Parameters quantifying dehydration in canine vocal fold lamina propria

Sulfated glycosaminoglycans in human vocal fold lamina propria.

INTRODUCTION The distribution, concentration and function of glycosaminoglycans in the various vocal fold tissues are still unclear. OBJECTIVE To evaluate the distribution and concentration of sulfated glycosaminoglycans in different layers of the human vocal fold according to gender and age. METHODS We used 11 vocal folds obtained from cadavers (7 men and 4 women) with no laryngeal lesion,...

Vocal fold superficial layer of lamina propria histology after the position of mucosa pediculated flap : canine experimental study Summary

[Vocal fold superficial layer of lamina propria histology after the position of mucosa pediculated flap: canine experimental study].

UNLABELLED Many techniques were applied to treat patients with sulcus vocalis and scarred vocal folds. Their results were not good enough. In the Technique of Vocal Fold Pediculated Mucosa Flap, an anterior pediculated flap of vocal fold is positioned on the superficial layer of the lamina propria, below the free margin. AIM To describe histological postoperative findings on the superficial l...

Collagen type I, collagen type III, and versican in vocal fold lamina propria.

OBJECTIVE To analyze the distributions of collagen type I, collagen type III, and versican in the lamina propria of the human vocal fold. DESIGN Cross-sectional analysis of cadaveric vocal folds of adult human larynges. SETTING Academic tertiary referral center. SUBJECTS Larynges harvested at autopsy from 10 adult men and 10 adult women. MAIN OUTCOME MEASURES Immunohistochemical reactio...

Establishing principles of macromolecular crowding for in vitro fibrosis research of the vocal fold lamina propria.

OBJECTIVES/HYPOTHESIS Vocal fold fibrosis represents a major disease burden. Screening of antifibrotic compounds could be facilitated by an in vitro fibrogenesis system. Limitations of existing models might be overcome by implication of the excluded volume effect. STUDY DESIGN In-vitro study. METHODS Vocal fold fibroblasts obtained from rats' lamina propria were cultured in four different s...
