CONCLUSION
The purpose of this study was to determine the feasibility of using C.B-17 SCID mice
as an in vivo model system for the studying chemotherapeutic property of methotrexate
(MTX) on human leukemia. C.B-17 SCID mice were inoculated i.p. and s.c. routes with
CCRF-CEM cells. All mice of control group (group 1, 4) were not injected with MTX.
In group 2 and 5, MTX was injected i.p. or s.c. route once at 1 week after tumor
inoculation. In group 3 and 6, MTX was injected i.p. or s.c. route biweekly from five
weeks after tumor inoculation to become Results clearly showed that 100% of the
C.B-17 SCID mice implanted with CCRF-CEM cells developed palpable measurable
tumors within 4 ¡­5 weeks regardless of injection route (i.p. vs s.c.); however the tumor
cell line inoculated through i.p. route showed more disseminated systemic metastasis
than that of s.c. route. The survival time of C.B-17 SCID mice bearing CCRF-CEM
cells was significantly (p<0.05) increased in group 3 and 6 compared to other groups.
When comparing i.p. and s.c. routes, no significant differences in survival time were
observed. In addition, CCRF-CEM tumor growths were significantly (p<0.01) suppressed
by MTX treatment. In conclusion, the model system could well serve as a general
model of human leukemia by providing a means to evaluate the efficacy of various
chemotherapeutic agent as well as for basic research. Acknowledgement; This study
