- 生物材料是一种生物材料.
背景情况:
- 玻璃眼瘤会导致由于眼内压升高 (IOP) 和视网膜质细胞死亡而导致不可逆转的失明.
- 传统的眼液难以穿透眼壁,限制了治疗的有效性.
- 微针 (MN) 为眼部疾病提供一种最小侵入性的局部药物输送途径.
研究的目的:
- 为了在微针阵列内制订一种天然的纳米输送系统,由Luteolin-loaded乳腺母乳衍生的外体体 (LUT-EX) 和.
- 为了评估这种新的系统对玻璃眼治疗的增强眼部输送,持续释放和治疗疗效.
主要方法:
- 异构体被分离出来,以大小 (50.83 nm) 和泽塔电位 (-21.89 mV) 为特征.
- LUT-EX配方显示48小时持续释放和高安全性 (IC50 = 356.3μg/mL).
- 与LUT-EX和 прополис集成的微针阵列显示出快速溶解 (<1分钟) 和机械稳定性 (>30N).
主要成果:

Open Angle Glaucoma: Treatment
554
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Angle Closure Glaucoma: Treatment
665
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
