Compared tensiometrical properties between non conserved and glycerin conserved fragments of bovine diaphragma's tendinous center, fibrous pericardium and parietal peritoneum
AbstractThe behaviour of the non conserved and 98% glycerin conserved specimens for periods of 30, 60 and 90 days of bovine diaphragma's tendinous center, fibrous pericardium and parietal peritoneum submitted to mechanical tests of traction, was observed in ten bovines between 30 months and 36 months of age, crossbreeds, males and females, collecting fragments of these aforesaid membranes in each animal. The diaphragma's tendinous center and parietal peritoneum did not suffered significant modification (p>;0.05) in the values of tension when compared to the resistance tests of traction of non conserved and 98% glycerin conserved membranes. However, all the evaluated tissues showed significant increase (p£0.05) of the elongation values when conserved in 98% glycerin for until 90 days. It was also observed that fibrous pericardium is the one which supports greaters tensions. So, it to was concluded, that glycerin is efficient to the conservation of biological membranes besides modifying its mechanical properties.
