    Objective: To investigate whether psoriasis and methotrexate used in its treatment cause liver fibrosis and eventually to evaluate the safety of methotrexate in treatment.Methods: 44 cases were included in the study. Methotrexate-using (group 1, n=14) and methotrexate-not-using (group 2, n=13) psoriasis patients were compared retrospectively with a healthy control group (group 3, n=17) according to mean shear wave rates obtainedResults: Mean shear wave velocities were calculated as 2.57 & PLUSMN; 1.13 m/sec in the patients using methotrexate, 2.31 & PLUSMN; 1.16 m/sec in the patients who did not use methotrexate, and 1.56 & PLUSMN; 0.62 m/sec in the healthy control group. While the average shear wave velocity of the 3rd group was found to be significantly lower than that of the 1st and 2nd groups (p=0.032; p=0.012), no significant difference was observed between the 1st and 2nd groups (p=0.755).Conclusions: Shear wave imaging with ARFI quantification findings revealed no evidence that methotrexate therapy is associated with liver fibrosis in psoriasis patients and we think that the increase in liver tissue stiffness in patients using methotrexate for psoriasis is secondary to the inflammatory process caused by psoriasis itself rather than methotrexate.

    Investigation of the anticancer effects of some plant seed oils with medicinal uses
    (Marmara Univ, 2023) Kurman, Yener; Duelger, Goerkem; Pasin, Ozge
    Cancer is an important health problem and responsible for a significant number of deaths worldwide. Chemotherapy resistance and related side effects prevent cancer treatment from reaching the desired level. In this study, we aimed to investigate the anti-cancer properties of Carthamus tinctorius, Salvia hispanica and Linum usitatissimum seed oils on hepatocellular (HepG2), colorectal (HCT-116) and gastric carcinoma (AGS) cell lines. Human umbilical vein endothelial cells (HUVECs) were used as control cell group. Cell viability of HepG2, HCT-116, AGS and HUVECs was determined by MTT method after treatment with various concentrations of Carthamus tinctorius, Salvia hispanica and Linum usitatissimum. Colorimetric elisa kit was used for quantitative determination of caspase-3 activation. Anti -migratory effect of Carthamus tinctorius and Salvia hispanica were investigated by wound healing assay. Carthamus tinctorius, Salvia hispanica and Linum usitatissimum seed oils significantly inhibited the proliferation of cancer cells. There was an insignificant decrease in the viability of HUVEC cells after seed oils treatments. Migration of HepG2 and AGS cells significantly suppressed by treatment of Salvia hispanica and Carthamus tinctorius respectively. Salvia hispanica and Carthamus tinctorius significantly increased caspase-3 activation in cancer cells. Our results showed that Carthamus tinctorius, Salvia hispanica and Linum usitatissimum exhibited a selective cytotoxicity against HepG2, HCT-116 and AGS cells without damaging normal cells.
