Öğe Black cumin may be a potential drug for development of carbontetrachloride-induced lung damage in rats(Mattioli 1885 S.p.A., 2016) Aslan, Abdullah; Boydak, Didem; Can, Muhammed İsmail; Kuloğlu, Tuncay; Başpınar, SerpilThe study examines whether Black cumin (Nigella sativa L.) plays a protective role against the damage in the lung by administering carbontetrachloride (CCl4) to rats. 28 male Wistar albino (n=28, 8 weeks old) rats were used in the study. The rats divided into 4 groups according to their live weights. The groups were: (i) Negative Control (NC): Normal water consuming group to which no CCl4 and Black cumin (BC) is administered; (ii) Positive Control (PC): Normal water consuming group to which no CCl4 is administered but BC is administered; (iii) CCl4 Group: Normal water consuming and group to which CCl4 is administered (1.5 ml/kg live weight, ip); (iv) CCl4 + BC group: CCl4 and BC administered group (1.5 ml/kg live weight, ip). Tissue apoptotic index was examined via TUNEL method. MDA (malondialdehyde) determination in lung tissue was made using spectrophotometer. As a results, MDA amount decreased in the CCl4 + BC group (6,33 ± 1,54 nmol/g) in comparison to CCl4 group (8,66 ± 1,58 nmol/g) whereas it was observed in the CCl4+BC group (15,35 ± 0,21%) that the apoptotic index (TUNEL results) decreases in comparison with the CCl4 group (27,48 ± 0,28%) thus approaching normal values. DNA damage ratio decreased in the CCl4 + BC group in comparison to CCl4 group. These results show that BC plant protects the lung against oxidative damage. © Mattioli 1885.Öğe Milk thistle impedes the development of carbontetrachloride-induced liver damage in rats through suppression of bcl-2 and regulating caspase pathway(PERGAMON-ELSEVIER SCIENCE, 2014) Aslan, Abdullah; Can, Muhammed İsmailAim: The objective of this study was to examine whether MT plays a protective role against the damage in the liver by administering carbontetrachloride (CCl4) to rats.

The rats divided into 4 groups according to their live weights. The groups were: (i) Negative Control (NC): Normal water consuming group to which no CCl4 and MT is administered; (ii) Positive Control (PC): Normal water consuming group to which no CCl4 is administered but MT is administered; (iii) CCl4 Group: Normal water consuming and group to which CCl4 is administered (2 ml/kg live weight, ip); CCl4+MT group: CCl4 and MT administered group (2 ml/kg live weight, ip). Tissue apoptotic index was examined via TUNEL method. MDA determination in plasma tissue was carried out using a spectrophotometer. As a Results, MDA amount decreased in the CCl4+MT group (3,65 ± 0,15 nmol/ml) in comparison to CCl4 group (4,25 ± 0,21 nmol/ml) whereas it was observed in the CCl4+MT group (12,62 ± 0,91 %) that the apoptotic index (TUNEL results) decreases in comparison with the CCl4 group (22,62 ± 0,91 %) thus approaching normal values. These results show that MT plant has a protective effect on liver. © Mattioli 1885.Öğe Nigella sativa improves the carbon tetrachloride-induced lung damage in rats through repression of erk/akt pathway(Bangladesh Pharmacological Society, 2015) Aslan, Abdullah; Boydak, Didem; Can, Muhammed İsmail; Kuloğlu, TuncayThe objective of this study was to examine whether Nigella sativa plays a protective role against the damage in the lung by administering carbon tetra-chloride (CCl4) to rats. Male Wistar albino (n=28, 8 weeks old) rats were divided into 4 groups: a) negative control: Normal water consuming group to which no CCl4 and N. sativa was administered; b) Positive control: Normal water consuming group to which no CCl4 was administered but N. sativa was administered; c) CCl4 Group: Normal water consuming and group to which CCl4 was administered (1.5 mL/kg, ip); d) N. sativa plus CCl4group: CCl4and N. sativa administered group (1.5 mL/kg, ip). Caspase-3, caspase -9, erk, akt protein syntheses were examined via Western blotting. Malondialdehyde determination in lung tissue was made using spectrophotometer. As a results, malondialdehyde amount was decreased in the CCl4 plus N. sativa group in comparison to CCl4 group whereas caspase-3, caspase-9 was increased and erk, akt had decreased. These results show that N. sativa protects the lung against oxidative damage.Öğe Protein expression product alterations in Saccharomyces cerevisiae(Mattioli 1885, 2017) Aslan, Abdullah; Can, Muhammed İsmailLemon is very rich in terms of vitamin C and thus it has antioxidant properties. In this study, the effects of lemon juice on cellular development in yeasts and protein expression have been examined. Seven groups were created in this study: 1: Control group; 2: K2Cr2O7 group; 3: 5 mM K2Cr2O7 + lemon juice (LJ) group; 4: 10 mM K2Cr2O7 + LJ group; 5: 15 mM K2Cr2O7 + LJ group; 6: 20 mM K2Cr2O7 + LJ group; 7: 25 mM K2Cr2O7 + LJ group. After sterilization, fruit juice (15%) and K2Cr2O7 were added different concentration to Saccharomyces cerevisiae (S. cerevisiae) cultures and the cultures were developed at 30 degrees C for 1h, 3h, 5h and 24 hours (overnight). S. cerevisiae cell growth was analysed by spectrophotometer, total protein alterations was identified by SDS-PAGE electrophoresis and measured with biuret method.
