Neurology India. 2003 Jun; 51(2): 220-2http://imsear.searo.who.int/handle/123456789/120949Plasma levels of vitamins A, E and C were analyzed in 102 patients with different types of brain tumors. A follow-up study was done with 27 postoperative patients. On comparison with plasma from normal individuals, vitamin A and E were decreased, but the decrease was statistically insignificant. Vitamin C levels remained in the normal range. In a comparative study of preoperative and postoperative cases, plasma vitamin A levels in postoperative glioma patients were significantly higher than those in the pre-operative state. There was no significant difference in the plasma level of vitamins C and E. The results of the present study suggest that the plasma antioxidant vitamins are not altered effectively in brain tumor cases.engAdultAgedAged, 80 and overAscorbic Acid --bloodBrain Neoplasms --bloodCase-Control StudiesHumansMiddle AgedPostoperative PeriodVitamin A --bloodVitamin E --bloodJournal Article
