Effects of catecholamines on cyclic AMP (cAMP) levels and ion fluxes were examined in isolated rabbit ileal mucosa. The base-line cAMP level was unaffected by epinephrine (Epi), norepinephrine (Norepi), and isoproterenol. The theophylline-augmented cAMP level was decreased slightly be Epi in one series of experiments but not in another. Propranolol did not(More)
Newborn female Albino Swiss rats received testosterone propionate, dihydrotestosterone benzoate or oestradiol benzoate for 4 days after birth. The neonatal administration of all three hormones maintained neurones of the spinal nucleus of bulbocavernosus (SNB) complex in adulthood at levels intermediate between those found in normal females (approximately 40(More)
BACKGROUND We know that the social conditions in which children live exert a strong influence on their health; yet, we do not know how children's experience of these conditions of daily life shape their perspectives of health. METHODS Through ethnographic research methods, the first author spent 1 year with the 14 6-year-old children involved in this(More)
Prior studies have indicated that effects of cholera enterotoxin (CT) on the small intestine are delayed in onset and involve an interaction with adenyl cyclase in the mucosa. It has also been shown that the administration of cycloheximide to rabbits in doses which inhibit crypt cell mitoses (20 mg/kg), diminishes CT-induced fluid production in jejunal(More)
Both cholera enterotoxin and certain prostaglandins have been shown to stimulate intestinal fluid secretion in vivo, to cause ion flux changes in vitro similar to those caused by addition of cyclic 3',5'-adenosine monophosphate (cyclic AMP), and to activate intestinal mucosal adenyl cyclase. It has been suggested that the effects of the enterotoxin on(More)
We have investigated the interaction between tumor cells and specific cells in their microenvironment using myeloma as a model. The role of myeloma-induced osteoclastogenesis in the disease was studied ex vivo. Myeloma plasma cells freshly purified from patients' bone marrow attracted committed osteoclast (OC) precursors (n = 9; P < 0.01) and in 22(More)
The effects of several prostaglandins (PG) and a highly purified preparation of cholera enterotoxin (CT) on intestinal mucosal adenyl cyclase activity and the effect of CT on intestinal mucosal cyclic 3',5'-adenosine monophosphate concentration were determined in guinea pig and rabbit small intestine and were correlated with the effects of the same agents(More)
