摘要: 本实验主要探讨了不同剂量(0.3 g/kg、0.6 g/kg、1.0 g/kg)的石花菜醇提物对小鼠高尿酸血症的拮抗效应。采用氧嗪酸钾盐对小鼠进行急性高尿酸血症造模,测定小鼠血清中尿酸(UA)、肌酐(Cr)和尿素氮(BUN)水平,以及小鼠肝脏匀浆液中黄嘌呤氧化酶(XOD)和腺苷脱氨酶(ADA)活性,HE染色观察其肾脏组织病理学变化。结果表明,与空白组相比,模型组小鼠血清中尿酸、肌酐和尿素氮水平显著升高(P<0.01),同时,XOD活性也得到显著升高(P<0.01),ADA活性升高(P<0.05)。与模型组相比,阳性对照组与各药物治疗组均能显著降低小鼠血清中尿酸、肌酐和尿素氮水平(P<0.01),同时,阳性对照组与各药物治疗组XOD活性均显著降低(P<0.01),而两组ADA活性则均无统计学差异。光镜下与模型组相比,阳性对照组和药物治疗组小鼠肾脏的肾小球损伤一定程度上恢复正常。总体而言,石花菜醇提物对小鼠高尿酸血症具有很大程度的缓解作用,其机制与体内抑制尿酸生成和促进尿酸排泄有关。

Abstract: The paper mainly discussed about the antagonistic effect of different doses (0.3,0.6,1.0 g/kg) of Gelidium amansii alcohol extract against hyperuricemia in mouse.The acute hyperuricemia of mouse model was made by oxonic acid potassium salt.The levels of uric acid (UA),creatinine (Cr),blood urea nitrogen (BUN) in mouse serum,the liver homogenization buffer of xanthine oxidase (XOD) activity,adenosine deaminase (ADA) activity and the histopathological changes of HE staining were measured.The results showed that,compared to the blank group,the model group significantly elevated the levels of UA,Cr,BUN (P<0.01) and the activity of XOD (P<0.01),ADA (P<0.05).In addition,the structure of renal corpuscle and renal tubule were damaged.Compared to the model group,the drug therapy group significantly reduced the levels of UA,Cr,BUN (P<0.01) and the activity of XOD (P<0.01).However,the activity of ADA had no statistical differences.To some degree,the drug therapy group can recover the structure of renal corpuscle and renal tubule induced by hyperuricemia.In general,the hyperuricemia in mouse was eliminated by G.amansii alcohol extract,which was related with the inhibition of uricogenesis and promotion of the uric acid excretion.
