Background : Generally max is higher in treadmill exercise than cycle ergometer exercise. According to Hassen and Wasserman, max with treadmill exercise is higher at ratio of 1.11 than that with cycle ergometer. max also is influenced by race, sociocultural background, exercise habit In this study, max and AT were evaluated between Treadmill and cycle exercise in male Korean college students. Method: Study subjects were 44 male college students. We randomized them into 2 groups; 24 students did treadmill exercise at first and 1 week later did cycle ergometer. Another 20 students did in opposite method. They made symptom limited maximal exercise. Author defined maximal exercise as followings: 1) respiratory exchange ratio(RER)> 1.1, 2) plateau>30 sec, 3) heart rate reserve(HRR) max and AT was /kg/min and /kg/min in treadmill and /kg/min, /kg/min in Cycle Ergometer. The measured-/pred- was in treadmill; in cycle ergometer. Comparing max in treadmill with that obtained by Hassen's method, there were significant differences.(p/pulse, BR, /MVV, between treadmill and cycle but not in , Vd/Vt, Ti/Ttot. At AT there were differences in /pulse, BR, /MVV, Ti/Ttot between treadmill and cycle, otherwise not. Conclusion: According to the result of this study, there are larger gap between treadmill and cycle ergometer in normal Korean adults than foreign data, and it needs further study to obtain reference value of Korea.

Cytomegaloviruses (CMVs) are ubiquitous but highly species-specific agents which commonly infect many animals, including humans. Cytomegalovirus (CMV) pneumonia has been one of the most important opportunistic infections in the immunocompromised host for those who have acquired immunodeficiency syndrome (AIDS) or who have received kidney, bone marrow or other organs. Cytomegalovirus infection has been known to be associated with congenital, infantile and adult nephrotic syndrome. We report a rare case of CMV pneumonia with nephrotic syndrome in a 62-year-old female who recovered fully with ganciclovir.

The first case of allergic bronchopulmonary aspergillosis(ABPA) was reported by Hinson, et al. in 1952. This was followed by a number of significant description of the disorder. Although typical ABP A initially presents with asthma, fleeting pulmonary infiltrates, and marked eosinophilia, there are many other ways in which the disease may be first manifested. Common radiologic findings in ABP A include pulmonary infiltrates, atelectasis, emphysema, fibrosis, lobar shrinkage with hilar elevation, cavitation, pneumothorax, aspergilloma and central bronchiectasis. We experienced a case of allergic bronchopulmonary aspergillosis presenting rare radiologic finding of bilateral pulmonary masses in chest radiography. With oral corticosteroid treatment, the size of both pulmonary masses was decreased significantly and his asthmatic symptoms were improved.
