Novel distribution pattern of fibrinolytic components in rabbit tissues extract： a preliminary study
Lu XG Wu XG Xu XH Gong XB Zhou X Xu GB Zhu L Zhao XY 《Journal of Zhejiang University. Science. B》2007,8(8):570-574
Objective: The purpose of this work was to investigate the distribution pattern of fibrinolytic factors and their inhibitors in rabbit tissues. Methods: The components of the fibrinolytic system in extracts from a variety of rabbit tissues, including tissue plasminogen activator (tPA), plasminogen activator inhibitor-1 (PAI-1), plasminogen (Plg), plasmin (Pl) and α2 plasmin inhibitor (α2PI), were determined by colorimetric assay. Results: The tissue extracts in renal, small intestine, lung, brain and spleen demonstrated strong fibrinolytic function, in which high activity of tPA, Plg and Pl was manifested; whereas in skeletal muscle, tongue and stomach, higher activity of PAI-1 and α2PI showed obviously. Also excellent linear correlations were found between levels of tPA and PAI-1, Pl and α2PI, Plg and Pl. In related tissues, renal cortex and renal marrow showed distinctly higher activity of tPA and lower activity of PAI-1, with the levels of Plg and Pl in renal cortex being higher than those in renal marrow, where the α2PI level was higher than that in renal cortex. Similarly, the levels of tPA, Plg and Pl in small intestine were higher than those in large intestine, but with respect to PAI-1 and α2PI, the matter was reverse. In addition, the fibrinolytic activity in muscle tissue was lower, however, the levels of tPA, Plg, and Pl in cardiac muscle were obviously higher than those in skeletal muscles, and the levels of PAI-1 and α2PI were significantly lower than those in skeletal muscle. Conclusion: Our data demonstrate that a remarkable difference of the fibrinolytic patterns exists in rabbit tissues, which has probable profound significance in understanding the relationship between the function of haemostasis or thrombosis and the physiologic function in tissues. 相似文献

花粉是延年益寿的佳品．为了多方面探讨花粉的抗衰老作用，本文就花粉对肌肤的抗衰老作用作了探讨。先将花粉破壁，制备出花纷提取液，并经真空浓缩成花粉浓缩液，再将花粉浓缩液与赋型剂、促进剂乳化成花粉制剂．花粉制剂用于临床，观察参试者颜面皱纹变化。参试者每日使用2—3次，连续使用40天，皱纹有效消除率达45．5％，连续使用60天，有效率达86％以上，表明花粉提取液能有效防止肌肤衰老，为花粉抗老防衰功能研究提供了有益的参考。 相似文献

松针提取液抗疲劳作用研究 总被引：11，自引：0，他引：11
目的 :研究松针提取液的抗疲劳作用。方法 :将松针提取液分 3个剂量组 ,即 4 g/kg·d ,8g/kg·d ,12g/kg·d给小鼠灌胃 ,对照组为生理盐水。 2 0天后小鼠力竭游泳造成疲劳 ,测定超氧化物歧化酶 (SOD)、乳酸脱氢酶 (LDH)、血红蛋白 (Hb)、血乳酸 (LA)、血尿素氮 (BUN)等指标。结果 :8g/kg·d组为最佳用量 ,12g/kg·d组无明显优势 ;SOD和LDH的活性、Hb含量均有显著性升高 ,LA和BUN含量均有显著性降低。结论 :松针提取液具有抗疲劳作用而提高机体的运动能力。 相似文献

目的:探究火麻提取物(EFC)对D-半乳糖(D-gal)诱导的衰老大鼠认知的影响。方法:随机选取3月龄的雄性大鼠48只,分为6组,每组8只:正常对照组(control)、D-gal模型组、EFC(200mg/kg)预防组、EFC(400mg/kg)预防组、D-gal+EFC(200mg/kg)组、D-gal+EFC(400mg/kg)组,对各组大鼠进行Morris水迷宫的测试。结果:D-gal模型组大鼠搜索平台潜伏期增加,寻找隐藏平台的路径更曲折。而EFC(400mg/kg)预防组和治疗组大鼠潜伏期明显缩短,寻找平台的路径则比较简单。这些结果表明,EFC可以有效地预防由D-gal引起的大鼠空间记忆障碍。结论:火麻仁提取液在一定程度上可以改善D-gal致衰老大鼠的认知功能。 相似文献
