研究了条件反射性抗体反应增强模型的建立。被试为49只雄性成年Wistar大鼠,采用糖精水作为条件性刺激,一种蛋白抗原卵清蛋白作为非条件性刺激配对给予大鼠,两者结合后,在初次抗体应答下降阶段再次单独给予条件刺激,用酶联免疫吸附法分时段检测抗体水平的变化。发现条件组在条件刺激后15,20,25天左右抗体水平明显高于对照组。这一过程与初次抗体应答的规律类似。这些结果证实经一次条件训练,单独给予条件刺激能诱导出明显的条件反射性抗体反应增高。

To establish the model of conditioned enhancement of antibody production. Forty - nine male and adult Wistar rats were used. A novel taste of saccharin was served as the conditioned stimulus (CS) and an injection of a protein antigen ovalbumin as the unconditioned stimulus ( UCS) . After a CS/UCS pairing was made, animals were re - exposed to the CS alone. Blood samples were periodically collected by tail incisions after re - exposure to the CS. The level of anti - OVA antibody production was measured by en...
