UNLABELLED Quantitative reduction of portal blood flow following a portacaval shunt (PCS) adversely affects hepatocyte function, but does not alter HRES activity [L. P. Edgcomb , J. A. Knol , and F. E. Eckhauser . J. Surg . Res. 33: 233, 1982]. To determine whether similar changes occur after qualitative alteration of portal blood flow, portacaval transpositions (PCT) were constructed in six co...

INTRODUCTION AND AIM About 15% of hyperthyroid patients suffer from gastrointestinal symptoms such as diarrhea, constipation, nausea and early satiety the problem. Published reports on the topic of gastric emptying in hyperthyroidism are rare and discrepant in their results. PATIENTS AND METHODS Thirteen patients (8 women, 5 male; aged 41.92+/-1.491 SE yr) with a recently established diagnosi...

The role of the airway circulation in supporting mucociliary function has been essentially unstudied. We evaluated the airway clearance of inert, insoluble particles in anesthetized ventilated sheep (n = 8), in which bronchial perfusion was controlled, to determine whether airway mucosal blood flow is essential for maintaining surface transport of particles through airways. The bronchial branch...

Isotopic analyses of subglacially precipitated calcite from near a modern temperate glacier show that the delta(18)O (= (18)O/(16)O relative to standard mean ocean water) of the calcite records the delta(18)O of the ice from that glacier. It may therefore be possible to determine the delta(18)O of Pleistocene ice sheets on the basis of isotopic analyses of calcite formed under that ancient ice....

Triple density gradients of metrizamide in plasma (MP) were used to characterize label distribution in human leukocyte preparations incubated with 99mTc tin colloids. Less than 50% of the cell-associated radioactivity was specifically bound to leukocytes when heparinized blood was rotated with stannous fluoride colloid ([Tc]SFC). Labeling efficiency in leukocyte rich plasma (LRP) averaged 44%, ...

UNLABELLED The purpose of this retrospective study was to determine whether lymphoscintigraphy (LSG) for sentinel lymph node (SNL) mapping in a woman with a breast mass presents an unacceptable risk to her fetus. We assessed radiation-absorbed dose to various organs from 99mTc-sulfur colloid (TSC) LSG using standard internal absorbed dose assessment methodologies for both reference phantoms as ...

RATIONALE Alcoholics are more likely to have infections, mainly in the respiratory system. Alcohol seems to inhibit the immune system. Despite the extensive literature related to alcoholism, data related to the immune system are still not conclusive. OBJECTIVE The purpose of this study was to verify the influence of acute alcohol intake on colloid distribution in the organs of the mononuclear...
