Abstract:
Objective To investigate the changes in histological characteristics and collagen content in uterosacral and cardinal ligaments of pefimenopausal women in relation to relaxation of pelvic supports.Methods Twenty-eight subjects undergoing hysterectomies were selected,in which 14 cases were perimenopausal women with relaxation of pelvic support as the relaxation group and 14 women at perimenopansal age with leomyoma,cervical cancer,adenomyosis as the control group.Samples of cardinal ligaments and uterosacral ligaments were obtained at hysterectomies,and the tissues were shced and stained bv Masson's trichrome technique.Histological characteristics of the samples were studied and immunohistochemistry assay was applied to demonstrate the contents of collagen types I andⅢ.Results (1)The collagen in uterosacral ligaments and cardinal ligaments were stained blue by tlle MaSson's trichome technique.In comparison to the control group,the relaxation group had milder positive stains of the collagen and the stains were distributed in unequal intensities.Collagen content was arranged in loose pattern.Focal arrangement of the collagen was dense but fragmented.Collagen fibers were atrophic. (2)In immunohistochemistry assay and image analysis,collagen was positive in light to deep brown areas.In the relaxation group,positive units of collagen types I and III in cardinal ligaments were 13.8±2.1 and 9.6±2.4 respectively.Positive units of coHagen types I and Ⅲ of cardinal ligaments in the control group were 27.4 ±3.5 and 17.7 ±4.0 respectively.Difierences between these two groups were statistically significant (P
