Input: Consider Input: Abstract: The effect of 17 beta-estradiol (17 beta E2) on anterior pituitary dopaminergic receptor (D2) content was studied in vitro in relation to PRL secretion. Anterior pituitaries from ovariectomized rats were incubated for short periods in medium 199, with or without the steroid. Dopamine (DA) receptors in partially purified pituitary membranes were quantified by equilibrium binding using [3H]spiperone; the PRL released into the incubation medium was analyzed by RIA. Addition of 10(-10) to 10(-6) M 17 beta E2 to the incubation medium of anterior pituitaries rapidly and reversibly decreased the number of DA receptors (P less than 0.01 to 0.001), while increasing PRL release, in a dose-related fashion. The maximal effect on both receptor numbers and PRL secretion was obtained with 10(-8) M 17 beta E2. This effect involved no change in receptor affinity (Kd = 0.11 +/- 0.01 nM in presence or in absence of 17 beta E2). This estrogen-induced decrease in DA-binding capacity was apparently not the result of the occupation of spiperone binding sites by the steroid, since after a 30-min incubation with 10(-8) M [3H]17 beta E2, no radioactivity was detectable on the partially purified membranes. Moreover, the presence of 17 beta E2 at the same time as the labeled D2 ligand did not modify the kinetics of association or dissociation of spiperone with pituitary membranes. This decrease in anterior pituitary DA receptor content and the increase in PRL release were already significant after a 7-min incubation in the presence of 10(-8) M 17 beta E2. Finally, these effects of 17 beta E2 were not mimicked by its 17 alpha-stereoisomer, nor by progesterone, or testosterone. These results suggest that the stimulatory effect of 17 beta E2 on PRL secretion may be due, at least in part, to the desensitization of anterior pituitary cells to DA. The steroid may produce this desensitization directly by decreasing the number of D2. The short latency of this effect likely discards the possibility of a genomic action of 17 beta E2.

Input: Consider Input: Abstract: Treatment and supervision of epileptic patients is part of specialist medicine. A possible change in the role of specialists and general practitioners in the care of these patients was explored by a questionnaire mailed to all Dutch neurologists and a random sample of general practitioners. Patients were also asked their opinion. The real situation was studied in a group of patients retrieved from the registers of general practitioners. Demographic, psychosocial, and epilepsy characteristics were sampled. Specialists tend not to want a change in their role; general practitioners desire a change. At present, patients do not want a change, but in future a change might be acceptable to them. More patients than expected were supervised by their general practitioner only. Their demographic and psychosocial characteristics did not differ from those in the population at large. Epilepsy characteristics corresponded with those in other studies.

Input: Consider Input: Abstract: To determine factors involved in left ventricular aneurysm formation after transmural anterior myocardial infarction, 79 patients with a first myocardial infarction who underwent cardiac catheterization within 6 months of infarction were evaluated. Patients who had received thrombolytic therapy were excluded. Patients were divided into four groups depending on the status of the left anterior descending artery and the presence or absence of a left ventricular aneurysm: Group I (n = 25): aneurysm with occluded left anterior descending artery; Group II (n = 27): no aneurysm and occluded left anterior descending artery; Group III (n = 23): no aneurysm and patent left anterior descending artery; and Group IV (n = 4): aneurysm with patent left anterior descending artery. Single vessel disease was more common in Group I (aneurysm) compared with Groups II and III (no aneurysm) (chi 2(4) = 12.8; probability value equal to 0.012). Collateral blood supply in the presence of an occluded left anterior descending artery was significantly less in Group I (aneurysm) compared with Group II (no aneurysm) (0.9 versus 2.4, p less than 0.001). The extent of coronary artery disease and collateral blood supply in Groups I and II were directly related (p = 0.012). Neither age, sex nor risk factors for coronary disease correlated with aneurysm formation. At a mean follow-up of 48 months, no differences were observed in the incidence of recurrent angina, new myocardial infarction, embolic events or sudden death. More patients in Group II underwent coronary artery bypass surgery. Total occlusion of the left anterior descending artery in association with inherent poor collateral blood supply is a significant determinant of aneurysm formation after anterior myocardial infarction. Multivessel disease with either good collateral circulation or a patent left anterior descending artery is uncommonly associated with the development of left ventricular aneurysm.
