pubmed-article:3675914 | pubmed:abstractText | Total serum tryptophan concentrations were measured in 74 cataractous patients and 124 controls. No significant differences were observed in the mean values for the cataractous and normal subjects, 11.4 +/- 2.6 and 11.3 +/- 2.2 micrograms/ml respectively, or in the range of values, 7.4-17.1 and 7.3-17.4 micrograms/ml respectively. These results do not support previous reports that serum tryptophan is elevated in cataractous subjects. | lld:pubmed |
