Abstract

In normal and pathological testicular tissue the influence of various fixing agents (Formalin solution, Bouins solution, Hellys solution, Carnoys solution) concerning the acoustical properties of testicular tissue was examined. By means of an ultrasound spectroscopic measurement technique the ultrasound damping was registered by calculation of the ultrasound damping coefficient alpha. The results show that the most lower alpha values were obtained by fixation with formalin solution as well in normal as in altered testicular tissue. The results of fixation according to Helly, Carnoy and Bouin did show markedly differences. Therefore, the fixation of testicular tissue using formalin solution is the best way for experimental examinations of the ultrasound damping behaviour.

摘要

在正常和病理睾丸组织中，研究了各种固定剂（福尔马林溶液、布因氏溶液、赫利氏溶液、卡诺氏溶液）对睾丸组织声学特性的影响。通过超声光谱测量技术，通过计算超声衰减系数α来记录超声衰减。结果表明，无论是正常睾丸组织还是病变睾丸组织，用福尔马林溶液固定时获得的α值最低。按照赫利氏、卡诺氏和布因氏方法固定的结果显示出明显差异。因此，使用福尔马林溶液固定睾丸组织是对超声衰减行为进行实验研究的最佳方法。
