采用鼻体积测量法对7名年龄20～40岁的健康自愿者(男4,女3)进行试验,研究活动(直至最大费力状态)过程中及活动后休息期鼻粘膜充血的改变与血中乳酸盐、肾上腺素、去甲肾上腺素浓度之关系。其中6名在活动时鼻粘膜收缩,当鼻粘膜收缩达一半时去甲肾上腺素浓度开始上升,而乳酸盐及肾上腺素浓度几乎到最大收缩时才开始上升。活动停止后,鼻粘膜又迅速充血,其程度与肾上腺素及去甲肾上腺素浓度的下降相平行。虽然鼻粘膜再充血到相当的程度,乳酸盐
Nasal volume measurements were performed on seven healthy volunteers aged 20-40 years (male 4 and female 3) to study the changes in nasal mucosal congestion during and after the activity (up to the maximum effort state) Lactate, epinephrine, norepinephrine concentration relationship. Six of them had nasal mucosa contractions during activity, norepinephrine concentration began to rise when nasal mucosa was shrunk to half, and lactate and adrenaline concentrations started to rise almost to maximum contraction. After the cessation of activity, the nasal mucosa is rapidly hyperemic again to a level parallel to the decrease in the concentrations of epinephrine and norepinephrine. Although nasal mucosa reblends to a considerable extent, lactate
