These studies examined the contribution of serotonin (5-HT) to the control of prolactin (PRL) and vasoactive intestinal peptide (VIP) messenger RNA expression in rat anterior pituitary. Daily injection of rats with the biosynthetic precursor to…
A rat muscle spindle typically contains four intrafusal fibers - one nuclear bag(2), one nuclear bag, and two nuclear chain fibers. We compared the sequence of formation of the three intrafusal fiber types among the tibialis anterior (TA), soleus…
OBJECTIVE: To identify educational strategies for resident training in nursing home care deemed successful by a large number of programs. DESIGN: A mail survey with three follow-up mailings. PARTICIPANTS: Directors of accredited internal medicine and…
Detection of renal vascular disease offers the opportunity to cure a patient with hypertension as well as to avert severe renal damage and lifelong dependence on dialysis. The crucial first step is to suspect renovascular lesions. Clues include the…
Percutaneous transluminal angioplasty and renal artery bypass surgery are the most effective means of treating renal vascular disease and the hypertension it causes. Selection of the most appropriate treatment depends on the nature of the underlying…
Behavioral change reduces risk of HIV infection and development of AIDS. We compared 206 inner-city women who were randomly assigned to a 4-session AIDS-prevention group or to one of two controls, a health-promotion group or a no-intervention group.…
Reactive arthritis is an important source of morbidity. It is acquired through infectious agent diarrhea (food poisoning) or from sexual contact. Recognition is important because it allows a therapeutic approach that usually results in improvement of…
Pulmonary blastoma is a rare primary neoplasm of the lung. Approximately 25% of the reported, cases have occurred in pediatric patients. The authors found 45 cases of these tumors in children aged less than or equal to 16 years, and report two more…
Patients with Proteus mirabilis bacteremia at a large community teaching hospital during a 13-year period (1980-1992) were retrospectively reviewed. There were 176 patients whereof 44 (25%) had polymicrobial bacteremia. The median age of patients was…
Objective: Investigation of the hypothesis that the infusion of 10 ng/kg/min prostacyclin (epoprostenol) (PGI(2)) improves O-2 uptake in patients with hyperdynamic septic shock. Design: Prospective, single cohort design. Setting: ICU, university…
OBJECTIVE: To describe a patient who developed significant metabolic abnormalities in response to a low-level theophylline ingestion. CASE SUMMARY: An 18-year-old man was examined after ingesting theophylline 3 g in a suicide attempt. Although his…
This study examined the output of the central nucleus of the inferior colliculus to the medial geniculate body and other parts of the nervous system in the mustached bat (Pteronotus parnellii). Small deposits of anterograde tracers (horseradish…
Physicians, parents or guardians, and the community all have an important role in preventive care for adolescents. Adolescents desire more interaction with their primary care providers. Physicians can influence the health care of adolescents by…

The etiology of arthritis in Hyaenidae has been a subject of conjecture. While osteoarthritis has been considered, the observation of an erosive arthritis prompted a systematic survey of museum specimens to define its nature and frequency.…
1. The objective of the experimentation was to determine whether nicotine (NIC, 0.8 mg/kg subcutaneously administered) would produce a conditioned place preference (CPP) in rats confined for thirty min to their less-preferred side in a three…
This study was conducted to determine whether increased myocardial energy demand plays a role in norepinephrine (NE)-induced left ventricular (LV) dysfunction. A range of arterial pressure-heart rate (P-R) products (myocardial energy demand) was…
Hippocampal CA1 cells possess several varieties of long-lasting synaptic plasticity: two different forms of long-term potentiation (LTP) and at least one form of long-term depression (LTD). All forms of synaptic plasticity are induced by afferent…
Monoamine-activated alpha 2-macroglobulin (alpha 2M) has recently been shown to inhibit the growth and survival of cholinergic neurons of the basal forebrain (Liebl and Koo: J Neurosci Res 35:170-182, 1993). The mechanism of this inhibitory effect is…
Monoamine-activated alpha 2-macroglobulin (alpha 2M) has been shown to inhibit beta-nerve growth factor (NGF)-promoted neurite outgrowth and the survival of embryonic sensory and forebrain neurons, whereas normal alpha 2M has little or no such…
In this experiment, we examined the modulatory effects of testosterone on the parkinsonism-inducing drug 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in two strains of mice. Orchidectomized male CD-1 and C57/B1 mice were implanted with either…
The management of traumatic biliary fistulas is controversial. New ideas in nonsurgical treatment have recently evolved, in part because of the rapid advancement of laporoscopic surgery. Three major concepts are important in managing biliary…
Sarcoidosis is a disease of unknown etiology which is characterized pathologically by widespread noncaseating granulomas involving multiple organ systems. We report a case of sarcoidosis presenting as a ventilation-perfusion mismatch on a lung scan.
