The Effect of Roaccutane on Development of Ovarian Follicles and Uterine Changes in Adult NMRI Mice Strain

Introduction: Roaccutane, Acuten, and Isotretinoin are derivatives of the vitamin A naturally found in human body. Since vitamin A is a fat-soluble vitamin, it is prescribed through controlling the amount of skin oil by forcing low-secreted sebaceous glands to treat severe skin acne with the risk of permanent scarring. Thus, we aimed to investigate the effects of Roaccutane on evolution of ovarian follicles and uterine, and possible attendant liver changes in adult NMRI mice. Materials and Methods: Roaccutane was orally administered by gavage at the doses of 0.5, 10, and 20 mg/kg for 21 days. Then, the mice were dissected, and the uterine, ovarian, and liver tissues were separated. The levels of Estradiol (E2), Follicle-stimulating hormone (FSH), Alanine transaminase (ALT), Aspartate transaminase (AST), and Alkaline phosphatase (ALP) were examined by ELISA test and chlorometric biochemical method. Results: Increase in the Roaccutane dose led to the damage to endometrium layers, and there were no significant changes in myometrium and perimetrium. Observations of the tissue of ovaries indicated the maturity of them. Significant reduction in the number of hepatocytes and rise of glands and blood vessels were the results of the liver damage. High level of liver enzymes (ALT, AST, and ALP) was the important reason for the liver damage. Hormonal findings through the increase of E2 and FSH also showed tissue damage. Conclusion: The results revealed the harmful effect of Roaccutane on evolution of ovarian follicles and uterine and liver changes of adult laboratory NMRI mice (either tissue or hormone).
