1. Control of respiration in fish, amphibians and reptiles
Fish and amphibians utilise a suction/force pump to ventilate gills or lungs, with the respiratory muscles innervated by cranial nerves, while reptiles have a thoracic, aspiratory pump innervated by spinal nerves. However, fish can recruit a hypobranchial pump for active jaw occlusion during hypoxia, using feeding muscles innervated by anterior spinal nerves

2. Hemorragia alveolar fatal: estudo histológico detalhado de necropsias / Fatal alveolar hemorrhage: detailed histological analysis of necropsies
Alveolar haemorrhage is a syndrome presented by many diseases each one with its particular physiopathologic mechanism resulting in pulmonary bleeding. The detailed histological analysis of these patients can help understanding this syndrome. In this study we reviewed and described histological findings of lung slides and medical records from patients whose c

3. Efeito da solução salina hipertônica nas lesões resultantes da isquemia/reperfusão hepática: estudo experimental em ratos / Effect of hypertonic saline solution during ischemia/reperfusion injury in rat liver
Introduction: During liver ischemia, the drop in mitochondrial energy production leads to cellular damage, which is aggravated during restoration of blood supply. Besides local hepatic injury, the ischemia/reperfusion process can trigger a systemic inflammatory syndrome producing remote organ damage. To control these alterations in clinical conditions like l

4. Pulmonary blood supply in bidirectional cavopulmonary anastomosis with pulsatile pulmonary blood flow: quantitative analysis using radionuclide angiocardiography.
OBJECTIVE: To establish a non-invasive method for quantitative analysis of pulmonary perfusion in patients with bidirectional cavopulmonary anastomosis (BCPA) and sources of pulsatile blood flow. The method should quantify left to right lung flow ratio and relative contribution of BCPA and sources of pulsatile blood flow to perfusion of each lung. DESIGN: A

6. Duplicate sources of pulmonary blood supply in pulmonary atresia with ventricular septal defect.
In pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries, there is a tendency for each collateral artery to be the sole supply to a particular region of lung. On injection into a collateral artery, however, "wash-out" of contrast medium by non-opacified blood from a second source is sometimes seen. Alternatively, contr

7. Extralobar lung sequestration associated with fatal neonatal respiratory distress
The radiological and pathological findings of lung sequestration in a premature infant are described. There was a left-sided variant of the extralobar type with double systemic arterial blood supply, single systemic venous drainage, and an incomplete bronchial tree for the remainder of the left lung.

8. Congenital bronchopulmonary vascular malformations: clinical application of a simple anatomical approach in 25 cases.
Congenital malformations of the bronchopulmonary airway and related arterial blood supply are a complex group of lesions in which abnormalities of venous drainage and lung parenchyma may coexist. Twenty five cases have been analysed, by a method whereby each anatomical component is separately considered. All 25 patients had abnormalities of the tracheobronch

9. Unilateral congenital dysplasia of lung associated with vascular anomalies
Hislop, A., Sanderson, M., and Reid, L. (1973).Thorax, 28, 435-441. Unilateral congenital dysplasia of lung associated with vascular anomalies. In three cases of unilateral lung dysplasia the structural changes have been analysed quantitatively to throw light on the nature of the anomaly and stage of its appearance. In one case the pulmonary artery was hypop

10. Non-invasive assessment of pulmonary blood supply after staged repair of pulmonary atresia.
Radionuclide studies were performed to determine pulmonary blood flow in six children who had undergone surgery for pulmonary atresia, ventricular septal defect, and hypoplastic pulmonary arteries with or without major aortopulmonary collateral arteries. Lung blood flow was assessed from both particle perfusion lung scans and the pulmonary and systemic phase

11. Pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries. Effect of systemic pulmonary anastomosis.
In nine patients with pulmonary atresia, ventricular septal defect, and major aortopulmonary collateral arteries, the effect of a systemic-pulmonary anastomosis on the lung was studied by comparison of pre- and postoperative cine angiograms. Selective injections into the collateral arteries were performed in all patients and the source of blood supply to eac

12. Pathological findings after right lung transplantation in a patient with fibrosing alveolitis
The pathological findings in a patient who died two months after right lung transplantation for fibrosing alveolitis are reported. The cause of death was haemoptysis, due to penetrating ulceration causing a fistula between the surface of the cartilagenous part of the main bronchus of the donor lung and the right upper lobe pulmonary artery. The opening in th
