Crenation
Definition:
(n.) A rounded tooth on the edge of a leaf.
(n.) The condition of being crenate.
Example Sentences:

(3) Our results indicate: 1) linear RBC pressure-flow behavior over a driving pressure range of 2 to 10.5 cm H2O with zero velocity intercepts at delta P = 0, thus suggesting the Poiseuille-like nature of the flow; 2) resistance to flow or "apparent viscosities" for normal RBC which are between 3.1 to 3.9 cPoise and are independent of driving pressure and pore geometry; 3) increased flow resistance (i.e., increased transit times) for old versus young RBC and for RBC made less deformable by DNP-induced crenation or by heat treatment at 48 degrees C; 4) increased mean transit time and poorer reproducibility when using EDTA rather than heparin as the anticoagulant agent.

(15) We demonstrate that the damage consists of lifting, crenation and detachment of endothelial cells, partially due to contracture and forceful redilation of the vessel wall.

(17) Electron microscopy of the endothelial layer of intimal explants showed dilatations in the intercellular junctions and cellular changes representing contraction--increased prominence of cytoplasmic filaments, nuclear crenation, and cytoplasmic protrusions--at 30 and 60 minutes.
(18) Raising this concentration reversibly decreased the degree of crenation.
(19) These amphiphiles immediately induced strongly crenated erythrocytes which during incubation shifted to less crenated erythrocytes or to stomatocytes.
(20) Osmiophilic granules with a homogeneous core, crenated membrane and narrow submembranous halo predominated in the columnar juxtacortical cells.
Solution
Definition:
(n.) The act of separating the parts of any body, or the condition of undergoing a separation of parts; disruption; breach.
(n.) The act of solving, or the state of being solved; the disentanglement of any intricate problem or difficult question; explanation; clearing up; -- used especially in mathematics, either of the process of solving an equation or problem, or the result of the process.
(n.) The state of being dissolved or disintegrated; resolution; disintegration.
(n.) The act or process by which a body (whether solid, liquid, or gaseous) is absorbed into a liquid, and, remaining or becoming fluid, is diffused throughout the solvent; also, the product reulting from such absorption.
(n.) release; deliverance; discharge.
(n.) The termination of a disease; resolution.
(n.) A crisis.
(n.) A liquid medicine or preparation (usually aqueous) in which the solid ingredients are wholly soluble.

(4) It has recently been suggested that procaine penicillin existed in solution in vitro and in vivo as a "procaine - penicillin" complex rather than as dissociated ions.
