Effect of TS treatment on CD68 cells in mice receiving 60Co γ-radiation. Jejunum samples from TS- or vehicle-treated and irradiated (11 Gy) mice were collected 1, 2 and 4 h after irradiation. After fixation and processing, radiation-induced inflammatory response was evaluated by scoring cross-sections of jejunum for CD68-positive cells per villus by immunochemistry. Representative areas are shown (×600 magnification) in photomicrographs. TS-treated mice had significantly fewer CD68-positive cells 2 and 4 h after irradiation compared with vehicle-treated mice. *Denotes statistically significant difference between indicated groups. Two sham irradiated groups were used as controls: one was untreated and other was injected with TS.
