[Nitric oxide-positive structures in the human lung].
Localization and activity of NADPH-diaphorase was studied in lungs from foetuses in the first and the second halves of intrauterine development and from people aged 40-50 years. Bronchial epithelium, vascular endothelium and small peribronchial nerves showed positive enzyme reaction. The highest NADPH-diaphorase activity was demonstrated in bronchial epithelium of foetuses at 35-37th weeks. In mature human subjects bronchi of the same diameter display different enzymatic activity.
