Objective: he aim of the study was to determine the influence of maternal sodium valproate (SVP) on neonatal neuroendocrine (hypothalamic-pituitary-adrenal; HPA)-cytokines and oxido-inflammatory axes. Methods: Pregnant rats (Rattus norvegicus) were orally administered (by gavage) SVP (50 mg/kg) from gestation day (GD) 8 to lactation day (LD) 21. Results: The elevation in serum corticotropin-releasing hormone (CRH), corticosterone, and adrenocorticotropic hormone (ACTH) levels was highly significant at postnatal days (PNDs) 14 and 21 in both dams and neonates of the maternal SVPtreated group relative to those in the control group. However, hypercortisolism (cortisolemia) was highly significant in neonates at both PNDs 14 and 21 while in dams, it was not significantly increased at LD 14 but was at LD 21. This disruption caused adverse effects on maternal food consumption and maternal/neonatal body weight. The maternal SVP treatment resulted in higher levels of neonatal serum adrenaline, noradrenaline, neuropeptide Y (NPY), tumor necrosis factor-alpha (TNF-α), leptin, interleukins (IL-1β, IL-17, IL-4, IL-6 & IL-2), transforming growth factor-beta (TGF-β), and prostaglandin E2 (PGE2), and lower levels of neonatal serum growth hormone (GH), insulin growth factor-1 (IGF-1) and adiponectin at both PNDs. This administration also induced the oxidative stress in neonatal cerebrum and cerebellum at both tested PNDs via the production of free radicals (malondialdehyde; MDA & nitric oxide; NO) and reduction of antioxidant parameters (glutathione; GSH, superoxide dismutase; SOD & catalase; CAT). Conclusion: Maternal SVP treatment stimulated neonatal stress-brain (HPA) axis, resulted in an oxido-inflammatory state, and disrupted the neuroendocrine-cytokines axis, and generally neonatal health.

Background: Radiographic examination is often used in dentistry to evaluate tooth extraction complications. X-ray used in radiographic examination, however, has negative effects, including damage to DNA and inflammatory response during wound healing process. Purpose: This study aimed to analyze the effects of X-ray irradiation on transforming growth factor beta 1 (TGF-ß1) expression and number of inflammatory cells in tooth extraction sockets. Method: Thirty rats were divided into three groups, which consist of control group (with a radiation of 0 mSv), treatment group 1 (with a radiation of 0.08 mSv), and treatment group 2 (with a radiation of 0.16 mSv). These rats in each group were sacrificed on days 3 and 5 after treatment. Inflammatory cells which were observed in this research were PMN, macrophages, and lymphocytes. Histopathological and immunohistochemical examinations were used to calculate the number of inflammatory cells and TGF-ß1 expression. Obtained data were analyzed using SPSS 16.0 software with one way ANOVA and Tukey’s HSD tests. Result: There was no significant decrease in the number of PMN. On the other hand, there were significant decreases in the number of macrophages and lymphocytes in the sacrificed group on day-5 with the radiation of 0.16 mSv. Similarly, the most significant decreased expression of TGF-ß1 was found in the group sacrificed on day 5 with the radiation of 0.16 mSv. Conclusion: X-ray irradiation with 0.08 mSv and 0.16 mSv doses can decrease TGF-ß1 expression and number of inflammatory cells in tooth extraction sockets on day 3 and 5 post extraction.

Background. Transforming growth factor-beta (TGF-β) and hepatocyte growth factor (HGF) are inflammatory cytokines which function as key regulators of immunological homeostasis and inflammatory responses. They have been linked to inflammatory bowel diseases (IBD). In this study, we aim to assess the levels of TGF-β and HGF and other inflammatory markers in patients with IBD and correlate them with the disease activity. Study Design. A cross-sectional study involving 100 patients with ulcerative colitis (UC) and 100 patients with Crohn’s disease (CD) and 50 control subjects. TGF-β and HGF levels were measured and correlated with disease activity. Results and Conclusion. Serum levels of TGF-β and HGF were significantly higher in IBD patients compared with the control group. In the UC group, the levels of HGF and TGF-β were significantly higher than in the CD group. Levels of TGF-β and HGF correlate with the activity of IBD.

This study aimed to determine the occurences of mice brain ventricles dilatation that congenitally infected with Toxoplasma gondii (T. gondii) as a marker of hydrocephalus and cellular changes in the brain. A total of twenty pregnant mice (11.5 days pregnacy) were divided into 2 groups, which were control (P1) group and treatment (P2) group. The mice in the treatment group were infected with 101 tachyzoites of T. gondii. All mice were maintained until delivery. The newborn mice were sacrificed and their brain were removed and fixed in 10% buffered formalin to prepare histology slides with HE staining for observation of ventricular width, TUNEL assay for apoptosis observation, and immunohistochemistry for the expression of transforming growth factor beta (TGF-β) observations. The data were analyzed using t test and linear regression. The results showed that ventricular width and apoptosis index significantly increased (P<0.01) in the treatment group compared to control group, but there was no difference in the expression of TGF-β (P>0.05) in both groups. Dilatation of ventricle correlated with the apoptotic index of brain cells but did not correlated with the expression of TGF-β.
