Abstract
Circulating levels of pregnancy-specific beta 1 glycoprotein have been determined in a number of physiological situations in late pregnancy. The apparent variation in five subjects studied over a 24-hour period was not in excess of that due to the assay. Excess variation was apparent in 2 of 11 subjects studied daily for up to 8 days, and in 6 of 16 patients studied serially during labour.

Abstract
Four cases of malignant hyperphenylalaninemia (MHPA) are described. Pretreatment serum phenylalanine levels were 1.5, 3.0, 2.4, and 0.9 mmoles/l. Dihydropteridine reductase (DHPR) deficiency was proven in one patient by assays on cultured fibroblastic cells and was presumed in her sibling and in another deceased patient whose parents' fibroblastic cells show approximately 50% of normal enzyme activity. DHPR and phenylalanine hydroxylase deficiency were excluded by assays on liver obtained at autopsy in the 4th patient. Parenteral administration of tetrahydrobiopterin (BH4) corrected the hyperphenylalaninemia and increased the levels of catecholamines and 5-hydroxy-indoles in the one patient studied in life, but BH4 did not reach the cerebrospinal fluid. A 3-wk course of BH4 therapy had no clinical effect. Oral biopterin was absorbed and excreted in the urine, but did not alter the serum phenylalanine level. The frequency of MHPA in Australia was estimated as 7 in 258 patients with phenylketonuria.

Abstract
Assessment of urinary dihydroxanthopterin is proposed as a simple method of recognition of patients with malignant hyperphenylalaninemia (MHPA). High levels of urinary dihydroxanthopterin are found in untreated patients with phenylketonuria (PKU) or with dihydropteridine reductase (DHPR) deficiency. After dietary control of the serum phenylalanine level in PKU, the urinary dihydroxanthopterin falls to near normal levels. In DHPR deficiency urinary dihydroxanthopterin levels are high even when serum phenylalanine levels are in the range achieved on dietary treatment. Low levels would be expected in patients with defects in tetrahydrobiopterin synthesis even before dietary treatment. Confirmation of the diagnosis of different forms of MHPA then requires more detailed studies, but dietary treatment of other PKU patients can proceed with confidence.

Abstract
A 12-year-old boy with recurrent skin ulceration, chronic generalized lymphedema, and mild mental retardation was found to excrete massive amounts of dipeptides, most (but not all) of which had proline or hydroxyproline as the carboxyl terminal residue. Glycylproline predominated. Prolidase deficiency was demonstrated in red blood cells and in fibroblastic cells. Prolidase activity was present in continuous lymphoid cell cultures at the same low level observed in control cells.

Abstract
7,8-Dihydroxanthopterin in identified in urine from phenylketonuria and lethal hyperphenylalaninemia patients. Because 7,8-dihyroxanthopterin is readily oxidised to xanthopterin, most of the characterisation was performed on xanthopterin. This finding indicates a gross disturbance of tetrahydrobiopterin metabolism in these patients. 7,8-dihydroxanthopterin or a related pterin may play a role in the pathogenesis of neurological symptoms in phenylketonuria and lethal hyperphenylalaninemia.
