(11) The role of the baricity of local anaesthetic solutions in determining the distribution of local anaesthetics injected into the subarachnoid space (and hence the level of anaesthesia) has been challenged.
(12) We conclude that individual anatomical properties may play a more important role than, for example, baricity in subarachnoid distribution of a local anaesthetic solution.
(13) Besides the patient's position other factors may influence the cephalad spread of sensory blockade such as baricity of local anesthetics, speed of injection, dose, volume, barbotage and size of needle.
(14) The strains are characterized by genetic linkage between attenuation, accelerated penetration of baby hamster kidney cells, and efficient neutralization by the E2-specific monoclonal antibodies R6 and R13; selection for change in one property simultaneously selected for change in the other two (Olmsted, R. A., Baric, R. S., Sawyer, B.
Barium
Definition:
(n.) One of the elements, belonging to the alkaline earth group; a metal having a silver-white color, and melting at a very high temperature. It is difficult to obtain the pure metal, from the facility with which it becomes oxidized in the air. Atomic weight, 137. Symbol, Ba. Its oxide called baryta.
Example Sentences:

(7) Only 31 percent of the patients had colonoscopy or double-contrast barium enema x-ray beyond the neoplastic area before surgery.
(8) We conclude that routine use of Golytely is preferable to methods involving catharsis and standard tap water enemas for barium enema examination, on the grounds that it is equally effective, yet more convenient for patients and for the radiology department, and reduces total costs.
(9) Barium (5 mM) had little effect and cobalt slightly reduced the ACh-induced Ca2+ response.
