Functional changes after segmental and lobar resections of the lungs at remote periods of observation

Clinico-roentgenological and functional studies were carried out in 78 patients 2--12 years following segmental (42 patients) and lobar (3) pneumonectomies for tuberculosis. An analysis of the data obtained indicated that partial pneumonectomies within the boundaries of 1-5 segments per se fail to produce significant disorders in the ventilatory and gas metabolism function of the lung. 2-12 years after the operation the patients show considerable ventilatory reserves. Significant respiratory disorders are observed only in patients with postoperative complications and pathological changes in the lung, pleura and bronchi conditioned by tuberculosis and non-specific lung pathology.     

Problems of immuno- and mesenchyma-suppressive therapy of inflammatory liver diseases

We have studied maximal oxygen uptake, maximal heart rate, maximal exercise ventilation and the ventilatory response to exercise in 24 male and 14 female Scottish athletes. The values for maximal oxygen uptake are similar to those reported in other international studies. In eight athletes repeat measurements of maximal oxygen uptake 7-11 months after the initial study showed no change from the initial values. The values for the ventilatory response to exercise in our athletes were normal. The relationship is discussed between maximal oxygen uptake and ventilatory responses to exercise, hypoxia and hypercapnia and it is suggested that these may be related to athletic event.
