Zhao S, Yang Y, Liu W, Xuan Z, Wu S, Yu S, Mei K, Huang Y, Zhang P, Cai J, Ni J, Zhao Y - J. Cell. Mol. Med. (2014)

Bottom Line: Radical oxygen species level was also reduced by H(2) treatment.Finally, we found that H(2) could regulate the polarization of CD4+ T cells and the level of related cytokines.This study suggests H(2) as an effective radioprotective agent on immune system by scavenging reactive oxygen species.

Morphology of spleen after in vivo γ-radiation. (A) Spleens of mice with control morphology are comprised of both red and white pulps. (B) Spleens of mice 2 days after in vivo γ-radiation. (C) Spleens in mice pre-treated with H2 at 2 days after irradiation. (D) Spleens of mice 14 days after in vivo γ-radiation. (E) Spleens in mice pre-treated with H2 at 14 days after irradiation.

fig02: Morphology of spleen after in vivo γ-radiation. (A) Spleens of mice with control morphology are comprised of both red and white pulps. (B) Spleens of mice 2 days after in vivo γ-radiation. (C) Spleens in mice pre-treated with H2 at 2 days after irradiation. (D) Spleens of mice 14 days after in vivo γ-radiation. (E) Spleens in mice pre-treated with H2 at 14 days after irradiation.

Mentions: The splenic morphology was characterized by using the following subjective descriptors: control, diminished, depleted when compared with normal group (Table 2). Cellularity of white pulp decreased significantly after exposure to 5 Gy irradiation. Both width and density of the layer of lymphocytes appeared to decrease obviously. Cellularity of red pulp was obviously reduced and accompanied by tissue congestion. And the resulting morphology was described as depleted (Fig. 2B). Compared with Figure 2B, the reduction in cellularity of white pulp and red pulp was less remarkable and the morphology was characterized as diminished (Fig. 2C). Fourteen days post exposure, cellularity of both white pulp and red pulp in radiation group and H2 group recovered, while the structure in radiation group was much disorganized and the density of cells were lower compared with the H2 group (Fig. 2D and E).
