11. Echocardiographic methods for assessment of coronary artery disease
Abstract : Upright bicycle exercise echocardiography with digital image acquisition in seated position during exercise and in recumbent position before and immediately after exercise was performed in 66 men, one month after an episode of unstable coronary arte1y disease. It was difficult to obtain images of adequate quality during exercise but new or worsening of wall motion abnormalities not seen in recumbent position after exercise were detected at peak-exercise in patients with good image quality.

12. Cerebral mechanisms in cardiovascular control : studies on haemorrhage and effects of sodium
Abstract : This thesis describes experiments investigating the influence of the brain on cardiovascular adaptations to haemorrhage and excess sodium in conscious chronically prepared sheep. A continuous reduction in blood volume eventually activates a reflex that causes a fall in vascular resistance and heart rate and thereby also in arterial blood pressure. READ MORE

14. Pathophysiology of intrauterine asphyxia
Abstract : Background: The premature infant is at increased risk of cerebral white matter damage, oftenreferred to as periventricular leucomalacia, PVL, which is associated with later developmentof cerebral palsy and cognitive impairment. The etiology of PVL remains unclear, but ischemia-reperfusion followed by generation of free radicals and intrauterine infections havebeen suggested to play an important role. READ MORE

15. Hypoxia and auto resuscitation in the neonatal rodent with special reference to the sympatho-adrenal system
Abstract : Preterm infants exhibit irregular breathing with frequent episodes of apnea, which may be associated with cyanosis and bradycardia. Perinatal asphyxia causes a considerable amount of morbidity and mortality that occurs during early life. Studies of mechanisms responsible for perinatal asphyxia are therefore very important.
