摘要

为了研究黄粉虫纤溶活性蛋白(Tenebrio Fibrinolytic Proteins

TFP)的免疫原性及其抗血栓作用，本研究将纯化的TFP经皮下注射免疫小鼠，间接ELISA法检测小鼠血清中的抗体含量及抗体效价；小鼠灌胃TFP后，取血浆检测凝血酶时间(thrombin time

TT)、凝血酶原时间(prothrombin time

PT)、活化部分凝血活酶时间(activated partial thromboplastin time

APTT)、组织型纤溶酶原激活剂(tissuetype plasminogen activator

tPA)和其抑制物(plasminogen activator inhibitor

PAI)，角叉菜胶使小鼠尾部形成血栓，测量血栓形成长度.结果显示，TFP免疫小鼠后产生特异性抗体且随着免疫次数的增加，抗体含量逐渐升高，末次免疫后产生的抗体效价为1∶ 640；TFP可以显著延长TT，增强t-PA的活性，抑制PAI的活性，同时显著抑制由角叉菜胶引起的小鼠尾部血栓的形成.这说明TFP具有良好的免疫原性且具有一定的抗血栓作用.

Abstract

To study the immuongenicity and antithrombotic effect of Tenebrio Fibrinolyric Proteins(TFP)

mice were immunized with purified TFP by subcutaneous injection

then the antibody content and antibody titer were detected by the optimal ELISA method. Mice were gavaged with purified TFP

then thrombin time(TT)

prothrombin time(PT)

activated partial thromboplastin time(APTT)

tissuetype plasminogen activator(tPA) and plasminogen activator inhibitor(PAI) activity were detected.The results show that the specific antibody is found after TFP immunized mice and the antibody content increases when the number of immunization rises. The specific antibody titer is 1∶640 after the last immunization.The TT of mice is remarkably prolonged after using TFP. The tPA activity increases while the PAI activity decreases. Meanwhile the average thrombosis length of tail is significantly reduced.This shows that the TFP has good immunogenicity and antithrombotic effect.
