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.
作者从230份脑脊液样本中得出了巴塞罗那地区儿童谷草转氨酶（AST）、乳酸脱氢酶（LDH）、乳酸脱氢酶同工酶及腺苷脱氨酶（ADA）的参考值。得出的参考值如下：AST：样本数n为208；平均值为6.91U/L，标准差s为±2.71U/L。ADA：样本数n为175；第50百分位数为0.388U/L；第97.5百分位数为1.64U/L；第2.5百分位数为0U/L。LDH：样本数n为148；第50百分位数为9.54U/L；第97.5百分位数为24.96U/L；第2.5百分位数为3.81U/L。LDH同工酶：样本数n为82；LDH-1：平均值为41.31%，标准差s为±5.41%。LDH-2：平均值为30.79%，标准差s为±2.84%。LDH-3：平均值为20.3%，标准差s为±4.11%。LDH-4：平均值为6.02%，标准差s为±2.48%。LDH-5：平均值为2.47%，标准差s为±1.7%。新生儿的AST和LDH活性较高，LDH同工酶的分布也有所不同。ADA未显示出差异。
