A syndrome of hereditary tyrosinemia in mink (Mustela vison Schreb.).

A hereditary disease in mink (Mustela vison Schreb.) leading to death when the affected kits are about six weeks old has been investigated. The disorder is inherited as a simple autosomal recessive character. Strongly elevated plasma tyrosine concentration is an outstanding feature of the disease. An enzyme defect in tyrosine aminotransferase (EC 2.6.1.5) or 4-hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27) is considered together with the possibility of a parallel between the disease in mink and the disease tyrosinosis or hereditary tyrosinemia in man.

Effectiveness of certified nurse-midwives. A prospective evaluation study.

A prospective evaluation study of the effectiveness of the services of certified nurse-midwives demonstrated that in a hospital setting the care of low-risk maternity patients provided by nurse-midwives was as effective as the provided by house staff physicians. A total of 438 low-risk maternity patients were studied. Selected outcomes pertaining to the prenatal period, labor and delivery, and early infancy demonstrated, with two exceptions, no significant differences. The two exceptions were: (1) overcompliance with appointment attendance was more common among the nurse-midwifery group of patients; (2) a higher rate of forceps delivery was reported among the house staff group of patients.

Fluorescence of biogenic monoamines in the human dental pulp.

Biogenic monoamines in the adrenergic nerve terminals of the human dental pulp are demonstrated by the fluorescence method of Falck and Owman. Unmyelinated nerve fibers from nerves along alveolar blood vessels may enter the pulp, although pulp nerves are composed largely of myelinated fibers. The existence of a few sympathetic fibers is demonstrated by the fluorescence method, and possible drug effects are considered.
