This report describes the morphological changes observed in the brain of an untreated 27-year-old man with phenylketonuria, cortical blindness, and seizures. Golgi-Kopsch silver, cresyl violet, and hematoxylin and eosin stains were used to study cell

Of 52 infants who had died suddenly and were referred to autopsy, nine had lain on adult water beds for the first time; five had died as a result of accidents; two had died on water beds; two were in beds with widely spaced slats; and one had died as

Recurrent squamous cell cancer of the vulva metastasized via regional lymphatics. Hematogenous spread is late and unusual. A patient with metastatic disease presented with soft tissue mass in her thigh musculature. We believe this to be the first rep

The effects of dietary excesses of tryptophan, histidine, tyrosine or choline and of a tryptophan-free diet were examined on shock-induced fighting, muricide and jump-flinch thresholds. Following the tryptophan-free diet, shock-induced fighting and p

Dibutyryl cyclic AMP, infused intraventricularly in rats and mice, produced dosedependent increases in cyclic AMP and dose-dependent decreases in shock-induced rat fighting and isolation-induced mouse fighting and cricket attack, but not in cricket k

Pharmacological studies have demonstrated that shock-induced defensive fighting is modulated by manipulations of the serotonergic, noradrenergic and dopaminergic neurotransmitter systems. In the present study, regional changes in 5-hydroxytryptamine,

Certain biochemical characteristics of an adenylate cyclase that is activated by low concentrations of histamine ( K a , 8 μ m ) and that is present in cell-free preparations from the dorsal hippocampus of guinea pig brain have been studied. Histami

Soluble tyrosine hydroxylase from human pheochromocytoma, bovine adrenal medulla and rat striatum can be activated by Mg 2+ , ATP and cyclic AMP. In pheochromocytoma, this activation is due to a decreased Km for the pterin cofactor, whereas in adrena

Properties of N-acetylhistamine deacetylase in rat brain were studied, utilizing a sensitive coupled radioenzymatic assay. The Km for N-acetylhistamine for this deacetylase was 660 microM and its Vmax was 330 pmol/h/mg protein. N-Acetylhistamine deac

Cyclic nucleotides, particularly cyclic AMP, have been implicated as second messengers in neuronal activity. Attempts to demonstrate an association between endogenous cAMP or cGMP levels and rodent aggressive behavior have been only partially success
