Two weeks after the onset of symptoms she developed a generalized symmetrical reticular eruption of unbroken hexagons characteristic of livedo reticularis that resolved over several weeks as her condition improved. To our knowledge, this is the first reported case of livedo reticularis to occur in a patient with EBV mononucleosis.展开更多

Unit discharges from individual single neuron were recorded extracellularly with glass-microelectrode in Subnucleus Reticularis Dorsalis(SRD). Visceral-intrusive stimulation is done by colorectal distension. Thermal stimulation with different temperature(40°C, 42°C, 44°C, 46°C, 48°C, 50°C, 52°C) and different stimulus area(diameter of circle : 1.0 cm, 1.5 cm, 2.0 cm, 2.5 cm, 3.0 cm, 3.5 cm, 4.0 cm) was applied around RN12 during nociceptive colorectal distension.Results: SRD neurons could be activated by visceral stimulation within noxious range. Under low temperature of stimulus, especially under45°C of pain threshold to ordinary people, visceral nociceptive afferent facilitated thermal stimulus from the body surface. While after thermal stimulation reached a harmful degree, the thermal stimulus will inhibit visceral nociceptive afferent. Moreover, statistics show that the higher the temperature is, the smaller the size of stimulation area is needed, and they correlate with each other negatively.Conclusion: Visceral nociception could be inhibited by somatic thermal stimulation with specific parameter at medulla level. According to our finding, best thermal stimulation temperature is around 48°C and the best size of stimulation area is around 3.14-7.07 cm2(with 2.0-3.0 cm diameter).展开更多
