The aim of this study was to investigate of the relationships between laterality and antioxidants in the patients with bronchial asthma. For this study permission was taken from etic comitee. In 60 facts, which are 30 patients who has bronchial asthma and 30 healthy individuals, the levels of superoxide dismutase, glutathione peroxidase in erytrocyte and serum melatonin have been determined. Morever, modifiye form of Geschwind Score, of handedness questionnaire has been applied for each fact. Right handedness is dominant in bronchial asthmatic patients, the levels of superoxide dismutase in erytrocyte, serum melatonin has been found meaningfully low according to control group. However, the levels of glutathione peroxidase in erytrocyte is low in bronchial asthmatic patients, no meaningful difference between two groups has been determined. A negative corelation has been observed between lateralite and the level of superoxide dismutase. In our study, the result, that there was no relationship between bronchial asthma and left handedness but antioxidant defence system was weakened asthmatic patients.
