Prolactin (PRL) increased basal dopamine (DA) release and attenuated amphetamine (AMPH)-stimulated DA release in vitro from rat corpus striatum in a concentration-dependent manner with 10(-5) M PRL being the most effective. The effects of PRL on DA…

1. Gamma-aminobutyric acid(A) (GABA(A)) receptor-mediated inhibition of pyramidal neuron dendrites was studied in area CA1 of the rat hippocampal slice preparation with the use of intracellular and extracellular recording and one-dimensional current…

Fluorescence studies of cytochrome b5 are complicated by the presence of three tryptophans, at positions 108, 109, and 112, in the membrane-binding domain. The cDNA for rabbit liver cytochrome b5, isolated from a lambda-gt11 library, was used to…

Whether nerve activity and active contraction of myotubes are essential for the assembly and initial differentiation of muscle spindles was investigated by paralyzing fetal rats with tetrodotoxin (TTX) from embryonic day 16 (E16) to E21, prior to and…

The pattern of regional expression of a slowtonic myosin heavy chain (MHC) isoform was studied in developing rat soleus intrafusal muscle fibers. Binding of the slow-tonic antibody (ATO) began at the equator of prenatal intrafusal fibers where…

We present a case of intrauterine infection with parvovirus B-19 and accompanying severe nonimmune hydrops at 26 weeks' gestation. The fetus showed progressive recovery on ultrasound. A term infant was delivered with hepatosplenomegaly as the only…

Protriptyline is the pharmacologic agent most commonly used to treat obstructive sleep apnea (OSA); however, its anticholinergic side effects make it intolerable to many patients. Because serotonin may be a central respiratory stimulant and because…

The progestin-induced withdrawal bleeding test has often been used in patients with amenorrhea to assess endogenous estrogen (E) production. The endometrial thickness measured by vaginal ultrasonography with a 5 MHz transducer is also dependent on E…

Several serotonergic and adrenergic agents were tested for an ability to interact with mu, delta, and kappa opioid binding sites. Spiroxatrine interacted nearly equipotently with all three opioid subtypes, yielding K(i) values near 110 nM. A number…

Thin section and freeze-fracture transmission electron microscopy were used to examine and identify the cytoplasmic and membrane structures in a cell line derived from a melanotic neuroectodermal tumor of infancy (MNTI). The cultured cells had a…
