Abstract
The tension developed in Rat skin by hydrothermal shrinkage is modified with ageing of the animals: the temperature of maximum tension decreases from birth to 1 month, then very slowly increases with age. At higher temperatures than that of maximum tension a relaxation occurs very rapidly in young Rats and in not yet senescent adult skins. These modifications appeared to be related to those of the nature of the intermolecular collagen cross-links with ageing.
摘要
水热收缩在大鼠皮肤中产生的张力会随着动物年龄的增长而改变
最大张力温度从出生到1个月时降低，然后随着年龄增长非常缓慢地升高。在高于最大张力温度的情况下，幼鼠和尚未衰老的成年鼠皮肤中会迅速出现松弛现象。这些变化似乎与分子间胶原蛋白交联性质随年龄增长的变化有关。
