Purpose: It was aimed to investigate the biochemical and immunohistochemical effects of ephedrine (EPH) in bilateral ovariectomized rats. Methods: Twenty-four Sprague Dawley female rats were divided into three groups: control group: The abdomen was opened and closed without any treatment; ischemia-reperfusion (IR) group: 2 h of ischemia followed by 2 h of reperfusion were allowed to cause IR injury; IR+EPH group: oral EPH solution (5 mg/kg) was administered for 28 days. Results: Biochemical parameters were statistically significant in group comparisons. Increased interleukin-6 (IL-6) expression, degenerative preantral and antral follicle cells and inflammatory cells around blood vessels were seen in IR group. Negative IL-6 expression was observed in seminal epithelial cells, preantral and antral follicle cells in IR+EPH group. While caspase-3 activity increased in granulosa cells and stromal cells in IR group, caspase-3 expression was negative in preantral and antral follicle cells in the germinal epithelium and cortex in IR+EPH group. Conclusions: The effect of apoptosis, which occurs with the signaling that starts in the cell nucleus, caused the cessation of the stimulating effect at the nuclear level after EPH administration, and a decrease in the antioxidative effect in IR damage and inflammation in the apoptotic process.
Objective: In this stud, we investigated the immunohistochemical staining of Sox-9 and Caspase-6 expression in placentas of pregnant woman with gestational diabetes mellitus (GDM). Materials and methods: Placentas of 20 healthy and 20 women with GDM were processed for routine histological tissue processing. The biochemical and clinical parameters of patients were recorded. Placentas were stained with hematoxylin-eosin and Sox-9 and Caspase-6 immunostaining. Results: In control group, SOX9 expression was negative in decidual and connective cells and endothelial cells. In GDM group, SOX9 expression was increased especially in the decidual cells. For the caspase6 expression, caspase 6 reaction was mainly in maternal region in control group. In GDM group, caspase 6 reaction was increased in decidual cells, in endothelial cells and in the syncytial nodes. Conclusion: Expression of SOX
Purpose: The aim of this study was to determine the protective and antioxidative effects of intensive exercise on streptozotocin (STZ)-induced testicular damage, apoptotic spermatognial cells death, and oxidative stress. Methods: 36 male Sprague Dawley rats were divided into three groups: control, diabetes, and diabetes+intensive exercise (IE) groups. Testicular tissues were examined histopathologically and antioxidant enzymes, including catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), and malondialdehyde (MDA) activity, as well as serum testosterone level, were measured. Results: Seminiferous tubules and germ cells were found to be better in the testis tissue of the intense exercise group than in the diabetes group. Diabetes suppressed antioxidant enzymes CAT, SOD, GPx and testosterone levels were significantly decreased, and increased MDA level in the diabetic group compared to diabetes+IE group (p < 0.001). Following four weeks of treatment, intensive exercise improved the antioxidant defense, significantly decreased MDA activity, and increased testosterone levels in testicular tissue in the diabetic group compared to diabetes+IE group (p < 0.01). Conclusions: STZ-induced diabetes causes damage to the testis tissue. In order to prevent these damages, exercise practice has become very popular nowadays. In present study, our intensive exercise protocol, histological, and biochemical analysis of the effect of diabetes on the testicular tissues is shown.
Aim: In this study, we investigated the immune activity of the Sox-9 and Cited-1 in women with placenta accreta. Materials and methods:20 healthy and 20 placentaaccreta were processed for routine histological tissue processing. Placentals samples were dissected and fixed in %10 formaldehyde solution. Samples were embedded in paraffin blocks. Clinical and biochemical parameters were recorded. Placental sections were cut from paraffin blocks and stained with Sox-9 and Cited-1 immunostaining. Results:In our study, control group showed negative cited 1 expression in decidual cells, root villi and connective tissue areas in general. Placenta accreta group showed increased cited 1 expression in degenerated decidual cells, fibroblastic cells and endothelium.In control group, Sox-9 expression was negative in the syncytial knots, in the vascular endothelial cells. Inplacenta accreta group, Sox-9 reaction was positive in the root villi, in the blood vessels, in the connective tissue. Conclusion: It was observed that the SOX-9 reaction was increased and inflammation was induced, depending on the differences in decidual cells, in the syncytial area and in the vascular endothelium in GDM placentas.It is thought that SOX-9 signaling processes are being determined and cited-1 may be stimulants that affect cell proliferation and angiogenesis regulation and affect placental development.
Objective: This study aims to detect a relationship between inflammatory markers, ductus venosus (DV) pulsatility index (PI), middle cerebral artery (MCA) PI, and umbilical artery (UA) systole to diastole ratio (S/D) and PI between pregnancies with intrahepatic cholestasis and control cases. Methods: This prospective study included 82 cases having intrahepatic cholestasis of pregnancy (ICP) and 80 gestational age-matched healthy control cases. The Doppler measurements (DV PI, MCA PI, and UA S/D and PI), inflammatory markers (neutrophil to lymphocyte ratio [NLR], platelet to lymphocyte ratio [PLR], mean platelet volume [MPV], and red blood cell distribution width [RDW]), and fetal and maternal outcomes were compared. Results: Patients with ICP had increased PLR value (p=0.019) and decreased lymphocyte count (p=0.004) compared to control cases. Also, there was a positive correlation between PLR value and the presence of ICP (χ2=5.774, p=0.016). There were no significant differences between ICP and control groups concerning NLR, RDW, MPV, and UA PI values. We found higher UA S/D, and DV PI values and lower MCA PI values in pregnancies with ICP compared to controls (p<0.001, p=0.026, and p=0.003, respectively). Conclusion: In ICP cases, the PLR value was significantly increased than the controls, but the NLR, RDW, MPV, and UA PI values were found to be similar to control cases. The UA S/D, and DV PI values were increased, and MCA PI was significantly decreased in the ICP group compared to healthy pregnancies. However, we could not demonstrate the benefit of Doppler measurements in predicting neonatal outcomes in ICP cases.
