为脱细胞化阴道基质开发安全的绝育方法对于组织工程至关重要. 抗生素和抗菌剂治疗有效地消毒人类阴道壁支架,而不会损害细胞外基质.
科学领域:
- 生物材料科学 生物材料科学
- 组织工程是组织工程.
- 再生医学是一种再生医学.
背景情况:
- 阴道重建治疗各种疾病,如失育,创伤,瘤和性别不一致.
- 目前用于阴道重建的治疗方法有局限性和并发症.
- 脱细胞化阴道矩阵 (DVM) 是阴道重建的一个有希望的替代方案.
- 对于临床安全性和功能来说,DVM的有效绝育是必不可少的.
研究的目的:
- 开发和评估一个无细胞化人类阴道壁支架的灭菌方法.
- 确保DVM的安全性和功能,以便在潜在的临床应用中使用.
主要方法:
- 在脱细胞化的人体阴道壁支架上测试了三种灭菌方法:单独使用化学脱细胞化,使用酸/过氧化 (PAA/H2O2) 脱细胞化以及使用抗生素和抗菌素 (AAE) 治疗进行脱细胞化.
- 绝育疗效通过受控的阴道微生物污染和随后的不育性测试来评估.
- 细胞外矩阵 (ECM) 结构完整性通过组织学染色来评估.
主要成果:
- 单靠脱细胞化,可以部分减少微生物污染物,但无法实现完全灭菌.
- PAA/H2O2杀菌严重破坏了ECM结构,使其不适合移植.

01:29Methods of Sterilization I: Physical Methods
As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation.
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...

01:30Methods of Sterilization II: Chemical Methods
In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...
