ABSTRACT
Bisphenol A (BPA) used in plastic industry. This study evaluate ameliorative effect of vitamin E and selenium in combating BPA toxicity in spinal cord (SC) and submandibular glands (SMGs). Thirty rats divided into three groups [Group I, controls; Group II, BPA orally (25 mg/kg) three times a week, 60 days; Group III, BPA (25 mg/kg) plus vitamin E and selenium in water (1 ml/L/day)]. By histopathological, immunohistochemical, and biochemical investigations. Bisphenol A group showed degenerative alterations. SC gray matter showed pyknotic nuclei and white matter revealed neuropil degeneration. Myelinated fibers showed dispersed myelin. SMGs, exhibited vacuolated cytoplasm in acinar cells. Intense glial fibrillary acidic protein in SC and strong proliferating cell nuclear antigen in acinar and ductal cell nuclei of SMGs. Malondialdehyde elevated in SC and catalase decreased in SMG. Group III, SC and SMG revealed partial recovery. Vitamin E and selenium displayed protective effects against BPA toxicity in SC and SMGs.
HIGHLIGHTS
BPA had a neurotoxic effect on spinal cord of albino rats.
BPA causing degeneration of nerve fibers with axonal disappearance of white matter.
BPA caused GFAP proliferation and high MDA level in spinal cord.
BPA caused degeneration of submandibular gland’s acinar cells and duct system.
Both vitamin E and Selenium had a protective effect against BPA toxicity.
