Osmotic shrinkage as a factor in freezing injury in plant tissue cultures.
Haplopappus gracilis and Acer saccharum tissue culture cells are extremely sensitive to freezing injury, and exhibit a decrease in survival from 98% at -1 C to 4% at -3 C (Haplopappus) and 92% at -3 C to 13% at -5 C (Acer) when suspended in distilled H(2)O, seeded at -1 C, and then cooled by 0.1 C/minute. Similar results are obtained when cells are suspended in growth medium. The extent of shri...

Arterial thrombosis is generally recognized as the proximate event responsible for most acute ischemic syndromes resulting from atherosclerotic vascular disease.1,2 The majority of such thrombi (60% to 80%) occur at sites of fissure or rupture of a thinned fibrous cap overlying a lipid-rich atherosclerotic lesion with intimal and adventitial inflammation, and the remainder occur over areas of s...
متن کاملMechanism of Hyperosmotic and Extracellular Freezing Injury
The vome of isolated protoplasts of rye (Secale cereale L. cv Puma) in a suspending solution at constant concentration is shown to be neglgbly changed by tensions in the plasma membrane which approach that tension necessary to lyse them. This aflows a detailed investigation of the plasma membrane stress-strain relation by micropipette aspiration. Over periods less than a second, the membrane be...
