Spleen sections stained with anti-CD3+ antibodies to realize T cells. It shows the marginal zone and lymphatic follicles in the control (a, b), DM (c, d) and DMWP (e, f) groups. T cells are strongly distributed in all zones, especially PALS, in the spleen sections of the diabetic rats. Interestingly, WP greatly reduced the number of T cells in the tissues of diabetic rats (×400). Values shown are the mean count of the CD-3+ cells in both MZ and F (g) ± SD. *shows the significance (p < 0.05) in comparison to the control group.
