title: Folic Acid and Grape Seed Extract Prevent Azathioprine-induced Fetal Malformations and Renal Toxicity in Rats.
abstract: Azathioprine (AZA) is an important drug commonly used in the therapy of the autoimmune system disorders. It induces many hazard effects that restrict its use. The present study was designed to investigate the influence of AZA on the fetal development and renal function and its co-administration with either folic acid (FA) or grape seed extract (GSE). The effects of administration of GSE or FA on AZA toxicity by gavage simultaneously for 4 weeks were studied by determining the changes in kidney histology, the glutathione level (GSH), and lipid per oxidation content as malondialdehyde in the kidney tissue. Additionally, their effects on the fetal development were investigated. Azathioprine induced a renal damage as indicated from the pronounced changes in histological structure, a significant increase in serum urea and creatinine, and malondialdehyde content in the kidney tissue. Meanwhile, the GSH activity was significantly decreased. Co-treatment with GSE significantly minimized the previously mentioned hazard effects of AZA by ameliorating the antioxidant activity. At this point, FA induced a nonsignificant protective activity. The results also revealed that administration of FA or GSE at 6th to 15th day of gestation did not altered fetal development. While, AZA administration clearly disturbed fetal development as indicated from a significant decrease in fetal weights. Furthermore, co-administration of both drugs significantly minimized similarly the hazards of AZA on the fetal development. It may be concluded that GSE and FA are a useful remedies. Maternal administrations of either both are protective agents against AZA-induced fetal malformations. Grape seed extract was more active than FA in potentiating the antioxidative defenses for controlling AZA-induced oxidative renal damages. Copyright © 2016 John Wiley & Sons, Ltd.
