女贞子多糖和菟丝子多糖的协同抗衰老作用及其机制

The synergistic effect and its mechanism of PLLA and PCCL on antisenility

目的研究女贞子多糖和菟丝子多糖的协同抗衰老作用及其机制。方法用两因素两水平正交法设计实验,用D半乳糖造衰老小鼠模型,各试药组同时每天每公斤体重ig女贞子多糖∶菟丝子多糖50mg∶50mg、50mg∶200mg200mg∶50mg、200mg∶200mg,观察其对衰老模型小鼠免疫器官及抗氧化系统的影响。结果女贞子多糖∶菟丝子多糖每天每公斤体重50mg∶50mg、50mg∶200mg、200m∶50mg、200mg∶200mgig能使衰老模型小鼠胸腺指数和脾脏指数不同程度升高;肝和肾组织中MDA不同程度下降SOD及GSHPX活力不同程度提高;脑组织中LF不同程度下降。统计学分析表明,女贞子多糖和菟丝子多糖对各实验指标有交互作用。结论女贞子多糖和菟丝子多糖联用有协同抗衰老作用,两药的最佳组合是女贞子多糖∶菟丝子多糖50mg∶200mg,其机制可能与提高免疫功能,清除氧自由基、活性氧及抗脂质过氧化有关。

Aim To study the synergistic effect and its mechanism of polysaccharide from Ligustrum Lucidum Ait(PLLA)and polysaccharide from Cuscuta Chinensis Lam (PCCL)on antisenility. Methods To observe the effect on immune organs and antioxidation systems of mice with senile model caused by D-galatose (D-gal) and meanwhile administered with PLLA∶PCCL 50 ∶50 mg or 50 mg ∶200 mg or 200 mg ∶50 mg or 200 mg ∶200 mg·kg -1·d -1 designed by orthogonal method. Results Thymus index and spleen index differently rose,MDA differently dropped,activities of SOD and GSH-PX differently ascended in liver and kidneys,LF differently descended in brain of mouse with senile model administered with 50 mg∶50 mg or 50 mg ∶200 mg or 200 mg ∶50 mg or 200 mg ∶200 mg·kg -1·d -1 PLLA ∶PCCL.The statistical analysis indicated that the combination of PLLA with PCCL yielded of notable or extremely notable reciprocal effect on the experimental index of antisenility. Conclusion The combination of PLLA with PCCL can yield notable synergistic effect on antisenility,the optimal combination of both drugs is PLLA ∶PCCL 50 mg ∶200 mg, its mechanism is probably connected with immunity inhacement,eliminati on of oxyen free radicals and active oxyen and antilipoperoxidation.
