These studies attempt to analyze the basis of the estrogenic and antiestrogenic action of three nonsteroidal clomophene-type compounds as monitored by their ability to bind to immature rat uterine cytoplasmic estrogen receptor, transfer receptor sites to the nucleus, and elicit estrogenic responses (increased uterine weight and induction of the synthesis of(More)
In order to understand differences in the mechanism of action of estrogens and antiestrogens, it is essential to make comparisons between compounds with similar duration of action. Hence, in these studies, we compare the action of a long-acting estrogen (17alpha-ethinyl estriol-3-cyclopentyl ether, EE3CPE) and a long-acting antiestrogen (U-11,100AUA) on the(More)
Hamartoma of the spleen is a rare benign tumor. Only one spontaneously ruptured splenic hamartoma has been reported that presented with an acute surgical abdomen. A second case of a ruptured hamartoma of the spleen is illustrated; however, this case is unique in that it presented as a nonsurgical abdomen. This case stresses the importance of serial physical(More)
Muscle ion composition, Na-K-ATPase activity, tissue respiration, and transmembrane potential differences were measured after 28 and 56 days of ethanol consumption (6.2 g X kg-1 X day-1) or an isocaloric amount of glucose in 12 and 4 dogs, respectively. Ethanol and glucose were given as supplements to an otherwise nutritious diet. After 28 and 56 days of(More)
Magnesium deficiency was induced in a setting of an otherwise adequate diet in adult beagle dogs. Despite the development of severe hypomagnesemia (from 1.5 +/- 0.2 to 0.5 +/- 0.2 meq/liter) during the 10-wk study, Mg content of skeletal muscle fell only modestly (from 3.8 +/- 0.2 to 3.1 +/- 0.4, P less than 0.005, at 7 wk and 3.5 +/- 0.4 mM/100 g FFDS, NS,(More)
Studies were undertaken to ascertain the effects of structural modification of two well-known antiestrogens (CI-628 and U-11,100A) on their estrogenic and antiestrogenic potencies and temporal patterns of effectiveness in the immature rat uterus. Changes in the chemical structures of these anti-estrogens produce compounds with markedly different affinities(More)
We have examined the effect of ethanol on muscle blood flow at rest and during electrically stimulated exercise in five normal dogs using the isolated gracilis muscle preparation. Under pentobarbital anesthesia and mechanical ventilation, ethanol (15% in 0.9% NaCl) infused at 4 mL/min for 2 hr produced an arterial blood concentration of 268 +/- 10 mg/dL (X(More)
