Abstract
OBJECTIVES: To describe immunological consequences induced by cryoablation against H22 cells in vivo. METHODS: Adult BALB/c mice underwent subcutaneous implantation of H22 cells. All of them were assigned into three groups randomly: group A (false surgery), group B (cryoablation) and group C (cryoablation plus Freund's adjuvant). Animals were sacrificed 1, 2 and 3 weeks after treatment. Serum IFN-γ and IL-4, Th1/Th2 in spleens and cytotoxicity were detected. RESULTS: Compared with that of group A, (1) INF-γ of group B was higher, but IL-4 was lower; cryoablation plus Freund's adjuvant enhanced these effects. (2) Th1/Th2 rose significantly in both group B and group C. (3) Strong cytolytic activity against H22 cells of group B and group C was found on day 7, 14 and 21. CONCLUSIONS: Our study showed a marked shift toward Th1 and IFN-γ expression after cryoablation, with an immuno-stimulatory effect against murine H22 hepatoma Cell.
