Microscopic appearance of the spleen stained with H & E. Normal architecture of splenic tissue on light microscope after stained with H & E. The micrographs were taken at ×10 magnification in rats 4 weeks post treatment with ZALH (A), ZALL (B), ZAH (C), ZAL (D) and vehicle control (E). The doses were given via oral route repeatedly over a period of 28 days. White pulp (WP) and red pulp (RP) in experimental groups were shown to be similar in appearance compared to the control.
