcome. During pentobarbital anesthesia, a global cerebral ischemia lasting seven minutes was induced by a four-vessel occlusion and a controlled systemic hypotension. The reperfusion phase(More)
Present study is designed to examine an effect of Stobadine, a new cell-protective agent with antiarrhythmic properties, on survival, electron microscopic changes in microvasculatory bed of selected brain areas and acid-base parameters of arterial blood after global brain ischemia and reperfusion. Forty dogs (weighting 6 to 15 kg) were anesthetized using(More)
Adult Respiratory Distress Syndrome results from a variety of different initial insults, including trauma, sepsis, pneumonia and aspiration, and represents a severe form of acute lung injury. The lung samples of a 20-year-old man who had suffered a serious motorbike accident were obtained for histological examination. He died on the seventh day as a(More)
