S-Methylcysteine has been isolated from the nonprotein nitrogen fractions of cabbage, turnips, and several other crucifers, and the structure of the amino acid was established by chemical studies and by comparison with a synthetic material (14). Subsequently, this compound has been found in garlic and onion (5)) kidney bean seeds (6)) Neurospora crassa (7)) and the hemolymph of Prod&a ericlenia...

T.K., a female, was born after full term and spontaneous delivery, weighing 2,260 g. Her parents were healthy and not consanguineous. There was no sibling. The patient was breast fed and appeared to be healthy until 6 months of age, when the parents wondered if she might be mentally retarded. Even beyond one year of age she could neither stand nor sit alone. There was no history of convulsions ...

Evidence has recently been presented for the natural occurrence of S-methylcysteine in kidney bean seeds (2) and in Neurospora crassa (3). The sulfoxide of S-methylcysteine has also been shown to occur in relatively high concentrations in the nonprotein nitrogen fraction of turnips, cabbage, and several other crucifers (4, 5). It is also of interest that the peptide, y-glutamyl-Smethylcysteine,...

The hormonal secretions of the adrenal cortex are known to be capable of causing a striking re gression of normal lymphoid tissue (cf. 22) and of exerting at least a transient growth-arresting ef fect on various types of lymphoid tumors (1, 2, 5, 6, 8, 12, 13, 20, 21, 24). In contrast, a selective action of corticosteroids on the metabolism of nor mal and malignant lymphoid tissue has not been ...

Eighteen cases of disseminated lupus erythematosus were verified by postmortem study in a series of 19,242 autopsies. Shortness of breath was the most common complaint and occurred in 16. Fourteen of this number had definite cardiac pathology. All 16 had definite pulmonary pathology. Fourteen cases had abnormal urinalysis. Of these cases, 7 had elevated blood nonprotein nitrogen values of over ...
