    Hyperglycemia, hypertension, dyslipidemia, and inflammation have been proposed to account for the development of nephropathy in diabetic subjects. The beneficial effects of enalapril on diabetic nephropathy are known. However, the effects of trimetazidine (TMZ) are still unknown. We aimed at comparing the effects of the enalapril and TMZ treatment on fibronectin expression, inducible nitric oxide synthase expression, urine proteinuria, blood glucose and glomerular, and mesangial structures of kidney in rats that take streptozotocin (STZ). In this study, 32 male Sprague-Dawley albino mature rats of 8 weeks, weighing 200-220 g were used. Diabetes was induced by intraperitoneal injection of STZ (60 mg/kg) for 24 rats. We made four groups (Group 1: control, non-diabetic rats (n = 8), Group 2: diabetes, without treatment (n = 8), Group 3: diabetes treatment with enalapril (n = 8), Group 4: diabetes treatment with TMZ (n = 8). The positive effects of renal tissue and tubules in the mesangium immunohistochemical were shown in TMZ receiving rat groups. These positive effects were in parallel with the reduction in fibronectin and I-NOS expression and reduction in the proteinuria. TMZ and enalapril treatment of diabetic rats and renal parenchyma in this study are shown to have positive effects on the different levels.

    Central nervous system metastatic epithelial ovarian cancer. Clinical parameters and prognostic factors: a multicenter study of Anatolian Society of Medical Oncology
    Seber, S; Turkmen, E; Harputoglu, H; Yesil, H; Arpaci, E; Menekse, S; Pilanci, K; Oruc, Z; Taskoylu, BY; Gumusay, O; Aksoy, A; Karaagac, M; Ozarslan, E; Yetisyigit, T
    Central nervous system (CNS) metastasis is a rare event in the course of late stage epithelial ovarian cancer (EOC); however its incidence is increasing in parallel with prolonged survival of patients. Objective: The authors assessed the clinical parameters and potential prognostic features in patients with CNS metastatic disease. Materials and Methods: Clinical data of the 33 patients from the participating centers were retrospectively collected and analyzed. Median age at the time of CNS metastasis was 57 years. Median time from the diagnosis of primiuy EOC until CNS metastatic disease was 22 months. Nearly half (45.5%) of the patients had single CNS metastatic lesions and all patients in the study group except two received radiotherapy as palliative treatment. Median overall survival (OS) from the time of CNS metastasis was 15 months (0-66). At univariate analysis only number of brain metastatic lesions (p = 0.001) and presence of extracranial disease (p = 0.004) were strongly associated with OS whereas multimodal treatment, size of metastatic lesions, platinum sensitivity, age, grade, and disease stage at presentation were not. Development of CNS metastasis carries a poor prognosis, however patients with single metastatic lesions and only intracranial metastatic disease can have prolonged survival after appropriate palliative management of their disease.
