Outline of Final Research Achievements

The purpose of this study was to identify the cause(s) of stretch marks (striae distensae) with the actual human skin tissues obtained at the time of Caesarean delivery, by utilizing nursing science and engineering techniques. As a result, contrary to the hypotheses, neither the concentrations of collagen I and elastin in the dermis, nor the level of an inflammatory cytokine (TNF-alpha) was significantly related to the severity of stretch marks. However, there was a significant correlation between the echogenicity and the concentration of elastin in the dermis; it suggests the possibility of analyzing the elastic content of the skin by an ultrasound device. The main limitation of this study was that there were no subjects who had severe stretch marks; the severity of stretch marks might have been not enough to affect the skin parameters analyzed in this study.
