Objective: To study the relationship between inflammatory reaction induced by abdominal irradiation and hematopoiesis. METHODS: 1 8-week-old male C5 7BL 6 / J mice were randomly selected and irradiated with 20 Gy of 60 Co in the abdomen. The irradiation source was 42 7 mm from the animal and focused at 4 cm 2. The dose rate was 2.4 Gy / min. The area of 1.6 cm2, including about 70% of the entire liver; irradiation of the intestine (including ileum, cecum and some near
