pricing, demanders, and the supply of health care. | this paper is divided into three substantive sections. in the first section the conventional neoclassical paradigm is augmented by consideration of the agency relationship in which the physician is considered not only as the agent who controls the supply of health care, but also as the decision maker who articulates demand because patients forego this role and rely on "expert" advice. the next section is concerned with the effects of pricing on consumer demand and draws on the available empirica ... | 1978 | 422291 |
acute leukemia with unusual cytoplasmic inclusions: a cytochemical and ultrastructural study. | a 76-year-old woman with acute leukemia responded incompletely to prednisone and vincristine. cytochemistry of the blast cells demonstrated only focal alpha-naphthyl acetate and alpha-naphthyl butyrate esterase activity and focal coarse granular beta-glucuronidase activity, a pattern usually associated with acute lymphocytic leukemia. electron microscopy demonstrated primitive cells with features usually associated with promonocyte differentiation including prominent parallel arrays of microfila ... | 1978 | 222424 |
anaphylatoxin-induced shock and two patterns of anaphylactic shock: hemodynamics and mediators. | in the dog, different cardiorespiratory reactions were identified in two types of anaphylactic shock and in c5a-at (anaphylatoxin)-induced shock. all three types had in common a portal blood pooling with consequent decrease in the venous return, cardiac output, and arterial pressure. in anaphylaxis (a) of the first type, at a low titer of hemagglutinating antibodies, the latent period was 68 s and heart and lung function was unchanged. in the second type, at high titer, the latency was 19 s and ... | 1979 | 88165 |
immunologic studies of native and modified human factor viii/von willebrand factor. | factor viii/von willebrand factor (fviii/vwf) is a glycoprotein with a molecular weight greater than one-million daltons. two activities are associated with this large molecule: fviii procoagulant activity and vwf activity. incubation of fviii/vwf with proteolytic enzymes causes rapid inactivation of the fviii procoagulant activity but has little effect on the vwf activity or antigenicity. in an attempt to gain insight into the structural features required for these two activities, antisera were ... | 1979 | 88237 |
hippocampal evoked potentials and eeg changes during classical conditioning in the rat. | hippocampal evoked potentials (eps) and eeg responses were studied in rats, using a classical conditioning paradigm (water, us), with a spatially discontiguous cs-us arrangement in order to separate the cs and goal-related responses. in early training, when the orienting score was high, the tone cs, instead of eliciting a definite ep, usually reset hippocampal theta activity in phase, i.e. theta rhythm became time-locked to cs. with further training, orienting activity (ori) decreased to the pre ... | 1979 | 88362 |
systemic hyalinosis (juvenile hyaline fibromatosis). ultrastructure of the hyaline with particular reference to the cross-banded structure. | systematic hyalinosis (juvenile hyaline fibromatosis) is characterized by hyalinized skin lesions. electron microscopic examination of a hyalinized skin tumor from a 19-year-old man with this syndrome revealed that the hyaline was composed of ruthenium red-positive ultrastructures (granules, filaments, and a kind of cross-banded structure), indicating the presence of glycosamino-glycan or glycoprotein, and a small number of thin collagen fibrils. using a new ruthenium red staining method combine ... | 1979 | 88923 |
