Capacidad respiratoria, niveles de Vitamina C y Malonilaldehído en estudiantes de bioanálisis fumadores y no fumadores

several authors have shown the implications of smoking in the alteration of respiratory capacity and oxidation / antioxidation system and the importance of screening them for help in preventing various diseases. in the present investigation was to assess respiratory capacity and vitamin c (vc) and malondialdehyde (mda) levels of smokers and non smokers. partici - pated 50 bioanalysis students both sexes, classified by the world health organization in daily smokers (df), occasional smokers (of) and non-smokers (nf). the evaluated parameters were: forced expiratory volume in first second (fev1) and forced vital capacity (fvc), levels of vc and malonilaldehyde. results presented as x ± sd and percentages and statistically analyzed by anova, were 69,2% and 84,6% of students (df, of) had normal values of fvc and fev, respectively, without differences significant height. vc levels (mg/dl) were 1.19 ± 0.30 (nf) with 1.12 ± 0.09 (of) without significant differences between them and the mda (ìm/l) showed a statistically significant increase (p<0.05) their values in of (1.56 ± 0.5) with res pect to nf (0.99 ± 0.60). we conclude that the values of mda showed a significant increase in of, which correspond to manifestations of oxidative stress. however, vitamin c levels, though were lower in fo group, showed no significant differences as well as spirometry
