神经反射机制在上、下呼吸道的相互连系上起重要作用。1870年Kratchmer曾记载当动物鼻粘膜受机械刺激后,将出现呼吸节律改变,后世称之为鼻支气管反射,大多表现为支气管缩窄,阻抗增高,少数表现为扩张,阻抗降低,支气管敏感性的增高与β-肾上腺能受体的部分阻断有关,鼻腔最敏感的反射原区(哮喘区)在下及中鼻甲前端粘膜。为阐明鼻腔机械刺激对哮喘患者支气管阻抗的影响及这一反射的临床和X线特点,作者等用体积描记法观察了189名17～70岁(男67,女122)受检者,包括:健康人12,无肺部病变的血管运动性鼻炎23,鼻息肉11,中隔偏曲7,
Neuroreflective mechanisms play an important role in the interconnection of the upper and lower respiratory tract. In 1870, Kratchmer once reported that when the animal nasal mucosa is mechanically stimulated, the respiratory rhythm changes. Later generations call it the nasal bronchial reflex. Mostly manifest as bronchoconstriction, increased impedance, and a few appear to be dilation, decrease in impedance, bronchial sensitivity Increased partial block with β-adrenergic receptors, nasal most sensitive areas of the original (asthma area) in the inferior and middle turbinate front mucosa. To clarify the effects of nasal mechanical stimulation on the bronchial impedance of asthmatic patients and the clinical and radiographic features of this reflex, the authors examined 189 subjects ranging in age from 17 to 70 (male 67, female 122) using plethysmography, including: Healthy people 12, non-pulmonary lesions of vasomotor rhinitis 23, nasal polyps 11, septum deviation 7,
