The pathophysiology of cold injury was examined by cooling a hind leg of an anesthetized New Zealand white rabbit. A flow probe and a thermocouple were placed in the leg to be cooled to monitor the blood flow and tissue temperature. After baseline measurements, the leg was cooled with a freezing mixture up to 0 degrees C, which was followed by rewarming. The other leg served as control. In the ...
Plants are always exposed to various stresses. We have focused on freezing stress, which causes serious problems for agricultural management. When plants suffer freeze-induced damage, the plasma membrane is thought to be the primary site of injury because of its central role in regulation of various cellular processes. Cold tolerant species, however, adapt to such freezing conditions by modifyi...
OBJECTIVE The present study aimed to clarify the structural recovery, and to compare the time course of morphological changes in trabeculae and the process of bone mass change in rat tibiae following temporary immobilization of hind limb by sciatic neurectomy or nerve freezing. METHODS In 11-week-old male Fischer 344 rats, 4-5 mm of the sciatic nerve was removed (neurectomy group) or frozen b...
Maximum freezing tolerance of Arabidopsis thaliana L. Heyn (Columbia) was attained after 1 week of cold acclimation at 2[deg]C. During this time, there were significant changes in both the lipid composition of the plasma membrane and the freeze-induced lesions that were associated with injury. The proportion of phospholipids increased from 46.8 to 57.1 mol% of the total lipids with little chang...
