AbstractAbstract PDF
The object of this study was to determine the difference of radiation effect in different fractional does and to establish optimal fractionation schedule on the whole-abdominal X-ray irradiation. Total 160 mice were irradiated with 150 KVP, 15 mA orthovoltage x-ray machine and two different fractionation (100 cGy/Fr. and 200 cGy/Fr.) were used. Body weight, hemoglobin and WBC count with differential count were analyzed according to the same amount of total dose, same field size and two different fractionation schedules. The results of this study were summarized s follows: There was no significant difference in body weight and hemoglobin concentration by sex or fractional dose. Leukopenic change was prominent in the 3,000 cGy irradiation group and the proportion of decrease was remarkable in the 200 cGy/Fr. Group than 100 cGy/Fr. Group. Progressive decrease of lymphocyte count and reciprocal increase of neutrophil count were noted as dose increment. The effect of the fractional does on WBC count and proportion of lymphocyte were significant. This suggests that judicious selection of fractional dose may be important in clinical radiotherapeutic practice.
