Abstract
Sixty-nine early morning urine samples obtained from three groups of young adult males (autistic, mentally handicapped, and a group of men of normal intelligence) were analyzed using the methods described by Trygstad et al. (1980). No consistent patterns of urinary chromatographic profiles were identified. A number of possible contributing factors are discussed in relation to this failure to replicate the results of previous studies.
