在生理盐水中保存5小时后，研究了其对兔膝关节前交叉韧带强度特性和组织学的影响。在+ 20[度]℃下，用生理盐水浸泡24小时。在+ 4[度]C，深度冷冻和10%的福尔马林中。每组8个膝关节。新鲜对照材料由14个膝关节组成。研究了载荷延伸曲线的大体形状、曲线的斜率、破坏时吸收的能量、破坏载荷、延伸破坏、记录仪载荷曲线的倾角和骨-韧带-骨制备的破坏部位。采用标准组织学方法。没有一种储存方式能令人满意地保存新鲜软结缔组织的抗拉强度特性。只有福尔马林固定对组织学研究是满意的。胶原组织的生物力学测试必须在移除后尽快进行。结果用显微照片、图表和表格说明。有10篇参考文献。
The effect on the strength characteristics and histology of the anterior cruciate ligaments from the knee joints of rabbits was studied after being in storage in saline for 5 hrs. at + 20[degree]C, in saline for 24 hrs. at + 4[degree]C, in deep freezing and in 10% formalin. In each group, 8 knees were Included. The fresh control material consisted of 14 knees. The parameters studied were the gross shape of the load elongation curve, the slope of the curve, the energy absorbed at failure, the failure load, elongation failure, dips in the recorder''s load curve and the failure site for the bone-ligament-bone preparation. Standard histologic methods were used. None of the modes of storage were satisfactory for the preservation of the tensile strength characteristics of the soft fresh connective tissue. Only formalin fixing proved satisfactory for histological studies. Biomechanical tests on collagen tissue must be performed as soon after removal as possible. The results are illustrated by photomicrographs, graphs, and tables. There is a bibliography of 10 references.
