PURPOSE We tested the hypothesis that estrogen promotes improvement in urethral function and nerve regeneration following bilateral pudendal nerve crush in ovariectomized female rats. MATERIALS AND METHODS A total of 52 female rats underwent ovariectomy 6 days before bilateral pudendal nerve crush. Estrogen and sham capsules were subcutaneously implanted(More)
One reason that the central nervous system of adult mammals does not regenerate after injury is that neurotrophic factors are present only in low concentrations in these tissues. Recent studies have shown that the application of brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) acts to encourage the regrowth of motor and sensory fibers(More)
This study was conducted to determine the teratogenic effect of cocaine hydrochloride, alone or in combination with diazepam. Pregnant mice were administered cocaine hydrochloride at 10 and 20 mg/kg body weight intravenously (tail), and/or diazepam at 20 or 40 mg/kg b.w. by gavage. Combinations of diazepam and cocaine (20/10 and 40/20, respectively) were(More)
The outline of the arcuate nucleus in the human medulla oblongata was studied in a series of serial sections of brain stems of newborn and young children. The nucleus lies on the ventral aspect of the pyramid. At higher levels the nucleus lies on the ventral and medial aspect of the pyramid. In the upper regions of the medulla the two nuclei fuse together,(More)
Familial medullary carcinoma of thyroid (MCT) can be diagnosed early by measuring stimulated plasma calcitonin following provocation with 50 ml of oral whisky, or 0.5 microgram kg-1 i.v. pentagastrin. The calcitonin release, however, can be variable following both stimuli. To determine whether a humoral mechanism might be involved in mediating this(More)
