BackgroundThis study aimed to assess the anxiety-depression levels and the perceptions of quality of life, as well as the factors affecting these variables, in adolescents with dysmenorrhea.MethodsThe participants included 60 adolescents with dysmenorrhea and 41 healthy adolescents between the ages of 12 and 18. This study used the Pediatric Quality of Life Inventory (PedsQL) for assessing the perceptions of quality of life, the State-Trait Anxiety Inventory (STAI) for measuring anxiety levels, and the Children’s Depression Inventory (CDI) for measuring depression levels.ResultsIt was determined that compared to healthy controls, the depression and anxiety scores were higher and the quality of life was impaired in adolescents with dysmenorrhea. In addition, it was shown that the depression and anxiety levels increased and the psychosocial health subscale scores of quality of life decreased with increasing dysmenorrhea severity. However, the likelihood of dysmenorrhea was found to be higher with increasing depression scores, while the anxiety levels had no effect on dysmenorrhea.ConclusionIn dysmenorrhea management, it is important to enhance awareness among pediatric clinicians and gynecologists regarding the associations between dysmenorrhea and mental problems.

Background:Diazinon (0,0-Diethyl 0-(1-6-methyl-2-isoprophyl 4 pyrimidinyl) phosphorothioate) (DI) is a very effective organophosphate pesticide, used widely in agriculture. Consequently, data on poisoning cases secondary to DI exposure are important. The DI may affect a variety of tissues, including liver. Silibinin is a pharmacologically active constitute of Silybum marianum, with documented antioxidant activity.Objectives:The aim of our study was to evaluate both histopathologically and biochemically whether silibinin is protective in DI induced liver damage.Materials and Methods:Thirty two Wistar albino rats were divided into four groups, as follows: 1) control group - oral corn oil was given; 2) DI group - rats were administered orally 335 mg/kg in the corn oil solution; 3) Silibinin group - 100 mg/kg/day silibinin was given alone orally, every 24 hours for 7 days; 4) Silibinin + DI group - DI plus silibinin was given. All rats were sacrificed at the end of experiment. Superoxide dismutases (SOD), glutathione peroxidase (GPX), nitric oxide (NO) and myeloperoxidase (MPO) were investigated in serum and liver tissue. In addition, serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) enzyme activities were evaluated. The liver tissue was evaluated histopathologically with Hematoxilin & Eosin dye.Results:Biochemically, ALT, AST, NO, MPO in serum and NO, MPO in liver tissue were found to be significantly higher in DI group, compared to control group (P < 0.001). In Group Silibinin + DI, serum AST, ALT, NO, MPO levels were significantly lower (P < 0.01), and both serum and tissue SOD activities were significantly higher, compared to DI group (P < 0.001). Diazinon induced histopathological changes in liver tissue were: severe sinusoidal dilatation, moderate disruption of the radial alignment of hepatocytes around the central vein, severe vacuolization in the hepatocyte cytoplasm, inflammation around central vein and portal region. In rats receiving both DI and silibinin, the DI induced changes accounted for less sinusoidal dilatation, vacuolization in the hepatocyte cytoplasm and the inflammation around central vein and portal region (P < 0.05).Conclusions:The DI was found to induce liver damage by oxidative stress mechanisms. Silibinin reduced the oxidative stress by inducing antioxidant mechanisms, thereby showing protective effect against DI induced liver damage. Further studies with silibinin should be performed regarding DI toxicity.

Itraconazole (ITZ) belongs to the triazole group of antifungals with potent keratinophilic and lipophilic features. Hepatotoxicity is one of its most remarkable features. Silibinin (SIL) is a plant used worldwide which is used in the treatment of many liver diseases and it is especially very well known for its hepatoprotective-cytoprotective effect. The aim of our study was to research the protective effect of SIL in ITZ-induced hepatotoxicity using biochemical and pathological tests. Liver enzymes and antioxidant enzyme activities were measured spectrophotometrically by using commercial kits. ALT and AST levels in ITZ group were significantly increased compared to the group, while the activities of GSH-Px and SOD had decreased (p < 0.05). When ITZ group was compared to ITZ + SIL group, AST, ALT, and levels of NO and MPO were significantly decreased, while the activities of GSH-Px and SOD were increased (p < 0.05). Histopathological evaluation showed that SIL significantly decreased periportal inflammation and parenchymal hepatocyte apoptosis in ITZ and ITZ + SIL groups (p < 0.05). Eventhough not statistically significant, partial improvement with the use of SIL has been detected (p > 0.05) in hepatocyte degeneration and multinuclear giant cell formation. According to the evaluation performed with comet assay method, ITZ leads to DNA damage, and the use of SIL significantly decreases DNA damage (p < 0.05). We have detected that the use of ITZ increases oxidative stress (MPO, NO), decreases antioxidant activity (SOD and GSH-Px), and leads to DNA damage and histopathological liver damage, whereas the use of SIL has a cytoprotective effect on the liver by increasing the antioxidant effect (SOD, GSH-Px) and by decreasing the oxidative stress (NO, MPO). ITZ causes the generation of ROS and leads to DNA damage and liver damage. SIL has a cytoprotective effect on the liver by increasing antioxidant enzyme activities, preventing the formation of ROS.

Abstract. The aim of the present study was to assess the protective effect of silibinin against methotrexate (MTX)-induced pulmonary toxicity. Rats were divided into four groups (MTX, MTX + silibinin, silibinin and control. MTX was injected intraperitoneally (i.p) into female Wistar rats (10 mg/kg/day for 3 days), which resulted in significant increases in the serum levels of alanine aminotransferase, aspartate aminotransferase and oxidant enzymes, including nitric oxide and myeloperoxidase. Furthermore, significant reductions were detected in the serum activity levels of the antioxidative enzymes, glutathione peroxidase and superoxide dismutase, when compared with the control group. However, administration of silibinin (100 mg/kg/day for 10 days, i.p.) was shown to ameliorate the MTX-induced pulmonary toxicity, as indicated by the normalization of the oxidative stress parameters. Furthermore, silibinin treatment was demonstrated to reduce the histopathological changes associated with MTX. In conclusion, silibinin exhibited protective effects against MTX-induced pulmonary toxicity, which may be attributed to its antioxidant activity.
