The rate of collagen maturation in rat and human skin.

摘要: Hydrothermal Isometric Tension (HIT) relaxation was observed at the boiling point in rat, cat and human skin samples of different ages, after raising temperature from 37° to 100°C a rate 1.15°C/min.A Maxwellian nearly zero point. A given velocity constant characterized tissue whether experiments were performed under pressure or tensile stress. However, decreased as function age for all three species during period studied. Moreover, same cats aged 1 5 years, rats 9 28 months children birth 10 years.We propose model, based on well known rubber-elastic properties denatured collagen network. In this model (1) HIT decreases an exponential time bond scission along polymeric chains; (2) process is proportional...
