ABSTRACT
Objective: In order to study how to accelerate the reconstitution immunofunction in BMT mice, first of all, we established a immunodeficiency model of BMT in BALB/C mice. Then BMT mice were injected with PCD-hIL-2 directly into skeletal muscle, and treated with traditional Chinese medicine. Methods: The experiment groups are designed as(A)Chinese medicine + PCD-hIL-2;(B)PCD-hIL-2;(C)Chinese medicine +hIL-2;(D)Chinese medicine;(E)hIL-2;(F)BMT;(G)normal control;(H)radiation control. Results: We compared groups A B C D to E or F groups, found(1)The splenocytes/thymocytes count increase obviously.(2)Killing activity of NK cell rises obviously in vivo.(3)The response of splenocytes、thymocytes、BM cells to mitogen goes up.(4)The reactivity of splenocytes to foreign IL-2 goes up. (5)CFU-GM count is increased. Conclusion: The expression of hIL-2 is very low by nude DNA injection ,but it is enough to have biological function and therapeutic effect .If only Chinese medicine was applied, the immunological condition was obviously recovered.
