    Comparison of the chronic effects of ribavirin and caffeic acid phenethyl ester (CAPE) on pancreatic damage and hepatotoxicity
    (E-Century Publishing Corp, 2014) Motor, Sedat; Alp, Harun; Senol, Serkan; Pinar, Neslihan; Motor, Vicdan Koksaldi; Kaplan, Ibrahim; Alp, Ayse
    This study was aimed to comparison of the effects of the chronic use of the Ribavirin and caffeic acid phenethyl ester (CAPE) on the pancreatic damage and hepatotoxicity in rats. Methods: The rats were given orally 30 mg/kg/day doses of Ribavirin for 30 days, and intraperitoneally 10 mu mol/kg doses of CAPE. The 37 rats were divided into 4 groups: (I) Control (n=7), (II) Ribavirin (R) (n=10), (III) CAPE (n=10), and (IV) R+CAPE (n=10). Results: Ribavirin and CAPE yielded similar results in terms of Serum, total antioxidant status (TAS), total oxidant status (TOS), amylase, lipase, and insulin compared to the control group. However, while Ribavirin provided similar results with the control group in terms of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) enzymes, the CAPE group had elevated AST and ALT levels compared to the control group. Histopathologic evaluations revealed that CAPE or Ribavirin had no degenerative effects on both the pancreas and liver tissues. In this way, the biochemical results were confirmed by the histopathologic results. Conclusion: It can be concluded that Ribavirin does not lead to any pancreatic damage and hepatotoxicity, and has more beneficial effects than CAPE on especially liver tissue.

    Effects of intralipid and caffeic acid phenyl esther (CAPE) against hepatotoxicity and nephrotoxicity caused by glyphosate isopropylamine (GI)
    (Sage Publications Inc, 2016) Alp, Harun; Pinar, Neslihan; Dokuyucu, Recep; Kaplan, Ibrahim; Sahan, Mustafa; Senol, Serkan; Karakus, Ali
    This study was aimed to investigate the protective effects of caffeic acid phenyl esther (CAPE) and Intralipid (IL) against hepatotoxicity and nephrotoxicity caused by acute intoxication of glyphosate (N-phosphonomethyl) glycine) (GI) in rats. Forty-nine Wistar Albino rats were randomly divided into seven groups as: I, Control; II, Intralipid (IL) (18.6 mL/kg, orally); III, CAPE (10 mu mol/kg, intraperitoneally); IV, GI (4 mg/kg/day, intraperitoneally); V, GI + IL; VI, GI+CAPE; and VII, GI + IL + CAPE. Total antioxidant status (TAS) and total oxidant status (TOS) levels were measured in serum samples. Tissues were analyzed with hematoxylin and eosin (H&E) staining protocol. Bcl-2, Bax, and caspase-3 were evaluated by immunohistochemical method. The results revealed that, in hepatic tissues, the TAS levels were lower and the TOS levels were higher in the GI group compared to other groups. In renal tissues, the TAS levels were significantly lower in the GI group than in the control, IL, CAPE, and GI + IL + CAPE groups. The TOS levels were significantly higher in the GI group than in the control group. Moreover, histopathological analysis revealed severe hepatotoxicity in the GI group. In the GI + CAPE + IL group, hepatotoxicity recovered significantly. Nephrotoxicity was also observed in the GI group and moderately reduced in the GI + CAPE group. Biochemical results were confirmed by histopathologic examination. The results also revealed that CAPE and IL, due to their antioxidant effects, have a decreasing effect against both hepatotoxicity and nephrotoxicity caused by GI. Therefore, CAPE and IL may function as potential agents for supportive therapy since they decrease organ damage, or may facilitate the therapeutic effects of the routine treatment of patients with GI poisoning.

    Protective Effects of Intralipid and Caffeic Acid Phenethyl Ester (CAPE) on Hepatotoxicity and Pancreatic Injury Caused by Dichlorvos in Rats
    (Springer/Plenum Publishers, 2016) Alp, Harun; Pinar, Neslihan; Dokuyucu, Recep; Sahan, Mustafa; Oruc, Cem; Kaplan, Ibrahim; Senol, Serkan
    The present study was aimed to the investigate the protective effects of caffeic acid phenethyl ester (CAPE) and intralipid (IL) on hepatotoxicity and pancreatic injury caused by acute dichlorvos (D) intoxication in rats. Forty-eight Wistar rats were randomly divided into seven groups each containing seven rats except control groups. The groups included control, D, CAPE, IL, D + CAPE, D + IL, and D + CAPE + IL. Total antioxidant status and total oxidative stress levels were measured by automated colorimetric assay. Tissues were evaluated using hematoxylin and eosin (H&E) staining. Tissues were analyzed with hematoxylin and eosin by using standard protocols. Also, Bcl-2, Bax and caspase-3 were evaluated by immunohistochemical method in liver tissue. Total oxidant status in control, CAPE, and IL groups were significantly lower, and total antioxidant status in the D + CAPE, D + IL, and D + IL + CAPE groups were significantly higher compared to the D group. CAPE and IL treatment decreased the apoptotic and mitotic cell count in liver tissue. Parenchymal necrosis caused by dichlorvos is observed in pancreas tissues of rats. Mild congestion and edema formation occurred in pancreas tissues following D + CAPE and D + IL therapies. These results indicate that CAPE and IL have the potential to decrease oxidative stress and hepatic and pancreatic injuries caused by acute dichlorvos intoxication. These drugs can be considered as a new method for supportive and protective therapy against pesticide intoxication.
