概括

氏丁酶ABC (chABC) 酶治疗显著增加了牛盘的运动范围和中性区域,为生物材料测试提供了比帕帕因更好的磁盘退化模型.

科学领域:

生物材料科学生物材料科学
再生医学是一种再生医学.
生物力学生物力学

背景情况:

用于椎间盘再生的生物材料需要使用器官培养模型进行临床前测试.
原生人类的磁盘是有限的,动物模型往往无法模仿人类的磁盘退化.
像chondroitinase ABC (chABC) 和papain这样的酶模拟生物材料注射研究的退行性变化.

研究的目的:

评估chABC对椎间盘的宏观和生物力学影响.
在注射到 chABC 处理的磁盘后评估水凝的分布.
将chABC效应与以前发表的Papain数据进行比较.

主要方法:

牛尾部份被分为四组:chABC,papain,PBS和对照组.
注射了酶或PBS,随后进行了7天的培养和模拟生理负荷.
运动范围,中立区域和圆盘高度在处理和加载前后都被测量.
微CT扫描可视化了注射后的水凝分布.

主要成果:

chABC增加了运动范围 (高达92.1%) 和中立区域 (高达79.4%),并降低了圆盘高度 (2.1毫米).
水凝注射通常会减少运动范围和中立区域,但在所有组中增加盘高度.
与帕帕因或PBS相比,chABC治疗允许更大的水凝注射量 (0.6毫升).

结论:

与papain相比,chABC治疗提供了一个优越的模型来模拟一般性磁盘退化.
帕帕因更好地模拟核切除,而这两种酶都保持了生物力学测试的环状完整性.
这些受酶处理的磁盘模型对于临床前生物材料评估非常有价值.

Degenerative Disc Disease I: Introduction

Degenerative Disc Disease I: Introduction

Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...

Degenerative Disc Disease ll: Pathophysiology

Degenerative Disc Disease ll: Pathophysiology

The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
