Hermansky-Pudlak syndrome (HPS) is a genetically heterogeneous inherited disease causing hypopigmentation and prolonged bleeding times. An additional serious clinical problem of HPS is the development of lung pathology, which may lead to severe lung disease and premature death. No cure for the disease exists, and previously, no animal model for the HPS ...

A variety of congenital and acquired etiologies can give rise to the radiographic finding of a unilateral hyperlucent lung. An unusual case of congenital lobar emphysema diagnosed in a young adult following the initial discovery of a hyperexpanded, hyperlucent lung is reported. Although subsequent bronchoscopy and radiologic studies detailed extensive ...

Asbestos-induced pleural fibrosis is the most common radiographic abnormality among asbestos-exposed persons. Circumscribed pleural plaques and diffuse pleural thickening account for more than 90% of the asbestos-induced chest wall abnormalities, and their prevalence is expected to increase for the next 15 to 20 years. Several investigators have recently ...

There is evidence that in infants with unilateral lung disease, oxygenation improves when the good lung is uppermost--the reverse of the situation in adults. We performed krypton-81m ventilation scanning in 18 infants and very young children (11 days to 27 months old) with and without abnormal chest radiographs. Scanning was performed ...

99mTc-Technegas scintigraphy is used for evaluation of abnormality of ventilation in pulmonary emphysema. Although the abnormality of ventilation distribution is very easy to find, there is not an objective index. The evaluation is subjective and different by each radiologist. It was also difficult to compare each cases and the clinical course in the same ...
The occurrence and determinants of thickened interlobar fissures were assessed in 147 insulators, in order to test the hypothesis that radiographic abnormalities in minor (FMN) and/or major (FMJ) interlobar fissures are associated with restrictive respiratory impairment, which may reflect early parenchymal lung fibrosis. According to the diagnostic ...
Intravenous augmentation therapy with human plasma alpha 1AT represents the current "state of the art" form of therapy for alpha 1AT deficiency. Augmentation therapy is directed towards specific correction of the central abnormality of alpha 1AT deficiency i.e., to correct the insufficient anti-neutrophil elastase screen of the lung. By augmenting ...

The lungs are generated by branching morphogenesis as a result of reciprocal signalling interactions between the epithelium and mesenchyme during development. Mutations that disrupt formation of either the correct number or shape of epithelial branches affect lung function. This, in turn, can lead to congenital ...
The use of single photon emission computed tomography (SPECT) and radiolabeled aerosols for lung scanning offers theoretical advantages over conventional gamma camera imaging. We verified the feasibility of using such a system to define particle deposition. First, in two dogs, we detected segments of the lung which had received fewer radiolabeled particles ...
Radiation pneumonitis occurs 6 to 12 weeks after thoracic irradiation, and is thought to be due to direct radiation-induced lung injury.

Lysyl oxidases, a family comprising LOX and four LOX-like enzymes, catalyze crosslinking of elastin and collagens. Mouse Lox was recently shown to be crucial for development of the cardiovascular system because null mice died perinatally of aortic aneurysms and cardiovascular dysfunction. We show here that Lox is also essential for development of the respiratory system and the integrity of elastic ...
