作者:class="a3">佚名编辑:studa9ngns >< id=> 内容提要 目的:评价补肾益精方延缓老年雄性大鼠骨衰老与脑衰老的作用,探讨此方延缓整个机体衰老的机制。方法:40只24月龄SD雄性大鼠随机分为24月龄本底对照组、30月龄增龄对照组、补肾益精方低剂量组、补肾益精方高剂量组,每组各10只。低剂量组、高剂量组均自24月龄给药至30月龄。各组相应处理以后分别测定各组大鼠的骨参数(左侧股骨近段、中段、远段的骨密度和右侧股骨的弯曲断裂载荷)以及脑参数(脑组织M受体结合容量和胆碱酯酶活性)。结果:在骨方面,补肾益精方既能量效依靠性地增加大鼠股骨各段骨密度,又能量效依靠性地提高大鼠股骨弯曲断裂载荷;在脑方面,补肾益精方不仅能上调大鼠脑组织M受体结合容量,而且又能抑制大鼠脑组织胆碱酯酶活性。结论:补肾益精方具有同时延缓雄性大鼠骨衰老与脑衰老的作用;推测该方似通过神经内分泌免疫网络的介导从整体角度调整衰老机体肾虚精亏之异常。
