title: [Reference values of A.S.T., L.D.H., isoenzymes of L.D.H. and A.D.A. in cerebrospinal fluid of children (author's transl)].
abstract: From 230 C.S.F., authors found the reference values of A.S.T., L.D.H., isoenzymes of L.D.H. and A.D.A. in children from the area of Barcelona. The reference values obtained were: A.S.T.: n, 208; mean, 6.91 U/l., and s, +/- 2.71 U/l. A.D.A.: n, 175; percentil 50, 0.388 U/l.; percentil 97.5, 1.64 U/l., and percentil 2.5, 0 U/l. L.D.H.: n, 148; percentil 50, 9.54 U/l.; percentil 97.5, 24.96 U/l., and percentil 2.5, 3.81 U/l. Isoenzymes of L.D.H.: n, 82; L.D.H.-1: mean, 41.31 per cent and s, +/- 5.41 per cent. L.D.H.-2: mean, 30.79 per cent, and s, +/- 2.84 per cent. L.D.H.-3: mean, 20.3 per cent, and s, +/- 4.11 per cent. L.D.H.-4: mean, 6.02 per cent, and s, +/- 2.48 per cent. L.D.H.-5: mean, 2.47 per cent, and s, +/- 1.7 per cent. Higher activities of A.S.T. and L.D.H. were found in newborns, also varying the distribution of isoenzymes of L.D.H. The A.D.A didn't show variations.
