摘要:
背景/客观: ,也称为gotu kola,也称为gotu kola,是一种热带药用植物,是马达加斯加山脉,东南亚和南非。众所周知,具有生物学活性,包括伤口愈合,抗炎,抗糖尿病,细胞毒性和抗氧化作用。这项研究的目的是确定agagainst agagainst age-rel提取物的功效ated eye degeneration and to examine their physiological activities.
MATERIALS/METHODS: To determine the effects of CA-HE50 (50% EtOH extract) on retinal pigment cells, we assessed the cytotoxicity of CoCland oxidized-A2E in ARPE-19 cells and observed the protective effects of CA-HE50抗甲基 - 亚硝基(MNU)诱导的C57BL/6小鼠的视网膜损伤。特别是,我们测量了与凋亡和抗氧化以及视紫红质/OPSIN的蛋白质水平有关的因素。 We also measured glucose uptake to characterize glucose metabolism, a major factor in cell protection.
RESULTS: Induction of cytotoxicity with CoCland oxidized-A2E inhibited decreases in the viability of ARPE-19 cells when CA-HE50 was administered, and promoted glucose在正常条件下吸收(<0.05)。此外,在MNU-Indu的背景下,CA-HE50抑制视网膜的变性/凋亡CED毒性(<0.05)。特别是,以200 mg/kg的速度Ca-He50抑制了pro-Caspase-3和pro-Poly-3和Pro-Poly(ADP-核糖) - 聚合酶的裂解,并保持了与正常对照水平相似的核因子红细胞2相关因子2和Heme 2相关因子2和血红素氧酶-1的表达。低紫红素/OPSIN表达的表达比正常对照中的水平更高。
结论: 一系列实验证实CA-HE50可以有效地抑制或预防年龄相关的眼睛损伤/退化。基于这些结果,我们认为使用CA-HE50开发与年龄相关的眼睛变性有关的药物或功能性食品是值得的。
