中国医药学家经过研究证实,
决明子不仅能明目,
还有许多新的功效。
一、
防治近视眼、
老花眼
本品能使狗睫状肌中乳酸脱氢酶
(LDH)
活性显著提高。
它具有扩张末梢血管作用,
能改善视网膜及视神经的血液循环,
促进水肿吸收,
消除眼肌麻痹和视力疲劳,
因而可防治近视眼、
老花眼。
二、
防治白内障
老年性白内障病人房水及血清中
LDH
明显低于正常人,
服用决明子后,
眼组织
LDH
活性提高,可补偿老年人在白内障形成过程中所引起的
LDH
活性下降,
从而维持老年人眼组织中
LDH
的正常水平,
防止和延缓老年性白内障的发生和发展。
三?/b>
调节血脂
让实验性高胆固醇家兔连续服用本品
3
个月,
结果表明本品可抑制血清胆固醇升高和动
}
硬化斑块形成。
实验表明蒽醌甙是决明子降脂的主要成份之一,
因其有导泻作用,
能减少胆固醇的吸收及增加排泄,
通过反馈调节低密度脂蛋白代谢,
从而降低血清胆固醇水平,
延缓和抵制动
}
粥样硬化斑块形成。
四?/b>
降血压
本品可使复发性、
遗传性高血压大鼠收缩压明显降低,
比较治疗前后的收缩压可发现有显著性差异。
本品与利血平相比,
二者对自发性遗传高血压大鼠都具有降低血压作用,
而本品降低血压作用更明显。
本品与利血平对自发性遗传性高血压大鼠收缩压及舒张压的下降幅度
(平均下降值)
显著高于利血平,
而用量远远小于利血平,
对心率及吸收也无不良影响。
