The Efect of Nano‑chitosan and Nano‑curcumin on Radiated Parotid Glands of Albino Rats: Comparative Study
Research Abstract
According to the histopathological examination, the gland in control group
appeared to be composed of parenchyma and connective tissue stroma. In radiated
group, serous acini lost its architecture and arrangement. The nuclei of serous acinar
cells showed hyperchromatism, pleomorphism, abnormal mitotic figures,
karyomegaly and perinuclear haloing. Intercalated ducts appeared dilated with
entrapped secretion, its lining cells with abnormal nuclear morphology. Striated
ducts appeared with stagnant secretion, cell proliferation and abnormal nuclear
morphology. Excretory duct appeared with distorted morphology, rupturing in lining
cell basement membrane, stagnant secretion and surrounded by hyalinized CT.
Blood vessels appeared engorged with red blood cells. In curcumin and chitosan
nanoparticles the parotid gland began to restore its normal histological structure.
