isotonic solution造句

• The amount of saline / isotonic solution needed in the band varies from patient to patient.
• My statement about lethality of non-isotonic solutions only applies to rapid and voluminous addition of liquids to the body.
• Isotonic solutions have the same salt concentration as the human body, whereas hypertonic solutions have a higher salt content and hypotonic solutions have a lower salt content.
• To produce a standard isotonic solution 6.5g NaCl, 0.42g KCl, 0.25g CaCl 2 and 0.2g of sodium bicarbonate is dissolved in one litre of distilled water.
• The sample is immersed in the isotonic solution and left for a period of 15 min, after which the meiofauna are shaken free of the substrate and again filtered out through a 45 ?m mesh and immediately returned to fresh filtered seawater.
• One proposed mechanism of intercalation is as follows : In aqueous isotonic solution, the cationic intercalator is attracted electrostatically to the surface of the polyanionic DNA . The ligand displaces a sodium and / or magnesium cation present in the " condensation cloud " of such cations that surrounds DNA ( to partially balance the sum of the negative charges carried by each phosphate oxygen ), thus forming a weak electrostatic association with the outer surface of DNA . From this position, the ligand diffuses along the surface of the DNA and may slide into the hydrophobic environment found between two base pairs that may transiently " open " to form an intercalation site, allowing the ethidium to move away from the hydrophilic ( aqueous ) environment surrounding the DNA and into the intercalation site.
