Purpose: Ganulocyte-colony stimulating factor (G-CSF) has been widely used to treat neutropenia caused by chemotherapy or radiotherapy. The efficacy of recombinant human hematopoietic growth factors in improving oral mucositis after chemotherapy
or
radiotherapy has been recently demonstrated in some clinical studies. This study was designed to determine whether G-CSF can modify the radiation injury of the intestinal mucosa in mice.
Materials and Methods: One hundred and five BALB/c mice weighing 20 grams were
divided into nine subgroups including G-CSF alone group (¥°: 10 §¶/§¸ or ¥±: 100 §¶/
§¸), radiation alone group (7.5 or 12 Gy on the whole body), combination group with
G-CSF was injected subcutaneously for 3 days, once a day, from day -2 to day 0. Each
group was sacrificed on the day 1, day 3, and day 7. The mucosal changes of jejunum
were evaluated microscopically by crypt count per circumference, Villi length, and
histologic damage grading.
Results: In both G-CSF ¥°and ¥± groups, crypt counts, Villi length, and histologic
damage scores were not significantly different from those of the control one (p>0.05).
The 7.5 Gy and 12 Gy radiation alone groups showed significantly lower crypt counts
and higher histologic damage scores compared with those of control one (p>0.05). The
groups exposed to 7.5 Gy radiation plus G-CSF ¥° or ¥±showed significantly higher
crypt counts and lower histologic damage scores on the day 3, and lower histologic
damage scores on the day 7 compared with those of the 7.5 Gy radiation alone one
(p>0.05). The 12 Gy radiation plus G-CSF ¥°or ¥±group did not show significant
difference in crypt counts and histologic damage scores compared with those of the 12
Gy radiation alone one (p>0.05). Most of the mice in 12 Gy radiation with or without
G-CSF group showed intestinal death within 5 days.
Conclusion: These results suggest that G-CSF may protect the jejunal mucosa from the
acute radiation damage following within the tolerable ranges of whole body irradiation in
mice.
