Gal-1 immunoreactive cell numbers per 100 μm2 in the spleen. Immunoreactive cell numbers in the periarterial lymphatic sheath (PLS), germinal center and red pulp of control (C), just after stress (S), 30-min (SR30) and 60-min (SR60) survived spleens. Note that immunoreactive cell numbers in the PLS of SR30 and SR60 are increased compared with that of the control PLS although the differences are not statistically significant. Immunoreactive cell numbers in germinal center are evidently smaller than those in the PLS, however, the cell numbers of SR30 in this region are increased compared with the control group with statistical significance. *p < 0.05, **p < 0.01 (n = 4 rats in each group)
