Microscopic photograph of the liver in the female (A) and male (B) test group of rats and female (C) and male (D) test group of mice that received the repeated dose (100 mg/kg) of the Mentha mozaffarianii essential oil for 28 days. A and D: Apropos of the liver, the parenchymal cells of the liver normally have a cord-like arrangement of hepatocytes radiating outward from a central vein (CV) and sinusoid (S) structure. However, in B and C, the arrangements of the hepatocytes around the CV and S are disturbed.
